También es necesario hacer alusión a factores exógenos que han incidido en la proyección de prioridades políticas durante el periodo en análisis, y especialmente a la existencia de una coyuntura regional, con países con visiones y objetivos comunes cuya actuación parte de un enfoque de derechos en el cual el derecho a la salud tiene uno de los primeros órdenes de prelación. Esta coyuntura regional vio el surgimiento de bloques regionales como la Unión de Naciones Suramericanas, que ha tenido una incidencia marcada tanto en la agenda de salud subregional, como en la agenda de salud global. Asimismo, se pueden mencionar las actuaciones de otros bloques subregionales que han avanzado en materia sanitaria dentro del Organismo Andino de Salud y el Mercado Común del Sur.

3.2.4 Apply Quality Threshold (QT) clustering on models passing the interface size filter. A QT cluster is defined by the translational and rotational distances between a reference and referred ligand structures, where the distance must be smaller than 3 Å and 8°, respectively. The distance thresholds correspond to translational and rotational perturbations that will be applied during local-refinement docking, and thus, in contrary to RMSD based clustering, will allow a seamless transition between global and local docking calculations. Rotational and translational distances can be calculated with the Superimpose application (http://cleftxplorer.googlecode.com/files/cX.zip), which is part of the CleftXplorer software package , :

It is well known that erythropoiesis, as well as iron demand, changes throughout life in humans as a consequence of an increase in blood volume. Also, complete blood cell count (CBC) values differ slightly depending upon the age . To our knowledge, no data exist to date on variations in erythropoiesis during ageing in mice. Some regulators of erythropoiesis have been characterized in recent years. One of them, named Erythroferrone (Erfe), is a hormone produced by erythroblasts that is able to regulate Hamp levels as a consequence of erythropoietic demand due to blood loss or anemia of inflammation .

Analog zu Roberts et al. (2008) wurden Interfaktor-Korrelationen zwischen EVI, IVI und KIN berechnet (Tab. 3). Zum Vergleich der Interfaktor-Korrelationen der englischen und deutschen Version wurden Fishers z Werte berechnet. Die Korrelationen zwischen KIN und den visuellen Vorstellungen (IVI und EVI) unterschieden sich nicht signifikant zwischen deutscher und englischer Version.

ST-segment monitoring, serial 12-lead ECG, and measurement of cardiac troponin levels are methods used to monitor complications. Studies evaluating the use of continuous ST-segment monitoring have shown that this method has a large sensitivity (between 55 and 100%) and specificity (between 37 and 85%) range for the detection of perioperative ischemia (intra- and postoperatively) because its effectiveness depends on the technique used and the baseline features of the population.423-426 The occurrence of postoperative ischemia detected with continuous monitoring in patients submitted to vascular surgeries has prognostic implication and is an independent predictor of long-term cardiovascular events.427,428 However, since measurement of perioperative troponin levels (a simpler test) became available, the use of automatic monitoring for diagnosis and prognosis of perioperative myocardial ischemia has been discontinued. It has not been studied further and is therefore not recommended.

Under normal conditions, elevations in systemic pressure are restricted from being transmitted to the glomerular capillaries. Indeed, the high prevalence of hypertension is the major cause of CKD. However, the incidence of CKD is relatively low in the population of hypertensive patients, except in genetic and experimental animal models of hypertension with impaired autoregulation of RBF, as well as in certain racial groups and individuals with a genetic predisposition to renal disease (Hsu et al., 2005; Kopp, 2013). Same as spontaneously hypertensive rat (SHR) and angiotensin II (Ang II)‐dependent models of hypertension, most hypertensive patients exhibit intact RBF autoregulation; they develop benign nephrosclerosis characterized by narrowing of preglomerular arterioles, which limits glomerular injury (Griffin, 2017; Hayashi et al., 1992a; Ren et al., 2010). On the other hand, RBF autoregulation is impaired and elevations in glomerular capillary pressure (Pgc) contribute to the development of proteinuria and glomerulosclerosis in Dahl Salt‐sensitive (Dahl S) (Ge et al., 2014; Ren et al., 2014; Williams, Fan, et al., 2012), Fawn‐Hooded hypertensive (FHH) (Fan, Geurts, et al., 2020; Fan, Gao, et al., 2020), Milan Normotensive (Ge et al., 2017), DOCA‐salt and reduced renal mass hypertensive rats (Griffin, 2017), as well as in some diabetic models (Hayashi et al., 1992b; Kojima et al., 2013). Moreover, servo‐control of RPP has been reported to prevent the infiltration of immune cells and the development of proteinuria and renal injury in Dahl S rats (Evans et al., 2017). Several mechanisms have been identified to explain the link between changes in RBF autoregulation and the development of proteinuria and glomerulosclerosis. Elevations in systemic pressure that increase Pgc and cause capillary distention increase GFR and the filtered load of protein by increasing both the net filtration pressure and filtration area. Abnormal renal autoregulation also fails to buffer elevations in systemic pressure from increasing Pgc. These models also exhibit glomerular hypertrophy and capillary ballooning, capillary unfolding, and microaneurysm formation secondary to mechanical distention, especially at the vascular pole (Kriz et al., 1996; Pavenstadt et al., 2003). Podocytes that support those deranged capillaries are exposed to increased mechanical stress, leading to podocyte injury and detachments from the glomerular basement membrane (GBM). As podocytes are terminally differentiated and cannot proliferate, they are no longer able to cover the increased surface area. This results in further capillary distension until the exposed GBM attaches to the glomerular parietal cells and form a tuft adhesion to Bowman's capsule. These cells proliferate along the exposed GBM, resulting in the collapse of the capillary loop and the initiation of focal glomerular sclerotic lesions (Kriz & LeHir, 2005; Pavenstadt et al., 2003).

Enerzijds gaven respondenten aan het leuk te vinden, nieuwsgierig te zijn en graag ontwikkelingen op het gebied van technologische innovaties te volgen. Net als in voorgaande vragen werden redenen voor ‘eigen belang’ en ‘belang voor anderen’ veel genoemd. ‘Om te bekijken of de nieuwe technologie iets voor mij of anderen in mijn omgeving is.’ Aan de andere kant gaven respondenten aan technologie ook moeilijk te vinden, kan deze invloed hebben op de privacy en werd niet altijd het nut ervan ingezien: ‘Ik heb geen interesse als de technologie geen noemenswaardig voordeel voor mij oplevert.’ Hiertegenover was het kunnen uitproberen van innovaties een reden om wel te participeren. Meerdere mensen geven aan dat ze graag zelf de technologie thuis testen en toepassen in hun dagelijks leven.

Our proteomic data (S2 Table) further revealed that most proteins associated with cofactor-related metabolism were downregulated at 40°C and 45°C including proteins encoded by LplJ, PncB, SufB, SufC, FolA, ApbE and IscS. However, in stark contrast, the hydroxyethylthiazole kinase ThiM, which is associated with thiamine biosynthesis, was the most highly up-regulated protein at all three elevated temperatures (log2 4.1-fold at 35°C, FDR<5%; 6.6-fold at 40°C and 7.3 at 45°C) (Fig 1, Table 1). The biologically active derivative of thiamine, thiamine diphosphate, is an important cofactor for several enzymes associated with amino acid and carbohydrate metabolism .

MLST tree showing the phylogeny of C. fetus, with original scale as reported . Reptile C. fetus represent a distinct clade harboring mat1 and galE. Diversification of C. fetus subsp. fetus (Cff) type B happened prior to the diversification of Cff type A and C. fetus subsp. venerealis (Cfv) type A strains. Cff type B strains harbor galE, mat1 and wcbK. The latter gene provides protection from acid, and this genotype is associated with animal hosts. Cfv type A represents the bovine clone harboring mat1 and galE which is also prone to HGT. Cff type A have lost mat1 but acquired glf correlating with serum resistance in Cff.

In the vast majority of the infected individuals, an effective cell-mediated immune response develops 2–8 weeks after infection that stops further multiplication of the tubercle bacilli (Figure 1). The activated T lymphocytes, macrophages, and other immune cells form granulomas that wall off the growing necrotic tissue limiting further replication and spread of the tubercle bacilli. Most of the M. tuberculosis are killed in the caseating granulomas, and disease progression is arrested. However, the pathogen is not completely eradicated in some individuals as M. tuberculosis has evolved effective strategies to evade the immune response resulting in survival and persistence of some bacilli in a nonreplicating state in the host (LTBI) [8, 21, 22]. In support of this hypothesis, M. tuberculosis has been cultured and presence of M. tuberculosis DNA has been demonstrated from lung tissues of individuals who died from other diseases and who did not exhibit any pathological sign of TB disease [23, 24]. Furthermore, a recent report showing transmission of infection from father to son in Denmark in 1961 and reactivation of latent infection in the son more than 30 years later (documented by molecular fingerprinting of their respective M. tuberculosis isolates) has indicated that the surviving bacilli may remain dormant for a long time (lasting up to a lifetime) . A subsequent defect in cell-mediated immunity may result in reactivation of dormant bacilli causing active disease many years after the infection (reactivation TB). The current understanding of the mechanisms leading to the establishment of latent infection and the transition back to active growth in reactivation of latent disease is described below.

Almost 70 years ago techniques were used by Martinovitch (7) for in vitro culture of mammalian whole ovaries. Since then, in vitro organ or fragment culture has been evaluated under different culture conditions in several species, such as mice (6, 8-11), cattle (12, 13), baboon (14), bovine (15) and human (16, 17). Eppig and O’Brien in 1996 cultured newborn mouse ovaries for 8 days and activated primordial follicles and grew them to the secondary stage. The isolated secondary follicles were cultured for 14 days, and mature and fertilizable oocytes and one living offspring were obtained (6).

The differentiation potential of DNCD3 splenic cells was also observed upon in vitro Th2 stimulation, but not CD3/CD28 or Th1 stimulation. Thus, a 3-day stimulation of negatively-sorted DNCD3 splenic cells isolated from 14 day-old NOD mice in Th2 conditioned medium led to the appearance of CD3+(4+8+) double positive T-cells, CD3+(4+8−) single positive T-cells, and few CD3+(4−8+) single positive T-cells (>1%) (Figure 5A, right panel). Aliquots of these cell cultures showed predominant IL-10 secretion after 3 days of culturing (Figure 5B). Although the IL-10 mRNA expression was absent in non-stimulated NOD DNCD3 splenic cells, its expression was detected by RT-PCR after 3 days of Th2-stimulation, which coincided with the appearance of mature CD4 T-cells in the cell cultures (Figure 5C). In contrast to Th2-stimulated cultures, there were no double positive T-cells and single positive T-cells, nor cytokine secretion detected in DNCD3 splenic cells stimulated for 3 and 5 days in Th1 conditions or CD3/CD28 Abs alone (Figure 5A left panel, and 5B). After 3 days of Th1-stimulation, the DNCD3 cell cultures showed expression of both Th1 and Th2 transcriptional factors, whereas the Th2-stimulated cultures lacked expression of Th1 transcription factors T-bet and STAT4 (Figure 5D). These results clearly indicated a biased differentiation of DNCD3 splenic cells into a TR-1 like phenotype.

CircRNAs were identified in all samples, and they were widely distributed on different chromosomes (Figure 1A and Supplementary Table S2). Of all the identified circRNAs, 78.56% were located in exons, 5.92% in introns, and 15.52% in intergene regions (Figure 1B). The size of most circRNAs ranged from 200 to 400 nt, and 82.27% of them had a predicted spliced length of <400 nt (Figure 1C). As shown in Figure 1D and Supplementary Table S3, a total of 28, 34, 42, and 47 DE-circRNAs were identified at 6 h, 12 h, 24 h, and 96 h relative to control, respectively. Of these, 59 circRNAs were up-regulated and 60 were down-regulated. Further, we performed a hierarchical cluster analysis and Venn diagram of all DE-circRNAs (Figure 1E,F). The results showed that the expression patterns of uninfected and A. salmonicida-infected samples were classified into different clusters (Figure 1E). Nevertheless, the types of DE-circRNA were changed with the increase of infection time. One circRNA (novel_circ_0005673) was shown differentially expressed at all four comparisons in the Venn diagram (Figure 1F).

Collectively, we discovered that MBD9 is required for proper H2A.Z deposition at many sites, but is not stably associated with the SWR1 complex. To investigate genetic interactions between MBD9 and ARP6, we generated arp6-1;mbd9-1 double mutant plants. We have shown that single arp6-1 and mbd9-1 mutant plants have similar phenotypic defects (S2 Fig) and that both ARP6 and MBD9 regulate H2A.Z incorporation into chromatin (Fig 2A and 2B). If these two proteins are subunits of the same complex or function exclusively in the same genetic pathway then double mutant plants should be phenotypically indistinguishable from single mutants, as previously shown for arp6;swc6 plants [18, 37]. Instead, we observed that the double mutants displayed much more severe defects (dwarf stature, deformed leaves, and drastically reduced fertility) than the individual single mutants throughout development (Fig 7). Importantly, these phenotypes in the double mutant plants reverted back to those of each single mutant by introducing either the genomic ARP6 or MBD9 constructs into the double mutants (S13 Fig), indicating that these defects were truly the result of simultaneous loss of ARP6 and MBD9 functions. To investigate whether the more severe phenotype in arp6-1;mbd9-1 plants is caused by further reduction of H2A.Z incorporation into chromatin, we performed a ChIP-qPCR experiment using H2A.Z antibody on WT, arp6-1, mbd9-1, and arp6-1;mbd9-1 plants at FLC regions 2 and 9. We found that double mutant plants had similar levels of H2A.Z depletion at FLC when compared to arp6-1 (S14 Fig). Collectively, our findings support the idea that MBD9 is not a core subunit of the SWR1 complex and suggest that this protein has additional functions outside of H2A.Z incorporation .

Caso 2: Paciente GCS, 20 anos, irmã diagnosticada com glicogenose tipo Ia, no primeiro ano de vida. Apresentou hepatomegalia (3cm abaixo do rebordo costal direito) ao nascimento, em 1998. Diante do quadro clinico e dos antecedentes familiares, iniciou-se a investigação de glicogenose. Desde o nascimento, além de hepatomegalia, apresentava alterações nas concentrações de colesterol total e triglicérides, hemoglobina glicada, ácido úrico, lactato e transaminases, fato que fortalecia a suspeita de glicogenose. Realizou a primeira biópsia aos 6 meses de idade, ainda com resultado inconclusivo, entretanto, com sinais de esteatose hepática e discreta fibrose. O diagnóstico foi praticamente confirmado aos 3 anos com nova biópsia resultando em hepatopatia crônica em cirrotização, por provável doença do acúmulo de glicogênio. Aos 4 anos, o teste enzimático foi compatível com o diagnóstico de glicogenose tipo I. Outros exames foram realizados, mas apresentaram-se negativos. A paciente manteve níveis alterados de colesterolemia e de trigliceridemia durante toda a infância e adolescência, quando em maio de 2015, aos 17 anos, iniciou estatina de alta potência em associação a ciprofibrato, 100mg/dia. Apesar das medicações, apresentava hiperlipidemia grave, com altas concentrações plasmáticas de triglicérides e colesterol total ( Tabela 1 ). Assim como ocorreu com a paciente do caso 1, as medicações foram bem toleradas e não foram observados efeitos colaterais. Também não houve manifestações de lesão renal. A paciente manteve-se eutrófica com baixa estatura durante seu desenvolvimento, com IMC normal nos dias de hoje.

Während der Schulschließungen beschäftigten sich Schüler*innen häufiger mit den Hauptfächern (Mathematik, Deutsch, Fremdsprachen) als mit den Naturwissenschaften (Accelerom AG 2020). Die für Biologie, Chemie und Physik aufgewendete Arbeitszeit hing ihrerseits von der Schulform ab und war am höchsten an Gymnasien. Unter den Fächern konnte ein Gefälle zwischen Biologie und den beiden anderen Naturwissenschaften festgestellt werden (Biologie: Gymnasium [Gym] > 60 %, Realschule [RS] > 45 % und < 50 %, Hauptschule [HS] > 30 %; Chemie: Gym > 35 % und < 40 %, RS > 20 % und < 30 %, HS > 20 %; Physik: Gym > 45 % und < 50 %, RS ca. 30 %, HS ca. 20 % [Accelerom AG 2020, S. 16]).

Liver biopsies were removed at 4 h, 24 h, 48 h, 72 h, 5 days and 7 days after partial hepatectomy and frozen at −80°C until protein extracts were prepared by homogenization in a lysis buffer (0.1 M Tris-HCl buffer, pH 7.4, supplemented with 5 mM EDTA and 5% SDS) containing complete protease inhibitors cocktail (Roche, Basel, Switzerland) and phosphatase inhibitor sodium orthovanadate (1 µM). After a 20 min centrifugation at 14 000g at 4°C, the supernatant was collected, protein concentration of the protein extracts was determined using the Bio-Rad protein assay kit (Biorad, ville, pays) and finally samples were stored at -20°C until western blot analyses. 30 µg of total liver proteins were separated by electropohoresis in a 12% sodium dodecyl sulphate (Invitrogen, Taastrup, Denmark) polyacrylamide gel. Proteins were transferred onto polyvinylamide fluoride membranes (Hybond-P, GE Healthcare, Little Chalfont, United Kingdom). Membranes were blocked for 1 h at room temperature in a blocking buffer (Tris-HCl (pH 7.6) buffer containing 150 mmol/l NaCl, 0.1% Tween-20 and 5% non-fat dry milk). The membranes were then incubated overnight at 4°C with one of the following antibodies diluted in the blocking buffer: for PCNA, mouse monoclonal antibody clone: PC10 (Signet Laboratories, Inc, Dedham, MA, USA) diluted 1∶500; for Cyclin D1, mouse monoclonal antibody diluted 1∶500 (Santa Cruz Biotechnology, Inc., Heidelberg, Germany). After rinsing in TBS-Tween, the immunoblots were incubated for 1 h at room temperature with a goat anti-rabbit or anti-mouse secondary antibody (Hercules, CA, USA), whichever appropriate, conjugated to horseradish peroxidase and diluted 1∶6000 in the blocking buffer.

In this study, we present encouraging survival and toxicity data of esophageal patients treated with definitive high-dose chemo-radiotherapy. In our cohort of 27 consecutively treated patients, estimated overall survival rates at 1, 2 and 3, years were 82%, 61% and 56%, respectively, comparing well with other recent studies. A recent meta-analysis including 6 major studies with a total of 929 patients reported 2-year overall survival rates between 35 and 58% using definitive chemo-radiotherapy . Another trial investigating 287 patients showed 2-year survival rates of 29% for patients suffering from esophageal squamous cell carcinoma and 19% for those with adenocarcinoma .

Generally, the heavy metal concentrations in the surface sediments increased with decreasing grain size (O’Reilly-Wiese et al. 1995). Nevertheless, among the heavy metals, only Cr, V, and Ni showed a significant positive correlation with the clay fraction, which might suggest lithogenic sources for those metals (Dou et al. 2013). As a major component of clayey minerals, Al was positively correlated with the clay fraction, but it showed significant positive correlations with Cr, Ni, and V as well, thus suggesting a natural origin for these heavy metals.

Salt stress is one of the major limiting factors in agricultural production worldwide, and is responsible for huge yield losses each year . High salinity causes osmotic stress, and excessive Na+ accumulation results in high levels of ROS . The application of exogenous melatonin and consequent increase in endogenous melatonin, enhanced salt stress resistance in Arabidopsis, Malus hupehensis, and maize seedlings . In cucumber (Cucumis sativus) seedlings under salt stress, melatonin treatment improved the net photosynthetic rate, photosystem II (PSII) maximum quantum efficiency (Fv/Fm), and total chlorophyll content . Melatonin-induced salinity tolerance participates in the ROS signaling route. The respiratory burst oxidase protein F (AtrbohF), an Arabidopsis rbohF mutant, reestablishes redox and ion homeostasis by regulating ROS production in salinity tolerance triggered by melatonin . ROS are most likely located upstream of NO. Therefore, these studies have shown that melatonin/NO regulate the production of ROS and oxidative defence signals in plants.

Mean workload during the LI-cycling bout was 85.0±38.0 W in the MI group and 121.0±29.0 W in the NMI group (p<0.05). There was a significant difference between groups [F(1,36.1) = 7.1, p = 0.012] and an effect of intensity for HRavg as demonstrated by the LMM [F(1,33.3) = 37.0, p<0.001]. Overall, HRavg during HI-cycling, which took into account an average of each cycle (i.e., 30s on and 30s off) throughout the 30 min duration, was lower in MI compared to NMI (140.0±18.0 and 157.0±14.0 bpm, p<0.05) [t(34) = -3.28, p = 0.002], but not during LI-cycling (133.0±18.0 and 143.0±17.0 bpm, p>0.05) [t(33) = -1.64, p>0.05]. This denotes that there is a significant difference with regard to how the level of intensity affects the two groups with the MI group experiencing less HRavg variability irrespective of intensity. When considering relative HR represented as percentage change (%Δ) from HRmax (% HRmax), significant differences were only demonstrated during an average of the 30 min cycling bout for HI (MI: 82.0±9.5 vs. NMI: 87.0±7.1%) [t(36) = -3.21, p = 0.003] (Fig 3(a) and 3(b)). In contrast, the MI group did not demonstrate a great deal of change from HI during the LI bout (MI: 78.0±19.3 vs. NMI: 79.0±23.4%) [t(36) = -0.27, p>0.05]. To further validate the findings, a paired samples t-test showed no significant difference in HRavg, however, relative change was significantly different in NMI [t(20) = 2.73, p = 0.013].

Demographic characteristics for the 70 participants in this study are listed in Table 1. The sample was predominantly middle aged, married, African American men. A weak negative correlation was found between age and percent weight change at twelve months’ post-transplantation (r = -0.32, p = 0.006). A one tailed t-test found no difference in percent weight change by sex (p = 0.23). Likewise, no difference was found for percent weight change by race (p = 0.77).

Mm strain M or Mm strain 20 fluorescently labeled with mWasabi or mCherry, respectively64,65, were microinjected into the blood island of embryos at 28 hpf as previously described66. The injection dose was 200 CFU for all experiments, except for the phagocytosis assay (500 CFU), and the RNA sequencing of infected wild types (300 CFU) and dram1 mutants (150 and 300 CFU). Embryos were manually dechorionated by tweezers before the injection. Infected embryos were imaged using a Leica MZ16FA stereo fluorescence microscope equipped with a DFC420C color camera, and the number of bacterial pixels per infected fish were obtained from the individual embryo stereo fluorescence images using previously described software67.

The mineralization of the biochar samples was carried out in a solution of HNO3 + HCl in proportions of 3:1 + 2 ml HF/sample. The element content was determined using an inductively coupled plasma-optical emission spectroscopy (ICP-OES) system (Thermo Scientific iCAP Series 6500) in accordance with Bulak et al.25. The following wavelengths (nm) were employed for the determination of elements: Al 396.152, As 189.042, Ba 493.409, Be 265.045, Ca 184.006, Cd 226.502, Co 228.616, Cr 267.716, Cu 324.754, Fe 261.187, Ga 417.206, Hg 184.950, K 766.490, Li 670.784, Mg 285.213, Mn 259.373, Mo 204.598, Na 589.592, Ni 231.604, P 178.284, Pb 220.353, S 180.731, Sc 361.384, Se 196.090, Sr 421.552, V 310.230 and Zn 206.200. The internal standard of Y was added to each sample at a concentration of 5 ppm.

Female transgenic mice models with loss of AR signaling in the brain and pituitary (NeurARKO) exhibit aberrant neuroendocrine control with females displaying elevated LH levels at diestrus, a diminished serum LH response to ovariectomy and E2 priming, and reduced kisspeptin mRNA expression in the AVPV, but elevated kisspeptin and neurokinin B mRNA expression in the arcuate nucleus at proestrus (52-55, 91, 132, 162, 255-257, 284).

Very recently a study has been reported from Sri Lanka in which the susceptibility of children with HbE β thalassemia to both P. vivax and P. falciparum malaria was assessed.34 Compared with control subjects, it appeared that those with HbE β thalassemia were more susceptible to both forms of malaria, but particularly to P. vivax. Interestingly, those who had been splenectomized appeared to be particularly susceptible, but even the malarial-antibody levels in children with intact spleens were significantly higher than those in age-matched controls. Evidence of previous vivax infection was also related to spleen size and hence to the severity of the thalassemic phenotype. Again, it is possible that the increased susceptibility to P. vivax reflects the rapidly-turning-over red cell population of children with HbE β thalassemia.

Besides all the advantages of DESs, NADESs are considered as environmentally friendly and ‘readily biodegradable’ due to the natural origin of their components , and consequently the obtained extracts can be safely used in the food, pharmaceutical and cosmetics industries . These new green solvents were firstly introduced by Choi and coworkers who defined them as the third liquid phase naturally occurring in all living organisms and cells . According to Choi , this third liquid is capable of dissolving a number of natural molecules that are poorly soluble in water and lipids such as taxol and rutin as well as proteins, explaining thus many biological phenomena such as the biosynthesis of molecules that are soluble in neither water nor lipids . The compounds found to form this liquid phase are primary metabolites like organic acids (lactic, malic, citric acids, etc.), sugars (glucose, fructose, sucrose, etc.); amino acids, choline chloride, etc. . These natural compounds play key roles in biological processes such as drought resistance, cryoprotection and defense against external attacks . Noteworthy, according to the nature of their components, NADESs can be classified into four groups: (1) derivatives of organic acids, (2) derivatives of choline chloride, (3) mixtures of sugars and (4) other combinations .

NOX4 induction appears to contribute to fibrogenesis not via oxidative stress-induced damage [26, 62, 63], but rather by chronic dysregulation of downstream signaling pathways (Figure 2). The precise oxidative target(s) of NOX4-derived ROS that culminate in myofibroblast differentiation in response to TGFβ remain(s) largely unknown. However, TGFβ1-induced NOX4-derived ROS have been shown to directly oxidatively inactivate MKP1, a dual specificity MAPK phosphatase that targets JNK and p38 . Consistently, JNK phosphorylation by NOX4-derived ROS was essential for TGFβ1-induced myofibroblast differentiation of prostatic fibroblasts and cardiomyocyte differentiation of pluripotent embryonal carcinoma cells [26, 80]. Other targets activated by NOX4-derived ROS in fibrogenic signaling cascades include ERK1/2 and Src [39, 81]. Thus, it appears that the NOX4-dependent fibrotic response can be mediated via multiple oxidative targets (Figure 2). Interestingly, activation and release of TGFβ from its latency association peptide (LAP) are also induced by oxidative modification of LAP with free radicals capable of stimulating TGFβ expression and secretion in many cell types [29, 85] (Figure 1).

Локальные породы крупного рогатого скота (КРС) могут обладать ценными генетическими вариантами для проведения селекции и создания новых пород в ответ на возникающие вызовы животноводству, включая изменение климата, появившиеся или возрождающиеся угрозы заболеваний, инновации в области диетологии и изменившиеся запросы рынка (Kantanen et al., 2015). Достижения генетики и биотехнологии дают возможность быстрого переноса уникальных генетических вариантов, возникших у местных пород КРС в процессе адаптации к локальной среде обитания, в геномы коммерческих интернациональных высокопроизводительных пород с целью сохранения их выдающихся свойств в новых условиях обитания (Stranden et al., 2019). Для повышения частот адаптивных аллелей у коммерческих пород возможно и использование методов геномной селекции. Однако для успешного применения этих технологий недостаточно знать гены, вовлеченные в адаптацию или устойчивость к болезням; надо знать, какие именно генетические варианты вносят вклад в требуемый признак. То есть необходимо изучать геномы КРС на нуклеотидном уровне и при этом учитывать исторические взаимоотношения между породами и условия их формирования для того, чтобы отличить функционально важные генетические варианты от результатов генетического дрейфа и прохождения «бутылочного горлышка».

Twelve chicks were taken randomly from each treatment at the end of the trial, two birds per replicate, weighed individually and slaughtered. At 54 °C for 2 min, the chicks were scalded and then de-feathered, and eventually, their heads were cut. Breast muscles and abdominal fat were immediately separated from the hot carcass. The internal organs from the beginning of the esophagus to the end of the outlet were separated in a detailed anatomical fashion . Using a sensitive balance of 0.1 g, the intestines were cleaned and weighed, and the data were expressed as a percentage of carcass weight. The dressing percentage was calculated by dividing the clean carcass weight by the living body weight. The breast muscle, thigh muscle, abdominal fat, gizzard, liver, heart and small intestine weights were estimated as a percentage of carcass weight.

Thirteen concatenated mitochondrial protein genes from C. sokolovi and other 11 rodent mitogenomes were utilized to perform phylogenetic analysis through Bayesian inference (BI), and BEAST V1.6.1 was used for this process (Drummond et al. 2012). Eothenomys melanogaster and Eothenomys miletus were selected as outgroups. The details of BI analysis methods were consistent with those in previous study (Chen et al. 2020), and the best-fit GTR + I + G model of DNA substitution was selected using Akaike Information Criterion (AIC) test in JModelTest 2 (Darriba et al. 2012). As indicated by the phylogenetic tree (Figure 1), C. sokolovi is sister to C. griseus and the genus Cricetulus is polyphyletic. Cricetulus migratorius does not cluster with other Cricetulus but stands as a sister branch to a well-supported grouping of Cricetus + Allocricetulus. Besides, C. kamensis clusters together with Phodopus roborovskii and Phodopus sungorus, suggesting that there is a close phylogenetic relationship between them. Nowadays, the classification of subfamily Cricetinae is still controversial. As a result, in order to gain some better insights into the phylogenetic relationship within Cricetinae, more complete mitochondrial genome sequences are needed.

Schoener’s D was calculated as a measure of niche overlap. This revealed a high overlap of the niches of P. bulbosa and its definitive host Erignathus barbatus (D = 0.543), but a much lower overlap (D = 0.018) with the host Pusa hispida (Table S3, Fig. 2).Figure 2Parasite and definitive host niches in niche space.

I appreciate the further specification of the authors decision for using the Modified Downs and Black quality assessment to the manuscript. However, I do not feel the authors have sufficiently explained why they have neglected an a-priori established part of their protocol and chosen to use a different method. This undermines the credibility of the manuscript as one of the major strengths of a systematic review lies in the protocol that is established a-priori. As such, I would again ask the authors to explain in their response to reviewers letter why they made this decision.

L'hémophilie reste un problème de santé dans les pays en voie de développement, d'un coté par la gravité de certains tableaux hémorragiques qui peuvent entrainer le décès ou par le biais des complications articulaires entravant le pronostic fonctionnel. Et d'un autre coté par le cout élevé des facteurs. L'instauration récente d'un programme de prise en charge des hémophiles avec mise en disponibilité gratuite des facteurs et création des centres de référence équipés en personnel: kinésithérapeute, infirmière et médecin référent a fortement soulagé le personnel soignant ainsi que les familles des patients.

A capacidade funcional foi avaliada antes, 45 dias após o início do exercício e ao final do experimento. Os ratos foram submetidos a 5 min/dia de adaptação ao ambiente de teste por uma semana antes da avaliação. Cada animal foi testado individualmente. O teste consistiu em um aquecimento inicial de 5 minutos a 5 m/min em uma esteira. Os ratos foram então submetidos a exercícios a 8 m/min, seguidos de incrementos de 3 m/min a cada 3 minutos, até a exaustão. A exaustão foi determinada quando o animal se recusou a correr mesmo após a estimulação elétrica ou foi incapaz de coordenar os passos.15,16 A velocidade máxima de corrida foi registrada e a distância total, calculada. Os resultados do teste de exercício de treinamento de 45 dias foram usados para ajustar a intensidade do exercício.

Bereits in frühen CKD-Stadien lässt sich eine Verminderung der Protein- und Energieaufnahme nachweisen; Appetitlosigkeit besteht schließlich bei etwa einem Drittel aller Dialysepatienten [18, 19]. Daneben bestehen bei Patienten mit CKD eine Vielzahl von Diätvorschriften, welche die Aufrechterhaltung einer ausreichenden Proteinzufuhr erschweren.

Finally, it is important to note that the areas identified in this study overlap with regions thought to be involved in descending pain modulation (Millan, 2002). Furthermore, it is interesting that there appears to be a relationship between the cardiovascular and descending pain modulation systems, as the greater the magnitude of cardiovascular response during the cold pressor test, the greater an individual's endogenous analgesic ability (Chalaye, Devoize, Lafrenaye, Dallel, & Marchand, 2013). Our findings that MSNA‐related regions overlap with those involved in endogenous analgesia further support the idea that the two systems are intertwined.

We used secondary progression (SP) as the outcome variable. The SP is responsible for nearly all severe neurological disabilities in patients with MS.20 The term is used according to a consensus definition.24 SP is required to be sustained during one year of observation. EDSS is often used as an endpoint. However, it is variable, also when expressed as 3 months sustained EDSS,25 and secondary progression was considered a reliable measure of an irreversible course, particularly in studies over a long span of time.26 Information on onset of secondary progression was re-considered if the patient reached an EDSS of 4 or 6. The EDSS 4 is often reached simultaneously with the transition to the SP.

Table 3 provides estimates of the association between smoking status and health provider communication and students’ beliefs about smoking for asthmatic students (adjusted for model-specific confounders detailed in Table footnotes). Among students with asthma, smoking status was associated with health professionals asking students about their smoking. Specifically, asthmatics who were asked if they smoked had 2.46 higher odds of smoking than those who were not asked if they smoked (95 % CI: 1.04–5.81). Asthmatic students who thought it was safe to smoke for only 1–2 years had 3.97 times higher odds of smoking than those who did not believe it was safe (95 % CI 1.57–10.06).Table 3Associations between provider-related communication, smoking beliefs and smoking: Virginia asthmatic high-school students (n = 255)a QuestionSmoked in past 30 daysAdjusted OR (95 % CI)Weighted percentDuring the past 12 months, did any doctor, dentist, nurse, or other health professional ask you if you smoke?

By employing H2 instead of tertiary amines as the sacrificial agent, a viable CO2 reduction approach with Pt/C and ReI(L)(CO)3-MHPW12VI O40 (L = 5,6-(15-crown-5)-1,10-phenanthroline) as synergistic catalysts was developed. The grafting of ReI(L)(CO)3 complexes onto POMs was achieved via the complexation of crown ether moiety on L with the sodium cation binding two PW12O40 moieties (Figure 4) . H2 was oxidized with the facilitation of Pt(0) on the Pt/C surface to afford two protons. In the following step, protons and electrons retained by Pt were simultaneously transferred onto ReI(L)(CO)3(CH3CN)-MHPW12VI O40 (MHPW12VI O40 + 2H+ + 2e− → MH3 PW2V W10VI O40) (Scheme 1). ReI(L)(CO)3-MH3PW2V W10VI O40 possessed the photoreductive activity for converting CO2 to CO, because its transition to excited CO2-reduction active state was allowed by absorbing visible light. CO were almost exclusively produced with turnover of 22.6% and 1.1% quantum yield. Besides CO, only trace CH4 but no further CO reduction products (e.g., CH3OH, HCHO, and HCOOH) was detected on GC-MS after 14 h irradiation.

The addition of EcSSB dramatically altered the progressions of the MMR components on the mismatched DNA (Fig. 3). When visualized by smTIRF numerous events were detected where an EcMutL sliding clamp co-localized with EcUvrD near the ssDNA break. However, these complexes displayed very little if any detectable movement (compare Fig. 1c with Fig. 3a and Supplementary Fig. 2e). In contrast, numerous unwinding and rezipping events were detected on single molecules by smFS (Fig. 3b). The frequency of DNA molecules undergoing unwinding/rezipping was relatively constant over a wide-range of EcSSB concentrations (Fig. 3c, top). We parsed the molecules observed at each EcSSB concentration into those that had undergone unwinding followed by rezipping back to fully duplex DNA (restored) and those that remained unwound after the 25 min observation period (unwound; Fig. 3c, bottom). The majority of mismatched DNA molecules at zero or sub-saturating concentrations of EcSSB (<10 nM) displayed very long ssDNA tracts, remained unwound, and occasionally terminated in a DSB similar to the smTIRF studies in the absence of EcSSB (Fig. 3c). However, at saturating EcSSB concentrations (>200 nM) the majority of the mismatched DNA molecules were rezipped to restore their original length (Fig. 3b, c).Fig. 3EcSSB modulates EcUvrD unwinding. a Representative kymographs showing the formation of a AF555-EcMutL(green)-AF647–EcUvrD(Red) complex (merged, yellow) in the presence of ATP (1 mM), EcMutS (10 nM, unlabeled) and EcSSB (200 nM, unlabeled).

Notre étude note une prédominance féminine avec un sex-ratio femme/homme de 3,17. Ce résultat est proche de ceux des séries africaines et mondiales [4, 5]. La moyenne d’âge rejoint également celle des autres études [2–4]: elle se situe dans la 4ème décennie, La moyenne d’âge (M.A) en fonction du sexe dans les différentes études est représentée dans le Tableau 1. Dans notre période d’étude, la prévalence des carcinomes thyroïdiens représentait 12,57%, Rego-Iraeta et al rapportent un pourcentage similaire, alors que les donnés africaines [2, 4], rapportent une prévalence de 6,33% et 7,68% respectivement. La taille moyenne tumorale de 16 mm, reflète la sensibilité diagnostic des outils échographique et anatomopathologique de cette série, chose rapportée également par Xiang . Les données de la littérature présente une nette prédominance des carcinomes thyroïdiens différenciés de souche folliculaire (papillaires et vésiculaires), leur prévalence dans notre étude est de 94%, elle est similaire à celle des études mondiales de Rego-Iraeta (89,7%), Mehry (94%), et de Xiang (96,6%). Par contre, le profil épidémiologique de chacun des deux types histologiques diffère d'une série à l'autre: les cancers vésiculaires étaient moins fréquents dans notre étude (4%) par rapport à la plupart des fréquences rapportées dans la littérature. Leur prévalence était de 45% dans deux séries africaines [2, 4], par contre elle était dans les séries mondiales de Sassolas , Fauconnier , Rego-Iraeta , et de Brownlie , de l'ordre de 5.9%, 11%, 13.7%, et de 19% respectivement. En effet, la carence en iode, sévissant en Afrique, est incriminée dans la survenue de ce type de cancer ; Les carcinomes papillaires, quant à eux, avaient une fréquence de 90% dans notre étude, la plaçant au cotés de séries mondiales récentes de Xiang (92,8%) et de Sassolas (86.5%), qui ont toutes comme point commun une part importante des microcarcinomes (38% dans notre étude, 35,7% chez Xiang et 36% chez Sassolas), révélés par l'examen anatomopathologique à l'occasion de thyroïdectomies pour des pathologies bénignes. Par ailleurs, la prévalence des carcinomes papillaires dans la série africaine de Rakotoarisoa sont de 50%. Pratiquement tous nos malades ont bénéfices d'une thyroïdectomie totale en un ou deux temps. Les recommandations de «l'American Thyroid Association» (ATA) sont en faveur de cette pratique chirurgicale, non pas seulement pour les tumeurs supérieures à 1 cm, mais aussi pour celles inférieures à 1 cm également, compte-tenu de la présence de certains facteurs associés, pouvant favoriser leurs récidives; parmi eux: l’âge > 45 ans, les microcarcinomes plurifocaux (16% dans notre étude).

ΔFZD1–10 HEK293 cells (34) were transiently transfected in suspension using Lipofectamine® 2000 (Thermo Fisher Scientific). A total of 4 × 105 cells were transfected in 1 ml with 10 ng of Nluc-tagged receptor plasmid DNA or 100 ng of HiBiT-tagged receptor plasmid DNA and 990 or 900 ng of pcDNA plasmid DNA. The cells (100 µl) were seeded onto a poly-d-lysine-coated black 96-well cell culture plate with a solid flat bottom (Greiner BioOne). Twenty-four hours posttransfection, the cells were washed once with 200 µl of Hanks' balanced salt solution (HBSS; HyClone). In the kinetics experiments, the cells were preincubated with 50 µl of the Nluc substrate vivazine (1:50 dilution; Promega) in a complete, non-phenol red DMEM (HyClone) supplemented with 10 mm HEPES for 1 h at 37 °C without CO2. Subsequently, 50 µl of eGFP-Wnt-3a conditioned medium or control medium supplemented with 10 mm HEPES was added, and the BRET signal was measured every 60 s for 180 min at 37 °C (181 measurements, no CO2). In the saturation-binding experiments, the cells were incubated with different concentrations of eGFP-Wnt-3a conditioned medium (90 µl) supplemented with 10 mm HEPES for 120 min at 37 °C with no CO2. Next, for the Nluc-tagged constructs, 10 µl of the Nluc substrate furimazine was added (1:100 dilution; Promega), and for the HiBiT-tagged constructs, 90 μl of a mix of furimazine (1:100 dilution; Promega) and LgBiT (1:200 dilution; Promega) was added. The cells were incubated for another 10 min prior to the BRET measurements. The BRET ratio was determined as the ratio of light emitted by eGFP (energy acceptor) and light emitted by Nluc/HiBiT-tagged receptors (energy donors). The BRET acceptor (bandpass filter, 535–30 nm) and BRET donor (bandpass filter, 475–30 nm) emission signals were measured using a CLARIOstar microplate reader (BMG). eGFP fluorescence was measured prior to reading BRET (excitation, 470–15 nm; emission, 515–20 nm). Data were analyzed using GraphPad Prism 6.

The 50 L culture of strain SY1965 was centrifuged to yield filtrate and mycelia. The mycelia were extracted with MeOH three times to give mycelium extract. The filtrate was absorbed onto a HP-20 column eluting with water and then MeOH to obtain crude filtrate extract. The mycelium and filtrate extracts were combined and then partitioned with EtOAc three times to afford a crude extract (2 g). This crude extract (2 g) was subjected to a column of ODS eluting successively with 30% MeOH, 50% MeOH, 70% MeOH, and 100% MeOH to give three fractions (Frs. A–C) based on the results of TLC and HPLC analyses. Fr. A was fractionated by Sephadex LH-20 using 40% MeOH to give subfractions A1–A3. Fr. A1 was separated by using CXTH LC-3000 preparative HPLC (column: Fuji-C18 CT-30, 280 × 30 mm, 10 µm; flow rate: 10 mL/min; UV detection: 210 nm) with linear gradient from 30% to 60% MeOH in 40 min, isocratic elution with 60% MeOH from 40.01 to 50 min to afford a mixture of 6 and 7 (5 mg, tR 30 min), 8 (3.3 mg, tR 32 min), a mixture of 2 and 3 (2.2 mg, tR 39 min), 1 (1.8 mg, tR 45 min). The mixture of 6 and 7 was separated by Agilent 1260 HPLC purification (column: Agilent Zorbax SB-C18, 250 × 9.2 mm, 5 µm; mobile phase: MeCN/H2O, 21/79; flow rate: 1 mL/min; UV detection: 210 nm) to give 7 (3.4 mg, tR 17 min) and 6 (3.0 mg, tR 23 min). The mixture of 2 and 3 was separated on a chiral HPLC column (CHIRALCEL® OJ-RH, 150 × 4.6 mm, 5 μm; mobile phase: MeCN/H2O, 11/89; flow rate: 0.4 mL/min; UV detection: 210 nm) to give 2 (0.7 mg, tR 24 min) and 3 (0.6 mg, tR 26 min). Compounds 9 (4.0 mg, tR 28 min), 10 (3.3 mg, tR 34 min) and 12 (4.0 mg, tR 40 min) were obtained from Fr. A3 by preparative HPLC using the same CT-30 column with linear gradient from 30% to 100% MeOH in 46 min. Purification of Fr. A2 and B by the same SB-C18 column and flow rate with UV detection of 210 nm gave a mixture of 4 and 5 (2 mg, tR 13.5 min, MeCN/H2O, 50/50) from Fr. A2, 11 (1.0 mg, tR 23.5 min, MeCN/H2O, 49/51) from Fr. B, respectively. The mixture of 4 and 5 was further separated by the same chiral HPLC column (mobile phase: MeCN/H2O, 15/85; flow rate: 0.5 mL/min; UV detection: 210 nm) to give 5 (0.7 mg, tR 17 min) and 4 (0.7 mg, tR 18.5 min).

Au sujet de la chaleur, seulement 6% des postes de travail mesurés respectent les normes en matière de chaleur pour un travail lourd. Les températures effectives psychométriques mesurées vont de 24,5 à 35,5 °C. Une exposition prolongée affecte la santé des travailleurs par la déshydratation, les crampe musculaires, l'insolation, le coup de chaleur, l'épuisement à la chaleur voire même la mort [17, 34–39]. Il convient cependant de noter que la lutte contre les températures élevées et l'humidité restent difficiles car ces dernières étant nécessaires pour les opérations. En Tunisie, Amri Ch. et al évoquent aussi des plaintes liées à la chaleur enregistrées dans les ateliers de finissage . Ce qui soutient nos résultats. Il en est de même de l'étude faites en Inde par Srivastava A et al. qui met en évidence les températures élevées sur le lieu de travail. Cette étude appelle cependant à adapter le standard international dans les pays tropicaux et subtropicaux. On a observé que les gens sont en général plus tolérants à l´exposition de chaleur comparativement aux personnes dans les régions plus froides [38, 39]. Les valeurs limites d'exposition pour les pays tropicaux devraient reposer sur les conditions climatiques locales. En outre, dans des pays en développement la pauvreté pousse les populations à travailler dans des conditions insalubres pour besoin d'emploi et de subsistance . Par contre, l'enquête SUMER 2003, a montré que 21% des travailleurs sont confronté à des nuisances thermiques. Mais, sur les 5,4% exposés aux températures supérieures à 24°C, 21% se trouvent dans le secteur textile .

Chen et al. (2015) implemented LSTM on China stock market. They collected data from stocks and divided percentage returns of prices into seven groups: (−∞, −1.5], (−1.5, −0.5], (−0.5, 0.4], (0.4, 1.4], (1.4, 2.5], (2.5, 4.3], (4.3, ∞). The main aim of the research was tosuccessfully predict a proper group for the next day return. In addition to returns data, they also used 10 different features: open, low, high, close prices and volume for a given stock, and the same five features for Shanghai Securities Composite Index. Model specification used in this research: 30 days sequence length, ‘RMSprop’ optimizer and learning rate 0.001. The best results measured by accuracy of predicted return group were given by model using all ten features achieving 27.2% accuracy, which is twice as much as randomly picked groups. M’ng et al. (2016) also explored trading with the FFN (Feedforward neural network) supported by the set of technical indicators (seven in total, downloaded from the Bloomberg website) as input variables. Their target was to predict close price changes of Kuala Lumpur Composite Index using historical data ranging from 2008 to 2014.

In order to measure the health status of certain countries in an objective, comprehensive yet concise, and universally applicable manner, the 2018 Global Reference List of 100 Core Health Indicators published by WHO were utilized. From which six health indicators were selected. Although the selection of the indicators has been put into careful consideration, it can be argued that the selection is subject to personal preference. This is especially the case for the selection of indicators for infectious disease. In this paper, we selected TB and HIV prevalence rate as indicators for morbidity of infectious diseases, although prevalence of other infectious diseases such as Hepatitis B, congenital syphilis, or malaria could also be used. The reason for choosing TB and HIV over other infectious diseases is their relatively higher rate of prevalence, worldwide occurrence (e.g., unlike malaria, which has higher prevalence rate in tropical regions, the distribution of TB occurrence is less dependent on geographic location), and higher reception for general public (e.g., HIV is probably more familiar for general public than congenital syphilis).

Results are presented using two analytical strategies in the main text. Both strategies are highlighted in Fig. 2. The “most current” approach is used to select the data shown in Fig. 3. The “month stratified” approach is used for Figs. 3 and 4. In the “most current” approach, the most recent 4 weeks of model dates are used for each extrapolation length. Therefore, for 1-week errors, models from October were used, whereas, for 12-week errors, models from July and August were used. This allows for the assessment of the most recent evidence possible for each set of errors displayed. Four-week periods are used to ensure that the results are not unduly biased by featuring only a small number of runs for each model.

Oxidative stress was found to be a primary cause in the pathogenesis of hypertension due to endothelial cell dysfunction . Growing evidences suggest a crosslink between NO deficiency and development of oxidative stress in the onset and progression of vascular impairments . During the normal physiology, NO reduces superoxide anion (O2−) production through a sustained suppression of NADPH oxidase, the major source of vascular oxygen radicals .

The outcome phase was characterized by the “Feedback Related Negativity” (FRN), which was superimposed on a large positive deflection (referred to as P3) and more pronounced in loss trials (Figure 4). It was seen in both groups (ANOVA, Factor OUTCOME; F(1,18) = 17.4; p<.001, η2 = .49), and there was a tendency for the FRN to be more negative for loss trials in “active” blocks (OUTCOME x BLOCK; F(1,18) = 3.25; p<.088, η2 = .15, no further significant main effects or interactions).

The transcriptional co-activator Yes-associated protein (YAP), identified as a target of the Hippo pathway has recently been identified as an additional regulatory component of canonical Wnt/β-catenin signalling11, 12. In the cytoplasm, YAP interacts with β-catenin directly and restricts nuclear translocation of β-catenin13. Moreover, YAP is essential for β-TrCP recruitment to the destruction complex and facilitates β-catenin degradation14, indicating that YAP is pivotal for the ubiquitination and proteasomal degradation of β-catenin.

Adhesive-removal somatosensory test: Two small adhesive-backed paper dots (1 cm2) were used as bilateral tactile stimuli occupying the distal–radial region on the wrist of each forelimb. The rat was then returned to its home-cage. The time to remove each stimulus was recorded for 3 trials per day. Individual trials were separated by at least 5 mins. The animals had been pre-trained for 3 days before surgery.

Cytosolic glutathione S-transferases (GSTs) are encoded by a superfamily of genes grouped intoα, μ, π, σ, θ, ζ, and ω classes by primary amino acid sequence , . The enzymes, which can exist as homo- or heterodimers of subunit polypeptides, catalyze reactions involving the conjugation of reduced glutathione (GSH) to electrophilic substrates. By targeting electrophiles generated by cytochrome P450s for conjugation with GSH, GSTs contribute to coordinated drug and xenobiotic metabolism, promoting the ultimate elimination of potential toxins by the ATP-dependent glutathione S-conjugate export pump . The π-class GST, a homodimeric enzyme which was first described as a placental isoform, has since been found in many different tissues and is now known to be the most abundant of the GSTs . The amino acid sequence of π-class GST subunit polypeptides is remarkably conserved across species, perhaps because the enzymes have been implicated in a broad array of vital cell and tissue functions, including xenobiotic metabolism, cell signaling, mutagen/carcinogen defense, and antineoplastic drug resistance .

In this section we formally define each of the two distances. For two FCGR probability matrices (pij) and (p′ij) we define dij=|pij−p′ij| The distance between the two probability matrices denoted by DPM=∑i=12k∑j=12kdij For two genomes, we calculate 100 centroids cij = (xij, yij) and c′ij=(x′ij,y′ij) respectively for 1 ≤ i, j ≤ 10. Then we found Euclidean distance between them dij=(xij−x′ij)2+(yij−y′ij)2. Then calculated the centroid distance between two genomes denoted by Dcd=∑i=110∑j=110dij.

Three main pathways of ceramide generation have been described: de novo biosynthesis from serine and palmitoyl-coenzyme A, the sphingomyelinase pathway, and the salvage pathway that re-creates ceramide from sphingosine (Fig. 1):Serine palmitoyltransferase (SPT) catalyzes the first, rate-limiting step of sphingolipid biosynthesis. SPT product is then converted into sphinganine (dihydrosphingosine) which is used by CerS to generate dihydroceramide , which recently emerges as a signaling molecule on its own [23, 24]. Dihydroceramide is then converted to ceramide by dihydroceramide desaturase.Ceramides can give rise to sphingomyelin produced by sphingomyelin synthase (SGMS or SMS). The opposite reaction catalyzed by sphingomyelinases (SMases or SMPDs), termed the sphingomyelinase pathway is a major ceramide source .Ceramide can be further converted by ceramidases into sphingosine which modulates the cell death machinery and nitric oxide (NO) signaling [28, 29]. Thanks to their relatively broad substrate specificity, ceramide synthases (there are CerS1 to 6, also named longevity assurance gene homologs Lass1 to 6) can re-synthesize ceramide from sphingosine (the salvage pathway). The presence of six tightly regulated and interdependent ceramide synthases plus their splice variants assures the necessary variation in synthesized ceramides . CerSs are known to undergo phosphorylation, acetylation, N-glycosylation, and ubiquitination, implying tight (but still poorly understood) regulation [30, 31].Fig. 1Sphingolipid metabolism and the three pathways of ceramide biosynthesis. The scheme shows only selected reactions and enzymes, plus their feedback regulation by S1P and C1P.

La pathologie hydatique est très fréquente au Maroc et au pourtour méditerranéen . La localisation cérébrale est rare, ne représente que 2% environ de toutes les localisations hydatiques de l´organisme et touche surtout l'enfant et l´adolescent . Les signes cliniques sont ceux d'un processus intracrânien, la TDM souvent suffisante pour poser le diagnostic et le traitement reste chirurgical.

Deficiency of DNA repair drives cells to undergo apoptosis, which led us to study the putative effect of cetuximab and/or oxaliplatin exposure on this specific cell death process. In HCT-8 cells exposed to oxaliplatin/cetuximab, morphologic changes associated with apoptosis (DNA condensation and fragmentation) occurred 24 h earlier than in cells exposed to oxaliplatin alone and could play a role in the enhanced antiproliferative effects that we observed previously (Chaney et al, 2005). In HCT-8 cells, oxaliplatin exposure promoted survival through AKT activation; cetuximab exposure concomitant with oxaliplatin inhibited this regulation and induced restoration of apoptosis through the inhibition of oxaliplatin-induced AKT activation. On the other hand, when the non-responsive HCT-116 cells were exposed to oxaliplatin either alone or combined with cetuximab, we observed similar nucleic morphologic changes. At the same time, no effect on AKT phosphorylation was observed in this cell line. Because activation of survival through the PI3K/AKT pathway is one mechanism by which cells can resist to cytotoxic drug exposure (Kim et al, 2005), such data suggest that the inhibition of AKT activation and related effects on apoptosis could be part of the HCT-8 synergistic response to the oxaliplatin/cetuximab combination. On the other hand, in HCT-116, a K-Ras mutated cell line, EGF-R inhibition had no effect either on the MAPK pathway (data not shown) or on AKT phosphorylation. This lack of effect could explain the lack of efficacy of cetuximab in K-Ras-mutated colorectal cancer (Benvenuti et al, 2007).

I dati attuali indicano che i pazienti sopravvissuti a SARS-Cov mostrano, entro 3 mesi–15 anni di follow-up, ipocortisolismo (40%), sindrome da fatica cronica (20–40%) e artrite da osteonecrosi avascolare subcondrale (10%) , supportando l’idea che l’infezione da SARS-Cov-2 possa indurre una risposta immuno-neuroendocrina (corticosurrenalica e simpato-linfoide) deficitaria. Le basi storiche di questo tipo di risposta sono rintracciabili nell’ipotesi di Galeno (II sec. d.C.) sulla necessità dei nervi periferici per la funzione dei linfonodi, da lui indicati come “ghiandole del corpo” (De Usu Partium XVI, 269). Nel 1565, poi, l’anatomico e clinico piemontese Leonardo Botallo osservò che le condizioni di stress psichico (emozioni eccessive) producevano “febbri”, introducendo l’idea che la mente fosse coinvolta nel controllo del corpo alle malattie, ipotesi confermata tra il 1888 e il 1926 con la scoperta dell’innervazione linfonodale e del condizionamento pavloviano delle reazioni immunitarie . Infine, nel 1984 il fisiologo americano J. Edwin Blalock propose il concetto di interazione bidirezionale tra sistema immune, centri neurali e funzione endocrina . Oggi, dopo 1800 anni di evidenze, il paradigma della risposta immuno-neuroendocrina trova una sorprendente e, forse, inattesa conferma anche negli effetti devastanti della più recente pandemia da Coronavirus dove, appunto, l’uso dei corticosteroidi si è riaffermato come un presidio terapeutico importante.

Sequencing reads were first trimmed for sequencing adaptor and then for quality at Phred score of Q20. Only paired end reads longer than 50 nucleotides were kept using the SolexaQA package . Reads were mapped against the mouse genome version 10 using TopHat and Bowtie 2 . Read count were summarized at the transcript level using RefSeq annotation from the mapping using bed tools and in-house PERL script. The differential expression analysis was performed using the EdgeR Bioconductor package . The library size was corrected to take into account the sequencing depth . Transcripts with less than 1 count per million (CPM) per replicate were removed. Read counts were then normalized using the trimmed mean of M-value (TMM) approach. Biological coefficient of variation was estimated using the triplicates. Differential expression (DE) analysis using a quantile adjusted conditional maximum likelihood (qCML) approach was conducted. The p-values were then adjusted using the Benjamini-Hochberg procedure with a threshold of 5% false discovery rate (FDR).

Em estudos recentes, a identificação de áreas de alto risco, por meio de combinação de diferentes técnicas de análise espacial, possibilitou melhor precisão na análise. Além disso, contribuiu para o delineamento de áreas prioritárias para intervenções específicas a serem adotadas pelos programas de controle, bem como avaliação dos impactos das ações estratégicas. 2 , 14 Estudo com diferentes abordagens espaciais foi realizado em área considerada de alto risco no Brasil, envolvendo quatro estados brasileiros, e foi suficientemente válido e de suma importância no delineamento de vários clusters de municípios com elevada magnitude, transmissão ativa e diagnóstico tardio de hanseníase. 1 A abordagem espacial já foi aplicada para direcionar a busca ativa de casos com estratégias eficazes e de baixo custo para controlar a hanseníase. 26

In this framework, Europe was first inhabited by Paleolithic and later Mesolithic hunter-gatherer groups. Then, starting about 7000 BCE, farming peoples arrived from the Middle East as part of a Neolithic transition7, spreading through Anatolia and the Balkans8,9 while progressively admixing with local hunter-gatherers10. Major movements from the Eurasian Steppe, beginning about 3000 BCE, resulted in further admixture throughout Europe11–14. These events are typically modeled in terms of three ancestry components: western hunter gatherers (“WHG”), early European farmers (“EEF”), and Steppe pastoralists (“Steppe”). Within this broad framework, the island of Sardinia is thought to have received a high level of EEF ancestry early on and then remained mostly isolated from the subsequent admixture occurring on mainland Europe1,2. However, this specific model for Sardinian population history has not been tested with genome-wide aDNA data from the island.

Our finding of impaired baseline IAc and of low interoceptive sensibility assessed by the MAIA questionnaire in sDID patients might be interpreted as fitting with the theory of experiential avoidance (Hayes et al., 2004). This theory implies that it is difficult for people high in experiential avoidance to ‘remain in contact with particular private experiences (e.g., bodily sensations, emotions, […])’ (Hayes et al., 1996, p. 1154). Psychometrically, our sDID patient sample exhibited pronounced experiential avoidance in the Acceptance and Action Questionnaire (Table 2). However, it is not possible to conclude from our data whether impaired IAc is owed to avoidance, to inability, or both. Further studies including the subjective aversiveness of the heartbeat detection tasks could shed more light on this question. Considering data by Dyer et al. (2015) assuming the own body is a trigger in post-traumatic conditions, impaired IAc in our patients might be due to avoiding getting in touch with the trauma-associated own body.

Selection for egg quality is an important component of the breeding strategies of companies that market egg-laying type hens. Indeed, consumers demand high quality products with strong eggshell, while reducing cost, guaranteeing eggs devoided of microbial contaminants, and improving the acceptability of rearing systems . Most selection strategies to improve egg quality has focused on the shell’s physical properties (and its ability to resist shocks), stability of egg weight, egg-white quality, and yolk percentage. Egg-white quality essentially refers to albumen height that reflects freshness, and its ability to prevent microbial growth and survival that may be associated with toxi-infection risks for consumers (Salmonellosis). Recently, some authors reported differences in albumen height/pH in various selected lines and corroborated that selection on specific traits has changed the proportion of the yolk, albumen, and shell while increasing albumen height. The moderately high variability in weights of egg yolk and albumen was also observed when comparing selected and traditional lines . Egg white is a very unfavorable medium for bacteria, due to its high viscosity, its pH becoming progressively alkaline upon egg storage (7.8 to 9.5), and to the presence of a myriad of antimicrobial molecules (See Section 3.1). In fact, the antibacterial potential of egg white was demonstrated to be moderately inheritable . Concerning egg proteins and peptides, some difference in relative abundance of certain molecules have been reported in brown versus white eggs or in different lines, but the major egg proteins remain basically unchanged .

Um quarto dos adolescentes que referiram consumo de álcool no último mês no presente estudo experimentou pela primeira vez antes dos 12 anos de idade, sendo essa proporção maior no sexo masculino. Outros estudos, nacionais e internacionais, também relatam início precoce na experimentação de bebidas alcoólicas 3 , 7 , 10 , 12 . Esse dado é preocupante se considerarmos que o consumo de bebidas alcoólicas só está legalmente autorizado no Brasil em indivíduos com 18 anos ou mais, e que a iniciação precoce tem sido associada com maior risco de lesões não intencionais, acidentes de carro, comportamento de risco sexual, uso de tabaco e de drogas ilícitas, além de prejuízo cognitivo na vida adulta 9 , 11 .

Mentre nei monti, sono selve e boschi, gli alberi, sterpi, erbe e cose simili, ritengono qualche parte dell’acqua, e qualche parte ne è succhiata dalla terra, e nelle selve per lo più il suolo è disuguale, e fa seni e concavità, le quali pure l’acqua ritengono. Il rimedio dunque sarebbe il non permettere il continuarsi dell’estirpare le selve e i boschi, ma concedere solo il legname, senza svellere le radici.

Most survey questions pertaining to ANC, SBA, and IPTp only covered the respondent’s most recent birth. As this restriction disproportionately excludes older children from high parity mothers, we restricted the age range for children aged 0–12 months to avoid bias. Additionally, the Uganda National Panel Survey (UNPS) only ascertained pentavalent and measles immunization status for children aged 0–24 months, and weight measurements were taken for children aged 6–59 months . In order to maximize data inclusion while keeping age groups consistent across surveys, we used the UNPS age groups for all survey data extraction pertaining to these indicators. Immunization coverage estimates were obtained using vaccine cards whenever they were available; in cases where cards were not present at the time of survey, maternal recall was used to supplement immunization data.

As there are currently no approved drugs for COVID-19, we used a list of drugs currently in clinical trials for preliminary validation (Table S3). A list of 322 drugs in clinical trials for COVID-19 (as of 1 January 2021) was curated from ClinicalTrials.gov as a surrogate for effective drugs (see the Materials and Methods section). The drug rankings provided by the network-based approach were able to predict the drugs in clinical trials with an AUC of 0.64 (Fig 3A).

The AFM measurements and imaging were carried out using the Nanoscope V Multimode scanning probe microscope. All images were obtained using the tapping mode with a single LTSP silicon probe (force constant of 48 N/m, Digital Instruments). The resonance frequency of this cantilever was approximately 167 kHz, while the scan angle was maintained at 0°. The images were captured in the retrace direction with a scan rate of 0.5 Hz. The image resolution is 256 samples /line. After obtaining the measurements, the “planefit” and “flatting” functions were applied to each image of the sample. The dimensions of the particles were determined by an analysis of the phase and height of the extracted AFM images that were collected simultaneously using the Nanoscope Software Version 7.3.

Chromocenters in the rod cells were scored at two age points, P30 and P53. For each age, three mice were used, two Mecp2-/y and one Mecp2 +/y littermate. From each animal 25-μm-thick cryosections were prepared from the three retina areas: central, mid, and peripheral. To distinguish between individual nuclei in tightly packed rod perikarya, the nuclear envelope of rod cells was stained with anti-lamin B1 antibodies (sc-6217). Between 600 and 800 rod cell nuclei were scored in stacks collected from each retina area. Descriptive statistics was performed using SigmaStat software.

The results of this study also indicated that pre-heating of the bulk-fill composite resins used did not have a statistically significant effect on their cytotoxicity, and the study was unable to reject the first hypothesis. Thus, the pre-heating of the composite resins did not cause adverse reactions, and the cytocompatibility of the components released from the composite resin was not affected. This result was consistent with those of a study by Deb et al.11 In their reports, the pre-heating of composite resins did not significantly influence their cytotoxicity. However, the study by Knežević et al13 suggested that cell viability was affected by the pre-heating temperature.

Azaacenes (N-heteroacenes) are derivatives of acenes in which a fraction of carbon atoms are substituted by more electronegative nitrogen atoms. This substitution induces significant changes in their electronic, redox and spectroscopic properties. Quantum-chemical calculations, and especially those based on Density Functional Theory (DFT), constitute a powerful tool for the elucidation of the effect of N/C ratio and the N atoms distribution mode on the electronic and redox properties of azaacenes. This approach allows for the determination of their HOMO and LUMO levels as well as their ionization potentials (IPs) and electron affinities (EAs) in vacuum or in a given solvent. The latter can be confronted with experiments consisting of chronovoltamperometric determination of IP and EA. Even though the experimental values may sometimes differ from the calculated ones, especially in the case of EA, the observed trends usually remain the same.

For data preprocessing, all transcriptomic datasets were analyzed by FastQC v0.11.6 (Brown et al., 2017), with the default parameters for a statistical analysis of quality. Trimmomatic v0.36 (Bolger et al., 2014) was used to filter the adapters and low-quality sequences using the following parameters: LEADING:3, TRAILING:3, SLIDINGWINDOWS 4:15, MINLEN:50, and TOPPHRED64. For data mapping, clean data from Trimmomatic were mapped to the respective reference genomes (Zhao et al., 2018) using HISAT2 v2.1.0 (Kim et al., 2015) software, with the following modifications from the default parameters: –min-intronlen 20, –max-intronlen 4000, and –rna-strandness RF. All datasets from HISAT2 were reserved (Supplementary Table S2) for transcript assembly. During transcript assembly, the fragments per kilobase of transcript per million mapped reads (FPKM) values were obtained using Cufflinks v2.2.1 (Trapnell et al., 2012), with the default parameters, except for an additional parameter,-u. Differentially expressed genes were assessed using Cuffdiff v2.2.1 (Trapnell et al., 2012) using the default parameters. Additionally, the 3σ criterion formula of “threshold = average (5% value) + 3∗ SD” (You et al., 2017) was used to calculate the FPKM thresholds in each experimental group (Supplementary Figure S1). The genes with FPKM values below the threshold in each sample were removed because of insignificant correlation coefficients. The FPKM threshold values were 0.27 and 0.18 for C. simplicifolius and D. jenkinsiana, respectively, as shown in Supplementary Figure S1.

Between the two healthy seed samples (CAP01 and CAP03), no significant statistical differences were found regarding morphological, nutritional, phenological and agronomic results. Both samples have been selected for commercial purposes, mainly due to high production and protein content.

From the eight primer sets developed, only one (AT430F (5′-GCTAAGTTAACTGAAGATCCACCAT-3′) and AT622R (5′-TAGTTCCACTAATACTAAGAGCCCC-3′)) proved to be reliable for SHB detection and identification, because all tested SHB individuals yielded amplification products of the expected size 193 bp (lanes 1–20, Figure 1A,B) and no amplification products were obtained for any of the non-target species: A. concolor, A. flavicollis, and A. inconspicua (lanes 1’–3’, Figure 1A,B). The successful amplification of products from all of these samples with the universal primers LCO1490/HCO2198 confirmed the presence of amplifiable DNA and the absence of Taq DNA polymerase inhibitors thereby validate the negative results (data not shown). PCR with the specific primer pair AT430F/AT622R and series of diluted crude DNA from a single SHB specimen were used to test the sensitivity. The primer pair yielded positive results for 0.1 ng/µL of the diluted SHB DNA (lane 8, Figure 1C).

In contrast, a more recent article has identified positive effects of neurexin 1α in the presence of α 2δ-1 (but not α 2δ-3) on pre-synaptic Ca 2+ transients in hippocampal neurons and in parallel on Ca V2.1 calcium currents 12. Importantly, very carefully done experiments, designed to detect an interaction of neurexin 1α with α 2δ-1 or α 2δ-3, failed to find a specific association between the two proteins, as every protein tested (α-neurexin, neuroligin, and two forms of cadherin) was pulled down with α 2δ-1 (and also α 2δ-3 co-immunoprecipitated with neurexin 1α). The authors concluded that neurexin 1α does not form stable complexes with α 2δ subunits but nevertheless influences their function. Their results also provide a warning that α 2δ proteins may be rather prone to co-immunoprecipitation artefacts.

An advanced comprehensive analysis has been applied to investigate the various types of oxidative modifications of proteins in legume nodules (Matamoros et al., 2018). In this method, a carbonyl moiety on a protein, which is formed due to oxidation or RCS addition (Møller et al., 2007), is labeled with a biotin probe. The labeled protein fragments are collected by avidin affinity chromatography and then analyzed with LC-ESI-Orbitrap-MS, which allows identification of the modified peptide, the modified amino acid residue, and the type of carbonylation. In the root nodules, 12 types of carbonylations affecting six amino acid residues were identified in 238 proteins. Interestingly, Lys was the most commonly carbonylated amino acid and accounted for 58% of all modifications, followed by His, Cys, Arg, Thr, and Pro (Matamoros et al., 2018). It is also possible to investigate the difference of the extent of modification extent on the same target protein in samples treated differently. This method has a great potential to investigate the RCS target proteins that are involved in plant responses to oxidative stimuli.

Raw scores offer superior resolution across the entire spectrum, and preserve relative differences between scores that may otherwise be rounded away in the scaled scores (only six significant digits are retained in the scaled scores). For example, the bottom 90% (∼7.7 billion) of all GRCh37/hg19 reference SNVs (∼8.6 billion) are compressed into scaled CADD units of 0 to 10, while the next 9% (top 10% to top 1%, spanning ∼774 million SNVs) occupy CADD-10 to CADD-20, etc. As a result, many variants that have substantively different raw scores may have very similar, or even the same, scaled scores; and scaled scores accurately resolve differences between variants’ scores only at the extreme top end. Thus, when comparing distributions of scores between groups of variants (e.g. variants seen in cases versus variants seen in controls), raw scores should be used. However, when discovering causal variants or fine-mapping variants within associated loci, scaled scores are advantageous as they allow the user a direct interpretation in terms of the estimated pathogenicity relative to all possible SNVs in the reference genome.

Fig 12 shows the MLEM reconstructed images from the original and denoised sinograms. It can be seen that at the high count Frame 14, all denoising methods can effectively reduce image noise without compromising the main texture features, while KGF denoising attains the best visual effect. However, at the low and middle count Frames 4 and 9, only KGF can achieve these and the effect of other methods are rather limited.

Devant toute intoxication à un insecticide pyréthrinoïde, il faut vérifier sa composition exacte à la recherche d'un solvant tel que l'éthylène glycol. En effet, le solvant peut avoir un potentiel toxique plus grave que l'insecticide lui-même et sa présence pourrait avoir d'importantes implications diagnostiques et thérapeutiques. Par ailleurs, la législation doit imposer aux industriels d'indiquer sur l'étiquetage des insecticides tous les composants potentiellement dangereux pour l'homme. Enfin, les solvants dangereux ne devraient pas être utilisés dans la fabrication de ces insecticides.

It has also become apparent that increased glycolytic metabolism during T cell activation does not come at the expense of OXPHOS, which is also upregulated in these cells in order to meet the bioenergetic demands that accompany their activation. In addition to supporting ATP production in activated T cells, mitochondrial metabolism also yields ROS important for activating specific cell signaling pathways that lead to clonal expansion. 236 With glucose serving as the substrate for aerobic glycolysis in activated T lymphocytes, OXPHOS is instead driven primarily by metabolism of glutamine in these cells, 230 , 237 , 238 as discussed in more detail below. Finally, though the transition from effector to memory T cells is associated with a shift from aerobic glycolysis to FAO‐based metabolism, glucose is still necessary to support the de novo synthesis of lipids for subsequent oxidation. 239 , 240 In memory cells, FAO enhances spare respiratory capacity, supporting mitochondrial function that not only promotes the long‐term survival of these cells but that is also key to the rapid induction and maintenance of both aerobic glycolysis and OXPHOS, which are again upregulated during recall responses. 241 , 242

Em resumo, o diagnóstico correto da síndrome de Takotsubo muitas vezes permanece indefinido. Por outro lado, dados recentes mostraram que a ressonância magnética tem um papel promissor na síndrome de Takotsubo e pode representar, no futuro, a base para o diagnóstico diferencial.6 As síndromes coronarianas agudas representam hoje um grande e importante grupo de doenças cardíacas, cada uma com características e tratamento específicos. A síndrome de Takotsubo, pelo contrário, ainda carece de uma identidade definitiva. Ela é uma doença específica e independente ou uma apresentação peculiar de uma síndrome coronariana aguda? Como na versão hebraica da história de Jonas na Bíblia, a Takotsubo deve nadar mais rápido, ficar mais forte e crescer; caso contrário, será engolida pelo peixe gigante.

Nesse cenário, buscam-se opções para resolver os problemas de saúde de pacientes graves, por meio de recursos efetivos para prestar um cuidado com qualidade. Nesse contexto, a telemedicina é uma alternativa viável para oferecer uma resolução eficiente desses problemas. A Organização Mundial da Saúde (OMS) define a telemedicina como “a oferta de serviços relacionados à saúde, onde a distância é um fator crucial”.(3) A telemedicina tem o potencial para melhorar a qualidade do cuidado, ao permitir que os médicos em um “centro de controle” monitorem, atendam e realizem alguns procedimentos em pacientes que estão em diferentes lugares. A experiência da telemedicina em outras especialidades médicas aplica-se integralmente ao campo da medicina de emergência.(4,5)

As estimated in China and other countries, overall age-standardized H1N1pdm cumulative incidence varied significantly by age with the highest in children 5–19 and 0–4 years old . This age distribution was different from the seasonal influenza which mostly infected the elderly population . In the present study, we evaluated neutralization antibodies against H1N1pdm as well as recent circulating seasonal H1N1 viruses in serum samples collected before and after the pandemic. The samples were further resorted by birth year to estimate the age-specific H1N1pdm infection. In addition, we examined H1N1pdm and seasonal H1N1 specific memory B and IFN-γ+ T cells frequencies using ELISpot assay in healthy individuals, whose blood had been collected in 2006, and aimed to evaluate the potential connections of pre-existing cellular immunities and age-dependent H1N1pdm influenza infections.

Ist gegenseitiges Verständnis für Vereinbarkeitsherausforderungen gegeben, sind auch Störungen und Situationen, in denen klare Grenzziehungen nicht gelingen, kein Problem, wie eine Interviewte schildert:Mein Chef hat auch Kinder, auch ein kleines Kind. Meine Kollegin hat drei Kinder. Das Verständnis ist da, ne, dass halt vielleicht auch mal ein Kind dann reinplappert, wenn man gerade in einer Audio ist oder so, es geht halt nicht anders. Ist dann einfach so. Aber das ist in Ordnung. Zumindest bei uns, ne?
