Cost-effectiveness is investigated through calculation of the costs of TAU as compared to costs of MULTI + . This social cost benefit analysis uses data from patient files to determine the costs of care used in the different conditions (TAU vs. MULTI +), and medication costs based on DDDs. Additionally, for the subgroup that answered questions regarding quality of life, we investigate impact on quality of life as opposed to costs. The total costs per measuring moment per patient is used as an outcome measure and expressed in euros.

Influenza A infection causes substantial morbidity and mortality each year . Periodically, novel human strains emerge, spread rapidly, and cause increased incidence of infection, as was the case with the novel 2009 strain of H1N1 pandemic influenza (H1N1pdm) . However, because many influenza infections are either asymptomatic or cause only mild symptoms, it is difficult to measure infection, rather than clinical disease, across a population . With only clinical data, establishing robust rates of severe disease per infection is difficult. Also, it is not possible to establish traditional risk factors for infection. Hence, it is challenging to generate evidence-based advice for individuals and policy makers about the value of interventions designed to reduce the chance of infection, such as vaccination, social distancing, and other nonpharmaceutical interventions.

Quantitative chromatin immunoprecipitation (qChIP) was performed following IP with the indicated antibodies. qPCR was carried out using primers for human CDK1 that span the region encompassing the putative κB-site (sense GGGTTCTCACATTGCCCTGT, anti-sense TCCAAAGTGCAACACTGTGC). The change in DNA enrichment for each IP condition was determined relative to input DNA. To control for non-specific binding, anti-p50 data was subtracted from anti-H1 results (anti-IgG showed no binding) as previously described12.

For the GEE models, Base State 1 was the reference state for determining the difference of utility across base states, while Base State 2 was the reference state for understanding AE disutilities. The transformed utility values were used as the response variable and AEs or base states as a predictor variable. An additional GEE model was run to test and adjust for potential explanatory sample variables: participant’s age, gender, and EQ-5D index score. The goodness of fit for both AE GEE models (unadjusted and adjusted) was examined by using the quasilikelihood under the independence model criterion (QIC) statistics. All data processing and analyses were performed with SAS® software for Windows Version 9.4 (SAS Institute, Inc., Cary, NC, USA).

We hypothesised apriori that non-compliance with water advice would be higher for the 'Do Not Drink' phase compared to the 'Boil Water' one. In addition, we predicted that demographic factors (such as age, gender, home ownership and employment), prior beliefs/experiences, use of information sources, and practical issues (e.g. loss of electricity) could have had an effect on participants' perceptions and behaviours; however, as no formal hypotheses were defined apriori, statistical outcomes should be interpreted solely as indicators of the potential strength of association. Quantitative analysis is mainly descriptive. Inferential analysis was carried out using chi-square, ANOVA, and for repeated measures generalised estimating equations (with and without prior factor analysis). For analyses with multiple outcome variables, initial analysis was done using multivariate ANOVA with all possible outcome and predictor variables. For all analyses with multiple predictor variables, only those variables that were significant at the p < 0.2 level in single predictor models were included in the multiple predictor models. The least significant variable was then removed from the model until all predictor variables were significant at the p < 0.2 level. The value of the model in predicting each dependent variable was then derived from the tests of between subjects effects in the corrected model. Throughout, the level of significance was set at 5% and only responses with at least 10 responses deferred from the median response were included as dependent variables.

Anders verhalte es sich bei den Sprechhandlungen. Mit ihnen wird kein feststehender egoistischer Zweck verfolgt, sondern Verständigung angestrebt. Das bedeutet nicht, dass Sprechhandlungen nach Habermas zweckfrei wären – wobei dieses Missverständnis sehr naheliegend ist, da er Verständigungsrationalität von Zweckrationalität scharf abgrenzt. Das wesentliche am verständigungsorientierten Sprechen ist vielmehr, dass die Ziele vorbehaltlos und einvernehmlich festgelegt werden: Die Beteiligten sind „nicht primär am eigenen Erfolg orientiert“ (ebd.), sondern erzielen durch das wechselseitige Erheben und Prüfen von Geltungsansprüchen einen begründeten Konsens. Bei der Koordinierung ihrer Willen unterwerfen sie sich also dem zwanglosen Zwang des besseren Arguments, d.h. sie passen nicht das Argument der individuellen Interessenlage an, sondern lassen sich von interpersonell als gültig anerkannten Gründen leiten. Damit ist zugleich klar, dass Sprechhandlungen nicht nur in Kooperationszusammenhänge eingelassen sein können, sondern immer schon eine dreifache Relation voraussetzen: Sprecher und Hörer verständigen sich über etwas in der Welt.

Учитывая, что пациентов в ФГБУ НМИЦ Эндокринологии Минздрава России направляли врачи из разных, не связанных между собой медицинских центров, из различных районов Москвы и Московской области, предполагается, что выборка репрезентативна для общей популяции мужчин с гиперандрогенией. Однако, все же возможно искажение репрезентативности в отношении российской популяции по уровню образования, образу жизни и доходов пациентов.

Die Aufrechterhaltung der häuslichen Pflege wurde insbesondere durch Wegfall oder Reduzierung professioneller und informeller Unterstützungsangebote erschwert. Ein Drittel der Pflegenden der vorliegenden Studie musste die Pflege mit deutlich weniger Hilfe durch Familie oder Freunde bewältigen. Dabei zeigen Studien, dass besonders informelle Unterstützung eine der wichtigsten Ressourcen pflegender Angehöriger bei der Bewältigung von Pflege ist .

Un homme âgé de 65ans, sans antécédents pathologiques notables admis pour une fièvre chronique évoluant depuis 01mois associée à une toux sèche, l'examen physique trouvait un patient conscient, fébrile à 38.3 C, stable sur le plan hémodynamique, un souffle d'insuffisance mitrale avec des œdèmes des membres inférieurs blancs mous prenant le godet arrivant jusqu'au mi-jambe, une échocardiographie transthoracique ((ETT) couplée à une échocardiographie trans-oesophagienne) étaient réalisées montrant deux végétations mobiles sur les sigmoïdes aortiques (Figure 1), une végétation mobile sur une grande valve mitrale perforée avec insuffisance mitrale importante (Figure 2, Figure 3, Figure 4), une fuite aortique modéré, un bon ventricule gauche et une hypertension pulmonaire modérée. Le bilan inflammatoire était perturbé, les hémocultures ont isolé à deux séries un enterocoque. Le bilan d'extension basé essentiellement sur une tomodensitométrie (TDM) cérébral et thoraco-abdomino-pelvien ayant montré un anévrysme mycotique cérébral (Figure 5), deux foyers d'infarcissement splénique et un petit foyer d'infarcissement rénale gauche (Figure 6). Le fond d'œil a objectivé la présence d'une tache de Roth. Le diagnostic d'une endocardite sur double valvulopathie mitro-aortique multi-compliquée a été retenu, le traitement initial était basé sur une bi-antibiothérapie initialement avec bonne évolution clinico-biologique. Une ETT de contrôle a objectivé la persistance d'une végétation de 0,5cm sur une fuite aortique modérée et la persistance d'une végétation de 0,4 × 0,9cm sur la grande valve mitrale qui est perforée avec IM importante, le patient a été traité ensuite pour double remplacement valvulaire mitro-aortique avec bonne évolution post-opératoire initiale et disparition de l'anévrisme cérébral.

Der gewählte Ansatz zur Feststellung von Erfolg fundiert auf der Betrachtung zweier Merkmale. Zuerst, ob die von den Plattformen an sich selbst gesetzten Ziele erreicht wurden. Die zweite Ausprägung von Erfolg beruht auf den positiven Entwicklungen, die innerhalb von Projekten, welche während der Coronakrise gestartet wurden, sichtbar geworden sind. Dabei wurde beispielsweise in Betracht gezogen, ob eine außerordentliche Aufmerksamkeit in der Presse aufgetreten ist oder ein starkes Wachstum anhand von Nutzerzahlen festgestellt werden konnte.

To study the clinicopathological significance of SAM68 in MIBC, we examined the SAM68 protein expression levels in 129 paraffin-embedded, archived MIBC, from radical cystectomy, with long term follow-up data. The IHC results are summarized in Table 1. SAM68 protein was detected in 123 out of 129 (95.3%) human MIBC samples, in which 70(54.3%) showed high expression of SAM68 protein and 59(45.7%) showed low expression of SAM68 protein (Figure 3A). For the localization of SAM68 protein, there were three types of expression pattern, including nucleus expression, cytoplasm expression and nucleus-cytoplasm co-expression (Figure 3B). 43 cases (35.0%) had SAM68 expression in nucleus, 23 cases (17.8%) in cytoplasm and 57 cases (46.3%) had SAM68 expressed in both nucleus and cytoplasm.Figure 3Typical images showed the expression level and localization of SAM68 protein as examined by immunohistochemistry (IHC).

Duurzame verandering kan alleen wanneer we als volwassenen het goede voorbeeld geven én onze sociale en fysieke omgeving veranderen. Professionals in de gezondheidszorg kunnen individueel adviezen geven, maar voor maatschappelijke impact is veel meer nodig. We willen de focus leggen op positieve gezondheid en, zeker als het om kinderen gaat, gezond gedrag benadrukken, zoals buiten zijn, buiten spelen, bewegen en veel afwisseling bij beeldschermgebruik.

Per la NAFLD non esistono attualmente terapie specifiche. È noto dalla letteratura che il cambiamento dello stile di vita, focalizzato su calo ponderale, moderazione nell’assunzione di alcolici ed esercizio fisico, determinino un’importante riduzione dell’entità della steatosi epatica e dell’insulino-resistenza . Tali misure di cambiamento dello stile di vita sono peraltro condivise per la prevenzione e il trattamento di altre patologie metaboliche, come il diabete mellito.

Crystallization trials for all the constructs were carried out at 15mg/ml with 5-fold molar excess of the ligand (SAM, SAH and SFG). Initial screens were set up with Oryx Nano (Douglas Instruments) at 20°C using commercially available screens in a sitting drop format with 0.3μl of protein mixed with equal volume of reservoir solution. Among the three fusion constructs, only the fusion construct with a PAA linker produced initial hits. Initial crystals were observed in solutions containing 15% Reagent Alcohol, 0.2M Lithium Sulfate and 0.1M Sodium Citrate pH 5.5 in 2 days. The crystals were further optimized by varying both concentration of the Reagent Alcohol and also the pH of the buffer in hanging drop format using 1μl protein with 1μl reservoir. The crystals were cryoprotected in a step-wise manner with reservoir solutions containing 5–30% Glycerol and ash-cooled in liquid nitrogen. X-ray diffraction data were collected at the NSLS-II 17-ID-1 and 17-ID-2 beamlines at the Brookhaven National Laboratory (BNL) under cryogenic conditions.

Immunohistochemistry and image analysis were used to determine TLR4, and HBD2 expression using rabbit polyclonal antibodies (Santa Cruz Biotechnology, Santa Cruz, CA) in central (internal perimeter >6 mm) and distal (internal perimeter < or = 6 mm) airways . LSAB2 Dako kit (Code N° K0674) (Dako, Glostrup, Denmark) and Fuchsin Substrate-Chromogen System Dako were used for the staining. Rabbit negative control immunoglobulins (Dako) were used for negative controls. The immunoreactivity was evaluated blindly by 2 independent investigators using a Leica (Wetzlar, Germany) microscope ×400 magnification. The length of the basement membrane was evaluated using a Quantimet 500 MC software (Leica) for Image Analysis. Results were expressed as the number of positive epithelial cells/mm basement membrane as reported in a similar COPD study .

La medicina nuclear utiliza radionúclidos con fines diagnósticos y terapéuticos para detectar y tratar tumores y enfermedades benignas. En el contexto de la oncología moderna, esta especialidad involucra el uso de elementos radiactivos para evaluar las funciones corporales, determinar el diagnóstico y el tratamiento, así como la conjunción de los dos (“teragnóstica”) 1. Hay una gran variedad de radiofármacos utilizados en la medicina nuclear, pero en la mayoría de los procedimientos se recurre al tecnecio 99m (Tc99m) y al yodo radioactivo (I131) 2.

The spectrum (in arbitrary units) kprotein(λ) can be obtained by measuring the absorption coefficient αprotein(λ) experimentally (as shown in the inset of Fig. 2a) and by using the relation \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$k_{{\mathrm{protein}}}\left( \lambda \right) = \frac{\lambda }{{4\pi }}\alpha _{{\mathrm{protein}}}\left( \lambda \right)$$\end{document}kproteinλ=λ4παproteinλ. The absolute spectrum can be calibrated by using the value calculated at the wavelength λ = 680 nm. Having estimated the extinction coefficient, i.e., the imaginary part of the refractive index, we calculate its real part nprotein by using the well-known Kramers–Kronig relations and by assuming the short wavelength value nprotein(λ→0) = nlipid. We show a complete spectrum for the complex refractive index nprotein in Fig. S2 for case B. The real part nprotein(λ) shows only a small deviation (~5%) with respect to the short wavelength value nprotein(λ→0). Lower chlorophyll concentrations will result in an even lower deviation; therefore, in the following, we simply assume nprotein = nlipid = 1.55 across the whole spectrum of interest. This value is also in agreement with previous literature37.

No deaths occurred during the dosing period. The following changes in 1 male animal of the 40 mg/kg group were observed in the body weight, hematology, blood biochemistry, urinary biomarker, body temperature, organ weight, necropsy, and histopathology: decreased body weight, decreased RET, increased BUN, decreased CRE, Na, and Cl, increased calbindin, decreased body temperature, dilatation of distal tubules, regeneration of distal tubular epithelium, granular cast of collecting tubules, and foreign body granuloma of interstitium in the kidney (Figure 9(Fig. 9)). The plasma concentrations of OPC-163493 were elevated in a dose-related manner in both sexes, and no remarkable gender differences were observed. The NOAEL was estimated to be 20 mg/kg/day for males and 40 mg/kg/day for females. At the NOAEL, the plasma Cmax and AUC24h of OPC-163493 at Week 13 were respectively 13.81 µg/mL and 91.44 µg·h/mL in males and 12.62 µg/mL and 96.10 µg·h/mL in females. The results of observations, measurements, and examinations are shown in Supplementary Table 12.

The limitations of this study were the lack of complete data in the registries, a problem identified throughout the country and Latin America. Neither were other variables from the cancer care line included that could improve the diagnosis of the situation, such as oncological surgeries performed or palliative treatment. However, no official records to carry out these evaluations are available.

En tercer lugar, la integración del PAI en el sistema de salud y la construcción de la sostenibilidad de sus avances para hacer frente a los desafíos actuales y pendientes son condiciones que no se producen en el vacío. Por el contrario, la efectividad de tales estrategias depende de la presencia, el fortalecimiento y la transformación de estructuras organizativas e institucionales que faciliten la participación de los actores con capacidad técnica y política para garantizar sus procesos de implementación. De esta forma, se ponderan los procesos políticos que legitiman una agenda de inclusión del PAI en la Estrategia de salud universal y, por lo tanto, como parte del fortalecimiento de los sistemas de salud.

Increased expression of acetyl CoA C-acyltranferase (spot 19), 2,4-dienoyl-CoA reductase (spot 20), acyl CoA dehydrogenase (spot 26), fatty acid desaturase type I (spot 27) and triacylglycerol lipase superfamily (spot 31) involved in beta oxidation of fatty acid metabolism, under autotrophic condition was observed. Acetyl CoA C-acyltransferase participates in the final step of β oxidation of fatty acid to form acetyl CoA molecule and an acyl CoA molecule. 2,4 dienoyl-CoA reductase is an accessory enzyme that participates in the beta oxidation and metabolism of polyunsaturated fatty enoyl-CoA esters. Specifically, it catalyzes the reduction of 2,4 dienoyl-CoA thioesters of varying length by NADPH cofactor to 3-trans-enoyl-CoA of equivalent length. 2,4 Dienoyl-CoA reductase (DECR) from Escherichia Coli shares very similar kinetic properties to that of eukaryotes, but differs significantly in both structure and mechanism. In addition to NADPH, E. Coli DECR requires a set of FAD, FMN and iron-sulfur cluster molecules to complete the electron transfer . Acyl-CoA dehydrogenase catalyzes the initial step in each cycle of fatty acid β-oxidation. Their action results in the introduction of trans double-bond between C2 and C3 of the acyl-CoA thioester substrate . For activity of this enzyme, FAD is a required as a co-factor to bind its appropriate substrate. Fatty acid desaturases type1 are enzymes that catalyze the insertion of a double bond at the delta position of fatty acid, in autotrophic growth condition of bacteria. Thus, it can be inferred that more β oxidation of fatty acid occurs under autotrophic condition in comparison to heterotrophic condition. In this experiment, various fatty acid biosynthesizing proteins involved in the lipid production were over-expressed in heterotrophic condition and they included 3-oxoacyl-(acyl-carrier protein) synthase III, enoyl-(acyl-carrier- protein) reductase and fatty acid synthesis plsx protein. 3-Oxoacyl-[acyl carrier protein (ACP)] synthase III catalyses the first condensation step within the FAS II pathway, using acetyl-CoA as the primer and malonyl-ACP as the acceptor. The oxoacyl-ACP formed by this reaction subsequently enters the elongation cycle, where the acyl chain is progressively lengthened by the combined activities of several enzymes. 3-Oxoacyl-(acyl-carrier-protein) reductase participates in fatty acid biosynthesis and polyunsaturated fatty acid biosynthesis. The plsX gene is part of the bacterial fab gene cluster which encodes several key fatty acid biosynthetic enzymes. The plsX gene encodes a poorly understood enzyme of phospholipid metabolism , . In our study, enoyl-CoA hydratase/isomerase was found in both autotrophic and heterotrophic medium and they were not found to express differentially. It was observed that in lipid production, heterotrophic growth of bacteria is more significant than autotrophic.

Известно, что GAGA-фактор участвует в регуляции транскрипции большой группы генов с различными клеточными функциями (van Steensel et al., 2003; Omelina et al., 2011). В базе данных Flybase аннотированы гены, участвующие в широком спектре процессов, связанных с клеточной гибелью (Gene Ontology terms: apoptotic process, autophagic cell death, salivary gland cell autophagic death). Всего в этой группе представлено около 400 генов, приблизительно 180 из них, согласно профилям связывания GAF из проекта mоdeNCODE, содержат в промоторных районах сайты связывания GAF и являются, таким образом, потенциальными мишенями этого белка. Наибольший интерес представляют присутствующие в этом списке консервативные гены аутофагии – Atg2, Atg4, Atg5, Atg7, Atg8, Atg9, Atg16, Atg17, Atg18. Большинство этих генов кодируют белки, непосредственно участвующие в формировании и созревании аутофагосом, а Atg17 – белок, контролирующий инициацию аутофагии (Noda, Inagaki, 2015). Также потенциальным геном-мишенью GAF является Tor, кодирующий киназу, вовлеченную в регуляцию аутофагии. Инактивация TOR-киназы в ответ на недостаток питательных веществ или ростовых факторов стимулирует аутофагию (Levine, Klionsky, 2004; Das et al., 2012). Если предположить, что GAF регулирует Tor и группу генов Atg в сперматогенезе, то его недостаток может вызвать нарушение экспрессии этих генов и привести к массовой и неуправляемой аутофагии. При этом по отношению к Atg-генам GAF должен выполнять функцию негативной регуляции, а по отношению к Tor – позитивной.

During each time step we challenge all susceptible hosts with possible infections by allowing every susceptible individual to contact one randomly selected partner. If this partner is infected, it will transmit its virus with a probability or depending on the infection state of the infecting host (see Table 2). Properties of the virus, i.e. its evasion strategies, are not changed upon transmission.

We also conducted light intensity (P light) dependent J–V measurements of the devices to examine the effect of MX 2 interlayer on charge recombination. The dependence of V oc on P light is plotted according to the relation: V oc∝nkT/q ln(P light), where n, k, T, and q are ideality factor, Boltzmann constant, temperature in K, and elementary charge, respectively. The value n reflects the carrier traps assisted recombination in the active layer or at interfaces at open circuit condition.[ 44 , 45 ] As shown in Figure 3e, the control device shows a slope of V oc versus semilogarithmic P light of 1.74 kT q−1, which is only slightly reduced to 1.66 kT q−1 for an MoS2 incorporated device and 1.60 kT q−1 for a WS2 incorporated device. Notably, the lowest slope of 1.47 kT q−1 is observed for a WSe2 incorporated device, indicating that the trap‐assisted recombination losses are greatly suppressed than in other devices. The less trap induced recombination in a WSe2 incorporated device benefits from its proper energy level alignment with NiOx and FASnI3, which promotes hole transfer from perovskite to HTL.

Several terms are used to refer to the process leading from the production of research-based knowledge to its use by practitioners and decision makers: knowledge translation, knowledge mobilization, knowledge implementation, knowledge transfer and exchange, etc. (Graham et al. 2006; McKibbon et al. 2010). It follows that each of the terms employed to describe the phenomenon that leads produced research results into practice is defined in many different ways throughout the scientific literature. Although a multitude of definitions exist, there has yet to be a consensus identifying the most appropriate one (Pentland et al. 2011). The term knowledge transfer is, however, the most commonly employed around the world (Graham et al. 2006) and is the one used throughout this article. The Fonds de recherche du Québec—Société et culture defines knowledge transfer as “all efforts made to ensure research activities and results are known and recognized… so they can be put to use by practice settings, decision-makers and the greater public, whether the process is interactive or not” (authors’ translation) (FRQ-SC 2011, p. 9).

It has been demonstrated experimentally that the captured PPG signal exhibits sensitivity in its response to the subject’s muscular tension level and limb motion. Devices such as an accelerometer, a respiration monitor belt and a blood pressure monitor, have been deployed in conjunction with the custom designed PPG sensor system for investigation of the effects of external physiological parameters on the PPG signals in the context of autonomic nervous system and local blood pressure. The results have shown that the baseline of PPG signal is affected by acceleration particularly in the vertical direction as opposed to acceleration in the horizontal plane for the system under test. Experimental results from a total of 23 subjects demonstrated that PPG signals during motion events are influenced by the variation of local blood pressure at the point of measurement which is in turn induced from: (1) the vertical height difference between the measuring site and the reference level (the heart level); and (2) the autonomic nervous system. The results of a statistical analysis conducted on 18 subjects (9 male and 9 female) have shown that the dependency of the Baseline (BL) and Amplitude (AM) values of the PPG signal are only weakly dependent on the VHD. It is envisaged that the results of this investigation can be used as a basis for optimizing measurements of PPG based sensors in terms of potential removal of motion artefact.

Currently, multimeric enzymes, involving dehydrogenases, oxidases, or catalases are one of the most widely used groups of enzymes. These are enzymes characterized by bigger molecular weight and bigger structure, as they are built of subunits. However, multimeric enzymes, due to the consistency of subunits are characterized by low operational stability and are very prone to inactivation due to subunits dissociation under harsh process conditions . Further, besides enzyme inactivation, subunits dissociation could also lead to products contamination. The most effective approach to improve the stability and reusability of both monomeric and multimeric biomolecules is multipoint or multi-subunit immobilization. It is based on a multipoint attachment of the biomolecule or its subunits to the surface of support materials that is rich by the highly active chemical groups capable of covalent binding of the enzyme . In this approach, the enzyme gained a high rigidity and remained almost unaltered during conformational rearrangements caused by heat, organic solvents, or pH . It should be added that multipoint enzyme immobilization, besides stable enzyme binding to the support, reduces also subunits dissociation in consequence prolonging enzyme activity . Further, multipoint immobilization is considered a technique that greatly stabilizes enzymes from different catalytic groups and is more effective than a simple one-point immobilization. Immobilization could also enhance enzyme activity, as well as its specificity and selectivity leading to wider practical application possibilities . Finally, it should be noted that enzyme purification by immobilization could be also achieved, leading to a significant reduction in operational costs . It should be added that immobilization usually creates diffusional limitations in the transport of substrate and products leading to a decrease in reaction efficiency. However, properly performed and controlled enzyme immobilization might reduce the creation of diffusional limitations. Further, the formation of diffusional limitation, observed usually in the case of porous support materials, might have a positive effect on enzyme activity, for instance in a situation where the substrate of the reaction acts as an enzyme inactivation agent .

All 13 patients underwent FED-TF surgery for L5–S1 disc herniations without foraminoplasty, and the surgical feasibility rate was 100%. None of the surgeries resulted in neurological complications. On clinical assessment, the mean JOA score significantly improved from 16.0 ± 4.5 preoperatively to 23.8 ± 4.2 immediately postoperatively and 25.2 ± 2.7 a month after surgery (p < 0.01, p < 0.01, respectively) (Figure 3). The mean VAS for low back pain significantly decreased from 60.0 ± 26.8 preoperatively to 17.0 ± 20.0 immediately postoperatively and 19.0 ± 15.1 a month after surgery (p = 0.01, p < 0.01, respectively). The mean preoperative VAS for leg pain was 71.3, which significantly improved to 26.3 ± 25.9 immediately after surgery and 20.0 ± 13.1 a month after surgery (p < 0.01, p = 0.03, respectively) (Figure 3).

Dass beide Anknüpfungen auch in Deutschland möglich sind, zeigen – wieder ohne Anspruch auf Vollständigkeit – Initiativen wie die Nationale Forschungsdateninfrastruktur für personenbezogene Gesundheitsdaten (NFDI4Health) oder das schon beschriebene Netzwerk CoRe-Net. Ein wesentliches Ziel von NFDI4Health ist die Zusammenführung von Daten der klinischen Forschung, Epidemiologie und Public Health. Dabei hat die Initiative gerade im Bereich der Standardisierung und Interoperabilität eine starke Anbindung an europäische und internationale Gruppen/Organisationen wie HL7 und CEN/CENELEC (Europäisches Komitee für Normung/Europäisches Komitee für elektrotechnische Normung). Die Daten der CoRe-Net-Datenbank werden in der aktuell zweiten Förderphase des Projektes nicht nur für Forschungszwecke, sondern für die Erstellung von thematischen Versorgungsberichten genutzt, die zur Unterstützung der kommunalen Versorgungsplanung gedacht sind. Über die Arbeitsgruppe „Data Matters“ ist auch diese Arbeit auf europäischer Ebene vernetzt.

Moreover, the COG classification of differentially expressed unigenes showed that most unigenes were classified as “general function prediction only”, which is similar to findings in the COG classification of all unigenes (Figures 1 and S3). The following categories include “secondary metabolites biosynthesis, transport and catabolism” (55 unigenes), “carbohydrate transport and metabolism” (54 unigenes), “replication, recombination and repair” (53 unigenes) and “transcription” (48 unigenes), indicating IBA exerts a broad range of effects on plant metabolism.

Although the importance of EBCR after an AMI is well established, several factors which pertain to its optimal application have not yet been fully ascertained [11, 12, 17]. Importantly, AMI survivors with a reduced ejection fraction (EF) represent a higher-risk subgroup and in some series are referred less often for these programmes [8, 18, 19]. Additionally, the impact of EBCR across different ranges of EF has been the focus of heightened interest [8, 19]. This stems from the fact that, although there are currently numerous parameters of potential interest in the prognostic assessment after an AMI, EF remains the most important parameter in terms of clinical decision-making and overall prognosis [3, 20]. Among the higher-risk subset of patients with a reduced EF, optimising strategies to reduce residual risk are of paramount relevance [2, 7, 19, 21].

Die Gegenwart der Mutter fasste der Analytiker im Konzept des „Haltens“ des Kindes zusammen, einem psycho-physischen Akt, wie er aus psychiatrischer Sicht als typisch für die Erzeugung von Atmosphäre galt (Tellenbach 1968) und dem Winnicott eine zentrale und symbolische Funktion zuschrieb.11 Es bezeichnete nicht nur „das wirkliche, physische Halten des Säuglings“, sondern die gesamte Tätigkeit der Mutter – oder, in Winnicotts Worten, „die gesamten Umwelt-Vorkehrungen“, auf räumlicher genauso wie zeitlicher Ebene (1974b : 56, siehe auch ebd.: 56–58, 62–70).12 Tatsächlich hat der Akt des Haltens neben der physischen immer auch eine chronologische Dimension, muss man doch jemanden (oder etwas) für eine bestimmte Zeit ergreifen, damit es sich tatsächlich um „Halten“ handelt. Für Winnicott war dieser temporale Aspekt zentral und er bezifferte die Dauer des Haltens genau, als Dauerhaftigkeit: mit 24 Stunden (Forrester 2017).

In modern breeding programs, identification of QTLs associated with desirable traits is being increasingly utilized in marker-assisted selection (MAS) and gene discovery (Kumar et al., 2017; Lu et al., 2017). There are many successful examples of using QTLs to increase quality, yield and disease resistance in cereal crops, such as rice (Takagi et al., 2013; Ali et al., 2017), maize (Mesterházy et al., 2012; Wu et al., 2016) and wheat (Tian et al., 2007; Zhang et al., 2017), as well as, in legumes (Wu et al., 2016; Lu et al., 2017). Many root traits are complex and expected to be controlled by many loci/genes, exhibiting highly flexible responses to environmental conditions (López-Bucio et al., 2003). In recent years, many quantitative trait locus (QTLs) for RA traits have been mapped in cereal crops, such as in rice (Ding et al., 2011; Topp et al., 2013), wheat (Ren et al., 2012; Christopher et al., 2013) and maize (Ruta et al., 2010; Burton et al., 2014). However, information on QTLs for RA traits remains scarce for soybean, with only two such published reports incorporating field evaluation (Liang et al., 2010; Abdel-Haleem et al., 2011). QTLs for BNF associated traits have been identified in several legumes, including common bean (Tsai et al., 1998; Souza et al., 2000), pea (Bourion et al., 2010) and Lotus japonicus (Tominaga et al., 2012). Even BNF related traits have been genetically mapped in soybean, albeit in greenhouse experiments with limited genome coverage (Tanya et al., 2005; Nicolás et al., 2006; Santos et al., 2013), and no QTLs for BNF traits have yet been successfully applied in soybean breeding programs for improving BNF capacity and yield.

Previous studies have shown LDHA expression predicts worse survival in clear cell renal cell carcinoma21, cholangiocarcinoma30, and breast cancer31. Taking advantage of multiple databases for human cancers and a novel aggregator called CANCERTOOL32, it is clear that LDHA expression is increased in a variety of human cancers (Supplementary Figure 6a). However, despite this increase in expression (and presumably activity), LDHA expression levels do not universally correlate with patient outcomes (Supplementary Figure 6b). The fact that LDHA expression does not always predict survival even in human tumors in which it is upregulated is consistent with our findings that Ldha expression is elevated in SCC but not required for SCC tumor growth in the mouse skin and may underlie fundamental differences in metabolic dependencies or enhanced metabolic flexibility of squamous cell carcinomas relative to other tumor types.

Ethylene output by organs increases dramatically at specific stages of the plant growth cycle, such as fertilization, ripening, senescence, abscission, and response to stresses . To determine the effect of 2ODDs on ethylene biosynthesis, we mapped the ethylene synthesis pathway (Fig. 6b). Ethylene is derived from the amino acid methionine (MET), catalyzed by AdoMet synthetase and 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, to provide ACC precursors. ACC is then converted into ethylene by ACO, a member of the 2ODD family. Fig. 6Characterization of Sl2ODDs involved in ethylene biosynthesis pathway. a Expression profiles of 7 ACO genes throughout the tomato life cycle. b Schematic representation of ethylene biosynthesis pathway.

Descriptive statistical analysis was performed with commercially available software packages (SPSS, version 11.1 (SPSS GmbH, Munich, Germany) and R, version 2.0 ). We used the Kaplan–Meier estimator for univariate statistical analysis and the Cox regression model for multivariate analysis. P < 0.05 was considered to be significant. A log-rank test was applied for assessing statistical differences between survival curves. The χ2 test was used to investigate the relationship between topoisomerase IIα expression and histological grading and to analyze the association between topoisomerase IIα and c-erbB2 overexpression with hormone receptor status or stage.

In comparison with other epithelia, keratinocytes generate particularly strong intercellular connection that enables the collective migration occurring even in an environment with little or highly dispersed ECM substrates for specific integrin receptors . Junction between cells can promote wound reepithelization with limited or varied adhesion to ECM and facilitate wound closure in the absence of specific integrins. Therefore, a key area of research that will allow describing the precise mechanism involved in slow or accelerated wound healing is to investigate the expression of specific integrins, components of the cytoskeleton, and target proteins involved in mechanotransduction, as well as conduct a thorough analysis of mechanical wound environment .

Thus, the results of the analyses of the first lumbar vertebrae are also consistent with the test predictions. The finding of differences in shape between the healthy human, chimpanzee, and orangutan specimens is consistent with the first test prediction, while the finding that pathological human vertebrae are closer in shape to chimpanzees than are healthy human vertebrae is consistent with the second test prediction.

ALFSim is a genome evolution simulator and was used (Dalquen et al., 2012) to simulate the evolution of more distantly evolved subpopulations. Therefore, coding and intergenic nucleotide sequences according to the genome annotation were extracted from the genome reference fasta file. This extracted sequences served as input for ALFSim. From the ALFsim output, we selected a simulated subspecies having a nucleotide dissimilarity of 0.8% resulting in 21,000 SNPs, 100 InDels and three duplications. The resulting fasta file was used for read simulation, construction of a heterogeneous population and prediction of variants.

Recently, a highly conserved family of adiponectin paralogs has been discovered, and designated the C1q tumor necrosis factor (TNF) related proteins (CTRPs). Exhibiting a similar structure as APN, each CTRP consists of four distinct domains including a N-terminal signal peptide, a short variable domain, a collagen-like domain, and a C-terminal C1q-like globular domain [14, 15]. Of all CTRPs identified to date, CTRP9 shares the greatest amino acid overlap with APN in its globular C1q domain . We recently demonstrated that CTRP9 is an endothelium-dependent vasodilator and CTRP9 treatment attenuates diabetes-induced endothelial dysfunction . Moreover, others and we have recently demonstrated CTRP9 protects the heart against acute ischemic/reperfusion injury [18, 19]. Most importantly, a recent study demonstrated that, distinctly different from adiponectin-knockout (which lacks phenotypic change under physiologic conditions), CTRP9-knockout mice gain more weight with normal diet and develop spontaneous insulin resistance and type 2 diabetes . In contrast, CTRP9 transgenic mice are protected from diet-induced obesity and metabolic dysfunction . These results suggest CTRP9 likely possesses more important metabolic regulatory function than other adipokines. However, the role of CTRP9 in dysregulated platelet hemostasis under diabetic conditions has not been previously investigated.

In this work, the operational workflow of ChemDataExtractor has been extended to incorporate a semi-supervised and probabilistic ML algorithm for quaternary relationship extraction. Since ChemDataExtractor contains trained CNER tools, it is well suited to incorporating a semi-supervised approach to relationship extraction such as the Snowball algorithm14. The original Snowball algorithm operates as follows: it uses approximately 4,000 seed examples of Organisation-Location pairs to perform binary relationship extraction. The process starts with a set of seed examples of a known positive relationship, each assigned a full confidence score of 1.0. The algorithm is then trained by parsing a corpus of documents to find sentences therein which contain the seed examples. These sentences are clustered based on textual similarity and used to learn typical patterns that specify the relationship. New relationships can be identified by comparing previously unseen sentences to these learnt patterns and checking for a minimum level of similarity. This level of similarity also helps to determine the confidence score of the new relationship.

The three most important explanatory variables of perceived stress in this study were disease, perceived social support and work situation. An American study of older adults identified loneliness, neighbourhood and financial strain as particularly important predictors of perceived stress . Different groups of respondents may have different “dominance profiles”of perceived stress, which is indicated in our study.

Quantitative traits are important in medicine, agriculture, and evolution but, until recently, few polymorphisms have been shown to be related in these traits. Genome-wide association studies (GWAS) is a statistical technique that has been used successfully in the identification of over 65,000 single-nucleotide polymorphisms (SNPs) that are connected to various traits or diseases (MacArthur et al., 2017). Typically, GWAS are carried out using single-locus models (i.e., testing for association between each SNP and a given phenotype independently using linear or logistic regression). However, according to the popular “polygenic theory” (Li et al., 2015b; Dudbridge, 2016), complex traits are often controlled by multiple SNPs collectively. Due to the need to eliminate multi-testing corrections that decrease statistical power, a better understanding of the underlying heritable genetic architecture of complex traits requires one to move beyond single-locus models to multivariate linear regression models that incorporate the joint effects of multiple SNPs explicitly (Ma et al., 2013).

Die feministische Friedensforschung leitet die Geschlechterstereotype aus der Analyse traditioneller Konzepte von Frieden und Sicherheit ab. Nach Tickner (2019) wird Sicherheit in der herkömmlichen Auffassung mit starker militärischer Maskulinität assoziiert, während Frieden mit schutzloser Weiblichkeit, der Frau als dem Opfer von Unsicherheit, verbunden wird. Feministische Forschung stellt die oftmals als natürlich-frauenspezifisch perzipierte essentialistische Verbindung von „Frau und Frieden“ oder „weiblich ist gleich friedlich“ oder „weiblich ist gleich schutzbedürftig“ ebenso in Frage wie die Verbindung von „männlich und militaristisch“, „männlich und schützend“ oder „männlich und verteidigend“. Sie fordert damit die deskriptiven traditionellen Geschlechterstereotype heraus und setzt der These der friedvollen Frau die präskriptive Auffassung entgegen, dass Frauen Akteure aller Facetten von Friedensstiftung („peacemaking“) seien sollen (Tickner 2019). Diese präskriptiven Stereotype, die aus feministischer Perspektive auch der globalen Agenda für „Frauen, Frieden und Sicherheit“ zugrunde liegen, verfolgen eher einen Ansatz der Gender-Neutralität.

Een prospectief verzameld cohort van 1170 opeenvolgende patiënten die RARP ondergingen in twee hoogvolumecentra tussen 2018 en augustus 2021 werd retrospectief onderzocht. Alle patiënten ondergingen een MRI-scan voor de operatie. De diagnose PCa werd gesteld met systematische biopten, MRI-targeted biopten of beide. Met het Soeterik-nomogram werd de zijdespecifieke kans op EPE berekend voor elke prostaathelft met complete data (PSA-densiteit, biopt Gleason-scores, radiologisch tumorstadium). Modeldiscriminatie en -kalibratie werden onderzocht middels de area under the curve (AUC), calibration-in-the-large en calibratiecurves.

In our implementation of the model, competing actions are suppressed by lateral inhibition in the population representing thalamocortical neurons, independent of BG network integrity. Our model does not elaborate on mechanisms of this inhibition. However, one can speculate that GABAergic neurons in the thalamic reticular nucleus may serve their purpose by receiving focused excitatory inputs from thalamocortical neurons and sending diffused inhibition back to them (Pinault and Deschênes, 1998) or fast-spiking, local GABAergic inhibitory interneurons in the neocortex may play the role since they are directly receive thalamocortical afferents, contact excitatory cortical neurons in a disynaptic way and exert fast and strong inhibition (Miller et al., 2001; Hull and Scanziani, 2007).

Analyzing Figure 2, it can be noticed that mixture of grape seed and sea buckthorn meal decreased the CYP1A2 and CYP3A29 specific activities at hepatic level in a significant way, whereas at renal level, the CYP1A2 specific activity was significantly increased (p < 0.01). Moreover, the presence of OTA and AFB1 in piglet’s feed decreased significantly the hepatic CYP1A2, CYP2E1 and CYP3A29 specific activities (p < 0.001), whereas in the kidney, the CYP1A2, CYP2E1 and CYP3A29 specific activities were increased significantly (p < 0.01). The concomitant administration of the mixture of grape seed and sea buckthorn meal and OTA and AFB1 determined the restauration of specific activity levels to control ones only in the kidney samples.

Table 9 shows the benchmarking table, presenting existing state-of-art classification methods and comparing them against the proposed method. Each row in the table shows different authors’ work in this area and the columns show the methods, number of X-ray images used, and results of the experiment. We used the highest number of images for our experiment compared with any other work in this area. To the best of our knowledge, our NasnetMobile model achieved the highest accuracy of 99.80% among all existing methods for binary classification of COVID-19 vs. viral pneumonia. Additionally, for the first time ever, we have performed the binary classification into COVID-19 vs. bacterial pneumonia and COVID-19 vs. tuberculosis disease classes with remarkable accuracies of 99.84% by Densenet201 and 99.31% by VGG16 model, respectively. Our results are very consistent with the previous studies on Densenet . These studies have shown superior performance of Densenet169 applied to COVID CT/X-rays. The key advantages of the Densenet are its ability to alleviate the fundamental problem of vanishing-gradient. As a result, the feature extraction process is boosted up for its reuse, thereby reducing the number of parameters.

We then asked whether maternal mRNA degradation in human embryos after fertilization depends on ZGA. Both in vitro controls and α-amanitin-treated human zygotes successfully developed to the 8-cell stage (Fig. 1a). These 8-cell embryos were collected for RNA-seq analysis. Significantly, transcripts of Clusters II and III were stabilized in α-amanitin-treated embryos (Fig. 1d). However, α-amanitin treatment only blocked the degradation of nearly half of the transcripts of Clusters II and III in mice. Thus, a ZGA-dependent mRNA decay pathway was found to operate during human MZT, in which it played a more important role than in mouse MZT.

Importantly, under these conditions, AT dysfunction disrupts fat metabolism in adipocytes at multiple sites. Notably, an increased resistance to insulin results in elevated lipolysis, resulting in elevated levels of circulating FFAs. In addition to insulin resistance, reduced sensitivity to catecholamines also decreases metabolic flexibility. Fat overflow, together with low-grade systemic inflammation, results in ectopic lipid deposition in the liver, muscle, and pancreatic β-cells. Lipid deposition in the liver and muscle directly increases insulin resistance (Snel et al., 2012), while in pancreatic β-cells it is believed to be lipotoxic, decreasing their ability to secrete insulin (Robertson et al., 2004). A combination of insulin resistance and decreased insulin secretion is expected to increase the risk for T2DM.

Im vorliegenden Fall ließ das schwach positive PCR-Signal aus dem prämortalen Abstrich vermuten, dass die Infektion der Spenderin mit SARS-CoV‑2 bereits weitestgehend abgeklungen war. Wahrscheinlich hatte die Spenderin keine oder nur leichte Symptome, da sowohl die Anamneseerhebung im Krankenhaus als auch durch die Gewebeeinrichtung unauffällig war. Bedingt durch den im Grenzbereich liegenden CT-Wert des positiven prämortalen Tests ist das negative Ergebnis des postmortalen Tests nicht unerwartet. Die jeweiligen CT-Werte der einzelnen Tests (Tab. 1) entsprechen den in der Literatur beschriebenen Daten . Ein falsch positives Ergebnis erscheint daher sehr unwahrscheinlich, allerdings kann eine Probenkontamination nicht vollständig ausgeschlossen werden. Die erneute Prüfung der prämortalen Abstrichproben war aufgrund fehlender Rückstellungen nicht möglich.

To determine the enzymatic characteristics, CTendo45 and its mutants were heterologously expressed in P. pastoris and purified using Ni2+ affinity chromatography. The similar protein yields implied that the attachment of N-glycans to different sites has hardly any influence on efficient enzyme expression (Additional file 1: Table S2). SDS-PAGE analysis showed that each single mutant with an additional N-glycosylation site presented as a single band at approximately 34 kDa, which is higher than that of the wild type (approximately 32 kDa) (Fig. 3a) because of the artificial attachment of oligosaccharides under the same culture conditions . After the deglycosylation of N-linked glycans with PNGase F, the enzyme molecular mass decreased to 28 kDa, which was consistent with the size of the N-deglycosylated mutant T90A. The molecular mass of the double-mutant R67S/T90A is nearly the same as that of the wild type (Additional file 1: Fig. S3). Glycoprotein staining further confirmed that residue N88 was the unique N-glycosylation site in CTendo45. Moreover, this result indicated that the N-glycan was successfully attached to each additional mutation as a single clear band (Fig. 3b). In particular, it is worth mentioning that the bands of T90A and deglycosylated wild-type also appeared in glycoprotein staining, which resulted from O-linked glycans, as there are three predicted O-glycosylation sites (T52, T235, and T237) in CTendo45. The mass spectrum of the tryptic digest of CTendo45 and its mutants further confirmed the addition or deletion of N-glycan in a specific position (Additional file 1: Table S3 and Fig. S4).Fig. 3SDS-PAGE analysis of purified recombinant enzymes.

Il est utile de bien veiller à analyser séparément les tiers moyens/antérieurs et les portions postérieures et tout à fait inférieures. L'ostéose iliaque condensante se présente sous forme d'une image d'ostéocondensation triangulaire de la berge iliaque à limites nettes sans érosions articulaires elle est facilement reconnue sur les radiographies ou le scanner et peut poser des problèmes d'interprétation en IRM . Dans les sacroiliites inflammatoires, l'atteinte est bilatérale, les érosions, l'ostéocondensation et les ponts transarticulaires sont intriqués et panachés . Elles surviennent n'importe où, c'est-à-dire que les lésions inflammatoires peuvent survenir dans le tiers antérieur/moyen des articulations, tout comme les formes arthrosiques mais également dans la partie la plus postérieure, et dans la partie tout à fait inférieure, pratiquement toujours respectées par les remaniements de type mécanique . Les modifications sacro-iliaques de la spondylarthropathie ankylosante sont le plus souvent bilatérales et plus ou moins symétriques dans les formes chroniques mais elles sont très généralement asymétriques dans les formes débutantes (ainsi que de façon plus prolongée dans d'autres spondylarthropathies inflammatoires, arthrite réactionnelle et rhumatisme psoriasique par exemple).

近年来，影像引导下肿瘤热消融已证实是一种有发展前途且安全有效的治疗手段。目前，国内外常用的肺癌热消融手段除了微波还有射频和激光等。微波、射频及激光治疗肺癌均可对病灶原位有效灭活，减轻肿瘤负荷，近期疗效确切，中、远期疗效待观察分析。肺癌微波、射频及激光消融常见并发症有气胸、咳血、胸腔积液，少见并发症有肺出血、支气管胸膜瘘、肺部感染。射频消融不宜用于靠近大血管的肿瘤。治疗费用高于微波消融。激光消融特别适用于大小为2.0 cm-3.0 cm位于肺中上部的病灶。其消融形状比射频合理，肺出血并发症低于射频。经皮穿刺微波消融治疗周围型肺癌或经纤维支气管镜微波消融治疗中心型肺癌，其优点在于对病灶原位灭活的同时，能限制对正常含气肺组织的损伤，微波热消融还可以增加局部血流和淋巴循环，加快组织再生和修复能力，提高机体免疫反应。气胸、皮肤烫伤、肺出血等并发症发生率已明显降低，无治疗相关死亡病例。微波消融治疗肺癌的缺点是虽然取得良好的肿瘤局部消融效果，但因肿瘤不规则或肿瘤体积较大存在消融不完全的可能，这些存活肿瘤细胞将成为肿瘤复发和转移的隐患。微波联合放疗治疗肺癌可以消灭微波消融的肿瘤残留问题并减少肿瘤细胞的热耐受性，提高微波消融治疗效果。微波消融治疗肺癌是一种新兴肺癌微创热消融治疗模式，属局部治疗手段，进一步研究其与放疗、化疗、生物治疗、基因治疗等全身治疗手段的协同或互补作用机制，其理论将为肺癌治疗提供科学依据，以肺癌微波消融为基础的联合治疗方法将有希望成为减轻肺癌患者肿瘤负荷、减少肿瘤细胞远处转移、提高肺癌治疗疗效、延长癌症患者生存期和提高生活质量有效方法。

To prevent cancer means, therefore, to inhibit one of the above-described steps of carcinogenesis. However, the majority of chemopreventive agents acts at the initiation step, i.e., via a neutralization of the carcinogen (stimulus) or via an attenuation of its DNA-damaging action. Apart from the genetic background, which already includes already existing inherited gene mutations (germline mutations), the newly acquired mutations in the body cells (somatic mutations) may result from the exposure to three carcinogen types. This includes physical (UV, ionizing radiation [IR]); chemical (cigarette smoke, benzo[a]pyrene, asbestos, aflatoxin, some hormones and hormone-like molecules, and many others), and biological carcinogens (e.g., papillomaviruses, hepatitis B and C, Helicobacter pylori, etc.) . Chemopreventive agents may suppress a carcinogen or its secondary effects via different mechanisms. These mechanisms include an inhibition of chronic inflammation, which was reported as a predisposition to several cancer types; scavenging of reactive oxygen species (ROS) and other free radicals, which result from UV, IR, or chemical exposure and leads to DNA damage; stimulation of the innate immunity in order to recognize and eliminate a malignant-transformed cells; inhibition of oncogenic nuclear factors such as NF-kB and AP-1; and many others .

Several reports have shown that hydrogenases are implicated in the virulence of S. enterica (Maier et al., 2004; Zbell et al., 2008; Lamichhane-Khadka et al., 2015). In Helicobacter pylori, hydrogenases participate in the process of energy generation, which is important for efficient bacterial colonization within the acid environment of mouse stomach (Olson and Maier, 2002). In Edwardsiella ictaluri, it has been shown that replication of the bacteria in macrophages required modulation of the pH of the bacteria-containing vacuole through an acid-activated urease (Booth et al., 2009; Baumgartner et al., 2014). In our study, we found that compared to the wild type, TX01Δsip2 completely lost the capacity to replicate in fish PBL, and was significantly impaired in the ability of tissue dissemination and inducing mortality in the host. These results indicate that Sip2 is a virulence factor that is essential to the ability of E. tarda to multiply intracellularly and cause lethal infection.

On the other hand, training courses and working hours of residents have been affected by the financial issues of hospitals and economic pressures prevailing in medical centers ( 9 ). As future health care practitioners, the better they are trained with opportune planning and practical training in a proper context, the more qualified employees would be to provide high-quality services ( 10 ). Over the past few decades, the development of structured and efficient approaches to surgical courses, including attention to setting primary educational goals, efficient evaluation methods based on receiving feedback, and the use of effective teaching models has been highly emphasized ( 11 ). In this regard, several educational models, including the Zwisch model, which provides both faculty and residents with specific stages of supervision, allow for adequate, safe training in a graduated manner to develop operative autonomy and fully trained surgeons. The other excellent model is Briefing-Intraoperative-Debriefing (BID) model that walks the learner through the surgery in three stages. During the briefing stage, the attending surgeon starts the conversation with a brief question about the goal of the operation or previous experiences. In the intraoperative stage, the attending surgeon will still coach and guide the resident through the operation and, finally, in the debriefing stage, the preceptor and learner debrief about the encounter. Also, assessment tools such as Objective Structured Assessment of Technical Skills (OSATS) are widely used to score the skills of each surgical trainee in performing or assisting in real operations. Similarly, Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) is a 9-item surgical evaluation tool designed to assess technical competence in surgical trainees using behavioral anchors ( 12 - 15 ).

The causal link between raised BMI and some long term illnesses leads to statistical difficulties in separating their effects on need for social care [6, 8]. In order to refine our estimates of the need that is ultimately attributable to BMI we constructed two additional measures of limiting long term illness and consider these separately in statistical analysis. One of the additional measures does not count individuals with only diabetes in its definition of long term illness, while the other does not count individuals with either diabetes or stroke, heart attack or angina. Both of these conditions are linked to raised BMI and the additional variables will allow the effect of other long term illnesses on need for social care to be more precisely identified. HSE does not distinguish between types of diabetes but over 90% of diabetes cases are type 2 , and of these approximately 79% to 83% are attributable to obesity and overweight [17, 18]. Approximately 34%–58% of cases of heart disease or stroke are attributable to overweight or obesity . Other diseases are also linked to raised BMI but to a lesser extent, and as they also tend to occur less frequently in our sample we did not attempt to adjust for them.

To further disambiguate whether the relationship between AMPAR current amplitude and spine length was due to differences in receptor expression or differences in spine neck resistance, we examined the relationship between isolated AMPAR-currents (NMDARs were blocked with 50 µM D-AP5) and spine length in the presence of cyclothiazide (CTZ, 100 µM) to inhibit AMPAR desensitization. CTZ increased the maximum synaptic conductance and slowed the time course of the AMPAR-mediated conductance changes. Both effects will minimize the impact of the spine neck resistance on measurement of the synaptic current. Examples of uncaging-evoked AMPAR currents at positive and negative potentials in the presence of CTZ are shown in Figure 6F,G. We observed a significant correlation between AMPAR current amplitude and spine length in the presence of CTZ at both positive and negative voltages (at -70 mV R = 0.92, p=2.5e-5; at +40 mV R = 0.95, p<1e-5; n = 6 spines, 3 shafts) (Figure 6H). We also observed a significant correlation between AMPAR-mediated charge transfer and spine length in the presence of CTZ (R = 0.66, p=0.02, n = 6 spines, 3 shafts) (Figure 6I) further supporting the hypothesis that long spines display lower AMPAR density.

Thank you for highlighting this. On reflection, we feel this sentence is not needed and have removed it. We have also used this opportunity to re-write the Statistical Analysis section of the Methods (page 11) to make this clearer and more concise (see Response to comment #6 above).

Weiterhin wurde von einem anfänglichen Problem berichtet, bei dem nicht genügend Daten für die Durchführung einer Aufgabe verfügbar waren. Es fehlten Instanzen für eine Design-Thinking-Methodendatenbank, wodurch das Entwicklungsziel gefährdet war. Deshalb entschied sich die Gruppe dafür, die Methodendatenbank zu verfeinern und durch eine verbesserte Struktur zu ersetzen. Dabei wurden weitere Methoden recherchiert, so dass die Methodendatenbank gewachsen ist. Um diese Methoden mit Alexa abfragen zu können wurden Intents entwickelt, konzipiert und per Screensharing mit Testnutzern getestet. Die Erkenntnisse sind dann in einem Vorgehensmodell für weitere CUI-Projekte verarbeitet worden.

Por otro lado, se han creado instituciones, bases de datos, recursos bioinformáticos y directrices de trabajo producto del consenso de la comunidad científica, los cuales son usualmente ignorados o se desconocen, por lo que se incurre en errores metodológicos y se ignoran los términos y la nomenclatura oficial, lo que lleva a nombrar la población de vesículas extracelulares obtenida a partir de conceptos erróneos, o cuyo origen e identidad no se ha demostrado adecuadamente. Ello genera falta de homogeneidad y mucha confusión en los resultados reportados y conduce a la imposibilidad de reproducirlos. En este sentido, las instituciones oficiales recomiendan términos y una nomenclatura, pero, hasta donde se pudo comprobar, no hay una publicación que recopile los términos oficiales indexados en la ontologia génica y otros vocabularios controlados. En consecuencia, no siempre se consideran todos los aspectos y recursos de este campo a la hora de plantear proyectos y estudios que resulten integros.

Next generation sequencing has greatly accelerated the accumulation of genomics data. Different protocols targeting the genome, epigenome and transcriptions are widely used . In essence, all protocols capture biological sequences of interest while adding adaptors and other sequences to facilitate cost effective sequencing. An obvious examples is the use of indices or barcodes allowing researchers to multiplex sequencing experiments . In addition recent protocols include random oligos in the library construction to correct for PCR and other biases . As the length of such auxiliary sequences increases so is the chance that sequencing errors occur in these key sequences. In the best case these errors lead to some sequences being lost to the downstream analysis, but in the worse case sequences can be mixed up between samples leading to analytical noise. A compounding complication is that error rates of current sequencing instruments vary and is not obvious how to select an appropriate strategy to process the raw data.

Следует отметить, что ранее мы описывали похожую выборку больных ЯК из Западной Сибири (Тикунов и др., 2020) и в целом данные по долям последователь- ностей из семейств, принадлежащих типам Firmicutes, Bacteroidetes и Actinobacteria, в обоих исследованиях существенно не различались; лишь доля последовательно- стей Proteobacteria в предыдущей работе была несколько меньше. Также в настоящем исследовании, в отличие от предыдущего, у пациентов с ЯК не обнаружены последо- вательности архей. Отсутствие существенных различий между 16S-профилями кишечных микробиомов двух групп больных ЯК свидетельствует об определенных ре- гиональных особенностях микробиоты таких пациентов. Вместе с тем в данное пилотное исследование включены лишь по 8, 18 и 8 образцов пациентов с СРК и ЯК и здоровых участников соответственно. Для вывода о том, являются ли обнаруженные тенденции закономерностями, необходимо продолжение исследований с использованием большего количества анализируемых образцов.

This finding is also supported by the previous work of Speroff who in reflection on their own correlations using the SAQ in 1,406 respondents stated that "the stress recognition items do not contribute positively towards the construct of safety climate as intended and should be excluded from the SAQ" . We believe that the inclusion of the Stress Recognition subscale in the SAQ does not affect its overall reliability. However, we have strong concerns that the stress recognition subscale of the SAQ affects its validity. We recommend that this domain be omitted from overall safety climate scale score calculations, and clearly identified as a distinct construct.

Unsere vierte Hypothese konnte nicht bestätigt werden – es zeigten sich keine Unterschiede bei der Wahrnehmung des Feedbacks im Hinblick auf den sozioökonomischen Status der Schüler*innen (H4). Eryilmaz und Sandoval-Hernández (2021) weisen darauf hin, dass der sozioökonomische Status nur eine kleine Rolle bei der Wahrnehmung von Feedback spielt. Unsere Befunde unterstreichen diese Erkenntnis. Zusätzlich konnten wir zeigen, dass es keine Unterschiede bei der Fairness, dem Nutzen und der Akzeptanz des wahrgenommenen Feedbacks im Distanzlernen in Bezug auf den sozioökonomischen Status gab. Diese Ergebnisse sollten auch im Präsenzunterricht überprüft werden.

In this study, we used voltage clamp experiments to directly measure SOCE channel activity (i.e. ISkCRAC magnitude, voltage dependence, pharmacology, and rate of activation) in myotubes from two different mouse models of heat- and halothane-induced sudden death (i.e. Y524S/+ and dCasq-null mice). We found that rate of ISkCRAC activation during repetitive depolarization at room temperatures was accelerated in both Y524S/+ and dCasq-null myotubes in the absence of a change in current magnitude or voltage dependence. While the rate of ISkCRAC activation was increased at PT for all genotypes, the maximum rate of ISkCRAC activation at PT was significantly faster than WT only for myotubes derived from dCasq-null mice. Finally, we found that azumolene, a more water-soluble dantrolene analogue, did not significantly alter either ISkCRAC magnitude or rate of activation. These results indicate that while myotubes from MH mice exhibit an increased susceptibility for activation of SOCE during repetitive depolarization, the SOCE channel in myotubes is not a direct molecular target of azumolene.

RKIP是近年来发现的一种新的肿瘤转移抑制因子，广泛表达于哺乳动物的脑、心、肝、肺及睾丸等组织，参与质膜生物合成、神经发育、精子发生、细胞凋亡等生理病理过程。近年来研究[2, 3]显示，RKIP不仅可以干扰Raf-1-MEK1/2-ERK1/2信号通路，而且还可以抑制NF-κB和G蛋白偶联受体激酶等信号传导过程。自2003年Fu等研究发现PKIP可以抑制肿瘤细胞转移的作用后，PKIP成为肿瘤领域的一个新的热点。Lee等[5, 10]研究发现RKIP在肝癌中的表达明显低于邻近的正常肝组织，增加RKIP的表达可以减少肝癌细胞的增殖和迁移。RKIP在甲状腺癌中的表达低于正常的甲状腺组织，外源性的RKIP可以抑制甲状腺癌细胞的生长。还有研究[8, 12]发现PKIP在乳腺癌的原发病灶中高表达，其表达与乳腺癌的类型、分化程度、大小、ER的表达无关，但在转移淋巴结中低表达或无表达；RKIP在正常黑色素细胞中表达量最高，黑色素瘤次之，黑色素瘤转移灶最低或缺失；过表达RKIP可以抑制高转移性黑色素瘤细胞的转移能力。本研究通过检测肺鳞癌组织及其癌旁正常组织中RKIP基因的表达发现：RKIP mRNA在肺鳞癌组织中表达的阳性率明显低于癌旁正常组织（P < 0.05），在有淋巴结转移者中的表达阳性率明显低于无淋巴结转移者（P < 0.05），但与患者的性别、年龄、肿瘤的大小及分化程度无关（P>0.05）；RKIP蛋白在肺鳞癌组织中表达也明显低于癌旁正常组织（P < 0.05）。可见RKIP在肺鳞癌组织中表达结果与其它肿瘤相似。

(A) Sample persistent sodium current recordings at -20mV from C373F and C373F/E1784K NaV1.5 at pH 7.4 and pH 6.0. (A inset) Sample persistent sodium current recordings at -20mV normalized to peak current from C373F and C373F/E1784K NaV1.5 at pH 7.4 and pH 6.0. (B) Persistent current normalized to peak current for C373F and C373F/E1784K NaV1.5 at pH 7.4 and pH 6.0 at membrane potentials between -30mV and 0mV. The E1784K mutant increases the fraction of persistent current. When extracellular pH is lowered to pH 6.0 there is a larger increase in the fraction of persistent current in CF/EK compared with CF. (C) Sample gating currents recorded during a protocol to measure gating current deactivation voltage-dependence. (D) Sample gating currents recorded to measure the time course of voltage-sensor deactivation at -150mV. (E) Voltage-dependence of gating current deactivation for C373F and C373F/E1784K NaV1.5 at pH 7.4 and pH 6.0. The inverse of the amount of charge deactivating at a given voltage is plotted to facilitate comparisons with the outward charge-voltage relationship. The voltage-dependence of gating current deactivation is shifted in the depolarizing direction by the E1784K mutant. (E inset) To measure the voltage-dependence of gating current deactivation, cells were hyperpolarized to membrane potentials between -150mV and +20mV (b) following a depolarization pulse to +50mV (a). This was followed by depolarization to +50mV (c). (F) Time course of gating charge deactivation at -150mV for C373F and C373F/E1784K NaV1.5 at pH 7.4. Time courses at pH 6.0 overlap those recorded at pH 7.4 and are therefore not shown. The E1784K mutant increases the fraction of charge which recovers with the fast time constant of recovery and decreases the fraction of slow charge return. (F inset) To measure the rate of gating current deactivation, we depolarized cells to 0mV (c) following a conditioning pulse to 0mV (a) and a recovery pulse of variable length to -150mV (b).

All our results suggest that EGCG partially restores T cell activity by inhibition of PD-L1/PD-1 signaling, resulting in inhibition of lung cancer growth. Thus, we present a new concept: green tea catechin acts as an immune checkpoint inhibitor, leading to cancer prevention and treatment.

La légionellose est une maladie infectieuse bactérienne, causée par un bacille à gram négatif, dont il existe plusieurs espèces et sérogroupes . Legionella pneumophila est le plus souvent mise en cause et tout particulièrement le sérogroupe I (Lp1), connu depuis l’épidémie de 1976 lors d'un congrès de l'American Légion [1, 2]. Il s'agit d'une bactérie ubiquitaire, exigeante, à développement intracellulaire, qui a pour habitat le plus répandu les eaux douces naturelles et les sols humides [1–3]. La légionellose est une maladie à déclaration obligatoire dans plusieurs pays européens mais souvent sous-déclarée car elle est le plus souvent sporadique plutôt qu’épidémique [1, 2]. La contamination se fait par l'inhalation de gouttelettes d'eau infectée par le germe présent dans les systèmes de canalisation d'eau ou de climatisation [1–3]. Les tours refroidissantes, les saunas, les bains à remous, les fontaines, les salles de bains, les respirateurs, les nébulisateurs sont connus comme des sources d'infection à Legionella [1–3]. La légionellose se manifeste progressivement sous deux tableaux: la forme sporadique ou fièvre de Pontiac qui ressemble à un syndrome grippal, la forme plus sévère qui est pneumonie pouvant conduire à une faillite multisystémique et au décès [1–5]. La rhabdomyolyse est complication rare de la légionellose dont le mécanisme reste inconnu [6, 7]. Cette présentation sévère est signalée dans environ 15% de cas; ses complications induisant un taux de mortalité de plus de 50% pouvant s’élever à 80% en fonction du terrain de l'hôte [6, 7].

Reminiscent of cardiovascular toxicities from cancer therapies, the recent coronavirus disease of 2019 (COVID-19) pandemic is a clear example of how cardiotoxicities can arise unexpectedly and how adaptable clinicians need to be to deal with a constant flow of new cardiotoxic agents and their complications. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has arisen as an emergent cardiotoxic agent, underlying COVID-19. By July 2020, more than 18 million confirmed cases and 600,000 deaths had been reported globally (4). In positive cases, direct and indirect cardiovascular (CV) injury has been noted as a prominent feature (5, 6), mediated by hypoxia, inflammation, demand ischemia, microvascular dysfunction, or thrombosis (7–10). Around the world, our patients have been physically and socially distancing themselves from others and avoiding physical entrance of health care facilities, in order to limit exposure in COVID-19. Correspondingly, health care institutions have restricted non-emergent in-person visits, to curb the rates of morbidity and mortality from COVID-19. Individuals with known CV disease or risk factors have been at greater risk of morbidity and mortality in COVID-19 (11–16), as is similar in Cardio-Oncology (17). Therefore, there is an urgent need for various avenues of innovation to predict cardiovascular risk and customize preventive, diagnostic, and management care plans in the setting of cancer therapies, especially during the pandemic and beyond. Here, we briefly describe forms of innovation implemented during the pandemic, as well as innovative tools being explored for utility beyond the pandemic (Figure 1).

From the above considerations, it can be inferred that it is not only the type of food an individual eats, but also where and how he or she eats that is important for his or her health and well-being. It has been widely studied that eating as a family, in addition to the pleasure of sharing time with loved ones, has important health benefits . Different studies have shown that the quality of life for people who eat as a family is improved, as their diet is generally more balanced and of a higher quality . Eating as a family is also a preventive factor against diet-related diseases such as obesity and eating disorders .

To investigate and visualize the gene expression correlations of 34 ripening-associated DzERFs with some ripening-related genes previously identified by Teh et al. [from an RNA-Seq study of durian cv. Musang King, including ACS, ACO, methionine gamma lyase (MGL), pectinesterase (PME40), S-adenosylmethionine (SAM) synthase, β-D-xylosidase 1 (BXL1), cytochrome P450 71B34 (CYP71B34), sulfur deficiency-induced 1 (SDI1), and DPNPH] and Khaksar et al. [L-tryptophan aminotransferase 1 (TAA1) and indole-3-pyruvate monooxygenase (YUCCA4)], the conserved domain of each enzyme (based on an HMM) was first obtained from the Pfam protein database (http://pfam.xfam.org/). This sequence was used as a query to search against the de novo assembled transcriptome database of durian fruit cv. Monthong and the Musang King genome (i.e., ACS (XM_022901720.1), ACO (XM_022903266.1), TAA1 (XM_022878297.1), YUCCA4 (XM_022900772.1), MGL (XM_022917834.1), PME40 (XM_022875865.1), SAM synthase (XM_022915017.1), BXL1 (XM_022866549.1), CYP71B34 (XM_022919875.1), SDI1 (XM_022914153)). The network of TFs and candidate target genes was visualized using Cytoscape (v3.7.1, USA). A correlation heatmap was generated using MetaboAnalyst 4.0.

Ao se utilizar a fibra dupla radial, não houve necessidade de tumescência para alcançar uma taxa de 100% de oclusão nos pacientes em 30 dias, assim como demonstrado no estudo de Galego et al.25 com fibra radial e sem tumescência. Mesmo utilizando menor energia (LEED de 30 J/cm), não houve comprometimento do resultado tardiamente. Pode-se pensar em utilizar tal quantidade de energia, já que, neste estudo, verificou-se uma taxa de hematomas um pouco maior, assim como na intenção de diminuir a chance de parestesia sem comprometer a taxa de oclusão.

We identified cis-regulatory elements in the 3′ UTRs of myelin-localized mRNAs. To begin, we bioinformatically identified 3 motifs common to the mbpa, eif4ebp2, and fmr1 3′ UTRs. Each motif was necessary for localization, but only 4 sequences were sufficient to drive mRNA to nascent sheaths. However, we are not able to exclude the possibility the motif 1 in the mbpa 3′ UTR contributes to mRNA localization. We interpret these data to mean that mbpa motif 3, eif4ebp2 motif 1, eif4ebp2 motif 3, and fmr1 motif 3 are minimal cis-elements that regulate mRNA localization to nascent sheaths in vivo. The 4 other primary sequences isolated from the candidate 3′ UTRs, while necessary for localization, were not sufficient and thus require additional localization signals present in the 3′ UTR, which are currently unknown.
