Call rate was related to the presence of a competitor but not habitat quality, and thus could constitute a useful behavioral metric for interactions that are challenging to detect in an occupancy framework. Quantifying multivariate distance between groups of vocalizations provided a rigorous means of discriminating individuals with ≥20 vocalizations, and a flexible tool for balancing Type I and II errors. Therefore, it appears possible to estimate site turnover and demographic rates, rather than just occupancy metrics, in PAM programs. These three methods can be applied individually or in concert and are likely generalizable to many acoustically active species. As such, they can provide substantial opportunities for improving inferences from PAM data and thus improve conservation outcomes. This article is protected by copyright. All rights reserved.

In the current study, we analyzed the expression and function of sestrin1 (SESN1) in the aorta macrophages in a murine atherosclerosis model. We identified high SESN1 expression in the aorta macrophages in atherosclerotic mice. Using lentivirus-mediated SESN1 overexpression in macrophages, we found that SESN1 inhibited oxidized low-density lipoprotein (oxLDL)-induced NLRP3 inflammasome activation in lipopolysaccharide (LPS)-primed macrophages, as evidenced by less ASC-NLRP3 complex formation, lower Caspase-1 activation, and lower generation of mature IL-1β. Besides, SESN1 impeded oxLDL-induced activation of NK-κB signaling in macrophages. Furthermore, SESN1 suppressed cholesterol crystal-induced NLRP3 inflammasome activation and foam cell formation. Adoptive transfer of SESN1-overexpressing macrophages reduced the expression of pro-inflammatory cytokines in infiltrating macrophages and the whole aorta tissue. Adoptive transfer of SESN1-knockdown macrophages enhanced the expression of pro-inflammatory cytokines in infiltrating macrophages and the whole aorta tissue. Overall, our study sheds light on the significance of SESN1 for macrophage-mediated aorta inflammation. This article is protected by copyright. All rights reserved.

Functional aspects of padsevonil at the postsynaptic target, GABAA Rs, were characterized in experiments reported here. METHODS The effect of padsevonil on GABA-mediated Cl- currents was determined by patch clamp on recombinant human GABAA Rs (α1β2γ2) stably expressed in a CHO-K1 cell line and on native GABAA Rs in cultured rat primary cortical neurons. Padsevonil selectivity for GABAA R subtypes was evaluated using a two-electrode voltage clamp on recombinant human GABAA Rs (α1-5/β2/γ2) in Xenopus oocytes. RESULTS In recombinant GABAA Rs, padsevonil did not evoke Cl- currents in the absence of the agonist GABA. However, when co-administered with GABA at effective concentration (EC)20 , padsevonil potentiated GABA responses by 167% (EC50 138 nmpotential for tolerance development compared with classic benzodiazepines currently used in the clinic. © 2020 UCB Biopharma SRL.

Los esfuerzos para estimar el riesgo de desarrollar cáncer colorrectal (colorectal cancer, CCR) a lo largo de la vida en portadoras de mutaciones BRCA han dado resultados contradictorios. En consecuencia, no existen pautas formales con respecto a la necesidad de realizar el cribado de CRC en personas portadoras de mutaciones BRCA1 y/o BRCA2. Esta revisión sistemática y metaanálisis analiza el riesgo de CRC asociado en pacientes portadoras de mutaciones BRCA. MÉTODOS Se incluyeron nueve estudios en el metaanálisis. La población general del estudio fue de 18.839 pacientes, con 4.978 con CRC identificado. La variable principal fue la incidencia de cáncer colorrectal en portadoras de mutaciones BRCA. HOpic datasheet Las variables secundarias incluyeron el análisis de la incidencia de subgrupos en BRCA 1, BRCA 2, etnia judía Ashkenazi y cohortes emparejadas por edad y sexo. RESULTADOS No hubo un aumento de CRC en pacientes con una mutación BRCA (razón de oportunidades, odds ratio, OR 1,03; i.c. del 95% 0,80-1,32; P = 0,82). Cuando se ajustó de acuerdo con la ascendencia Ashkenazi y las estimaciones de edad y sexo, no hubo mayores probabilidades de desarrollar cáncer colorrectal (sin heterogeneidad en los estudios (I2 = 0)). CONCLUSIÓN Este metaanálisis concluye que el riesgo de cáncer colorrectal no fue significativamente mayor en las portadoras de mutaciones BRCA1 y/o BRCA2. Sin embargo, se requiere más evidencia antes de no recomendar la colonoscopia de cribado a las portadoras de la mutación BRCA1/2. Las pruebas de inmunoquímica fecal pueden ser una alternativa apropiada en esta población.DNA double-strand breaks (DSBs) are one of the most serious types of DNA damage. However, multiple repair pathways are present in cells to ensure rapid and appropriate repair of DSBs. Pathway selection depends on several factors including cell type, cell cycle phase, and damage severity. Ribosomal protein S3 (rpS3), a component of the 40S small ribosomal subunit, is a multi-functional protein primarily involved in protein synthesis. rpS3 is also involved in the mediation of various extra-ribosomal pathways, including DNA damage processing and the stress response. Here, we report that rpS3 is a novel negative regulator of non-homologous end joining (NHEJ)-mediated repair of DSBs. We found that rpS3 interacts with the Ku heterodimers of the DNA-dependent protein kinase (DNA-PK) complex and slows down NHEJ ligation reactions, ultimately triggering p53-dependent cell death following treatment with high-dose ionizing radiation. After DSB formation, DNA-PK phosphorylates rpS3, which consequently reduces the binding of rpS3 to the Ku complex.
