Ageing-related loss of proteostasis in ECs depends on Keap1, well-known repressor of Nrf2, recently perceived as a key independent regulator of EC function and protein S-nitrosation (SNO). Deposition of protein aggregates in ECs is associated with impaired autophagy. It can be counteracted by Keap1 depletion, S-nitrosothiol reductant or rapamycin treatment. Our results show that Keap1Nrf2 protein balance and Keap1-dependent SNO predominate Nrf2 transcriptional activity-driven mechanisms in governing proteostasis in ageing ECs.Drosophila has been extensively used to model the human blood-immune system, as both systems share many developmental and immune response mechanisms. However, while many human blood cell types have been identified, only three were found in flies plasmatocytes, crystal cells and lamellocytes. To better understand the complexity of fly blood system, we used single-cell RNA sequencing technology to generate comprehensive gene expression profiles for Drosophila circulating blood cells. In addition to the known cell types, we identified two new Drosophila blood cell types thanacytes and primocytes. Thanacytes, which express many stimulus response genes, are involved in distinct responses to different types of bacteria. Primocytes, which express cell fate commitment and signaling genes, appear to be involved in keeping stem cells in the circulating blood. Furthermore, our data revealed four novel plasmatocyte subtypes (Ppn+, CAH7+, Lsp+ and reservoir plasmatocytes), each with unique molecular identities and distinct predicted functions. We also identified cross-species markers from Drosophila hemocytes to human blood cells. Our analysis unveiled a more complex Drosophila blood system and broadened the scope of using Drosophila to model human blood system in development and disease.Although several scales have been designed to measure social capital, none have been specialized for caregivers of people with dementia, even though social capital is important in terms of continuing care provision. Therefore, we developed and validated a 17-item measure to assess social capital among caregivers of people with dementia. We assessed psychometric properties using responses from a questionnaire survey that included a draft of a social capital scale. Factor analysis identified three factors involving 17 items with a Cronbach's alpha of .85. The intra-class coefficient for test-retest reliability was .71. The correlation with positive aspects of caregiving was .62 (p less then .01). The results suggest that our scale could be a useful tool to assess social capital among caregivers of people with dementia.The prevalence of physician burnout among doctors of podiatric medicine (DPM) in the United States remains unknown. The purpose of the present pilot study was to assess perceptions of burnout, personal accomplishment, anxiety, and experiences of shame among DPMs training at Podiatric Medicine and Surgery Residency programs accredited by the Council on Podiatric Medical Education. An anonymous 35-question cross-sectional online survey was developed using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and the Hospital Anxiety and Depression Scale-Anxiety (HADS-A). Demographic data (sex, age, marital status, postgraduate year) and experiences of shame were also recorded. On December 31, 2018, the survey was distributed for completion. Univariate and bivariate analyses were conducted to obtain summary measures of the predictors and outcomes. Multinomial logistic regression models were obtained to evaluate the associations, and a 2-sided p less then .05 was considered statistically significant. A total of 155 responses were eligible for inclusion. Forty-six percent of respondents reported high burnout, and nearly half (54%) reported low personal achievement and moderate to severe anxiety. Most had experienced ≥1 shame event during residency, which was associated with a greater level of anxiety (p less then .001). Overall, lower burnout and higher personal achievement scores using the MBI-HSS were associated with lower anxiety scores using the HADS-A questionnaire (p less then .001) and the absence of an experienced shame event (p = .039). Given that a potential relationship appears to exist between anxiety/experiences of shame and burnout/personal achievement in the present pilot study, additional longitudinal studies are warranted to discern any causal relationships.The effects of class I antiarrhythmic drugs on the automaticity of isolated guinea pig pulmonary vein myocardia were investigated using microelectrode and voltage clamp methods. All of the drugs examined reduced the maximum rate of rise of automatic action potentials. The firing frequency and rate of diastolic depolarization were decreased by aprindine, flecainide and propafenone, but not by cibenzoline, disopyramide and pilsicainide, which correlated with blockade of the sodium current component induced by ramp depolarization mimicking the diastolic depolarization. In conclusion, class I antiarrhythmic drugs which block the diastolic sodium current component inhibit the automaticity of the pulmonary vein myocardium.Lymphangiogenesis is related to the growth of endometriosis. Selleckchem 740 Y-P Here, we examined whether vascular endothelial growth factor (VEGF) receptor 1 (VEGFR1) signaling plays a role in lymphangiogenesis during endometriosis. Endometrial fragments from wild-type (WT) mice transplanted into the peritoneal wall of host WT mice (WT→WT) developed well and displayed enhanced lymphangiogenesis associated with increases in mRNA levels of VEGF-C and VEGF-D. Compared with WT mice, the implant size and lymphangiogenesis were reduced, when endometrial fragments from mice lacking the VEGFR1 tyrosine kinase (TK) domain (TK-/-) were transplanted into host TK-/- mice (TK-/-→TK-/-). Treatment of WT→WT mice with the VEGFR3 kinase inhibitor suppressed the size of implants and lymphangiogenesis. Immunofluorescence analyses demonstrated that VEGF-C and VEGF-D were expressed in both CD11b+ and S100A4+ cells. TK-/-→TK-/- mice had lower numbers of CD11b+ and S100A4+ cells than WT→WT mice. When isolated bone marrow (BM)-derived macrophages or culture murine fibroblasts were stimulated with placental growth factor (PlGF), a specific agonist of VEGFR1, the levels of VEGF-C and VEGF-D were increased in a VEGFR1-dependent manner.
