HBx localized to the mitochondria, where it induced mitochondrial damage and production of mitochondrial reactive oxygen species (mitoROS). Treatment of HL7702 cells with a mitoROS scavenger attenuated HBx-induced NLRP3 activation and pyroptosis. Expression levels of NLRP3, ASC, and IL-1β in liver tissues from patients were positively correlated with HBV DNA concentration. CONCLUSIONS The NLRP3 inflammasome was activated by elevated mitoROS levels and mediated HBx-induced liver inflammation and hepatocellular pyroptosis under H2O2-stress conditions.OBJECTIVES This study (1) estimated the association between experienced sex work-related stigma and moderate-to-severe depressive symptoms (hereafter depression), (2) examined independent associations between internalized stigma, experienced stigma, and depression among sex workers, and (3) investigated the potential modifying role of social support. METHODS A cross-sectional survey was conducted among 729 male and female sex workers in Kenya. RESULTS The prevalence of depression was 33.9%, and nearly all participants reported at least one of the experienced and internalized stigma items. Increasing levels of experienced stigma was associated with an increased predicted prevalence of depression [aPD 0.15 (95% CI 0.11-0.18)]. Increasing internalized stigma was independently associated with higher experienced stigma and depression and appeared to account for 25.5% of the shared variance between experienced stigma and depression after adjustment for confounders. Social support from same-sex sex workers did not appear to modify the association between experienced stigma and depression. CONCLUSIONS Addressing the high levels of stigma that sex workers face and their mental health needs should be a public health and human rights imperative.Pediatric human immunodeficiency virus post-exposure prophylaxis is frequently indicated, but delays in medication receipt are common. Using plan-do-study-act cycles, we developed a multidisciplinary collaboration to reduce critical process delays in our pediatric emergency department. Interruptions decreased from a median 1 per month pre-intervention to zero per month during the intervention. © The Author(s) 2020.

It has been reported that elevated fibroblast growth factor (FGF)-23, increased serum soluble α-klotho, and decreased vitamin D3 are associated with cancer progression. We studied the relationship between shift work and the levels of FGF-23, klotho, and vitamin D3 amongst firefighters, as they work in long shifts outside the traditional daytime schedule. METHODS The study consisted of 450 participants who were firefighters. We measured FGF-23, α-klotho, and vitamin D3 levels in their blood and a set of questionnaires was given to the subjects to evaluate their health habits. After determining and adjusting for potential confounding factors, we compared the levels of FGF-23, klotho, and serum vitamin D3 by job and shift types. RESULTS FGF-23 and α-klotho levels were significantly higher in shift workers than traditional day workers, and in 3-day cycle shift workers than workers with another shift schedule. When the levels of these substances were compared based on different types of jobs, firefighters had a lower level of vitamin D3. We conclude that shift work is positively correlated with the levels of FGF-23 and klotho. CONCLUSION Levels of FGF-23 and α-klotho were linked to shift work and job types. Although vitamin levels did not differ by shift types, vitamin D3 levels were lower in firefighters. These findings suggest that high levels of FGF-23 and α-klotho are potential risk factors for cancer among firefighters. © Sleep Research Society 2020.

In vitro and in silico models of this process demonstrate a random pattern of sulci and gyri, unlike the highly ordered and conserved structure seen in the human cortex. Here, we account for the large-scale pattern of cortical folding by combining advanced fetal magnetic resonance imaging with nonlinear diffeomorphic registration and volumetric analysis. Our analysis demonstrates that in utero brain growth follows a logistic curve, in the absence of an external volume constraint. The Sylvian fissure forms from interlobar folding, where separate lobes overgrow and close an existing subarachnoid space. see more In contrast, other large sulci, which are the ones represented in existing models, fold through an invagination of a flat surface, a mechanistically different process. Cortical folding is driven by multiple spatially and temporally different mechanisms; therefore regionally distinct biological process may be responsible for the global geometry of the adult brain. © The Author(s) 2020.

This system is involved in the modulation of essential physiological processes. Its role in the reproductive system has become significantly important in recent years, given its major role in events such as gametogenesis, decidualisation, implantation and placentation. OBJECTIVE AND RATIONALE In this paper, we review the literature and summarize the role of the ECS elements in reproduction and their potential as early markers for diagnosis of reproductive disorders or as pharmacological targets for treatment. SEARCH METHODS Original research and review papers published from 1964 to June 2019 were selected in terms of relevance, reliability and quality by searching PubMed, MEDLINE and Web of Science, using the following search terms endocannabinoid system and endometriosis; endocannabinoid system and ectopic pregnancy; endocannabinoid system and miscarriage; endocannabinoid system and pre-eclampsia; endocannabinoid system and endometrial cancer; endocannabinoid system and reproduction; endocannabinoid, endometrium; placenta; N-acylethanolamines; anandamide; 2-arachidonoylglycerol; and cannabinoids.
