on.Purpose Citrate has a positive effect on improving the pathophysiological changes of cardiomyocytes such as cardiac failure and auricular fibrillation. However, the underlying mechanism remains still unclear.Methods Rat cardiomyocytes were used to establish hypoxia/reoxygenation (H/R) cell model. Citrate was conduct to pretreat with cardiomyocytes, and microRNA-142-3p (miR-142-3p) knockdown and overexpression were used to determine the underlying mechanism of their functions in cardiomyocytes. Cell viability and apoptosis were respectively detected by CCK-8 and flow cytometry. Protein and mRNA levels were determined by Western blot and qRT-PCR. Luciferase reporter assay and Targetscan were performed to study the regulation of miR-142-3p and Rac1.Results The level of miR-142-3p was down-regulated in H/R model, but up-regulated in cardiomyocytes following citrate treatment. Citrates attenuated H/R injury induced miR-142-3p level and cell viability, and also inhibited H/R injury induced apoptosis, LDH, MDA and autophagy. Cell viability was improved, and autophagy was suppressed by miR-142-3p mimic, while inhibitor had opposite results. Compared with H/R + miR-142-3p inhibitor group, cell viability was higher, and apoptosis and autophagy were lower in Cit + H/R + miR-142-3p inhibitor group. Furthermore, Rac1 was target gene of miR-142-3p, and decreased by citrate, in comparison with H/R + miR-142-3p inhibitor group.Conclusion Taken together, our findings indicated that citrate ameliorates H/R injury-induced cardiomyocytes autophagy by regulating miR-142-3p/Rac1 aix.Objective We aimed to examine whether variability in high-density lipoprotein cholesterol (HDL-c) over time was associated with cognitive function. Method We conducted a post hoc analysis of the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER) trial. Our sample included 4,428 participants with at least two repeated HDL-c measures between Months 3 and 24 postbaseline and with cognitive assessments at Month 30. HDL-c variability was defined as the intraindividual standard deviation over each person's repeated measurements. Results Higher HDL-c variability was associated with worse performance on the Letter-Digit Coding Test (β [95% confidence interval] [CI] = -4.39 [-7.36, -1.43], p = .004), immediate recall on the 15-Picture Learning Test (β [95% CI] = -0.98 [-1.86, -0.11], p = .027), and delayed recall on the 15-Picture Learning Test (β [95% CI] = -1.90 [-3.14, -0.67], p = .002). The associations did not vary by treatment group. Discussion Our findings suggest that variability in HDL-c may be associated with poor cognitive function among older adults.Objectives The beneficial effects of testosterone replacement therapy (TRT) in men with late-onset hypogonadism (LOH) on the body composition and metabolic outcomes are well-established. A potential explanation might lie in the hormones, secreted from skeletal muscles, named "myokines". The aim of this study was to evaluate the effects of TRT on the levels of serum irisin in subjects with LOH.Study Design A total 40 men with metabolic syndrome (MS) and LOH (measured serum testosterone concentration less then 12 nmol/l). TRT with Testosterone Undecanoate (Nebido™) was performed at baseline and at week 6. selleck chemicals llc Irisin serum concentration was determined at baseline and at week 18 by means of ELISA.Results Circulating irisin was positively associated with serum testosterone (r = 0.283, p less then 0.05). TRT has led to a statistically significant rise in circulating serum irisin levels (7.12 ± 0.76 mcg/ml versus 7.76 ± 0.75 mcg/ml; paired-samples t-test p less then 0.001). ROC-analyses determined irisin to be predictive of treatment response (AUC = 0.741, p = 0.014).Conclusions Irisin is positively associated with serum testosterone in a population of men with MS and LOH. TRT in these subjects has led to a significant improvement in associated clinical symptoms as well as to a significant rise in serum irisin levels.Objective The main objective was to develop a decision-support tool to assess the risk of caregiver burden, the Caregiver Risk Evaluation (CaRE) algorithm. Methods Home care clients were assessed using the Resident Assessment Instrument for Home Care (RAI-HC). Their caregiver completed the 12-item Zarit Burden Interview (ZBI), the main dependent measure, which was linked to the RAI-HC. Results In the sample (n = 344), 48% were aged 85+ years and 61.6% were female. The algorithm can be collapsed into four categories (low, moderate, high, and very high risk). Relative to the low-risk group, clients in the very high-risk group had an odds ratio of 5.16 (95% confidence interval [2.05, 12.9]) for long-term care admission, after adjusting for client age, sex, and regional health authority. Discussion The CaRE algorithm represents a new tool to be used by home care clinicians as they proactively plan for the needs of clients and their caregivers.Few empirical studies have been conducted on populations in the Middle-East, particularly in Iraq and Iraqi Kurdistan, regarding the relationships between the type of discipline used by caregivers and its subsequent effect on children. Our analyses, which are based on data from the Iraq Multi-Cluster Survey 2018, replicate the prior work of scholars using Western samples, and suggest that variation in parental practices pertaining to the discipline of children is a robust predictor of several negative psychosocial outcomes among Iraqi and Kurdish youth. Specifically, we found that children who were subjected to various forms of violent physical discipline, psychological aggression, and neglectful parenting were more likely to exhibit an array of symptoms of psychosocial disorder, relative to measures of adequate parenting. Our analyses also provide strong support for the presence of comorbid psychosocial outcomes among Iraqi and Kurdish youth that stem from differences in the practice of parental discipline. The results of the current study are discussed regarding both theoretical and practical applications. The study's limitations are also addressed and suggestions for future research on the discipline-outcome nexus are given.
