FOXO3a-dependent PARKIN negatively regulates cardiac hypertrophy by restoring mitophagy.

Background: Sustained cardiac hypertrophy often develops maladaptive myocardial remodeling, and eventually progresses to heart failure and sudden death. Therefore, maladaptive hypertrophy is considered as a critical therapeutic target for many heart diseases. Mitophagy, a crucial mechanism in mitochondria quality control and cellular homeostasis, has been implicated in diverse cardiac disorders such as myocardial infarction, diabetic cardiomyopathy, cardiac hypertrophy and heart failure.

Recent advances in photocatalytic polyfluoroarylation.

Polyfluoroaryl compounds belong to privileged moieties and engender distinct properties in many pharmaceuticals, agrochemicals, and materials. Over the past decade, considerable seminal reports and reviews have merely paid close attention to fluoroalkylation chemistry, such as trifluoromethylation, difluoroalkylation, perfluoroalkylation, trifluoromethylthiolation or trifluoromethoxylation. Polyfluoroarylation has inevitably lagged somewhat behind its fluoroalkylation counterparts, emanating from a lack of awareness and understanding of the synthetic significance.

Actor and Partner Effects of Touch: Touch-Induced Stress Alleviation Is Influenced by Perceived Relationship Quality of the Couple.

Because of the impact of close partner's touch on psychological and physical well-being by alleviating stress, it is important to explore the influence factors that underlie the stress-alleviating effect of close partner's touch. Previous studies suggested that the stress-alleviating effect was different when individuals were touched by different persons. Specifically, the stress was reduced significantly when the individual was touched by the close partner compared with the acquaintance and the stranger.
