The relationship between sleep duration and frailty: findings from the China Health and Retirement Longitudinal Study.

Background: Research investigating the association between sleep duration and the risk of frailty has yielded conflicting results. This study used data from the China Health and Retirement Longitudinal Study (CHARLS) to investigate the association between sleep duration and frailty.

Methods: Participants aged 45 and above at baseline were included in this study.

Comparison of trans-umbilical single-port laparoscopic complete extraperitoneal closure and laparoscopic intracorporeal closure for pediatric inguinal hernia: a randomized controlled study.

Background: The purpose of this study was to compare the outcomes of Trans-umbilical single-port laparoscopic complete extraperitoneal closure (LCEC) and laparoscopic intracorporeal closure (LIC) for inguinal hernia by analysis of follow-up data over 5 years.

Methods: In this prospective randomized controlled trial, 524 children with inguinal hernia were randomly assigned to undergo LCEC or LIC between August 2016 and December 2017. The primary outcome measures were the success and recurrence rates.

Lysosomal reduced thiols are essential for mouse embryonic development.

While it has been appreciated for decades that lysosomes can import cysteine, its for organismal physiology is unclear. Recently, the MFSD12 transmembrane protein was shown to be necessary to import cysteine into lysosomes (and melanosomes), enabling the study of these processes using genetic tools. Here, we find that mice lacking die between embryonic days 10.

Crosslinking-mediated Interactome Analysis Identified PHD2-HIF1α Interaction Hotspots and the Role of PHD2 in Regulating Protein Neddylation.

Prolyl Hydroxylase Domain protein 2 (PHD2) targets Hypoxia Inducible Factor alpha subunits (HIFα) for oxygen-dependent proline hydroxylation that leads to subsequent ubiquitination and degradation of HIFα. In addition to HIF proteins, growing evidence suggested that PHD2 may exert its multifaceted function through hydroxylase-dependent or independent activities. Given the critical role of PHD2 in diverse biological processes, it is important to comprehensively identify potential PHD2 interacting proteins.

Associations of Combined Genetic and Lifestyle Risks with Incident Type 2 Diabetes in the UK Biobank.

Background: Type 2 diabetes (T2D) results from a complex interplay between genetic predisposition and lifestyle factors. Both genetic susceptibility and unhealthy lifestyle are known to be associated with elevated T2D risk. However, their combined effects on T2D risk are not well studied.
