We (1) evaluated the dose-dependent relationship between daily steps and disability in older adults with and without frailty and (2) examined the interaction between steps and frailty status in relation to the risk of disability. This prospective study used data from 4065 adults aged ≥ 65 years from the Kyoto-Kameoka Study, Japan.

GRK5 regulates endocytosis of FPR2 independent of β-Arrestins.

The formyl-peptide receptor 2 (FPR2) is a G-protein-coupled receptor (GPCR) that responds to pathogen-derived peptides and regulates both pro-inflammatory and pro-resolution cellular processes. While ligand selectivity and G-protein-signalling of FPR2 have been well characterized, molecular mechanisms controlling subsequent events such as endocytosis and recycling to the plasma membrane are less understood. Here we show the key role of the GPCR kinase 5 (GRK5) in facilitating FPR2 endocytosis and post-endocytic trafficking.

The storage quality and transcriptome analysis of fresh-cut taro by L-ascorbic acid combined with ultrasonic treatment.

Fresh-cut taro, renowned for its high nutritional value and convenience, is prone to rapid browning post-cutting, which hinders its storage life. This study focused on the effects of L-ascorbic acid (AA) combined with ultrasound (US) treatment (AS) on the storage quality and transcriptome analysis of fresh-cut slices of Yongding June Red Taro. Compared to the control (CK) group, AS treatment effectively reduced the weight loss rate of taro slices, maintained higher hardness, delayed the increase of browning, and inhibited the accumulation of O and HO.

Whole-Genome Metagenomic Analysis of Functional Profiles in the Fecal Microbiome of Farmed Sows with Different Reproductive Performances.

Recent studies suggested an association between the reproductive performance of sows and their gut microbiota. To understand how the gut microbiota affect the reproductive performances of sows, we conducted a whole-genome metagenomic analysis on the fecal microbial functional profiles of sows with high and low reproductive performances. We used 60 sows from six farms (10 sows/farm), including 30 sows from three farms with higher reproductive performances (the mean number of weaned piglets/sow/year) (group H) and 30 sows from three farms with lower performances (group L).
