Succinate Regulates Exercise-Induced Muscle Remodelling by Boosting Satellite Cell Differentiation Through Succinate Receptor 1.

Background: Skeletal muscle remodelling can cause clinically important changes in muscle phenotypes. Satellite cells (SCs) myogenic potential underlies the maintenance of muscle plasticity. Accumulating evidence shows the importance of succinate in muscle metabolism and function.

Predictive value of serum fibroblast growth factor 19 and liver stiffness for intestinal failure associated liver disease-cholestasis.

Background: Intestinal failure associated liver disease (IFALD)-cholestasis is a common complication of long-term parenteral nutrition (PN) in patients with intestinal failure (IF). The lack of effective early identification indicators often results in poor clinical outcomes. The objective of this study was to evaluate the predictive value of serum FGF19 and liver stiffness in IFALD-cholestasis.

Effects of resistance training on sarcopenia in patients with intestinal failure: A randomized controlled trial.

Background: The potential effects of resistance training on sarcopenia in patients with intestinal failure (IF) are not fully elucidated. This study aimed to explore the efficacy of a resistance training program on appendicular skeletal muscle index (ASMI), physical performance, body composition, biochemical parameters, and health-related quality of life (HRQOL) in patients with IF exhibiting sarcopenia.

Methods: A single-center randomized controlled trial was conducted in a Chinese tertiary teaching hospital.

Total parenteral nutrition impairs glucose metabolism by modifying the gut microbiome.

Total parenteral nutrition (TPN) can lead to complications, such as glucose metabolism disorders. While TPN is associated with impairments in intestinal function, the gut barrier and mucosal immunity, the relationship between the gut microbiome and TPN-related glucose metabolism disorders remains to be explored. In a cohort of 256 participants with type 2 intestinal failure, we show that parenteral nutrition providing >80% of total energy induces insulin resistance and a higher risk of complications.

Down regulation of NDUFS1 is involved in the progression of parenteral-nutrition-associated liver disease by increasing Oxidative stress.

Parenteral nutrition (PN)-associated liver disease (PNALD) is a common and life-threatening complication of patients receiving PN. However, its definitive pathology remains unclear. Ubiquinone oxidoreductase core subunit S1 (NDUFS1), which is the largest core subunit of mitochondrial complex I, could alter the mitochondrial reactive oxygen species (ROS) formation.

Liver PP2A-Cα Protects From Parenteral Nutrition-associated Hepatic Steatosis.

Background & Aims: Parenteral nutrition (PN) is a lifesaving therapy for patients with intestinal failure. Hepatic steatosis is a potentially fatal complication of long-term PN, but the involved pathological mechanisms are incompletely unclarified. Herein, we identify the role of protein phosphatase 2A (PP2A) in the pathogenesis of parenteral nutrition-associated hepatic steatosis (PNAHS).

Multi-Omics Analyses Characterize the Gut Microbiome and Metabolome Signatures of Soldiers Under Sustained Military Training.

Exercise can directly alter the gut microbiome at the compositional and functional metabolic levels, which in turn may beneficially influence physical performance. However, data how the gut microbiome and fecal metabolome change, and how they interact in soldiers who commonly undergo sustained military training are limited. To address this issue, we first performed 16S rRNA sequencing to assess the gut microbial community patterns in a cohort of 80 soldiers separated into elite soldiers (ES, = 40) and non-elite soldiers (N-ES, = 40).
