Exercise training ameliorates high-fat diet-induced skeletal muscle atrophy and ferroptosis via downregulation of STING.

Background: High-fat diet (HFD)-induced sarcopenic obesity can lead to reductions in muscle fiber diameter, enhanced protein degradation, and various forms of cell death. Exercise training has been shown to alleviate HFD-induced muscle atrophy. However, the underlying mechanism remains unclear.

Lipid droplets: Emerging therapeutic targets for age-related metabolic diseases.

Lipids metabolism is crucial in regulating aging and metabolic diseases. Lipid droplets (LDs) are dynamic, complex organelles responsible for the storage and release of neutral lipids, essential for maintaining lipid homeostasis and energy metabolism. Aging accelerates the accumulation of LDs, functional deterioration, and metabolic disorders, thereby inducing age-related metabolic diseases (ARMDs).

Aerobic Exercise Activates Fibroblast Growth Factor 21 and Alleviates Cardiac Ischemia/Reperfusion-induced Neuronal Oxidative Stress and Ferroptosis in Paraventricular Nucleus.

Cardiac ischemia/reperfusion (I/R) induces systemic oxidative stress, which in turn gives rise to the development of multiple organ abnormalities, including brain injury. The paraventricular nucleus (PVN) of the hypothalamus is a cardiovascular regulatory center. Aerobic exercise is an effective intervention to protect the heart against I/R injury.

Role of Irisin in exercise training-regulated endoplasmic reticulum stress, autophagy and myogenesis in the skeletal muscle after myocardial infarction.

Patients with heart failure (HF) are often accompanied by skeletal muscle abnormalities, which can lead to exercise intolerance and compromise daily activities. Irisin, an exercise training (ET) -induced myokine, regulates energy metabolism and skeletal muscle homeostasis. However, the precise role of Irisin in the benefits of ET on inhibiting skeletal muscle atrophy, particularly on endoplasmic reticulum (ER) stress, autophagy, and myogenesis following myocardial infarction (MI) remains unclear.

ELABELA-APJ-Akt/YAP Signaling Axis: A Novel Mechanism of Aerobic Exercise in Cardioprotection of Myocardial Infarction Rats.

Purpose: The aim of this study was to investigate the function and mechanisms of ELABELA (ELA) in the aerobic exercise-induced antiapoptosis and angiogenesis of ischemic heart.

Methods: The myocardial infarction (MI) model of Sprague-Dawley rat was established by the ligation of the left anterior descending coronary artery. MI rats underwent 5 wk of Fc-ELA-21 subcutaneous injection and aerobic exercise training using a motorized rodent treadmill.

The clinical application of metagenomic next-generation sequencing in infectious diseases at a tertiary hospital in China.

Background: Compared with traditional diagnostic methods (TDMs), rapid diagnostic methods for infectious diseases (IDs) are urgently needed. Metagenomic next-generation sequencing (mNGS) has emerged as a promising diagnostic technology for clinical infections.

Methods: This retrospective observational study was performed at a tertiary hospital in China between May 2019 and August 2022.

Irisin and ALCAT1 mediated aerobic exercise-alleviated oxidative stress and apoptosis in skeletal muscle of mice with myocardial infarction.

Skeletal muscle in patients with heart failure (HF) exhibits altered structure, function and metabolism. Myocardial infarction (MI) is the most common cause of HF. Oxidative stress and cell apoptosis are involved in the pathophysiology of MI/HF-induced skeletal muscle atrophy.

A comprehensive analysis of the microbiota composition and host driver gene mutations in colorectal cancer.

Studies of both, microbiota and target therapy associated with gene mutations in colorectal cancer, (CRC) have attracted increasing attention. However, only a few of them analyzed the combined effects on CRC. we analyzed differences in intestinal microbiota of 44 colorectal cancer patients and 20 healthy controls (HC) using 16S rRNA gene sequencing of fecal samples.

Strigolactones affect the translocation of nitrogen in rice.

Strigolactones (SLs) are involved in the nutrient-dependent control of plant root and shoot architecture. The total sufficient uptake of nitrogen (N), and also its appropriate distribution, is essential for the normal growth and development of plants; however, the effect of SLs on N translocation in plants remains unknown. Here, the SL-signaling mutant dwarf 3 (d3), the biosynthesis mutant dwarf 10 (d10), and wild-type (WT) rice (Oryza sativa ssp.
