Involuntary physical activity induced by the avoidance of electrical shock leads to improved endurance exercise capacity in animals. However, it remains unknown whether voluntary stand-up physical activity (SPA) without forced simulating factors improves endurance exercise capacity in animals. We examined the eff ects of SPA on body weight, cardiac function, and endurance exercise capacity for ...

BACKGROUND Irisin, an exercise-induced myokine, is closely correlated with obesity and body mass index. Obesity is one risk factor of coronary artery disease (CAD). Therefore, the present study aimed to determine if serum irisin concentrations are correlated with the presence and severity of CAD. MATERIAL AND METHODS Serum irisin concentrations were determined in 350 patients with CAD and in 21...

Background We examined the effect of antioxidant supplementation and exercise on irisin within postmenopausal women. Methods Forty-eight participants (age: 55.7 ± 4.9 years; weight: 68.0 ± 6.3 kg; BMI 27.0 ± 2.7; mean ± SD) were randomized into four groups for the eight week intervention: control group (CG; n = 12), resistance training group (RTG; n = 12), supplementation with Zataria multifl...

OBJECTIVE To model the potential interaction between previously identified biomarkers in children sarcomas using artificial neural network inference (ANNI). METHOD To concisely demonstrate the biological interactions between correlated genes in an interaction network map, only 2 types of sarcomas in the children small round blue cell tumors (SRBCTs) dataset are discussed in this paper. A back...

The epidemic of obesity has contributed to the rapid rise in comorbid conditions such as cardiovascular disease, type 2 diabetes, sleep apnea, and hypertension among others. Therefore, there is a critical need to develop therapeutic strategies to reduce the prevalence of the disease. Skeletal muscle cells secrete signaling cytokines/peptides (referred to as myokines) that act in autocrine, para...

Irisin is a myokine encoded in its precursor fibronectin type III domain containing 5 (FNDC5). It is abundantly expressed in cardiac and skeletal muscle, and is secreted upon the activation of peroxisome proliferator-activated receptor gamma coactivator-1 (PGC-1 alpha). We aimed to study the role of irisin on cardiac function and muscle protein regulation in zebrafish. Western blot analyses det...

Myokines are peptides produced and secreted by the skeletal muscle, with autocrine, paracrine, and endocrine actions. Many of them are overexpressed during physical exercise and appear to contribute to the benefits of exercise to metabolic homeostasis. Irisin, resulting from the cleavage of the membrane protein FNDC5, was shown to induce adipocyte browning, with increased lipid oxidation and th...

Irisin is a hormone-like myokine produced in abundance by skeletal muscle in response to exercise, both in mice and humans. Once released into the circulation, irisin acts on white adipocytes to induce the browning response and subsequently activates nonshivering thermogenesis. We have examined the premise that irisin produced during exercise may subserve further functions in the musculoskeleta...
