Objective: To determine the relation between serum myostatin with body mass index (BMI) and PaO₂/PaCO₂ in men with chronic obstructive pulmonary disease (COPD).
Methods: A cohort of outpatients with stable COPD was evaluated. We evaluated the myostatin, PaO₂/PaCO₂ and BMI, and the patients were stratified by BMI. The plasma level of myostatin and PaO₂/PaCO₂ was measured by high sensitivity ELISA or blood gas analysis.
Results: PaCO₂ and myostatin increased significantly compared with those in the control group (P<0.05), but PaO₂ decreased significantly. There was positive correlation between myostatin and PaCO₂ (P<0.05), and negative correlation between myostatin and BMI/FEV1/pred value/PaO₂ (P<0.05).
Conclusion: Patients with higher myostatin levels had a lower BMI, lower PaO₂ and higher PaCO₂, with poor pathogenetic condition and prognosis. Myostatin may be a potential treatment target in patients with chronic obstructive pulmonary disease.

Background And Aims: Frailty is common among hemodialysis (HD) patients. Its assessment is usually based on clinical criteria. In the present work, we evaluated the interest of combining clinical frailty score and biomarkers to predict mortality of chronic HD patients.

Purpose: Obesity may blunt exercise responsiveness to improve muscular adaptations. The effect of resistance training (RT) targeting different body regions on muscle and inflammatory markers is unclear. This study aimed to investigate the impact of upper (upper body exercises), lower (lower body exercises), or combined (upper body + lower body exercises) RT on muscle and inflammatory markers, body composition, and performance in overweight and obese men.

Selective breeding is a potent method for developing strains with enhanced traits. This study compared the growth performance and stress responses of the genetically improved Abbassa Nile tilapia strain (G9; GIANT-G9) with a local commercial strain over 12 weeks, followed by exposure to stressors including high ammonia (10 mg TAN/L), elevated temperature (37 °C), and both for three days. The GIANT-G9 showed superior growth, including greater weight gain, final weight, length gain, specific growth rate, and protein efficiency ratio, as well as a lower feed conversion ratio and condition factor compared to the commercial strain.

Background: A decline in skeletal muscle mass and function known as skeletal muscle sarcopenia is an inevitable consequence of aging. Sarcopenia is a major cause of decreased muscle strength, physical frailty and increased muscle fatigability, contributing significantly to an increased risk of physical disability and functional dependence among the elderly. There remains a significant need for a novel therapy that can improve sarcopenia and related problems in aging.

Hip fractures are associated with high morbidity and mortality. Sarcopenia is a significant factor contributing to poor prognosis; however, the clinical diagnosis of sarcopenia remains difficult in surgical patients. This systematic review aims to identify the biomarkers of sarcopenia as diagnostic and predictive tools in patients admitted for hip fracture surgery.
