backgroundsitting on inappropriate benches, as well as the poor posture (body position) during the years of growth, can lead to spinal disorders, fatigue and discomfort in students. this study aimed to investigate the relationship between features of desks and chairs and prevalence of some musculoskeletal disorders in primary school students in abadan.materials and methodsthis cross-sectional s...

background prediction of skeletal growth is necessary for growth modification and surgical orthodontic treatments and is usually done by assessing skeletal maturity indicators in hand-wrist radiographs. the use of growth stages of cervical vertebrae in lateral cephalograms has been suggested to avoid overexposure. objectives this study seeks to assess the degree of agreement between hand-wrist ...

skeletal muscle is a highly differentiated tissue with very specific functions which has low potential of regeneration. skeletal muscle injuries especially in athletes almost have lead to muscular dysfunctions and healing may be prolonged for several years. therefore, working on skeletal muscle differentiation remained an importance in biomedical researches. adipose derived stem cells (adscs) a...

In chronic heart failure (HF) from systolic cardiac dysfunction, the degree of exercise intolerance is not directly related to the degree of cardiac weakness.1–5 Somewhat surprisingly symptoms that typify HF, including shortness of breath and fatigue, are often directly related to the abnormalities of the skeletal musculature in HF. Our understanding of the features of skeletal myopathy is evol...

Bone serves as a multifunctional organ in avian species, giving structural integrity to the body, aiding locomotion and flight, regulating mineral homeostasis, supplementing calcium for eggshell formation. Furthermore, immune cells originate reside bone marrow, sharing milieu with cells, indicating potential interaction functions. In prevalence of gastrointestinal diseases can alter growth resp...
