vitamin d deficiency is a worldwide epidemic, with well known impacts on calcium metabolism and bone health, but increasingly recognized associations with chronic health problems such as bowel and colonic cancer, arthritis, diabetes and cardiovascular disease. in recent years in the sports medicine literature, there has been an increased focus on the potential impact that inadequate vitamin d l...

Objective(s): The purpose of this study is to investigate the indication function of the calcium circulation-related factors on the damage to muscle strength and contraction function after nerve injury. The target factors include ryanodine receptor (RyR), inositol-1,4,5-triphosphate receptor (IP3R), phospholamban (PLN), cryptocalcitonin (CASQ), ATPase and troponin C (T...

Background: Conservative management is generally the primary treatment for intramuscular hemangimas. However,many patients will require surgery later in their life, after suffering a long period of pain. We aimed to evaluate theoncologic and functional outcomes of surgery as the initial treatment of single-muscle hemangiomas.Methods: Medical profiles of 17 patients with hemang...

abstract background: chronic obstructive pulmonary disease (copd) is currently the fourth cause of mortality worldwide. patients with copd experience periods of dyspnea, fatigue, and disability, which impact on their life. the objective of this study was to investigate the effect of short‑term inspiratory muscle training on exercise capacity, exertional dyspnea, and pulmonary lung function. mat...

background: it is widely recognized that neuromuscular function is temperature sensitive. changes in muscle temperature may affect muscle force development. the aim of this study was to investigate the effects of temperature on wrist flexor muscles endurance. methods: fifteen healthy subjects (mean age  21.13 ±1.30 years) participated in the present study.  the wrist flexor muscles endurance wa...

objective(s):in this study, we aimed at evaluation of electrophysiological and histopathalogical characteristics of statin-induced muscle injury as well as clinical features of patients who develop this condition in terms of frequency and pattern of evolution. materials and methods: forty patients (age 39-74 years) including 25 subjects with type 2 diabetes mellitus, 9 with cardiovascular disea...

the reliability of surface electromyographic (semg) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. this study aimed to establish the reliability of the semg measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. two groups of volunteers (24 older adults,...
