A 60-days feeding trial was conducted to study the effect of higher temperature (32°C) in comparison to ambient temperature (24.5°C) on different metabolic enzyme namely, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adenosine triphosphatase (ATPase), acid phosphatase (ACP) & alkaline phosphatase (ALP) activities in different tissues of Pangasianodon hypophthalmus. AST activ...
Objective Numerous abdominal exercises with Swiss ball are used to improve core stability with strengthening and rehabilitation goals. It is claimed that the stability exercises have a greater impact on core muscle activation, but the validity of this claim is still in doubt. Moreover, there is no comprehensive study on the comparison of the core muscles activity in different core stability exe...
Objective: This study aimed to investigate the effects of leg positioning on the activity of shoulders and body while lifting weights. Methods: Employing an electromyography set (BTS free EMG 300) and surface electrodes, the activity of such muscles as biceps, triceps, anterior, medial and posterior deltoid, trapezius and erector spinae, while lifting a weight weighing %15 of body mass, in thr...
Purpose: The purpose of this study was to compare the effects of two different approaches of dual-task training and executive training on lower limb muscular activity in older adults with balance impairment. Methods: This was a quasi-experimental study performed with the pre-test and post-test method. Thirty older adults (age= 73.8±4.6, height= 1.65±0.06, weight= 69.17±12.67) were randomly ass...
Background & Aims: Scoliosis is linked with asymmetrical compression loads induced by trunk muscles and external loads. The objective of this study was to measure the electrical activity of bilateral erector spinae muscles during the rest in the standing, sitting and lying positions. Materials & Methods: Ten patients with double curvature (right thoracic and left lumbar) scoliosis...
A recent study describing unique effects of myostatin inhibition on a severely dystrophic (mdx) muscle, and independent experiments showing that branched fibers are uniquely sensitive to activity-induced membrane rupture, have led new hypothesis pathogenesis. This states the absence dystrophin directly results in some degree unrestrained satellite cell activation is not dependent upon prior fib...
background: n-acetylcysteine (nac) has been indicated against experimental seizures, but with relatively inconclusive results. this study was undertaken to evaluate whether nac exerts a dose-dependent anticonvulsant effect and to determine nac safe therapeutic dose range and its muscle-relaxant activity in both acute and chronic uses. methods: following intraperitoneal (i.p.) administration of ...
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,...
