PURPOSE To determine the impact of amyotrophic lateral sclerosis (ALS) on the extraocular muscles (EOMs) by examining the laminin isoform composition of the basement membranes (BMs) in EOMs and limb muscles from donors with ALS. METHODS Muscle samples collected at autopsy from ALS donors and from transgenic mice overexpressing human superoxide dismutase type I mutations (D90A or G93A), and ag...

OBJECTIVE A loss of skeletal muscle mass is frequently observed in older adults. The aim of the study was to investigate the impact of type 2 diabetes on the changes in body composition, with particular interest in the skeletal muscle mass. RESEARCH DESIGN AND METHODS We examined total body composition with dual-energy X-ray absorptiometry annually for 6 years in 2,675 older adults. We also m...

BACKGROUND Whole body vibration (WBV) confers a continuous vibration stimuli to the body. While some reports have described the effects of WBV on bone mineral density, muscle mass, muscle power, study of WBV effects on body composition in postmenopausal women is rare. The aim of this pilot study was to examine the effect of WBV on the changes of body weight and body composition in postmenopausa...

Increased spontaneous locomotive activity and oxygen consumption have been reported in transgenic mice overexpressing leptin in the liver. In the present study, we examined whether the overexpression of leptin altered glycolytic and oxidative metabolic enzymatic activities as well as the composition of myosin heavy chain (MHC) isoforms in skeletal muscle. Enzymatic activities of lactate dehydro...

The sternocleidomastoid muscle (SCM) is one of the major muscles involved in producing abnormal head position in cervical dystonia patients. This study tested whether doxorubicin chemomyectomy, direct injection of doxorubicin into the SCM to permanently remove muscle fibers, has the potential to be a nonsurgical, permanent treatment for cervical dystonia. The right SCM of rabbits was injected w...

objective(s): pregabalin (pgb) is a new antiepileptic drug that has received fda approval for patient who suffers from central neuropathic pain, partial seizures, generalized anxiety disorder, fibromyalgia and sleep disorders. this study was undertaken to evaluate the possible adverse effects of pgb on the muscular system of mice. materials and methods: to evaluate the effect of pgb on skeletal...

In the present study, we identified free amino acid (FAA) contents and chemical composition in four populations of Salmo trutta macrostigma living in Mediterranean region of Turkey. In addition, taste impacts of FAAs were evaluated by taste active values. Moisture, protein, fat and ash content were found in the ranges of 75.49 - 79.59 %, 16.94 - 19.97 %, 1.58 - 3.75 % and, 1.39 - 1.56 %, respec...

The objective of the study was to compare Muscovy and Pekin ducks for proximate analysis, colour attributes, tenderness, meat microstructure, content some minerals in liver. material sexed 51 47 ducks. At end rearing period, 40 birds were selected dissection. Duck genotype influenced water, protein, fat, collagen, zinc, iron, haematin, redness, chroma, hue angle, WB shear force, muscle fibre di...

There is an increasing interest in including intramuscular fat (IMF) content and fatty acid composition, particularly oleic acid (C18:1) content, in the selection objectives of pig lines for quality pork markets. These traits are costly and can be measured in more than 1 location, so knowing their correlation structure across muscles and with subcutaneous fat (SF) is necessary for developing op...

We analyzed fiber type composition of soleus and extensor digitorum longus (EDL) muscles of 3- to 19-month-old male and female inbred Lewis rats using histochemical demonstration of mATPase activity. The rats were divided into four groups of the mean age of 3, 6, 9 and 14 months. We found that the soleus muscle of 3-month-old rats contained significantly more of fast 2A fibers and less of slow ...
