background : muscle cramps are painful manifestations that occur in many cirrhotic patients. this study aims to evaluate the risk factors for developing muscle cramps. materials and methods: this cross-sectional study evaluated 24 cirrhotic patients (18 male, 6 female) during 15 months. patients underwent careful examinations administered by the same person to determine the underlying cause of ...

introduction: satellite cells are known as the main regenerative cell type in skeletal muscles. our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. me...

background :falls have been strongly associated with decreased physical activity and impaired mobility. reduced range of motion, as a consequence of muscle stiffness, has been indicated to assume a positive relationship to fall incidence. also clinical observations suggest that maintaining the normal spinal curves is associated with the prevention of spinal, knee and hip disorders. thus, the ai...

this study aimed to investigate the effects of different doses of sulfadiazine on embryonic chicken pectoral muscles. in total, 100 fertile eggs were obtained and divided into five groups of control (no injection) and sulfadiazine injection at doses of 2, 10, 30, and 70 mg/kg. after hatching, pectoral muscle tissues were harvested from the newly hatched chickens for histopathological examinatio...

background: interferons (ifns) are common therapeutics for several diseases such as viral hepatitis, multiple sclerosis and malignancy. a variety of autoimmune related side effects have been observed during ifn therapy. rare cases of myopathy, polymyositis or dermatomyositis have been reported during therapy with high doses of ifn^5. case presentation: in this report, we describe a case with se...

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...

background: the purpose of present study was to investigate whether sphingosine 1-phosphate (s1p) levels and its receptors gene expressions are correlated with myod and myogenin following resistance training. materials and methods: 24 eight-week-old male wistar rats (190-250 gr) were assigned randomly to a control (n = 12) or training (n = 12) group. rats climbed a resistance training ladder wi...

spinal muscular atrophies (smas) represent a rare group of inherited disorders that cause progressive degeneration of the anterior horn cells of the spinal cord. the exact cause of the degeneration is unknown. loss of these cells results in a progressive lower motor neuron disease that has no sensory involvement and that is manifested as hypotonia, weakness, and progressive paralysis. kugelberg...

the possibility of in vivo carcass trait prediction using the ultrasound measurements obtained between 12th and 13th ribs was studied. attention was paid to several carcass traits such as carcass backfat thickness (cbft), carcass longissimus dorsi muscle (clma) and carcass weight (hcw). also, the effects of the flock, as the fixed effects, and body weight (bw), as covariate, on these traits wer...

objective(s): previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. the aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. materials and methods: four weeks after surgeries (left anterior descending (lad) artery occlusion), chr...
