it has been reported that cither lithium or verapamil can potentiate the neuromuscular blocking activity of certain neuromuscular blockers. in the present investigation, possible interaction of verapamil with lithium has been described. the dose ■ response effects of verapamil and lithium on diaphragmatic contractility were assessed in vitro. mechanical responses of the muscle to indirect (nerv...

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...

conclusion a significant relationship exists between the type of facial skeletal classification and the shape of the sella turcica; as in class iii patients, sella turcica bridge was reported with a higher frequency. also, sella turcica had a significantly higher length in these patients than in those with class i and class ii facial skeletal types. results sella turcica had normal morphology i...

fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...

retinoic acid (ra) plays a key role in pattern formation along the major body axis and limbformation during vertebrate development. exposure to excessive retinoic acid (in uterus) generatescongenital malformations in limbs, craniofacial, cns, urogenital, heart, and axial skeletons. in thesestudies, seven groups of nmri pregnant mice were administered a single gavage dose of 100 mg /kgbody weigh...

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: 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...
