According to the commonly accepted membrane pump theory most of cellular K+ ions are freely dissolved in free cellular water; the alternative association-induction hypothesis postulates that the bulk of cellular K+ is adsorbed (weakly bound) to cellular proteins that are maintained in a specific labile state in the cytoplasm of a living cell. K+ activities measured with ion-sensitive microelect...

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...

purpose : to evaluate the results of anterior and nasal transposition (ant) of the inferior oblique muscle (io) in patients with the io muscle overaction methods : this retrospective case series included patients with io muscles overaction, in whom ant of the io muscle was performed. in patient with simultaneous horizontal deviation, horizontal strabismus surgery was also performed. they were e...

a bstract  background: pregnancy may be accompanied by serious physiological and psychological changes as it is a stressful period in a woman’s life. so, this study was conducted to determine the effect of progressive muscle relaxation on pregnant women’s general health.   materials and methods: in this clinical trial, 60 primigravida women admitted to the prenatal clinic of selected hospitals ...

inflammation and pain induced by delayed onset muscle soreness (doms) can be induced by eccentric exercise or an unaccustomed activity. the condition can causes problems in exercising and for athletes. the purpose of this study was to assess the effect of 150mg curcumin supplementation immediately after intensive eccentric exercise. evaluations were made for total antioxidant capacity (tac), mu...

Increasing plasma free fatty acids decreased the degree of glycogen depletion, and increased the citrate concentration, in slow-red (soleus) and fast-red (deep portion of vastus lateralis) muscle during exercise (approx. 50% depletion of glycogen, as against 75% in control animals). There was no effect in fast-white muscle (superficial portion of vastus lateralis). Glycogen concentration in the...

It has been extensively reported that free radical species are generated by contracting skeletal muscle following different exercise protocols (O’Neill et al. 1996; Reznick et al. 1996; McArdle et al. 2001), including non-damaging contractions (McArdle et al. 2001). However, numerous non-muscle cells are found in skeletal muscle in vivo and the presence of these cells has complicated the interp...

Successful obliteration of an empyema cavity with vascularized flaps can, on occasion, best be accomplished using a free tissue transfer. A conjoint free muscle flap captures the immunological attributes of muscle necessary in the infectious milieu of these defects, augments the potential flap volume required to fill these often large defects, yet relies on only a single recipient site for the ...
