OBJECTIVES This study tested the hypothesis that impairments in lower limb maximal strength and voluntary activation (VA) are exacerbated following match-play tennis in hot compared with cool conditions. METHODS Torque and VA were evaluated during brief (5 s) and sustained (20 s) maximal voluntary isometric contractions of the knee extensors (KE) and plantar flexors (PF) in 12 male tennis pla...

Background: Morphological changes of the cells infected with rubella virus cannot be observed easily. Estimation of the size of the cultured cells can be a valuable parameter in this condition. This study was conducted to find answers to the following questions:How much time after infection with rubella virus, the volume and surface area of the Vero cells and their nuclei get started to change?...

osteonectin is a bone- associated protein involved in vascular calcification. adiponectin may protect against cardiovascular disease but possible effects on vascular calcification have been poorly studied. the aim of this study was to investigate the modulatory effect of adiponectin on oxidized low density lipoprotein (oxldl)- induced expression of osteonectin in human aorta vascular smooth mus...

Objective: Jaundice is a common problem in infants, particularly premature infants (60-80%). The most common treatment of neonatal jaundice is phototherapy; however, traditional and complementary medicine is preferred due to complications of phototherapy in newborns. This study evaluates the effect of Chicory extract bath on bilirubin levels of infants with jaundice hospitalized in educational ...

AIM To explore the relationship between alteration in the expression of TWIST, highly conserved transcription factor from the basic helix-loop-helix family, and apoptosis of Hep-2 cells induced by chemotherapeutic agent paclitaxel. METHODS Morphological changes of Hep-2 cells were observed by acridine orange cytochemistry staining. Viability of Hep-2 cells treated with various concentrations ...

simple and corresponding impacts of adding acidic improvers (lactic acid , acetic acid and citric acid ) on bread staling has been researched twice in 3 levels( 0%, 0.25 % and 0.5 %) by factorial experimental method .there was an orthogonal comparison between the two treatments (acidified treatments and sourdough groups) in the second stage. the effect of lactic acid on bread staling was signif...

the purpose of this study was to examine the effect of indomethacin on biochemical, functional and external symptoms of delayed onset muscle soreness (doms) following eccentric exercise. for this purpose, 20 untrained, healthy male volunteers (age 25.8+6.9 years and fat 15.9+9.3 %) were selected and randomly divided into experimental (n=10) and placebo (n=10) groups. in a double blind study, su...
