Background: The most common type of apnea among premature newborns is idiopathic apnea of prematurity. Recurrent apnea can lead to hypoxemia and central nervous system damage. Although caffeine and theophylline are the most commonly prescribed drugs in this field, there is disagreement about which medicine is preferred. The purpose of this study was to compare the ther...

The purpose of this study was to examine: 1) whether caffeine in the fertilization medium under mineral oil is essential for bovine in vitro fertilization by fully capacitated spermatozoa, 2) the minimum concentration of caffeine that shows an adverse effect on the motility of preincubated spermatozoa. Cumulus-oocyte complexes with heterogeneous-appearing ooplasm were matured in in vitro cultur...

the effect of ephedrine at 0 (e0c0, n = 10), 8 (e8c0, n = 10) and 10 (e10c0, n = 10) mg per kg metabolic body weight or mixture of ephedrine/caffeine, at doses of 8 mg ephedrine/80 mg caffeine (e8c80, n = 10), or 10 mg ephedrine/100 mg caffeine (e10c100, n = 7), per kg metabolic body weight on body composition of feedlot mehraban ram lambs (8-month-old) was studied. the lambs were fed for 95 da...

Previous in vitro studies the have suggested anti-inflammatory properties of caffeine. Coffee is also rich phenolic acids with several potential health benefits (chlorogenic acids), mainly 5-caffeoylquinic acid (5-CQA). The aim present study was to determine effect caffeine and 5-CQA, using concentrations comparable typical human consumption, on LPS-induced cytokine production whole blood cultu...

background: caffeine increases the camp production that stimulates spermatozoa movement. caffeine is also used for induction of in vitro acrosome reaction in mammalian spermatozoa, an important step in achieving fertilization. objective: the aim of this study was to assess the effect of caffeine on sperm's motility, vitality and laboratory fertilization rates in mouse in two t6 and m16 media. m...

background: iranian (lahijan) black tea caffeine has been previously shown to have antifungal activity against candida albicans. the aim of this study was to investigate whether the combination of caffeine and fluconazole (flu) has an effective antifungal activity on a flu-resistant (mic >64mgl-1) c. albicans ptcc5027. materials and methods: caffeine from lahijan black tea was extracted and its...

the purpose of this study was to investigate the effect of caffeine ingestion on anaerobic power; fatigue index and blood lactate levels in boys athlete students. among voluntarers 16 subjects were selected and devided into two caffeine and placebo groups in a simple – randomized manner base on fatigue index in the pretest. they were asked to prevent from doing intensified activities 24 hours p...
