there is strong evidence demonstrating that nifedipine dissolved in ethanol selectively inhibits only l-type ca2+ current. in addition, acute ethanol exposure reduces voltage-dependent calcium currents. in the present study, we investigated the antagonistic effect of fixed concentration of nifedipine dissolved in different concentration of ethanol on l-type ca2+ current. in a na+-k+ free soluti...

BACKGROUND Microorganisms can adapt to perturbations of the surrounding environment to grow. To analyze the adaptation process of the yeast Saccharomyces cerevisiae to a high ethanol concentration, repetitive cultivation was performed with a stepwise increase in the ethanol concentration in the culture medium. METHODOLOGY/PRINCIPAL FINDINGS First, a laboratory strain of S. cerevisiae was cult...

background: many studies have been done in order to interpret correctly the results of ethanol analysis and its related problems. unfortunately, it was not easy to determine bac rate, due to postmortem different conditions or personal and clinical differences in metabolism and excretion of ethanol. the time between death and autopsy, the environmental conditions (temperature and humidity) are i...

In oxygen-aerated non-growing cells a subinhibitory ethanol concentration (1 G/L) causes an H /K exchange. An inhibitory ethanol concentration (30 G/L) slows down acidification but + + has no effect on its extent. The transmembrane pH depends directly on the ethanol level in the medium and is not lowered at high ethanol concentrations. Changes in membrane potential induced by ethanol are also c...

To investigate the effect of ethanol on the zero-stress state of rabbit artery, a rabbit animal model of blood ethanol concentration gradient was established by intragastric administration of ethanol (IGAE). The blood ethanol concentration of each group was measured. The zero-stress state characterized by opening angle was observed by an image processing system. The results revealed that the bl...

lycopene is a natural and dominant pigment in tomato which today itsextraction enhancement from tomato and tomato products is trying. in this study atfirst wed use pectinase at 25, 30, 35 and 40 ml/kg concentration at 0, 30, 60, 90,120 and 180 effecting time in 55 0c constant temperature incubation. then beforeextraction half of samples were washed with 94% ethanol at 60 0c for 5 second. ithas ...

To evaluate the influence of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) on the ethanol fermentation process of Pichia pastoris GS115, this paper investigated the yeast growth, ethanol formation and the fermentable sugars consumption during the ethanol fermentation process of Pichia pastoris GS115 at different [Bmim]Cl concentrations in the medium. The results indicated that the [Bmim]Cl ha...

This paper discusses methods that will be used to experimentally determine the limitations of transdermal ethanol alcohol sensors when used on human subjects. Transdermal ethanol sensors are used to measure the concentration of ethanol emitted by the surface of the skin. The maximum concentration of ethanol in the skin is proportional to the concentration of ethanol in the blood stream but is o...
