Metabolic acidosis has recently been observed in rat models of salt-sensitive genetic hypertension. To test the hypothesis that salt sensitivity in humans may be associated with abnormal acid-base homeostasis, we performed arterial blood gas analyses in young (20-31 years old) normotensive subjects (n = 40) who were placed on a low salt diet (20 mmol NaCl/day) for 2 weeks with either 200 mmol s...

to study some physiological and morphological traits of sugar beet varieties in response to salinity stress, three multi-germ sugar beets (13030, 22393 and ic) were grown in the greenhouse, faculty of agriculture, shahid chamran university, in 2009. the experiment was carried out under three levels of salinity in from of sodium chloride source, that included control (zero), 100 and 200 mm uses ...

Milk protein concentrate (MPC) is one of the major ingredients in foods due to its nutritional and functional properties including solubility, water binding, foaming, and emulsification. The foaming ability of milk proteins could potentially allow them to replace egg white protein; however, there is a lack of research on foaming properties of MPC. The goal of this study was to investigate the e...

Fifteen unselected patients who had essential hypertension and whose average supine blood pressure when they were not receiving any treatment and their usual sodium intake was 162/107 mm Hg were treated with captopril 50 mg twice daily. After one month's treatment their supine blood pressure had decreased to 149/94 mm Hg. They were then instructed to reduce their sodium intake to about 80 mmol(...

This study compares the involvement of ATP-sensitive potassium (K(ATP)) channels and prostaglandins in various forms of gastroprotection in the rat. Instillation of 1 ml of 70% ethanol induced severe gastric mucosal damage (lesion index 39 +/- 0.8), which was substantially but not maximally reduced by oral pretreatment with 16,16-dimethyl-prostaglandin (PG) E(2) (75 ng/kg), 20% ethanol (1 ml), ...

All recent methods for the isolation of the ribonucleic acids from yeast yield only 20 to 70 per cent of the ribonucleic acids that can be assumed to be present on the basis of quantitative analyses. There have been no studies regarding the nature of the ribonucleic acids that are lost during isolation, but it has tacitly been assumed that those which are lost have the same properties as those ...

Hybridization in 6xSSC (SSC, 0.15m-sodium chloride-0.015m-sodium citrate) at 66 degrees C was compared with hybridization in formamide-6xSSC (1:1, v/v) at 35 degrees C. As expected, the RNA hybridization potential was labile in the former system and stable in the latter. DNA retention by filters was poor in the formamide system, but could be improved. Several other properties of the hybridizati...

debaryomyces hansenizopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by ulocladium. chartarum(pr.) simm. the ability of d. hansenii to prevent infection of u. chartarum was lost when the antagonist cells were killed by autoclaving. cell free culture filtrates of antagonist were unable to prevent disease incidence. efficacy ...
