in order to investigate factors affecting on seed germinating of london rocket (sisymbrium irio), lab experiments were set up in 2011 at the payamenoor university, mashhad, khorasan razavi province. effect of different concentrations of gibberellic acid (ga3) and cytokinin, wet and dry prechilling duration, hydrogen peroxide duration, ethanol, salt and osmotic stress and burial depth on seed ge...

To assess possible roles of atrial natriuretic factor (ANF) in the regulation of blood pressure in deoxycorticosterone acetate (DOCA)-salt hypertensive rats, we performed two series of experiments. First, we studied acute hypotensive, and natriuretic and diuretic effects of ANF in pentobarbital-anesthetized DOCA-salt hypertensive rats and age-matched controls. A synthetic rat ANF was intravenou...

It has been shown in the previous publications’ that the eriect of neutral salts on gelatin is repressed in the presence of the salt and that we can study such effects with any profit only when the excess of salt is washed away after it has had a chance to act on the protein. Such gelatin reveals qualities which are masked in the presence of the salt and which allow us to gain a clear insight i...

Heme oxygenase-1 (HO-1) is induced in the vasculature in the DOCA-salt model of hypertension in rats. Whereas the HO system and its products may exert vasodilator effects, recent studies have suggested that the HO system may predispose to hypertension. The present study examined the effects of selected components of the HO system, specifically, the HO-1 isozyme and the product bilirubin in the ...

The effect of salt concentration on catalysis by ribonuclease A (RNase A) has been reexamined. At low salt concentration, the enzyme is inhibited by low-level contaminants in common buffers. When an uncontaminated buffer system is used or H12A RNase A, an inactive variant, is added to absorb inhibitory contaminants, enzymatic activity is manifested fully at low salt concentration. Catalysis by ...

1. Extracts of urine were prepared from salt-depleted and salt-loaded subjects by gel filtration of freeze-dried urine on Sephadex G-50. The extracts were dissolved and adjusted to physiological pH and electrolyte concentration. 2. Separated renal tubule fragments were prepared from rabbit kidney cortex and their intracellular sodium and potassium measured after incubation in the dissolved adju...

in this study, the optimum combination of major factors affecting the acceptability of whey-based ricotta cheese i.e. fat at three levels (0, 5, 10%), salt at three levels (0, 1, 2%), and starter culture at two levels (0, 3%) was determined in a complete randomized design method with a factorial experiment. ricotta cheese trials made by mixing whey and milk in a ratio of 5:1 were then organ...

salinity stress is one of the most important abiotic stresses which threaten plants. in order to study the effect of salinity stress on yield and yield components of sunflower and also genetic analysis of these traits in relation with salt tolerance, a factorial experiment based on a completely randomized design with three replications was conducted. pots were arranged outside the greenhouse in...

The current public health recommendations are to reduce salt intake from 9 to 12 g/d to 5 to 6 g/d. However, these values are based on what is feasible rather than the maximum effect of salt reduction. In a meta-analysis of longer-term trials, we looked at the dose response between salt reduction and fall in blood pressure and compared this with 2 well-controlled studies of 3 different salt int...

Dietary salt restriction is one of the most important non pharmacological intervention in the management of hypertension and cardiovascular complications. In Chronic Kidney Disease (CKD) patients, observational and recent interventional studies investigating the relationship between sodium intake and renal outcomes suggest that low salt diet is warranted in this high risk category of patients. ...
