It is well-known that evaporation of sessile drops with suspended particles like colloids and coffee powders can yield a variety of two-dimensional patterns depending on the particle shapes and internal flow patterns. Here we show that ordered three-dimensional structures can be built via evaporation of saline drops on highly hydrophobic substrates like pristine PP (polypropylene) with micropor...

This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...

11 beta-Hydroxysteroid dehydrogenase (11 beta-HSD) modulates the access of corticosteroids to their receptors and plays an important role in controlling blood pressure. We determined 11 beta-HSD activity and mRNA levels in the mesenteric arteries of genetically hypertensive rats, the Dahl salt-sensitive hypertensive rat, and compared them with Dahl salt-resistant and Sprague-Dawley rats. 11 bet...

Salinity affects normal growth and development of plants depending on their capacity to overcome the induced stress. The present study was focused on the response and regulation of the antioxidant defence system in Brassica oleracea roots under short and long salt treatments. The function and the implications of hydrogen peroxide as a stressor or as a signalling molecule were also studied. Two ...

In order to get the high liquefaction yield from marine algae cell mass to fuel oil, the effect of salt stress on the accumulation of lipids and triacylglyceride in Dunaliella cells was investigated. Although initial NaCl concentration higher than 1.5 M markedly inhibited cell growth, increase of initial NaCl concentration from 0.5 (equal to sea water) to 1.0 M resulted in a higher intracellula...

The classical Voorn-Overbeek thermodynamic theory of complexation and phase separation of oppositely charged polyelectrolytes is generalized to account for the charge accessibility and hydrophobicity of polyions, size of salt ions, and pH variations. Theoretical predictions of the effects of pH and salt concentration are compared with published experimental data and experiments we performed, on...

A simple method for the rigorous derivation of lithogenic index or percent cholesterol saturation, embodying both relative and total lipid concentrations, is described. We recently demonstrated that under physiological conditions only two key physical-chemical variables, the bile salt-lecithin ratio and the total lipid (bile salts + lecithin + cholesterol) concentration determine the equilibriu...

1. The distribution of angiotensinogen and endogenous renin-like activity were analysed in different areas of the central nervous system in normal and DOC-salt-treated hypertensive rats. 2. Angiotensinogen concentration and reninlike activity were significantly increased in the cerebral cortex, cerebellum, hypothalamus and brain stem of the DOC-salt-treated rats 30 days after the initiation of ...

The authors have used the concentration of salt in sweat as an objective test to demonstrate the existence of a group of hypertensive patients with clinical signs of hyperadrenocortical function. The significantly lower concentration of salt in the sweat of patients with this endocrine hypertensive syndrome distinguishes them from other hypertensive patients who show no significant difference f...
