The role of augmented aldosterone production in pregnancy is poorly understood. Whereas some consider aldosterone secretion in pregnancy excessive, others suggest that this is a compensatory phenomenon. According to yet another view, mechanisms other than the renin-angiotensin-aldosterone system control sodium homeostasis in pregnancy. Metabolic balance studies were performed on 14 3rd trimeste...

The interaction force between a rigid silica sphere and a butyl or octyl acetate droplet was measured in an aqueous environment using atomic force microscopy (AFM). The force measurements were performed without added stabilizers and the observed force behavior was found to be dependent on the type of inorganic electrolyte present, where the interfacial tension was constant over the electrolyte ...

Introduction: Curcuma zedoaria Roscoe (C. zedoaria) is used in traditional medicine for various diseases, including inflammation. This study aimed to evaluate the vitro anti-inflammatory activity of aqueous extract C. rhizome and its fractions develop an cream incorporating extract. Methods: The crude was prepared by decoction method. A portion it freeze-dried other part subjected sequential fr...

In this study, the effect of sodium tungstate on anaerobic digestion waste sewage sludge (WSS) was investigated. Methane production enhanced by in a dose-dependent manner. Sodium did not affect hydrolysis stage as same level protease activity detected WSS sample with or without tungstate. At acidogenesis stage, concentration acetate decreased during supplemented whereas that isobutyrate increas...

In its natural environment, Escherichia coli is exposed to short-chain fatty acids, such as acetic acid or propionic acid, which can be utilized as carbon sources but which inhibit growth at higher concentrations. DNA microarray experiments revealed expression changes during exponential growth on complex medium due to the presence of sodium acetate or sodium propionate at a neutral external pH....

The synthesis of compound (2) was achieved using cyclization method of compound (1) with ethyl chloro acetate and fused sodium acetate. Compound (2) was underwent mannich reaction to give compound (3a-3f). The Chemical structures were elucidated by IR, 1 HNMR, and elemental analysis. The compounds (2) and (3a-3f) have been screened for in vitro antimicrobial action against various strains of ba...

The reaction of 1,5-dibenzyl-3-propargyl-1,5-benzodiazepine-2,4-dione with ethyl azido-acetate in the presence of copper sulfate pentahydrate and sodium ascorbate leads to the formation of the title regioisomer, C(30)H(29)N(5)O(4), which features a phenyl-ene ring fused with a seven-membered diazepinyl ring. The latter ring adopts a boat conformation (with the methyl-triazolylacetate-bearing C ...

the mechanism by which lead may cause a perturbotion in the nevous system is through the nitric oxide synthase. in this study the effect of lead acetate on the hippocampal constitutive nitric oxide production was studied. the variation in the nitric oxide production may contribute to physiological lead neurotoxicity in vivo. different concentrations of lead acetate (10-9 to 10-6 m), wre added t...

The effect of the sugars sucrose, glucose, and trehalose on the structural and colloidal stability of lysozyme has been investigated using differential scanning calorimetry and quasi-elastic light scattering, respectively. While sugars are known to increase the temperature at which thermal denaturation of protein occurs, it is not clear if, under the same solution conditions, greater colloidal ...
