By ultrathin serial sectioning, morphological and volumetric changes of the plastidome and chondriome have been observed in Euglena gracilis Z during bleaching in darkness with addition of sodium acetate to the culture medium. In order not to introduce any modification to the synchronization pattern during bleaching, green cells were previously grown photoautotrophically on Cramer & Myers mediu...

1. The role of the plasma sodium concentration in the regulation of aldosterone secretion and sodium excretion was investigated by comparing in 13 conscious sodium-depleted dogs the effects of the same sodium load (2.5 mmol/kg) given as either a hypertonic or hypotonic infusion. 2. The plasma sodium concentration was significantly higher and the plasma aldosterone concentration and urinary aldo...

The effect of different carbon sources was studied relative to the treatment aerobic denitrifying bacteria during nitrate-containing wastewater as well influence co-metabolism flora. Three sources, i.e., glucose, citric acid, and sodium acetate, were selected study changes in pH, nitrate nitrogen, chemical oxygen demand removal, nitrite nitrogen concentration, physical properties sludge volatil...

The mechanism whereby the vasoconstrictor response to angiotensin II (AII) is influenced by sodium balance or disease is unclear. To explore this question, the renal vascular responses (RVR) to intrarenal injections of subpressor doses of AII and norepinephrine were studied in dogs with an electromagnetic flowmeter. Acute and chronic sodium depletion increased plasma renin activity (PRA) and bl...

Indian jujube leaves (Ziziphus mauritiana Lamk) have various potential biological activity. Previous studies proven that ethanol extracted from (Z. had analgesic This study aimed to determine the total flavonoid content and activity of ethyl acetate fraction extract. Tested was prepared by maceration using as solvent followed fractionation acetate. Identification active compounds performed colo...

Cellulose acetate phthalate (CAP)membrane was interacted separately with aqueous HCl solution and aqueous HCl with sodium dodecyl hydrogen sulphate (SDS) as a surfactant and their characteristic properties were determined on the basis of water content, conductance-time and membrane potential data. The possibility of electrochemical modification of cellulose acetate phthalate membrane upon immob...
