Long-chain saturated fatty acids (C(13) to C(18)) and fatty alcohols (C(12) to C(18)) were well utilized by three different soil isolates of Cladosporium resinae as the sole carbon and energy sources in static liquid cultures. Shorter-chain compounds, down to C(5), did not support growth and were in fact toxic towards the fungus growing on glucose. Rapid and considerable potassium efflux, prote...

The Zinc-air primary batteries (ZAB’s) are prone to electrolyte leakage upon exposure high temperature and humidity conditions. Potassium hydroxide is a hygroscopic corrosive compound it can cause various electrochemical corrosion failures for the attached electronics inside device. In this study, effect of humid conditions on from three different Zinc Air Battery variants were investigated. ex...

Fourteen polyene antibiotics and six of their semisynthetic derivatives were compared for their effects on potassium (K(+)) leakage and lethality or hemolysis of either Saccharomyces cerevisiae or mouse erythrocytes. These polyene antibiotics fell into two groups. Group I antibiotics caused K(+) leakage and cell death or hemolysis at the same concentrations of added polyene. In this group fungi...

The mechanism of arsine (AsH3) toxicity is not completely understood. In this investigation, we determined AsH3 and arsenite (AsIII) toxicity in Sprague Dawley rat blood, liver, and kidney. In all systems, there were dose- and time-dependent responses. Red blood cells were very susceptible to AsH3 toxicity. This was demonstrated by an immediate intracellular potassium loss and by hemolysis and ...

The role of zinc (Zn) in enhancing defense capacity of several plants against salinity has been demonstrated but there is limited information on the impact of Zn nutrition on alleviating salinity-induced oxidative damage in olive. One-year-old seedlings of two varieties of olive (Olea europaea L. cvs. Frontoio and Conservolea) supplied with three Zn levels (0, 1 and 5 mM in the form of ZnSO4.7H...

Thermostable direct hemolysin purified from cultured filtrates of a pathogenic strain of Vibrio parahaemolyticus (1) has been reported to have potent cardiotoxic and hemolytic activities (2, 3). Intravenous injection of small doses (10 to 20 ug/kg) of hemolysin killed the rats within several hr. Electrocardiograms of rats after administration (i.v.) of hemolysin showed significant changes due t...

The objective of the present research was to develop cinnamon oil nanoemulsions using soy protein isolate and lecithin as food grade natural emulsifiers. For this purpose, stable cinnamon oil nanoemulsion (droplet diameter of 141.2 nm) prepared by ultrasonic emulsification. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of free and nanoemulsified cin...

the role of zinc (zn) in enhancing defense capacity of several plants against salinity has been demonstrated but there is limited information on the impact of zn nutrition on alleviating salinity-induced oxidative damage in olive. one-year-old seedlings of two varieties of olive (olea europaea l. cvs. frontoio and conservolea) supplied with three zn levels (0, 1 and 5 mm in the form of znso4.7h...

Biofilms constitute the predominant form of microbial life and a potent reservoir for innate antibiotic resistance in systemic infections. In the spore-forming bacterium Bacillus subtilis, the transition from a planktonic to sessile state is mediated by mutually exclusive regulatory pathways controlling the expression of genes required for flagellum or biofilm formation. Here, we identify mstX ...

The biochemical events that take place during acute hemolysis of G6PD-deficient subjects in favism are far from being elucidated. Evidence is here reported for a constantly and heavily disordered calcium homeostasis in the erythrocytes from seven favic patients. The abnormality, ie, a significantly impaired calcium ATPase activity and a parallel marked increase of intracellular calcium levels, ...
