Hydrogen sulphide (H2S) is an endogenous gaseous signalling molecule observing cardioprotective qualities in various experimental models. However, its therapeutic application limited due to rapid release vivo and potential toxicity. Controlled-release nanoparticles (NPs), such as polylactic-co-glycolic acid (PLGA) NPs entrapping H2S compounds may address these issues. PLGA NPs’ encapsulating so...

L-Asparaginase has remarkable properties which make it useful in dual pharmaceutical and food industries.In this study, simple and advantageous method has been validated for rapid and precise determination of intracellular L-Asparaginasein bacterial species. A suspension of bacterial cells was used instead ofcell extract and incubated by substrate (asparagine) after simple wash and centrifugati...

Various washing protocols have been assessed for efficacy using Agilent LC/MS and GC/MS instrumentation to measure pesticide residues in tomatoes and other produce. Washing procedures in water and various solutions, with and without sonication, were evaluated in the laboratory. In general, the effect of sonication depended on the washing treatment and on the pesticide. A separate experiment mea...

Sonicated unilamellar lipid vesicles, consisting of egg lecithin, stearylamine, and cholesterol in 7:2:1 molar ratios, promoted the aggregation of tobacco (Nicotiana glutinosa) protoplasts with the aid of mono- or divalent cations.A reaction mixture containing liposomes (0.4 micromoles lipid per milliliter), 50 millimolar CaCl(2), 0.5 molar mannitol, and 5 x 10(5) protoplasts per milliliter res...

Co-cultivation and effective downstream processing of microalgae oleaginous yeast are potential strategies to enhance lipid yield. The findings this work suggest that each cultivable partner should be screened optimized for the best mutualistic co-cultures. In case, T. pullulans was found most culture with S. obliquus, C. sorokiniana, protothecoides along additional cell disruption techniques. ...

BACKGROUND Microalgae can synthesize starch with productivity higher than conventional terrestrial crops, without the need for arable land. However, little is known about processes to extract from microalgae. Here, a biorefinery process described including microalgal cell disruption followed by extraction of and pigments aqueous two-phase system (ATPS) using choline chloride polypropylene glyco...

existence of 2-methylpropane-2-thiol as an organosulfur and odorant compound in the soil could causes environmental problem and social dissatisfaction. in this study, remediation of this type of thiol using ultrasound is investigated. central composite design (ccd) based on response surface model (rsm) was used to obtain effects of the main factor (power, sonication time and amount of water) an...

We propose a simple model to describe the cavitation-induced breakage of mesoscale filaments during their sonication in solution. The model predicts a limiting length below which scission no longer occurs. This characteristic length is a function of the tensile strength and diameter of the filament, as well as the solvent viscosity and cavitation parameters. We show that the model predicts accu...
