Probiotics improve the intestinal microbiota and exert benefi ts for the host (Fuller, 1989; Parvez et al., 2006). Some strains of lactobacilli utilize lactose and alleviate lactose intolerance (Montalto et al., 2006). Lactobacillus gasseri is one of the predominant lactobacilli in the human intestine, and strains are used in probiotic foods. Lactobacillus gasseri is the major homofermentative ...

"Aluminium hydroxide dissolves in acids. From its solution in hydrochloric acid, an aluminlum salt, aluminium chloride A1C13, 6H20, is obtained. I t also combines with strong bases, dissolving for instance in a solution of sodium hydroxide and forming an aluminate, NaA102 . . . . According to the best knowledge we have on the subject, the molecule of aluminium hydroxide has the following struct...

Hydrogen peroxide is widely used for chemical treatment in various industries particularly in the textile, paper, pulp, food and dairy industries as a more environmentally-friendly alternative to chlorine that forms toxic and carcinogenic chemicals called dioxins as by-products7,9,33). However, the rapid formation of reactive oxygen species (ROS) from hydrogen peroxide, including hydroxyl radic...

Th e eff ects of various carbon and nitrogen sources on production of α-amylase by Bacillus subtilis and its mutant derivates were investigated. Th e maximum production of α-amylase by all strains was obtained in the presence of mesoinositol as the carbon source. Th ere was no more signifi cant increase in enzyme yield in the case of the supplementation of nitrogen sources, whereas malt extract...

Introduction. Polymerase chain reaction (PCR)-based diagnostic tests use purifi ed nucleic acids (NAs) from clinical samples. The NAs cation step adds time, cost, and aff ects the quality of testing. objective this study was to develop a protocol for direct saliva in genetic markers, without acids. Methods. PCR, real-time RT-PCR isothermal amplifi were used detection Results. We report markers ...

With an ever increasing fl ow of protein-based biopharmaceutical candidates entering the drug development funnel, reliable bioanalytical techniques are required to support quantitation in various biological fl uids in order to generate toxicokinetic, pharmacokinetic, and bioavailability data. Trends in the scientifi c literature clearly indicate that the coupling of liquid chromatography with t...

Rat growth hormone was extracted from an acetone powder of transplantable mammosomatotropic pituitary tumors using buffered ammonium sulphate. Active material, precipitated by increasing the ammonium sulphate concentration to 1.5 M, was fractionated first by diethylaminoethyb cellulose chroma tography and then by preparative polyacrylamide gel electro phoresis. The yield of material in the pure...

cost effectiveness of this type of dialysis, which was the main goal of our development of the technique in a cash-starved National Health Service in the United Kingdom. Dear Sir, Precedent claims are rarely correct, thus the statement by Drs Schlapper and DiazBuxo in the January 2005 issue of Blood Purifi cation [1] , that Uldall et al. [2] established the fi rst nightly home haemodialysis pro...

It is shown that scientifi c research into the intensifi cation of soybean seed separation processes necessary for developing new type purifi technologies eliminate shortcomings traditional machines, as well achieving more favorable technical and economic indicators grain cleaning equipment. ( Research purpose ) To substantiate design parameters a sorting plant highly efficient seeds. Materials...
