INTRODUCTION Antibiotic associated diarrhea (AAD) is a frequently encountered adverse event following antibiotic administration. Evidence suggests that probiotics may be beneficial in preventing and decreasing the severity of AAD. MATERIAL AND METHODS Adult patients who were prescribed antibiotics for 3-14 days were enrolled from eight Canadian centers. Study treatment was randomized at a 1 :...

Dedifferentiation and proliferation of endogenous cardiomyocytes in situ can effectively improve cardiac repair following myocardial infarction (MI). 6-Bromoindirubin-3-oxime (BIO) and insulin-like growth factor 1 (IGF-1) are two potent factors that promote cardiomyocyte survival and proliferation. However, their delivery for sustained release in MI-affected areas has proved to be challenging. ...

in this study, a bacterial species which could remove lead from wastewater was isolated from lead contaminated soil prepared in the laboratory. based on the biochemical and morphological characterization the bacteria were identified as brevundimonas vesicularis. the biosorption potentiel of powdered dry biomass of b. vesicularis was investigated by batch adsorption experiments. it was found tha...

BACKGROUND To evaluate the impact and safety of different surgical techniques for aortic root replacement (ARR) on early and late morbidity and mortality in septuagenarians undergoing ARR. METHODS Ninety-five patients (73.8 +/- 3.2 years) were operated and divided into three groups according to the aortic root procedure; MECH-group (n = 51) patients with a mechanical composite graft, BIO-grou...

In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...

Background/Aims: Will immunization with an experimental Pre-S1/Pre-S2/S hepatitis B vaccine (Bio-Hep-Be) induce faster seroprotection using fewer doses as compared with a yeast derived S vaccine (Engerix B). Methods: Healthy volunteers, nˆ 36, mean age 23 y, randomized to receive 2 or 3 doses of both vaccines given months 0 and 6, or 0, 1 and 6. Results: Following primary immunization, seroprot...

Olive milling wastewater is a major problem facing the Mediterranean countries producing olive oil like Egypt. In the present study, olive milling wastewater rich with organic phenolic compounds, macro and micro nutrients was used as growing media for cyanobacteria. The cyanobacteria were grown on wastewater to obtain two biofertilizers, one bioformulated from single culture of Spirulina pl...

Lanthanide oxide nanoparticles attract great interest as potential fluorescent labels for biological applications. They offer long fluorescence lifetimes (about 1 ms) and a lack of photo bleaching. These properties allow the label fluorescence to be separated from the short-lived bio fluorescence and make possible the development of new detection techniques in biochemistry. The morphology of th...
