Recent studies concerning the isolation and purification of exopolysaccharides from suspension-cultured tomato (Lycopersicon esculentum L. var. San Marzano) cells and the description of a simple, rapid and low environmental impact method with for obtaining polysaccharides from solid tomato-processing industry wastes are reported. Their chemical composition, rheological properties and partial pr...
One of the promising aspects of the immunological research on chemical war gas is to investigate the immunogenicity of some hazardous compounds such as mustard gas. Mustard gas is categorized as a "hapten" based on its physical and chemical properties. Haptenic chemicals which do not possess immunogenicity could be immunogenic experimentally when conjugated with a suitable protein carrier...
Abstract The physical/chemical abatement of gas pollutants creates many technical problems, is costly and entails significant environmental impacts. Biological purification off-gases a cheap ecologically safe way neutralization pollutants. Despite the recent advances, main technological challenge nowadays volatile organic compounds (VOCs) hydrophobic character due to their low solubility in wat...
Background and Objectives: Each patient has renal failure in any dialysis with high water volume, which is in direct contact with the patient's blood. The presence of any chemical and microbial contamination in water used in homodynamic devices can be very dangerous for these patients. The purpose of this study was to determine the efficiency of reverse osmosis open systems in improving the wat...
Drug discovery proceeds as a multi-stage process, from the identification of a potential therapeutic target through lead generation, lead optimization, preclinical evaluation to clinical testing, before a new medicine is marketed. Uniting synthetically accessible chemical space with disease relevant biological space represents a significant challenge. Industrial chemical biology approaches have...
Lipases (E.C. 3.1.1.3) can be broadly defined as enzymes that catalyze the hydrolysis of ester bonds in substrates such as vitamin esters, phospholipids, triglycerides (TGs) and cholesteryl esters [1]. Interest in lipases has been increasing in the past few years because of the actual and potential uses of this enzyme in applications like hydrolysis of fats and oils, organic synthesis, modifica...
