Spin trapping techniques combined with electron spin resonance spectroscopy were used to capture and detect free radicals generated in vivo during exposure to ionizing radiation. Tissue extracts of mice given an intraperitoneal or intragastric dose of the spin trap, alpha-phenyl-t-butyl nitrone prior to exposure to gamma radiation (2 to 5 Gy), contained a(More)
In a SAR study, we have synthesized a few 1H-pyrazole carboxylate related microbicides using Vilsmeier reagent. The anti-microbial screening results of 1H-pyrazole-3-carboxylate are reported here for the first time. The effect of 1H-pyrazole carboxylates on the mycelial growth of plant pathogenic fungi is revealed. The first X-ray structure in the family of(More)
The present study was carried out to determine the water quality in terms of physicochemical characteristics and plankton distribution in the coastal waters of Kattumavadi, Palk Bay for a period of one year from April 2002 to March 2003. Air and surface water temperatures varied from 28 degrees C to 32.50 degrees C and from 27.5 to 32.0 degrees C while(More)
Nanotechnology based Pharma has emerged significantly and has influenced the Pharma industry up to a considerable extent. Nanoparticles technology holds a good share of the nanotech Pharma and is significant in comparison with the other domains. Electrospraying technology answers the potential needs of nanoparticle production such as scalability,(More)
Nanotechnology refers to the fabrication, characterization, and application of substances in nanometer scale dimensions for various ends. The influence of nanotechnology on the healthcare industry is substantial, particularly in the areas of disease diagnosis and treatment. Recent investigations in nanotechnology for drug delivery and tissue engineering(More)
Pharmaceutically active compounds require different modes of drug delivery systems to accomplish therapeutic activity without loss of its activity and lead to exhibit no adverse effects. Originating from ancient days, pulmonary mode of drug delivery is gaining much importance compared to other modes of drug delivery systems with respect to specific(More)
Myocardial tissue lacks the ability to appreciably regenerate itself following myocardial infarction (MI) which ultimately results in heart failure. Current therapies can only retard the progression of disease and hence tissue engineering strategies are required to facilitate the engineering of a suitable biomaterial to repair MI. The aim of this study was(More)
BACKGROUND Heart failure due to myocardial infarction remains the leading cause of death worldwide owing to the inability of myocardial tissue regeneration. The aim of this study is to develop a core/shell fibrous cardiac patch having desirable mechanical properties and biocompatibility to engineer the infarcted myocardium. METHOD We fabricated(More)
Controlled release dosage forms of proteins and other biomolecules can be prepared by microencapsulating them in polymeric microspheres. Proteins are subjected to potentially damaging effects of sonication and exposure to organic solvents during the microencapsulation process. The relatively stable enzyme lysozyme was dissolved in aqueous buffer and(More)
Drug-eluting medical implants are more common, particularly for fighting against cancers. FDA and other drug regulatory bodies have approved many nanoformulated devices eluting active pharmaceutical ingredients and thus there is growing demand for further value- added devices. Nanofibre membranes are known for its versatility of drug incorporation and(More)
