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)
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)
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)
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)
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)
Myocardial infarction, a main cause of heart failure, leads to loss of cardiac tissue impairment of left ventricular function. Repair of diseased myocardium with in vitro engineered cardiac muscle patch/injectable biopolymers with cells may become a viable option for myocardial infarction. We attempted to solve these problems by in vitro study by selecting(More)
Biocompatible PCL polymer nanofiber mediated sustained release of hydrophilic drug and applicability as transdermal delivery system is attempted. This new attempt to investigate water soluble vitamin delivery with hydrophobic polymer nanofiber sustained the release of the vitamin and the method is suited for the transdermal patch applications. The drug(More)
