2-Oxindole and related heterocycles: synthetic methodologies for their natural products and related derivatives.

Natural goods, medications, and pharmaceutically active substances all contain substituted oxindoles. Generally, the C-3 stereocenter of the substituents of oxindoles and their absolute arrangement have a substantial impact on the bioactivity of these substances. In this case, the desire for contemporary probe and drug-discovery programs for the synthesis of chiral compounds using desirable scaffolds with high structural diversity further drives research in this field.

Sustainable Synthesis of Nanoscale Zerovalent Iron Particles for Environmental Remediation.

Nanoscale zerovalent iron (nZVI) particles represent an important material for diverse environmental applications because of their exceptional electron-donating properties, which can be exploited for applications such as reduction, catalysis, adsorption, and degradation of a broad range of pollutants. The synthesis and assembly of nZVI by using biological and natural sustainable resources is an attractive option for alleviating environmental contamination worldwide. In this Review, various green synthesis pathways for generating nZVI particles are summarized and compared with conventional chemical and physical methods.

Improvement of glutathione and total antioxidant status with yoga.

Objective: Several studies suggest that yoga can decrease oxidative stress. However reports are scanty regarding whether yoga training can improve the glutathione level of individual. This study is designed to appraise the role of yoga in maintaining glutathione (reduced and oxidized) levels and antioxidant status.

MICROSURGICAL COMPOSITE TISSUE TRANSPLANTATION: A CLINICAL TRIAL.

Twenty four patients suffering from various ailments necessitating flap cover were treated with composite tissue transplantation by microsurgical techniques from July 1992 to July 1996. There were 21 males and 3 females in the 10 to 50 years age group. Four patients were provided flap cover on the face for congenital lesions and twenty patients required flap cover for sub acute/chronic trauma.
