Multi-ion detection and molecular switching behaviour of reversible dual fluorescent sensor.

The selective chemosensing behaviour of imidazole bisthiocarbohydrazone (IBTC) towards F and Cu are studied via colorimetric, UV-Visible, fluorescence spectra studies, and binding constants were calculated. The H NMR titration study strongly support that the deprotonation of IBTC followed by the hydrogen bond formation via N1H1 and N2H2 protons with fluoride ion. The fluorescence inactive IBTC-Cu complex became fluorescence active in the presence of perchlorate (ClO) ion.

Gross morphological study of the renal pelvicalyceal patterns in human cadaveric kidneys.

Introduction: The knowledge of detailed calyceal anatomy is essential for performing urologic procedures such as percutaneous nephrolithotomy, percutaneous nephrostomy, flexible ureterorenoscopy, endopyelotomy, and retrograde renal surgery. This study was performed to analyze the various patterns of pelvicalyceal system in the South Indian population, and compare these with previously published studies in different populations.

Methods: The study was conducted in 100 kidney specimens.

Gallic acid induces GLUT4 translocation and glucose uptake activity in 3T3-L1 cells.

GLUT4, a 12 transmembrane protein, plays a major role in insulin mediated glucose transport in muscle and adipocytes. For glucose transport, the GLUT4 protein needs to be translocated to the plasma membrane from the intracellular pool and it is possible that certain compounds may be able to enhance this process. In the present work, we have shown that gallic acid can increase GLUT4 translocation and glucose uptake activity in an Akt-independent but wortmannin-sensitive manner.

Antistressor activity of Ocimum sanctum (Tulsi) against experimentally induced oxidative stress in rabbits.

Fresh leaves of Ocimum sanctum (O. sanctum) were evaluated for antistress activity against experimentally induced oxidative stress in albino rabbits. Animals of the test group received supplementation of 2 g fresh leaves of O.
