Synthesis of Fluorophore Decorated Single-Walled Carbon Nanotubes for Cytocompatibility.

We report rhodamine based fluorophore derivative for the stable dispersion of single-walled carbon nanotubes (SWCNTs), which can afford better fluorescent label to carbon nanotubes (CNTs). The nanotubes-fluorophore conjugates are helpful in achieving stable dispersion in polar and non-polar solvents with intense fluorescence. The product was characterized through NMR, Mass spectrometry, Raman, XPS, SEM, AFM and Fluorescence measurements.

Cr-induced cellular injury and necrosis in Glycine max L.: Biochemical mechanism of oxidative damage in chloroplast.

Chromium-induced toxicity and mechanisms of cell death involved in plants are yet to be fully elucidated. To understand the events of these processes, the stress response of the soybean plant using trivalent and hexavalent chromium compounds, namely, basic chromium sulphate (BCS) and potassium dichromate (KCrO) was investigated. The leaf surface morphology for stomatal aperture, wax deposition and presence of trichomes for chromium accumulation was examined by SEM-EDAX and light microscopy.

secretion of zymogens by bovine pancreatic acini and ultra-structural analysis of exocytosis.

The aim of this study is to establish a bovine pancreatic acinar cell culture model with longer viability and functionality. The cells could be maintained in a functional state for upto 20 days with normal morphology. Cells were positive for amylase as observed by immunofluorescence staining.

In vitro anti inflammatory activity of Aloe vera by down regulation of MMP-9 in peripheral blood mononuclear cells.

Aim Of The Study: The anti-inflammatory activity of Aloe vera was investigated through MMP inhibition studies. The effect of Aloe vera on MMP-9 inhibition was tested on peripheral blood mononuclear cells (PBMC).

Materials And Methods: Peripheral blood mononuclear cells (PBMC) were isolated from the heparinised venous blood by Ficoll Diatrizoate gradient centrifugation.
