Cinnamon Attenuated Long-Term IGT-Induced Retinal Abnormalities via Regulation of Glucose Homeostasis in Neonatal Streptozotocin Induced Rat Model.

Diabetic retinopathy (DR) is one of the major causes of blindness all over the world. According to the previous studies, impaired glucose tolerance (IGT) has been linked to retinal dysfunction/vascular damage. Decreased retinal function is an initial event of early DR.

Purification and structural elucidation of three bioactive compounds isolated from Streptomyces coelicoflavus BC 01 and their biological activity.

The strain Streptomyces coelicoflavus BC 01 was isolated from mangrove soil and used as inoculum for submerged fermentation. The fermented broth was extracted with ethyl acetate, the crude extract was subjected to silica gel column chromatography and the homogeneity of the isolated fractions was determined by TLC and then subjected to RP-HPLC for their purity. The purification steps led to the isolation of three pure bioactive compounds named as BC 01_C1, BC 01_C2 and BC 01_C3.

Association of mitochondrial displacement loop polymorphisms with risk of colorectal cancer in south Indian population.

Mitochondrial displacement loop (D-loop) is the hot spot for mitochondrial DNA (mtDNA) alterations which influence the generation of cellular reactive oxygen species. In the present study, we sequenced the entire mitochondrial D-loop region (1124 bp) of colorectal cancer (CRC) patients (n = 174) and controls (n = 170) of south Indian origin to identify significant mutations/polymorphisms. Our results showed 152 polymorphisms in the D-loop region of patients and/or controls.

Manganese-superoxide dismutase (Mn-SOD) overexpression is a common event in colorectal cancers with mitochondrial microsatellite instability.

Mitochondrial displacement loop (D-loop) is a hot spot for mitochondrial DNA (mtDNA) alterations that effects cellular reactive oxygen species (ROS) generation. Manganese-superoxide dismutase (Mn-SOD) is a major antioxidant enzyme that protects cells from ROS-mediated damage. In the present study, we investigated the relationship between sequence alterations of mitochondrial D-loop and Mn-SOD expression in colorectal cancer (CRC).

Molecular characterization and its antioxidant activity of a newly isolated Streptomyces coelicoflavus BC 01 from mangrove soil.

Objective: To isolate and identify the biologically active strain of Streptomyces species from mangrove soil of Visakhapatnam region.

Materials And Methods: Actinomycetes are isolated by using starch casein agar media and four potential strains were selected to evaluate the antioxidant activity by using the standard methods DPPH, FRAP and total antioxidant capacity. Further, significant antioxidant activity strain characterized by morphological, physiological, biochemical and molecular characterization.

Study of sugarcane pieces as yeast supports for ethanol production from sugarcane juice and molasses using newly isolated yeast from toddy sap.

A repeated batch fermentation system was used to produce ethanol using Saccharomyces cerevisiae strain (NCIM 3640) immobilized on sugarcane (Saccharum officinarum L.) pieces. For comparison free cells were also used to produce ethanol by repeated batch fermentation.
