Alzheimer's disease (AD) pathogenesis involves an imbalance between free radical formation and destruction. In order to obtain a novel preclinical anti-AD drug candidate, we synthesized a series of novel hydroxyl chalcone analogs which possessed anti-free radical activity, and screened their effects on scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) and OH free radicals in vitro. Compound C7, ...

The modern living lifestyle is known to produce various physical and psychological stresses and subject the individual to produce oxidative stresses as well. The aim of this study has been to assess the effect of yogic breathing exercises (pranayama) on the oxidatives stress. The study group consisted of 30 young male volunteers, trained for the purpose of this study and an equal number of cont...

Administration of cadmium (Cd) significantly increased the peroxidation markers such as malondialdehyde and protein carbonyls along with significant decrease in antioxidant markers such as super oxide dismutase and reduced glutathione in liver and kidney tissues. Cadmium also caused a significant alteration in hepatic and renal functional markers in serum viz. total protein, albumin, alanine tr...

Triphala, an Indian ayurvedic triherbal formulation, is an equiproportional mixture of fruits of three herbs, amalaki (Emblica officinalis), haritaki (Terminalia chebula) and bibhitaki (Terminalia bellerica). The present study focused on phytocompounds detection and comparative analysis of various biochemical activities in the aqueous and methanolic extracts of triphala and its constituting her...

Prostate cancer is the most prevalent cancer found in men above the age of fifty years and is frequently diagnosed in men between 45 and 89 years of age with a median age of 72 years. This work was undertaken to assess oxidative stress and anti oxidant status in patients with carcinoma of prostate. Glutathione (GSH), Malondialdehyde (MDA), Super Oxide Dismutase (SOD) levels in Erythrocytes and ...

Carbon tetra chloride (CCl4) induced acute hepatotoxicity causes severe damage to hepatocytes and affects the liver functions which resemble various liver ailments like hepatitis, jaundice, cancer etc. Using 12-different fruits, formulation F1 and F2 were prepared. Hepatoprotective potential of the formulations was assessed using HepG2 cell (in vitro) and rat model (in vivo). Biochemical parame...

Milk thistle extract is a well-known hepatoprotectant with low bioavailability (20-50%). The objective of the present study is to prepare and characterize silymarin phytosomes and to test the hepatoprotective effect of the phytosomes in CCl4 induced liver injury in rats compared to milk thistle extract. Phytosomes were prepared using lecithin from soybeans and from egg yolk. The prepared phytos...

Mediator release from rat peritoneal and human lung mast cells as well as human leukemic basophils was examined to determine whether super-oxide (O(-) (2)) was concomitantly generated. Immunologic or nonimmunologic stimulation of each preparation induced parallel release of histamine and O(-) (2) within 2 min. O(-) (2) production was quantitated by superoxide dismutase (SOD)-inhibitable chemilu...

The objective of this study was to characterize the non-enzymatice and enzymatic antioxidants of E. littorale Blume grown under wild condition. Aerial and sub-aerial parts of the plants exposed to different heat stress was analyzed for the non enzymatic antioxidants such as Tocopherol, Phenols, DPPH, FRAP and enzymatic antioxidants such as Polyphenol oxidase, Peroxidase, Catalase, Super Oxide D...
