Fourteen saxicolous lichens from trans-Himalayan Ladakh region were identified by morpho-anatomical and chemical characteristics. The n-hexane, methanol and water extracts of the lichens were evaluated for their antioxidant capacities. The lichen extracts showing high antioxidant capacities and rich phenolic content were further investigated to determine their cytotoxic activity on human HepG2 ...

BACKGROUND Iron in the overloaded condition in liver promotes the overproduction of free radicals that lead to oxidative stress and ultimately hepatic damage. The present study was designed to evaluate the ameliorating potential from iron overloaded hepatotoxicity by the glycosidic fraction from Spondious pinnata bark (SPW1) along with its antioxidant property. METHODS The fraction was tested...

The present study investigates a concentration-dependent assessment of scavenging property and antioxidant activity in the extracts of Emblica officinalis Gaertn. syn. Phyllanthus emblica L. fruit using various in vitro assays. A correlation of aqueous and ethanolic extract of Emblica fruit along with different known standards for its antioxidative properties was made by performing assays like ...

OBJECTIVE The present study was an attempt to study total phenolic content and antioxidant property of the crude ethanolic extract of the roots of Azadirachta indica (A. indica). MATERIALS AND METHODS To evaluate the antioxidant properties of the crude extract, some complementary test systems, namely DPPH free radical scavenging assay, reducing power assay, and ferrous ion chelating ability a...

The influence of particle size and extraction solvent on the antioxidant properties of aqueous and ethanolic extracts of tea (Camellia sinensis), ginger (Zingiber officinale), and tea-ginger (2:1) blend was investigated. The powder sizes studied were 0.425, 0.710, and 1.180 mm. Extracts were analyzed for DPPH radical scavenging activity, ABTS radical scavenging activity, total phenol content (T...

The results in this paper were motivated by the case when the inverse semigroup is the McAlister monoid MX on a set X. In [1] we considered some very large convolution algebras on MX , including some C ∗-algebras. Our main focus in [1] was deciding on the primitivity of the algebras, and one key tool was the use of generalized Rukolaine idempotents. To define these very large convolution algebr...

Polyvinyl benzyl chloride (PVBC) was synthesized by free radical polymerization of 4-vinylbenzyl using benzoyl peroxide initiator at 60 °C. PVBC synthesised in different solvents such as toluene, xylene, 1,4-dioxane, and tetrahydrofuran. The polymers were structurally characterized 1H NMR FTIR spectroscopic techniques. thermal property the polymer investigated thermogravimetric analysis (TGA) d...

factors such as oxidative stress and reduced acetylcholine level have been implicated in alzheimer’s disease (ad) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. centaurea is a genus with about 500 species world wild, many of them have shown to possess biologic act...

the purpose of this study was to describe the feasibility of a combined preoperative chemoradiation program ib-iia, bulky and suspicious iib by radical surgery in patients with stage ib-iib cervical cancer. from september 1999 to april 2002, 30 patients with carcinoma of the cervix were treated with preoperative external beam radiotherapy of 45 gy in 5 weeks. patients received concurrent contin...

breast sarcomas have relatively been rare and accounted for 1% of all primary malignant tumors of the breast. pure and primary chondrosarcoma of the male breast would be an extremely rare tumor. it might arise either from the breast stroma itself, or from underlying bone or cartilage. a 65-year-old man has presented with a rapidly growing breast mass since 5 months. physical examination has est...
