ion of a hydrogen atom from poly unsaturated fatty acids (PUFA); the hydroxyl radical is capable of starting this reaction sequence [4, 5]. While Piper species are reported to have wide spectrum of biological activity but its antioxidant potential has not been established so far, making it important and interesting to analyze the antioxidant potential of Piper betle leaf extract in the present ...
Mexican sunflower is native to Mexico and Central America and was introduced into China early last century. Now it has widely naturalized and is exhibiting increasing invasiveness in South China. As this species often dominates bare ground, a habitat characterized by extreme fluctuation in temperature and water, it is reasonable to hypothesize that it has special adaptations to high temperature...
Petioles of the plant piper betle-bengal variety have been subjected for extraction employing standard procedure and the crude extract obtained has been evaluated for its diastase like activity and other physico-chemical properties to investigate further its possible biological and pharmacological activities.
The induction of apoptosis by Piper betel leaf extracts during 7, 12 dimethylbenz [a] anthracene (DMBA) induced hamster buccal pouch (HBP) carcinoma was studied in male Syrian hamsters using DNA fragmentation and the apoptosis-associated proteins, tissue transglutaminase (tTG) and Bcl-2. Hamsters were divided into four groups of six animals each. Animals in group 1 were painted with a 0.5% solu...
PREMISE OF THE STUDY Documented fossil floras in the neotropics are sparse, yet their records provide evidence on the spatial and temporal occurrence of taxa, allowing for testing of biogeographical and diversification scenarios on individual lineages. A new fossil Piper from the Late Cretaceous of Colombia is described here, and its importance for assessing diversification patterns in the genu...
OBJECTIVE Nitric oxide produced by endothelial nitric oxide synthase (eNOS) possesses multiple anti-atherosclerotic properties. Hence, enhanced expression of eNOS and increased Nitric oxide levels may protect against the development of atherosclerosis. Piper sarmentosum is a tropical plant with antioxidant and anti-inflammatory activities. This study aimed to investigate the effects of Piper sa...
hydrogeochemistry and concentration of heavy metals in the kaka-reza river water (lorestan province)
the main purpose of this research is to evaluate the hydrochemical properties, con-trolling processes and metal concentrations in kaka-reza river water (lorestan province). to this end, 15 water samples were collected and physicochemical prop-erties (ph-ec), cation-anion contents along with concentrations of some heavy metals were determined using the standard analytical methods. the results re...
Abstract The Pindul Cave Underground River is a source of water that used for irrigation, fulfilling domestic needs, and also tourism. in the comes from surface river flow enters ponor (Allogenic Recharge) so it affects quality River. research was conducted with aim temporally analyzing samples were taken periodically one year. Water analyzed by comparing laboratory field tests standards hydrog...
Background: Long-term glucocorticoid therapy causes secondary osteoporosis leading to pathological fractures. Glucocorticoid action in bone is dependant upon the activity of 11β-hydroxysteroid dehydrogenase type 1 enzyme (11β-HSD1). Piper sarmentosum is a local herb that possesses the ability to inhibit 11-βHSD1 enzyme activity. We aimed to determine the effects of Piper sarmentosum wat...
Studying groundwater quality is crucial for ensuring its safety because it widely used drinking and domestic, agricultural, industrial purposes. Owing to the lack of surface water in Tabuk area Saudi Arabia, here wells are one primary sources drinking, agriculture, industry. Groundwater determined by aquifer characteristics regional geology, extensively influenced both natural anthropogenic act...
