background: medicinal plants (especially belong to lamiaceae family) are potential sources of new drugs to improve the treatment of diseases whose treatment is associated to anti-oxidative agents. in this paper, the ferric reducing ability of plasma (frap) activity of some lamiaceae and apiaceae species, has been evaluated. methods: aerial parts of the plants were dried, cut into small pieces a...

The lipid coating introduced directly on (polystyrene sulfonate/polyallylamine hydrochloride)5 polyelectrolyte microcapsule surfaces significantly reduces the permeability of capsule walls estimated by fluorescence recovery after photobleaching (FRAP).

BACKGROUND Chinese medicine has its own uniqueness, advantageous in the treatment of hepatic diseases, and they were widely used in the oxidation. At the same time, oxidation is one of the mechanism of protect liver. MATERIALS AND METHODS In the present study, the antioxidant activity in vitro of different extracts from Compound Lobelia were estimated respectively by the methods of measuring ...

Discussion continues as to whether de novo hypertension in pregnancy with significant proteinuria (pre-eclampsia; PE) and non-proteinuric new hypertension (gestational hypertension; GH) are parts of the same disease spectrum or represent different conditions. Non-pregnant hypertension, pregnancy and PE are all associated with oxidative stress. We have established a 6 weeks postpartum clinic for...

Recent advances in nanoengineering and super-resolution microscopy have enabled new capabilities for creating and observing membrane curvature. However, the effects of curvature on single-lipid diffusion have yet to be revealed. The simulations presented here describe the capabilities of varying experimental methods for revealing the effects of nanoscale curvature on single-molecule mobility. T...

Lateral diffusion of membrane constituents plays an important role in membrane organization and represents a central theme in current models describing the structure and function of biological membranes. Fluorescence recovery after photobleaching (FRAP) is a widely used approach that provides information regarding dynamic properties and spatial distribution of membrane constituents. On the basi...
