Angelica essential oil (AO), a major pharmacologically active component of Angelica sinensis (Oliv.) Diels, possesses hemogenesis, analgesic activities, and sedative effect. The application of AO in pharmaceutical systems had been limited because of its low oxidative stability. The AO-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using respons...

The present study was performed to compare the antioxidative and whitening activities of fermented soybean extract (FSB) and non-fermented soybean extract (SB). Antioxidative and whitening activities of FSB and SB were evaluated by the determination of DPPH, superoxide radical and hydroxyl radical scavenging activities, linoleic acid inhibition activity, and tyrosinase inhibition activity. FSB ...

an efficient method for purification of yard-glass shaped boron nitride nanotubes (yg-bnnts) fabricated via a chemical vapour reaction (cvr) route has been developed. impurities including carbon, boron nitride (bn), and fe species in the pristine yg-bnnt sample are removed by a combined physical and chemical procedure which involves ultrasonication, high temperature oxidation, hot-water washing...

the purpose of this investigation was to determine the antioxidant potentials and anti-glucosidase activities of six tropical medicinal plants. the levels of phenolic constituents in these medicinal plants were also quantified and compared. antioxidation potentials were determined colorimetrically for scavenging activities against dpph and no radicals. metal chelating assay was based on the mea...

The hippocampus is a key structure for encoding and processing memory and for spatial orientation, which are among the cognitive functions most sensitive to cerebral ischemia, hypoxia, and vascular dementia (VD). Since hippocampal formation is one of the principle forebrain targets for arginine-vasopressin (AVP) innervations arising in the hypothalamic paraventricular nucleus (PVN), we explored...

Edemallschemia-reperfusion iajllrylLow-dose irradiation/Reactive oxygen species/Antioxidation function. We have reported that low-dose, unlike high-dose, irradiation enhanced antioxidation function and reduced oxidative damage. On the other hand, ischemia-reperfusion ajury is induced by reactive oxygen species, In this study, we examined the inhibitory effects of prior Iow-dose X-irradiatien on...

Understanding how pathogenic fungi adapt to host plant cells is of major concern to securing global food production. The hemibiotrophic rice blast fungus Magnaporthe oryzae, cause of the most serious disease of cultivated rice, colonizes leaf cells asymptomatically as a biotroph for 4-5 days in susceptible rice cultivars before entering its destructive necrotrophic phase. During the biotrophic ...
