The neonatal small intestine is susceptible to damage caused by oxidative stress. This study aimed to evaluate the protective role of antioxidant N-acetylcysteine (NAC) in intestinal epithelial cells against oxidative damage induced by H2O2. IPEC-J2 cells were cultured in DMEM-H with NAC and H2O2. After 2-day incubation, IPEC-J2 cells were collected for analysis of DNA synthesis, antioxidation ...

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 response...

The adsorption and desorption efficiencies on flavonoids and polyphenols from Eucommia ulmoides leaves by different resins were investigated, and the most suitable resin for preparation of Eucommia ulmoides leaves antioxidant was chosen. Then the crude extract of Eucommia ulmoides leaves was adsorbed by resin, and the resin was eluted by 20%, 40%, 60% and 80% (in volume) ethanol elution solutio...

BACKGROUND Photobiomodulation by red to near-infrared light-emitting diodes (LEDs) has been reported to accelerate wound healing, attenuate degeneration of an injured optic nerve, and promote tissue growth. The purpose of this study was to investigate the effect of LEDs on nerve regeneration. A histological study as well as a measurement of antioxidation levels in the nerve regeneration chamber...

NAD(+) and NADH play pivotal roles in numerous redox reactions in cells. While increasing evidence has indicated important roles of NAD(+) in cell survival and cellular functions, there has been distinct deficiency in the studies regarding the biological functions of NADH. NADH shuttles mediate the transfer of the reducing equivalents of the cytosolic NADH into mitochondria. Cumulating evidence...

The objective of the study was to investigate the in vitro antioxidation activity of lycium barbarum polysaccharides (LBP). Ultraviolet spectrophotometry was adopted to determine the capability of LBP to clear superoxide anions, hydroxyl radicals, DPPH free radicals and ABTS free radicals. The result showed that the law for LBP to clear superoxide anions, hydroxyl radicals and DPPH free radical...

Crude extracts of Sedum formosanum N.E.Br. obtained from n-butanol partition (BP) and isopropanol salting-out pretreatment (ISP) were analyzed using antioxidation assays. The results indicated that the extract from ISP contained more potent antioxidants and thus exhibited more antioxidant activity in all the assays. The superoxide radical-scavenging activity and inhibition of nitric oxide radic...
