This study was performed to assess the antioxidant activity of Allium hookeri root extract (AHE) on lipid oxidation of raw sulfur-fed pork patties for 14 d of refrigerated storage. Different concentration of ethanol (0-100%) and time (1-12 h) were applied to determine the extraction condition. Water (0% ethanol) extraction for 1 h was selected as an optimal extraction condition of AHE for the f...
This study investigated the effects of supplementation with Krill oil on levels of pro-oxidant/antioxidant balance markers and levels of pro-inflammatory cytokines in professional rowers submitted to exhaustive exercise. This double-blind study included 17 members of the Polish National Rowing Team. Subjects were randomly assigned a supplemented group (n=9) which received two capsules (500 mg) ...
INTRODUCTION Oxidative lung damage may be associated with the destruction of alveolar cells. Type II alveolar epithelial cells (AECs),as progenitors of type I cells, are indispensable for the renovation of alveolar structure after lung injury. Extensive damage to type II cells could be responsible for unfavorable outcome. However, the susceptibility of type II AECs to oxidative stress is unclea...
Reactive oxygen species (ROS) are common products of the physiological metabolic reactions, which are associated with cell signaling and with the pathogenesis of various nervous disorders. The brain tissue has the high rate of oxidative metabolic activity, high concentration of polyunsaturated fatty acids in membrane lipids, presence of iron ions and low capacity of antioxidant enzymes, which m...
BACKGROUND Salivary thiobarbituric acid reacting substances (TBARS) have been previously shown to correlate with the impairment of gingival tissue. Although the details on the origin and the composition of this heterogeneous group of compounds in saliva are unknown, the potential clinical usefulness makes necessary the studies of factors influencing the salivary TBARS levels. AIM To observe t...
A natural product such as chitosan promotes health benefits and extends the shelf life of processed products. Chitosan has been used a food additive due to its antioxidant antimicrobial activities. This study was conducted optimize concentration coating agent on quality Labeo rohita fillets during frozen storage. (CH) solutions were prepared with 0.5 %, 1 2 % (w/v) CH in (v/v) glacial acetic ac...
The aim of this study was to analyze the impact three concentrations a pesticide mixture on first development stages rainbow trout (Oncorhynchus mykiss). made up commonly used pesticides in viticulture: glyphosate (GLY), chlorpyrifos (CPF) and copper sulfate (Cu). Eyed stage embryos were exposed for 3 weeks mixture. Lethal sub-lethal effects assessed through number phenotypic molecular endpoint...
background: activation of inflammatory cells can cause more chemicals induced-hepatotoxicity. aflatoxin b1 (afb1) is a fungal toxin that induces acute hepatotoxicity in humans and animals. this study was conducted to examine the effect of co-exposure lps and various aflatoxin b1 doses on the damage hepatic parameters in isolated perfused rat liver. methods: thirty-two male wistar rats (250-300g...
The one pot reactions carried among salicylaldehyde 1, ortho-aminophenols 2a-2g, and di-phenyl-tin(IV) oxide 3 led to seven di-phenyl-tin(IV) compounds 4a-4g in good yields (97-83%). All compounds were analyzed by IR, 1H, 13C, 119Sn NMR spectroscopy, mass spectrometry and elemental analyses; furthermore, in the case of compounds 4b, 4c, 4e and 4g by X-ray diffraction. Compounds 4a-4g were teste...
Different packaging is available to consumers, and marination is widely applied. However, their effects on the quality of broiler breast fillets during home freezing are not well known to consumers. Therefore, the objective of this study was to evaluate the effect of packaging materials on the quality of chicken breast fillets after 1, 3, and 6 wk storage at -18°C. A total of 256 fillet were ra...
