Growing consumer interest in grass-fed beef products has raised a number of questions with regard to the perceived differences in nutritional quality between grass-fed and grain-fed cattle. Research spanning three decades suggests that grass-based diets can significantly improve the fatty acid (FA) composition and antioxidant content of beef, albeit with variable impacts on overall palatability...

UNLABELLED Venous bypass grafts are more prone to accelerated atherosclerosis than arterial grafts, which is partly related to increased oxidative stress and diminished nitric oxide bioavailability. In veins superoxide production is dependent primarily on nox2 NAD(P)H oxidase expression, while in arteries nox4 appears to play an important role. This may in part explain differences in susceptibi...

salinity of soil and irrigation water creates major problems for forage production. this study was aimed to evaluate the quality and quantity of forage production in intercropping of kochia (kochia scoparia l.) with blue panic grass (panicum antidotale retz.) under irrigation with saline water (4.9 ds.m-1). the study was performed based on randomized complete block design with three replication...

Tall fescue (Festuca arundinacea Schreb) is a typical cool-season grass that is widely used in turf and pasture. However, high temperature as an abiotic stress seriously affects its utilization. The objective of this study was to explore the effect of spermidine (Spd) on heat stress response of tall fescue. The samples were exposed to 22°C (normal condition) or 44°C (heat stress) for 4 h. The r...

crested wheatgrass (agropyron cristatum (l.) gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. the main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of iran as low-maintenance turfgrass. the experimental design was a randomized complete block design with 3 re...

Kentucky bluegrass can produce quality fairways in the Midwest if it is not mowed too short. Keep track of research. Climates vary widely across the Midwest, complicating the choice of fairway turf grass species. New epidemics of gray leaf spot have weakened the popularity of perennial ryegrass, long a preferred fairway species in many parts of the Midwest. Cultivars are available that accentua...

The production of superoxide (O2-) under hyperoxic conditions is markedly accentuated leading to the generation of potent oxidants such as hydrogen peroxide (H2O2), hydroxyl radical (HO.), and peroxynitrite (ONOO-). Superoxide dismutase (SOD), by rapidly removing O2-, reduces the tissue concentration of O2- and prevents the production of HO. and ONOO-. Three forms of SOD exist in the lung: CuZn...

Turf wars in organizations commonly occur in environments where competition undermines collaboration. We develop a game theoretic model and experimental test of turf wars. The model explores how team production incentives ex post affect team formation decisions ex ante. In the game, one agent decides whether to share jurisdiction over a project with other agents. Agents with jurisdiction decide...
