| Although cardiac ischemia is usually characterized as a disease of the myocyte, it is clear that the vasculature, and especially endothelial cells, is also a major target of this pathology. Indeed, using a rat model of ischemia/reperfusion, we were able to detect severe endothelial dysfunction (assessed as a decreased response to acetylcholine) after acute or chronic reperfusion. Given the essential role of the endothelium in the regulation of vascular tone, as well as platelet and leukocyte function, such a severe dysfunction could lead to an increased risk of vasospasm, thrombosis and accelerated atherosclerosis. This dysfunction can be prevented by free radical scavengers and by exogenous nitric oxide. Endothelial dysfunction can also be prevented by... |

| Excessive consumption of alcoholic beverages is a serious cause of liver disease worldwide. The meta-bolism of ethanol generates reactive oxygen species, which play a significant role in the deterioration of alcoholic liver disease (ALD). Antioxidant phytochemicals, such as polyphenols, regulate the expression of ALD-associated proteins and peptides, namely, catalase, superoxide dismutase, glutathione, glutathione peroxidase, and glutathione reductase. These plant antioxidants have electrophilic activity and may induce antioxidant enzymes via the Kelchlike ECH-associated protein 1-NF-E2-related factor-2 pathway and antioxidant responsive elements. Furthermore, these antioxidants are reported to alleviate cell injury caused by oxidants or inflammatory... |

| Objectives were twofold: Determine key factors influencing preconditioning cost and returns; and determine the premium for age and source verified, preconditioned calves sold at a public livestock market. Data provided by the Samuel Roberts Noble Foundation show preconditioning returns depend significantly on number of days preconditioned, average daily gain, and cost of vaccinations, hay, feed, and mineral. Noble Foundation cooperators received a premium for age and source verified, preconditioned feeder cattle when sold at market. Significant coefficients averaged across five sales conclude that Noble Foundation management practices receive a $2.49/cwt premium when compared to all other cattle sold at market. |

| Many value-added practices cannot be observed by feeder cattle buyers. Third-party verification can decrease market inefficiency associated with this asymmetric information. We evaluate the effectiveness of a verification program, the Oklahoma Quality Beef Network, in increasing received prices. We estimate the value of verification, weaning, vaccinating, certification and phenotypic traits of feeder cattle at Oklahoma auctions. Results indicate that the OQBN program adds $2.39 to $5.74/cwt. Vaccinating calves adds $1.44/cwt, and weaning calves adds $2.05/cwt. Differential values for lot size, average weight, hide color, frame size, conditioning, Brahman influence, gender and other characteristics are also reported. |
