Arteriogenic Revascularization Does Not Induce Vascular Function Impairment, Matthew David Yocum
Master's Theses
Functional hyperemia and arteriolar vasodilation are impaired with chronic ischemia. We sought to examine the impact of chronic ischemia on collateral artery function. For this we used two hindlimb ischemia models to dissect the impact of different repair processes on collateral function. Ligation of the femoral artery increases shear stress in the muscular branch and results in outward remodeling and arteriogenesis. In contrast, resection of the femoral artery proximal to the muscular branch induces blood flow divergence and neutral remodeling along with expectedly greater hypoxia and inflammation. On day 14 after each surgery the diameter of the muscular branch was …

Group Feeding For The Lactating Cow, Anthony Joseph Martin
Dairy Science
Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …
