Mechanics And Modeling Of Postnatal Arterial Development In Mouse Models Of Varying Elastin, Jeffrey Karl Cheng

All Theses and Dissertations (ETDs)

Proper arterial function requires a specific composition of extracellular matrix: ECM) proteins to produce a vessel with the right mechanical properties. Closed circulatory systems driven by a beating heart have pulsatile flow, requiring the large elastic arteries to have the ability to distend and recoil to dampen the pulsatile output. This unique ability is made possible by elastin in the ECM that imparts elastic behavior to the artery. Genetic mutations that affect the amount and organization of elastin result in congenital cardiovascular defects that lead to lifelong cardiovascular complications. In order to devise proper treatments we must understand how development …

Humanitarianism And The Anthropology Of Hunger, Kate Klein

Undergraduate Theses—Unrestricted

While the early view of hunger as the product of a world population too large to sustain has largely been eliminated, and the mainstream international community has come to accept that food insecurity results from issues of distribution rather than an insufficient global food supply, the emphasis on biotechnology in agriculture, humanitarianism in international aid, and social justice in international human rights law in the contemporary era has contributed to other barriers that prevent hunger alleviation.

In this thesis, I argue that these previous contemporary developments have had the capacity to hide hunger. My analysis of technology and humanitarian aid …

Growing Up Tamarin: Morphology, Reproduction, And Population Demography Of Sympatric Free-Ranging Saguinus Fuscicollis And S. Imperator, Mrinalini Watsa

All Theses and Dissertations (ETDs)

The Callitrichidae are family of small New World primates with a suite of distinctive morphological and behavioral adaptations that set them apart from other primates. Of primary interest is their reproductive system that includes compulsive twinning: ≥80% of births) and cooperative care of offspring by individuals other than biological parents: termed alloparenting). Further, hematopoietic tissues in callitrichids display signals of both self and sibling DNA, due to an exchange of stem cells early in gestation that renders twin callitrichids as cellular mosaics of each other. This phenomenon is known as genetic chimerism, which increases genetic relatedness between individuals and is …
