Caveolin-1 Recruitment To The Trailing Edge Of Motile Cells Results In Focal Adhesion Disassembly And Nascent Interaction With Actin Stress Fibers, Andrew Beardsley

Graduate Theses, Dissertations, and Problem Reports (ETD)

The protein caveolin-1 has been shown to positively affect angiogenesis and vascular remodeling in vivo via studies using knockout mice. In fact, defects in these two processes are among the major hallmarks of an otherwise benign caveolin-null phenotype. Current dogma on the function of caveolin-1 does not predict or account for these deficits. The overall objective of the following studies was to uncover the role of caveolin-1 in angiogenesis and vascular remodeling through study of the protein in cell-substratum remodeling during cell motility in vitro.;In the first study, caveolin-1 and its parent organelle, caveolae, conspicuously polarize to the rear of …

Communicative Functions Of Young Children's Visual Art, Clover Simms Wright

Graduate Theses, Dissertations, and Problem Reports (ETD)

How can young children use visual art to communicate? This study used Halliday's communicative functions of language (Halliday, 1973), to frame the answer to this question; Halliday's categories of communicative functions are: instrumental, regulatory, interactional, personal, heuristic, imaginative, and representational/informative. Five children, between the ages of three and five, were observed and interviewed as they voluntarily created visual art over a six-week period. In that time period, each of the seven functions of language was demonstrated collectively by the participants. The research was conducted by an educator employed in the early childhood setting. Qualitatively, this study confirmed that young children …

The Use Of Chickens To Remove The Infective Stage Of Haemonchus Contortus From The Field After Sheep Have Grazed, Jessica Harley Nicole Eddy

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are few USDA organic certified practices for controlling the nematode Haemonchus contortus. This small ruminant parasite has a life cycle that makes it a candidate for control using field rotations. The third-stage of the nematode's life cycle is responsible for infecting or re-infecting a host and the use of chickens to control H. contortus has not been tested. This experiment was conducted to determine if the chicken's foraging behavior reduces the number of infective third-stage larvae on the pasture by comparing a chicken sub-plot, a sub-plot that was mowed, a control sub-plot and a pretreatment. These forage removal methods …

Hemodynamics Of Intracranial Aneurysms: Factors That May Influence Occurrence, Francisco Adolfo Pino Romainville Dec 2008

Hemodynamics Of Intracranial Aneurysms: Factors That May Influence Occurrence, Francisco Adolfo Pino Romainville

Graduate Theses, Dissertations, and Problem Reports (ETD)

The formation and growth of intracranial aneurysms are partly attributed to various hemodynamic factors, such as the wall shear stress and pressure. However, the exact nature of the hemodynamic variables responsible for triggering aneurismal growth is still unknown. The conclusions drawn by various studies in this regard are found to be speculative and sometimes ambiguous. This issue is further investigated in the present work using some new insight gained from passive scalar dispersion in the blood flow for realistic aneurysm geometries. Intracranial aneurysms are best visualized using selective catheter angiogram technique where a contrast agent added to the blood flow …

Association Of Changes In Norepinephrine And Serotonin Transporter Expression With The Long-Term Behavioral Effects Of Antidepressant Drugs, Zaorui Zhao

Graduate Theses, Dissertations, and Problem Reports (ETD)

The relationship between the ability of repeated antidepressant treatment to cause down-regulation of the norepinephrine and serotonin transporters (NET, SERT) and produce antidepressant-like effects on behavior was determined. Treatment of rats with 15 mg/kg/day desipramine reduced NET expression, measured by 3H-nisoxetine binding and SDS-PAGE/immunoblotting, in cerebral cortex and hippocampus and reduced the time of immobility in the forced-swim test. The antidepressant-like effect on forced-swim behavior was evident two days following discontinuation of desipramine treatment when plasma and brain levels of desipramine and its major metabolite desmethyldesipramine were not detectable. Reduced NET expression resulted in decreased norepinephrine (NE) uptake, measured in …

Effects Of A Mind-Consciousness-Thought (Mct) Intervention On Stress And Well-Being In Freshman Nursing Students, Judith A. Sedgeman May 2008

Effects Of A Mind-Consciousness-Thought (Mct) Intervention On Stress And Well-Being In Freshman Nursing Students, Judith A. Sedgeman

Graduate Theses, Dissertations, and Problem Reports (ETD)

An emerging "health" paradigm, Mind-Consciousness-Thought (MCT), proposes that three universal Principles, Mind (life energy), Consciousness (the capacity to be aware of thinking as "reality"), and Thought (the ability to create thinking continually), explain how psychological experience is created from the inside-out, not created from the outside-in by events and circumstances. It proposes that life comes through us, not at us. It proposes that insight into the existence and operation of those principles reconnects people to their innate mental well-being, an always accessible source of balance, wisdom, and creativity (i.e., resiliency). It proposes that accessing mental well-being is incompatible with chronic …

Periconceptional Treatment With Growth Hormone Alters Fetal Growth And Development In Sheep, Jill Marie Koch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Altering the fetal environment can modify the composition or growth rate of the fetus, a concept known as fetal programming. A majority of the research in this area has focused on intrauterine growth restriction (IUGR), which has been linked to adult diseases. A few studies have attempted to ameliorate the negative effects of IUGR, by applying growth promoters late in gestation, and have only observed transient effects. Our laboratory has previously shown that growth hormone (GH) treatment around the time of breeding alters the uterine environment early in gestation and results in larger lambs at birth. Therefore there were three …
