Acute Exercise And Its Effect On Cognitive Performance In Sleep Deprived Individuals: A Review Of Literature., Jennifer Nicole Miller Dec 2012

Acute Exercise And Its Effect On Cognitive Performance In Sleep Deprived Individuals: A Review Of Literature., Jennifer Nicole Miller

Undergraduate Honors Theses

This literature review observes seven different studies that researched the effects of exercise on some measure of cognitive or psychological performance when sleep deprived. The purpose of this review is to consolidate the results of various exercise protocols on the effects of sleep deprivation to make a general conclusion regarding the effect on cognition. This will give insight into the future of research regarding how exercise may combat performance decrements seen when sleep deprived. There are several inconsistencies among current research concerning exercise and sleep deprivation; a standard needs to be created so the results of these studies can be …


Localization And Expression Of Gfrα2 Receptors In Neonatal And Adolescent Mouse Heart., Bryan Gunter May 2012

Localization And Expression Of Gfrα2 Receptors In Neonatal And Adolescent Mouse Heart., Bryan Gunter

Undergraduate Honors Theses

Neurturin (NRTN), a member of the glial cell-line derived neurotrophic factor(GDNF) family, is required in the development of parasympathetic cholinergic neurons. It signals through binding to a glycosyl-phophatidyl inositol (GPI)-linked receptor, GDNF family receptor α2 (GFRα2), which couples to Ret tyrosine kinase. Studies of NRTN knockout mice have shown that NRTN is essential for normal cholinergic innervation of the heart, but the precise role of NRTN remains unknown. For NRTN to evoke a biological response, GFRα2 must be localized to the surface of target neurons. The aim of this study was to determine the expression and localization of GFRα2 at …


Effects Of Microgravity On Mucin Production In The Urinary Bladder In Mice., Brandon Farmer May 2012

Effects Of Microgravity On Mucin Production In The Urinary Bladder In Mice., Brandon Farmer

Undergraduate Honors Theses

The effects of the microgravity of spaceflight are largely unexplored with regard to biological tissues. One particular area of interest is the possible effects microgravity could have on the production of mucins. To determine the possible effects of microgravity on mucin production in the urinary bladder, we examined the transitional epithelium of the urinary bladder from female mice that were flown on the space shuttle Endeavour for 12 days in August, 2007. The flight tissue was compared to tissues from two control groups of animals, ground control and baseline. This study utilized three sets of female mice, with each set …
