Effects Of Glucocorticoids Upon Pro-Inflammatory Responses To Acute Sleep Fragmentation, Hunter Weaver
Effects Of Glucocorticoids Upon Pro-Inflammatory Responses To Acute Sleep Fragmentation, Hunter Weaver
Masters Theses & Specialist Projects
Sleep loss is a common problem in humans who suffer from obstructive sleep apnea. Sleep aids in the regulation of immune responses, some of which induce inflammatory responses. Cytokines regulate the inflammatory process and are released in response to sleep fragmentation (SF) in mice. Glucocorticoids are hormones that are released from the adrenal cortices during a stress response and are considered to be anti-inflammatory and immunosuppressive at high doses but may stimulate immune function on an acute level. The first hypothesis tested was that normal physiological expression of glucocorticoids (Sham) will display increased IL-1β and TNFα expression levels, while high …
Contribution Of A Putative Up Element Dna Sequence To The Activity Of A Newly Identified Phage Promoter, Courtney Hamilton
Contribution Of A Putative Up Element Dna Sequence To The Activity Of A Newly Identified Phage Promoter, Courtney Hamilton
Mahurin Honors College Capstone Experience/Thesis Projects
In transcription, a universal step in gene expression, information from a DNA sequence is copied into RNA. A key component in gene expression is the promoter sequence, a region of DNA to which RNA polymerase binds during the initiation of transcription of downstream genes. Most bacterial promoters contain a -10 and a -35 sequence that are bound by the RNA polymerase. Some promoters also contain an Upstream Promoter (UP) element. UP elements have been shown to boost promoter activity. We recently identified a new promoter in a mutant bacteriophage that grows on a bacterial host that prevents antitermination of phage …
Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush
Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush
Masters Theses & Specialist Projects
The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perform the same intensity rotation (Counter …
Cloning Of A Chlamydomonas Reinhardtii Marker Into A Rna Interference Construct To Test Whether The Photoreceptor Chlamyrhodopsin Is Involved In Circadian Clock Resetting, Shravya Reddy Maddi
Cloning Of A Chlamydomonas Reinhardtii Marker Into A Rna Interference Construct To Test Whether The Photoreceptor Chlamyrhodopsin Is Involved In Circadian Clock Resetting, Shravya Reddy Maddi
Masters Theses & Specialist Projects
Chlamydomonas reinhardtii, a unicellular eukaryotic green alga, serves as a model organism to study the circadian clock in plants and animals. Rhodopsins are blue/green-light photoreceptors also found in C. reinhardtii. Chlamyrhodopsin (COP), the most abundant eyespot protein, was reported to have no role in the phototactic and photophobic responses in C. reinhardtii. Its function is yet unknown.
In the present study, we hypothesized that the function of COP is to mediate entrainment of the circadian clock by light. In order to test this hypothesis, a C. reinhardtii selection marker conferring resistance to the antibiotic paromomycin was cloned …
Caffeine Supplementation And Moderate Intensity Exercise Modulates The Cytotoxic Lymphocyte Subset (Cd+8) In Naive And Tolerant Individuals, Elizabeth Ann Fedor
Caffeine Supplementation And Moderate Intensity Exercise Modulates The Cytotoxic Lymphocyte Subset (Cd+8) In Naive And Tolerant Individuals, Elizabeth Ann Fedor
Masters Theses & Specialist Projects
The purpose of this investigation was to determine the effects of caffeine supplementation on caffeine tolerant and caffeine naïve individual’s lymphocyte counts, apoptosis and migration levels. In addition, effects of exercise on post-caffeine ingestion lymphocyte counts, apoptosis and migration levels were determined. It was hypothesized that caffeine would alter the immune system cell counts, but that exercise would be able to restore the immune system to homeostasis. Seventeen Western Kentucky University students were tested (males n=7, females n=10; n=7: caffeine tolerant= 200mg or more per day group, n=9: caffeine naïve= 50mg or less per day group). In this double-blind investigation, …

Southern Lagoon And Village Of Gales Point, Belize, Ca: Water Uses, Water Quality, And Potential Health Impacts, Rasmi Nair, Ritchie Taylor
Southern Lagoon And Village Of Gales Point, Belize, Ca: Water Uses, Water Quality, And Potential Health Impacts, Rasmi Nair, Ritchie Taylor
Impact Belize
An International Health Service Learning Program, Impact Belize 2010, was conducted by Western Kentucky University. Faculty and students worked closely with Gales Point villagers to gain an insight into the use of Southern Lagoon. The objective of the study was to assess fecal coliform levels in Southern lagoon, its primary and secondary contact use by villagers and its potential impact on health. Study methodology involved collection of water samples, both near shore and offshore, in the lagoon and incubating them using ColiQuant EZ method approved by EPA. A questionnaire was administered to villagers attending the WKU clinic to collect data …

An Analysis Of Illegal Bushmeat Availability In Local Restaurants Located In Voi, Kenya, Bridget A. Sutton
An Analysis Of Illegal Bushmeat Availability In Local Restaurants Located In Voi, Kenya, Bridget A. Sutton
Masters Theses & Specialist Projects
The illegal bushmeat harvest has been identified as a reason for declining wildlife populations throughout much of Africa. For many years the trade was thought to exist primarily in Western Africa. The illegal use of bushmeat in Eastern Africa, including Kenya, went undocumented and unstudied. In 2004, the Born Free Foundation published a study which claimed illegal sale of wild game was substantial in butcheries throughout Nairobi, Kenya. In an effort to determine other markets of the commercial trade, the goal of this study was to analyze local restaurants in Voi, Kenya for illegal bushmeat sale. The town of Voi …

The Effect Of Orally Administered Butylated Hydroxytoluene On Herpes Simplex Keratitis, Donald Carson
The Effect Of Orally Administered Butylated Hydroxytoluene On Herpes Simplex Keratitis, Donald Carson
Masters Theses & Specialist Projects
Some studies have reported in vitro inactivation of membrane enveloped viruses by Butylated hydroxytoluene (BHT). This study investigates the effect of orally administered BHT on primary infections of Herpes simplex virus (HSV) using rabbit corneas as the assay system.
Assigned levels of BHT were incorporated into the diet of New Zealand White rabbits with HSV-1 McKrae strain on the corneal surface of the eyes. The degree of infection was measured by a subjective assay. Rabbits receiving BHT in their diet consistently experienced lower levels of infection. The interpretation of this data is that orally administered BHT can be an effective …
