Relationships Among Rubus (Rosaceae) Species Used In Traditional Chinese Medicine, Yinu Wang Aug 2011

Relationships Among Rubus (Rosaceae) Species Used In Traditional Chinese Medicine, Yinu Wang

Masters Theses & Specialist Projects

Traditional Chinese medicine has a long history of using plants therapeutically including multiple species of the genus Rubus (Rosaceae). Fruits and other parts of Rubus plants have had a significant effect on human health and nutrition in both ancient and modern times. The pharmacological effects of Rubus include anti-inflammatory, antibacterial, anti-stress, anti-cancer and anti-aging properties. One of the current challenges limiting further development of Rubus resources in traditional Chinese medicine is a poor understanding of phylogenetic relationships among Rubus species in general and especially among Asian species, and also the need for additional studies of phytochemicals. Several confounding factors are …


Action Spectrum For Photoentrainment Of The Circadian Clock In Wild-Type Chlamydomonas Reinhardtii, Jennifer Forbes=Stovall Aug 2011

Action Spectrum For Photoentrainment Of The Circadian Clock In Wild-Type Chlamydomonas Reinhardtii, Jennifer Forbes=Stovall

Masters Theses & Specialist Projects

The circadian clock is an endogenous timer that oscillates with a period of approximately 24 hours and is reset upon environmental time cues such as the daily light/ dark or temperature cycles. Chlamydomonas reinhardtii is an ideal model organism for research on the circadian clock, because it shows several well-characterized behaviors that exhibit a circadian rhythm. Its circadian rhythm of phototaxis (swimming toward light) has been automated. Former action spectrum studies using the circadian phototaxis rhythm as an indicator surprisingly found that pulses of blue light were not effective in resetting the circadian clock of dark-adapted cells. This may have …


Comparison Of Workplace Protection Factors For Different Biological Contaminants, Kyungmin Jacob Cho, Tiina Reponen, Roy Mckay, Alok Dwivedi, Atin Adhikari, Umesh Singh, Rakesh Shukla, M. Susan Jones, Gordon Jones, Sergey A. Grinshpun Jun 2011

Nursing Faculty Publications

This study compared workplace protection factors (WPFs) for five different contaminants (endotoxin, fungal spores, (1→3)-β-D-glucan, total particle mass, and total particle number) provided by an N95 elastomeric respirator (ER) and an N95 filtering facepiece respirator (FFR). We previously reported size-selective WPFs for total particle numbers for the ER and FFR, whereas the current article is focused on WPFs for bioaerosols and total particle mass. Farm workers (n = 25) wore the ER and FFR while performing activities at eight locations representing horse farms, pig barns, and grain handling facilities. For the determination of WPFs, particles were collected on filters simultaneously …


The Proliferation Of Vascular Smooth Muscle Cells Depends On Thioredoxin 1 Protein In A Model Of Pulmonary Hypertension, Viktoria Nelin May 2011

The Proliferation Of Vascular Smooth Muscle Cells Depends On Thioredoxin 1 Protein In A Model Of Pulmonary Hypertension, Viktoria Nelin

Mahurin Honors College Capstone Experience/Thesis Projects

Pulmonary hypertension (PH) is a disease which manifests itself in the lungs of both adults and children. Vascular proliferation and remodeling are the hallmarks of PH and are found mainly in the pulmonary arterial smooth muscle cells (PASMC). The cause of PASMC proliferation and vascular remodeling in PH is poorly understood. Hypoxia, or low oxygen content, underlies many forms of PH. Hypoxia results in alterations in the redox balance of the PASMC. Therefore, the aim of this study was to examine the role of the thioredoxin system, an antioxidant system in the cell, in hypoxia-induced proliferation in PASMC. Protein was …


Assessment Of Prenatal Care And Perinatal Outcomes In Kasigau, Kenya, Allison Smith May 2011

Assessment Of Prenatal Care And Perinatal Outcomes In Kasigau, Kenya, Allison Smith

Mahurin Honors College Capstone Experience/Thesis Projects

The World Health Organization (WHO) implemented the Millennium Declaration in 2000 to establish global health goals to be achieved by 2015. Two of these Millennium Development Goals (MDG’s) are directly related to maternal, neonatal and child health. Healthcare during the prenatal period can help achieve the WHO MDG’s for maternal health and child mortality. Evidence has shown that women in Kenya have limited access to prenatal care. This study focused on the prenatal care and postnatal outcome trends of the women in Kasigau, Kenya. Participants were surveyed in three villages (Rukanga, Makwasinyi, and Bhuguta) to determine if prenatal care was …


Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush May 2011

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 …


A Prevalence Study Of Southeast Origin Sale Barn Beef Cattle, Comingled In Warren County, Kentucky, Persistently Infected With Bovine Viral Diarrhea Virus, Including The Effects Of Season And Body Weight, Sarah Elizabeth Thomas May 2011

A Prevalence Study Of Southeast Origin Sale Barn Beef Cattle, Comingled In Warren County, Kentucky, Persistently Infected With Bovine Viral Diarrhea Virus, Including The Effects Of Season And Body Weight, Sarah Elizabeth Thomas

Masters Theses & Specialist Projects

Bovine viral diarrhea (BVD) is an economically important disease of cattle. Calves persistently infected (PI) with the bovine viral diarrhea virus (BVDV) are a powerful agent for spread of the virus. A total of 24,423 southeast origin beef cattle comingled at three Warren County, Kentucky locations were tested from November 2007 to June 2010 for PI BVDV. A total of 97 head tested positive for PI BVDV, giving an average overall prevalence of 0.397%.
Calves tested were subdivided into categories for additional calculations of dependence. A total of 8,910 were categorized by weight range upon testing (300-399 lbs, 400-499 lbs, …
