Measurements Of Phospholipases A2, C And D (Pla2, Plc And Pld) : In Vitro Microassays, Analysis Of Enzyme Isoforms, And Intact-Cell Assays, Ramadan I. Sha’Afi
UCHC Articles - Research
Phospholipases have been studied in great detail and their role in cell signaling has been established in the last 20 years. A role for phospholipases in mitogenesis has been described in terms of the products of their enzymatic reactions. Lysophosphatidic acid (LPA) is produced by the action of a phosphatidic acid (PA)-specific phospholipase A2 (PLA2). LPA is a potent mitogen for quiescent fibroblasts and triggers GTP-dependent phosphoinositide breakdown (1) through a membrane receptor (2). A phosphatidylcholine-specific PLA2 is responsible for the release of arachidonic acid in response to cell stimulation. Arachidonic acid is the precursor of biologically-active eicosanoids such as …

Physical Wellness: The Relationship Between Motor Skill, Fitness And Physical Activity In Young Children, Beth P. Hands, Helen Parker
Physical Wellness: The Relationship Between Motor Skill, Fitness And Physical Activity In Young Children, Beth P. Hands, Helen Parker
Health Sciences Conference Papers
The health benefits of adequate physical activity levels for children are well reported. However, we cannot assume that children will choose to be sufficiently active of their own accord. Motor competence and fitness are increasingly highlighted as key co-determinants of physical activity in young children (Hands, Parker, & Larkin, 2001) and where possible strategies to enhance these factors should be included in early childhood settings. However few studies have adopted an integrated view of the collective effects of these three factors on developing healthy children. This presentation explores interrelationships between measures of motor skill competence, fitness, and weekly physical activity …

Nursing Faculty Research Publications
The purpose of this study was to determine the level of functional health literacy in a sample of patients treated in 1of our 5 primary care clinics. A total of 92 randomly selected adults (mean age = 59 years) completed the TOFHLA while waiting for a scheduled appointment. Twenty eight percent of the sample had less than adequate levels of functional health literacy. Income, car ownership and education were significant and independent predictors of literacy level in this sample. Low levels of functional health literacy limit a patient's ability to read, understand and act on health information. It is essential …

BACKGROUND
In preclinical and phase 2 studies, adefovir dipivoxil demonstrated potent activity against hepatitis B virus (HBV), including lamivudine-resistant strains.
METHODS
We randomly assigned 515 patients with chronic hepatitis B who were positive for hepatitis B e antigen (HBeAg) to receive 10 mg of adefovir dipivoxil (172 patients), 30 mg of adefovir dipivoxil (173), or placebo (170) daily for 48 weeks. The primary end point was histologic improvement in the 10-mg group as compared with the placebo group.
RESULTS
After 48 weeks of treatment, significantly more patients who received 10 mg or 30 mg of adefovir dipivoxil per day than …

Severity Message From Hazard Alert Symbol On Caution Signs, Roger C. Jensen, Andrew M. Mccammack
Safety Health & Industrial Hygiene
Standards for the design of signal word panels specify different combinations of colors, signal words, and a hazard alert symbol. The warning sign standards of the American National Standards Institute specify a yellow signal word panel, with the word Caution and a hazard alert symbol, for signs marking people hazards. The same panel, without the symbol, is intended for property hazards. The purpose of this study was to determine if the presence or absence of the symbol effectively conveys the intended severity messages. A sample of 59 college students rated their impressions of a Caution sign with and without the …

Synergistic Interactions Of Chlorambucil, Dha, And Trail In Jurkat And H460 Human Cancer Cells, Jennifer Ellen Bush-O'Donnell
Theses, Dissertations and Capstones
Traditional chemotherapeutic drugs are prone to toxicity and may result in secondary cancers. In recent years much attention has been garnered by alternate methods of cancer treatment with fewer side effects, including immunotherapy and administration of ω-3 fatty acids, both of which have been shown to cause apoptosis in cancer cells. Docosahexaenoic acid (DHA), a fatty acid, is a normal component of cell membranes and is safe for systemic administration. The cytokine TRAIL (tumor necrosis factorrelated apoptosis-inducing ligand) is able to induce apoptosis in cancer cells while sparing normal tissue. In this study, the alkylating agent chlorambucil (CLB) was combined …

Correlation Between Time To Peak Torque And Peak Torque To Vertical Jump In College Age Athletes, Craig Adam Kowalski
Correlation Between Time To Peak Torque And Peak Torque To Vertical Jump In College Age Athletes, Craig Adam Kowalski
Theses, Dissertations and Capstones
The vertical jump is an essential part of athletics to gain an advantage over the opponent. Isokinetic testing provides quantitative data to determine power and how fast power or peak torque is achieved. In this study, after 20 NCAA Div. II athletes were measured for three trials of maximal vertical jump, they completed an isokinetic test of knee extension at speeds of 60, 180, and 300°/sec. The results showed a significant correlation (p<0.05) between peak torque at a speed of 300°/sec and vertical jump p<=0.019. As a result of this study it was found that the vertical jump test is a test of muscle power generated by the quadriceps muscle group, and relates to peak torque values documented by isokinetic testing at 300°/sec of knee extension.

Detection Of Forces And Body Load In Standing And Walking In The American Cockroach, J. Adam Noah
Theses, Dissertations and Capstones
Sense organs in the legs that detect body weight are an important component in the regulation of posture and locomotion. This thesis seeks to gain an understanding of how body weight is detected by sense organs of the legs, and determine how this information influences muscle activities in standing and walking. The first study tested the ability of tibial campaniform sensilla (receptors that monitor forces in the cockroach leg) to encode variations in body load using magnets attached to the thorax. Recordings of sensory activities in freely standing animals showed that proximal tibial sensilla (oriented perpendicular to the leg long …
Phosphoproteomic Studies Of Smooth Muscle Contraction: Investigation Of Differential Phosphorylation In Relaxed/Contracted Rat Aortic Smooth Muscle Tissue Using Maldi-Tof Ms, Tonya M. Pekar
Theses, Dissertations and Capstones
Many human disorders are associated with the malfunction of smooth muscle tissue, or are related to the capabilities of its proper function—asthma, glaucoma, renal inefficiency, hypertension, and cardiovascular disease. Dysfunctional proteins are frequently implicated as the source of such disorders. As the second highest cause of death in the United States, the epidemic of cardiovascular disease makes the study of smooth muscle of utmost concern.
The capabilities of proteomics and mass spectrometry allow the entire proteome complement of a cell or tissue type to be analyzed at once. This investigation employs such techniques in an effort to better understand the …

The Characterization Of Two Differentially Expressed Plasma Proteins In Obese Versus Lean Rats In Two Rodent Models Of Obesity, Roger D. Boggs
Theses, Dissertations and Capstones
Zucker fa and La/N faf rats are widely studied models of genetic obesity and its complications. These two rodent models of obesity were utilized to search for a circulating protein marker for obesity. Plasma samples from both of these models of obesity were collected and analyzed via SDS-PAGE analysis. Two proteins were found which demonstrate differential expression between lean and obese rats. Both proteins demonstrated increased expression in the obese rats compared to the lean. One differentially expressed protein migrated on SDS-PAGE gels at 116 KD while the second migrated at 22 KD compared to molecular weight markers. The 22 …
Expanding Self-Direction In Services For The Aged And People With Disabilities, Ruth A. Burgess
Expanding Self-Direction In Services For The Aged And People With Disabilities, Ruth A. Burgess
Theses, Dissertations and Capstones
Medicaid-funded long-term care services are traditionally delivered in nursing homes. States may apply for waivers which allow them to provide home and community based services with Medicaid funds. Because these services are by definition an alternative to nursing home care, waiver services are generally based upon a medical model which emphasizes medical deficits and tends to restrict consumers’ movements to inside the home. Recent developments such as the Olmstead Decision and federal New Freedom Initiatives have caused states to recognize that consumers desire and have a legal right to be part of a community rather than institutionalized or homebound. These …

A Rural Hospital's Organ Donation Referral Pattern : A Pilot Study, Chris F. Carter
Theses, Dissertations and Capstones
It is unclear if hospitals correctly refer all potential organ donors to Organ Procurement Organizations. Unidentified or mis-referred patients may be present in rural acute care Appalachian hospitals. A one-year nonexperimental retrospective descriptive study was used to review medical records in one rural Appalachian hospital. Data from the chart review indicated that of the total (n = 34) patients, sixty-eight percent (n = 23) were properly referred as cardiac standstill and six percent (n = 2) were properly reported as brain dead. However, nine percent (n = 3) were not referred to the OPO (unidentified). Eighteen percent (n = 6) …
A Mechanistic Study In The Nephrotoxicity Of P-Aminophenol, R. Christopher Harmon
A Mechanistic Study In The Nephrotoxicity Of P-Aminophenol, R. Christopher Harmon
Theses, Dissertations and Capstones
The acetaminophen metabolite, p-aminophenol (PAP), is a known nephrotoxicant. The current study is directed at understanding the mechanism of this nephrotoxicity. Renal cortical slices isolated from F344 rats were incubated with 0 – 0.5 mM PAP with or without pretreatments. Renal slices exposed to PAP showed toxicity as measured by increased lactate dehydrogenase leakage (LDH), decreased pyruvate-stimulated gluconeogenesis, and decreased total adenine nucleotides. There was, however, an increase in ATP as percent of total, implying maintained mitochondrial function. These data show that PAP is directly toxic to renal cortical slices. Pretreatment with EDTA or EGTA provided protection from PAP- induced …
