Differential Roles Of The Two Major Endocannabinoid Hydrolyzing Enzymes In Cannabinoid Receptor Tolerance And Somatic Withdrawal, Joel Schlosburg Apr 2010

Differential Roles Of The Two Major Endocannabinoid Hydrolyzing Enzymes In Cannabinoid Receptor Tolerance And Somatic Withdrawal, Joel Schlosburg

Theses and Dissertations

While there is currently active debate over possible therapeutic applications of marijuana and cannabis-based compounds, consistently their primary drawbacks have been the psychoactive properties, dependence, and abuse potential. Prolonged administration of ∆9-tetrahydrocannabinol (THC), the primary psychoactive constituent in marijuana, demonstrates both tolerance and physical withdrawal in both preclinical and clinical studies. Repeated THC administration also produces CB1 receptor adaptations in the form of reduced activation of receptors, along with a downregulation of membrane surface receptors, in many brain regions involved in THC-associated behaviors. The increased need for drug to maintain therapeutic effects, and a withdrawal syndrome following discontinuation of use, …

Proteasome-Dependent Entry Of Herpes Simplex Virus, Mark Delboy Apr 2010

Proteasome-Dependent Entry Of Herpes Simplex Virus, Mark Delboy

Theses and Dissertations

Herpes simplex virus entry into cells is a multistep process that engages the host cell machinery. The proteasome is a large, ATP-dependent, multisubunit protease that plays a critical role in the maintenance of cell homeostasis. A battery of assays were used to demonstrate that proteasome inhibitors blocked an early step in herpes simplex virus entry that occurred after capsid penetration into the cytosol but prior to capsid arrival at the nuclear periphery. Proteasome-dependent viral entry was not reliant on host or viral protein synthesis. MG132, a peptide aldehyde that competitively inhibits the degradative activity of the proteasome, had a reversible …


Sensitivity Analysis – The Effects Of Glasgow Outcome Scale Misclassification On Traumatic Brain Injury Clinical Trials, Juan Lu Apr 2010

Sensitivity Analysis – The Effects Of Glasgow Outcome Scale Misclassification On Traumatic Brain Injury Clinical Trials, Juan Lu

Theses and Dissertations

I. EFFECTS OF GLASGOW OUTCOME SCALE MISCLASSIFICATION ON TRAUMATIC BRAIN INJURY CLINICAL TRIALS The Glasgow Outcome Scale (GOS) is the primary endpoint for efficacy analysis of clinical trials in traumatic brain injury (TBI). Accurate and consistent assessment of outcome after TBI is essential to the evaluation of treatment results, particularly in the context of multicenter studies and trials. The inconsistent measurement or interobserver variation on GOS outcome, or for that matter, on any outcome scales, may adversely affect the sensitivity to detect treatment effects in clinical trial. The objective of this study is to examine effects of nondifferential misclassification of …


The Influence Of Organizational Culture On The Existence Of Systems Employed To Improve Quality Of Care In Medical Office Practices, Donna Dugan Apr 2010

The Influence Of Organizational Culture On The Existence Of Systems Employed To Improve Quality Of Care In Medical Office Practices, Donna Dugan

Theses and Dissertations

A frequently cited reason for poor quality of care in the ambulatory care setting is the lack of optimally designed systems to address care for those with preventive or chronic care needs. Organizational theory suggests that culture plays an important role in the shaping of these types of programs. The purpose of this cross-sectional study is to understand through descriptive and regression analysis of secondary data, the relationship between the existence of cultural characteristics such as collegiality, quality emphasis and autonomy, and the systems employed to improve quality of care within primary care practices. The study uses an integrated theoretical …


Neuroprotection With Anesthetics In Two Models Of Cerebral Ischemia, Rafael Eduardo Chaparro Buitrago Apr 2010

Neuroprotection With Anesthetics In Two Models Of Cerebral Ischemia, Rafael Eduardo Chaparro Buitrago

USF Tampa Graduate Theses and Dissertations

Neuroprotection with anesthetics has been studied for many decades; important advances in this field have modified the way Anesthesiologists treat patients in the operating room. Animal models have played an important role in the study of ischemia in the operating room. Recent studies have demonstrated that the effect of anesthetics seems to be different in different animal models. We decided to evaluate anesthetics in a well-known model of cerebral ischemia and also in hypotensive models designed by us. We used a model of cerebral ischemia (MCAO) to test anesthetics neuroprotective effect in a two-week period. Then, we used a model …


Modulation Of Cocaine-Like Behavioural Activity By Serotonin Uptake Inhibition Relative To The Effects Of The Novel And Selective Dopamine Transporter Inhibitor, D-84, Angela Batman Apr 2010

Modulation Of Cocaine-Like Behavioural Activity By Serotonin Uptake Inhibition Relative To The Effects Of The Novel And Selective Dopamine Transporter Inhibitor, D-84, Angela Batman

Theses and Dissertations

Cocaine dependence is a major health concern worldwide, but despite this high rate of abuse there are currently no approved therapies for cocaine dependence. Replacement pharmacotherapies are one possible approach for treating cocaine dependence, and identification of such therapeutics for cocaine abuse is the long-term goal of this research. Cocaine binds to, and inhibits uptake at the dopamine (DAT), serotonergic (SERT) and noradrenaline (NET) uptake transporters, but studies have shown that cocaine produces its strong behavioural and positive reinforcing effects through inhibition of the DAT. To this end a great number of diverse, non-selective DAT-inhibiting compounds have been investigated as …


The Clinical Utility Of Molecular Typing Of Multiply-Resistant Pseudomonas Aeruginosa In Children With Cystic Fibrosis, Ruth Ann Luna Apr 2010

The Clinical Utility Of Molecular Typing Of Multiply-Resistant Pseudomonas Aeruginosa In Children With Cystic Fibrosis, Ruth Ann Luna

Theses and Dissertations

Chronic infection with P. aeruginosa is expected in patients with cystic fibrosis (CF), but the ability to delay, prevent, or better manage infection with multiply-resistant P. aeruginosa (MRPA) can potentially increase quality of life and extend survival. The Texas Children’s Hospital CF Care Center has identified an endemic MRPA strain (dominant clone), and this study aimed to identify risk factors for acquisition of the clone as well as determine differences in patient outcome associated with subsequent infection with the clone. The study included 71 patients with CF with documented MRPA infection. Designation of patients as members of the dominant clone …


Diagnosing Decisions: An Examination Of Medical Career Choices And Their Effects On The Health Care System, Nicole Craker '10 Apr 2010

Diagnosing Decisions: An Examination Of Medical Career Choices And Their Effects On The Health Care System, Nicole Craker '10

Honor Scholar Theses

With the passage of the new health care bill in March of this year, President Obama was able to promise health care coverage to millions of Americans (Health Reform, 2010). While this was a major step towards increasing the health of our nation, promise of coverage does not automatically equate with the promise of better health. Rather, the expanded coverage may more significantly correlate with expanded physician wait lists. As newly insured Americans attempt to make appointments, they may have a difficult time finding a physician who has the time to take them due to a shortage of available doctors. …


Living On Autopilot: How Your Brain Thinks For You, Andrea Stathopoulos '10 Apr 2010

Living On Autopilot: How Your Brain Thinks For You, Andrea Stathopoulos '10

Honor Scholar Theses

One way in which humans are set apart from other animals is by our impressive intellectual capacities. Humans are commonly considered to be true masters of rational, conscious control over our actions. However, that feeling of control may be mostly illusory. Accumulating evidence suggests that unconscious cognitive processes can account for much of human behavior. Homeostasis is a clear example of the evolutionary benefit of automation, allowing valuable energy and limited attention to be diverted elsewhere. I instead want to focus on the automaticity of more complicated behaviors, ones that are typically thought to require a large amount of cognitive …


Perifosine, A Novel Akt Inhibitor Induces Apoptosis, Cell Cycle Arrest And Has A Chemo-Sensitizing Effect In Medulloblastoma Cell Lines, Anil Kumar Apr 2010

Perifosine, A Novel Akt Inhibitor Induces Apoptosis, Cell Cycle Arrest And Has A Chemo-Sensitizing Effect In Medulloblastoma Cell Lines, Anil Kumar

Theses and Dissertations

Primary central nervous system (CNS) tumors are the most common solid tumors found in children. While surgery and radiotherapy still remain the standard treatment modalities in pediatric brain tumors, chemotherapy also has an important part in the management of these tumors. However, most of the available chemotherapeutic drugs have suboptimal effectiveness. Deregulation of various pro-apoptotic and anti-apoptotic pathways has been cited as a major mechanism underlying this drug resistance. The role of various serine threonine kinases, including Akt kinases, in promoting drug resistance is being extensively studied in various cancers. A complete understanding of the molecular mechanisms that underlie drug …

Acceptable Noise Levels In Children Ages 10 To 11 Years And 14 To 15 Years, Krystal Sullivan Ware

Doctoral Dissertations

The present study measured acceptance of background noise in 35 children (age 10–11 and 14–15 years) with normal hearing sensitivity. Acceptance of background noise was measured using the acceptable noise level (ANL) procedure. To obtain an ANL, participants' MCL was first obtained using a running story. Then a competing stimulus (i.e., speech babble or speech spectrum noise) was introduced, and the listeners were asked to adjust the level of the background noise to the most he/she could put up with and follow the story for a long period of time. This level was called background noise level or BNL. The …

Stuck Together: Searching For A Model Of Peritoneal Adhesions Using The August Rat, James W. Bathe Apr 2010

Stuck Together: Searching For A Model Of Peritoneal Adhesions Using The August Rat, James W. Bathe

Honors Theses

Fibrous adhesions, a by-product of the healing process, often appear post-surgically as a result of peritonitis related to the surgery. These adhesions can be either primarily "scar tissue" or excess "healthy tissue," and are the leading cause of intestinal obstruction in modern medicine. Shockingly, adhesions occur in up to 96% of patients undergoing intra-abdominal surgery. Adhesions can lead to multiple complications other than obstructions such as inadvertent enterotomy at the time of adhesiolysis, chronic pain, and female infertility. Additional complications arise from the adhesions preventing the free movement of organs and causing strangulations. The causes of the peritonitis, and therefore …

A Gis Analysis Of The Environmental Variables Related To Rift Valley Fever Outbreaks, Jacqueline Florette Jackson

Health Services Research Dissertations

Rift Valley fever is a mosquito-borne disease that causes widespread febrile illness and mortality in domestic animals as well as humans (Gaff, 2007). Rift Valley fever virus was first isolated in 1931 (Daubney, 1931), and since then, outbreaks have occurred in sub-Saharan Africa, southern Africa, Egypt, Saudi Arabia, Yemen and Madagascar, proving it to be a virus able to invade ecologically diverse regions (Gaff, 2007). The potential introduction of Rift Valley fever into the United States suggests the potential for human infection and major economic disruption. It is important to understand the role environmental variables have played in historical outbreaks …

African American Women's Infant Feeding Choices: Analyzing Self-Efficacy And Narratives From A Black Feminist Perspective, Karen Marie Robinson Apr 2010

African American Women's Infant Feeding Choices: Analyzing Self-Efficacy And Narratives From A Black Feminist Perspective, Karen Marie Robinson

Dissertations (1934 -)

Breast milk is the optimal form of nutrition for infants up to six months of age. Commercial formula is unequal to breast milk nutritionally, economically, and psychologically. African American women (AAW) continue to breastfeed the least compared to other populations. Few researchers conducting research related AAW's infant feeding preferences have employed the Black Feminist philosophy or the theory of self-efficacy. This philosophy and theory may offer insight into factors that influence AAW's infant feeding choices.

The purpose of this mixed-method study was to examine prenatal breastfeeding self-efficacy (confidence) and actively listen to and analyze AAW's reports of factors influencing their …
