Necrostatin-1 (Nec-1) is widely used in disease models to examine the contribution of receptor-interacting protein kinase (RIPK) 1 in cell death and inflammation. We studied three Nec-1 analogs: Nec-1, the active inhibitor of RIPK1, Nec-1 inactive (Nec-1i), its inactive variant, and Nec-1 stable (Nec-1s), its more stable variant. We report that Nec-1 is identical to methyl-thiohydantoin-tryptophan, an inhibitor of the potent immunomodulatory enzyme indoleamine 2,3-dioxygenase (IDO). Both Nec-1 and Nec-1i inhibited human IDO, but Nec-1s did not, as predicted by molecular modeling. Therefore, Nec-1s is a more specific RIPK1 inhibitor lacking the IDO-targeting effect. Next, although Nec-1i was ∼100 × …

The development of new small molecule-based therapeutic drugs requires accurate quantification of drug bioavailability, biological activity and treatment efficacy. Rapidly measuring these endpoints is often hampered by the lack of efficient assay platforms with high sensitivity and specificity. Using an in vivo model system, we report a simple and sensitive liquid chromatography-tandem mass spectrometry assay to quantify the bioavailability of a recently developed novel cyclin-dependent kinase inhibitor VMY-1-103, a purvalanol B-based analog whose biological activity is enhanced via dansylation. We developed a rapid organic phase extraction technique and validated wide and functional VMY-1-103 distribution in various mouse tissues, consistent with …

Biosynthetic Pathways And The Role Of The Mas Receptor In The Effects Of Angiotensin-(1-7) In Smooth Muscles., Marcio Augusto Fressatto De Godoy, Larissa Pernomian, Ana Maria De Oliveira, Satish Rattan

Department of Medicine Faculty Papers

Ang-(1-7) is produced via degradation of Ang II by the human angiotensin converting enzyme, also known as ACE2. In the cardiovascular system, Ang-(1-7) has been shown to produce effects that are opposite to those of Ang II. These include smooth muscle relaxation and cardioprotection. While the roles of Ang-(1-7) in other systems are currently topic of intense research, functional data suggest a relaxation action in gastrointestinal smooth muscles in a way that corroborates the results obtained from vascular tissues. However, more studies are necessary to determine a relevant role for Ang-(1-7) in the gastrointestinal system. The Ang-(1-7) actions are mediated …

Common Roots: A Contextual Review Of Hiv Epidemics In Black Men Who Have Sex With Men Across The African Diaspora, Gregorio A. Millett, William L. Jeffries 4h, John L. Peterson, David J. Malebranche, Tim Lane, Stephen A. Flores, Kevin A. Fenton, Patrick A. Wilson, Riley Steiner, Charles M. Heilig

David J Malebranche

Pooled estimates from across the African diaspora show that black men who have sex with men (MSM) are 15 times more likely to be HIV positive compared with general populations and 8·5 times more likely compared with black populations. Disparities in the prevalence of HIV infection are greater in African and Caribbean countries that criminalise homosexual activity than in those that do not criminalise such behaviour. With the exception of US and African epidemiological studies, most studies of black MSM mainly focus on outcomes associated with HIV behavioural risk rather than on prevalence, incidence, or undiagnosed infection. Nevertheless, black MSM …

Daily Experiences Of Older Adults With Mild Cognitive Impairment, Elizabeth Hahn

USF Tampa Graduate Theses and Dissertations

Rationale and study aims: Persons with mild cognitive impairment (MCI) experience declines in everyday functioning and cognitive performance greater than what is experienced in normal aging but less than that of dementia. Daily stress and daily memory complaints associated with cognitive deficits may contribute to greater psychological distress in the day-to-day experiences of persons with MCI. However, research examining the occurrence of daily stressors, daily memory complaints and psychological distress in MCI is limited, and it is not clear how the daily processes of stress and affect in persons with MCI compare to cognitively healthy older adults. This dissertation examined …

Road Map To Becoming A Physician Assistant, Maguire J. Miller

Senior Honors Projects

The field of medicine is under constant change and reconstruction, especially when it comes to healthcare practitioners. When a demand is placed on the system, healthcare providers must figure out how they can satisfy the medical needs of the population. Within the past few decades there has been a shortage of people who are capable of fulfilling these needs. For this reason a new profession has been developed; it is called a Physician Assistant (PA). Professionals with this title have been through a rigorous training modeled after what a medical student goes through, but it is condensed into a much …

Mitochondrial Lysyl-Trna Synthetase Independent Import Of Trna Lysine Into Yeast Mitochondria., Naresh Babu V Sepuri, Madhavi Gorla, Michael P King

Department of Biochemistry and Molecular Biology Faculty Papers

Aminoacyl tRNA synthetases play a central role in protein synthesis by charging tRNAs with amino acids. Yeast mitochondrial lysyl tRNA synthetase (Msk1), in addition to the aminoacylation of mitochondrial tRNA, also functions as a chaperone to facilitate the import of cytosolic lysyl tRNA. In this report, we show that human mitochondrial Kars (lysyl tRNA synthetase) can complement the growth defect associated with the loss of yeast Msk1 and can additionally facilitate the in vitro import of tRNA into mitochondria. Surprisingly, the import of lysyl tRNA can occur independent of Msk1 in vivo. This suggests that an alternative mechanism is present …

Dyschronic, A Drosophila Homolog Of A Deaf-Blindness Gene, Regulates Circadian Output And Slowpoke Channels., James E C Jepson, Mohammad Shahidullah, Angelique Lamaze, Drew Peterson, Huihui Pan, Kyunghee Koh

Farber Institute for Neuroscience Faculty Papers

Many aspects of behavior and physiology are under circadian control. In Drosophila, the molecular clock that regulates rhythmic patterns of behavior has been extensively characterized. In contrast, genetic loci involved in linking the clock to alterations in motor activity have remained elusive. In a forward-genetic screen, we uncovered a new component of the circadian output pathway, which we have termed dyschronic (dysc). dysc mutants exhibit arrhythmic locomotor behavior, yet their eclosion rhythms are normal and clock protein cycling remains intact. Intriguingly, dysc is the closest Drosophila homolog of whirlin, a gene linked to type II Usher syndrome, the leading cause …

Sex and gender differences influence the health and wellbeing of men and women. Although studies have drawn attention to observed differences between women and men across diseases, remarkably little research has been pursued to systematically investigate these underlying sex differences. Women continue to be underrepresented in clinical trials, and even in studies in which both men and women participate, systematic analysis of data to identify potential sex-based differences is lacking. Standards for reporting of clinical trials have been established to ensure provision of complete, transparent and critical information. An important step in addressing the gender imbalance would be inclusion of …

Loss Of Αt-Catenin Alters The Hybrid Adhering Junctions In The Heart And Leads To Dilated Cardiomyopathy And Ventricular Arrhythmia Following Acute Ischemia., Jifen Li, Steven Goossens, Jolanda Van Hengel, Erhe Gao, Lan Cheng, Koen Tyberghein, Xiying Shang, Riet De Rycke, Frans Van Roy, Glenn L Radice

Center for Translational Medicine Faculty Papers

It is generally accepted that the intercalated disc (ICD) required for mechano-electrical coupling in the heart consists of three distinct junctional complexes: adherens junctions, desmosomes and gap junctions. However, recent morphological and molecular data indicate a mixing of adherens junctional and desmosomal components, resulting in a 'hybrid adhering junction' or 'area composita'. The α-catenin family member αT-catenin, part of the N-cadherin-catenin adhesion complex in the heart, is the only α-catenin that interacts with the desmosomal protein plakophilin-2 (PKP2). Thus, it has been postulated that αT-catenin might serve as a molecular integrator of the two adhesion complexes in the area composita. …

The Influence Of Antiretroviral Therapy On The Qtc Interval In An African Cohort, J. Shavadia, Reena Shah, Gerald Yonga, R. Patel, J. Stebbing, M. Nelson

Internal Medicine, East Africa

Cardiovascular disease in human immunodeficiency virus (HIV) infection encompasses a wide range of pathologic entities, including myocardial, pericardial, and endocardial disease, atherosclerosis, arrhythmias, and vasculitis. The most common manifestations of HIV-associated heart disease in sub- Saharan Africa are pericarditis, cardiomyopathy, and pulmonary hypertension [1]. Coronary artery disease, lipodystrophy, and metabolic syndrome, although common in developed countries, are traditionally thought to be less clinically significant problems in the African subcontinent [2]. It is well known that prolongation of the QTC interval can predispose patients to potentially fatal ventricular tachyarrhythmias, particularly torsades de pointes, and thus is an independent predictor of cardiovascular …

Patients' And Caregivers' Inside Perspectives: Living With A Left-Ventricular Assist Device As Destination Therapy, Linda Marcuccilli

Wayne State University Dissertations

Left-ventricular assist devices (LVADs) have improved the quality of life for many patients with advanced heart failure. Past research focused on technology issues and survival rates, but patients' and caregivers' perspectives of living with an LVAD as a destination therapy (e.g., permanent alternative to transplant) was not explored. Roy's adaptation model provided a framework to guide an understanding of how participants adjusted and accepted living with destination therapy. A hermeneutic-phenomenology as described by van Manen was used to explore and describe the essence of destination therapy from patients' and caregivers' perspectives in order to understand the meaning of this experience. …

Type 2 Diabetes And Insomnia: Impact On Metabolic Control, Cheryl Lee Tannas

Wayne State University Dissertations

Diabetes is one of the most serious health challenges in the United States, affecting nearly 21 million Americans. The goal of diabetes management is to maintain the blood glucose close to normal to prevent diabetic complications and therefore extending life expectancy and improving quality of life. Research now indicates a relationship of the quantity and quality of sleep to glycemic control in type 2 diabetics. No research on the impact of insomnia on diabetes prevention and/or management was found in the literature. The purpose of this 11 week intervention study was to examine the effects of participation in Cognitive Behavioral …

Measurement And Correlates Of Empathy Among Female Japanese Physicians., Hitomi U Kataoka, Norio Koide, Mohammadreza Hojat, Joseph S Gonnella

CRMEHC Faculty Papers

BACKGROUND: The measurement of empathy is important in the assessment of physician competence and patient outcomes. The prevailing view is that female physicians have higher empathy scores compared with male physicians. In Japan, the number of female physicians has increased rapidly in the past ten years. In this study, we focused on female Japanese physicians and addressed factors that were associated with their empathic engagement in patient care.

METHODS: The Jefferson Scale of Empathy (JSE) was translated into Japanese by using the back-translation procedure, and was administered to 285 female Japanese physicians. We designed this study to examine the psychometrics …

Bereavement Outcomes Among Spousal Hospice Caregivers: The Role Of Rumination, Feelings Of Relief, And Perceived Suffering, Jessica Y. Allen

USF Tampa Graduate Theses and Dissertations

Background: The death of a spouse is among the most distressing life events faced by older adults and frequently follows long periods of providing extensive care and support. Although many spouses are resilient following loss, a number of bereaved spousal caregivers have poor psychological well-being and may benefit from clinical services. However, it can be difficult to determine who may most benefit from bereavement services and why some individuals are at greater risk for poor bereavement; thus, there is a need for greater understanding of the process of bereavement. Therefore, the purpose of this dissertation was to investigate a number …

Genes Adopt Non-Optimal Codon Usage To Generate Cell Cycle-Dependent Oscillations In Protein Levels., Milana Frenkel-Morgenstern, Tamar Danon, Thomas Christian, Takao Igarashi, Lydia Cohen, Ya-Ming Hou, Lars Juhl Jensen

Department of Biochemistry and Molecular Biology Faculty Papers

The cell cycle is a temporal program that regulates DNA synthesis and cell division. When we compared the codon usage of cell cycle-regulated genes with that of other genes, we discovered that there is a significant preference for non-optimal codons. Moreover, genes encoding proteins that cycle at the protein level exhibit non-optimal codon preferences. Remarkably, cell cycle-regulated genes expressed in different phases display different codon preferences. Here, we show empirically that transfer RNA (tRNA) expression is indeed highest in the G2 phase of the cell cycle, consistent with the non-optimal codon usage of genes expressed at this time, and lowest …
