Regulation Of Nachrs And Stemness By Nicotine And E-Cigarettes In Nsclc, Courtney Schaal

USF Tampa Graduate Theses and Dissertations

Lung cancer is the leading cause of cancer-related death in both men and women, nationally and internationally and kills more people each year than breast, prostate, and colon cancers combined. Non-small cell lung carcinoma (NSCLC) is the most common histological subtype of lung cancer, and accounts for 85% of all cases. Cigarette smoking is the single greatest risk factor for lung cancer, and is correlated with 80-90% of all lung cancer deaths. Nicotine, the addictive component of tobacco smoke, is not a carcinogen and cannot initiate tumors itself; however, it is known to act as a tumor promoter, by enhancing …


Dementia In Prison: An Argument For Training Correctional Officers, Rachele Vogel Aug 2016

Dementia In Prison: An Argument For Training Correctional Officers, Rachele Vogel

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Dementia is a significant public health problem that is occurring behind bars. However, the number of inmates suffering from this disease is unknown (Feczko, 2014). Current research has exposed a serious gap in correctional health care for older adults, and correctional institutions are being encouraged to make changes to better address the needs of this population (Fellner, 2012; OIG, 2016; Williams, Stern, Mellow, Safer, & Greifinger, 2012b). The purpose of this paper is to bring awareness to the aging problem behind bars and respond to the identified need for additional training for custodial staff (correctional, parole, and probation officers). Training …


A Case Study Using The Biopsychosocial Vulnerability-Stress Model As A Framework To Understand The Incarceration Experience, Annette T. Maruca Aug 2016

A Case Study Using The Biopsychosocial Vulnerability-Stress Model As A Framework To Understand The Incarceration Experience, Annette T. Maruca

Journal for Evidence-based Practice in Correctional Health

In the United States, the Center for Disease Control estimates that about 80% of incarcerated inmates have a substance abuse problem. More than one fourth of inmates are in prisons because of drug related arrests. Additionally, many inmates have cooccurring mental illness disorders as well as health related issues. A multiple (four) case study design was used to explore the association between co-occurring diagnoses, antisocial traits and challenging behaviors within the incarcerated population. The analysis revealed that the four co-occurring diagnoses studied did contribute to poor health outcomes. Study findings suggest that there is a great need to create services …


Biopsychosocial Vulnerability-Stress Modeling For An Incarcerated Population, Deborah Shelton, Bill Barta, Robert Trestman, Sara Wakai Aug 2016

Biopsychosocial Vulnerability-Stress Modeling For An Incarcerated Population, Deborah Shelton, Bill Barta, Robert Trestman, Sara Wakai

Journal for Evidence-based Practice in Correctional Health

This paper discusses individual constructs that form diathesis-stress models and formulates an adapted model for a corrections population. Diathesis-stress models are familiar within psychiatric nursing, but rarely discussed in the literature in their application to correctional population, or for their potential in guiding nursing practice in correctional settings. Of particular interest to this paper is the coping response of inmates to the stressors of incarceration and the implications for clinical care management.

Role Of Spinophilin In Group I Metabotropic Glutamate Receptor Endocytosis, Signaling, And Synaptic Plasticity, Andrea R. Di Sebastiano, Sandra Fahim, Henry A. Dunn, Cornelia Walther, Fabiola M. Ribeiro, Sean P. Cregan, Stephane Angers, Susanne Schmid, Stephen S. G. Ferguson

Anatomy and Cell Biology Publications

Activation of Group I metabotropic glutamate receptors (mGluRs) activates signaling cascades, resulting in calcium release from intracellular stores, ERK1/2 activation, and long term changes in synaptic activity that are implicated in learning, memory, and neurodegenerative diseases. As such, elucidating the molecular mechanisms underlying Group I mGluR signaling is important for understanding physiological responses initiated by the activation of these receptors. In the current study, we identify the multifunctional scaffolding protein spinophilin as a novel Group I mGluR-interacting protein. We demonstrate that spinophilin interacts with the C-terminal tail and second intracellular loop of Group I mGluRs. Furthermore, we show that interaction …


The Role Of Inflammatory Monocytes In Post-Influenza Methicillin-Resistant Staphylococcus Aureus Pneumonia, Karl J. Fischer Aug 2016

The Role Of Inflammatory Monocytes In Post-Influenza Methicillin-Resistant Staphylococcus Aureus Pneumonia, Karl J. Fischer

Theses & Dissertations

Secondary bacterial infections following influenza can lead to poor clinical outcomes and mortality. It is widely accepted that susceptibility to secondary bacterial infections is attributable to a suppressed innate antibacterial immunity. In contrast, a dysregulated host inflammatory response may also contribute to disease severity. Inflammation induced by viral infection alone significantly affects lung pathology, potentially exacerbating the destruction of the respiratory tract. Interestingly, the role of inflammatory mediators such as inflammatory monocytes have been extensively studied during influenza infection alone; however, their role during secondary bacterial infection are still not fully established. The objective of this study was to analyze …


The Pathogenesis Of Natural Killer/T Cell Lymphoma, Bei Jiang Aug 2016

The Pathogenesis Of Natural Killer/T Cell Lymphoma, Bei Jiang

Theses & Dissertations

Extranodal natural killer/T-cell lymphomas (NKTCL) are uncommon lymphomas with poor prognosis. In order to gain a better understanding of the molecular pathogenesis of NKTCL, we obtained and compared the global gene expression profile, global somatic mutation profile, and global methylation profile of normal NK cells, malignant NK cell lines, and NKTCL patient samples. We showed that the JAK-STAT pathway was constitutively activated in NKTCL through the cooperation between activation of signal transducer and activator of transcription proteins (STATs) via activating mutations and inactivation of STAT suppressor protein suppressor of cytokine signaling 6 (SOCS6) through promoter hypermethylation. Activating STAT3 and STAT5B …


Assessing Change In Baseline Preparedness Knowledge In Long-Term Care Facilities, Heidi L. Wheeler Aug 2016

Assessing Change In Baseline Preparedness Knowledge In Long-Term Care Facilities, Heidi L. Wheeler

Theses & Dissertations

With much of the focus and federal resources in recent history going to support hospital preparedness, long-term care facilities have been left behind even though they house one of our most vulnerable populations. Few regulations and standards have required these facilities to keep pace with preparing for an increasingly volatile environment and aging society. This is changing with the proposal of new federal standards and regulations requiring more thorough and robust preparedness planning. These new requirements do not have to be overwhelming or burdensome to facilities but can be included quite simply into routine planning and training. This study looks …

Long-Acting Antiretroviral Nanoformulation Development And Subcellular Trafficking, Dongwei Guo Aug 2016

Long-Acting Antiretroviral Nanoformulation Development And Subcellular Trafficking, Dongwei Guo

Theses & Dissertations

The introduction of nanoformulated antiretroviral therapeutic regimens is a promising alternative to standard once a day oral treatment of HIV infection. Our lab has pioneered this effort and was successful in harnessing mononuclear phagocytes (monocytes, dendritic cells and macrophages) as nanoformulated drug carriers. The approach was developed as Trojan horses for drug transport, delivery and distribution to sites of viral replication in order to facilitate microbial elimination in HIV sanctuaries. However, the remaining challenges for current antiretroviral nanoformulations include to formulate a broad range of hydrophilic short-acting drugs, and to elucidate the mechanism of sequestered nanoparticles in macrophages at the …

Antioxidant And Anti-Inflammatory Nutrients On Lung Function In Chronic Obstructive Pulmonary Disease, Jessica M. Hinds

Theses & Dissertations

Introduction Veterans are three times more likely to develop chronic obstructive pulmonary disease (COPD) than the general population. This is likely due to increased use of tobacco and exposure to environmental risk factors. Nutritional intake has been linked to COPD, and veterans report unique barriers to improving their eating habits.

Purpose The primary outcome of this study was to examine the relationship between antioxidant and anti-inflammatory nutrient intake and lung function in veterans with COPD. It was hypothesized that a higher intake of lutein + zeaxanthin, ß-cryptoxanthin, lycopene, retinol, ɑ-carotene, ß-carotene, vitamin C, vitamin D, ɑ-tocopherol, omega-3, zinc and selenium …


Changes To Echocardiography-Derived Left Ventricular Filling Pressures And Cardiac Output In Response To Fluid Boluses In Elderly Patients With Left Ventricular Diastolic Dysfunction Undergoing Vascular Surgery, Sasha K. Shillcutt Aug 2016

Changes To Echocardiography-Derived Left Ventricular Filling Pressures And Cardiac Output In Response To Fluid Boluses In Elderly Patients With Left Ventricular Diastolic Dysfunction Undergoing Vascular Surgery, Sasha K. Shillcutt

Theses & Dissertations

Left ventricular diastolic dysfunction (LVDD) of the heart is a condition where the heart does not relax properly. This condition is important during times of stress, as LVDD is associated with significant morbidity of elderly surgical patients. LVDD is often asymptomatic and unrecognized as many of these patients have normal ejection fractions. However, LVDD may lead to heart failure in patients with preserved systolic function, with the incidence being as high as 50% in hospitalized elderly patients. The diagnosis of LVDD is an independent risk factor for postoperative major adverse cardiac events (MACE) and negatively impacts post-surgery readmission rates. Anesthesiologists …

Stability And Kinetics Of Dna Pseudoknots: Formation Of T∗A•T Base-Triplets And Their Targeting Reactions, Calliste Steffensmeier

Theses & Dissertations

Pseudoknots have been found to play important roles in the biology of RNA. These stem-loop motifs are considered to be very compact and the targeting of their loops with complementary strands is accompanied with lower favorable free energy terms. We used a combination of spectroscopic (UV, CD and fluorescence), calorimetric (DSC, PPC and ITC) and kinetic (SPR) techniques to investigate: 1) Local base-triplet formation in pseudoknots; 2) energetic contributions for the association of pseudoknots with their complementary strands; and 3) the kinetic rates as a function of targeting strand length.

We investigated a set of DNA pseudoknots with sequence: d(TCTCT …
