Co-Morbidities Associated With Adult Obesity In Mississippi, Richmond Lachney

MSN Research Projects

Obesity rates are rapidly increasing in Mississippi and the entire United States. It is estimated that 34.9% of Mississippi residents and 75 million Americans over the age of 20 are considered obese. Numerous studies have shown the high risk of developing co­ morbidities once a person develops obesity. The number of adult Americans living with obesity and its associated co-morbidities is alarming. The purpose of this study was to determine which co-morbidities are most prevalent among obese residents of rural Mississippi and whether they can be reduced or reversed with significant weight reduction. Nola Pender’s Health Promotion Model was utilized …

Amyloid Β Peptides Modify The Expression Of Antioxidant Repair Enzymes And A Potassium Channel In The Septohippocampal System, Jorge Duran-Gonzalez, Edna D. Michi, Brisa Elorza, Miriam G. Perez-Cordova, Luis F. Pacheco Otalora, Ahmed Touhami, Pamela Paulson, George Perry, Ian V. Murray, Luis V. Colom

Health & Biomedical Sciences Faculty Publications

Alzheimer's disease (AD) is a progressive, neurodegenerative brain disorder characterized by extracellular accumulations of amyloid β (Aβ) peptides, intracellular accumulation of abnormal proteins, and early loss of basal forebrain neurons. Recent studies have indicated that the conformation of Aβ is crucial for neuronal toxicity, with intermediate misfolded forms such as oligomers being more toxic than the final fibrillar forms. Our previous work shows that Aβ blocks the potassium (K(+)) currents IM and IA in septal neurons, increasing firing rates, diminishing rhythmicity and firing coherence. Evidence also suggests that oxidative stress (OS) plays a role in AD pathogenesis. Thus we wished …

Hippocampal Functional Connectivity Patterns During Spatial Working Memory Differ In Right Versus Left Temporal Lobe Epilepsy., Gaelle Eve Doucet, Karol Osipowicz, Ashwini Sharan Md, Michael R Sperling, Joseph I Tracy

Department of Neurology Faculty Papers

Temporal lobe epilepsy (TLE), affecting the medial temporal lobe, is a disorder that affects not just episodic memory but also working memory (WM). However, the exact nature of hippocampal-related network activity in visuospatial WM remains unclear. To clarify this, we utilized a functional connectivity (FC) methodology to investigate hippocampal network involvement during the encoding phase of a functional magnetic resonance imaging (fMRI) visuospatial WM task in right and left TLE patients. Specifically, we assessed the relation between FC within right and left hippocampus-seeded networks, and patient performance (rate of correct responses) during the encoding phase of a block span WM …

System Design And Motion Artifact Removal Algorithm Implementation For Ambulatory Women Ecg Measurement System:E-Bra System, Hyeokjun Kwon

Graduate Theses and Dissertations

Cardio Vascular Disease (CVD) leads to sudden cardiac death due to irregular phenomenon of the cardiac signal by the abnormal case of blood vessel and cardiac structure. For last three decades, there is an enhanced interest in research for cardiac diseases.. As a result, the death rate by cardiac disease in men has been falling gradually compared with relatively increasing the death rate for women due to CVD. The main reason for this phenomenon is due to the lack of seriousness to female CVD and different symptoms of female CVD compared with the symptoms of male CVD. Usually, because the …

Rupture Test And Bioavailability Of Oil-Soluble Vitamins, Lipika Chablani

Pharmacy Faculty/Staff Publications

In lieu of an abstract, here is the article's first paragraph:

Bioavailability of multi-vitamins as dietary supplements has always been a concern. Dissolution studies have been successfully used to predict drug release of bioactive molecules, but with vitamins there are some exceptions. United State Pharmacopoeia (USP) defines the dissolution requirements of multi-vitamin supplements based on the composition and type of dosage form. As oil-soluble vitamins do not meet the criterion of “dissolution”, the performance of dosage forms containing such vitamins is evaluated by disintegration studies primarily. Dissolution studies are not applicable for such dosage forms [1].

Profile Of Vismodegib And Its Potential In The Treatment Of Advanced Basal Cell Carcinoma., Muzafar A. Macha, Surinder K. Batra, Apar Kishor Ganti

Journal Articles: Biochemistry & Molecular Biology

Basal cell carcinoma (BCC) is the most common human malignancy. Recent advances in our understanding of the critical biologic pathways implicated in the development and progression of BCC have led to the development of the first molecular targeted therapy for this disease. The hedgehog pathway is mutated in virtually all patients with BCC and recent trials with vismodegib, an inhibitor of this pathway, have shown significant responses. This review will discuss the importance of the hedgehog pathway in the pathogenesis of BCC and describe in detail the pharmacology of vismodegib in relation to its activity in advanced BCC.

Standardized forms were used to collect data on body mass index (BMI), waist circumference (WC), cardiovascular risk factors, and medications. Peak troponin I and creatinine phosphokinase (CPK) were used to estimate infarct size. Epicardial and pericardial fat were measured by echocardiography. We used univariate …

Online Healthy Lifestyle Support In The Perinatal Period: What Do Women Want And Do They Use It?, Lydia A. Hearn, Margaret R. Miller, Anna Fletcher

Research outputs 2013

Unhealthy weight gain and retention during pregnancy and postpartum is detrimental to mother and child. Although various barriers limit the capacity for perinatal health care providers (PHCPs) to offer healthy lifestyle counselling, they could guide women to appropriate online resources. This paper presents a project designed to provide online information to promote healthy lifestyles in the perinatal period. Focus groups or interviews were held with 116 perinatal women and 76 PHCPs to determine what online information perinatal women and PHCPs want, in what form, and how best it should be presented. The results indicated that women wanted smartphone applications (apps) …

Is Health Diplomacy Keeping Pace With Global Health Developments? Implications For Access To Medicines Strategies In The Post-2015 Mdg Framework, Samantha Ski, Rachel Kiddell-Monroe, James M. Sherry

Global Health Faculty Publications

As the 2015 deadline to achieve the Millennium Development Goals (MDGs) draws near, efforts to ensure access to essential medicines face new challenges in light of new resource constraints. To help assess those challenges, a summary analysis of published data was undertaken to examine the increasing discontinuity between the geographic focus of donor-country programs on low-income countries (LICs) and the geographic location of the increasing majority of the poor and the global burden of preventable disease within middle-income countries (MICs). This disconnect has put new pressure on both donor and government resources for essential medicines, prompting greater consideration of strategies …

Combination Of Sirna-Directed Gene Silencing With Cisplatin Reverses Drug Resistance In Human Non-Small Cell Lung Cancer, Shanthi Ganesh, Arun K. Iyer, Jan Weller, David V. Morrissey, Mansoor M. Amiji

Pharmaceutical Sciences Faculty Publications

One of the most challenging aspects of lung cancer therapy is the rapid acquisition of multidrug-resistant (MDR) phenotype. One effective approach would be to identify and downregulate resistance-causing genes in tumors using small interfering RNAs (siRNAs) to increase the sensitivity of tumor cells to chemotherapeutic challenge. After identifying the overexpressed resistance-related antiapoptotic genes (survivin and bcl-2) in cisplatin-resistant cells, the siRNA sequences were designed and screened to select the most efficacious candidates. Modifications were introduced in them to minimize off-target effects. Subsequently, the combination of siRNA and cisplatin that gave the maximum synergy was identified in resistant cells. We then …

A Novel Biorelevant In Vitro System To Predict The In Vivo Performance Of Oral Transmucosal Products, Poonam Delvadia

Theses and Dissertations

In vitro dissolution, release and permeation testing is a common practice during drug product research and development. These in vitro tests, if predictive, are referred to as biorelevant tests and can play diverse roles to facilitate and expedite product development in a cost effective manner. Oral transmucosal products (OTPs) are currently tested using compendial and modified in vitro tests which may or may not be good predictors of in vivo performance due to a lack of biorelevance. A critical need for a broadly applicable and biorelevant in vitro system for OTPs has been expressed in the literature and the goal …

Ron Knockdown And Ron Monoclonal Antibody Imc-Ron8 Sensitize Pancreatic Cancer To Histone Deacetylase Inhibitors (Hdaci)., Yi Zou, Gillian M. Howell, Lisa E. Humphrey, J. Wang, Michael G. Brattain

Journal Articles: Eppley Institute

Recepteur d'origine nantais (Ron) is overexpressed in a panel of pancreatic cancer cells and tissue samples from pancreatic cancer patients. Ron can be activated by its ligand macrophage stimulating protein (MSP), thereby activating oncogenic signaling pathways. Crosstalk between Ron and EGFR, c-Met, or IGF-1R may provide a mechanism underlying drug resistance. Thus, targeting Ron may represent a novel therapeutic strategy. IMC-RON8 is the first Ron monoclonal antibody (mAb) entering clinical trial for targeting Ron overexpression. Our studies show IMC-RON8 downmodulated Ron expression in pancreatic cancer cells and significantly blocked MSP-stimulated Ron activation, downstream Akt and ERK phosphorylation, and survivin mRNA …

Direction Of Aminoacylated Transfer Rnas Into Antibiotic Synthesis And Peptidoglycan-Mediated Antibiotic Resistance, Jennifer Shepherd, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Prokaryotic aminoacylated‐transfer RNAs often need to be efficiently segregated between translation and other cellular biosynthetic pathways. Many clinically relevant bacteria, including Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus faecalis and Pseudomonas aeruginosa direct some aminoacylated‐tRNA species into peptidoglycan biosynthesis and/or membrane phospholipid modification. Subsequent indirect peptidoglycan cross‐linkage or change in membrane permeability is often a prerequisite for high‐level antibiotic resistance. In Streptomycetes, aminoacylated‐tRNA species are used for antibiotic synthesis as well as antibiotic resistance. The direction of coding aminoacylated‐tRNA molecules away from translation and into antibiotic resistance and synthesis pathways are discussed in this review.

Pediatric Palliative Care For Youth With Hiv/Aids: Systematic Review Of The Literature, Megan L. Wilkins, Ronald H. Dallas, Kathleen E. Fanone, Maureen E. Lyon

Pediatrics Faculty Publications

Improvement in treatment has led to decreased death in youth with human immunodeficiency virus (HIV) in developed countries. Despite this, youth with HIV are still at risk for increased mortality and morbidity compared with their uninfected counterparts. In developing countries, high numbers of youth die from acquired immune deficiency syndrome (AIDS)-related illnesses due to lack of access to consistent antiretroviral treatment. As a result, pediatric palliative care is a relevant topic for those providing care to youth with HIV. A systematic review was conducted to gather information regarding the status of the literature related to pediatric palliative care and medical …

Analysis Of Unannotated Equine Transcripts Identified By Mrna Sequencing, Stephen J. Coleman, Zheng Zeng, Matthew S. Hestand, Jinze Liu, James N. Macleod

Veterinary Science Faculty Publications

Sequencing of equine mRNA (RNA-seq) identified 428 putative transcripts which do not map to any previously annotated or predicted horse genes. Most of these encode the equine homologs of known protein-coding genes described in other species, yet the potential exists to identify novel and perhaps equine-specific gene structures. A set of 36 transcripts were prioritized for further study by filtering for levels of expression (depth of RNA-seq read coverage), distance from annotated features in the equine genome, the number of putative exons, and patterns of gene expression between tissues. From these, four were selected for further investigation based on predicted …

Prefrontal Cortical Microcircuits Bind Perception To Executive Control, Ioan Opris, Lucas Santos, Greg A. Gerhardt, Dong Song, Theodore W. Berger, Robert E. Hampson, Sam A. Deadwyler

Neuroscience Faculty Publications

During the perception-to-action cycle, our cerebral cortex mediates the interactions between the environment and the perceptual-executive systems of the brain. At the top of the executive hierarchy, prefrontal cortical microcircuits are assumed to bind perceptual and executive control information to guide goal-driven behavior. Here, we tested this hypothesis by comparing simultaneously recorded neuron firing in prefrontal cortical layers and the caudate-putamen of rhesus monkeys, trained in a spatial-versus-object, rule-based match-to-sample task. We found that during the perception and executive selection phases, cell firing in the localized prefrontal layers and caudate-putamen region exhibited similar location preferences on spatial-trials, but less on …

Anti-Cytomegalovirus Activity Of Atanyl Blue Prl, An Anthraquinone Derivative, Zohaib Alam

Theses and Dissertations

Cytomegalovirus (CMV) is a significant cause of mortality and morbidity in immunocompromised patients and an important cause of birth defects if acquired in utero. The licensed CMV antivirals, ganciclovir, cidofovir and foscarnet, all target the viral DNA polymerase. For each drug prolonged use is associated with significant toxicities and development of drug resistance. None are approved for use during pregnancy. Therefore, development of new anti-CMV drugs that target different pathways would be beneficial. All herpesviruses encode an alkaline nuclease. That genetic disruption of the CMV alkaline nuclease, UL98, reduces CMV replication by 1,000-fold suggests that UL98 may be a useful …
