Role Of Porcine Reproductive And Respiratory Syndrome Virus Non-Structural Protein 1 In Viral Replications And Pathogenesis, Lalit Kumar Beura

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Porcine reproductive and respiratory syndrome virus (PRRSV) is an infectious agent of significant concern to the global swine industry. PRRSV infection of pigs is initiated by a long viremia after which the virus enters in an extended persistent phase of 3-4 months that ultimately is resolved by the immune system. The delayed and weak host adaptive response is responsible for the protracted convalescence period. An initial sub-optimal innate immune response is postulated to be the reason behind such meager adaptive immune response. A major focus of the studies undertaken in this dissertation was to identify the viral non-structural proteins (nsps) …

Identification Of Host Proteins Required For Vesicular Stomatitis Virus Infection, Debasis Panda

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Viruses usurp host cell pathways for different stages of their infection. Understanding virus-host interaction will be invaluable to elucidate molecular mechanisms of virus infection and to identify drug targets. In order to identify such critical cellular genes in vesicular stomatitis virus (VSV, a model non-segmented negative strand RNA virus) infection, we developed a stable cell line constitutively expressing replication proteins of VSV. Attempts to establish a cell line replicating a sub-genomic replicon was not successful because of induction of interferon response by replication of viral genomic analog. Subsequently, we used siRNA technology and conducted a genome-wide siRNA screen in HeLa …

Upregulation Of Reactive Oxygen Species During The Retrovirus Life Cycle And Their Roles In A Mutant Of Moloney Murine Leukemia Virus, Ts1-Mediated Neurodegeneration, Soo Jin Kim

Dissertations and Theses (Open Access)

Viral invasion of the central nervous system (CNS) and development of neurological symptoms is a characteristic of many retroviruses. The mechanism by which retrovirus infection causes neurological dysfunction has yet to be fully elucidated. Given the complexity of the retrovirus-mediated neuropathogenesis, studies using small animal models are extremely valuable. Our laboratory has used a mutant moloney murine leukemia retrovirus, ts1-mediated neurodegneration. We hypothesize that astrocytes play an important role in ts1-induced neurodegeneration since they are retroviral reservoirs and supporting cells for neurons. It has been shown that ts1 is able to infect astrocytes in vivo and in …

Hiv-1 Matrix Protein Binding To Rna, Ayna Alfadhli, Henry Mcnett, Seyram Tsagli, Hans Peter Bachinger, David H. Peyton

Chemistry Faculty Publications and Presentations

The matrix (MA) domain of the HIV-1 precursor Gag (PrGag) protein plays multiple roles in the viral replication cycle. One essential role is to target PrGag proteins to their lipid raft-associated phosphatidylinositol-(4,5)-bisphosphate (PI[4,5]P2) assembly sites at the plasma membranes (PMs) of infected cells. In addition to this role, several reports have implicated nucleic acid binding properties to retroviral MAs. Evidence indicates that RNA binding enhances the binding specificity of MA to PI(4,5)P2-containing membranes, and supports a hypothesis in which RNA binding to MA acts as a chaperone that protects MA from associating with inappropriate cellular membranes prior to PrGag delivery …

Who’S Pandemic Influenza Preparedness Framework: A Milestone In Global Governance For Health, Lawrence O. Gostin, David P. Fidler

Georgetown Law Faculty Publications and Other Works

In May 2008, the World Health Organization (WHO) adopted the Pandemic Influenza Preparedness Framework for the Sharing of Influenza Viruses and Access to Vaccines and Other Benefits (PIP Framework). The PIP Framework’s adoption ended years of difficult negotiations, which began after Indonesia refused to share samples of avian influenza A (H5N1) with WHO in late 2006. Indonesia justified its actions on the need to create more equitable access for developing countries to benefits, such as vaccines and antivirals, derived from research and development on shared influenza virus samples. The global health community feared that failure to share influenza virus samples …

Real-World Comparison Of Two Molecular Methods For Detection Of Respiratory Viruses, Syed Asad Ali, James E. Gern, Tina V. Hartert, Kathryn M. Edwards, Marie R. Griffin, E Kathryn Mille, Tebeb Gebretsadik, Tressa Pappas, Wai Ming Lee, John V. Williams

Department of Paediatrics and Child Health

Background: Molecular polymerase chain reaction (PCR) based assays are increasingly used to diagnose viral respiratory infections and conduct epidemiology studies. Molecular assays have generally been evaluated by comparing them to conventional direct fluorescent antibody (DFA) or viral culture techniques, with few published direct comparisons between molecular methods or between institutions. We sought to perform a real-world comparison of two molecular respiratory viral diagnostic methods between two experienced respiratory virus research laboratories.
Methods: We tested nasal and throat swab specimens obtained from 225 infants with respiratory illness for 11 common respiratory viruses using both a multiplex assay (Respiratory MultiCode-PLx Assay [RMA]) …

Hivtoolbox, An Integrated Web Application For Investigating Hiv, David P. Sargeant, Sandeep Deverasetty, Yang Luo, Angel Villahoz Baleta, Stephanie Zobrist, Viraj Rathnayake, Jacqueline C. Russo, Jay Vyas, Mark A. Muesing, Martin Schiller

Life Sciences Faculty Research

Many bioinformatic databases and applications focus on a limited domain of knowledge federating links to information in other databases. This segregated data structure likely limits our ability to investigate and understand complex biological systems. To facilitate research, therefore, we have built HIVToolbox, which integrates much of the knowledge about HIV proteins and allows virologists and structural biologists to access sequence, structure, and functional relationships in an intuitive web application. HIV-1 integrase protein was used as a case study to show the utility of this application. We show how data integration facilitates identification of new questions and hypotheses much more rapid …

Influenza And Bacterial Coinfections In The 20th Century, Xuan-Yi Wang, Paul E. Kilgore, Kyung Ah Lim, Song-Mei Wang, Jeongseok Lee, Wei Deng, Mei-Qi Mo, Batmunkh Nyambat, Jing-Chen Ma, Michael O. Favorov, John D. Clemens

Department of Pharmacy Practice

To help understand the potential impact of bacterial coinfection during pandemic influenza periods, we undertook a far-reaching review of the existing literature to gain insights into the interaction of influenza and bacterial pathogens. Reports published between 1950 and 2006 were identified from scientific citation databases using standardized search terms. Study outcomes related to coinfection were subjected to a pooled analysis. Coinfection with influenza and bacterial pathogens occurred more frequently in pandemic compared with seasonal influenza periods. The most common bacterial coinfections with influenza virus were due to S. pneumoniae, H. influenzae, Staphylococcus spp., and Streptococcus spp. …

High-Risk Human Papillomavirus (Hpv): An Emerging Health Issue For Women And Minorities, Dierdre O. Turner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The human papillomavirus (HPV) is the cause of nearly all cases of cervical cancers worldwide. HPV viral DNA is found in more than 99% of cervical cancers. In addition to cervical cancer, HPV is also associated with some breast and oral cancers. White women have been showing a decline in breast cancer rates while black women are continuously showing higher rates of mortality from both breast and cervical cancer. Minority women are also more likely to receive a late diagnosis and are showing increased incidence of oral cancer, which makes study of HPV in women and minorities significant.

Impact Of Adjuvants On The Antibody Responses To Pre-Pandemic H5n1 Influenza Vaccines, Ali Hassan Ellebedy

Theses and Dissertations (ETD)

Human influenza pandemics occur when influenza viruses to which the population has little or no immunity emerge and acquire the ability to transmit among humans. Since their emergence in 1996, human infections with highly pathogenic avian influenza A (H5N1) viruses presented a serious public health challenge. Additionally, H5N1 viruses caused significant agricultural and economic losses in the communities it has affected. Human infections with these viruses are rare but when they occur, these infections are highly fatal. A greater public health concern stems from the rapid evolution displayed by these viruses so far, which in turn might result in viruses …

Aids/Hiv Denialism: Patients’ Privacy Rights, Fadia Abdullah, Guadalupe Medrano

Festival of Communities: UG Symposium (Posters)

HIV is a sexually transmitted disease that develops into AIDS. There is no cure for it, only treatment. In this poster, we look at the pros and cons of disclosing this type of information. People who decide to disclose their HIV status may have various reasons for doing so, but most do it for emotional support and for prevention of spreading the disease. Those who decide to keep it private primarily do it to not face rejection, discrimination, degradation, and loss of respect. (Petronio Page 72) The problem with creating a public database is that many organizations are against the …

Aids Denialism, Erika Jenel Delos Santos, Roy Llana, Jocelyn Tan

Festival of Communities: UG Symposium (Posters)

AIDS denialism is a growing issue in many parts the world. Through scholarly journal articles, book resources and other research tactics, further understanding how HIV/AIDS denialism is unethical can be distinguished. Discovering that AIDS is most prominent in South Africa explains why denialism is as critical as it is. However, the unethical aspect of AIDS denialism is in effect particularly amongst families. When a South African inhabitant realizes they have AIDS, they feel outcasted by their families due to shame. They fear as though they will be disowned because they have flaws that are unacceptable. These family values are significant …

The Analyses Of State And Federal Medical Marijuana Laws And How They Apply To Employment, Lizaveta Sergeev

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study is to analyze and discuss the current discrepancies in the legal system as it applies to medical marijuana in the employment sector. The laws regarding the legalization of medical marijuana are relatively new and have many constraints when applied to employment. On the federal level, medical marijuana remains illegal. Many states have passed some form of legislation legalizing medical marijuana. Unfortunately, only two states have laws that protect users from being discriminated in employment. This leaves employers and employees uncertain about what actions to take when dealing with medical marijuana in the employment sector.

No Significant Change In Sexual Behavior In Association With Human Papilloma Virus Vaccination In Young Girls, Wafa R.R. Al Romaih, Archana Srinivas, Said Shahtahmasebi, Hatim A. Omar

Pediatrics Faculty Publications

The first human Papilloma virus (HPV) vaccine was approved in the United States in 2006 with the potential to reduce cervical cancer and genital warts. Since then, its efficacy in preventing HPV-related cancers in both males and females has been promising. Despite CDC recommendations, opponents of the vaccine assert that vaccinating pre-adolescents and adolescents will increase their sexual activity, as well as overtly condone risky sexual behavior. We analyzed clinic data of 499 adolescents with a mean age of 16 years to explore whether vaccination led to change in sexual behavior after one year. Our results showed no statistically significant …

High-Risk Human Papillomavirus (Hpv) Screening And Detection In Normal, Healthy Patient Saliva Samples: A Pilot Cluster Randomized Study, Deirdre O. Turner, Shelley J. Williams-Cocks, Ryan Bullen, Jeremy Catmull, Jesse Falk, Daniel Martin, Jerom Mauer, Annabel E. Barber, Robert C. Wang, Shawn Gerstenberger, Karl Kingsley

Environmental & Global Health Faculty Research

Background: The human papillomaviruses (HPV) are a large family of non-enveloped DNA viruses, mainly associated with cervical cancers. Recent epidemiologic evidence has suggested that HPV may be an independent risk factor for oropharyngeal cancers. Evidence now suggests HPV may modulate the malignancy process in some tobacco- and alcohol-induced oropharynx tumors, but might also be the primary oncogenic factor for inducing carcinogenesis among some non-smokers. More evidence, however, is needed regarding oral HPV prevalence among healthy adults to estimate risk. The goal of this study was to perform an HPV screening of normal healthy adults to assess oral HPV prevalence.

Infection Of Neuronal Cells By Chlamydia Pneumoniae And Herpes Simplex Virus Type 1 Alters Expression Of Genes Associated With Alzheimer’S Disease, Morgan M. Devins, Fiora D. Zoga, Brian J. Balin, Denah M. Appelt, Susan T. Hingley

Scholarly Posters

Several studies have suggested an infectious etiology for Alzheimer’s disease (AD). We have been investigating a potential role for both Chlamydia pneumoniae and Herpes simplex virus type 1 (HSV1) in the initiation of sporadic late-onset AD. Our current study focuses on investigation of gene expression using Alzheimer-specific Real-Time PCR microarrays on RNA derived from SKNMC human neuronal cells infected with C. pneumoniae and/or HSV1. There are distinct differences in the patterns of gene regulation by the two pathogens. For example, C. pneumoniae induces expression of genes involved in amyloid production and processing, such as β-amyloid precursor protein (APP), β-site APP-cleaving …

A Comparison Of Pharmacist Travel-Health Specialists' Versus Primary Care Providers' Recommendations For Travel-Related Medications, Vaccinations, And Patient Compliance In A College Health Setting, Melissa J. Durham, Jeffery A. Goad, Lawrence S. Neinstein, Mimi Lou

Pharmacy Faculty Articles and Research

Background. Pretravel medication and vaccination recommendations and receipt were compared between primary care providers (PCPs) without special training and clinical pharmacists specializing in pretravel health.

Methods. A retrospective chart review of patients seen for pretravel health services in a pharmacist-run travel clinic (PTC) compared to PCPs at a University Student Health Center. Vaccine/medication recommendations were assessed for consistency with national/international guidelines. Medical/pharmacy records were queried to determine the receipt of medications/vaccinations.

Results. The PTC recommended antibiotics for travelers' diarrhea were given more often when indicated (96% vs 50%, p < 0.0001), and patients seen in the PTC received their medications more often (75% vs 63%, p = 0.04). PCPs prescribed more antibiotics for travelers' diarrhea that were inconsistent with guidelines (not ordered when indicated 49% vs 6%, p < 0.0001 and ordered when not indicated 21% vs 3%, p < 0.0001). The PTC prescribed antimalarials more often when indicated (98% vs 81%, p < 0.0001), while PCPs prescribed more antimalarials that were inconsistent with guidelines (not ordered when indicated 15% vs 1%, p < 0.0001 and ordered when not indicated 19% vs 2%, p < 0.0001). The PTC ordered more vaccines per patient when indicated (mean = 2.77 vs 2.31, p = 0.0012). PTC patients were more likely to receive vaccines when ordered (mean = 2.38 vs 1.95, p = 0.0039). PCPs recommended more vaccines per patient that were inconsistent with guidelines (not ordered when indicated: mean = 0.78 vs 0.12, p < 0.0001, ordered when not indicated: mean 0.18 vs 0.025, p < 0.0001).

Conclusions. A pharmacist-run pretravel health clinic can …

First Generation Of Gender And Hiv Programs: Seeking Clarity And Synergy, Judith Bruce, Nicole Haberland, Amy Joyce, Eva Roca, Tobey Nelson Sapiano

Poverty, Gender, and Youth

In the past decade, there have been expanding resources to address the underlying gender dimensions of HIV. This has been particularly urgent in sub-Saharan Africa as the female-to-male infection ratios in young populations has reached 3 to 1 and sometimes above. The phrase “gender and HIV” has become commonplace yet does not provide any specific guidance as to target audiences, content, or measurable results. It can include everything from microcredit programs for HIV-positive women, to workplace programs seeking to change negative male norms, to efforts to increase respect for diverse sexual and gender identities. This review, conducted by the Population …

Community Health Workers Can Effectively Provide Information And Referrals To People Living With Hiv In Their Communities, Population Council

Reproductive Health

A number of studies reported high levels of sexually transmitted infections among people living with HIV (PLHIV). Unfortunately, prevention interventions targeting PLHIV in the community are not common in Kenya, and most PLHIV who are not on ART have limited access to prevention information and risk-reduction counseling. The Population Council’s APHIA II Operations Research Project conducted a research project to address these gaps. This study was conducted in 2010 in collaboration with the International Center for Reproductive Health and the National AIDS and STI Control Programme. The findings show that the intervention had a number of positive outcomes and concludes …
