Strong Genetic Differentiation Between North American And European Populations Of Phytophthora Alni Subsp. Uniformis, Jaime Aguayo, Gerard C. Adams, Fabien Halkett, Mursel Catal, Claude Husson, Zoltán Á. Nagy, Everett M. Hansen, Benoît Marçais, Pascal Frey

Department of Plant Pathology: Faculty Publications

Alder decline caused by Phytophthora alni has been one of the most important diseases of natural ecosystems in Europe during the last 20 years. The emergence of P. alni subsp. alni—the pathogen responsible for the epidemic—is linked to an interspecific hybridization event between two parental species: P. alni subsp. multiformis and P. alni subsp. uniformis. One of the parental species, P. alni subsp. uniformis, has been isolated in several European countries and, recently, in North America. The objective of this work was to assess the level of genetic diversity, the population genetic structure, and the putative reproduction …

Inflammatory Biomarker Changes And Their Correlation With Framingham Cardiovascular Risk And Lipid Changes In Antiretroviral-Naive Hiv-Infected Patients Treated For 144 Weeks With Abacavir/Lamivudine/Atazanavir With Or Without Ritonavir In Aries., Benjamin Young, Kathleen E Squires, Lisa L Ross, Lizette Santiago, Louis M Sloan, Henry H Zhao, Brian C Wine, Gary E Pakes, David A Margolis, Mark S Shaefer

Division of Infectious Diseases and Environmental Medicine Faculty Papers

Propensity for developing coronary heart disease (CHD) is linked with Framingham-defined cardiovascular risk factors and elevated inflammatory biomarkers. Cardiovascular risk and inflammatory biomarkers were evaluated in ARIES, a Phase IIIb/IV clinical trial in which 515 antiretroviral-naive HIV-infected subjects initially received abacavir/lamivudine + atazanavir/ritonavir for 36 weeks. Subjects who were virologically suppressed by week 30 were randomized 1:1 at week 36 to either maintain or discontinue ritonavir for an additional 108 weeks.

The Kaposi's Sarcoma-Associated Herpesvirus Orf34 Protein Binds To Hif-1Α And Causes Its Degradation Via The Proteasome Pathway, Muzammel Haque, Konstantin G. Kousoulas

Faculty Publications

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent for Kaposi's sarcoma (KS) and two other lymphoproliferative disorders, primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD). Kaposi's sarcoma is a highly vascular tumor, and recently both hypoxia-inducible factor 1α (HIF-1α) and HIF-2α were detected in KS samples, indicating a role of HIFs in the KSHV life cycle. Previously, we showed that ORF34, a lytic gene of unassigned function, was activated by hypoxia and that ORF34 transcription was upregulated by both HIFs (M. Haque, D. A. Davis, V. Wang, I. Widmer, and R. Yarchoan, J Virol. 77:6761- 6768, 2003). In the …

Lysine Biosynthesis In Bacteria: A Metallodesuccinylase As A Potential Antimicrobial Target, Danuta M. Gillner, Daniel P. Becker Ph.D., Richard C. Holz

Chemistry: Faculty Publications and Other Works

In this review, we summarize the recent literature on dapE-encoded N-succinyl-l,l-diaminopimelic acid desuccinylase (DapE) enzymes, with an emphasis on structure–function studies that provide insight into the catalytic mechanism. Crystallographic data have also provided insight into residues that might be involved in substrate and hence inhibitor recognition and binding. These data have led to the design and synthesis of several new DapE inhibitors, which are described along with what is known about how inhibitors interact with the active site of DapE enzymes, including the efficacy of a moderately strong DapE inhibitor.

Inhibition Of Herpes Simplex Virus Type 1 With The Modified Green Tea Polyphenol Palmitoyl-Epigallocatechin Gallate, Aline De Oliveira, Sandra Adams, Lee Lee, Sean R. Murray, Stephen D. Hsu, Jeffrey R. Hammond, Douglas Dickinson, Ping Chen, Tin Chun Chu

Department of Biology Faculty Scholarship and Creative Works

Green tea polyphenol epigallocatechin gallate (EGCG) is a strong antioxidant that has previously been shown to reduce the number of plaques in HIV-infected cultured cells. Modified EGCG, palmitoyl-EGCG (p-EGCG), is of interest as a topical antiviral agent for herpes simplex virus (HSV-1) infections. This study evaluated the effect of p-EGCG on HSV-infected Vero cells. Results of cell viability and cell proliferation assays indicate that p-EGCG is not toxic to cultured Vero cells and show that modification of the green tea polyphenol epigallocatechin gallate (EGCG) with palmitate increases the effectiveness of EGCG as an antiviral agent. Furthermore, p-EGCG is a more …

Review Of Haploporid (Trematoda) Genera With Ornate Muscularization In The Region Of The Oral Sucker, Including Four New Species And A New Genus, Eric E. Pulis, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Species of the Haploporidae Nicoll, 1914 with elaborate muscularization of the oral sucker belong in three trematode genera, including three new species and a new genus from the intestine of fishes in Australian waters. Spiritestis Nagaty, 1948 is resurrected and S. herveyensis n. sp. is described from the mullet Moolgarda seheli (Forsskål) collected in Hervey Bay, Queensland, Australia; the latter differs from S. arabii Nagaty, 1948 in that the position of the genital pore is pharyngeal rather than post-pharyngeal and the geographical range is off Australia rather than the Red Sea. A new genus is proposed for two new species, …

Frequent Cross-Species Transmission Of Parvoviruses Among Diverse Carnivore Hosts, Andrew B. Allison, Dennis J. Kohler, Karen A. Fox, Justin D. Brown, Richard W. Gerhold, Valerie I. Shearn-Bochsler, Edward J. Dubovi, Colin R. Parrish, Edward C. Holmes

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Although parvoviruses are commonly described in domestic carnivores, little is known about their biodiversity in nondomestic species. A phylogenetic analysis of VP2 gene sequences from puma, coyote, gray wolf, bobcat, raccoon, and striped skunk revealed two major groups related to either feline panleukopenia virus (“FPV-like”) or canine parvovirus (“CPV-like”). Crossspecies transmission was commonplace, with multiple introductions into each host species but, with the exception of raccoons, relatively little evidence for onward transmission in nondomestic species.

Evaluating Audio Computer Assisted Self-Interviews In Urban South African Communities: Evidence For Good Suitability And Reduced Social Desirability Bias Of A Cross-Sectional Survey On Sexual Behaviour, Roxanne Beauclair, Fei Meng, Nele Deprez, Marleen Temmerman, Alex Welte, Wim Delva, Niel Hens

Obstetrics and Gynaecology, East Africa

Background: Efficient HIV prevention requires accurate identification of individuals with risky sexual behaviour. However, self-reported data from sexual behaviour surveys are prone to social desirability bias (SDB). Audio Computer-Assisted Self-Interviewing (ACASI) has been suggested as an alternative to face-to-face interviewing (FTFI), because it may promote interview privacy and reduce SDB. However, little is known about the suitability and accuracy of ACASI in urban communities with high HIV prevalence in South Africa. To test this, we conducted a sexual behaviour survey in Cape Town, South Africa, using ACASI methods.

Methods: Participants (n = 878) answered questions about their sexual relationships on …

Vibrio Cholerae Exploits Sub-Lethal Concentrations Of A Competitor-Produced Antibiotic To Avoid Toxic Interactions, Jason R. Graff, Stephanie Forschner-Dancause, Susanne Menden-Deuer, Richard A. Long, David C. Rowley

Graduate School of Oceanography Faculty Publications

Vibrio cholerae is a human pathogenic marine bacterium inhabiting coastal regions and is vectored into human food and water supplies via attachment to particles including detritus, phytoplankton, and zooplankton. Particle colonization by the pathogen is inhibited by an antagonistic interaction with the particle-associated Vibrionales bacterium SWAT3, a producer of the antibiotic andrimid. By analyzing the individual movement behaviors of V. cholerae exposed to a gradient of andrimid in a microfluidics device, we show that the pathogen has a concentration dependent avoidance response to sub-lethal concentrations of the pure antibiotic and to the metabolites produced by a growing colony of SWAT3-wild-type. …

Physical Activity And Modernization Among Bolivian Amerindians, Michael Gurven, Adrian V. Jaeggi, Hillard Kaplan, Daniel Cummings

ESI Publications

Background: Physical inactivity is a growing public health problem, and the fourth leading risk factor for global mortality. Conversely, indigenous populations living traditional lifestyles reportedly engage in vigorous daily activity that is protective against non-communicable diseases. Here we analyze physical activity patterns among the Tsimane, forager-horticulturalists of Amazonian Bolivia with minimal heart disease and diabetes. We assess age patterns of adult activity among men and women, test whether modernization affects activity levels, and examine whether nascent obesity is associated with reduced activity.

Methods and Findings: A factorial method based on a large sample of behavioral observations was employed …

Biodiversity loss and climate change secondary to human activities are now being associated with various adverse health effects. However, less attention is being paid to the effects of biodiversity loss on environmental and commensal (indigenous) microbiotas. Metagenomic and other studies of healthy and diseased individuals reveal that reduced biodiversity and alterations in the composition of the gut and skin microbiota are associated with various inflammatory conditions, including asthma, allergic and inflammatory bowel diseases (IBD), type1 diabetes, and obesity. Altered indigenous microbiota and the general microbial deprivation characterizing the lifestyle of urban people in affluent countries appear to be risk factors …

Medicine Faculty Publications

Background

Cachexia is a hallmark of pulmonary tuberculosis and is associated with poor prognosis. A better understanding of the mechanisms behind such weight loss could reveal targets for therapeutic intervention. The role of appetite-regulatory hormones in tuberculosis is unknown.

Methods and Findings

41 subjects with newly-diagnosed pulmonary TB (cases) were compared to 82 healthy controls. We measured appetite, body mass index (BMI), % body fat (BF), plasma peptide YY (PYY), leptin, ghrelin, and resistin for all subjects. Measurements were taken at baseline for controls and at treatment days 0, 30, and 60 for cases. Baseline appetite, BMI, and BF were …

Automated Point-Of-Care Image Processing Methodology For The Diagnosis Of Malaria, Michael B. Jorgensen

Master's Theses

Malaria has profoundly influenced human history for over four thousand years and despite numerous attempts at eradication, the prevention, diagnosis, and treatment of malaria have been largely ineffective. More than five hundred million people are affected by malaria every year resulting in over one million deaths. Drug resistance development by the parasite has diminished the effectiveness of numerous treatment options due, in part, to overtreatment of negative patients based on insufficient clinical algorithms and diagnostic methods. The goal of this research was to develop an image analysis algorithm to diagnose malaria with a high degree of sensitivity and specificity in …

Nuclear Envelope Composition Determines The Ability Of Neutrophil-Type Cells To Passage Through Micron-Scale Constrictions, Amy C. Rowat, Diana E. Jaalouk E. Jaalouk, Monika Zwerger, W. Lloyd Ung, Irwin A. Eydelnant, Donald E. Olins, Ada L. Olins, Harald Herrmann, David A. Weitz, Jan Lammerding

Pharmaceutical Sciences Faculty Publications

Neutrophils are characterized by their distinct nuclear shape, which is thought to facilitate the transit of these cells through pore spaces less than one-fifth of their diameter. We used human promyelocytic leukemia (HL-60) cells as a model system to investigate the effect of nuclear shape in whole cell deformability. We probed neutrophil-differentiated HL-60 cells lacking expression of lamin B receptor, which fail to develop lobulated nuclei during granulopoiesis and present an in vitro model for Pelger-Huët anomaly; despite the circular morphology of their nuclei, the cells passed through micron-scale constrictions on similar timescales as scrambled controls. We then investigated the …

Faktor Risiko Diare Shigellosis Pada Anak Balita, A. Zulkifli Abdullah, A. Arsunan Arsin, Lidyawati Dahlan

Kesmas

Diare shigellosis pada balita merupakan masalah serius sebab dapat menyebabkan kematian. Untuk mengetahui faktor-faktor risiko kejadian shigellosis pada anak balita dilakukan studi kasus kontrol di beberapa rumah sakit di Kota Makassar dengan 68 kasus dan 136 kontrol. Data mengenai jenis kelamin dan status gizi anak balita, pemberian air susu ibu (ASI) eksklusif, status ekonomi, pendidikan ibu, kebiasaan ibu mencuci tangan memakai sabun, kepadatan hunian rumah, sarana air bersih, danjamban keluarga dikumpulkan dengan wawancara dan observasi serta dikategorikan dan disaring (screening) dengan uji chi square. Enam variabel dengan nilai p < 0,25 dimasukkan dalam uji regresi logistik yang menghasilkan variabel dengan nilai p < 0,05 (gizi rendah, ASI tidak eksklusif, dan status ekonomi rendah). Uji regresi logistik tahap kedua dengan 3 variabel ini menghasilkan model shigellosis = 1,47 gizi rendah + 1,471 ASI tidak eksklusif + 1,022 status ekonomi rendah - 2,546 dengan nilai oddsratio (OR) = 4,352 (gizi rendah), 4,353 (ASI tidak eksklusif), dan 2,779 (status ekonomi rendah). Studi ini menyimpulkan bahwa gizi balita yang rendah, pemberian ASI yang tidak eksklusif, dan status ekonomi ibu yang rendah merupakan faktor-faktor risiko penting kejadian diare shigellosis pada balita.

Neuropsychiatric Effects Of Tenofovir In Comparison With Other Antiretroviral Drugs., Kathleen Ferrer, Natella Rakhmanina

Pediatrics Faculty Publications

Tenofovir is a widely used antiretroviral medication indicated to treat adults and children infected with HIV. Current guidelines for the management of HIV infection recommend tenofovir disoproxil fumarate (TDF) as a component of the preferred first-line combination antiretroviral therapy. The efficacy, tolerability, prolonged half-life allowing for once-daily administration, and availability as a component of several fixed-dose formulations make TDF an attractive choice for treatment-naive and treatment-experienced HIV-infected patients. TDF is also widely used as a component of postexposure prophylaxis in noninfected individuals. Most importantly, it has been recently approved for use as pre-exposure prophylaxis for noninfected adults and adolescents to …
