Purification Of A Serine Protease And Evidence For A Protein C Activator From The Saliva Of The Tick, Ixodes Scapularis, Sivakamasundari Pichu, José M.C. Ribeiro, Thomas N. Mather, Ivo M.B. Francischetti

Plant Sciences and Entomology Faculty Publications

The saliva of ticks is critical to their survival as parasites and hematophagous animals. In this study, we have purified an enzyme with trypsin-like activity from the saliva of the tick vector of Lyme Disease, Ixodes scapularis. This enzyme, named as IXOSP (I. scapularis salivary serine protease), is a 29.9 kDa molecule with N-terminus FPxMVxLRIKxR. A BLAST search identified IXOSP as a secreted serine protease (AAY66740) with a conserved catalytic triad His, Asp, and Ser. In vitro studies demonstrated that IXOSP cleaves chromogenic substrates with arginine in the P₁ position, by a mechanism inhibited by PMSF or …

Probiotics: Achieving A Better Regulatory Fit, Diane E. Hoffmann, Claire M. Fraser, Francis Palumbo, Jacques Ravel, Virginia Rowthorn, Jack Schwartz

Faculty Scholarship

In 2007, the National Institutes of Health (NIH) launched the Human Microbiome Project (HMP), a $150 million initiative to characterize the microbial communities found at several different sites on the human body and to analyze the role of these microbes in human health and disease. Many lines of research have demonstrated the significant role of the microbiota in human physiology. The microbiota is involved, for example, in the healthy development of the immune system, prevention of infection from pathogenic or opportunistic microbes, and maintenance of intestinal barrier function. The HMP findings are helping us understand the role and variation of …

Central Nervous System Infections Masquerading As Cerebrovascular Accidents: Case Series And Review Of Literature, L. Hayes, P. Malhotra

Journal Articles

AbstractIntroduction Central nervous system (CNS) infections can have various presentations including Cerebrovascular accidents (CVA) which may go unrecognized as a presentation of infection. We describe three cases of different CNS infections complicated by CVA. Presentation Case 1 describes a 27-year-old man, presenting with symptoms consistent with a transient ischemic attack found to have racemose neurocysticercosis. Case 2 describes a 55-year-old man with low grade fevers for 4 weeks accompanied by visual and gait disturbances and delayed speech diagnosed with multiple small left thalamocapsular and superior cerebellar infarcts secondary to cryptococcal meningitis. The third case describes a man with pneumococcal meningitis …

A New System For Naming Ribosomal Proteins, N. Ban, R. Beckmann, J. H. D. Cate, J. D. Dinman, F. Dragon, S. R. Ellis, D. L. J. Lafontaine, L. Lindahl, J. M. Lipton, M. Yusupov, +15 Additional Authors

Journal Articles

A system for naming ribosomal proteins is described that the authors intend to use in the future. They urge others to adopt it. The objective is to eliminate the confusion caused by the assignment of identical names to ribosomal proteins from different species that are unrelated in structure and function. In the system proposed here, homologous ribosomal proteins are assigned the same name, regardless of species. It is designed so that new names are similar enough to old names to be easily recognized, but are written in a format that unambiguously identifies them as 'new system' names.

Journal Articles

This study addressed whether psychopharmacologic and psychotherapeutic treatment of depressed HIV+ women met standards defined in the best practice literature, and tested hypothesized predictors of standard-concordant care. 1,352 HIV-positive women in the multi-center Women's Interagency HIV Study were queried about depressive symptoms and mental health service utilization using standards published by the American Psychiatric Association and the Agency for Healthcare Research and Quality to define adequate depression treatment. We identified those who: (1) reported clinically significant depressive symptoms (CSDS) using Centers for Epidemiological Studies-Depression Scale scores of a parts per thousand yen16; or (2) had lifetime diagnoses of major depressive …

Low Vitamin D Level Is An Independent Predictor Of Poor Outcomes In Clostridium Difficile-Associated Diarrhea, W. J. Wang, S. Gray, C. Sison, S. Arramraju, B. K. John, S. A. Hussain, S. H. Kim, P. Mehta, M. Rubin

Journal Articles

Background: The incidence, recurrence, and all-cause mortality rate for Clostridium difficile-associated diarrhea (CDAD) has increased markedly over the past 10 years despite treatment. Low vitamin D levels are known to impair immune responses to infection and are associated with increased mortality. We compared the role of patient comorbidity measured by the Charlson Comorbidity Index (CCI) with vitamin D levels to ascertain whether vitamin D levels were an independent variable affecting the outcome of CDAD or a marker of overall comorbidity. Methods: A prospective cohort study studied 62 patients hospitalized between 2008 and 2009 with manifestations of CDAD and a positive …

Forever New: The Speeches Of James Wright, President Of Dartmouth College, 1998-2009, James Edward Wright, Sheila Culbert

Dartmouth College Press

About the Book

(from upne.com) Jim Wright is an unabashed optimist. Reading his speeches, it doesn't take long to see that he believes in the fundamental values that shaped the American republic: opportunity and accessibility, individuality and a shared sense of community. He carried this idealism into his presidency of Dartmouth College and, indeed, throughout his career as teacher and historian. At heart, Jim Wright was always a teacher. His election to the presidency of Dartmouth College gave him the opportunity not only to lead the college he loved, but also to use the presidency as a bully pulpit to …

Developing Clinical Strength-Of-Evidence Approach To Define Hiv-Associated Malignancies For Cancer Registration In Kenya, Anne Korir, Nathan Mauti, Pamela Moats, Matthew J. Gurka, Geoffrey Mutuma, Christine Metheny, Peter M. Mwamba, Peter O. Oyiro, Melanie Fisher, Leona W. Ayers, Rosemary Rochford, Walter O. Mwanda, Scot C. Remick

Faculty & Staff Scholarship

Background

Sub-Saharan Africa cancer registries are beset by an increasing cancer burden further exacerbated by the AIDS epidemic where there are limited capabilities for cancer-AIDS match co-registration. We undertook a pilot study based on a “strength-of-evidence” approach using clinical data that is abstracted at the time of cancer registration for purposes of linking cancer diagnosis to AIDS diagnosis.

Methods/Findings

The standard Nairobi Cancer Registry form was modified for registrars to abstract the following clinical data from medical records regarding HIV infection/AIDS in a hierarchal approach at time of cancer registration from highest-to-lowest strength-of-evidence: 1) documentation of positive HIV serology; 2) …

A High Throughput Mhc Ii Binding Assay For Quantitative Analysis Of Peptide Epitopes, Regina Salvat, Leonard Moise, Chris Bailey-Kellogg, Karl E. Griswold

Cell and Molecular Biology Faculty Publications

Biochemical assays with recombinant human MHC II molecules can provide rapid, quantitative insights into immunogenic epitope identification, deletion, or design^1,2. Here, a peptide-MHC II binding assay is scaled to 384-well format. The scaled down protocol reduces reagent costs by 75% and is higher throughput than previously described 96-well protocols^1,3-5. Specifically, the experimental design permits robust and reproducible analysis of up to 15 peptides against one MHC II allele per 384-well ELISA plate. Using a single liquid handling robot, this method allows one researcher to analyze approximately ninety test peptides in triplicate over a range of eight …

Horses As Sources Of Proprietary Information: Commercialization, Conservation, And Compensation Pursuant To The Convention On Biological Diversity, Haley Mcclory, Stanley Kowalski

Law Faculty Scholarship

Horses indigenous to East and Southeast (E/SE) Asia, including native, landrace, feral, and wild populations, embody valuable genetic diversity. Conservation efforts for animals have largely been driven by humane altruism, with little consideration for the information value of genomes. Yet, if horses are viewed as archives of information as well as objects of affection, their conservation shifts to a market-based paradigm. Horse genetic resources (GR) likely contain significant value to the lucrative global horse industry, including veterinary applications such as diagnostics, therapeutics, genetic markers, gene therapies, and cloning technologies. As biotechnology becomes increasingly sophisticated, mining of horse GR will accelerate, …

Mutations In The Gene That Encodes The F-Actin Binding Protein Anillin Cause Fsgs, R. A. Gbadegesin, G. Hall, A. Adeyemo, N. Hanke, I. Tossidou, J. Burchette, G. H. Wu, A. Homstad, P. C. Singhal, M. P. Winn, +17 Additional Authors

Journal Articles

FSGS is characterized by segmental scarring of the glomerulus and is a leading cause of kidney failure. Identification of genes causing FSGS has improved our understanding of disease mechanisms and points to defects in the glomerular epithelial cell, the podocyte, as a major factor in disease pathogenesis. Using a combination of genome-wide linkage studies and whole-exonne sequencing in a kindred with familial FSGS, we identified a missense mutation R431C in anillin (ANLN), an F-actin binding cell cycle gene, as a cause of FSGS. We screened 250 additional families with FSGS and found another variant, G618C, that segregates with disease in …

Psychosocial Correlates Of Gender-Based Violence Among Hiv-Infected And Hiv-Uninfected Women In Three Us Cities, R. M. Schwartz, K. M. Weber, G. E. Schechter, N. C. Connors, Y. Gousse, M. A. Young, M. H. Cohen

Journal Articles

Gender-based violence (GBV) is common among women with and at risk for HIV, yet little is known about the GBV associated psychological factors that could be modifiable through behavioral interventions. The current study examined the associations between some of these psychological factors (i.e., hopelessness, consideration of future consequences, self esteem), mental health symptoms, substance abuse, and GBV among a sample of 736 HIV-infected and sociodemographically similar uninfected participants in the Women's Interagency HIV Study (WIHS). Results indicated high rates of lifetime GBV among the sample (58%), as well as high rates of childhood sexual abuse (CSA) (22.2%). HIV-infected women were …

Beyond Donors And Dollars: An Ethnographic Case Study Of International Aid And Its Agents In Mozambique, Carly Amanda Santoro

Electronic Theses and Dissertations

In Mozambique, international non-governmental organizations (INGOs) work mainly in Mozambique's rural areas, with programs dedicated to the prevention of infectious diseases, education, access to food and clean water, gender equity, and many other concerns. Yet despite these efforts, Mozambican populations are critical of NGOs' missions and practices, and Mozambique remains one of the poorest countries in the world. To explore these issues concerning contradictions in aid in Mozambique, I employ the concept of cultural capital, which refers to cultural practices, perspectives, and beliefs in relation to one's ability to access symbolic and material goods. My thesis examines the degree to …

Cmvil-10 Stimulates The Invasive Potential Of Mda-Mb-231 Breast Cancer Cells, Cendy Valle Oseguera, Juliet Spencer

Biology Faculty Publications

Cancer is the result of unregulated cell growth that leads to tumor formation, and in many cases, metastases. Although there are several risk factors associated with cancer, one area that remains poorly understood is the impact of infectious disease. Human cytomegalovirus (HCMV) is a member of the herpesvirus family that is highly prevalent in the population. HCMV usually causes clinical disease only in immune compromised individuals, but recent evidence suggests that HCMV may be strongly associated with some forms of cancer, particularly glioblastoma and breast cancer. We investigated the possibility that cmvIL-10, a viral cytokine with homology to human IL-10 …
