A Functional Type I Topoisomerase From Pseudomonas Aeruginosa, Teesta Jain, Benjamin J. Roper, Anne Grove

Faculty Publications

Background: Pseudomonas aeruginosa encodes a putative topoisomerase with sequence similarity to the eukaryotic type IB topoisomerase from Vaccinia virus. Residues in the active site are conserved, notably Tyr292 which would be predicted to form the transient covalent bond to DNA. Results: The gene encoding the P. aeruginosa topoisomerase I was cloned and expressed in E. coli. The enzyme relaxes supercoiled DNA, while a mutant containing a Tyr292 to Phe substitution at the active site was found to be catalytically inert. This is consistent with the role of Tyr in forming the covalent intermediate. Like Vaccinia topoisomerase, the P. aeruginosa topoisomerase …

Smoking Enhances Risk For New External Genital Warts In Men, Dorothy J. Wiley, David Elashoff, Emmanuel V. Masongsong, Diane M. Harper

Dartmouth Scholarship

Repeat episodes of HPV-related external genital warts reflect recurring or new infections. No study before has been sufficiently powered to delineate how tobacco use, prior history of EGWs and HIV infection affect the risk for new EGWs. Behavioral, laboratory and examination data for 2,835 Multicenter AIDS Cohort Study participants examined at 21,519 semi-annual visits were evaluated. Fourteen percent (391/2835) of men reported or were diagnosed with EGWs at 3% (675/21,519) of study visits. Multivariate analyses showed smoking, prior episodes of EGWs, HIV infection and CD4+ T-lymphocyte count among the infected, each differentially influenced the risk for new EGWs.

A Broader Liberty: Js Mill, Paternalism, And The Public’S Health, Lawrence O. Gostin, Kieran G. Gostin

O'Neill Institute Papers

Is the ‘harm principle’, famously propounded by JS Mill and widely adopted in bioethics, an appropriate principle to guide public health regulation? The harm principle limits liberty-limiting interventions to only those instances where the person poses a significant risk of harm to others. However, much of public health regulation is not primarily directed to avert risk to others, but to safeguard the health and safety of the individual him or herself. Think about regulations regarding seatbelts, motorcycle helmets, or the fluoridation of water as illustrations of pervasive public health regulations that are primarily intended to safeguard the individual’s own health …

Science, Politics, And Values: The Politicization Of Professional Practice Guidelines, Lawrence O. Gostin, John D. Kraemer

O'Neill Institute Papers

The Connecticut Attorney General’s recent allegations that the Infectious Disease Society of America violated antitrust law through its treatment guidelines for Lyme disease were neither based in sound science or appropriate legal judgment. Strong scientific evidence favors IDSA’s position that chronic infection with the etiologic agent of Lyme disease does not occur in the absence of objective signs of ongoing infection and that long-term antibiotic use to treat dubious infection, recommended in the quasi-scientific guidelines put forth by the International Lyme and Associated Diseases Society (ILADS), are of no benefit. In siding with ILADS and other chronic Lyme disease advocates, …

An Overview Of Major Health Information Technology, Public Health, Medicaid, And Cobra Provisions Of The American Recovery And Reinvestment Act Of 2009, Sara J. Rosenbaum, Melissa M. Goldstein, Taylor Burke, Phyllis Borzi, Lara Cartwright-Smith

Health Policy and Management Faculty Publications

A detailed side-by-side analysis of the individual components of the American Recovery and Reinvestment Act of 2009 (ARRA), signed into law on February 17, 2009. One of the most sweeping pieces of economic legislation ever enacted, ARRA not only provides hundreds of billions of dollars in new health and health care spending but also makes comprehensive reforms in health law and policy, particularly in the area of health information law, including health information technology (HIT) adoption and health information privacy.

Huntington Disease (Chorea) In The Middle East, Euan M. Scrimgeour

Sultan Qaboos University Medical Journal

Huntington disease (HD) has been reported in Arab families in several Middle East countries including Saudi Arabia, Oman, Syria, Lebanon, and Egypt and in non-Arab populations in other countries in the region. It is probably under-reported, and until now, has not been recorded in Yemen, the United Arab Emirates, Jordan or in Iraq. The Middle East has always been on the crossroads of trade and travel, and HD was probably introduced to some of these countries in previous times. The prevalence rate in Middle Eastern Arabs is estimated to vary from 3 to 4 per 100,000. Although the HD gene …

Health Care-Associated Infections: Is There An End In Sight?, Lisa Sprague

National Health Policy Forum

Health care–associated infections (HAIs) have emerged as a significant concern in policy as well as clinical circles. An HAI is an infection acquired during treatment for another condition. Some of the HAI-causing bacteria have become drug-resistant; methicillin-resistant Staphylococcus aureus, or MRSA, is a familiar example. Tied to perhaps 100,000 deaths and $20 billion in health care costs each year, HAIs have given rise to state laws, legislative proposals at the federal level, public-private initiatives, and work at the hospital system and individual hospital level. However, much remains to be done. This issue brief reviews the prevalence of HAIs and the …

Ring-Substituted 4-Hydroxy-1h-Quinolin-2-Ones: Preparation And Biological Activity, Aidan Coffey, Et. Al.

Department of Biological Sciences Publications

In the study, a series of twelve ring-substituted 4-hydroxy-1H-quinolin-2-one derivatives were prepared. The procedures for synthesis of the compounds are presented. The compounds were analyzed using RP-HPLC to determine lipophilicity and tested for their photosynthesis-inhibiting activity using spinach (Spinacia oleracea L.) chloroplasts. All the synthesized compounds were also evaluated for antifungal activity using in vitro screening with eight fungal strains. For all the compounds, the relationships between the lipophilicity and the chemical structure of the studied compounds are discussed, as well as their structure-activity relationships (SAR).

Pathogenic Adaptation Of Intracellular Bacteria By Rewiring A Cis-Regulatory Input Function, Suzanne E. Osborne, Don Walthers, Ana M. Tomljenovic, David T. Mulder, Uma Silphaduang, Nancy Duong, Michael J. Lowden

Dartmouth Scholarship

The acquisition of DNA by horizontal gene transfer enables bacteria to adapt to previously unexploited ecological niches. Although horizontal gene transfer and mutation of protein-coding sequences are well-recognized forms of pathogen evolution, the evolutionary significance of cis-regulatory mutations in creating phenotypic diversity through altered transcriptional outputs is not known. We show the significance of regulatory mutation for pathogen evolution by mapping and then rewiring a cis-regulatory module controlling a gene required for murine typhoid. Acquisition of a binding site for the Salmonella pathogenicity island-2 regulator, SsrB, enabled the srfN gene, ancestral to the Salmonella genus, to play a …

Thermal Inactivation Of Bacillus Anthracis Using Laser Irradiation Of Micro-Etched Platforms, Jeffrey B. Bacon

Theses and Dissertations

The purpose of this research was to determine the probability of kill for a thermal inactivation strategy for use against biological agents; specifically the resilient endospore of Bacillus anthracis (Ba). The effort focused on short durations (milliseconds to several seconds) and temperatures (300 to 1300 K) simulating the periphery effects after an explosion generated by conventional munitions. For an improved statistical counting, applied microlithography techniques were used to produce micro-etched glass platforms consisting of 532 circular sample wells, evenly spaced. Small carbon black radiators, which provide fast heating/cooling rate and confined temperature distribution, were produced by populating the etched wells …

Living In Rural New England Amplifies The Risk Of Depression In Patients With Hiv, Siddharth H. Sheth, Paul T. Jensen, Timothy Lahey

Dartmouth Scholarship

The importance of depression as a complication of HIV infection is increasingly understood, and people living in rural areas are at increased risk for depression. However, it is not known whether living in rural areas amplifies the risk of depression in patients with HIV. We compared the prevalence of depression between rural and metropolitan HIV patients seen at the Dartmouth-Hitchcock HIV Program in a retrospective cohort study. Using the validated Rural-Urban Commuting Area Score, we categorized patients as living in small town/rural areas, micropolitan or metropolitan towns. Then, using a multivariate logistic regression model to adjust for demographic factors that …

Religion And Hiv In Tanzania: Influence Of Religious Beliefs On Hiv Stigma, Disclosure, And Treatment Attitudes, James Zou, Yvonne Yamanaka, Muze John, Melissa Watt, Jan Ostermann, Nathan Thielman

Faculty Publications

Background

Religion shapes everyday beliefs and activities, but few studies have examined its associations with attitudes about HIV. This exploratory study in Tanzania probed associations between religious beliefs and HIV stigma, disclosure, and attitudes toward antiretroviral (ARV) treatment.

Methods

A self-administered survey was distributed to a convenience sample of parishioners (n = 438) attending Catholic, Lutheran, and Pentecostal churches in both urban and rural areas. The survey included questions about religious beliefs, opinions about HIV, and knowledge and attitudes about ARVs. Multivariate logistic regression analysis was performed to assess how religion was associated with perceptions about HIV, HIV treatment, and …

Vaccines And Autism: The Evidence And The Law, Alexandra M. Stewart

Health Policy and Management Faculty Publications

A potential link between the measles-mumps-rubella vaccine and autism was dismissed by a federal vaccine court in February 2009. The U.S. Department of Health and Human Services said the findings demonstrate a lack of medical evidence for any association, while Autism Speaks, a patient advocacy group, said questions remain about potential risks for certain subgroups.

Other legal actions are pending as the scientific and patient advocacy communities debate the need to conduct further research on the vaccine-autism link. Meanwhile, public health advocates worry that continuing concerns about the safety of vaccines may depress the population immunization rate. A small rise …

Detection Of Novel Sars-Like And Other Coronaviruses In Bats From Kenya, Suxiang Tong, Christina Conrardy, Sujsan Ruone

KIP Articles

Diverse coronaviruses have been identified in bats from several continents but not from Africa. We identified group 1 and 2 coronaviruses in bats in Kenya, including SARS-related coronaviruses. The sequence diversity suggests that bats are well-established reservoirs for and likely sources of coronaviruses for many species, including humans.

Fisheries Occasional Publication No.057 - Introduced Marine Species In Western Australia, Department Of Fisheries Western Australia

Fisheries Occasional Publications

As the largest State in Australia, Western Australia (WA) has a long and relatively pristine coastline that stretches over 12,500 km, or over 20,700 km if the State’s 3,747 islands are included. The coast ranges over 20 degrees of latitude from the temperate south coast to the northern tip of the tropical Kimberley. There are a wide variety of coastal marine habitats in this vast area. The south coast has extensive white sandy beaches interspersed with granite headlands. A diverse range of nearly 800 species of temperate marine algae, or seaweeds, occurs in the area. With 26 species, the seagrasses …

Growth-Regulated Expression Of A Bacteriocin, Produced By The Sweet Potato Pathogen Streptomyces Ipomoeae, That Exhibits Interstrain Inhibition, Jing Wang, Kevin L. Schultyp, Gregg S. Pettis

Faculty Publications

Certain strains of the bacterial sweet potato pathogen Streptomyces ipomoeae produce the bacteriocin ipomicin, which inhibits other sensitive strains of the same species. Within the signal-sequence-encoding portion of the ipomicin structural gene ipoA exists a single rare TTA codon, which is recognized in Streptomyces bacteria by the temporally accumulating bldA leucyl tRNA. In this study, ipomicin was shown to stably accumulate in culture supernatants of 5. ipomoeae in a growth-regulated manner that did not coincide with the pattern of ipoA expression. Similar growth-regulated production of ipomicin in Streptomyces coelicolor containing the cloned ipoA gene was found to be directly dependent …
