Indirect Evidence Of Density-Dependent Population Regulation In Aponomma Hydrosauri (Acari: Ixodidae), An Ectoparasite Of Reptiles, Andrew J. Tyre, C. Michael Bull, Brigitte Tenhumberg, Neil Chilton

School of Natural Resources: Faculty Publications

The extent to which density-dependent processes regulate natural populations is the subject of an ongoing debate. We contribute evidence to this debate showing that density-dependent processes influence the population dynamics of the ectoparasite Aponomma hydrosauri (Acari: Ixodidae), a tick species that infests reptiles in Australia. The first piece of evidence comes from an unusually long-term dataset on the distribution of ticks among individual hosts. If density-dependent processes are influencing either host mortality or vital rates of the parasite population, and those distributions can be approximated with negative binomial distributions, then general host– parasite models predict that the aggregation coefficient of …

Ethical And Legal Standards For Research In Prisons, Karen C. Kalmbach, Phillip M. Lyons

Psychology Faculty Publications (Archived)

Biobehavioral research, especially that which is conducted with prisoners, has become much more closely regulated in the last 30 years. State and federal law, as well as professional standards, regulate the conduct of many types of research; in the case of prisoners, this regulation is even more stringent. However, currently no mandatory, uniform, national regulatory or oversight process exists, and many privately funded research endeavors are operating in a regulatory void. In response to this, the National Bioethics Advisory Commission has argued for the creation of a single, national, independent regulatory body to oversee all human participant research, regardless of …

Human Health Effects Of A Changing Global Nitrogen Cycle, Alan R. Townsend, Robert W. Howarth, Fakhri A. Bazzaz, Mary S. Booth, Cory C. Cleveland, Sharon K. Collinge, Andrew P. Dobson, Paul R. Epstein, Elisabeth A. Holland, Dennis R. Keeney, Michael A. Mallin, Christine A. Rogers, Peter Wayne, Amir H. Wolfe

Ecosystem and Conservation Sciences Faculty Publications

Changes to the global nitrogen cycle affect human health well beyond the associated benefits of increased food production. Many intensively fertilized crops become animal feed, helping to create disparities in world food distribution and leading to unbalanced diets, even in wealthy nations. Excessive air- and water-borne nitrogen are linked to respiratory ailments, cardiac disease, and several cancers. Ecological feedbacks to excess nitrogen can inhibit crop growth, increase allergenic pollen production, and potentially affect the dynamics of several vector-borne diseases, including West Nile virus, malaria, and cholera. These and other examples suggest that our increasing production and use of fixed nitrogen …

Sulfolipid Deficiency Does Not Affect The Virulence Of Mycobacterium Tuberculosis H37rv In Mice And Guinea Pigs, Cécile Rousseau, Oliver C. Turner, Erik Rush, Yann Bordat, Tatiana D. Sirakova, Pappachan E. Kolattukudy, Shannon Ritter, Ian M. Orme, Brigitte Gicquel, Mary Jackson

Faculty Bibliography 2000s

Lipids that are found only in the cell envelope of pathogenic mycobacteria, such as those containing multiple methyl-branched fatty acids, have long been thought to play a role in pathogenesis. Among these complex lipids, sulfolipids have been the most extensively studied over the last 50 years. The numerous biological effects exhibited by purified sulfolipids on phagocytic cells led to the idea that these molecules are probably important virulence factors facilitating the intracellular survival of Mycobacterium tuberculosis. However, definitive evidence to support this concept has been lacking. The recent construction of an isogenic sulfolipid-deficient mutant of M. tuberculosis H37Rv (Sirakova et …

Cloning Of Hbsag-Encoded Genes In Different Vectors And Their Expression In Eukaryotic Cells, Shan Qin, Hong Tang, Lian-San Zhao, Fang He, Yong Lin, Li Liu, Xiao-Mei He

Faculty Bibliography 2000s

AIM: To compare the efficiency of different plasmids as DNA vectors by cloning three HBsAg-encoded genes into two eukaryotic expression vectors, pRc/CMV and pSG5UTPL/Flag, and to express HBsAg S, MS, and LS proteins in SP2/0 cells, and to establish monoclone SP2/0 cell strains that are capable of expressing S or S2S proteins stably. METHODS: Segments of S, preS2-S, preS1-preS2-S genes of Hepatitis B virus were amplified by routine PCR and preS1-S fragment was amplified by Over-Lap Extension PCR. The amplified segments were cleaved with restricted endonuclease Hind III/Not I followed by ligation with pRc/CMV, or BamHI/EcoR I followed by ligation …

The Largest Open Reading Frame (Pks12) In The Mycobacterium Tuberculosis Genome Is Involved In Pathogenesis And Dimycocerosyl Phthiocerol Synthesis, Tatianna D. Sirakova, Vinod S. Dubey, Hwa-Jung Kim, Michael H. Cynamon, Pappachan E. Kolattukudy

Faculty Bibliography 2000s

The cell wall lipids in Mycobacterium tuberculosis are probably involved in pathogenesis. The largest open reading frame in the genome of M. tuberculosis H37Rv, pks12, is unique in that it encodes two sets of domains needed to produce fatty acids. Apks12-disrupted mutant was produced, and disruption was confirmed by both PCR analysis and Southern blotting. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed that a 430-kDa protein band present in the wild type was missing in the mutant. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MS) and liquid chromatography (LC)-MS analysis of tryptic peptides showed that 54 peptides distributed …

When Terrorism Threatens Health: How Far Are Limitations On Personal And Ecomonic Liberties Justified, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The government is engaged in a homeland-security project to safeguard the population's health from potential terrorist attacks. This project is politically charged because it affords the state enhanced powers to restrict personal and economic liberties. Just as governmental powers relating to intelligence, law enforcement, and criminal justice curtail individual interests, so too do public health powers.

Response Of Blackberry Cultivars To Nematode Transmission Of Tobacco Ringspot Virus, Alisha Sanny, John R. Clark, Rose Gergerich

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A study was conducted on eight cultivars of blackberry (‘Apache’, ‘Arapaho’, ‘Chester’, ‘Chickasaw’, ‘Kiowa’, ‘Navaho’, ‘Shawnee’, and ‘Triple Crown’), of which four plants of each were previously determined in the fall of 2001 to have root, but not leaf, infection with Tobacco ringspot virus (TRSV). The objectives of our study were to determine virus effects on plant vigor and the spread of virus infection in the plants. Eight plants of each cultivar, four infected and four free of infection, were grown in pots on a gravel pad for the 2002 growing season, and samples of primocane and floricane leaves were …

The Silence Of The Labs, Don J. Deyoung

Defense Horizons

Something important to the Nation’s defense has vanished, yet the top Pentagon brass never noticed. Not the stuff of headlines, this loss would not arouse public concern, especially during these times of terrorist massacres, anthrax attacks, corporate scandal, and war. Nevertheless, like the miner’s canary that is first to die with the rush of an ill wind, this loss is a warning.

In the span of 18 months, the Department of Defense (DOD) lost a key part of its 25-year-old ability to perform fiber optics research at the Naval Research Laboratory (NRL), the only site with this world-class defense capability. …

Hemorrhagic Fever Viruses, Jeffery A. Goad, J Nguyen

Pharmacy Faculty Articles and Research

Viral hemorrhagic fever (VHF) viruses are diverse and include arenaviruses, bunyaviruses, filoviruses, and flaviviruses. Lassa fever, South American hemorrhagic fever (HF), Rift Valley HF, Crimean-Congo HF, Ebola, Marburg, yellow fever, and dengue fever are well known examples of the hemorrhagic fever viruses. They are often difficult to diagnose and treat resulting in significant morbidity and mortality. Transmission varies from vector borne to person-to-person. The common clinical presentation includes fever, myalgia, microvascular damage, and hemorrahage as well as a history of travel to the tropics. If VHF is suspected, strict infection control procedures must be implemented to prevent the spread of …

Public Health And The Built Environment: Historical, Empirical, And Theoretical Foundations For An Expanded Role, Wendy Collins Perdue, Lawrence O. Gostin, Lesley A. Stone

Law Faculty Publications

In 2000, the Center for Disease Control and Prevention's National Center for Environmental Health issued a report that explored some of the ways in which "sprawl" impacts public health. The report has generated great interest, and state health officials are beginning to discuss the relationship between land use and public health. The CDC report has also produced a backlash. For example, the Southern California Building Industry Association labeled the report "a ludicrous sham" and argued that the CDC should stick to "fighting physical diseases, not defending political ones."

In this environment, it is understandable if the CDC looks to such …

Heat Transfer In Outdoor Aquaculture Ponds, Jonathan Lamoureux

LSU Master's Theses

An energy balance was developed for heated and unheated earthen aquaculture ponds to 1) determine the relative importance of energy transfer mechanism affecting pond temperature; 2) predict pond temperatures; 3) estimate the energy required to control pond temperatures, and 4) recommend efficient heating and cooling methods. PHATR (Pond Heating and Temperature Regulation), a computer program using 4th order Runge-Kutta numerical method was developed to solve the energy balance using weather, flow rate and pond temperature data. By comparing measured and modeled pond temperatures, the average difference (the average bias) was 0.5°C for unheated ponds and 2.4°C for heated ponds. The …

The Body Politic: Burial And Post-War Reconciliation In Baton Rouge, Leah Wood Jewett

LSU Master's Theses

Historians typically agree that reconciliation between the white North and South took place between the period of 1898 (Spanish-American War) and 1913 (before World War I). To test this hypothesis and identify when reconciliation took place in Baton Rouge, Louisiana, I will use the burial of R. L. Pruyn in the Baton Rouge National Cemetery. Pruyn served as a U.S. soldier during the Mexican War and a Confederate soldier during the Civil War. Anthropologists have studied rituals, beliefs, and practices associated with death since early in the discipline. Archaeologists, in particular, have focused on this aspect of culture, in large …
