Changes In Bone Mineral Density In Middle-Age Women According To Physical Activity Volume, Intensity, And Cardiorespiratory Fitness: A Six-Year Prospective Study, Neil R. Nokes

Theses and Dissertations

This study was conducted to determine if physical activity and cardiorespiratory fitness (CRF) at baseline influence the likelihood of gaining bone mineral density (BMD) at the hip and lumbar spine over 6 years. Another aim was to ascertain the effect of several potential confounding factors. In a prospective study of 244 women (baseline age range 35-45 years), physical activity volume (PAv) and intensity (PAi) were measured using accelerometers at baseline. CRF indexed by VO2max was estimated using a graded, maximal treadmill test at baseline. BMD was measured using DEXA. Risk ratios were used to show the likelihood of BMD gains …

Towards A Universal Ultra-Thin Fluorinated Diamond-Like Carbon Coating For Nanoimprint Lithography Imprinters, Ryan Winfield Fillman

Theses and Dissertations

Nanoimprint lithography (NIL) has proven to achieve arbitrary, nanoscale features, over large areas, without the use of costly step-and-repeat UV lithography tools. The fidelity of the imprinted pattern depends on the elimination of the adhesion between the imprinted polymer and the imprinter upon withdrawal of the imprinter. The plasma deposition of a layer of fluorinated diamond-like carbon (F-DLC) has proven to be a successful anti-adhesion layer but in the past has required an entire diamond-like carbon (DLC) substrate. The requirement that the imprinter be made of DLC limits the imprinter processing and can limit the capabilities of NIL. DLC films …

Flagellum-Mediated Biofilm Defense Mechanisms Of Pseudomonas Aeruginosa Against Host-Derived Lactoferrin, Jeff G. Leid, Mathias Kerr, Candice Selgado, Chelsa Johnson, Gabriel Moreno, Alyssa Smith, Mark E. Shirtliff, Georg A. O'Toole, Emily K. Cope

Dartmouth Scholarship

Chronic infection with the gram-negative organism Pseudomonas aeruginosa is a leading cause of morbidity and mortality in human patients, despite high doses of antibiotics used to treat the various diseases this organism causes. These infections are chronic because P. aeruginosa readily forms biofilms, which are inherently resistant to antibiotics as well as the host's immune system. Our laboratory has been investigating specific mutations in P. aeruginosa that regulate biofilm bacterial susceptibility to the host. To continue our investigation of the role of genetics in bacterial biofilm host resistance, we examined P. aeruginosa biofilms that lack the flgK gene. This mutant …

Thermal Tolerance Of The Coffee Berry Borer Hypothenemus Hampei: Predictions Of Climate Change Impact On A Tropical Insect Pest, Juliana Jaramillo, Adenirin Chabi-Olaye, Charles Kamonjo, Alvaro Jaramillo, Fernando E. Vega, Hans Michael Poehling, Christian Borgemeister

All Peer-Reviewed Publications

Coffee is predicted to be severely affected by climate change. We determined the thermal tolerance of the coffee berry borer , Hypothenemus hampei, the most devastating pest of coffee worldwide, and make inferences on the possible effects of climate change using climatic data from Colombia, Kenya, Tanzania, and Ethiopia. For this, the effect of eight temperature regimes (15, 20, 23, 25, 27, 30, 33 and 35°C) on the bionomics of H. hampei was studied. Successful egg to adult development occurred between 20-30°C. Using linear regression and a modified Logan model, the lower and upper thresholds for development were estimated at …

The Effects Of Fluorescent Tracking Powder On Oxygen Consumption In Salamanders Using Either Cutaneous Or Bimodal Respiration, Sarah A. Orlofske, Kristine L. Grayson, William A. Hopkins

Biology Faculty Publications

Fluorescent powder is gaining attention as an effective method for tracking terrestrial amphibian movements, particularly for species that are too small for conventional tracking equipment. The technique requires coating portions of an animal with fluorescent powder, releasing the animal, and following the trail of powder as it is progressively lost during movement. Recent studies have shown that fluorescent powder has no negative effects on survival or growth. However, a substance that coats the skin, a major respiratory organ in most amphibians, may have sublethal effects on performance and consequently behavior. We tested the effect of fluorescent powder application on the …

Mutagenesis And Spectroscopic Studies Of Mycobacterium Tuberculosis Sterol 14alpha Demethylase., Anuja R. Modi

Theses and Dissertations

P450s are heme containing enzymes which affect oxidation of substrates via catalytic intermediates having transient lifetimes. These oxidative catalytic intermediates are formed by a sequential interplay of electrons and protons at the active site of the enzyme bearing molecular dioxygen. The proton transfer to the active site from bulk solvent is coordinated by an “acid-alcohol” pair of active site residues which are conserved in all P450s. Sterol 14α-demethylases (CYP51) are P450 enzymes which catalyze oxidative deformylation of lanosterol in the cholesterol/ergosterol biosynthetic pathway. Both cholesterol and ergosterol are important regulators of membrane fluidity. CYP51 differs from other P450s in that …

A Sensitivity Matrix Methodology For Inverse Problem Formulation, Ariel Cintron-Arias, H. T. Banks, Alex Capaldi, Alun L. Lloyd

Mathematics and Computer Science Faculty Publications

We propose an algorithm to select parameter subset combinations that can be estimated using an ordinary least-squares (OLS) inverse problem formulation with a given data set. First, the algorithm selects the parameter combinations that correspond to sensitivity matrices with full rank. Second, the algorithm involves uncertainty quantification by using the inverse of the Fisher Information Matrix. Nominal values of parameters are used to construct synthetic data sets, and explore the effects of removing certain parameters from those to be estimated using OLS procedures. We quantify these effects in a score for a vector parameter defined using the norm of the …

Weight-Related Effects On Disease Progression In The Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis Trial, Herbert L. Bonkovsky

UCHC Articles - Research

BACKGROUND & AIMS With the limited efficacy of current therapy for chronic hepatitis C, modifiable risk factors for liver disease progression are important to identify. Because obesity is associated with liver disease, we examined the effects of weight-related conditions on disease outcomes in the Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis (HALT-C) trial. METHODS Of 1050 patients, 985 could be evaluated for predefined progression of liver disease not related to hepatocellular carcinoma. Clinical outcomes were determined over 3.5 years for all patients and progression to cirrhosis on protocol biopsy among patients who had bridging fibrosis (56.5% of cohort) at entry. …

A Decomposition Of The Pure Parsimony Problem, Allen Holder, Thomas M. Langley

Mathematical Sciences Technical Reports (MSTR)

We partially order a collection of genotypes so that we can represent the problem of inferring the least number of haplotypes in terms of substructures we call g-lattices. This representation allows us to prove that if the genotypes partition into chains with certain structure, then the NP-Hard problem can be solved efficiently. Even without the specified structure, the decomposition shows how to separate the underlying integer programming model into smaller models.

2009 Winter Wheat Variety Yield Results And Planting Tips, John Rickertsen, Thandiwe Nleya, Bill Berzonsky, R. G. Hall

SDSU Extension Extra Archives

2009 turned out to be mixed bag for winter wheat production in South Dakota. Some areas in the west and central part of the state did not get much rain in the fall. Dry conditions in these areas delayed germination, setting back seedling development and resulting in thin stands. The Wall, Martin, and Pierre locations were within this dry region. At Martin, a combination of thin stands and downy brome weed pressure adversely affected plant development and yield. Yield results from Martin are not included in this report. Most locations in the eastern part of the state had adequate moisture …

Retention, Social Promotion, And Dropout Rates In Mississippi, Jennifer Jo Woodruff

Dissertations

There has been much research in the past two decades about the dropout problem in America. Dropout rates have become a focal point for all public schools in the nation largely due to components of the No Child Left Behind Act and the Dropout Prevention Act that associate monetary rewards to schools that raise the graduation completion rates to 90%. The dropout rates for the United States rank the educational system 17th for graduation completion rates among developed countries. Mississippi has repeatedly earned the title of low-ranking among all states in the nation.

Preliminary Phytochemical And Antimicrobial Properties Of Pueraria Tuberosa (Willd.) Dc: A Potential Medicinal Plant, K. Venkata Ratnam, R. R. Venkata Raju

Ethnobotanical Leaflets

In vitro antimicrobial and chemical properties of petroleum ether, ethyl acetate and ethanol extracts of Pueraria tuberosa were evaluated. Among the test samples ethyl acetate extract showed pronounced antimicrobial activity, while ethanol extract exhibited the least activity and petroleum ether extract failed to inhibit the test pathogens. Preliminary phytochemical analysis of extracts revealed the presence of antimicrobial compounds such as alkaloids, flavonoids, coumarins, volatile oils and glycosides. The phenolic compounds and flavonoids were abundant in ethyl acetate extract when compared to other extracts. The broad spectrum of antimicrobial activity of ethyl acetate extract may be due to the presence of …

Shopping With Elephants: Coming To Terms With Nepotism In The Retail Space, Knowledge@Smu

Knowledge@SMU

Nepotism, favouritism and discrimination: issues that exist not only in business and politics, but also, in shopping malls! Research has shown that customers will likely receive benefits and superior service when they demonstrate a common “bond” with the people who serve them. Perks include free products, upgrades, queue-jumps and other value-adds, such as staff recommendations and extra attentive service. While such “allowances” create wonderful retail experiences for customers who receive it, is it fair for those who don’t?

Bridging Functional Genomics And Toxicogenomics Through Dna Microarrays In A Fish Model, Shuzhao Li

Dissertations

In a case study of finding gene expression signatures for environmental stressors in Cyprinodon variegatus, this dissertation examines several important issues of applying DNA microarray technology to fish toxicogenomics. The most relevant disciplines, fish toxicogenomics and computational systems biology are reviewed in Chapter 1. Chapter 2 reviews major aspects of DNA microarray technology.

On DNA microarrays, even for probes that target the same transcript, large variations are seen in the probe signals. These variations are partly dependent and partly independent on probe sequences. Chapter 3 estimates the sequence independent variation by combining experimental and computational approaches. Chapter 4 and …

Characterization Of Γ-Butyrolactone Autoregulatory Signaling Gene Homologs In The Angucyclinone Polyketide Ws5995b Producer Streptomyces Acidiscabies, Frank G. Healy, Kevin P. Eaton, Prajit Limsirichai, Joel F. Aldrich, Alaina K. Plowman, Russell R. King

Biology Faculty Research

Organisms belonging to the genus Streptomyces produce numerous important secondary metabolites and undergo a sophisticated morphological differentiation program. In many instances these processes are under the control of gamma-butyrolactone (GBL) autoregulatory systems. Streptomyces acidiscabies strain 84.104 produces the secondary metabolite aromatic angucyclinone polyketide WS5995B. In order to explore the role of GBL regulatory circuitry in WS5995B production and morphogenesis in S. acidiscabies, a gene cluster encoding GBL autoregulatory signaling homologs was identified and characterized. Two GBL receptor homologs, sabR and sabS, were found flanking a GBL synthase homolog sabA. Strains carrying mutations in sabS produced elevated levels …

A Survey Of Drought Impacts And Mitigation Planning In Kentucky, Crystal Jane Bergman

Masters Theses & Specialist Projects

Drought is a well-known and costly climate-related natural hazard. Unlike other climate-related natural hazards, droughts are usually long in duration and may cover a large region, the physical boundaries of areas affected by drought are sometimes arbitrary, and the impacts are sometimes difficult to identify. Climate records since 1895 show that drought has occurred periodically in Kentucky. The drought of 2007 was the most recent drought to affect Kentucky and is the primary focus of this research. The purpose of this research is to identify impacts of drought and potential vulnerabilities to various drought impact sectors in Kentucky so that …

Feral Animals And The Restoration Of Nature, Roger J.H. King

Between the Species

Projects to restore nature inevitably disrupt the plants and animals that inhabit the land to be restored. This essay addresses the significance of feral animals. Can feral animals remain in a restored nature? I argue that an answer depends on what we mean by nature and restoration. I present several different conceptions of nature and discuss what their differences mean for the goals of restoration. While the presence of feral animals is not compatible with the dualist conception of nature as that which is untouched by humans, other conceptions are more accommodating. Restoration to a benchmark of nature prior to …
