Health In Cuba, Richard S. Cooper, Joan F. Kennelly, Pedro Orduñez-Garcia Aug 2006

Health In Cuba, Richard S. Cooper, Joan F. Kennelly, Pedro Orduñez-Garcia

Faculty Publications

The poorer countries of the world continue to struggle with an enormous health burden from diseases that we have long had the capacity to eliminate. Similarly, the health systems of some countries, rich and poor alike, are fragmented and inefficient, leaving many population groups underserved and often without health care access entirely. Cuba represents an important alternative example where modest infrastructure investments combined with a well-developed public health strategy have generated health status measures comparable with those of industrialized countries. Areas of success include control of infectious diseases, reduction in infant mortality, establishment of a research and biotechnology industry, and …

Positive Association Between Resting Energy Expenditure And Weight Gain In A Lean Adult Population, Amy Luke, Ramon Durazo-Arvizu, Guichan Cao, Adebowale Adeyemo, Bamidele Tayo, Richard Cooper May 2006

Positive Association Between Resting Energy Expenditure And Weight Gain In A Lean Adult Population, Amy Luke, Ramon Durazo-Arvizu, Guichan Cao, Adebowale Adeyemo, Bamidele Tayo, Richard Cooper

Faculty Publications

Background: Weight gain in adulthood is common, from modest gains in developing countries to substantial increases in Western societies. Evidence of the importance of energy expenditure in adult weight change has been limited to studies conducted in Pima Indians, in whom resting energy expenditure (REE) was found to be inversely associated with weight gain. Objective: The aim was to determine whether REE was predictive of weight change in lean Nigerian adults. Design: Weight was measured in 744 adults on 2-4 occasions over 5.5 y. REE was measured in the second follow-up examination. Sex-specific, mixed-effects models with REE, fat-free mass, and …

Antagonisms, Mutualisms And Commensalisms Affect Outbreak Dynamics Of The Southern Pine Beetle, Richard W. Hofstetter, James T. Cronin, Kier D. Klepzig, John C. Moser, Matthew P. Ayres Apr 2006

Antagonisms, Mutualisms And Commensalisms Affect Outbreak Dynamics Of The Southern Pine Beetle, Richard W. Hofstetter, James T. Cronin, Kier D. Klepzig, John C. Moser, Matthew P. Ayres

Faculty Publications

Feedback from community interactions involving mutualisms are a rarely explored mechanism for generating complex population dynamics. We examined the effects of two linked mutualisms on the population dynamics of a beetle that exhibits outbreak dynamics. One mutualism involves an obligate association between the bark beetle, Dendroctonus frontalis and two mycangial fungi. The second mutualism involves Tarsonemus mites that are phoretic on D. frontalis ("commensal"), and a blue-staining fungus, Ophiostoma minus. The presence of O. minus reduces beetle larval survival ("antagonistic") by outcompeting beetle-mutualistic fungi within trees yet supports mite populations by acting as a nutritional mutualist. These linked interactions potentially …

Faculty Publications

Objective: Peptide YY (PYY) and glucagon-like peptide-1 are important in the control of energy homeostasis and are both secreted from the gut in response to ingested nutrients. However, more studies are needed on nutrient regulation of their gene expression patterns in specific areas of the gut. This study detailed PYY and proglucagon (the gene that encodes glucagon-like peptide-1) gene expression patterns and regulation in the gut. We further examined the regulation of PYY and proglucagon mRNA by a diet containing fermentation- resistant starch (in vivo) and butyrate (in vitro). Research Methods and Procedures: Quantitative real time reverse transcriptase-polymerase chain reaction …

Epithelial Sodium Channel Allele T594m Is Not Associated With Blood Pressure Or Blood Pressure Response To Amiloride, John M. Hollier, Dan F. Martin, Darin M. Bell, Jia Ling Li, Mike G. Chirachanchai, Dileep V. Menon, David Leonard, Xiaodong Wu, Richard S. Cooper, Colin Mckenzie, Ronald G. Victor, Richard J. Auchus

Faculty Publications

The T594M allele of the epithelial sodium channel β-subunit has been proposed as a gain-of-function mutation leading to salt-sensitive hypertension in blacks that is particularly responsive to the specific sodium channel antagonist amiloride. However, the positive associations derive from small convenience samples, and the amiloride challenge study lacked a control group. We determined whether the T594M allele was associated with hypertension and blood pressure (BP) response to amiloride in 2 well-characterized random population samples including 3137 Dallas County subjects and 1666 Jamaican blacks. In multivariate models, the T594M allele was not predictive of systolic BP (adjusted odds ratio for hypertension …

Interfacing Capillary Gel Microfluidic Chips With Infrared Laser Desorption Mass Spectrometry, Yichuan Xu, Mark W. Little, Kermit K. Murray

Faculty Publications

We report on the fabrication and performance of a gel microfluidic chip interfaced to laser desorption/ionization (LDI) mass spectrometry with a time-of-flight mass analyzer. The chip was fabricated from poly(methylmethacrylate) with a poly(dimethyl siloxane) cover. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis was performed in the channel of the microfluidic chip. After electrophoresis, the cover was removed and either the PDMS chip or the PMMA cover was mounted in a modified MALDI ion source for analysis. Ions were formed by irradiating the channel with 2.95 μm radiation from a pulsed optical parametric oscillator (OPO), which is coincident with IR absorption by N-H …

Coprophagy In A Cave-Adapted Salamander; The Importance Of Bat Guano Examined Through Nutritional And Stable Isotope Analyses, Danté B. Fenolio, G. O. Graening, Bret A. Collier, Jim F. Stout

Faculty Publications

During a two year population ecology study in a cave environment, 15 Eurycea (=Typhlotriton) spelaea were observed ingesting bat guano. Furthermore, E. spelaea capture numbers increased significantly during the time that grey bats (Myotis grisescens) deposited fresh guano. We investigated the hypothesis that this behaviour was not incidental to the capture of invertebrate prey, but a diet switch to an energy-rich detritus in an oligotrophic environment. Stable isotope assays determined that guano may be assimilated into salamander muscle tissue, and nutritional analyses revealed that guano is a comparable food source to potential invertebrate prey items. This is the first report …

The Prp19 U-Box Crystal Structure Suggests A Common Dimeric Architecture For A Class Of Oligomeric E3 Ubiquitin Ligases, Craig W. Vander Kooi, Melanie D. Ohi, Joshua A. Rosenberg, Michael L. Oldham, Marcia E. Newcomer, Kathleen L. Gould, Walter J. Chazin

Faculty Publications

Prp19 is an essential splicing factor and a member of the U-box family of E3 ubiquitin ligases. Prp19 forms a tetramer via a central coiled-coil domain. Here, we show the U-box domain of Prp19 exists as a dimer within the context of the Prp19 tetramer. A high-resolution structure of the homodimeric state of the Prp19 U-box was determined by X-ray crystallography. Mutation of the U-box dimer interface abrogates U-box dimer formation and is lethal in vivo. The structure of the U-box dimer enables construction of a complete model of Prp19 providing insights into how the tetrameric protein functions as an …

Effect Of Scraping Frequency In A Freestall Barn On Volatile Nitrogen Loss From Dairy Manure, V. R. Moreira, L. D. Satter Jan 2006

Effect Of Scraping Frequency In A Freestall Barn On Volatile Nitrogen Loss From Dairy Manure, V. R. Moreira, L. D. Satter

Faculty Publications

The objective of this investigation was to evaluate the effect of scraping frequency (2× vs. 6× daily) on N volatilization from manure on the floor of a dairy free-stall barn. Three trials (crossover design) were conducted in the summers of 2001 and 2002, and in the winter of 2003. Nitrogen volatilization was estimated from the change in the N:P ratio in excreta at the time of excretion to the time when manure was scraped from the barn. Total N loss was considered a maximum estimate of NH3-N loss, because small amounts of nonammonia N may be volatilized. Nitrogen was determined …

A Spectrum Of Pcsk9 Alleles Contributes To Plasma Levels Of Low-Density Lipoprotein Cholesterol, Ingrid K. Kotowski, Alexander Pertsemlidis, Amy Luke, Richard S. Cooper, Gloria L. Vega, Jonathan C. Cohen, Helen H. Hobbs

Faculty Publications

Selected missense mutations in the proprotein convertase subtilisin/kexin type 9 serine protease gene (PCSK9) cause autosomal dominant hypercholesterolemia, whereas nonsense mutations in the same gene are associated with low plasma levels of low-density lipoprotein cholesterol (LDL-C). Here, DNA sequencing and chip-based oligonucleotide hybridization were used to determine whether other sequence variations in PCSK9 contribute to differences in LDL-C levels. The coding regions of PCSK9 were sequenced in the blacks and whites from the Dallas Heart Study (n = 3,543) who had the lowest (percentile) and highest (>95 th percentile) plasma levels of LDL-C. Of the 17 missense variants identified, …

Evaluation Of Bovine Spermatid Sex Ratio By Fluorescent In Situ Hybridization, Michael Alan Stout

LSU Master's Theses

The objective of this study was to use fluorescent in situ hybridization (FISH) to determine if a skew in the sex ratio was present at the level of the bovine round spermatid. Paraffin embedded bovine testicular tissue obtained from biopsies were used to perform FISH, and the seminiferous tubules were examined. Our findings show that the skew does exist within the round spermatids. Analysis of variance on X- and Y-chromosome bearing round spermatids as affected by sex, slide, picture set, and tubule was performed. Sex showed that the variation in round spermatid sex ratio differed between slides (P = 0.0001). …

Created Environments Voluntarily Colonized By Spartina Alterniflora In Coastal Louisiana, Han Xu Jan 2006

Created Environments Voluntarily Colonized By Spartina Alterniflora In Coastal Louisiana, Han Xu

LSU Master's Theses

The coastal wetlands play a central role in maintaining productivity of the Gulf of Mexico while protecting coastal regions during severe storms. To help offset the loss of coastal marsh, there is growing interest in the beneficial use of dredge spoil for reconstruction of eroded areas. Hydraulic dredges are routinely employed to maintain navigation and the unconsolidated sediments can be pumped considerable distances to create gently sloping wetland areas. Some areas of these reconstructed wetlands are rapidly colonized by Spartina alterniflora, the dominant vegetative species in saline areas under tidal influence. Some areas, however, fail to colonize despite favorable positions …

Spaced-Retrieval Effects On Memory For Scenes In Older Adults With Probable Alzheimer's Disease, Emily Olinde Jan 2006

Spaced-Retrieval Effects On Memory For Scenes In Older Adults With Probable Alzheimer's Disease, Emily Olinde

LSU Master's Theses

Previous studies have found the spaced-retrieval memory intervention technique to be successful in training people with probable Alzheimer’s disease (AD) to learn new, simple associations. In the present study, we expanded on these previous findings by training eight participants with probable AD to learn the names and pictures of countries via spaced retrieval. We demonstrated the flexibility of the technique, gave insight as to the effects of distracters on the spaced-retrieval training performance, and demonstrated the memorial effects of adding pictorial support to the text.

From The Top Down And The Bottom Up: The Contemporary Practice And Choice Of Midwifery In Louisiana, Michelle M. Wydra Jan 2006

From The Top Down And The Bottom Up: The Contemporary Practice And Choice Of Midwifery In Louisiana, Michelle M. Wydra

LSU Master's Theses

This research examines the contemporary practice of midwifery in Louisiana, a state that very early on had progressive legislation, yet remains a tough place for a midwife to practice. What, then, are the social forces that affect the ability to practice midwifery in Louisiana? I try to answer that question by examining the narratives of midwives and their clients, and evaluating the options these women have access to in this state. The narratives provide opportunities to observe the authoritarian knowledge of biomedicine in our society, and apply Foucault’s theory of power/knowledge. I describe that although Louisiana’s regulation of the practice …

Strain To Strain Differences In The Growth, Survival And Adaptation Of Vibrio Vulnificus And Vibrio Parahaemolyticus In Broth, Veronica Elaine Burnham

LSU Master's Theses

Vibrio vulnificus and Vibrio parahaemolyticus are natural inhabitants of estuarine environments of the Gulf of Mexico. V. vulnificus is the leading cause of death, while V. parahaemolyticus is a leading cause of foodborne gastroenteritis from the consumption of seafood in the United States. Refrigeration is commonly used as a preservation method to control the growth of microorganisms in food. The ability of some microorganisms to adapt, as a survival response when exposed to a downshift in temperature, could compromised efforts to use low temperature storage to reduce the risk of foodborne illnesses. Limited research is available on the growth characteristics …

Quality Characterization Of Cholesterol-Free Mayonnaise-Type Spreads Containing Rice Bran Oil, Karen Melissa Garcia

LSU Master's Theses

Traditional mayonnaise is manufactured with soybean oil (SBO) and egg-yolk containing ingredients. About 1/4 of American consumers have some forms of cardiovascular disease, accounting for >40% of all deaths in USA. Rice bran oil (RBO), a healthy lipid source, has cholesterol-lowering effects, and could be used to replace SBO in mayonnaise preparation. To take advantage of the health benefits associated with RBO, food products containing RBO need to be developed and characterized. Cholesterol-free mayonnaise-type spreads containing RBO were developed using a constrained mixture design. Two studies were performed to determine sensory attributes driving acceptance and purchase intent and to optimize …
