The Relationship Between Mania And Feeding/Mealtime Behavior Problems Among Persons With Intellectual Disability, Rinita Laud Jan 2006

The Relationship Between Mania And Feeding/Mealtime Behavior Problems Among Persons With Intellectual Disability, Rinita Laud

LSU Doctoral Dissertations

This study represents the first to assess whether a relationship between mania and feeding/mealtime behavior problems exists in individuals with ID. Participants were compared across three groups (manic, non-manic psychiatrically impaired, and controls) on subscales and items of the Screening Tool for fEeding Problems (STEP). An attempt was made to assess for differences in problematic feeding behavior. Individuals in the manic group exhibited clinically significant symptoms of mania (n = 18), those in the non-manic psychiatrically impaired group exhibited symptoms of psychopathology other than mania (n = 18), and those in the control group did not exhibit symptoms of mania …

Effects Of Smoking Cessation And Female Sex Hormones On Food Intake In Postmenopausal Women, Megan Ranae Apperson Jan 2006

Effects Of Smoking Cessation And Female Sex Hormones On Food Intake In Postmenopausal Women, Megan Ranae Apperson

LSU Master's Theses

Following smoking cessation, individuals increase their food intake. Women experience greater postcessation hyperphagia than men, and older women may increase their food intake more than younger women. Some research has suggested that postcessation increases in food intake may be macronutrient specific. However, previous investigations of macronutrient specific changes in food intake following smoking cessation have had significant methodological problems. The current study assessed changes in total food intake and macronutrient selection using the Macronutrient Self-Selection Paradigm (MSSP), a direct, laboratory based measure of food intake that is valid and reliable with respect to macronutrient intake. Fifty-five postmenopausal females completed the …

Target Audiences And Communication Channels Of Lighten Up Programs In The United States, Nancy Leah Borden Jan 2006

Target Audiences And Communication Channels Of Lighten Up Programs In The United States, Nancy Leah Borden

LSU Master's Theses

Several Lighten Up programs around the United States were qualitatively studied in efforts to determine their target audiences and the communication channels used to reach these audiences. To guide this study, principles from the social marketing framework and the diffusion of innovations theory were applied. Several Lighten Up program executive directors and other high-ranking individuals in charge of the programs were interviewed in-depth to answer questions pertaining to target audiences and communication channels. Inductive data analysis illustrated that programs did not segment their target audiences, that more programs depended on interpersonal and group communication than mass communication, and finally, that …

Phytoremediation Of A High Phosphorus Soil By Summer And Winter Hay Harvest, Veronica A. Ryan Jan 2006

Phytoremediation Of A High Phosphorus Soil By Summer And Winter Hay Harvest, Veronica A. Ryan

LSU Master's Theses

Phosphorus (P) loading into surface water from runoff and subsurface flow leaving soils subjected to long-term applications of poultry litter (PL) will degrade water quality. A practical way to reduce such loading is to remove soil P through plant uptake and harvest removal. The primary field study presented here examined the effectiveness of hay harvest utilizing a double-cropped system - perennial warm-season forage grass, common bermudagrass (CB; Cynodon dactylon (L.) Pers.), overseeded with annual ryegrass (ARG; Lolium multiflorum Lam.), a cool-season forage, in reducing soil P from a Ruston fine-sandy loam impacted by PL amendments. A secondary field study similarly …

Modulation Of Yeast Genome Expression In Response To Defective Rna Polymerase Iii-Dependent Transcription, Christine Conesa, Roberta Ruotolo, Pascal Soularue, Tiffany A. Simms, David Donze, André Sentenac, Giorgio Dieci Oct 2005

Modulation Of Yeast Genome Expression In Response To Defective Rna Polymerase Iii-Dependent Transcription, Christine Conesa, Roberta Ruotolo, Pascal Soularue, Tiffany A. Simms, David Donze, André Sentenac, Giorgio Dieci

Faculty Publications

We used genome-wide expression analysis in Saccharomyces cerevisiae to explore whether and how the expression of protein-coding, RNA polymerase (Pol) II-transcribed genes is influenced by a decrease in RNA Pol III-dependent transcription. The Pol II transcriptome was characterized in four thermosensitive, slow-growth mutants affected in different components of the RNA Pol III transcription machinery. Unexpectedly, we found only a modest correlation between altered expression of Pol II-transcribed genes and their proximity to class III genes, a result also confirmed by the analysis of single tRNA gene deletants. Instead, the transcriptome of all of the four mutants was characterized by increased …

Analysis Of The Distribution And Diversity In Recent Hawaiian Volcanic Deposits Of A Putative Carbon Monoxide Dehydrogenase Large Subunit Gene, Kari E. Dunfield, Gary M. King Sep 2005

Analysis Of The Distribution And Diversity In Recent Hawaiian Volcanic Deposits Of A Putative Carbon Monoxide Dehydrogenase Large Subunit Gene, Kari E. Dunfield, Gary M. King

Faculty Publications

A putative carbon monoxide dehydrogenase large subunit gene (BMS putative coxL) was amplified from genomic DNA extracts of four recent (42-300 year old) Hawaiian volcanic deposits by polymerase chain reaction (PCR). Sequence databases derived from clone libraries constructed using PCR products were analysed phylogenetically and statistically. These analyses indicated that each of the deposits supported distinct BMS putative coxL gene assemblages. Statistical analyses also showed that the youngest deposit (42 years old) contained the least diverse sequences (P < 0.05), but that diversity did not vary significantly among three older deposits with ages from about 108-300 years. Although diversity indices did not vary among the older deposits, mismatch analyses suggested population structures increased in complexity with increasing deposit age. At each of the sites, most of the clone sequences appeared to originate from Proteobacteria not currently represented in culture or recognized as CO oxidizers. © 2005 Society for Applied Microbiology and Blackwell Publishing Ltd.

The Regulation Of Fatty Acid Synthase By Stat5a, Jessica C. Hogan, Jacqueline M. Stephens Jul 2005

The Regulation Of Fatty Acid Synthase By Stat5a, Jessica C. Hogan, Jacqueline M. Stephens

Faculty Publications

Growth hormone (GH) diminishes adipose tissue mass in vivo and decreases expression and activity of fatty acid synthase (FAS) in adipocytes. GH and prolactin (PRL) are potent activators of STAT5 and exert adipogenic and antiadipogenic effects in adipocytes. In this study, we demonstrate that GH and PRL decrease the mRNA and protein levels of FAS in 3T3-L1 adipocytes. We present evidence that indicates that FAS is repressed at the level of transcription. In addition, PRL responsiveness was shown to exist between -1,594 and -700 of the rat FAS promoter. Moreover, responsiveness to PRL was abolished with mutation of a site …

Ethnicity, Education, And Blood Pressure In Cuba, Pedro Ordunez, Jose Luis Bernal Munoz, Alfredo Espinosa-Brito, Luis Carlos Silva, Richard S. Cooper

Faculty Publications

The causes of variation in hypertension risk by ethnicity and educational level are not well understood. To gain further insight into this issue in a nonindustrialized country, a population-based sample of 1,667 persons aged 15-74 years was recruited in Cienfuegos, Cuba. In this 2001-2002 study, interviewers classified 29% of participants as Black or mulatto and 71% as White. Educational attainment was stratified at the median number of school years. Compared with White women, non-White women had higher blood pressures (3.0/1.7, systolic blood pressure/ diastolic blood pressure) and a higher prevalence of hypertension (24%, 95% confidence interval: 20, 28 vs. 15%, …

Effects Of Leukemia Inhibitory Factor On 3t3-L1 Adipocytes, Jessica C. Hogan, Jacqueline M. Stephens Jun 2005

Effects Of Leukemia Inhibitory Factor On 3t3-L1 Adipocytes, Jessica C. Hogan, Jacqueline M. Stephens

Faculty Publications

Leukemia inhibitory factor (LIF) is a member of the gp130 cytokine family and signals through the receptor complex of gp130 and the LIF receptor (LIFR) to activate the JAK/STAT signaling cascade. Since LIF activates STATs 1 and 3 in adipocytes, we examined the effects of LIF on 3T3-L1 adipocytes. Our studies clearly demonstrate that LIF treatment had minimal effects on adipocyte differentiation as judged by marker gene expression, but did inhibit triacylglyceride (TAG) accumulation during adipogenesis. Acute treatment with LIF resulted in increased expression of suppressors of cytokine signaling-3 (SOCS3) and CCAAT/enhancer-binding protein-δ (C/EBPδ) mRNA in 3T3-L1 adipocytes. Moreover, the …

Background: The consistent finding of higher prevalence of hypertension in US blacks compared to whites has led to speculation that African-origin populations are particularly susceptible to this condition. Large surveys now provide new information on this issue. Methods: Using a standardized analysis strategy we examined prevalence estimates for 8 white and 3 black populations (N = 85,000 participants). Results: The range in hypertension prevalence was from 27 to 55% for whites and 14 to 44% for blacks. Conclusions: These data demonstrate that not only is there a wide variation in hypertension prevalence among both racial groups, the rates among blacks …

Formosan Subterranean Termite (Isoptera: Rhinotermitidae) Soldiers Regulate Juvenile Hormone Levels And Caste Differentiation In Workers, Lixin Mao, Gregg Henderson, Yuxiu Liu, Roger A. Laine

Faculty Publications

A caste structure is maintained in termite societies and juvenile hormone (JH) is generally regarded as the most important regulator in these termite colonies. Here, we demonstrate that the soldier caste regulates JH in workers of Coptotermes formosanus Shiraki. Worker termites (80-100 individuals) were placed in petri dishes with 0, 5, 10, or 20% soldiers. JH III titers of groups of these workers were monitored at 14, 28, 42, and 56 d. Any changes in soldier caste proportions also were noted at each sample date. On the first sample date, the JH levels in workers were similar among treatments with …

Association Between Chronic Kidney Disease And Coronary Artery Calcification: The Dallas Heart Study, Holly Kramer, Robert Toto, Ronald Peshock, Richard Cooper, Ronald Victor

Faculty Publications

The hypothesis that chronic kidney disease (CKD) is associated with increased coronary artery calcification (CAC) was tested using data from the Dallas Heart Study, a representative sample of Dallas County residents aged 30 to 65 yr. CKD was defined as presence of microalbuminuria and GFR ≥ 60 ml/min per 1.73 m2 (stage 1 to 2), or GFR < 60 ml/min per 1.73 m 2 (stage 3 to 5), excluding end-stage kidney disease. Logistic regression was used to examine the association between stages of CKD and CAC scores > 10, > 100, and > 400 versus scores ≤ 10 compared with no CKD while adjusting for covariates. Analyses were repeated after stratifying by presence of diabetes. The mean age was 43.9 yr, and hypertension and diabetes were noted in 31.0 and 9.8%, respectively. No …

Storage Stability Of Lutein During Ripening Of Cheddar Cheese, S. T. Jones, K. J. Aryana, J. N. Losso

Faculty Publications

Lutein (3,3′-dihydroxy-α-carotene) has been identified as a dietary factor that can delay the onset of age-related macular degeneration (AMD). However, available food sources of lutein contain only modest amounts of the carotenoid. Food fortification with lutein extract has been identified as a low-budget approach to prevent the onset or progression of AMD. The objectives of this study were to 1) incorporate various amounts of lutein into Cheddar cheese; 2) examine the color, pH, microbiological, and sensory characteristics of the Cheddar cheese during storage; and 3) analyze the stability of lutein during the cheese maturation process. Lutein extracted from corn was …

Secular Change In The Skull Between American Blacks And Whites, Nicole Danielle Truesdell Jan 2005

Secular Change In The Skull Between American Blacks And Whites, Nicole Danielle Truesdell

LSU Master's Theses

Biologically, discernable differences exist between and within populations based on environmental and genetic factors. Understanding these differences is necessary in forensic anthropology as biological ancestry is asked of forensic anthropologists when assessing an individual’s biological profile. In order to make this assessment, secular changes in population dynamics need to be tracked. The purpose of this research is to examine nonmetric racial characteristics in the skull between American blacks and whites. This study used twelve nonmetric traits as criteria on two different temporal groups from collections at the Smithsonian Institution (N=408) and the University of Tennessee, Knoxville (N=218).

Reproductive Characteristics Of High Body Condition Mares With High Versus Low Leptin Concentrations, Cara A. Waller Jan 2005

Reproductive Characteristics Of High Body Condition Mares With High Versus Low Leptin Concentrations, Cara A. Waller

LSU Master's Theses

Two experiments were performed to discover what, if any, reproductive differences exist in high body condition (BCS) mares with varying concentrations of leptin. Previous research showed that mares with high body condition scores can have a range of leptin levels, from very low (<5 ng/mL) to very high (>10 ng/mL). Earlier results indicated that most mares with high body condition scores maintain estrous cycles or show significant follicular activity during the winter. Among these high BCS mares, about 30% of them exhibit hyperleptinemia and hyperinsulinemia. The first experiment was designed to compare the reproductive characteristics of high BCS mares with high versus low leptin …
