Food For Early Succession Birds: Relationships Among Arthropods, Shrub Vegetation, And Soil, Richard N. Conner, Daniel Saenz, Brent Burt

Faculty Publications

During spring and early summer, shrub- and herbaceous-level vegetation provides nesting and foraging habitat for many shrub-habitat birds. We examined relationships among arthropod biomass and abundance, foliage leaf surface area and weight, vegetation ground cover, soil characteristics, relative humidity, and temperature to evaluate what factors may influence arthropod food resources for birds. Relative humidity was inversely associated with arthropod biomass; as humidity increased biomass decreased (r = -0.44, P = 0.004). We failed to detect any relationships between deciduous foliage (surface area and weight) and arthropod biomass or abundance. However, both arthropod abundance (r = 0.30, P = 0.06) and …

Effects Of Flooding Regime, Mycorrhizal Inoculation And Seddling Treatment Type On First-Year Survival Of Nuttall Oak (Quercus Nuttallii Palmer), Hans Michael Williams, Virginia Burkett

Faculty Publications

Three different types of Nuttall oak ( Quercus nuttallii Palmer) seedlings were planted on floodprone, former cropland in Mississippi, Louisiana, and Texas. The three types of 1+0 seedlings planted at each site in January and February of 1995 were bareroot seedlings, seedlings grown in 164 square centimeters plastic containers, and containergrown seedlings inoculated with vegetative mycelia of Pisolithus tinctorious (Pers.) Coker and Couch. Seedlings at the Mississippi site were planted in a split-plot design at three different elevations, which provided three different natural flooding treatments. Seedlings at the other two sites were planted in a Latin square design at a …

Winter Food Habits And Preferences Of Northern Bobwhites In East Texas, Donald R. Dietz, R. Montague Whiting Jr., Nancy E. Koerth

Faculty Publications

During late winter, 1994 and 1995, we investigated food habits and preferences of northern bobwhites (Colinus virginianus; hereafter, bobwhites) collected on forested lands in east Texas. Crops for bobwhites were collected from areas under 3 management regimes, namely intensively managed for bobwhites (QMA) (i.e., tree basal area reduced, annually burned, numerous multi-stage food plots, etc.), extensively managed for timber and wildlife (NBS) (i.e., burned every 3-5 years, scattered 2-stage food plots with corn feeders), and unmanaged for wildlife (i.e., burned every 5-7 years). With years pooled, partridge pea (Cassia fasciculata), Hercules club (Zanthoxylum clava-herculis), and pine (Pinus spp.) seeds, and …

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 …

Faculty Publications

An increase in obesity prevalence among patients who initiate dialysis may influence the growth of the total ESRD population as a result of improved survival and decreased likelihood for transplantation. Temporal trends in mean body mass index (BMI) and obesity prevalence were examined among incident patients with ESRD by year of dialysis initiation between 1995 and 2002, and these trends were compared with those in the US population during this same period. Among incident dialysis patients, BMI was calculated with the height and estimated dry weight collected from the Centers for Medicare and Medicaid Services End-Stage Renal Disease Medical Evidence …

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, …

Cardiovascular Disease And Associated Risk Factors In Cuba: Prospects For Prevention And Control, Richard S. Cooper, Pedro Orduñez, Marcos D.Iraola Ferrer, Jose Luis Bernal Munoz, Alfredo Espinosa-Brito

Faculty Publications

Objectives. An adequate description of the trends in cardiovascular disease (CVD) is not available for most of the developing world. Cuba provides an important exception, and we sought to use available data to offer insights into the changing patterns of CVD there. Methods. We reviewed Cuban public health statistics, surveys, and reports of health services. Results. CVD has been the leading cause of death since 1970. A 45% reduction in heart disease deaths was observed from 1970 to 2002; the decline in stroke was more limited. There are moderate prevalences of all major risk factors. Conclusions. The Cuban medical care …

Faculty Publications

Serving as a community resource, Panzea is the bioinformatics arm of the Molecular and Functional Diversity in the Maize Genome project. Maize, a classical model for genetic studies, is an important crop species and also the most diverse crop species known. One average, two randomly chosen maize lines have one single-nucleotide polymorphism every ~100 bp; this divergence is roughly equivalent to the differences between humans and chimpanzees. This exceptional genotypic diversity underlies the phenotypic diversity maize needs to be cultivated in a wide range of environments. The Molecular and Functional Diversity in the Maize Genome project aims to understand how …

Sources Of Variation In Nutrient Intakes Among Men In Shanghai, China, Hui Cai, Gong Yang, Yong-Bing Xiang, James R. Hébert, Da-Ke Liu, Wei Zheng, Xiao-Ou Shu

Faculty Publications

Background and objective: Random errors, from any source, will attenuate epidemiological risk estimates. Before we launched the Shanghai Men’s Health Study (SMHS), a large population-based cohort study investigating the diet–cancer association among Chinese men, a dietary calibration study was conducted among 96 men aged 40–75 years (mean age 56.5 years), with biweekly 24-hour dietary recalls (24HDRs) implemented over a 1-year period. Data from this study were analysed to evaluate the nature and magnitude of variances for intake of 26 nutrients among SMHS participants, to compare variance ratios of 26 nutrients among Chinese men and women and individuals in other studies, …

Development And Validation Of The Theistic Spiritual Outcome Survey, P. Scott Richards, Timothy B. Smith, Marion Schowalter, Michael E. Berrett, Randy K. Hardman

Faculty Publications

We developed the Spiritual Outcome Scale (SOS) to measure the spiritual outcomes of psychotherapy from a theistic spiritual perspective. A 17-item version of the SOS was found to have adequate reliability and validity in a sample of college students. Three factors emerged from the analyses that corresponded to subscales labeled Love of God, Love of Others, and Love of Self. Correlations with measures of psychological outcomes were statistically significant. In subsequent analyses, the SOS was administered over an 8-week period to a sample of inpatient women with eating disorders and to two samples from inpatient psychological clinics in Germany. The …

A Preliminary Test Of A Student-Centered Intervention On Increasing Physical Activity In Underserved Adolescents, Dawn K. Wilson, Alexandra E. Evans, Joel Williams, Gary Mixon, John R. Sirard, Russell R. Pate

Faculty Publications

Background - Previous studies have shown that choice and self-initiated behavior changes are important for increasing intrinsic motivation and physical activity (PA), however, little of this research has focused on underserved adolescents.

Purpose - This study examined the effects of a 4-week student-centered intervention on increasing PA in underserved adolescents.

Methods - Twenty-eight students in the intervention school were matched (on race, percentage on free or reduced-price lunch program, gender, and age) with 20 students from another school who served as the comparison group (30 girls, 18 boys; ages 10-12 years; 83% African American; 83% on free or reduced-price lunch). …

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 …

Revised Adult Treatment Panel Iii Guidelines And Cardiovascular Disease Mortality In Men Attending A Preventive Medical Clinic, Chris I. Ardern, Peter T. Katzmarzyk, Ian Janssen, Timothy S. Church, Steven N. Blair

Faculty Publications

Background - National Cholesterol Education Program Adult Treatment Panel III guidelines recommended therapeutic lifestyle changes (TLC) and drug therapy to reduce cardiovascular disease (CVD) risk. These guidelines have been revised recently (ATP III-R); however, the risk of CVD mortality within each intervention window and the effects of cardiorespiratory fitness (CRF) and metabolic syndrome on CVD mortality within the framework of the guidelines are unknown.

Methods and Results - Risk factor and CRF data from 19,125 men (aged 20 to 79 years) who attended a preventive medical clinic between 1979 and 1995 were used. Mortality follow-up was completed until December 31, …

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.

A Global Regulatory Role Of Gluconeogenic Genes In Escherichia Coli Revealed By Transcriptome Network Analysis, Katy Kao, Linh Tran, James Liao

Faculty Publications

In bacterial adaptation to the dynamic environment, metabolic genes are typically thought to be the executors, whereas global transcription regulators are regarded as the decision makers. Although the feedback from metabolic consequence is believed to be important, much less is understood. This work demonstrates that the gluconeogenic genes in Escherichia coli, ppsA, sfcA, and maeB, provide a feedback loop to the global regulator, cAMP receptor protein (CRP), in carbon source transition. Disruption of one of the gluconeogenic pathways has no phenotype in balanced growth, but causes a significant delay in the diauxic transition from glucose to acetate. To investigate the …

Faculty Publications

Background: The Family Blood Pressure Program is an ongoing, NHLBI-sponsored, multi-center program to study the genetic determinants of high blood pressure. The goal of this particular study was to study patterns of metabolic syndrome (MetS) in four ethnic groups: African Americans, Caucasians, Hispanics, and Asians. Methods: A major part of participants in three networks GENOA, HyperGEN and SAPPHIRe were recruited mainly through hypertensive probands. MetS was defined as a categorical trait following the National Cholesterol Education Program definition (c-MetS). MetS was also characterized quantitatively through multivariate factor analyses (FA) of 10 risk variables (q-MetS). Logistic regression and frequency tables were …

Extraocular Muscle Activity, Rapid Eye Movements And The Development Of Active And Quiet Sleep, Adele M. H. Seelke, Andrew J. Gall, Karl Æ. Karlsson, Mark S. Blumberg

Faculty Publications

Rapid eye movements (REMs), traditionally measured using the electrooculogram (EOG), help to characterize active sleep in adults. In early infancy, however, they are not clearly expressed. Here we measured extraocular muscle activity in infant rats at 3 days of age (P3), P8 and P14-15 in order to assess the ontogeny of REMs and their relationship with other forms of sleep-related phasic activity. We found that the causal relationship between extraocular muscle twitches and REMs strengthened during the first two postnatal weeks, reflecting increased control of the extraocular muscles over eye movements. As early as P3, however, phasic bursts of extraocular …

Baseline cardiorespiratory fitness was quantified as duration of a maximal treadmill test. Metabolic syndrome was defined with NCEP ATP-III criteria. During a …

Effects Of Long-Term Storage On Quality Of Retail-Packaged Pinto Beans, C. M. Larson, A. R. Sloan, Lynn V. Ogden, Oscar A. Pike

Faculty Publications

There is interest in storing low-moisture foods for long periods of time for uses such as personal preparedness, disaster relief efforts and space travel. Pinto beans in restaurant-sized No. 10 cans are available in the retail market, but work is needed to determine the effects of long-term storage on quality. The objective of this research was to investigate the quality of retail-packaged pinto beans held at ambient temperatures up to 32 years. Fifteen samples of pinto beans packaged in No. 10 cans, which were treated to remove oxygen, were obtained from donors. Samples ranged from <1 to 32 years in age. Prior to cooking, pinto bean samples were soaked in water containing varying levels of baking soda to standardize textural attributes.

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 …
