Faculty Publications

Performance of lactating dairy cows fed diets containing either mechanically delinted whole cottonseed (DWCS; 3.7% lint) or linted whole cottonseed (LWCS; 11.7% lint) was measured. Forty primiparous (86 ± 39 d in milk) and 40 multiparous (88 ± 30 d in milk) cows were fed a total mixed ration containing 13% (dry matter basis) DWCS or LWCS in two blocks of 112 d (n = 53 and 27, respectively). Other total mixed ration ingredients (dry matter basis) were corn silage (28.1%), alfalfa silage (23%), high moisture shelled corn (27.8%), soybean meal (1.8%), expeller soybean meal (1.8%), blood meal (2%), and …

Effects Of Zinc And Sodium Monensin On Ruminal Degradation Of Lysine-Hci And Liquid 2-Hydroxy-4-Methylthiobutanoic Acid, H. G. Bateman, C. C. Williams, D. T. Gantt, Y. H. Chung, A. E. Beem, C. C. Stanley, G. E. Goodier, P. G. Hoyt, J. D. Ward, L. D. Bunting

Faculty Publications

Four nonlactating, mature, Holstein cows were fitted with ruminal cannula and used in a 4 x 4 Latin square-designed experiment to evaluate the impact of supplemental Zn and monensin on ruminal degradation of Lys and liquid 2-hydroxy-4-methylthiobutanoic acid (HMB). Cows were fed 4.54 kg (as fed) of alfalfa hay top-dressed with 4.54 kg (as fed) concentrate once daily. Concentrates were formulated to provide 0 or 500 mg/kg of Zn as ZnSO4 and 0 or 40 mg/kg of monensin in the total diet. Zinc supplementation provided approximately 22-fold greater dietary Zn than estimated by NRC requirements. On d 14 of each …

Response Of A Gall-Forming Guild (Hymenoptera: Cynipidae) To Stressed And Vigorous Prairie Roses, Mark A. Williams, James T. Cronin

Faculty Publications

Two general hypotheses that describe the relationship between plant quality and host-plant preference of insect herbivores are the plant-stress and plant-vigor hypotheses. We examined the response of a gall-forming guild of insect herbivores associated with prairie rose, Rosa arkansana Porter (Rosaceae), to experimental manipulations of plant stress (addition of NaCl) and vigor (addition of nitrogen; NH4NO3). The most common members of the gall-forming guild on roses are Diplolepis ignota Osten Sacken, D. nodulosa Beutenmüller, and D. rosaefolii Cockerell (Hymenoptera: Cynipidae). The repeated application of nitrogen throughout the growing season to prairie plots resulted in significantly higher plant nitrogen levels and …

Hypertension Treatment And Control In Five European Countries, Canada, And The United States, Katharina Wolf-Maier, Richard S. Cooper, Holly Kramer, José R. Banegas, Simona Giampaoli, Michel R. Joffres, Neil Poulter, Paola Primatesta, Birgitta Stegmayr, Michael Thamm

Faculty Publications

Levels of hypertension treatment and control have been noted to vary between Europe and North America, although direct comparisons with similar methods have not been undertaken. In this study, we sought to estimate the relative impact of hypertension treatment strategies in Germany, Sweden, England, Spain, Italy, Canada, and the United States by using sample surveys conducted in the 1990s. Hypertension was defined as a blood pressure of 160/95 mm Hg or 140/90 mm Hg, plus persons taking antihypertensive medication. "Controlled hypertension" was defined as a blood pressure less than threshold among persons taking antihypertensive medications. Among persons 35 to 64 …

Impaired Glucose Regulation In Adults In Jamaica: Who Should Have The Oral Glucose Tolerance Test?, Lincoln A. Sargeant, Michael S. Boyne, Franklyn I. Bennett, Terrence E. Forrester, Richard S. Cooper, Rainford J. Wilks

Faculty Publications

Objective. To compare the 1999 World Health Organization (WHO) fasting plasma glucose (FPG) criteria and the WHO 2-hour post-challenge glucose (2hPG) criteria during an oral glucose tolerance test (OGTT) in identifying adults in Jamaica with hyperglycemia. As the OGTT is not commonly used in clinical practice, factors associated with the failure of the FPG criteria to detect persons with impaired 2hPG were investigated. Methods. A random sample of 2 096 adults, 25-74 years old, living in the town of Spanish Town, Jamaica, was evaluated for diabetes. After excluding 215 individuals for reasons such as missing data, the remaining 1 881 …

Influence Of Drought Stress On Sweetpotato Resistance To Sweetpotato Weevil, Cylas Formicarius (Coleoptera: Apoinidae), And Storage Root Chemistry, Lixin Mao, Louis E. Jett, Richard N. Story, Abner M. Hammond, Joseph K. Peterson, Don R. Labonte

Faculty Publications

The effect of drought stress on the resistance of sweetpotato roots to sweetpotato weevil (SPW), Cylas formicarius (Fab.), was studied in 1997 and 1998 in two genotypes ("Beauregard" and "Excel") with different SPW susceptibility. Storage roots produced under drought or normal conditions were tested for adult feeding, oviposition, larval survival and pupal weight in the laboratory under no-choice and free-choice test conditions. The levels of sweetpotato resin glycoside and caffeic acid in the periderm tissue of the roots were also determined. Drought-stressed roots received significantly more SPW eggs under no-choice and free-choice conditions and more feeding punctures under free-choice conditions …

Is Modernism Really Modern? Uncovering A Fallacy In Postmodernism, William D. Harpine

Faculty Publications

Some postmodernists criticize the view that the logics of Western thought can be employed universally. In doing so, they assume without adequate proof that different human societies have greatly different rationalities and employ completely different logics. This essay argues that, on the contrary, widely different cultures often share noteworthy similarities in rationality.

Feeding And Maturation By Soybean Looper (Lepidoptera: Noctuidae) Larvae On Soybean Affected By Weed, Fungus, And Nematode Pests, Carol H. Carter-Wientjes, John S. Russin, David J. Boethel, James L. Griffin, Edward C. Mcgawley

Faculty Publications

Feeding and maturation by the soybean looper, Pseudoplusia includens (Walker) (Lepidoptera: Noctuidae), were investigated in a 2-yr study on 'Davis' soybean, Glycine max (L.) Merr., grown alone and combined with the weed hemp sesbania, Sesbania exaltata (Raf.) Rybd. ex. A. W. Hill, the root-knot nematode, Meloidogyne incognita (Kofoid & White) Chitwood, and the charcoal rot fungus, Macrophomina phaseolina (Tassi) Goid. Of the three pests, hemp sesbania had the greatest effects on plant growth and insect feeding and maturation. When fed foliage from soybean stressed by hemp sesbania, soybean looper larvae remained longer in feeding stages, consumed more foliage, and showed …

Long-Lived Worms And Aging, Yuan Luo

Faculty Publications

Several investigators have generated long-lived nematode worms (Caenorhabditis elegans) in the past decade by mutation of genes in the organism in order to study the genetics of aging and longevity. Dozens of longevity assurance genes (LAG) that dramatically increase the longevity of this organism have been identified. All long-lived mutants of C. elegans are also resistant to environmental stress, such as high temperature, reactive oxygen species (ROS), and ultraviolet irradiation. Double mutations of some LAGS further extended life span up to 400%, providing more insight into cellular mechanisms that put limits on the life span of organisms. With …

Multiple Domains Of The Co-Chaperone Hop Are Important For Hsp70 Binding, Gregory M. Nelson, Patricia E. Carrigan, Patricia J. Roberts, Jha'nae Stoffer, Daniel L. Riggs, David F. Smith

Faculty Publications

The Hop/Sti1 co-chaperone binds to both Hsp70 and Hsp90. Biochemical and co-crystallographic studies have suggested that the EEVD-containing C terminus of Hsp70 or Hsp90 binds specifically to one of the Hop tetratricopeptide repeat domains, TPR1 or TPR2a, respectively. Mutational analyses of Hsp70 and Hop were undertaken to better characterize interactions between the C terminus of Hsp70 and Hop domains. Surprisingly, truncation of EEVD plus as many as 34 additional amino acids from the Hsp70 C terminus did not reduce the ability of Hsp70 mutants to co-immunoprecipitate with Hop, although further truncation eliminated Hop binding. Hop point mutations targeting a carboxylate …

Effects Of Low Tide Rainfall On Intertidal Zone Material Cycling, Raymond Torres, Miguel A. Goni, George Voulgaris, Charles R. Lovell, James T. Morris

Faculty Publications

Sediment transport by rainfall-runoff processes is well documented for terrestrial landscapes but few studies have focused on rainfall-runoff effects in intertidal areas. Here we present geochemical analyses performed on sediment samples collected during low tide irrigation experiments, and tidal channel turbidity measurements taken during natural rainfall over North Inlet Marsh, South Carolina. Order of magnitude approximations indicate that a single 10 minute storm may entrain 8-15% of the local annual average sediment accumulation. This rainfall-entrained material is enriched in organic nitrogen and marine algal matter, and therefore of high nutritional quality.

Muscular Fitness And All-Cause Mortality: Prospective Observations, Shannon J. Fitzgerald, Carolyn E. Barlow, James B. Kampert, James R. Morrow Jr., Allen W. Jackson, Steven N. Blair

Background: The beneficial effects of cardiorespiratory fitness on mortality are well known; however, the relation of muscular fitness, specifically muscular strength and endurance, to mortality risk has not been thoroughly examined. The purpose of the current study is to determine if a dose-response relation exists between muscular fitness and mortality after controlling for factors such as age and cardiorespiratory fitness.

Methods: The study included 9105 men and women, 20-82 years of age, in the Aerobics Center Longitudinal Study who have completed at least one medical examination at the Cooper Clinic in Dallas, TX between 1981 and 1989. The exam included …

Regulating Genetically Modified Foods: Is Mandatory Labeling The Right Answer?, Jonathan H. Adler

Faculty Publications

What I want to talk about are some legal issues relating to labeling and, in particular, constitutional issues relating to mandatory labeling for genetically modified foods or food products that may contain genetically modified components. This is a separate issue from whether or not the FDA, or some other agency, has sufficient statutory authority at present to mandate labeling, and that is something worth discussing. Even if they do have such authority, or even if Congress tomorrow were to give the FDA such authority or were to require the FDA to impose labels on genetically modified foods, or if a …

Economic Measurements And Quality Of Life In Mexico, Constantine P. Danopoulos

Faculty Publications

Using the Genuine Progress Indicator (GPI), the article seeks to evaluate the quality of life in modern Mexico. The GPI employs the same indicators used to arrive at per capita GDP, but adds positive and negative monetary and non-monetary actors that affect people's lives. Monetary factors include income distribution, increased health care cost due to air and water pollution, and loss of wetlands. Non-monetary factors involve parenting, time spent in highways, loss of leisure time, the cost of volunteer work, and other social costs. If one takes these into account, the purchasing power and quality of life of Mexican citizens …

Analysis Of End-Of-Life Content In Critical Care Nursing Textbooks, Karin T. Kirchhoff, Renea L. Beckstrand, Prashanth Reddy Anumandla

Faculty Publications

Nurses have identified a need for improving their knowledge and skills in providing end-of-life care. Critical care nursing textbooks can serve as an important source of information on end-of-life care for critical care nurses. Hence, an analysis of end-of-life content in 14 critical care nursing textbooks was conducted. Critical care nursing textbooks used for review were published in 1995 or later and identified from the libraries at the University of Wisconsin-Madison and Brigham Young University. The end-of-life content areas identified by the American Association of Colleges of Nursing (AACN), under which the AACN end-of-life competencies for undergraduate nursing students can …

Understanding Why Adult Participants At The World Senior Games Choose A Healthy Diet, Ray M. Merrill, Eric C. Shields

Faculty Publications

Identifying those seniors most likely to adopt a healthy diet, the relative importance they place on certain perceived benefits associated with a healthy diet, and whether these perceived benefits are associated with selected demographic, lifestyle, and health history variables is important for directing effective dietary health promotion programs. Methods: Analyses are based on a cross-sectional convenience sample of 670 seniors aged 50 years and older at the 2002 World Senior Games in St. George, Utah. Data are assessed using frequencies, bivariate analysis, analysis of variance, and multiple logistic regression analysis. Results Fruit and vegetable consumption was significantly higher in individuals …

Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague

Faculty Publications

Eutherians give birth to relatively large infants. Females have larger pelves than males, though males typically have larger nonpelvic bones. Pelvic dimorphism is an adaptation for parturition. Metatherian females, who give birth to markedly small infants, should not show pelvic adaptations for parturition and should have smaller pelves than males. Adult females and males of the Virginia opossum, Didelphis virginiana, are compared. Males are significantly larger than females in absolute size for 14 of 16 pelvic and 8 nonpelvic measures. Sexes did not differ significantly for lower iliac length and posterior space of midplane. However, relative lengths for females are …

Validation Of A 3-Day Physical Activity Recall Instrument In Female Youth, Russell R. Pate, Rebecca Ross, Marsha Dowda, Stewart G. Trost, John R. Sirard

Faculty Publications

The purpose of this study was to examine the validity of the 3-Day Physical Activity Recall (3DPAR) self-report instrument in a sample of eighth and ninth grade girls (n= 70, 54.3% white, 37.1% African American). Criterion measures of physical activity were derived using the CSA 7164 accelerometer. Participants wore a CSA monitor for 7 consecutive days and completed the self-report physical activity recall for the last 3 of those days. Self-reported total METs, 30-min blocks of MVPA, and 30-min blocks of VPA were all significantly correlated with analogous CSA variables for 7 days (r=0.35-0.51; P<0.01) and 3 days (r …
