How Family Religious Involvement Benefits Adults, Youth, And Children And Strengthens Families, David C. Dollahite, Jennifer Y. Thatcher

Faculty Publications

A growing body of empirical research demonstrates that a family’s religious involvement directly benefits adults, children and youth in many ways. Divorce rates are lower and marital satisfaction and quality scores highest among religiously involved couples. Religious practices are linked with family satisfaction, closer father-child relationships, and closer parent-child relationships. There is less domestic violence among more religious couples and religious parents are less likely to abuse or yell at their children. Religious involvement promotes involved and responsible fathering and is associated with more involved mothering. Greater religiosity in parents and youth is associated with a variety of protective factors …

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, …

Modulation Of Synaptic Function In Retinal Amacrine Cells, Brian K. Hoffpauir, Evanna L. Gleason

Faculty Publications

Amacrine cells are interneurons that have diverse functions in retinal signal processing. In order to study signaling and modulation in retinal amacrine cells, we employ a simplified culture system containing identifiable GABAergic amacrine cells. Immunocytochemistry experiments indicate that GABAergic amacrine cells express metabotropic glutamate receptor 5 (mGluR5), a group I mGluR usually linked to the IP3 signaling pathway. Ca2+ imaging experiments using an mGluR5-specific agonist indicate that these receptors are functional and when activated, can stimulate temporally diverse Ca2+ elevations. To begin to establish the role of these receptors in modulating amacrine cell function, we have used electrophysiological methods to …

The Implications Of Conjunctive And Disjunctive Forgiveness For Sexual Abuse, Herbert W. Helm, Jonathan R. Cook, John M. Berecz

Faculty Publications

This article examines the relationship between forgiveness styles (conjunctive and disjunctive models) and sexual abuse. Surveys from 114 university students were analyzed for differences between non-sexually abused and sexually abused subjects on a number of psychological and physical well-being variables. A number of differences were found including higher levels of reported verbal and physical abuse for the sexually abused subjects. Only one sexually abused subject was found that fit the pattern of conjunctive forgiveness (one of reconciliation) towards the offender. The majority of sexually abused subjects preferred to keep their distance from the abuser, regardless of the extent to which …

Providing End-Of-Life Care To Patients: Critical Care Nurses' Perceived Obstacles And Supportive Behaviors, Renea L. Beckstrand, Karin T. Kirchhoff

Faculty Publications

Soy Isoflavone Glycitein Protects Against Beta Amyloid-Induced Toxicity And Oxidative Stress In Transgenic Caenorhabditis Elegans, Astrid Gutierrez-Zepeda, Ross Santell, Zhixin Wu, Marishka Brown, Yanjue Wu, Ikhlas Khan, Christopher D. Link, Baolu Zhao, Yuan Luo

Faculty Publications

Background

Epidemiological studies have associated estrogen replacement therapy with a lower risk of developing Alzheimer's disease, but a higher risk of developing breast cancer and certain cardiovascular disorders. The neuroprotective effect of estrogen prompted us to determine potential therapeutic impact of soy-derived estrogenic compounds. Transgenic C. elegans, that express human beta amyloid (Aβ), were fed with soy derived isoflavones genistein, daidzein and glycitein (100 μg/ml) and then examined for Aβ-induced paralysis and the levels of reactive oxygen species.

Results

Among the three compounds tested, only glycitein alleviated Aβ expression-induced paralysis in the transgenic C. elegans. This activity of …

Animal Virus Replication And Rnai-Mediated Antiviral Silencing In Caenorhabditis Elegans, R. Lu, M. Maduro, F. Li, H. W. Li, G. Broitman-Maduro, W. X. Li, S. W. Ding

Faculty Publications

The worm Caenorhabditis elegans is a model system for studying many aspects of biology, including host responses to bacterial pathogens, but it is not known to support replication of any virus. Plants and insects encode multiple Dicer enzymes that recognize distinct precursors of small RNAs and may act cooperatively. However, it is not known whether the single Dicer of worms and mammals is able to initiate the small RNA-guided RNA interference (RNAi) antiviral immunity as occurs in plants and insects. Here we show complete replication of the Flock house virus (FHV) bipartite, plus-strand RNA genome in C. elegans. We show …

A Mechanism For Assembly Of Complexes Of Vitronectin And Plasminogen Activator Inhibitor-1 From Sedimentation Velocity Analysis, Kenneth H. Minor, Christine R. Schar, Grant E. Blouse, Joseph D. Shore, Daniel A. Lawrence, Peter Schuck, Cynthia B. Peterson

Faculty Publications

Plasminogen activator inhibitor-1 (PAI-1) and vitronectin are cofactors involved in pathological conditions such as injury, inflammation, and cancer, during which local levels of PAI-1 are increased and the active serpin forms complexes with vitronectin. These complexes become deposited into surrounding tissue matrices, where they regulate cell adhesion and pericellular proteolysis. The mechanism for their co-localization has not been elucidated. We hypothesize that PAI-1-vitronectin complexes form in a stepwise and concentration-dependent fashion via 1:1 and 2:1 intermediates, with the 2:1 complex serving a key role in assembly of higher order complexes. To test this hypothesis, sedimentation velocity experiments in the analytical …

An Evaluation Of The Metabolic Syndrome In A Large Multi-Ethnic Study: The Family Blood Pressure Program, Aldi T. Kraja, D. C. Rao, Alan B. Weder, Thomas H. Mosley, Stephen T. Turner, Chao Agnes Hsiung, Thomas Quertermous, Richard Cooper, J. David Curb, Michael A. Province

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 …

Altering The Tropism Of Lentiviral Vectors Through Pseudotyping, James Cronin, Xian Yang Zhang, Jakob Reiser

Faculty Publications

The host range of retroviral vectors including lentiviral vectors can be expanded or altered by a process known as pseudotyping. Pseudotyped lentiviral vectors consist of vector particles bearing glycoproteins (GPs) derived from other enveloped viruses. Such particles possess the tropism of the virus from which the GP was derived. For example, to exploit the natural neural tropism of rabies virus, vectors designed to target the central nervous system have been pseudotyped using rabies virus-derived GPs. Among the first and still most widely used GPs for pseudotyping lentiviral vectors is the vesicular stomatitis virus GP (VSV-G), due to the very broad …

From The Margins Of The Genome: Mobile Elements Shape Primate Evolution, Dale J. Hedges, Mark A. Batzer

Faculty Publications

As is the case with mammals in general, primate genomes are inundated with repetitive sequence. Although much of this repetitive content consists of "molecular fossils" inherited from early mammalian ancestors, a significant portion of this material comprises active mobile element lineages. Despite indications that these elements played a major role in shaping the architecture of the genome, there remain many unanswered questions surrounding the nature of the host-element relationship. Here we review advances in our understanding of the host-mobile element dynamic and its overall impact on primate evolution. © 2005 Wiley Periodicals, Inc.

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 …

Sex-Related Acoustic Changes In Voiceless English Fricatives, Shawn L. Nissen, Robert Allen Fox

Faculty Publications

This investigation is a comprehensive acoustic study of 4 voiceless fricatives (/f θ s ʃ/) in English produced by adults and pre-and postpubescent children aged 6-14 years. Vowel duration, amplitude, and several different spectral measures (including spectral tilt and spectral moments) were examined. Of specific interest was the pattern of normal development of the acoustic properties of fricatives and the nature of sex-specific patterns of fricative articulation in prepubescent children. Little evidence of amplitude or duration differences was found between speakers that was related to the sex of the speaker. However, significant sex-specific differences in fricative articulation were found in …

Cardiorespiratory Fitness Is Inversely Associated With The Incidence Of Metabolic Syndrome: A Prospective Study Of Men And Women, Michael J. Lamonte, Carolyn E. Barlow, Radim Jurca, James B. Kampert, Timothy S. Church, Steven N. Blair

Faculty Publications

Background - Few studies have reported the relationship between cardiorespiratory fitness and metabolic syndrome incidence, particularly in women.

Methods and Results - We prospectively studied 9007 men (mean±SD, age, 44±9 years; body mass index, 25±3 kg/m²) and 1491 women (age, 44±9 years; body mass index, 22±2 kg/m²) who were free of metabolic syndrome and for whom measures of waist girth, resting blood pressure, fasting lipids, and glucose were taken during baseline and follow-up examinations. Baseline cardiorespiratory fitness was quantified as duration of a maximal treadmill test. Metabolic syndrome was defined with NCEP ATP-III criteria. During a …

Enhancement Of Calcium-Dependent Afterpotentials In Oxytocin Neurons Of The Rat Supraoptic Nucleus During Lactation, Ryoichi Teruyama, William E. Armstrong

Faculty Publications

The firing pattern of oxytocin (OT) hormone synthesizing neurons changes dramatically immediately before each milk ejection, when a brief burst of action potentials is discharged. OT neurons possess intrinsic currents that would modulate this burst. Our previous studies showed the amplitude of the Ca2+-dependent afterhyperpolarization (AHP) following spike trains is significantly larger during lactation. In the present study we sought to determine which component of the AHP is enhanced, and whether the enhancement could be related to changes in whole-cell Ca2+ current or the Ca2+ transient in identified OT or vasopressin (VP) neurons during lactation. We confirmed, with whole-cell current-clamp …

Exclusive electroproduction of φ mesons has been studied in e±p collisions at √s = 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 65.1 pb-1. The γ* p cross section is presented in the kinematic range 2 GeV2 < Q2 < 70 GeV2, 35 GeV < W < 145 GeV and t < 0.6 GeV2. The cross sections as functions of Q2, W, t and helicity angle θh are compared to cross sections for other vector mesons. The ratios R of the cross sections for longitudinally and transversely polarized virtual photons are presented as functions of Q2 and W. The data are also compared to predictions from theoretical models. © 2005 Elsevier B.V. All rights reserved.

The 'Abuse Excuse' In Capital Sentencing Trials: Is It Relevant To Responsibility, Punishment, Or Neither?, Paul J. Litton

Faculty Publications

The violent criminal who was a victim of severe childhood abuse frequently appears in the responsibility literature because he presents a difficulty for theorists who maintain the compatibility of causal determinism and our practices of holding persons responsible. The challenge is based on the fact that learning about an offender's horrific childhood mitigates the indignation that many persons feel towards him, possibly indicating that they hold him less than fully responsible. Many capital defendants present evidence of suffering childhood abuse, and many jurors find this evidence to count against imposing death. The most obvious explanation for a response like this …

Psychometric Properties Of The Self-Efficacy For Exercise Questionnaire In A Diverse Sample Of Men And Women, Sarah Wilcox, Patricia A. Sharpe, Brent E. Hutto, Michelle L. Granner

Faculty Publications

Background: Self-efficacy is a consistent correlate of physical activity, but most self-efficacy measures have not been validated in diverse populations. This study examined the construct, criterion-related, and convergent validity and internal consistency of the Self-Efficacy for Exercise Questionnaire. Methods: African American and Caucasian adults (N = 1919) from two adjacent counties in South Carolina were identified through a list-assisted random digit-dialed telephone survey. Psychometric properties of the measure were assessed by gender, race, age, education, and body weight subgroups. Results: Across all subgroups, a single-factor solution explained 93 to 98% of the common variance in an exploratory factor analysis, …

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 …

Left Ventricular Hypertrophy Is More Prevalent In Blacks Than Whites In The General Population: The Dallas Heart Study, Mark H. Drazner, Daniel L. Dries, Ronald M. Peshock, Richard S. Cooper, Chris Klassen, Farhana Kazi, Du Wayne Willett, Ronald G. Victor

Faculty Publications

Although recent studies have suggested that blacks compared with whites have an increased prevalence of left ventricular hypertrophy, it remains uncertain whether this is true despite adjustment for body composition (fat mass and fat-free mass) and when assessed by cardiac MRI in the general population. The Dallas Heart Study is a population-based study of Dallas County in which 1335 black and 858 white participants 30 to 67 years of age underwent detailed assessment including dual-energy x-ray absorptiometry scan to measure body composition and cardiac MRI. Left ventricular hypertrophy, whether defined by indexation to body surface area (P<0.001), fat-free mass (P=0.002), or height2.7 (P<0.001) was 2- to 3-fold more common in black versus white women. Similar results were seen when comparing black and white men (P<0.001 when left ventricular hypertrophy was indexed to body surface area or height2.7 and P=0.05 when indexed to fat-free mass). Ethnic disparities in left ventricular mass persisted in multivariable models despite adjustment for fat mass, fat-free mass, systolic blood pressure, age, gender, and measures of socioeconomic status. We conclude that blacks compared with whites have increased left ventricular mass and a 2-to 3-fold higher prevalence of left ventricular hypertrophy in the general population, as assessed by cardiac MRI. The ethnic differences in left ventricular mass are independent of differences in body composition. © 2005 American Heart Association, Inc.

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%, …
