Leptospira Interrogans Induces Apoptosis In Macrophages Via Caspase-8- And -3-Dependent Pathways, Dandan Jin, David M. Ojcius, Dexter Sun, Haiyan Dong, Yihui Luo, Yafei Mao, Jie Yan

All Dugoni School of Dentistry Faculty Articles

Apoptosis of host cells plays an important role in modulating the pathogenesis of many infectious diseases. It has been reported that Leptospira interrogans, the causal agent of leptospirosis, induces apoptosis in macrophages and hepatocytes. However, the molecular mechanisms responsible for host cell death remained largely unknown. Here we demonstrate that L. interrogans induced apoptosis in a macrophage-like cell line, J774A.1, and primary murine macrophages in a time- and dose-dependent manner. Apoptosis was associated with the activation of cysteine aspartic acid-specific proteases (caspase-3, caspase-6, and caspase-8), the increased expression of Fas-associated death domain (FADD), and the cleavage of the caspase substrates …


Acquired Appetitive Responding To Intravenous Nicotine Reflects A Pavlovian Conditioned Association, Jennifer E. Murray, Rick A. Bevins Feb 2009

Acquired Appetitive Responding To Intravenous Nicotine Reflects A Pavlovian Conditioned Association, Jennifer E. Murray, Rick A. Bevins

Department of Psychology: Faculty Publications

Recent research examining Pavlovian appetitive conditioning has extended the associative properties of nicotine from the unconditioned stimulus or reward to include the role of a conditional stimulus (CS), capable of acquiring the ability to evoke a conditioned response. To date, published research has used presession extravascular injections to examine nicotine as a contextual CS in that appetitive Pavlovian drug discrimination task. Two studies in the current research examined whether a nicotine CS can function discretely, multiple times within a session using passive iv infusions. In Experiment 1, rats readily acquired a discrimination in conditioned responding between nicotine and saline infusions …

Changes In Weight, Waist Circumference And Compensatory Responses With Different Doses Of Exercise Among Sedentary, Overweight Postmenopausal Women, Timothy S. Church, Corby K. Martin, Angela M. Thompson, Conrad P. Earnest, Catherine R. Mikus, Steven N. Blair

Faculty Publications

Background: It has been suggested that exercise training results in compensatory mechanisms that attenuate weight loss. However, this has only been examined with large doses of exercise. The goal of this analysis was to examine actual weight loss compared to predicted weight loss (compensation) across different doses of exercise in a controlled trial of sedentary, overweight or obese postmenopausal women (n=41).

Methodology/Principal Findings: Participants were randomized to a non-exercise control (n=94) or 1 of 3 exercise groups; exercise energy expenditure of 4 (n=139), 8 (n=85), or 12 (n=93) kcal/kg/week (KKW). Training intensity was set at the heart rate associated with …

OBJECTIVE. Intimate partner violence harms victims as well as families and communities. Many barriers account for limited intimate partner violence screening by nurses. The purpose of this study was to measure how participation in a curriculum about screening parents for intimate partner violence, at a pediatric hospital, affects a nurse's knowledge, attitudes, behaviors, and self-efficacy for intimate partner violence screening.

METHODS. In this interventional, longitudinal study, data were collected before participation in an intimate partner violence screening curriculum, after participation, and 3 months later. The measurement tool was adapted from Maiuro's (2000) Self-efficacy for Screening for Intimate Partner Violence Questionnaire. …


Efficacy And Efficiency In Natural Family Planning Services, Richard J. Fehring Feb 2009

Efficacy And Efficiency In Natural Family Planning Services, Richard J. Fehring

College of Nursing Faculty Research and Publications

Relatively few Catholic couples in the United States use modern methods of natural family planning (NFP). So too, few Catholic physicians and health professionals prescribe the use of NFP methods for their patients. Reasons for low use of NFP methods include their perceived low efficacy; the complexity of learning, using, and teaching these methods; and the prolonged (and often unnecessary) required abstinence. Newer and simplified methods of NFP have been developed by physicians and scientists that are less complex and use modern technologies of detecting fertility and communicating instructions. Catholic physicians and scientists need to continue to answer the call …

Faculty, Staff and Student Publications

Glutathione S-transferase (GST) genes detoxify and metabolize carcinogens, including oxygen free radicals which may contribute to salivary gland carcinogenesis. This cancer center-based case-control association study included 166 patients with incident salivary gland carcinoma (SGC) and 511 cancer-free controls. We performed multiplex polymerase chain reaction-based polymorphism genotyping assays for GSTM1 and GSTT1 null genotypes. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated with multivariable logistic regression analyses adjusted for age, sex, ethnicity, tobacco use, family history of cancer, alcohol use and radiation exposure. In our results, 27.7% of the SGC cases and 20.6% of the controls were null for …

Mutual Information For Testing Gene-Environment Interaction, Xuesen Wu, Li Jiin, Momiao Xiong

Faculty, Staff and Student Publications

Despite current enthusiasm for investigation of gene-gene interactions and gene-environment interactions, the essential issue of how to define and detect gene-environment interactions remains unresolved. In this report, we define gene-environment interactions as a stochastic dependence in the context of the effects of the genetic and environmental risk factors on the cause of phenotypic variation among individuals. We use mutual information that is widely used in communication and complex system analysis to measure gene-environment interactions. We investigate how gene-environment interactions generate the large difference in the information measure of gene-environment interactions between the general population and a diseased population, which motives …

Atorvastatin May Have No Effect On Acute Phase Reaction In Children After Intravenous Bisphosphonate Infusion., Tarak Srivastava, Connie J. Haney, Uri S. Alon

Manuscripts, Articles, Book Chapters and Other Papers

Intravenous bisphosphonate therapy is associated with acute phase reaction characterized by fever and musculoskeletal pain. Bisphosphonates have been shown in vitro to activate gammadeltaT-cells to proliferate and produce cytokines, suggesting a role in acute phase reaction, which can be effectively blocked by statins. We conducted a double-blind randomized crossover placebo controlled study in 12 children (12.1 +/- 4.2 yr; 10 girls and 2 boys) receiving intravenous bisphosphonates to evaluate whether statins can be used to prevent acute phase reaction associated with therapy. Children received two cycles given 3-4 mo apart of intravenous bisphosphonate given on 2 consecutive days in each …

Pathology, East Africa

Helicobacter pylori is the main cause of peptic ulceration, distal gastric adenocarcinoma, and gastric lymphoma.1 Worldwide, gastric cancer is the second most common malignancy in men and women.1 According to data from the Nairobi Cancer Registry, gastric cancer is the fourth most common malignancy in adult males and the fifth most common in adult females. However, this may not represent the true situation because of under-reporting of cases. In the development of gastric cancer, environmental factors such as smoking, diet and, in particular, infection with H. pylori are significant.1 Based on epidemiological studies, the International Agency for Research on Cancer …

A Structural Interpretation Of The Effect Of Gc-Content On Efficiency Of Rna Interference, Chi Yu Chan, C Steven Carmack, Dang D. Long, Anil Maliyekkel, Yu Shao, Igor Roninson, Ye Ding

Faculty Publications

BACKGROUND: RNA interference (RNAi) mediated by small interfering RNAs (siRNAs) or short hairpin RNAs (shRNAs) has become a powerful technique for eukaryotic gene knockdown. siRNA GC-content negatively correlates with RNAi efficiency, and it is of interest to have a convincing mechanistic interpretation of this observation. We here examine this issue by considering the secondary structures for both the target messenger RNA (mRNA) and the siRNA guide strand. RESULTS: By analyzing a unique homogeneous data set of 101 shRNAs targeted to 100 endogenous human genes, we find that: 1) target site accessibility is more important than GC-content for efficient RNAi; 2) …

Multiple Independent Genetic Factors At Nos1ap Modulate The Qt Interval In A Multi-Ethnic Population, Dan E. Arking, Amit Khera, Chao Xing, W H Linda Kao, Wendy Post, Eric Boerwinkle, Aravinda Chakravarti

Faculty, Staff and Student Publications

Extremes of electrocardiographic QT interval are associated with increased risk for sudden cardiac death (SCD); thus, identification and characterization of genetic variants that modulate QT interval may elucidate the underlying etiology of SCD. Previous studies have revealed an association between a common genetic variant in NOS1AP and QT interval in populations of European ancestry, but this finding has not been extended to other ethnic populations. We sought to characterize the effects of NOS1AP genetic variants on QT interval in the multi-ethnic population-based Dallas Heart Study (DHS, n = 3,072). The SNP most strongly associated with QT interval in previous samples …
