Simulation Of Drosophila Circadian Oscillations, Mutations, And Light Responses By A Model With Vri, Pdp-1, And Clk, Paul Smolen, Paul E. Hardin, Brian S. Lo, Douglas A. Baxter, John H. Byrne

Faculty, Staff and Student Publications

A model of Drosophila circadian rhythm generation was developed to represent feedback loops based on transcriptional regulation of per, Clk (dclock), Pdp-1, and vri (vrille). The model postulates that histone acetylation kinetics make transcriptional activation a nonlinear function of [CLK]. Such a nonlinearity is essential to simulate robust circadian oscillations of transcription in our model and in previous models. Simulations suggest that two positive feedback loops involving Clk are not essential for oscillations, because oscillations of [PER] were preserved when Clk, vri, or Pdp-1 expression was fixed. However, eliminating positive feedback by fixing vri expression altered the oscillation period. Eliminating …

Conversion Of Myoblasts To Physiologically Active Neuronal Phenotype, Yumi Watanabe, Sei Kameoka, Vidya Gopalakrishnan, Kenneth D Aldape, Zhizhong Z Pan, Frederick F Lang, Sadhan Majumder

Faculty, Staff and Student Publications

Repressor element 1 (RE1)-silencing transcription factor (REST)/neuron-restrictive silencer factor (NRSF) can repress several terminal neuronal differentiation genes by binding to a specific DNA sequence (RE1/neuron-restrictive silencer element [NRSE]) present in their regulatory regions. REST-VP16 binds to the same RE1/NRSE, but activates these REST/NRSF target genes. However, it is unclear whether REST-VP16 expression is sufficient to cause formation of functional neurons either from neural stem cells or from heterologous stem cells. Here we show that the expression of REST-VP16 in myoblasts grown under muscle differentiation conditions blocked entry into the muscle differentiation pathway, countered endogenous REST/NRSF-dependent repression, activated the REST/NRSF target …

Depressed Type 1 Cytokine Synthesis By Superantigen-Activated Cd4+ T Cells Of Women With Human Papillomavirus-Related High-Grade Squamous Intraepithelial Lesions, Bang-Ning Lee, Michele Follen, De-Yu Shen, Anais Malpica, Karen Adler-Storthz, William T. Shearer, James M. Reuben

Faculty, Staff and Student Publications

Carcinoma of the cervix is causally related to infection with the human papillomavirus (HPV), and T cells play a pivotal role in the immune response of the host to rid itself of HPV infection. Therefore, we assessed the T-cell function of women with HPV-related cervical neoplasia against a superantigen, Staphylococcus enterotoxin B (SEB). Each woman provided a cervical brush specimen for HPV DNA testing and Papanicolaou (Pap) smears for the staging of cervical lesions. They also provided a blood specimen for determination of the ability of CD4(+) T and CD8(+) T cells to synthesize Th1 (interleukin-2 [IL-2], gamma interferon [IFN-gamma], …

Cognitive Impact Of Interactive Multimedia, Yanko F. Michea,

Dissertations and Theses (Open Access)

Technology has been gradually introduced in heath education. One of the most attractive features of this technology-based education is the use of multimedia. In this article we explore the research evidence about the role that multimedia is playing in education. From that analysis we describe the most relevant features of this technology to prepare a common ground of discussion about the evaluation of its impact on educational outcomes. As part of this analysis, we organize current research evidence on the use of technology in medical education, distinguishing diverse variables involved in the process, like knowledge (declarative, procedural), learner characteristics, curricular …

Evaluating The Disparity Of Female Breast Cancer Mortality Among Racial Groups - A Spatiotemporal Analysis, Chiehwen E. Hsu, Holly Jacobson, Francisco Soto Mas

Faculty, Staff and Student Publications

Background The literature suggests that the distribution of female breast cancer mortality demonstrates spatial concentration. There remains a lack of studies on how the mortality burden may impact racial groups across space and over time. The present study evaluated the geographic variations in breast cancer mortality in Texas females according to three predominant racial groups (non-Hispanic White, Black, and Hispanic females) over a twelve-year period. It sought to clarify whether the spatiotemporal trend might place an uneven burden on particular racial groups, and whether the excess trend has persisted into the current decade.

Methods The Spatial Scan Statistic was employed …

Detecting Spatiotemporal Clusters Of Accidental Poisoning Mortality Among Texas Counties, Us, 1980 – 2001, Ella T. Nkhoma, Chiehwen E. Hsu, Victoria I. Hunt, Ann M. Harris

Faculty, Staff and Student Publications

Background Accidental poisoning is one of the leading causes of injury in the United States, second only to motor vehicle accidents. According to the Centers for Disease Control and Prevention, the rates of accidental poisoning mortality have been increasing in the past fourteen years nationally. In Texas, mortality rates from accidental poisoning have mirrored national trends, increasing linearly from 1981 to 2001. The purpose of this study was to determine if there are spatiotemporal clusters of accidental poisoning mortality among Texas counties, and if so, whether there are variations in clustering and risk according to gender and race/ethnicity. The Spatial …

Noninvasive Assessment Of Diffusion Hypoxia Following Administration Of Nitrous Oxide-Oxygen, Arthur H. Jeske, Clark W. Whitmire, Chris Freels, Mike Fuentes

Faculty, Staff and Student Publications

The phenomenon of diffusion hypoxia is commonly believed to occur unless nitrous oxide-oxygen inhalation sedation is followed by "washout" with 100% oxygen for 5 minutes upon termination of the flow of nitrous oxide. When systematically studied, however, this phenomenon generally appears to be unfounded. The present study evaluated the effect of breathing room air instead of 100% oxygen in healthy (ASA 1) human volunteers following administration of sedative concentrations of nitrous oxide. The occurrence of hypoxia was determined objectively, using pulse oximetry and a standardized psychomotor skills test (Trieger test). Diffusion hypoxia was not observed using these criteria.

In Vitro Analog Of Classical Conditioning Of Feeding Behavior In Aplysia, Riccardo Mozzachiodi, Hilde A. Lechner, Douglas A. Baxter, John H. Byrne

Faculty, Staff and Student Publications

The feeding behavior of Aplysia californica can be classically conditioned using tactile stimulation of the lips as a conditioned stimulus (CS) and food as an unconditioned stimulus (US). Moreover, several neural correlates of classical conditioning have been identified. The present study extended previous work by developing an in vitro analog of classical conditioning and by investigating pairing-specific changes in neuronal and synaptic properties. The preparation consisted of the isolated cerebral and buccal ganglia. Electrical stimulation of a lip nerve (AT4) and a branch of the esophageal nerve (En2) served as the CS and US, respectively. Three protocols were used: paired, …

Ms211: Albina Personal Statement, Armin Weinberg

Works on Radiation Effects: 1990-2020

This is a personal statement written by Albina Orazgaliyeva (now Rippy). She was the daughter of our colleague (Marina) in Semipalatinsk who we helped come to the US to study. She eventually graduated from UH, married, and built a very successful business that they sold called Yoga One. The statement however is a powerful reminder of the reach of the partnership that went well beyond our funded mandate to that of friendship. Her family built a very successful private pharmacy and production business at a time when almost none existed after the breakup of the Soviet Union left countries like …

Rifn-Gamma-Mediated Growth Suppression Of Platinum-Sensitive And -Resistant Ovarian Tumor Cell Lines Not Dependent Upon Arginase Inhibition, Bohuslav Melichar, Wei Hu, Rebecca Patenia, Karolina Melicharová, Stacie T Gallardo, Ralph Freedman

Faculty, Staff and Student Publications

BACKGROUND: Arginine metabolism in tumor cell lines can be influenced by various cytokines, including recombinant human interferon-gamma (rIFN-gamma), a cytokine that shows promising clinical activity in epithelial ovarian cancer (EOC). METHODS: We examined EOC cell lines for the expression of arginase in an enzymatic assay and for transcripts of arginase I and II, inducible nitric oxide synthase (iNOS), and indoleamine 2,3-dioxygenase (IDO) by reverse transcription-polymerase chain reaction. The effects of rIFN-gamma on arginase activity and on tumor cell growth inhibition were determined by measuring [3H]thymidine uptake. RESULTS: Elevated arginase activity was detected in 5 of 8 tumor cell lines, and …
