MicroRNAs (miRNAs) are short 19- to 24-nt RNA molecules that have been shown to regulate the expression of other genes in a variety of eukaryotic systems. Abnormal expression of miRNAs has been observed in several human cancers, and furthermore, germ-line and somatic mutations in human miRNAs were recently identified in patients with chronic lymphocytic leukemia. Thus, human miRNAs can act as tumor suppressor genes or oncogenes, where mutations, deletions, or amplifications can underlie the development of certain types of leukemia. In addition, previous studies have shown that miRNA expression profiles can distinguish among human solid tumors from different organs. Because …


Dynamics Of A Minimal Model Of Interlocked Positive And Negative Feedback Loops Of Transcriptional Regulation By Camp-Response Element Binding Proteins, Hao Song, Paul Smolen, Evyatar Av-Ron, Douglas A Baxter, John H Byrne May 2007

Dynamics Of A Minimal Model Of Interlocked Positive And Negative Feedback Loops Of Transcriptional Regulation By Camp-Response Element Binding Proteins, Hao Song, Paul Smolen, Evyatar Av-Ron, Douglas A Baxter, John H Byrne

Faculty, Staff and Student Publications

cAMP-response element binding (CREB) proteins are involved in transcriptional regulation in a number of cellular processes (e.g., neural plasticity and circadian rhythms). The CREB family contains activators and repressors that may interact through positive and negative feedback loops. These loops can be generated by auto- and cross-regulation of expression of CREB proteins, via CRE elements in or near their genes. Experiments suggest that such feedback loops may operate in several systems (e.g., Aplysia and rat). To understand the functional implications of such feedback loops, which are interlocked via cross-regulation of transcription, a minimal model with a positive and negative loop …

Using Gis-Based Methods Of Multicriteria Analysis To Construct Socio-Economic Deprivation Indices, Nathaniel Bell, Nadine Schuurman, Michael V. Hayes May 2007

Using Gis-Based Methods Of Multicriteria Analysis To Construct Socio-Economic Deprivation Indices, Nathaniel Bell, Nadine Schuurman, Michael V. Hayes

Faculty Publications

BACKGROUND: Over the past several decades researchers have produced substantial evidence of a social gradient in a variety of health outcomes, rising from systematic differences in income, education, employment conditions, and family dynamics within the population. Social gradients in health are measured using deprivation indices, which are typically constructed from aggregated socio-economic data taken from the national census--a technique which dates back at least until the early 1970's. The primary method of index construction over the last decade has been a Principal Component Analysis. Seldom are the indices constructed from survey-based data sources due to the inherent difficulty in validating …


The Pseudomonas Aeruginosa Secreted Protein Pa2934 Decreases Apical Membrane Expression Of The Cystic Fibrosis Transmembrane Conductance Regulator, Daniel P. Maceachran, Siying Ye, Jennifer M. Bomberger, Deborah A. Hogan, Agnieszka Swiatecka-Urban, Bruce Stanton, George A. O'Toole May 2007

The Pseudomonas Aeruginosa Secreted Protein Pa2934 Decreases Apical Membrane Expression Of The Cystic Fibrosis Transmembrane Conductance Regulator, Daniel P. Maceachran, Siying Ye, Jennifer M. Bomberger, Deborah A. Hogan, Agnieszka Swiatecka-Urban, Bruce Stanton, George A. O'Toole

Dartmouth Scholarship

We previously reported that Pseudomonas aeruginosa PA14 secretes a protein that can reduce the apical membrane expression of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Here we report that we have used a proteomic approach to identify this secreted protein as PA2934 [corrected], and we have named the gene cif, for CFTR inhibitory factor. We demonstrate that Cif is a secreted protein and is found associated with outer membrane-derived vesicles. Expression of Cif in Escherichia coli and purification of the C-terminal six-His-tagged Cif protein showed that Cif is necessary and sufficient to mediate the reduction in apical membrane expression …


Clinical Presentation And Genotype Of Hepatitis Delta In Karachi, Tariq Moatter, Zaigham Abbas, Sabhita Shabir, Wasim Jafri May 2007

Clinical Presentation And Genotype Of Hepatitis Delta In Karachi, Tariq Moatter, Zaigham Abbas, Sabhita Shabir, Wasim Jafri

Department of Pathology and Laboratory Medicine

Aim:
To assess the clinical presentation and genotypes of delta hepatitis in local population.
Methods:
In this prospective study, 39 consecutive patients who were positive for HBsAg and hepatitis D virus (HDV) antibody were included. The patients were divided in two groups on the basis of presence or absence of HDV RNA and a comparative study was done. Genotype of HDV was determined in PCR positive patients.
Results:
Overall there is male dominance, in which 34 patients out of 39 (87.2%) were male. Twenty (51%) patients were from the adjacent areas of three provinces; Sindh, Punjab and Balochistan indicating the …

Chronic Administration Of Methylphenidate Produces Neurophysiological And Behavioral Sensitization, Pamela B Yang, Alan C Swann, Nachum Dafny May 2007

Chronic Administration Of Methylphenidate Produces Neurophysiological And Behavioral Sensitization, Pamela B Yang, Alan C Swann, Nachum Dafny

Faculty, Staff and Student Publications

The electrophysiological properties of acute and chronic methylphenidate (MPD) on neurons of the prefrontal cortex (PFC) and caudate nucleus (CN) have not been studied in awake, freely behaving animals. The present study was designed to investigate the dose-response effects of MPD on sensory evoked potentials recorded from the PFC and CN in freely behaving rats previously implanted with permanent electrodes, as well as their behavioral (locomotor) activities. On experimental day 1, locomotor behavior of rats was recorded for 2 h post-saline injection, and sensory evoked field potentials were recorded before and after saline and 0.6, 2.5, and 10 mg/kg, i.p., …


Co-Localization Of P-Creb And P-Nr1 In Spinothalamic Neurons In A Chronic Muscle Pain Model, Marie K. Hoeger Bement, Kathleen A. Sluka May 2007

Co-Localization Of P-Creb And P-Nr1 In Spinothalamic Neurons In A Chronic Muscle Pain Model, Marie K. Hoeger Bement, Kathleen A. Sluka

Physical Therapy Faculty Research and Publications

Activation of the cAMP pathway is an important mediator of chronic muscle pain. This study examined phosphorylation of the transcription factor cAMP-response-element-binding protein (p-CREB) and the NR1 subunit of the NMDA receptor (p-NR1) in the spinal cord. Bilateral mechanical hyperalgesia of the paw was induced by administering two injections of acidic saline, 5 days apart, into the gastrocnemius muscle of male Sprague–Dawley rats. The proportion of spinothalamic neurons that expressed p-NR1 or p-CREB did not change in the dorsal horn 24 h after the second intramuscular acid injection compared with animals that received pH 7.2 injections. This lack of change …

The Prescription Drug Safety Net: Access To Pharmaceuticals For The Uninsured, Jack Hoadley May 2007

The Prescription Drug Safety Net: Access To Pharmaceuticals For The Uninsured, Jack Hoadley

National Health Policy Forum

This background paper provides an overview of organized programs that provide access to prescription drug products for uninsured persons, with an emphasis on manufacturer-sponsored pharmacy assistance programs (PAPs) and the federal 340B drug pricing program. It summarizes the chief characteristics of these programs and reviews concerns regarding the reach and efficiency of these efforts. The paper begins with a brief examination of the number of people who lack insurance coverage for prescription drugs and discusses the influence of this gap in coverage on health status. The paper also describes informal mechanisms providers frequently use to help uninsured patients fill their …
