Acetaminophen: Beyond Pain And Fever-Relieving, Eric R. Blough, Miaozong Wu

MIIR Faculty Research

Acetaminophen, also known as APAP or paracetamol, is one of the most widely used analgesics (pain reliever) and antipyretics (fever reducer). According to the U.S. Food and Drug Administration, currently there are 235 approved prescription and over-the-counter drug products containing acetaminophen as an active ingredient. When used as directed, acetaminophen is very safe and effective; however when taken in excess or ingested with alcohol hepatotoxicity and irreversible liver damage can arise. In addition to well known use pain relief and fever reduction, recent laboratory and pre-clinical studies have demonstrated that acetaminophen may also have beneficial effects on blood glucose levels, …

Interferons As Therapeutic Agents In Infectious Diseases, Mckenzie C. Ferguson, Scott Bergman, Cathy Santanello

Pharmacy Faculty Research, Scholarship, and Creative Activity

This article explains the rationale for development of interferons as therapeutic agents, and describes commercial products available today. It also provides a summary of studies that have been performed with interferons for use as exogenous biological response modifiers in viral infections. Overall, the best data exist for treatment of viral hepatitis B and C, for which interferons are a cornerstone of therapy. Although infections with human papillomavirus and common cold viruses sometimes respond favorably to interferons, their outcomes are far from ideal. Finally, the role of interferons as vaccine adjuvants is still being explored but could be promising.

Work Placement Blogs To Harness Diverse Learning Experiences And Foster A Community Of Practice, Julie Dunne

Conference papers

Students on work placement will have very different experiences from each other, however they are generally not connected to their peers, but working with professionals under the guidance of a college tutor. Therefore during placement they are not formally supported by peers and cannot learn from the diverse range of activities their peers will experience. An active learning community and a sense of connectedness to others are critical to real learning (LaPointe, 2008), while learning through participation in a community of practice involves sharing experiences and discovering how to improve by regularly interacting with peers (Wenger, 2002). The aim of …

A Model Of Intracellular Θ Phase Precession Dependent On Intrinsic Subthreshold Membrane Currents., L Stan Leung

Physiology and Pharmacology Publications

A hippocampal place cell fires at an increasingly earlier phase in relation to the extracellular theta rhythm as a rodent moves through the place field. The present report presents a compartment model of a CA1 pyramidal cell that explains the increase in amplitude and the phase precession of intracellular theta oscillations, with the assumption that the cell receives an asymmetric ramp depolarization (<10 >mV) in the place field and rhythmic inhibitory and/or excitatory synaptic driving. Intracellular subthreshold membrane potential oscillations (MPOs) increase in amplitude and frequency, and show phase precession within the place field. Theta phase precession and MPO power …

Histone Deacetylase Inhibitors And Mithramycin A Impact A Similar Neuroprotective Pathway At A Crossroad Between Cancer And Neurodegeneration, Sama F. Sleiman, Jill Berlin, Manuela Basso, Saravanan S. Karuppagounder, Jürgen Rohr, Rajiv R. Ratan

Pharmaceutical Sciences Faculty Publications

Mithramycin A (MTM) and histone deacetylase inhibitors (HDACi) are effective therapeutic agents for cancer and neurodegenerative diseases. MTM is a FDA approved aureolic acid-type antibiotic that binds to GC-rich DNA sequences and interferes with Sp1 transcription factor binding to its target sites (GC box). HDACi, on the other hand, modulate the activity of class I and II histone deacetylases. They mediate their protective function, in part, by regulating the acetylation status of histones or transcription factors, including Sp1, and in turn chromatin accessibility to the transcriptional machinery. Because these two classes of structurally and functionally diverse compounds mediate similar therapeutic …

Effect Of Combined Oral Contraceptives On Insulin Clearance In Lean And Obese Pre-Menopausal Women, Vidya Moorthy

Theses and Dissertations

Introduction: Obese women are predisposed to greater risks of insulin resistance and compensatory hyperinsulinemia. Likewise, African-Americans, appear to be inherently insulin resistant and hyperinsulinemic even after controlling for obesity. Hyperinsulinemia has been attributed to insulin resistance and a compensatory insulin hyper-secretion by the pancreas, as well as decreased insulin clearance, notably in obesity. Pharmacological agents that may worsen insulin resistance/hyperinsulinemia in obese women is of clinical relevance. Previous data from our group suggested that combined oral contraceptives (COCs) may worsen insulin sensitivity particularly in obese women, but limited information on insulin clearance is available in obese women or African-American women. …
