Analysis And Fingerprinting Of Glycosaminoglycans, Joseph King

Theses and Dissertations

Heparin is a complex mixture of sulfated polysaccharides derived from animals and one of the oldest drugs in use. While an efficacious anticoagulant, heparin is beset by side effects and pharmacokinetic difficulties. Low molecular weight heparins (LMWH) are made by depolymerizing unfractionated heparin (UFH) and present improvements in these areas. However, they still retain a phenomenally high level of complexity due to their polydispersity and the introduction of non-native structural features. This makes the structural characterization LMWHs a daunting task. This work details the development of a novel capillary electrophoretic (CE) method for fingerprinting LMWHs. Since their complexity normally results …

Synthesis Of A Library Of Sulfated Small Molecules, Shrenik Mehta

Theses and Dissertations

The discovery of heparin in 1916 resulted in a huge impact on the practice of medicine. Heparin has played a major role in alleviating thrombotic disorders and has also exhibited effects on almost every major system in the human body. Over the past few decades, more and more heparin-protein interactions have come to light. It is implicated to modulate several important processes such as cell growth and differentiation, inflammatory response, viral infection mechanism etc. More interesting is the observation that these interactions are considerably specific with regard to oligosaccharide sequences which have specific spatially oriented sulfate groups modulating the responses. …

Antivirulence Potential Of Tr-700 And Clindamycin On Clinical Isolates Of Staphylococcus Aureus Producing Phenol-Soluble Modulins, Jason Yamaki, Timothy Synold, Annie Wong-Beringer

Pharmacy Faculty Articles and Research

Staphylococcus aureus strains (n = 50) causing complicated skin and skin structure infections produced various levels of phenol-soluble modulin alpha-type (PSMα) peptides; some produced more than twice that produced by the control strain (LAC USA300). TR-700 (oxazolidinone) and clindamycin strongly inhibited PSM production at one-half the MIC but exhibited weak to modest induction at one-fourth and one-eighth the MICs, primarily in low producers. Adequate dosing of these agents is emphasized to minimize the potential for paradoxical induction of virulence.

Physiology and Pharmacology Publications

BACKGROUND: Immuno-modulatory effects of ginseng, including both immuno-stimulatory and immuno-suppressive effects, have been widely reported. This study aims to determine whether the paradoxical immuno-modulatory effect is related to unique phytochemical profiles of different North American (NA) ginseng, namely aqueous (AQ) and alcoholic (ALC) extracts.

METHODS: AQ and ALC extracts were prepared and their immuno-bioactivity were studied in vitro in murine macrophages (Raw 264.7) through measuring the direct stimulatory production of pro-inflammatory mediator and cytokines as well as the suppression of lipopolysaccharide (LPS)-stimulatory response by the two extracts. Gel permeation chromatography was used to fractionate and isolate phytochemicals for characterization of …

Controlling The Activity Of A Phosphatase And Tensin Homolog (Pten) By Membrane Potential, Jérôme J. Lacroix, Christian R. Halaszovich, Daniela N. Schreiber, Michael G. Leitner, Francisco Bezanilla, Dominik Oliver, Carlos A. Villalba-Galea

School of Pharmacy Faculty Articles

The recently discovered voltage-sensitive phosphatases (VSPs) hydrolyze phosphoinositides upon depolarization of the membrane potential, thus representing a novel principle for the transduction of electrical activity into biochemical signals. Here, we demonstrate the possibility to confer voltage sensitivity to cytosolic enzymes. By fusing the tumor suppressor PTEN to the voltage sensor of the prototypic VSP from Ciona intestinalis, Ci-VSP, we generated chimeric proteins that are voltage-sensitive and display PTEN-like enzymatic activity in a strictly depolarization-dependent manner in vivo. Functional coupling of the exogenous enzymatic activity to the voltage sensor is mediated by a phospholipid-binding motif at the interface between voltage sensor …

Pharmacist Perception Of Opioid Overuse For Analgesia In The Retail Setting, Kenneth Jacob Craig, Josh Winebough

Undergraduate Honors Thesis Collection

Opioid analgesics are a class of medications with affinity for receptors in the brain which are naturally targeted by endogenous opioid peptides to exert neuromodulatory action.' Long before this target pathway was ever elucidated, ancient cultures had documented use of a naturally occurring plant derivative, opium, which provided the same effects as opioid drugs today. The active alkaloid constituent of opium is morphine. The human body's equivalents of these substrates interact with multiple types of opioid receptors which produce the effects responsible for pain relief. In addition, there are also unwanted side effects including constipation, nemesis, and respiratory depression. Contributing …

Analysis Of Oocyte-Like Cells Differentiated From Porcine Fetal Skin-Derived Stem Cells, Paul W. Dyce, Wei Shen, Evanna Huynh, Hua Shao, Daniel A. F. Villagómez, Gerald M. Kidder, W. Allan King, Julang Li

Physiology and Pharmacology Publications

We previously reported the differentiation of cells derived from porcine female fetal skin into cells resembling germ cells and oocytes. A subpopulation of these cells expressed germ cell markers and formed aggregates resembling cumulus-oocyte complexes. Some of these aggregates extruded large oocyte-like cells (OLCs) that expressed markers consistent with those of oocytes. The objective of the current study was to further characterize OLCs differentiated from porcine skin-derived stem cells. Reverse transcriptase (RT)-polymerase chain reaction and Western blot revealed the expression of connexin37 and connexin43, both of which are characteristic of ovarian follicles. The expression of meiosis markers DMC1 and synaptonemal …
