Asthma Knowledge, Adherence, And Administration Techniques In Hispanic Caregivers Of Pediatrics, Joshua Arnold, Rachel Culp, Kyle Hultz, Benjamin Robertson, Jon Wilkie, Amy Wuobio, Marty L. Eng, Kelly J. Hiteshew

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

7.5% of Hispanics in the United States suffer from asthma-related diseases, and Latino children are not as likely to use preventative asthma medications as compared with Caucasians. Educational interventions may reduce the number of visits to emergency-care. The reasons for non-adherence are currently unknown, and discovering these reasons will help to address the problem.

Anabolic And Androgenic Effects Of Certain Atriplex Species Grown In Egypt, Dina M. El-Kersh, Fatma S. El-Sakhawy, Dina R. Abou-Hussein, Amany A. Sleem

Pharmacy

20-Hydroxyecdysone (20-HE) was detected by TLC in the ethyl acetate fraction of two Atriplex species grown in Egypt: A. lindleyi subsp. inflata and A. leucoclada. EIA quantification of 20-HE proved its presence in a concentration of 9.15 and 7.3 μg/g dried aerial parts in each of the two species, respectively. Significant anabolic and androgenic activities were demonstrated for 20-HE comparing to testosterone; the study also revealed that the total alcohol extract and the ethyl acetate fraction of A. lindleyi subsp. inflata exhibited greater activities than their analogues in A. leucoclada. Column chromatographic fractionation of the ethyl acetate fraction of the …

A Human Phospholipid Phosphatase Activated By A Transmembrane Control Module, Christian R. Halaszovich, Michael G. Leitner, Angeliki Mavrantoni, Audrey Le, Ludivine Frezza, Anja Feuer, Daniela N. Schreiber, Carlos A. Villalba-Galea, Dominik Oliver

School of Pharmacy Faculty Articles

In voltage-sensitive phosphatases (VSPs), a transmembrane voltage sensor domain (VSD) controls an intracellular phosphoinositide phosphatase domain, thereby enabling immediate initiation of intracellular signals by membrane depolarization. The existence of such a mechanism in mammals has remained elusive, despite the presence of VSP-homologous proteins in mammalian cells, in particular in sperm precursor cells. Here we demonstrate activation of a human VSP (hVSP1/TPIP) by an intramolecular switch. By engineering a chimeric hVSP1 with enhanced plasma membrane targeting containing the VSD of a prototypic invertebrate VSP, we show that hVSP1 is a phosphoinositide-5-phosphatase whose predominant substrate is PI(4,5)P(2). In the chimera, enzymatic activity …

A Review Of Literature Regarding North American Parent’S Perceptions About The Hpv Vaccine And The Effect They Have On Vaccine Uptake In Their Adolescent Daughters Ages 9 To 26, Francesca Couser, Jessica Dahnke

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

A woman dies every 2 minutes due to HPV related illness. Cervical cancer is the 5th most common cancer worldwide, with approximately 471,000 new cases diagnosed each year. There is a decreased risk of HPV related illnesses with vaccine development. However, lack of uptake is suspected to be impacted by parental knowledge deficit. Previously, these illnesses received little attention by parents and healthcare providers, even with the very evident increase in newly diagnosed patients. Without education, rate of infection will continue to increase as vaccine uptake remains stagnant. The purpose of this study is to determine how education from healthcare …

A Comparison Of The Effect Of Intermittent And Continuous Infusion Of Meropenem On The Prevalence Of Nausea In Pediatric Cystic Fibrosis Patients, Marissa Cushing, Juanita A. Draime, Bao-Ngoc Ho, Jordan Nicholls, Bethany Sibbitt, Rebecca Widder, Rebecca J. Gryka, Denise S. Simpson

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

Cystic Fibrosis (CF) is a genetic disease, leading to changes of membrane secretions causing obstruction of smaller airways. CF patients often develop pulmonary infections and require antibiotic treatment. Meropenem is a broad spectrum beta lactam that acts by lysing microbes through interfering with bacterial cell wall synthesis. Although a safe and effective treatment, data on pediatric patients is limited.

Edible Marijuana: A New Frontier In The Culinary World, Ariella H. Wolkowicz

Honors Theses - Providence Campus

Cannabis, commonly known as marijuana, has a rich history as a source of fiber, food and medicine (Li 437). Since 1785, physicians and scientists alike have worked to discover the active chemical components and medical effectiveness of this plant (Touw 2; Aldrich). Despite its complicated legal history, marijuana has retained a place culturally and, in some countries, scientifically as an effective medical agent. As a medically edible ingredient, cannabis has also been more recently heralded as a new, even cutting edge flavor, opening a new frontier to the culinary community.

After the isolation of the main active ingredient in cannabis, …

Pediatric Pharmacogenomics: A Systematic Assessment Of Ontogeny And Genetic Variation To Guide The Design Of Statin Studies In Children., Jonathan B. Wagner, J Steven Leeder

Manuscripts, Articles, Book Chapters and Other Papers

The dose-exposure-response relationship for drugs may differ in pediatric patients compared with adults. Many clinical studies have established drug dose-exposure relationships across the pediatric age spectrum; however, genetic variation was seldom included. This article applies a systematic approach to determine the relative contribution of development and genetic variation on drug disposition and response using HMG-CoA reductase inhibitors as a model. Application of the approach drives the collection of information relevant to understanding the potential contribution of ontogeny and genetic variation to statin dose-exposure-response in children, and identifies important knowledge deficits to be addressed through the design of future studies.

Drug–Drug Conditioning Between Citalopram And Haloperidol Or Olanzapine In A Conditioned Avoidance Response Model: Implications For Polypharmacy In Schizophrenia, Nathan L. Sparkman, Ming Li

Department of Psychology: Faculty Publications

Patients with schizophrenia often have anxiety and depression, and thus are treated with multiple psychotherapeutic medications. This practice of polypharmacy increases the possibility for drug–drug interactions. However, the pharmacological and behavioral mechanisms underlying drug–drug interactions in schizophrenia remain poorly understood. In the present study, we adopted a preclinical approach and examined a less known behavioral mechanism, drug–drug conditioning (DDC) between haloperidol (a typical antipsychotic) or olanzapine (atypical antipsychotic) and citalopram (a selective serotonin reuptake inhibitor). A rat two-way conditioned avoidance response paradigm was used to measure antipsychotic activity and determine how DDC may alter the antipsychotic efficacy in this model. …

Situation Analysis Of Child Labour In Karachi, Pakistan: A Qualitative Study, Asaad Ahmed Nafees, Kausar S. Khan, Zafar Fatmi, Mubashir Aslam

Community Health Sciences

In Karachi, large employment opportunities, burgeoning population and the availability of cheap labour might be the contributing factors for the increasing prevalence of child labour. A literature review was conducted in 2007 that included published and unpublished literature since 2000. Various organizations working in the field were also covered, while the perception of the child labourers was covered through three focus group discussions. Common health issues among the child labourers in Karachi included respiratory illnesses, fever and generalised pains, as well as drug and sexual abuse. Organisations working for child labour could be broadly categorised into those working for legal …

Vaccines represent the most important medical advance of the twentieth century. The time has passed when large numbers of children and adults suffered serious, life threatening illness from viruses including poliovirus, measles virus, influenza viruses, hepatitis B virus and varicella zoster virus or faced lifelong disability or death from bacterial infections including Hemophilus influenzae, meningococcus and pneumococcus, all infections that can be prevented now by effective vaccines.

Voltage-Controlled Enzymes: The New Janus Bifrons, Carlos A. Villalba-Galea

School of Pharmacy Faculty Articles

The Ciona intestinalis voltage-sensitive phosphatase, Ci-VSP, was the first Voltage-controlled Enzyme (VEnz) proven to be under direct command of the membrane potential. The discovery of Ci-VSP conjugated voltage sensitivity and enzymatic activity in a single protein. These two facets of Ci-VSP activity have provided a unique model for studying how membrane potential is sensed by proteins and a novel mechanism for control of enzymatic activity. These facets make Ci-VSP a fascinating and versatile enzyme. Ci-VSP has a voltage sensing domain (VSD) that resembles those found in voltage-gated channels (VGC). The VSD resides in the N-terminus and is formed by four …

Key Players In Reverse Cholesterol Transport: The Plasma Enzyme Lcat, Christopher J. Pechura

Undergraduate Research Posters 2012

Lecithin cholesterol acyltransferase (LCAT) is a plasma enzyme that remodels nascent high density lipoprotein (HDL) into a mature form called spherical HDL. The model will be used in the future to map the amino acid residues from LCAT and the protein component of nascent HDL (apoA1) involved in mutual interaction, and to identify LCAT residues interacting with the lipid phase of nascent HDL.

Biological Evaluation Of Cyclooxygenase-2 Inhibitor Nimesulide Derivatives As Anti-Agents, Amandeep Singh, Snigdha Chennamaneni

Undergraduate Research Posters 2012

Cyclooxygenase-2 (COX-2) inhibitor nimesulide inhibits the proliferation of various types of cancer cells mainly via COX-2 independent mechanisms, which makes it a good lead compound for anti-cancer drug development. A series of new nimesulide analogs were evaluated with cell proliferation assay based on a non-small lung cancer cell line H292. The results showed that several derivatives were very active to against H292 cell growth with IC50s of sub nano mole. These results suggest the possibility of using these nimesulide derivatives as chemo preventive agents.

Borrelia Burgdorferi Cp32 Bpab Modulates Expression Of The Prophage Nucp Nuclease And Ssbp Single-Stranded Dna-Binding Protein, Alicia M. Chenail, Brandon L. Jutras, Claire A. Adams, Logan H. Burns, Amy Bowman, Ashutosh Verma, Brian Stevenson

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The Borrelia burgdorferi BpaB proteins of the spirochete's ubiquitous cp32 prophages are DNA-binding proteins, required both for maintenance of the bacteriophage episomes and for transcriptional regulation of the cp32 erp operons. Through use of DNase I footprinting, we demonstrate that BpaB binds the erp operator initially at the sequence 5′-TTATA-3′. Electrophoretic mobility shift assays indicated that BpaB also binds with high affinity to sites located in the 5′ noncoding regions of two additional cp32 genes. Characterization of the proteins encoded by those genes indicated that they are a single-stranded DNA-binding protein and a nuclease, which we named SsbP and NucP, …

Human Endometrial Stromal Stem Cells Differentiate Into Megakaryocytes With The Ability To Produce Functional Platelets, Jinju Wang, Shuzhen Chen, Cheng Zhang, Samantha Stegeman, Teresa Pfaff-Amesse, Ying Zhang, Wenfeng Zhang, Lawrence Amesse, Yanfang Chen

Pharmacology and Toxicology Faculty Publications

Human endometrium is a high dynamic tissue that contains endometrial stromal stem cells (hESSCs). The hESSCs have been differentiated into a number of cell lineages. However, differentiation of hESSCs into megakaryocytes (MKs) has not yet been investigated. The aim of this study was to investigate the feasibility of MK generation from hESSCs and subsequent production of functional platelets (PLTs). In our study, hESSCs were cultured from endometrial stromal cells as confirmed by positive stromal cell specific markers (CD90 and CD29) and negative hematopoietic stem cell markers (CD45 and CD34) expression. Then, hESSCs were differentiated in a medium supplemented with thrombopoietin …
