Archaeosomes And Tetraether Lipid Liposome, Hans-Joachim Freisleben

Majalah Ilmu Kefarmasian

Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up the majority of total membrane lipids. Archaeal lipids are able to form stable liposomal structures, both from membrane factions, mainly the polar membrane fraction, i.e. archaeosomes, or from highly purified TEL (tetraether lipid liposomes). Liposomes of the main polar lipid (MPL) from thermoacidophilic archaeon Ihermoplasma acidophilum were thoroughly inevstigated. Archaeosomes and TEL liposomes exhibit extremely low proton permeability and high stability at …

Therapeutic Drug Monitoring Of Factor Viii Prophylaxis Using Its Plasma Coagulant Activity And Global Hemostasis Biomarkers: A Pharmacokinetic/Pharmacodynamic Pilot Study, Hawaj Maitham Al

Theses and Dissertations

Background: The current clinical practice of factor VIII (FVIII) prophylaxis revolves around converting patients with severe hemophilia A, hereafter simply referred to as hemophilia, phenotype (defined as plasma factor VIII coagulant activity [FVIII:C] <1 IU dL-1) to moderate hemophilia phenotype (defined as plasma FVIII:C from 1–5 IU dL-1). However, a wide inter-individual variation in bleeding tendency is observed despite changes in plasma FVIII:C (pharmacokinetic [PK] changes). Therefore, monitoring FVIII prophylaxis by global hemostasis biomarkers (pharmacodynamic [PD] response) can potentially be beneficial. Objective: To conduct appropriate PK/PD modeling using plasma FVIII:C and global hemostasis (platelet function and blood viscoelastic) biomarkers in severe hemophilia. Methods: Nine non-bleeding severe hemophiliacs (plasma FVIII:C <1 IU dL-1) with variant bleeding tendency (5 frequent bleeders and 4 infrequent bleeders) were infused with a recombinant factor FVIII (rFVIII) prophylactic dose (mean = 32.1 international units per kilogram [IU kg-1]). Blood was collected at baseline and 0.5-, 1-, 2-, 4-, 8-, 12-, 24- and 48-hours (h) post-dose for plasma FVIII:C, platelet function (platelet contractile force [PCF], clot elastic modulus [CEM] and force onset time [FOT]) and blood viscoelastic (reaction-time [R], kinetics-time [K] and maximum amplitude [MA]) biomarkers and activated partial thromboplastin time (aPTT). Non-compartmental analysis (NCA) was performed using standard methods. Compartmental analysis (CA) and PK/PD modeling were performed by non-linear regression. Correlation and analysis of variance (ANOVA) were used to explore the role of clinically relevant modifiers of bleeding tendency, as appropriate. ANOVA was used to assess inter-group differences in pertinent PK and PD parameters. P value <0.05 significance level was pre-specified for all statistical tests. Results: Mean (±SD) volume of distribution at steady state (Vss), total clearance (CLtot) and terminal half-life (t1/2) from NCA were 40.5 (±11.2) milliliter per kilogram (mL kg-1), 2.9 (±1.2) milliliter per hour per kilogram (mL h-1 kg-1) and 11.6 (±6.2) h, respectively. Mean (±SD) Vss and CLtot from the one-compartment body model (CA) were 39.6 (±8.9) mL kg-1 and 3.1 (±1.3) mL h-1 kg-1, respectively. The mean (±SD) baseline effect (E0) and slope from the PK/PD linear modeling were: for aPTT, 48.9 (±4.4) seconds (sec) and -0.025 (±0.009) second deciliter per international unit (sec dL IU-1), respectively; for PCF, 0.3 (±0.3) kilodynes (kdynes) and 0.008 (±0.004) kilodynes deciliter per international unit (kdynes dL IU-1), respectively; and for CEM, 0.0 (±0.0) kilodynes per square centimeter (kdynes cm-2) and 0.032 (±0.016) kilodynes deciliter per international unit per square centimeter (kdynes dL IU-1 cm-2), respectively. The mean (±SD) maximum effect (Emax) and half the maximum effective concentration (EC50) from the PK/PD sigmoidal Emax model were: for FOT, 70.1 (±16.9) % reduction and 87.8 (±31.4) IU dL-1 for FOT, respectively; for R, 74.9 (±26.0) % reduction and 68.5 (±28.4) IU dL-1, respectively; and for K, 73.2 (±36.4) % reduction and 67.2 (±29.0) IU dL-1, respectively. MA was not PK/PD modeled due to its low sensitivity. Conclusions: Plasma FVIII:C remained ≥1 IU dL-1 over the prophylactic interval. FOT and R were the most sensitive biomarkers at lower plasma FVIII:C. PCF and CEM were more sensitive than K and aPTT at lower plasma FVIII:C. MA was the least sensitive biomarker. Correlation and inter-group differences did not reach statistical significance (small sample size). These results may be used to assess risk of bleeding and dose-optimize FVIII prophylaxis in severe hemophilia.

Quantitative Analysis Of Multiple Charged Large Molecules In Human Or Rat Plasma Using Liquid Chromatography Tandem Mass Spectrometry, Matthew Halquist

Theses and Dissertations

Immunoassays have traditionally been employed for the determination of plasma concentration-time profiles for pharmacokinetic studies of therapeutic proteins and peptides. These ligand binding assays have high sensitivity but require significant time for antibody generation (1 to 2 years) for assay development. Despite high sensitivity, these assays suffer from cross-reactivity that can lead to inaccurate results. As an alternative to immunoassays, this dissertation was focused on the development and validation of assays that can be used for quantitative analysis of peptides or proteins in plasma using liquid chromatography tandem mass spectrometry (LC-MS/MS). Two approaches were considered for measurement of proteins and …

Pharmacokinetic/Pharmacodynamic (Pk/Pd) Modeling Of Anti-Neoplastic Agents, Daniel Lexcen, Ahmed H. Salem, Walid F. Elkhatib, Virginia Haynes, Ayman Noreddin

Pharmacy Faculty Books and Book Chapters

"Development of tumor resistance to chemotherapeutics is related to inherent tumor variations regarding sensitivity to chemotherapeutics and to sub-optimal dosing regimens, including variation in patient pharmacokinetics that result in suboptimal exposure of tumor cells to anti-neoplastic drugs [1, 2]. The rate and extent of drug efficacy depends on the extent of drug exposure at the tumor site and the time above the effective concentration [3]. In vitro models that incorporate these pharmacokinetic and pharmacodynamic (PK/PD) principles to optimize therapeutic response may be considered the method of choice for optimizing dosing schedules before translating data from static assays to animals and …

Application Of Pharmacokinetics/Pharmacodynamics (Pk/Pd) In Designing Effective Antibiotic Treatment Regimens, Ghada F. Ahmed, Ayman Noreddin

Pharmacy Faculty Books and Book Chapters

"Designing antibiotic dosing regimens is often not optimal and the dose-response relationship for most antibiotics is not well-known1. Both Pharmacokinetics (PK) and Pharmacodynamics (PD) are characteristics of antimicrobial agents that should be considered in the development of effective antibiotic therapy. By linking the concentration time profile at the site of action to the drug effect (PK/PD), the effect of varying dosage regimens against pathogens could be simulated enabling the identification of effective dosage strategies. It is known that inadequate antibiotic dosing could not only lead to a therapeutic failure, but also to the development of bacterial resistance. Importantly, the evolution …

Surgical Delay For Hip Fracture Clients And The Use Of Clopidogrel: An Integrative Review, Phoebe Genevieve Waller

Senior Honors Theses

Abstract

Hip fractures in elderly patients have very high postoperative mortality rates and the number of hip fractures in the United States is expected to increase exponentially before 2030. Early surgery is essential to improve outcomes, but patients on clopidogrel (Plavix) have a high risk for increased bleeding if surgery is performed within the usual 72 hour window. This paper presents literature and research addressing the dangers of delaying surgery versus undergoing surgery before the effects of the clopidogrel are gone. Based on articles published after 2006, most researchers advocated earlier surgical intervention than previously recommended and emphasized an individualized …

Tuftsin Promotes An Anti-Inflammatory Switch And Attenuates Symptoms In Experimental Autoimmune Encephalomyelitis, Wu Muzhou, Julien Nissen, Emily Chen, Stella Tsirka

Department of Pharmacology Faculty Publications

Multiple sclerosis (MS) is a demyelinating autoimmune disease mediated by infiltration of T cells into the central nervous system after compromise of the blood-brain barrier. We have previously shown that administration of tuftsin, a macrophage/microglial activator, dramatically improves the clinical course of experimental autoimmune encephalomyelitis (EAE), a well-established animal model for MS. Tuftsin administration correlates with upregulation of the immunosuppressive Helper-2 Tcell (Th2) cytokine transcription factor GATA-3. We now show that tuftsin-mediated microglial activation results in shifting microglia to an anti-inflammatory phenotype. Moreover, the T cell phenotype is shifted towards immunoprotection after exposure to tuftsin-treated activated microglia; specifically, downregulation of …

Molecular Staging Individualizing Cancer Management, Alex Mejia, Stephanie Schulz, Terry Hyslop, David S. Weinberg, Scott A. Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Although the most important prognostic and predictive marker in colorectal cancer is tumor cells in lymph nodes, ∼30% of patients who are node-negative die from occult metastases. Molecular staging employing specific markers and sensitive detection technologies has emerged as a powerful platform to assess prognosis in node-negative colon cancer. Integrating molecular staging into algorithms that individualize patient management will require validation and the definition of relationships between occult tumor cells, prognosis, and responses to chemotherapy.

Recession Proof Pills: An Examination Of The Relationship Between Recession Economics And Pharmaceutical Expenditures, Kevin Gray

Annual Undergraduate Conference on Health and Society

The first decade of the 21st century proved to be a time of turbulence and volatility in the worldwide economy. Oddly enough, even as Americans’ disposable income decreased, spending on health care steadily increased. Americans spent $249.9 billion on prescription drugs in 2009, contrasted against $120.9 billion in 2000—a 105% increase.1 We may question the overall ramifications of such increases in pharmaceutical sales and the correlation to other economic factors. That is, how was the pharmaceutical sector able to boast gains when the housing market collapsed? One answer is that people place a priority on their health, even with limited …

A Cellular Automata Model Of Enantiomer Interactions With Beta-Cyclodextrin, Desoi Darren

Theses and Dissertations

The binding mechanisms of molecules to cyclodextrins continues to be studied to better explain the interactions occurring. The majority of published models focus on one-to-one molecular binding thermodynamics to explain experimental results. They rely on physical concepts of energies and forces to guide the actions of molecules expressed mathematically in terms of differential and non-linear equations. These models are limited in scope due to their complexity and are not easily expanded to study many diverse analytes. Conversely, cellular automata uses simple mathematical idealizations of systems governed by deterministic and probabilistic rules that are easily adaptable to many types of molecular …

Reactive Oxygen Species And Mitochondrial Sensitivity To Oxidative Stress Determine Induction Of Cancer Cell Death By P21, Ionica Masgras, Samantha Carrera, Petra J. De Verdier, Paul Brennan, Aneela Majid, Wan Makhtar, Eugene Tulchinsky, George D. Jones, Igor Roninson, Salvador Macip

Faculty Publications

p21(Waf1/Cip1/Sdi1) is a cyclin-dependent kinase inhibitor that mediates cell cycle arrest. Prolonged p21 up-regulation induces a senescent phenotype in normal and cancer cells, accompanied by an increase in intracellular reactive oxygen species (ROS). However, it has been shown recently that p21 expression can also lead to cell death in certain models. The mechanisms involved in this process are not fully understood. Here, we describe an induction of apoptosis by p21 in sarcoma cell lines that is p53-independent and can be ameliorated with antioxidants. Similar levels of p21 and ROS caused senescence in the absence of significant death in other cancer …
