Vestibular Stimulation Enhances Hippocampal Long-Term Potentiation Via Activation Of Cholinergic Septohippocampal Cells, Leung L. Stan

Physiology and Pharmacology Publications

Vestibular stimulation induced acetylcholine release in the hippocampus, and acetylcholine is known to facilitate long-term potentiation (LTP) in the hippocampus. Thus, we hypothesize that vestibular stimulation enhances LTP in CA1 in freely behaving rats, and this enhancement depends on the activation of septohippocampal cholinergic neurons. Field excitatory postsynaptic potentials were recorded in CA1 area of behaving rats following stimulation of the basal dendritic afferents. LTP was induced by a single stimulation train (100 pulses at 200 Hz) during passive whole-body rotation or during awakeimmobility. LTP induced during rotation was significantly larger than that induced during immobility. Pretreatment with cholinergic antagonist …

Clinical Evaluation Of Novel Methods For Extending Microneedle Pore Lifetime, Nicole K. Brogden

Theses and Dissertations--Pharmacy

Microneedles are a minimally invasive method for delivering drugs through the impermeable skin layers, and have been used to deliver a variety of compounds including macromolecules, vaccines, and naltrexone. Microneedles can be applied to the skin once, creating micropores that allow for drug delivery into the underlying circulation from a drug formulation. The utility of this technique, however, is blunted by rapid micropore closure. This research project sought to: 1) characterize micropore lifetime and re-sealing kinetics, and 2) prolong micropore lifetime via inhibition of the skin’s barrier restoration processes. Impedance spectroscopy was used as a surrogate technique in animals and …

N-Myristoylglutamic Acid Derivative Of 3′-Fluoro-3′- Deoxythymidine As An Organogel, Bhupender S. Chhikara, Rakesh Tiwari, Keykavous Parang

Pharmacy Faculty Articles and Research

Designing microbicidal gels of anti-HIV drugs for local application to prevent HIV infection is a subject of major interest. 3′-Fluoro-3′-deoxythymidine (FLT), a nucleoside reverse transcriptase inhibitor (NRTI), was conjugated with a N-myristoylglutamate scaffold. The conjugate showed gelation at 1% (w/w) in different organic solvents, such as toluene, dichloromethane, and chloroform. The gels were opaque and stable at room temperature. The results indicate that myristoyl glutamate derivative of FLT can form an organogel. The gel could have potential application as a topical anti-HIV microbicidal agent.

Pharmacy Faculty Articles and Research

Developing vehicles for the delivery of therapeutic molecules, like siRNA, is an area of active research. Nanoparticles composed of bovine serum albumin, stabilized via the adsorption of poly-L-lysine (PLL), have been shown to be potentially inert drug-delivery vehicles. With the primary goal of reducing nonspecific protein adsorption, the effect of using comb-type structures of poly(ethylene glycol) (1 kDa, PEG) units conjugated to PLL (4.2 and 24 kDa) on BSA-NP properties, apparent siRNA release rate, cell viability, and cell uptake were evaluated. PEGylated PLL coatings resulted in NPs with ζ-potentials close to neutral. Incubation with platelet-poor plasma showed the composition of …

The Pharmacokinetics And Toxicology Of Aluminum In The Brain, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

The chemical forms (species) of aluminum in blood plasma and brain extracellular fluid are considered, as they are the candidates for brain aluminum uptake and efflux. The blood-brain barrier is the primary site of brain aluminum uptake. The mechanism of brain uptake of aluminum transferrin, long thought to be mediated by transferrin-receptor mediated endocytosis, requires further investigation. Brain Al citrate uptake has been attributed to the sodium-independent Lglutamate/ L-cystine exchanger system, system Xc-. Reports have suggested aluminum can compromise blood-brain barrier integrity, however the studies were conducted with aluminum concentrations greatly exceeding those seen in human blood plasma. Aluminum appeared …

The Identification And Reduction Of Energy Streams Within The Pharmaceutical Sector Using Software Algorithms, Raymond Corbett

Theses

Pharmaceutical companies are under increasing financial pressure to optimise production costs, due to a growing number of products coming off patent, research and development costs increasing exponentially and the difficulty of bringing genuinely innovative products to market. Generic drug manufacturers are not exempt from these pressures; costs must be driven down by all drug manufacturers due to the increasingly competitive healthcare market.

The operating costs of a modern Pharmaceutical Plant run to several Million Euros per annum. Complex process’s involving the consumption of large amounts of energy, and hence costs, are a necessity. Any increase in the efficiency of a …

Melatonin Membrane Receptors In Peripheral Tissues: Distribution And Functions, Radomir M. Slominski, Russel J. Reiter, Natalia Schlabritz-Loutsevich, Rennolds S. Ostrom, Andrzej T. Slominski

Pharmacy Faculty Articles and Research

Many of melatonin’s actions are mediated through interaction with the G-protein coupled membrane bound melatonin receptors type 1 and type 2 (MT1 and MT2, respectively) or, indirectly with nuclear orphan receptors from the RORα/RZR family. Melatonin also binds to the quinone reductase II enzyme, previously defined the MT3 receptor. Melatonin receptors are widely distributed in the body; herein we summarize their expression and actions in non-neural tissues. Several controversies still exist regarding, for example, whether melatonin binds the RORα/RZR family. Studies of the peripheral distribution of melatonin receptors are important since they are attractive targets for immunomodulation, regulation of endocrine, …

Cytomegalovirus Cc Chemokine Promotes Immune Cell Migration, Jennifer Totonchy, Michael Denton, Craig N. Kreklywich, Takeshi Andoh, Jessica M. Osborn, Daniel Chen, Ilhem Messaoudi, Susan L. Orloff, Daniel N. Streblow

Pharmacy Faculty Articles and Research

Cytomegaloviruses manipulate the host chemokine/receptor axis by altering cellular chemokine expression and by encoding multiple chemokines and chemokine receptors. Similar to human cytomegalovirus (HCMV), rat cytomegalovirus (RCMV) encodes multiple CC chemokine-analogous proteins, including r129 (HCMV UL128 homologue) and r131 (HCMV UL130 and MCMV m129/130 homologues). Although these proteins play a role in CMV entry, their function as chemotactic cytokines remains unknown. In the current study, we examined the role of the RCMV chemokine r129 in promoting cellular migration and in accelerating transplant vascular sclerosis (TVS) in our rat heart transplant model. We determined that r129 protein is released into culture …

Combination Effects Of Docetaxel And Doxorubicin In Hormone-Refractory Prostate Cancer Cells, Eleftheria Tsakalozou, Allison M. Eckman, Younsoo Bae

Pharmaceutical Sciences Faculty Publications

Combination effects of docetaxel (DOC) and doxorubicin (DOX) were investigated in prostate cancer cells (PC3 and DU145). Combination indices (CIs) were determined using the unified theory in various concentrations and mixing ratios (synergy: CI < 0.9, additivity: 0.9 < CI < 1.1, and antagonism: CI > 1.1). DOC showed a biphasic cytotoxicity pattern with the half maximal inhibitory concentration (IC50) at the picomolar range for PC3 (0.598 nM) and DU145 (0.469 nM), following 72 h drug exposure. The IC50s of DOX were 908 nM and 343 nM for PC3 and DU145, respectively. Strong synergy was seen when PC3 was treated with DOC at concentrations lower than its IC50 values (0.125~0.5 nM) plus …

Ceria-Engineered Nanomaterial Distribution In, And Clearance From, Blood: Size Matters, Mo Dan, Peng Wu, Eric A. Grulke, Uschi M. Graham, Jason M. Unrine, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

AIMS: Characterize different sized ceria-engineered nanomaterial (ENM) distribution in, and clearance from, blood (compared to the cerium ion) following intravenous infusion.

MATERIALS & METHODS: Cerium (Ce) was quantified in whole blood, serum and clot (the formed elements) up to 720 h.

RESULTS: Traditional pharmacokinetic modeling showed best fit for 5 nm ceria ENM and the cerium ion. Ceria ENMs larger than 5 nm were rapidly cleared from blood. After initially declining, whole blood 15 and 30 nm ceria increased (results that have not been well-described by traditional pharmacokinetic modeling). The cerium ion and 5 and 55 nm ceria did not …
