A Comparative Study Of Embedded And Anesthetized Zebrafish In Vivo On Myocardiac Calcium Oscillation And Heart Muscle Contraction, Brian S. Muntean, Christine M. Horvat, James H. Behler, Wissam A. Aboualaiwi, Andromeda M. Nauli, Frederick E. Williams, Surya M. Nauli

Pharmacy Faculty Articles and Research

The zebrafish (Danio rerio) has been used as a model for studying vertebrate development in the cardiovascular system. In order to monitor heart contraction and cytosolic calcium oscillations, fish were either embedded in methylcellulose or anesthetized with tricaine. Using high-resolution differential interference contrast and calcium imaging microscopy, we here show that dopamine and verapamil alter calcium signaling and muscle contraction in anesthetized zebrafish, but not in embedded zebrafish. In anesthetized fish, dopamine increases the amplitude of cytosolic calcium oscillation with a subsequent increase in heart contraction, whereas verapamil decreases the frequency of calcium oscillation and heart rate. Interestingly, verapamil also …

Development And Evaluation Of Paclitaxel-Loaded Liposomal Formulations For Targeted Drug Delivery To Breast Cancer, Vinayagam Kannan

Theses and Dissertations (ETD)

The objective of this work was to develop and evaluate paclitaxel-loaded liposomal formulations for targeted drug delivery to breast cancer. The liposomal formulation was optimized to maximize drug loading and physical stability. Cholesterol and saturated lipid content showed a negative influence on paclitaxel loading. Short-term stability studies showed that optimum drug-lipid ratio is necessary for adequate physical stability. Biodistribution studies in mouse xenografts bearing MDA-MB-231 breast cancer using near infrared fluorescence imaging showed that the accumulation of tumor vasculature targeted long-circulating liposomes (LCL) in the tumor was significantly less than non-targeted LCL at 48 h. The accumulation of these liposomes …

Exhausted Or Unlicensed: Can Field-Of-Use Restrictions In Biotech License Agreements Still Prevent Off-Label Use Promotion After Quanta Computer?, Kristal M. Wicks

The University of New Hampshire Law Review

[Excerpt] “In the biotechnology (biotech) industry, companies must be increasingly aware of their intellectual property and how their licensing strategies can impact their rights. When licensing patented technology, it is common practice for biotech companies to include restricted field-of-use provisions in their license agreements. Such provisions permit a licensee to only use licensed technology in a defined field and restrict use or development in another field. This licensing strategy plays an important role within the biotech industry because it allows companies to more effectively control their intellectual property and to more efficiently research and develop pharmaceutical products.

Therapeutic Gene Delivery To Human Pancreatic Islets For Treatment Of Diabetes And The Effect Of Tfo On Liver Fibrosis Induced By Bile Duct Ligation, Ravikiran Panakanti

Theses and Dissertations (ETD)

Ex vivo gene transfer can improve the outcome of islet transplantation for treating Type I diabetes. Earlier we have shown co‑expression of human vascular endothelial growth factor (hVEGF) and human interleukin‑1 receptor antagonist (hI‑1Ra) after transfection of plasmid DNA encoding these two genes. Due to poor transfection efficiency of plasmid DNA and the better known islet transduction efficiency of adenoviral (Adv) vectors, in this study, we constructed Adv‑hVEGF‑hIL‑1Ra by cloning hVEGF and hIL‑1Ra coding sequences and polyA signal under separate cytomegalovirus (CMV) promoters in Adenoquick plasmid (Ad 13.1). There was dose and time dependent expression of these genes after transduction …

At₁ Angiotensin Ii Receptor And Novel Non-At₁, Non-At₂ Angiotensin Ii/Iii Binding Site In Brainstem Cardiovascular Regulatory Centers Of The Spontaneously Hypertensive Rat, Erick A. Bourassa, Xiefan Fang, Xia Li, Alan F. Sved, Robert C. Speth

HPD Articles

Spontaneously hypertensive rats (SHR) have an activated brain angiotensin system that contributes to the elevation of blood pressure in this animal model. Physiological and pharmacological studies suggest that hyperactivation of brain AT₁ angiotensin receptors is a major pathophysiological factor. Consistent with these observations, radioligand binding studies indicate widespread up-regulation of brain angiotensin receptors in SHR. One key brainstem site in which AT₁ receptor stimulation appears to contribute to the elevated blood pressure in SHR is the rostral ventrolateral medulla (RVLM). However, no quantitative comparison of AT₁ receptor binding in the RVLM has been made in SHR versus normotensive rats. A …

Dna Synapsis Through Transient Tetramerization Triggers Cleavage By Ecl18ki Restriction Enzyme., Mindaugas Zaremba, Amelia Owsicka, Gintautas Tamulaitis, Giedrius Sasnauskas, Luda S. Shlyakhtenko, Alexander Y. Lushnikov, Yuri L. Lyubchenko, Niels Laurens, Bram Van Den Broek, Gijs J.L. Wuite, Virginijus Siksnys

Journal Articles: Pharmaceutical Sciences

To cut DNA at their target sites, restriction enzymes assemble into different oligomeric structures. The Ecl18kI endonuclease in the crystal is arranged as a tetramer made of two dimers each bound to a DNA copy. However, free in solution Ecl18kI is a dimer. To find out whether the Ecl18kI dimer or tetramer represents the functionally important assembly, we generated mutants aimed at disrupting the putative dimer-dimer interface and analysed the functional properties of Ecl18kI and mutant variants. We show by atomic force microscopy that on two-site DNA, Ecl18kI loops out an intervening DNA fragment and forms a tetramer. Using the …

An In Vitro Model For Pelger-Huët Anomaly, Ada L. Olins, Aurélie Ernst, Monika Zwerger, Harald Hermann, Donald E. Olins

Pharmaceutical Sciences Faculty Publications

The principal human blood granulocyte (neutrophil) possesses a lobulated and deformable nucleus, important to facilitate rapid egress from blood vessels as these cells migrate to sites of bacterial or fungal infection. This unusual nuclear shape is a product of elevated levels of an integral membrane protein of the nuclear envelope lamin B receptor (LBR) and of decreased amounts of lamin A/C. In humans, a genetic deficiency of LBR produces Pelger-Huët anomaly, resulting in blood neutrophils that exhibit hypolobulated nuclei with redistributed heterochromatin. Structural changes in nuclear architecture occur during granulopoiesis within bone marrow. The exact mechanisms of this nuclear shape …

Psychiatric Taxonomy, Psychopharmacology And Big Pharma, Lisa Cosgrove

Counseling, School Psychology & Sport Faculty Publication Series

Clinicians practicing today need to be aware of the ways in which the current industry-dominated climate may undermine the integrity of the scientific process and, thus, may compromise patient care. In the mental health field, corporate sponsorship bias can affect psychiatric taxonomy and clinical Practice Guidelines (CPG). Financial conflicts of interest (FCOI) can occur when there are financial associations between researchers, authors, or panel members developing psychiatric diagnostic and treatment guidelines, and the pharmaceutical industry, or when randomized clinical trials (RCTs) are industry funded. Therefore, clinicians need to be especially vigilant about the informed consent process when patients are prescribed …

Preliminary Studies Into Dna Binding Capabilities Of Ruthenium Nitro Nitrosyl As Anti-Tumor Pro-Drugs, Natasha Hansson

Seton Hall University Dissertations and Theses (ETDs)

The complex [Ru(bpy)z(NO)(N02)](PF6)2 was investigated as a potential anti­ tumor drug option. The nitrosyl group was displaced by reaction with azide ion in acetone to yield the solvento complex in situ. The products isolated from addition of a solution or slurry of guanine, adenine, cytosine or thiamine to the resulting [Ru(bpy)(N02)(acetone)t were investigated by electronic absorption spectroscopy, infra­ 1 red spectroscopy, H NMR spectroscopy and cyclic voltammetry. The results of the studies showed that guanine, adenine and thiamine form adducts with Ru(bpy)z(N02)(acetone)t. However, each base forms a unique complex as shown by electronic spectroscopy. Guanine is the strongest field ligand, …

Failure To Ubiquitinate C-Met Leads To Hyperactivation Of Mtor Signaling In A Mouse Model Of Autosomal Dominant Polycystic Kidney Disease, Shan Qin, Mary Taglienti, Surya M. Nauli, Leah Contrino, Ayumi Takakura, Jing Zhou, Jordan A. Kreidberg

Pharmacy Faculty Articles and Research

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disorder that is caused by mutations at two loci, polycystin 1 (PKD1) and polycystin 2 (PKD2). It is characterized by the formation of multiple cysts in the kidneys that can lead to chronic renal failure. Previous studies have suggested a role for hyperactivation of mammalian target of rapamycin (mTOR) in cystogenesis, but the etiology of mTOR hyperactivation has not been fully elucidated. In this report we have shown that mTOR is hyperactivated. in Pkd1-null mouse cells due to failure of the HGF receptor c-Met to be properly ubiquitinated and subsequently …

These advantages include reduced dosing frequency, better therapeutic control, fewer side effects, and, consequently, these dosage forms are well accepted by patients. Advances in polymer material science, particle engineering design, manufacture, and nanotechnology have led the way to the introduction of several marketed controlled release products and several more are in pre-clinical and clinical development.

Identification Of Thioaptamer Ligand Against E-Selectin: Potential Application For Inflamed Vasculature Targeting., Aman P Mann, Anoma Somasunderam, René Nieves-Alicea, Xin Li, Austin Hu, Anil K Sood, Mauro Ferrari, David G Gorenstein, Takemi Tanaka

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Active targeting of a drug carrier to a specific target site is crucial to provide a safe and efficient delivery of therapeutics and imaging contrast agents. E-selectin expression is induced on the endothelial cell surface of vessels in response to inflammatory stimuli but is absent in the normal vessels. Thus, E-selectin is an attractive molecular target, and high affinity ligands for E-selectin could be powerful tools for the delivery of therapeutics and/or imaging agents to inflamed vessels. In this study, we identified a thiophosphate modified aptamer (thioaptamer, TA) against E-selectin (ESTA-1) by employing a two-step selection strategy: a recombinant protein-based …
