Helper T effector cytokines implicated in asthma modulate the contractility of human airway smooth muscle (HASM) cells. We have reported recently that a profibrotic cytokine, transforming growth factor (TGF)-β1, induces HASM cell shortening and airway hyperresponsiveness. Here, we assessed whether TGF-β1 affects the ability of HASM cells to relax in response to β2-agonists, a mainstay treatment for airway hyperresponsiveness in asthma. Overnight TGF-β1 treatment significantly impaired isoproterenol (ISO)-induced relaxation of carbachol-stimulated, isolated HASM cells. This single-cell mechanical hyporesponsiveness to ISO was corroborated by sustained increases in myosin light chain phosphorylation. In TGF-β1–treated HASM cells, ISO ...

Graduate Theses, Dissertations, and Problem Reports

Detection of SCs in body fluids continue to be a challenge because of limited metabolism data, lack of standards and reference mass spectrometry data. In vivo and in vitro experiments help elucidate metabolite markers for novel psychoactive substances and can prompt synthesis of standards to verify proposed metabolites. In this study, metabolism of three SCs N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamine (PX-1), N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluropentyl)-1H-indazole-3-carboxamide (PX-2), and N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(cyclohexylmethyl)-1H-indazole-3-carboxamide (PX-3) were investigated using human liver microsomes. Previous studies showed PX-3 as the most potent CB1 and CB2 receptor agonist.

Half-life and clearance data were acquired using ...

Design, Synthesis, And Evaluation Of C5 Substituted Carbapenem Antibiotics To Counter Resistant Pathogens, Noora Mohammed S.A Al-Kharji

Chemistry Theses and Dissertations

The 21st century has seen a dramatic acceleration in the evolution of bacterial resistance. Many classes of commercial antibiotics, including most current commercial β-lactams, were structurally optimized to counter 20th century pathogens. The carbapenems represent the most potent and broadest spectrum of the β-lactams, representing crucial last line agents to treat lifethreatening infections. While the 21st century has seen the appearance of carbapenem-resistant strains, the basic substitution pattern of commercial carbapenem antibiotics has remained constant, other than minor modifications at the C2 position. This research will investigate whether substitution at an atypical carbapenem position, the C5 position, can improve the ...

Improving The Palatability Of Colonoscopy Preparations, Phuong Anh Hoang Nguyen, Darnell Leon Cuylear, Heather Elizabeth Canavan

Shared Knowledge Conference

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. The most reliable screening method of CRC is a colonoscopy which requires a 4-Liter polymer with electrolytes preparation. Two in five patients are non-compliant to their colonoscopy schedules, with many patients who abstain reporting refusal due to significant discomfort associated with this preparation. Furthermore, there are distinct gender differences in the tolerance of colonoscopy preparations in male and female populations. We hypothesize the differences in clinic are a result of toxic effects of the drug associated with poor mixing by individual patients. PEG, the drug ...

Posters-at-the-Capitol

Cisplatin is a chemotherapy compound effective against a variety of cancers. However, it can act as an ototoxin and cause hearing loss by promoting reactive oxygen species (ROS) production in auditory tissues. The antioxidant amino acid, L-serine has been hypothesized to lower levels of cisplatin-mediated ROS. In this project, we investigated whether L-serine can reduce cisplatin-mediated ROS production in auditory tissue and potentially act as an otoprotectant during cisplatin chemotherapy. We used a zebrafish utricular tissue culture system and fluorescent ROS indicator dye to spectrophotometrically measure if L-serine could decrease reactive oxygen species levels in cisplatin-treated tissues. We found that ...

A PEMFC is an electrochemical transducer that converts chemical energy into electrical energy. A Redox reaction takes place at its electrodes whereas the volatile biomolecules (e.g. ethanol) are oxidized at the anode and ambient oxygen is reduced at the cathode. The compounds which were the focus of this investigation were ethanol (C2H5OH) and isoflurane (C3H2ClF5O), but theoretically, the ...


Mycobacterium Tuberculosis Inhibitors: Action And Resistance, Pamela K. Garcia-Moreno 2018 Florida International University

Mycobacterium Tuberculosis Inhibitors: Action And Resistance, Pamela K. Garcia-Moreno

FIU Electronic Theses and Dissertations

Tuberculosis, an infectious disease caused by Mycobacterium tuberculosis, has been a global health problem for years. The emergence of drug resistance in this organism generates the necessity of exploring novel targets and developing new drugs. Topoisomerases are enzymes found in all kingdoms of life responsible for overcoming the topological barriers encountered during essential cellular processes. The genomes of mycobacteria encode only one type IA topoisomerase (MtopI), which has been validated as a novel TB drug target. The goal of this study is to obtain new information on the mechanism and resistance of endogenous and synthetic inhibitors of MtopI.

IMPROVING THE MANAGEMENT OF NATIONWIDE DRUG AND IV SHORTAGE

In September of 2017, Hurricane Maria struck the island of Puerto Rico where over 50 pharmaceutical factories had previously operated. The impact of this was felt not only in the drastic reduction of products that are produced on the island, but it also exacerbated the supply chain issues for key drugs nationwide.

The pharmacy department and supply chain in an academic tertiary care medical center did not have a consistent and reliable process for communication, planning and real-time updates. This resulted in a tremendous amount of wasted staff time at their ...

Microbial biofilms are organized communities of cells that are associated with a wide spectrum of resistant and chronic infections that lead to the treatment failure. Accordingly, there is an urgent demand to create novel effective therapeutic drugs that can inhibit biofilm formation with new mechanisms of action to surmount the current escalating resistance. In this study, in silico hybrid model was utilized to develop three novel short linear peptides (4, 5, and 6) with potential biofilm inhibiting activities (scores > 1.0). The peptides were composed of cationic and hydrophobic residues. They were synthesized using solid-phase strategy. Synthesized peptides were purified ...


The Legalization Of Medical/Recreational Marijuana: Implications For School Health Drug Education Programs, Joseph Donnelly, Michael Young 2018 Montclair State University

The Legalization Of Medical/Recreational Marijuana: Implications For School Health Drug Education Programs, Joseph Donnelly, Michael Young

Department of Public Health Scholarship and Creative Works

BACKGROUND

More than half of US states have legalized medical marijuana. Several states have also legalized it for recreational use. In spite of states' actions, marijuana remains illegal under federal law. It remains to be seen, however, if the Trump administration will enforce federal law in states that have legalized marijuana. For now, it appears the move toward state legalization of marijuana will increase. Because of its legal status, research concerning the medical benefits of marijuana has been limited.

METHODS

We reviewed the literature pertaining to medical use and legalization of marijuana.

RESULTS

Available research shows that marijuana can benefit ...


Polyrotaxane Variants And Their Effects On The Cholesterol Efflux In Patients Suffering From Niemann Pick Type C, Sydney Smith, Zach Struzik, David Thompson 2018 Purdue University

Polyrotaxane Variants And Their Effects On The Cholesterol Efflux In Patients Suffering From Niemann Pick Type C, Sydney Smith, Zach Struzik, David Thompson

The Summer Undergraduate Research Fellowship (SURF) Symposium

Niemann Pick type C disease (NPC) is a rare lysosomal storage disorder characterized by a progressive accumulation of cholesterol in the late endosomal/lysosomes compartment leading to cellular dysfunction and organ failure. Symptoms include ataxia, dysarthria, cognitive dysfunction, and seizures. Although average life expectancy is below 20, there are no FDA approved treatment available making it a serious unmet medical need. Clinical trials with 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) has shown promise in cholesterol normalization within NPC cells. However, HP-beta-CD treatment has been shown to cause ototoxicity in NPC patients at high dosages. Supramolecular complexes known as polyrotaxanes have been synthesized in hopes ...


Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra 2018 Purdue University

Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra

The Summer Undergraduate Research Fellowship (SURF) Symposium

Microglia are the brain’s resident immune cells that are responsible for maintaining homeostasis in healthy conditions. During injury or infection, resting microglia get activated and produce pro-inflammatory cytokines such as IL-1b, IL-1a, IL-6, etc. along with reactive oxygen species like nitric oxide (NO) to combat neuroinflammatory diseases such as Alzheimer’s disease (AD). Inflammation is characterized by the activation of resident-immune cells in the brain called microglia that respond to the eat-me signals released by the toxic amyloid beta peptides as well as the dying neurons in the microenvironment. Recent studies have shown that activated microglia induce neuronal death ...

A V-To-F Substitution In Sk2 Channels Causes Ca2+ Hypersensitivity And Improves Locomotion In A C. Elegans Als Model, Young-Woo Nam, Sabia N. Baskoylu, Dimitris Gazgalis, Razan Orfali, Meng Cui, Anne C. Hart, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels mediate medium afterhyperpolarization in the neurons and play a key role in the regulation of neuronal excitability. SK channels are potential drug targets for ataxia and Amyotrophic Lateral Sclerosis (ALS). SK channels are activated exclusively by the Ca2+-bound calmodulin. Previously, we identified an intrinsically disordered fragment that is essential for the mechanical coupling between Ca2+/calmodulin binding and channel opening. Here, we report that substitution of a valine to phenylalanine (V407F) in the intrinsically disordered fragment caused a ~6 fold increase in the Ca2+ sensitivity of SK2-a channels. This substitution resulted in a ...


Effects Of G Protein Signalling Modulator 3 On Cellular Signalling, Aneta A. Surmanski 2018 The University of Western Ontario

Effects Of G Protein Signalling Modulator 3 On Cellular Signalling, Aneta A. Surmanski

Electronic Thesis and Dissertation Repository

G protein coupled receptors (GPCRs) promote G protein heterotrimer (Gα·GDP/Gbg) activation.GPCRsignalling is limited via G protein GTPase activity and b-arrestin-receptor interactions. G Protein Signalling Modulators (GPSMs) are proteins that may influence receptor signalling through G protein activity. GPSM3 modulates their activity by binding to Gai-GDP, limiting nucleotide exchange and preventing its re-association to Gbg. The impact of GPSM3 on signalling is unknown.We hypothesize that GPSM3 will decrease Gai-dependent signalling while promoting Gbg-dependent signalling in Gi-coupled GPCRs.

GPSM3 significantly inhibited b-arrestin recruitment to α2A-adrenergic and m-opioid receptors via ...
