Seton Hall University Dissertations and Theses (ETDs)
Over the past two decades, advances in RNA structural biology have improved our understanding of the structures and folding properties of naturally occurring RNAs. RNA sequences and structures participate in many specific biological functions, such as those performed by messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), micro RNA (miRNA), short-interfering RNA (siRNA), small nuclear RNA (snRNA) and many others. The noncoding RNAs, such as siRNA, do not express proteins but have been utilized in a wide range of applications, including RNA interference (RNAi) and the regulation of mRNA expression. These important biological functions have been implemented in gene ...

Title: Incidence of hypomagnesemia on proton pump inhibitors at the Huntington Veterans Affairs Medical Center – IHOP
Proton pump inhibitors (PPIs), both prescription and over-the-counter, are widely used for the treatment of acid-related disease states such as dyspepsia, gastroesophageal reflex disease, esophagitis, and peptic ulcers. These medications are generally considered safe in most patient populations; however, there are several adverse effects that may occur with long-term use. Hypomagnesemia is a newer complication arising in the literature following multiple case reports over the past several years, although the true incidence of hypomagnesemia associated with PPI use remains unclear at this ...

UMass Center for Clinical and Translational Science Research Retreat
Soil-transmitted helminths (STHs), most notably, hookworms, whipworms, and Ascaris, are nematodes that infect more than 1.5 billion of the poorest people and are amongst the leading causes of morbidity worldwide. Only two classes of de-worming drugs (anthelmintics) are available for treatment, and only one is commonly used in mass drug administrations. New anthelmintics are urgently needed to overcome emerging resistance and to produce higher cure rates. Crystal (Cry) proteins, in particular Cry5B, made by Bacillus thuringiensis (Bt) are promising new candidates. Cry5B has excellent anthelmintic properties against many free-living and parasitic nematodes, including in vivo efficacy against multiple STH ...

Theoretical And Experimental Analysis Of The Antioxidant And Anti-Amyloid Features Of Synthetic Resveratrol Mimics, William Horton, Anne Kokel, Fanni Török, Chris Tran, Marianna Török, Bela Török
UMass Center for Clinical and Translational Science Research Retreat
Diaryl hydrazones, possessing similar structure to the popular red wine antioxidant resveratrol, have been previously identified as multitarget compounds interfering with several processes associated with the pathogenesis of Alzheimer’s disease (AD). These compounds exhibited particularly strong inhibition of the amyloid beta (A) peptide self-assembly, including blocking the formation of fibrils and oligomers, species that are widely accepted to be neurotoxic. The molecules were also powerful free radical scavengers and thus have a potential to defend against oxidative stress.
In order to learn more about the mode of action of the compounds, theoretical and experimental studies have been carried out ...

Hit Identification For Pkcζ Inhibitors: Structure-Based Optimization, Virtual Screening, And Biological Evaluation, Xiaoxin Wu
Theses and Dissertations (ETD)
Protein kinase C ζ (PKCζ) is believed to be a promising target for the treatment of some diseases, including inflammatory diseases, obesity and diabetes. Hit identification of PKCζ inhibitors was conducted by structure-based modification, virtual screening and biological evaluation. Among all the compounds selected and synthesized, compound JW-1-60A showed moderate activity against PKCζ at 30 μM and 100 μM. The molecular modeling studies showed that the binding mode of JW-1-61A was very close to the binding mode of JP-3-149, a reported PKCζ inhibitor with very potent activity, which might partially explain the moderate activity of JW-1-61A. Based on the structure ...
Upregulation Of Antibiotic Activity Of A Streptomyces Sp. Via Co-Cultures With Challenge Pathogens, 2016 University of Connecticut - Storrs
Upregulation Of Antibiotic Activity Of A Streptomyces Sp. Via Co-Cultures With Challenge Pathogens, Anne A. Sung
Honors Scholar Theses
Marine natural product drug discovery has begun to play an important role in the treatment of diseases. Early drug discovery from natural products came primarily from plants, but after the discovery and development of penicillin, scientists started looking at natural products from microorganisms. Numerous natural products have been discovered from members of the order Actinomycetales, particularly in the genus Streptomyces, due to their metabolic diversity in the production of biologically active secondary metabolites. Ascidians, also known as tunicates, are marine invertebrates that contain many host-associated microbes. Adult tunicates are sessile, which makes them vulnerable to predators, and thus, they are ...
Urinary Alkalisation For Symptomatic Uncomplicated Urinary Tract Infection In Women (Review), Dermot B. O'Kane, Sameer Dave, Neel Gore, Farhaan Patel, Tammy Hoffmann, Jeanne L. Trill, Chris Del Mar
Christopher Del Mar
Uncomplicated urinary tract infection (UTI) is the most common bacterial infection in women, characterised by dysuria and urinary frequency. Urinary alkalisers are widely used in some countries for the symptomatic treatment of uncomplicated UTI, and they are recommended in some national formularies. However, there is a lack of empirical evidence to support their use for UTI and some healthcare guidelines advise against their use.
We aimed to look at the benefits and harms of the use of urinary alkalisers for the treatment of uncomplicated UTIs in adult women.
We searched the Cochrane Kidney and Transplant Specialised ...
Rapid Effects Of Aldosterone And Spironolactone In The Isolated Working Rat Heart, 2016 Marshall University
Rapid Effects Of Aldosterone And Spironolactone In The Isolated Working Rat Heart, John C. Barbato, Patrick J. Mulrow, Joseph I. Shapiro Md, Roberto Franco-Saenz
Joseph I Shapiro MD
Chronic administration of aldosterone promotes myocardial fibrosis in rats. The Randomized Aldactone Evaluation Study reported that the aldosterone antagonist spironolactone improved outcome in patients with congestive heart failure, suggesting a deleterious effect of aldosterone in the heart. Aldosterone has been shown to have rapid nongenomic effects in different tissues including the heart. However, the hemodynamic actions of aldosterone and spironolactone are not well characterized. In this study, we examined the hemodynamic effects of aldosterone and its receptor antagonist, spironolactone, in the isolated rat heart by use of the Langendorff-Neely technique. Perfusion with 10 nmol/L aldosterone increased contractility by 45 ...
Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, 2016 Northwestern Polytechnical University
Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, Peican Zhu, Hamidreza Montazeri Aliabadi, Hasan Uludag, Jie Han
Pharmacy Faculty Articles and Research
The investigation of vulnerable components in a signaling pathway can contribute to development of drug therapy addressing aberrations in that pathway. Here, an original signaling pathway is derived from the published literature on breast cancer models. New stochastic logical models are then developed to analyze the vulnerability of the components in multiple signalling sub-pathways involved in this signaling cascade. The computational results are consistent with the experimental results, where the selected proteins were silenced using specific siRNAs and the viability of the cells were analyzed 72 hours after silencing. The genes elF4E and NFkB are found to have nearly no ...

An Evaluation Of Antibiotic Resistance: Structure-Activity Relationship Studies Of Tetracyclic Indolines As A Novel Class Of Resistance-Modifying Agents For Mrsa & Analysis Of Recent Fda Regulations On Antibiotic Use In Livestock, 2016 University of Colorado, Boulder
An Evaluation Of Antibiotic Resistance: Structure-Activity Relationship Studies Of Tetracyclic Indolines As A Novel Class Of Resistance-Modifying Agents For Mrsa & Analysis Of Recent Fda Regulations On Antibiotic Use In Livestock, Lakota K. Cleaver
Undergraduate Honors Theses
While the rate at which resistance develops against antimicrobials rises, research and development for new antimicrobials declines. By placing selective pressure on bacteria we are inadvertently forcing bacteria into expressing and propagating genes conferring high levels of resistance. Continued misuse and overuse of antibiotics, in light of the evident problem developing, must be resolved. To find a resolve, a multidisciplinary and multifaceted approach must be taken which involves 1) research and development of novel antimicrobial agents and 2) governmental regulation.
Strides in new antimicrobial drug development largely revolve around making old antibiotics usable again. Resistance-Modifying Agents (RMAs) act to re-sensitize ...

Design And Structure-Activity Relationship Of Small Molecule C-Terminal Binding Protein (Ctbp) Inhibitors And Investigation Of The Scope Of Palladium Multi-Walled Carbon Nanotubes (Pd-Mwcnt) Catalyst In C–H Activation Reactions, Sudha Korwar
Theses and Dissertations
C-terminal binding proteins (CtBPs) are transcriptional co-repressors involved in developmental processes, and also implicated in a number of breast, ovarian, colon cancers, and resistance against cancer chemotherapy. CtBP is a validated novel potential anti-cancer target. In this project we sought to develop potent and selective small-molecule inhibitors of CtBP. Using a combination of classical medicinal chemistry and modern computational approaches, we designed a potent inhibitor HIPP (hydroxyimino-3-phenylpropanoic acid) that showed an IC50 of 0.24 μM against recombinant CtBP. Further elucidation of the structure-activity relationship (SAR) of HIPP led to the design of more potent inhibitors 3-Cl HIPP (CtBP ...
