Sirna Knock-Down Of Vav1 In Breast Cancer Cells: Effects On Pi3kinase And Akt, Tajai Sion-Milligan
Student Scholar Showcase
One in eight women in the United States will be diagnosed with breast cancer. Approximately 25-30% of these breast tumors will overexpress Human Epidermal Growth Factor Receptor 2 (HER2), associated with a worse prognosis and decreased survival rate. Stimulation of HER2 results in activation and production of many signaling molecules, ultimately resulting in increased cell division. Two of the downstream molecules activated are PI3Kinase and, further downstream, the molecule Akt. Typically, overproduction and/or overactivation of PI3Kinase can lead to oncogenesis. A molecule that may have a significant role in PI3Kinase formation is VAV1 ...
Antibiotic Residues In Milk From Three Popular Kenyan Milk Vending Machines, 2018 Eastern Kentucky University
Antibiotic Residues In Milk From Three Popular Kenyan Milk Vending Machines, Amos Kosgey, Anakalo Shitandi, Jason W. Marion
EKU Faculty and Staff Scholarship
Milk vending machines (MVMs) are growing in popularity in Kenya and worldwide. Milk vending machines dispense varying quantities of locally sourced, pasteurized milk. The Kenya Dairy Board has a regulatory framework, but surveillance is weak because of several factors. Milk vending machines’ milk is not routinely screened for antibiotics, thereby increasing potential for antibiotic misuse. To investigate, a total of 80 milk samples from four commercial providers (N = 25), street vendors (N = 21), and three MVMs (N = 34) were collected and screened in Eldoret, Kenya. Antibiotic residue surveillance occurred during December 2016 and January 2017 using Idexx SNAP tests for ...

Acute Hepatic Failure And Oral Amiodarone, Hani Alhamoud, Sivateja Mandava, Talal Alzahrani
GW Research Days 2016 - Present
Amiodarone is associated with serious complications such as lung toxicity, thyroid dysfunction, and QT-prolongation. Further, hepatic failure from the intravenous (IV) formulation of amiodarone is described in numerous case reports and case series. Although there are reports of elevated liver enzymes from the oral formulation of amiodarone, to our knowledge, none have definitively identified a case of acute hepatic failure from the oral formulation alone. In this case, we report an instance of acute hepatic failure after increasing the oral amiodarone dosage as well as rapid recovery following cessation of the medication.

Onyx Use In Extracranial Pathologies - A Retrospective Case Review, Faezeh Razjouyan, Rishi Sood, Alex Cho, Anthony Venbrux, Shawn Sarin
GW Research Days 2016 - Present
Onyx is an embolic agent currently FDA approved for neurointerventional procedures such as in the treatment of aneurysms and arteriovenous malformations. Despite its limited indications, the agent's off-label use in the treatment of extracranial pathologies continues to increase. To date, there has not been a single-center study demonstrating a large number of cases demonstrating safe and effective peripheral embolization with Onyx.
We performed a retrospective review of all cases that used Onyx between October 2010 and July 2016 at a single tertiary care academic university urban hospital. Institutional review board approval was appropriately obtained. Initial case selection ...

According to the CDC, opioid prescriptions in the United States have more than tripled from 1999-2014, which has correlated with the staggering increase in opioid-involved drug overdose deaths. This pattern of prescription is thought to be a major contributory factor to the increase in drug overdose in America, as four out of five new heroin users started by misusing prescription painkillers. Providers need the means to objectively monitor analgesic efficacy of treatment in patients with pain to mitigate unnecessary analgesic prescribing.
It is well established that mu opioid agonists like morphine cause miosis, an effect to which tolerance does not ...
Cannabis-Related Content In North American Post-Secondary Curricula: A Scoping Review, 2018 Thompson Rivers University
Cannabis-Related Content In North American Post-Secondary Curricula: A Scoping Review, Tianhao Xiao
Proceedings of the Annual Thompson Rivers University Undergraduate Research and Innovation Conference
On 11 August 2016, the Canadian government announced the new Access to Cannabis for Medical Purposes Regulations (ACMPR) outlining reasonable uses of cannabis for medical purposes. Educators teaching cannabis-related content face new challenges, as this legalization requires a shift away from a focus on substance abuse towards incorporating economic, social, and health promotion aspects. I report on what curricula incorporating the concept of cannabis are offered by post-secondary institutions as well as how and for what purpose this content is offered. To do this, I conducted a scoping review of published and grey literature to determine the extent of the ...
Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, 2018 University of Nebraska at Omaha
Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, Eunice Wintona
Student Research and Creative Activity Fair
Smoothened receptor (SMO) is a protein that in humans, is encoded by the SMO gene. A systemic mutation in its binding pocket helps predict the sensitivity of mutant proteins to different drugs. Known as a GPCR-like receptor, it is a component of the hedgehog signaling pathway; a pathway involved in body patterning and the regulation of adult stem cells. An uncontrolled or inappropriate activation of the Hedgehog pathway drives tumor progression in cancers and a number of birth defects. To achieve these goals, the molecular modeling software MOE was used to build small molecules and drug molecules like Vismodegib and ...

Corneal neovascularization (NV) is the major sight-threatening pathology caused by angiogenic stimuli. Current drugs that directly target pro-angiogenic factors to inhibit or reverse the disease require multiple rounds of administration and have limited efficacies. Here, we identify potential anti-angiogenic corneal microRNAs (miRNAs) and demonstrate a framework that employs discovered miRNAs as biotherapies deliverable by recombinant adeno-associated viruses (rAAVs). By querying differentially expressed miRNAs in neovascularized mouse corneas induced by alkali burn, we have revealed 39 miRNAs that are predicted to target more than 5,500 differentially expressed corneal mRNAs. Among these, we selected miR-204 and assessed its efficacy and therapeutic ...

Sandhoff disease, one of the GM2 gangliosidoses, is a lysosomal storage disorder characterized by the absence of beta-hexosaminidase A and B activity and the concomitant lysosomal accumulation of its substrate, GM2 ganglioside. It features catastrophic neurodegeneration and death in early childhood. How the lysosomal accumulation of ganglioside might affect the early development of the nervous system is not understood. Recently, cerebral organoids derived from induced pluripotent stem (iPS) cells have illuminated early developmental events altered by disease processes. To develop an early neurodevelopmental model of Sandhoff disease, we first generated iPS cells from the fibroblasts of an infantile Sandhoff disease ...

Statistics show approximately 15 million Americans suffer from NASH, a nonalcoholic fatty liver disease that is projected to become the most common reason for liver transplantation. There are no FDA approved therapies for NASH, so doctors are forced to treat patients with off-label medications while keeping an eye out for breakthroughs in medication development.
Two novel therapies, obeticholic acid and elafibranor, are currently in Phase III trials. If they receive FDA approval, interest will be high as they will be the first treatments specifically labeled for NASH. We detail a budget impact model for a sample state Medicaid plan in ...

The Biologics Price Competition And Innovation Act: Is A Generic Market For Biologics Attainable?, Kasey E. Koballa
William & Mary Business Law Review
The Biologics Price Competition and Innovation Act of 2009 (BPCIA) provides an abbreviated approval pathway for biological therapeutic products shown to be biosimilar to an FDA-approved biological reference product. The BPCIA purported to reduce the price of biologics while promoting innovation. In two recent cases, the Federal Circuit interpreted a key provision of the BPCIA requiring an applicant to provide the reference product sponsor with notice 180 days before marketing the product. The Federal Circuit’s interpretation extends the exclusivity period already provided for the reference product sponsor, deterring innovation and price reduction. Thus, the Supreme Court granted certiorari in ...

Small interfering RNA (siRNA)-based drugs require chemical modifications or formulation to promote stability, minimize innate immunity, and enable delivery to target tissues. Partially modified siRNAs (up to 70% of the nucleotides) provide significant stabilization in vitro and are commercially available; thus are commonly used to evaluate efficacy of bio-conjugates for in vivo delivery. In contrast, most clinically-advanced non-formulated compounds, using conjugation as a delivery strategy, are fully chemically modified (100% of nucleotides). Here, we compare partially and fully chemically modified siRNAs in conjugate mediated delivery. We show that fully modified siRNAs are retained at 100x greater levels in various ...

BACKGROUND: Chromobox protein homolog 7 (CBX7), a member of the polycomb group (PcG) family of proteins, is involved in the regulation of cell proliferation and cancer progression. PcG family members, such as BMI, Mel-18, and EZH2, are integral constituents of the polycomb repressive complexes (PRCs) and have been known to regulate cancer stem cell (CSC) phenotype. However, the role of other PRCs' constituents such as CBX7 in the regulation of CSC phenotype remains largely elusive. This study was to investigate the role of CBX7 in regulating stem cell-like properties of gastric cancer and the underlying mechanisms.
METHODS: Firstly, the role ...

Department of Biological & Biomedical Sciences
Simian virus 40 large T-antigen (SV40 LT-Ag) is a 708 amino acid nuclear phosphoprotein. Among many functions of LT-Ag is its ability to perform as an ATPase-helicase, catalyzing the unwinding of viral genome during replication. The LT-Ag has been employed in the studies of helicase structure and function, and has served as a model helicase for the screening of antiviral drugs that target viral helicase. In this study, using in vitro enzyme assays and in silico computer modeling, we screened a batch of 18 fluoroquinolones to assess their potential as antivirals by virtue of their inhibition of the LT-Ag helicase ...
Matrix Metalloproteinase-14 Is A Mechanically Regulated Activator Of Secreted Mmps And Invasion, 2018 Iowa State University
Matrix Metalloproteinase-14 Is A Mechanically Regulated Activator Of Secreted Mmps And Invasion, Amanda Haage, Dong Hyun Nam, Xin Ge, Ian C. Schneider
Ian C. Schneider
Matrix metalloproteinases (MMPs) are extracellular matrix (ECM) degrading enzymes and have complex and specific regulation networks. This includes activation interactions, where one MMP family member activates another. ECM degradation and MMP activation can be initiated by several different stimuli including changes in ECM mechanical properties or intracellular contractility. These mechanical stimuli are known enhancers of metastatic potential. MMP-14 facilitates local ECM degradation and is well known as a major mediator of cell migration, angiogenesis and invasion. Recently, function blocking antibodies have been developed to specifically block MMP-14, providing a useful tool for research as well as therapeutic applications. Here we ...

BACKGROUND: Italian pediatric antimicrobial prescription rates are among the highest in Europe. As a first step in an Antimicrobial Stewardship Program, we implemented a Clinical Pathway (CP) for Community Acquired Pneumonia with the aim of decreasing overall prescription of antibiotics, especially broad-spectrum.
MATERIALS AND METHODS: The CP was implemented on 10/01/2015. We collected antibiotic prescribing and outcomes data from children aged 3 months-15 years diagnosed with CAP from 10/15/2014 to 04/15/2015 (pre-intervention period) and from 10/15/2015 to 04/15/2016 (post-intervention period). We assessed antibiotic prescription differences pre- and post-CP, including rates ...
