Modulator Therapy For Cystic Fibrosis: An Exploration Of Current Research, Jessalyn Rombocos 2020 Liberty University

Modulator Therapy For Cystic Fibrosis: An Exploration Of Current Research, Jessalyn Rombocos

Senior Honors Theses

Developing a drug therapy that addresses the root cause of cystic fibrosis (CF) by increasing CFTR protein levels has long been a research challenge. After genetic therapy failed because a suitable delivery system could not be found, researchers began searching for small organic molecules that could act as chaperones for CFTR. These molecules, known as modulators, allowed CFTR to be assembled correctly and function similarly to wild type CFTR. Since 2012, four modulator drugs have been developed, tested, and approved by the FDA. In October 2019, Trikafta was approved as the first triple-combination modulator drug and has completely revolutionized CF ...


Renal Safety And Racial Disparity In Patients On Antiviral Treatment For Chronic Hepatitis B, Matthew Miller, Sindhuri Benjaram, Raya Kutaimy, Paul Naylor, Elizabeth May, Murray Ehrinpreis, Milton Mutchnick 2020 Wayne State University

Renal Safety And Racial Disparity In Patients On Antiviral Treatment For Chronic Hepatitis B, Matthew Miller, Sindhuri Benjaram, Raya Kutaimy, Paul Naylor, Elizabeth May, Murray Ehrinpreis, Milton Mutchnick

Medical Student Research Symposium

Background:

Many African Americans (AA) are chronically infected with Hepatitis B (HBV). While antiviral therapy is highly effective, clinical trials suggest a treatment-related decline in kidney function is possible. Given that chronic HBV predominately affects Asians worldwide, most studies have contained few AA patients. We evaluated these treatment-related kidney function changes in our predominately AA patient population.

Methods:

From 225 HBV patients, we identified 42 patients who were not co-infected with HIV or HCV, had a recent visit, and at least one earlier visit (before Jan 2017). If on treatment with antivirals it must have been for at least 2 ...

A Short Remark On Multipurpose Laser Therapy “Helios” In Ukraine And Its Potential Application For Treatment Of Neurology Disorders, Florentin Smarandache, Volodymyr Krasnoholovets, Victor Christianto, Rizha Vitania, The Houw Liong

Mathematics and Statistics Faculty and Staff Publications

However, a truly multipurpose laser therapy method is very rarely available. Here we introduce a multipurpose laser therapy device in Ukraine, which is capable to take care a multitude of diseases. It is called “Helios”, by one of us (VK). We also give a case where a patient who suffered from Covid-19 has been treated successfully until he is recovered to healthy condition. In the last section we also discuss potential future application of Helios for other fields; i.e. neurology disorders.


Clincial Translational Science Research Of The Functional Role Of Large Conductance Potassium Channels In Selective Destruction Of Triple Negative Breast Cancer Cells, Gina Sizemore 2020 West Virginia University

Clincial Translational Science Research Of The Functional Role Of Large Conductance Potassium Channels In Selective Destruction Of Triple Negative Breast Cancer Cells, Gina Sizemore

Graduate Theses, Dissertations, and Problem Reports

ABSTRACT

The preliminary background that puts this research into context is threefold; it is the aggressive nature of triple negative breast cancer (TNBC), the complexity surrounding its pathology, and the significant lack of targeted treatment for this disease. To clarify the focus of my research, I have concentrated on identifying a targeted treatment for TNBC. In the process, I have identified cycles of reciprocity between treatment, clinical diagnosis, staging, and pathology that will be addressed in smaller papers. However, the weight of this work is in the discovery of a novel target for triple negative breast cancer. The value of ...

Evaluation Of Tumor Necrosis Factor Alpha In Sleep-Deprived Menopausal- Induced Rats And The Impact On Bone Health, Nicole Ellsworth, Dwight Curry Iii, Cj Deleon, Frank Frisch

Student Scholar Symposium Abstracts and Posters

Post-menopausal osteoporosis as a consequence of estrogen depletion is a growing concern for women in the United States. As more women take on executive positions and experience sleep deprivation, there is the potential for up regulation of pro-inflammatory cytokines, such as tumor necrosis factor alpha. It follows that the homeostatic imbalance of osteoclastic and osteoblastic activity leads to a greater risk of disease. Bisphosphonates generally, and Zolendronate specifically works by decreasing the number of osteoclasts. This current study investigated the impact of Zolendronate on the concentrations of tumor necrosis factor alpha-type (TNFɑ) in 32 ovariectomized Wistar rats. Throughout a five ...

The human voltage-gated proton channel [Hv1(1) or VSDO(2)] plays an important role in the human innate immune system. Its structure differs considerably from those of other cation channels. It is built solely of a voltage-sensing domain and thus lacks the central pore domain, which is essential for other cation channels. Here, we determined the solution structure of an N- and C-terminally truncated human Hv1 (Δ-Hv1) in the resting state by nuclear magnetic resonance (NMR) spectroscopy. Δ-Hv1 comprises the typical voltage-sensing antiparallel four-helix bundle (S1–S4) preceded by an amphipathic helix (S0). The solution structure corresponds to an intermediate ...

Prostate cancer (PCa) is the most common malignancy in men and is the leading cause of cancer-related male mortality. A disulfide cyclic peptide ligand [CTVRTSADC] 1 has been previously found to target extra domain B of fibronectin (EDB-FN) in the extracellular matrix that can dierentiate aggressive PCa from benign prostatic hyperplasia. We synthesized and optimized the stability of ligand 1 by amide cyclization to obtain [KTVRTSADE] 8 using Fmoc/tBu solid-phase chemistry. Optimized targeting ligand 8 was found to be stable in phosphate buered saline (PBS, pH 6.5, 7.0, and 7.5) and under redox conditions, with a ...


Hexavalent Chromium-Induced Cytotoxicity And Mutagenicity: A Study Of Protection By Ascorbic Acid And Epigallocatechin Gallate, Timothy P. Mayotte 2019 Olivet Nazarene University

Hexavalent Chromium-Induced Cytotoxicity And Mutagenicity: A Study Of Protection By Ascorbic Acid And Epigallocatechin Gallate, Timothy P. Mayotte

Honors Program Projects

Hexavalent chromium, or Cr(VI), is a potent oxidizer and known carcinogen, that is found at varying levels in the water sources of more than 200 million Americans. However, the exact mechanism of carcinogenicity remains unknown, and though the government currently regulates total chromium levels, they have yet to determine a permissible exposure limit for Cr(VI). Moreover, there is currently no preventative treatment for Cr(VI). Because of Cr(VI)’s strong oxidative power, we hypothesized that it causes DNA mutation and cell death via oxidation and that antioxidants could prevent this from occurring. To test this, we first ...

Although the Ub-binding domain in ABIN proteins and NEMO (UBAN) is highly conserved, UBAN-containing proteins exhibit different Ub-binding properties, resulting in their diverse biological roles. Post-translational modifications further control UBAN domain specificity for poly-Ub chains. However, precisely, how the UBAN domain structurally confers such functional diversity remains poorly understood. Here we report crystal structures of ABIN-1 alone and in complex with one or two M1-linked di-Ub chains. ABIN-1 UBAN forms a homo-dimer that provides two symmetrical Ub-binding sites on either side of the coiled-coil structure. Moreover, crystal structures of ABIN1 UBAN in complex with di-Ub chains reveal a concentration-dependency of ...

Brain tumors are the most common childhood solid malignancy, and because of remarkable advances in treating many cancers outside of the brain, they have become the leading cause of cancer mortality in children. Ependymomas are a class of brain tumors which can be further subdivided into three groups based upon their location and genetic features. Of the three classes, supratentorial ependymomas are the only subgroup known to be marked by an oncogenic driver gene, which consists of a fusion mutation between the C11orf95 and RELA genes. C11orf95-RELA positive tumors are the most aggressive and lethal of ...

Role Of Serum Biomarkers In Early Detection Of Diabetic Cardiomyopathy In The West Virginian Population, Adam Shaver, Alexandra Nichols, Ellen A. Thompson, Amrita Mallick, Nandini Manne, Shanmuga Sundaram, Joseph I. Shapiro Md, Komal Sodhi

Joseph I Shapiro MD

Objectives: Diabetic cardiomyopathy (DCM) is an established complication of diabetes mellitus. In West Virginia, the especially high incidence of diabetes and heart failure validate the necessity of developing new strategies for earlier detection of DCM. Since most DCM patients remain asymptomatic until the later stages of the disease when the fibrotic complications become irreversible, we aimed to explore biomarkers that can identify early-stage DCM.

Methods: The patients were grouped into 4 categories based on clinical diabetic and cardiac parameters: Control, Diabetes (DM), Diastolic dysfunction (DD), and Diabetes with diastolic dysfunction (DM+DD), the last group being the preclinical DCM group ...

An Investigation Of Stimulants: Reviewing Their Effects On The Brain, Including Memory And Microglia, Michael Douchey

Student Research and Creative Activity Fair

Stimulants are a class of drugs that have a variety of effects on the brain, including changes in receptor activity in the brain areas responsible for- memory, attention, emotion, motor control, and the reward pathway. Stimulants may be generally classified by their availability. For example, prescription stimulants, which include drugs such as methylphenidate (Concerta™, Ritalin™) and mixed amphetamine salts (Adderall™), must be prescribed by medical professionals. Another regulated stimulant, albeit one available without a prescription, is nicotine; a highly addictive chemical that is age-restricted by the U.S. federal government. Nicotine is found in tobacco products, and in tobacco-free alternatives ...

Embryonic Stem Cell-Derived Exosomes Increase The Antiproliferative Activity Of Doxorubicin In Breast Cancer, Alexander M. Hirsch 2019 Virginia Commonwealth University

Embryonic Stem Cell-Derived Exosomes Increase The Antiproliferative Activity Of Doxorubicin In Breast Cancer, Alexander M. Hirsch

Theses and Dissertations

The field of cancer research has grown immensely in recent decades and has led to a better understanding of the causes of the disease, as well as greatly improved treatment for various types of cancers, especially breast cancer. One of the most effective treatments involves the chemotherapeutic drug doxorubicin (DOX). DOX is an effective tool against all types of breast cancer, especially against triple negative breast cancer. However, DOX causes adverse side effects that include damage to the heart and skeletal muscle, particularly above specific cumulative doses. Recent evidence suggests that embryonic stem cell-derived (ES) exosomes, nanoscale extracellular vesicles that ...

Family Medicine Resident Education On Perioperative Management Of Patients On Anticoagulation, Hanna Mathers

Family Medicine Clerkship Student Projects

Family Medicine residents at CMMC in Lewiston, Maine manage patients in an outpatient clinic as well as on an inpatient family medicine teaching service. Many patients in the community are anticoagulated for native valve atrial fibrillation and undergo surgical procedures both in the inpatient and outpatient setting. Residents are often asked on to determine the necessity and timing of anticoagulation discontinuation for patients that they see. With patients on newer oral anticoagulants and various degrees of risk, it can be a challenge to make an informed choice. Residents have found that they would feel more confident in perioperative management of ...


Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley 2019 The University of Akron

Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley

Williams Honors College, Honors Research Projects

Cuprizone is a copper chelator that induces demyelination in the central nervous system when fed to mice. This compound is thought to target Complex IV and disrupt mitochondrial metabolism leading to loss of myelin-producing oligodendrocytes. In this proposal, we further examine the chemical and toxicological properties of cuprizone. Immunofluorescence imaging and microarray data on MO3.13 cells treated with cuprizone revealed the possibility of alterations in lysosomal function, as well as mitochondrial disruption via mTOR and Electron Transport Chain (ETC) related pathways. Cell viability assays conducted suggest that addition of Branched-Chain Amino Acids, most commonly used from literature, leucine, can ...
