Tsetse transmit African trypanosomiasis, which is a disease fatal to both humans and animals. A vaccine to protect against this disease does not exist so transmission control relies on eliminating tsetse populations. Although neurotoxic insecticides are the gold standard for insect control, they negatively impact the environment and reduce populations of insect pollinator species. Here we present a promising, environment-friendly alternative to current insecticides that targets the insect tyrosine metabolism pathway. A bloodmeal contains high levels of tyrosine, which is toxic to haematophagous insects if it is not degraded and eliminated. RNA interference (RNAi) of either the first two enzymes …

Introduction.

Concussions are of significant concern for athletic trainers, and there is a critical need to objectively and safely allow an athlete to return to play. In sports the objective is return as safely and soon as possible. Exertion is a consideration regarding progressing an athlete back to play. The ability to exert in cardiovascular and strength and conditioning contexts are two critical steps in most return to play protocols. Being able to make objective recommendations is urgently needed, as trial and error leads to unnecessary risk of eliciting symptoms and/or causing setbacks.

Role Of Antizyme Inhibitor Proteins In Cancers And Beyond, Venella Tulluri, Venkatesh V. Nemmara

College of Science & Mathematics Departmental Research

Polyamines are multivalent organic cations essential for many cellular functions, including cell growth, differentiation, and proliferation. However, elevated polyamine levels are associated with a slew of pathological conditions, including multiple cancers. Intracellular polyamine levels are primarily controlled by the autoregulatory circuit comprising two different protein types, Antizymes (OAZ) and Antizyme Inhibitors (AZIN), which regulate the activity of the polyamine biosynthetic enzyme ornithine decarboxylase (ODC). While OAZ functions to decrease the intracellular polyamine levels by inhibiting ODC activity and exerting a negative control of polyamine uptake, AZIN operates to increase intracellular polyamine levels by binding and sequestering OAZ to relieve ODC …

Faculty of Health Sciences, East Africa

tion residing in rural areas that have poor access to medical experts. Despite having a ridiculously huge, underserved population, very few African countries currently have any form of sustained and organized telemedicine practice, and even fewer have dedicated tele-neurology services. The ongoing COVID-19 pandemic has proved to be one of the most significant disruptors of vital sectors of human endeavor in modern times. In the healthcare sector, there is an increasing advocacy to deliver non-urgent care via telemedicine. This paper examined the current state of tele-neurology practice and infrastructural preparedness in sub-Saharan Africa. Currently, there is over 70% mobile phone …

An Analytical Expression For R50% Dependent On Ptv Surface Area And Volume: A Cranial Srs Comparison, Dharmin D. Desai, Ellis Lee Johnson, Ivan L. Cordrey

Radiation Medicine Faculty Publications

The intermediate dose spill for a stereotactic radiosurgery (SRS) plan can be quantified with the metric R50%, defined as the 50% isodose cloud volume (V_IDC50%) divided by the volume of the planning target volume (PTV). By coupling sound physical principles with the basic definition of R50%, we derive an analytical expression for R50% for a spherical PTV. Our analytical expression depends on three quantities: the surface area of PTV (SA_PTV), the volume of PTV (V_PTV), and the distance of dose drop-off to 50% (Δr). The value of ∆r was obtained from a simple set …

Structural Insights Into The Disruption Of Tnf-Tnfr1 Signalling By Small Molecules Stabilising A Distorted Tnf, David Mcmillan, Carlos Martinez-Fleites, John Porter, David Fox, Rachel E. Davis, Prashant Mori, Tom Ceska, Bruce Carrington, Alastair Lawson, Tim Bourne, James O'Connell

Faculty Publications

Tumour necrosis factor (TNF) is a trimeric protein which signals through two membrane receptors, TNFR1 and TNFR2. Previously, we identified small molecules that inhibit human TNF by stabilising a distorted trimer and reduce the number of receptors bound to TNF from three to two. Here we present a biochemical and structural characterisation of the small molecule-stabilised TNF-TNFR1 complex, providing insights into how a distorted TNF trimer can alter signalling function. We demonstrate that the inhibitors reduce the binding affinity of TNF to the third TNFR1 molecule. In support of this, we show by X-ray crystallography that the inhibitor-bound, distorted, TNF …

This study aimed to investigate the annual incidence of parapharyngeal and retropharyngeal abscess (PRPA) based on 10-year population-based data. Patients with PRPA were identified from the Taiwan Health Insurance Research Database, a database of all medical claims of a randomly selected, population-representative sample of over two million enrollees of the National Health Insurance system that covers over 99% of Taiwan’s citizens. During 2007–2016, 5779 patients received a diagnosis of PRPA. We calculated the population-wide incidence rates of PRPA by sex and age group (20–44, 45–64, and >64) as well as in-hospital mortality. The annual incidence rate of PRPA was 2.64 …

"Trauma To The Eye"-A Low Fidelity Resident Teaching Module For Identifying And Treating A Retrobulbar Hematoma., Jared Raikin, R. Hall, Dimitrios Papanagnou, Md

Department of Emergency Medicine Faculty Papers

Introduction: A retrobulbar hematoma (RH) is a serious time-dependent diagnosis due to its potential for permanent damage of the optic nerve, resulting in blindness. Emergency medicine (EM) physicians face the challenge of recognizing this time-sensitive injury and treating it before irreversible damage occurs. Due to its relative infrequency in the emergency department, residents may not have adequate experience in recognizing and treating RH.

Methods: This educational intervention outlined a simulated scenario that we developed to educate EM residents to diagnose RH and perform an emergent lateral canthotomy and cantholysis (LCC). Participating residents were asked to obtain a history and perform …

School of Graduate Studies Faculty Publications

BACKGROUND: Poly(ADP-ribose) polymerase (PARP) inhibitors (eg, olaparib) are effective against BRCA-mutated cancers at/near maximum tolerated doses by trapping PARP-1 on damaged chromatin, benefitting only small patient proportions. The benefits of targeting non-DNA repair aspects of PARP with metronomic doses remain unexplored. METHODS: Colon epithelial cells or mouse or human bone marrow (BM)-derived-myeloid-derived suppressor cells (MDSCs) were stimulated to assess the effect of partial PARP-1 inhibition on inflammatory gene expression or immune suppression. Mice treated with azoxymethane/four dextran-sulfate-sodium cycles or mice bred into PARP-1 or treated with olaparib were used to examine the role of PARP-1 in colitis-induced or spontaneous colon …

Adrenal Vein Cortisol To Metanephrine Ratio For Localizing Acth-Independent Cortisol-Producing Adenoma: A Case Report, Rishi Raj, Philip A. Kern, Neelima Ghanta, Edilfavia M. Uy, Kamyar Asadipooya

Internal Medicine Faculty Publications

Context: Finding the source of adrenocorticotropic hormone (ACTH)-independent cortisol-producing adenoma in the patients with subclinical Cushing syndrome (SCS) and bilateral adrenal nodules is sometimes challenging. Computed tomography (CT) and positron emission tomography are helpful, but adrenal venous sampling (AVS) is the gold standard approach. However, interpretation of AVS is important to improve the accuracy of decision-making for surgery. We report a case and review of the literature to assess the benefit of using adrenal vein cortisol to metanephrine ratio to determine the source of cortisol production in SCS and bilateral nodules.

Evidence Acquisition: Three authors searched PubMed for data on …

Manganese Exposure In Juvenile C57bl/6 Mice Increases Glial Inflammatory Responses In The Substantia Nigra Following Infection With H1n1 Influenza Virus., Collin M Bantle, C Tenley French, Jason E Cummings, Shankar Sadasivan, Kevin Tran, Richard A Slayden, Richard Jay Smeyne, Ronald B Tjalkens

Farber Institute for Neuroscience Faculty Papers

Infection with Influenza A virus can lead to the development of encephalitis and subsequent neurological deficits ranging from headaches to neurodegeneration. Post-encephalitic parkinsonism has been reported in surviving patients of H1N1 infections, but not all cases of encephalitic H1N1 infection present with these neurological symptoms, suggesting that interactions with an environmental neurotoxin could promote more severe neurological damage. The heavy metal, manganese (Mn), is a potential interacting factor with H1N1 because excessive exposure early in life can induce long-lasting effects on neurological function through inflammatory activation of glial cells. In the current study, we used a two-hit model of neurotoxin-pathogen …

Malaria In Southern Venezuela: The Hottest Hotspot In Latin America, Maria Eugenia Grillet, Jorge E. Moreno, Juan V. Hernández-Villena, Maria F. Vincenti-González, Oscar Noya, Adriana Tami, Alberto Paniz-Mondolfi, Martin Llewellyn, Rachel Lowe, Ananias A. Escalante, Jan E. Conn

Harold W. Manter Laboratory of Parasitology: Library Materials

Malaria elimination in Latin America is becoming an elusive goal. Malaria cases reached a historical ~1 million in 2017 and 2018, with Venezuela contributing 53% and 51% of those cases, respectively. Historically, malaria incidence in southern Venezuela has accounted for most of the country’s total number of cases. The efficient deployment of disease prevention measures and prediction of disease spread to new regions requires an in-depth understanding of spatial heterogeneity on malaria transmission dynamics. Herein, we characterized the spatial epidemiology of malaria in southern Venezuela from 2007 through 2017 and described the extent to which malaria distribution has changed country-wide …

Visit-To-Visit Blood Pressure Variability And Sleep Architecture, Xiaoyue Liu, Jeongok Logan, Younghoon Kwon, Jennifer M. Lobo, Hyojung Kang, Min-Woong Sohn

Health Management and Policy Faculty Publications

Visit‐to‐visit blood pressure (BP) variability (BPV) is an independent risk factor of cardiovascular disease (CVD). Sleep architecture characterizes the distribution of different stages of sleep and may be important in CVD development. We examined the association between visit‐to‐visit BPV and sleep architecture using in‐lab polysomnographic data from 3,565 patients referred to an academic sleep center. BPV was calculated using the intra‐individual coefficient of variation of BP measures collected 12 months before the sleep study. We conducted multiple linear regression analyses to assess the association of systolic and diastolic BPV with sleep architecture—rapid eye movement (REM) and non‐rapid eye movement (NREM) …

Appalachian Caregiver Perspectives On Childhood Gun Safety In The Home, Dannell Boatman

Journal of Appalachian Health

Background: Childhood gun injuries pose a critical public health challenge. For children, unintentional gun injury deaths primarily occur in the home where parents or other adult guardians, referred to as caregivers hereafter, are responsible for safety. While the American Academic of Pediatrics recommends not having guns in areas where children live and play, firearms are often viewed as normative and fill an important role in many homes. This is particularly true in more rural areas, such as Appalachia, where there is a high density of gun ownership. Additional research is needed to understand rural caregivers’ current gun safety practices in …
