Gut Dysbiosis And Age-Related Neurological Diseases In Females, Janelle M Korf, Bhanu P Ganesh, Louise D Mccullough

Faculty, Staff and Student Publications

Historically, females have been underrepresented in biological research. With increased interest in the gut microbiome and the gut-brain axis, it is important for researchers to pursue studies that consider sex as a biological variable. The composition of the gut microbiome is influenced by environmental factors, disease, diet, and varies with age and by sex. Detrimental changes in the gut microbiome, referred to as dysbiosis, is believed to influence the development and progression of age-related neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and stroke. Many are investigating the changes in microbial populations in order or to better understand …

Integrated Multilayer Omics Reveals The Genomic, Proteomic, And Metabolic Influences Of Histidyl Dipeptides On The Heart, Keqiang Yan, Zhanlong Mei, Jingjing Zhao, Md Aminul Islam Prodhan, Detlef Obal, Kartik Katragadda, Benjamin Doelling, David Hoetker, Dheeraj Kumar Posa

Internal Medicine, East Africa

Background: Histidyl dipeptides such as carnosine are present in a micromolar to millimolar range in mammalian hearts. These dipeptides facilitate glycolysis by proton buffering. They form conjugates with reactive aldehydes, such as acrolein, and attenuate myocardial ischemia-reperfusion injury. Although these dipeptides exhibit multifunctional properties, a composite understanding of their role in the myocardium is lacking.

Methods and Results: To identify histidyl dipeptide-mediated responses in the heart, we used an integrated triomics approach, which involved genome-wide RNA sequencing, global proteomics, and unbiased metabolomics to identify the effects of cardiospecific transgenic overexpression of the carnosine synthesizing enzyme, carnosine synthase (Carns), in …

Klif-Associated Cytoskeletal Proteins In Trypanosoma Brucei Regulate Cytokinesis By Promoting Cleavage Furrow Positioning And Ingression, Qing Zhou, Huiqing Hu, Ziyin Li

Faculty, Staff and Student Publications

Cytokinesis in the early divergent protozoan Trypanosoma brucei occurs from the anterior cell tip of the new-flagellum daughter toward the nascent posterior end of the old-flagellum daughter of a dividing biflagellated cell. The cleavage furrow ingresses unidirectionally along the preformed cell division fold and is regulated by an orphan kinesin named kinesin localized to the ingressing furrow (KLIF) that localizes to the leading edge of the ingressing furrow. Little is known about how furrow ingression is controlled by KLIF and whether KLIF interacts with and cooperates with other cytokinesis regulatory proteins to promote furrow ingression. Here, we investigated the roles …

Faculty, Staff and Student Publications

Invasive fungal infections continue to increase as at-risk populations expand. The high associated morbidity and mortality with fungal diseases mandate the continued investigation of novel antifungal agents and diagnostic strategies that include surrogate biomarkers. Biologic markers of disease are useful prognostic indicators during clinical care, and their use in place of traditional survival end points may allow for more rapid conduct of clinical trials requiring fewer participants, decreased trial expense, and limited need for long-term follow-up. A number of fungal biomarkers have been developed and extensively evaluated in prospective clinical trials and small series. We examine the evidence for these …

Role Of The Chemokine System In Liver Fibrosis: A Narrative Review, Kyle L Poulsen, Christina K Cajigas-Du Ross, Jarod K Chaney, Laura E Nagy

Faculty, Staff and Student Publications

BACKGROUND AND OBJECTIVE: Liver fibrosis is a disease with characteristics of an aberrant wound healing response. Fibrosis is commonly the end-stage for chronic liver diseases like alcohol-associated liver disease (ALD), metabolic-associated liver disease, viral hepatitis, and hepatic autoimmune disease. Innate immunity contributes to the progression of many diseases through multiple mechanisms including production of pro-inflammatory mediators, leukocyte infiltration and tissue injury. Chemokines and their receptors orchestrate accumulation and activation of immune cells in tissues and are associated with multiple liver diseases; however, much less is known about their potential roles in liver fibrosis. This is a narrative review of current …

Why Not Dipyridamole: A Review Of Current Guidelines And Re-Evaluation Of Utility In The Modern Era, Mahmoud Allahham, A Lerman, D Atar, Y Birnbaum

Faculty, Staff and Students Publications

Dipyridamole is an old anti-platelet and coronary vasodilator agent that inhibits platelet phosphodiesterase and increases interstitial adenosine levels. Its use in coronary artery disease (CAD) has fallen out of practice in the modern era with the advent of new anti-platelet agents, and most modern guidelines on the management of CAD either neglect to comment on its utility or outright recommend against it. The majority of the studies used in these guidelines are outdated and took place in an era when high doses of aspirin were used and statins were not widely utilized. There is growing evidence in rat models of …

Spontaneous Coronary Artery Dissection In A Young Male: A Case Report, Irene Tchuente M.D.

Advances in Clinical Medical Research and Healthcare Delivery

Abstract

Cardiovascular disease remains the number one cause of death worldwide. In recent years, there has been an increased focus on Coronary Artery Dissection due to the increasing number of young individuals without any cardiovascular risk factors presenting with chest pain. Many of these patients would also have elevated troponins and sometimes electrocardiogram changes suggestive of myocardial infarction. Many reported cases have been in women and only a handful of cases have been reported in men. Although some potential risk factors have been identified, more data is needed to support these hypotheses. Coronary Artery Dissection (CAD) mimics Acute Coronary Syndrome …

Management Of Right Sided Carcinoid Heart Failure, Ganesh Arun, Ismat Cheema, Lorrie Pennfield, Mohammed Raza, Erik Raborn, Ami Patel, Farhan Ali

Advances in Clinical Medical Research and Healthcare Delivery

Carcinoid heart disease is a rare complication of an already rare disease. This issue is theorized to be secondary to released proinflammatory molecules that deposit on the surfaces of heart valves. These molecules are released from the carcinoid tumor itself and manifest symptoms based on liver, lung and brain function. The detection of 5-HIAA, a breakdown source of serotonin, is useful for diagnosis. These deposits occur most commonly on the endocardium of valvular cusps and cardiac chambers. This case presents a 48 year old woman with echo findings of right heart failure in the setting of a carcinoid tumor. It …

Definition Of Germ Layer Cell Lineage Alternative Splicing Programs Reveals A Critical Role For Quaking In Specifying Cardiac Cell Fate, W Samuel Fagg, Naiyou Liu, Ulrich Braunschweig, Karen Larissa Pereira De Castro, Xiaoting Chen, Frederick S Ditmars, Steven G Widen, John Paul Donohue, Katalin Modis, William K Russell, Jeffrey H Fair, Matthew T Weirauch, Benjamin J Blencowe, Mariano A Garcia-Blanco

Faculty, Staff and Student Publications

Alternative splicing is critical for development; however, its role in the specification of the three embryonic germ layers is poorly understood. By performing RNA-Seq on human embryonic stem cells (hESCs) and derived definitive endoderm, cardiac mesoderm, and ectoderm cell lineages, we detect distinct alternative splicing programs associated with each lineage. The most prominent splicing program differences are observed between definitive endoderm and cardiac mesoderm. Integrative multi-omics analyses link each program with lineage-enriched RNA binding protein regulators, and further suggest a widespread role for Quaking (QKI) in the specification of cardiac mesoderm. Remarkably, knockout of QKI disrupts the cardiac mesoderm-associated alternative …
