Hif Expression In Clear-Cell Renal Cell Carcinoma (Ccrcc) Tumors Of Adults With And Without Obstructive Sleep Apnea (Osa), Olivia Heppell, Carlos Guerra Londono, Nilesh Gupta
Medical Student Research Symposium
Introduction: Upregulation of hypoxia-inducible factors (HIF) is an important pathological feature shared by clear cell renal cell carcinoma (ccRCC) and obstructive sleep apnea (OSA). However, it is unclear whether OSA alters the pathogenesis of ccRCC via HIF expression.
Methods: A retrospective cohort of adults undergoing nephrectomy for ccRCC was identified electronically (IRB#16040-1). The diagnosis of OSA was established with preoperative STOP-BANG scores or polysomnography. A consecutive sample of 20 individuals with and 20 without OSA was selected. Clinical characteristics and pathology results were reviewed. Resected tumor sections were immunohistochemically stained for HIF-1& HIF-2 at antibody dilutions of 1:150. Intensity and …

Electronic cigarettes are battery powered devices that use a vape-liquid to produce a vapor that is inhaled. A consequence of the rise in e-cigarette usage was the 2019 emergence of a vaping-induced respiratory disease denoted as 'e-cigarette or vaping use-associated lung injury' (EVALI). One of the suspected causes of EVALI is Vitamin E Acetate (VEA), which was found to be a diluent in certain illicit vape-pens, whereas nicotine is commonly diluted in equal parts propylene glycol and vegetable glycerin (PG:VG). The prevalent use of e-cigarettes and the emergence of a novel illness has made understanding how e-cigarette vapors affect our …

Background: Adult asthma is complex and incompletely understood. Plasma proteomics is an evolving technique that can both generate biomarkers and provide insights into disease mechanisms. We aimed to identify plasma proteomic signatures of adult asthma.
Methods: Protein abundance in plasma was measured in individuals from the Agricultural Lung Health Study (ALHS) (761 asthma, 1095 non-case) and the Atherosclerosis Risk in Communities study (470 asthma, 10,669 non-case) using the SOMAScan 5K array. Associations with asthma were estimated using covariate adjusted logistic regression and meta-analyzed using inverse-variance weighting. Additionally, in ALHS, we examined phenotypes based on both asthma and seroatopy (asthma with …
Systemic Review Of Clot Retraction Modulators, Alaina Guilbeau, Rinku Majumder
Systemic Review Of Clot Retraction Modulators, Alaina Guilbeau, Rinku Majumder
School of Graduate Studies Faculty Publications
Through a process termed clot retraction, platelets cause thrombi to shrink and become more stable. After platelets are activated via inside-out signaling, glycoprotein αIIbβIII binds to fibrinogen and initiates a cascade of intracellular signaling that ends in actin remodeling, which causes the platelet to change its shape. Clot retraction is also important for wound healing. Although the detailed molecular biology of clot retraction is only partially understood, various substances and physiological conditions modulate clot retraction. In this review, we describe some of the current literature pertaining to clot retraction modulators. In addition, we discuss compounds from Cudrania trucuspidata, Arctium lappa, …

The cornea and cranial dura mater share sensory innervation. This link raises the possibility that pathological impulses mediated by corneal injury may be transmitted to the cranial dura, trigger dural perivascular/connective tissue nociceptor responses, and induce vascular and stromal alterations affecting dura mater blood and lymphatic vessel functionality. In this study, using a mouse model, we demonstrate for the first time that two weeks after the initial insult, alkaline injury to the cornea leads to remote pathological changes within the coronal suture area of the dura mater. Specifically, we detected significant pro-fibrotic changes in the dural stroma, as well as …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers
The baroreflex is a multi-input, multi-output physiological control system that regulates blood pressure by modulating nerve activity between the brainstem and the heart. Existing computational models of the baroreflex do not explicitly incorporate the intrinsic cardiac nervous system (ICN), which mediates central control of heart function. We developed a computational model of closed-loop cardiovascular control by integrating a network representation of the ICN within central control reflex circuits. We examined central and local contributions to the control of heart rate, ventricular functions, and respiratory sinus arrhythmia (RSA). Our simulations match the experimentally observed relationship between RSA and lung tidal volume. …

Oxygen Deprivation Masks For Training, Brittany M. Hanlon
Student Publications
Oxygen deprivation masks are being advertised towards athletes as a piece of fitness equipment that can simulate the effects of high altitude, as well as a respiratory muscle training device. Studies that investigated the claims as to whether ODMs increased VO2max and improved endurance were looked into. Experimental data did not find that the use of these masks increased VO2max, nor was there any supporting data to prove that it improved endurance. The function of ODMs as a training tool to increase respiratory muscle strength was also examined. There were contradicting results between the three different studies examined. One study …

Jnk And Nf-Κb Cell Signaling Pathways In Cardiovascular Disease Present Potential Targets For Curcumin Therapy, Mary Richfield
Jnk And Nf-Κb Cell Signaling Pathways In Cardiovascular Disease Present Potential Targets For Curcumin Therapy, Mary Richfield
Senior Honors Theses
Curcumin (diferuloylmethane) is a compound derived from the rhizomes of Curcumin longa that has been long used for medicinal purposes. Curcumin alleviates the pathology of cardiovascular diseases, including atherosclerosis, aneurysm, and cardiomyopathy. The mechanism of curcumin therapy is under active research. The NF-κB and JNK pathways are two that curcumin interacts with to block inflammatory processes, apoptosis, and fibrotic tissue remodeling to prevent the pathologies of cardiovascular disease. While curcumin has demonstrated powerful mediation of cardiovascular disease, its bioavailability in body tissues is limited due to the instability and hydrophobicity of its structure. Further work is underway to stabilize …

Saha Cardiovascular Research Center Faculty Publications
Aortic aneurysms and dissections are life-threatening conditions that have a high risk for lethal bleeding and organ malperfusion. Many studies have investigated the molecular basis of these diseases using mouse models. In mice, ex vivo, in situ, and ultrasound imaging are major approaches to evaluate aortic diameters, a common parameter to determine the severity of aortic aneurysms. However, accurate evaluations of aortic dimensions by these imaging approaches could be challenging due to pathological features of aortic aneurysms. Currently, there is no standardized mode to assess aortic dissections in mice. It is important to understand the characteristics of each approach for …

Physical inactivity has been a public health problem worldwide for more than a decade. Of those who are physically active, a substantial percentage engage solely in low or very low physical activity (PA) levels. In the last 3 decades, the prevalence of PA in the United States has decreased with approximately 80% of adults not meeting the recommended guidelines for aerobic and muscle strengthening PA. The PA levels of youth have dramatically decreasedwith 85% of adolescents reporting no PA. Regular PA participation can aid in preventing chronic diseases. A strong inverse dose-response relationship exists between PA and the incidence of …

BACKGROUND: Niacin has modest but overall favorable effects on plasma lipids by increasing high density lipoprotein cholesterol (HDL-C) and lowering triglycerides. Clinical trials, however, evaluating niacin therapy for prevention of cardiovascular outcomes have returned mixed results. Recent evidence suggests that the HDL proteome may be a better indicator of HDL's cardioprotective function than HDL-C. The objective of this study was to evaluate the effect of niacin monotherapy on HDL protein composition and function.
METHODS: A 20-week investigational study was performed with 11 participants receiving extended-release niacin (target dose = 2 g/day) for 16-weeks followed by a 4-week washout period. HDL …

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 …

Introduction
Elevated heart rate (HR) and low HR variability (HRV) are indicators of increased sympathetic tone and cardiovascular risk. Here, we assess the effect of one night of sleep deprivation and a subsequent night of recovery sleep on HR and HRV in healthy males versus females.
Methods
Fifty-nine subjects (29.5±8.5y, n=35 female) completed a 4-day/3-night laboratory study. Subjects had a baseline sleep opportunity (22:00–08:00), followed by 38h of sleep deprivation, and a recovery sleep opportunity (22:00–08:00). EKG was monitored via Holter monitors to measure HR and the pNN50 and rMMSD variables of HRV. Time points used for analyses included 09:00–09:20 …
