Psychology Articles

Introduction Cognitive impairment is common following stroke and can increase disability and levels of dependency of patients, potentially leading to greater burden on carers and the healthcare system. Effective cardiovascular risk factor control through secondary preventive medications may reduce the risk of cognitive decline. However, adherence to medications is often poor and can be adversely affected by cognitive deficits. Suboptimal medication adherence negatively impacts secondary prevention targets, increasing the risk of recurrent stroke and further cognitive decline. The aim of this study is to profile cognitive function and secondary prevention, including adherence to secondary preventive medications and healthcare usage, 5 ...


Delineating A Cardioprotective Pathway For Trp Channel-Induced Nitric Oxide Production In Diabetic Cardiomyocytes, Erik Hopkins, Spencer R. Andrei, Manasi A. Agrawal, Monica Ghosh, Derek Damron Dr. 2017 Kent State University - Kent Campus

Delineating A Cardioprotective Pathway For Trp Channel-Induced Nitric Oxide Production In Diabetic Cardiomyocytes, Erik Hopkins, Spencer R. Andrei, Manasi A. Agrawal, Monica Ghosh, Derek Damron Dr.

Undergraduate Research Symposium

Background: Transient Receptor Potential (TRP) channel stimulation induces the up-regulation of several downstream mediators that are well understood to be cardioprotective in response to ischemic injury in the heart. However, since the discovery of this cardioprotective pathway is completely novel in nature, the extent to which it is modified in the setting of diabetes presents an intriguing translational interest. We hypothesized that the TRP-induced upregulation of this cardioprotective axis is compromised in diabetes.

Methods: CMs isolated from normal and diabetic mice were treated with the TRPA1 agonist, AITC, or the TRPV1 agonist, capsaicin, in the presence or absence of TRPA1 ...


Trpa1 Activation Elicits Post-Translational Modifications Of Akt And Enos In Cardiomyocytes, Ryan Pasquino, Spencer Andrei, Monica Ghosh, Manasi Agrawal, Derek Damron 2017 Kent State University

Trpa1 Activation Elicits Post-Translational Modifications Of Akt And Enos In Cardiomyocytes, Ryan Pasquino, Spencer Andrei, Monica Ghosh, Manasi Agrawal, Derek Damron

Undergraduate Research Symposium

Background: Recently, our lab was the first to identify the functional presence of transient receptor potential (TRP) channels of the ankyrin 1 subtype (TRPA1) in mouse cardiomyocytes (CMs). However, the extent to which TRPA1 mediates signaling events in cardiac tissue has yet to be fully determined. Based upon investigations completed in other tissue types in the body, we hypothesized that TRPA1 activation will lead to Akt and eNOS activation in CMs.

Methods: CMs were untreated or treated with the TRPA1-specific agonist, allyl isothiocyanate (AITC), in the presence of absence of Akt inhibitor (LY294002) or eNOS inhibitor (L-NAME) and prepared for ...


Nitric Oxide Bioavailability In Diabetic Cardiomyocytes: The Role Of Propofol In Superoxide Scavenging, Kayla N. Hamdan, Spencer R. Andrei, Derek S. Damron 2017 Kent State University

Nitric Oxide Bioavailability In Diabetic Cardiomyocytes: The Role Of Propofol In Superoxide Scavenging, Kayla N. Hamdan, Spencer R. Andrei, Derek S. Damron

Undergraduate Research Symposium

Background: The reaction of NO with superoxide anion to form peroxynitrite has been implicated as a potential mechanism contributing to the limited NO bioavailability observed in diabetes. Furthermore, there is little evidence outlining the effects of intravenous anesthetic, propofol, on NO bioavailability in cardiomyocytes (CMs) isolated from diabetic mice. We hypothesized that propofol would act as a superoxide scavenger, thereby increasing NO bioavailability.

Methods: For NO, superoxide and peroxynitrite measurements, freshly isolated control and diabetic CMs were incubated in the presence or absence of propofol with NO, superoxide (DHE) or peroxynitrite (HKG) fluorescent probes. Fluorescence was measured using either fluorescence ...

Venoarterial Extracorporeal Membrane Oxygenation For Cardiogenic Shock: A Retrospective Analysis Based On The Etiology Of Shock, Andrew Burchett, Thomas Tribble, Richard Charnigo, Susan Smyth, Maya Guglin

The VAD Journal

Abstract:

Background: We performed a retrospective analysis to evaluate the efficacy of VA-ECMO support in cardiogenic shock based on various etiologies.

Methods: We retrospectively analyzed 99 patients supported with VA-ECMO from January 1, 2012 to January 1, 2015. Outcomes included survival to discontinuation of VA-ECMO support and survival to hospital discharge. The etiologies of cardiogenic shock included cardiac arrest (CPR), acute myocardial infarction (AMI), decompensated congestive heart failure (CHF), pulmonary embolism (PE), right ventricular failure (RVF) not secondary to an acute pulmonary embolism, and post-cardiotomy syndrome (PCS). The PCS group was used as a reference group; odds ratios were estimated ...


P23. Elucidation Of The Signaling Pathway Of Mertk, Kyle Taruc 2017 Western University

P23. Elucidation Of The Signaling Pathway Of Mertk, Kyle Taruc

Western Research Forum

Background

Mer Tyrosine Kinase (MERTK) is a receptor which mediates efferocytosis – removal of apoptotic cells by phagocytes such as macrophages. MERTK plays a critical role in homeostasis, with mutations in MERTK associated with the development and progression of atherosclerosis, the buildup of cholesterol-laden plaque in the sub-arterial space. Indeed, one MERTK allele is associated with 66% (heterozygous) to 75% (homozygous) protection from atherosclerosis, while other alleles and SNP’s pre-dispose to atherosclerosis and autoimmunity. Complications resulting from atherosclerosis, including heart attack and stroke, are currently the second leading cause of mortality in Canada. Despite the importance of MERTK in atherosclerosis ...

Over the last few decades, there has been a shift in the classroom from a teacher-centered learning environment, with its emphasis on content delivery, to a student-centered environment focused on inquiry learning (http://www.nsta.org/docs/ PositionStatement_Scienti cInquiry.pdf). With the Next Generation Science Standards (NGSS, 2012) being adopted by many states, students are no longer passive listeners, but actively participate in and initiate class discussions (Weimar, 2013). Additionally, recent technological advances have allowed students to acquire information from sources such as the internet which no longer necessitates the teacher giving lectures (Silver- thorn, 2006). The more student-centered learning ...

Hypertension is one of the most common and important health problems worldwide.1 It has been estimated that 29% of the world's adult population, or 1.56 billion people, will have hypertension by the year 2025.2The prevalence of high blood pressure and its adverse consequences result in a heavy burden for hypertensive patients from high‐, middle‐, and low‐income countries.2, 3 Many monogenic causes of hypertension have been reported. However, determining the causes of essential hypertension has been hampered because it is a complex disorder with genetic, epigenetic, and environmental determinants. Among numerous environmental factors, sodium ...


Up-Regulation Of Junctophilin-2 Prevents Er Stress And Apoptosis In Hypoxia/Reoxygenation-Stimulated H9c2 Cells, Zijun Su 2017 The University of Western Ontario

Up-Regulation Of Junctophilin-2 Prevents Er Stress And Apoptosis In Hypoxia/Reoxygenation-Stimulated H9c2 Cells, Zijun Su

Electronic Thesis and Dissertation Repository

Ischemic heart disease is the leading cause of death, and reperfusion which can restore blood flow is the primary therapy. However, reperfusion can induce further damage to cardiomyocytes, a condition described as ischemia-reperfusion (I/R) injury. I/R is now recognized as a combination determining the final myocardial infarction size. Although the mechanisms underlying I/R-induced cardiac injury remain incompletely understood, emerging evidence suggests that intracellular Ca2+ mishandling during I/R plays a key role in cell death. Junctophilin-2 (JPH2) is a junctional membrane-binding structural protein. It mechanically maintains the fixed distance between the T-tubule and the sarcoplasmic reticulum ...

BACKGROUND: Cardiometabolic (CM) risk factors are heritable and cluster in individuals. We hypothesized that CM risk factors are associated with multiple shared and unique mRNA and microRNA (miRNA) signatures. We examined associations of mRNA and miRNA levels with 6 CM traits: body mass index, HDL-cholesterol and triglycerides, fasting glucose, and systolic and diastolic blood pressures through cross-sectional analysis of 2812 Framingham Heart Study who had whole blood collection for RNA isolation for mRNA and miRNA expression studies and who consented to genetic research. We excluded participants taking medication for hypertension, dyslipidemia, or diabetes. We measured mRNA (n = 17,318; using ...

BACKGROUND: Impaired left atrial (LA) mechanical function is present in hypertension and likely contributes to various complications, including atrial arrhythmias, stroke, and heart failure. Various antihypertensive drug classes exert differential effects on central hemodynamics and left ventricular function. However, little is known about their effects on LA function.

METHODS AND RESULTS: We studied 212 subjects with hypertension and without heart failure or atrial fibrillation. LA strain was measured from cine steady-state free-precession cardiac MRI images using feature-tracking algorithms. In multivariable models adjusted for age, sex, race, body mass index, blood pressure, diabetes mellitus, LA volume, left ventricular mass, and left ...

OBJECTIVE: To determine whether a clinically-utilised IL-1 receptor antagonist, anakinra, reduces renal inflammation, structural damage and blood pressure (BP) in mice with established hypertension. METHODS: Hypertension was induced in male mice by uninephrectomy, deoxycorticosterone acetate (2.4mg/d,s.c.) and replacement of drinking water with saline (1K/DOCA/salt). Control mice received uninephrectomy, a placebo pellet and normal drinking water. 10days post-surgery, mice commenced treatment with anakinra (75mg/kg/d, i.p.) or vehicle (0.9% saline, i.p.) for 11 days. Systolic BP was measured by tail cuff while qPCR, immunohistochemistry and flow cytometry were used to measure ...

ECU Publications Post 2013

The Mediterranean diet has demonstrated efficacy for improving cardiovascular and cognitive health. However, a traditional Mediterranean diet delivers fewer serves of dairy and less dietary calcium than is currently recommended in Australia, which may limit long-term sustainability. The present study aims to evaluate whether a Mediterranean diet with adequate dairy and calcium can improve cardiovascular and cognitive function in an at-risk population, and thereby reduce risk of cardiovascular disease (CVD) and cognitive decline. A randomised, controlled, parallel, crossover design trial will compare a Mediterranean diet supplemented with dairy foods against a low-fat control diet. Forty participants with systolic blood pressure ...

Von Willebrand Disease, Ramon Misla David

The Kabod

Von Willebrand Disease (VWD) is a blood clotting disorder characterized by low levels of the Von Willebrand Factor (VWF) in the blood. VWF is functions to bind platelets and promote clotting of the blood when vascular injury occurs. Therefore, VWD leads to decreased or impaired clotting. There are three main types and four subtypes of VWD (type 1, 2A, 2B, 2N, 2M, and 3). Each type of VWD increases in severity. VWD is diagnosed preliminarily through a personal and family history and physical examination. Upon indications toward the possibility of a bleeding disorder, an initial hemostasis evaluation is performed followed ...
