BACKGROUND

ACT is commonly used for heparin anticoagulation monitoring during procedures including cardiopulmonary bypass surgery, coronary angioplasty, and interventional radiology. To prevent thrombosis, moderate to high levels of heparin anticoagulation are required. The Hemochron Signature Elite (HSE, Accriva Diagnostics, formerly ITC, San Diego, CA) was implemented at TJUH as a replacement for the older model Hemochron Response (Accriva/ITC Model HRS.110, San Diego, CA). Operating room (OR) perfusionists reported irreproducible high results using HSE that could not be explained clinically. In consideration of use of i-STAT analyzers (Abbott Point of Care, Princeton, NJ) as an alternative to HSE, we ...

Background: Growth factor, cytokine and chemokine-induced activation of PI3K enzymes constitutes the start of a complex signalling cascade, which ultimately mediates cellular activities such as proliferation, differentiation, chemotaxis, survival, trafficking, and glucose homeostasis. The PI3K enzyme family is divided into 3 classes; class I (subdivided into IA and IB), class II (PI3K-C2α, PI3K-C2β and PI3K-C2γ) and class III PI3K. Expression of these enzymes in human tissue has not been clearly defined.

Methods: In this study, we analysed the immunohistochemical topographical expression profile of class IA (anti-p85 adaptor) and class II PI3K (PI3K-C2α and PI3K-C2β) enzymes in 104 formalin-fixed, paraffin embedded ...

This article presents a 44-year-old female with progressive dyspnea, orthopnea, paroxysmal nocturnal dyspnea, and pleuritic chest pain. Examination revealed elevated jugular venous distention, lower extremity edema, and bibasilar crackles on lung auscultation, while the electrocardiogram (EKG) exhibited left bundle branch block. Two-dimensional echocardiography (2D-Echo) showed a dilated left ventricle (LV) with ejection fraction (EF) of 25% and severe diffuse hypokinesia. Cardiac magnetic resonance ...


Mechanisms Regulating Stem Cell Phenotype In Infantile Hemangioma, Niamh Richmond 2016 The University of Western Ontario

Mechanisms Regulating Stem Cell Phenotype In Infantile Hemangioma, Niamh Richmond

Electronic Thesis and Dissertation Repository

Infantile hemangiomas (IHs) are benign vascular neoplasms characterized by the differentiation of multipotential stem cells (hemSCs) into endothelial cells during the early proliferative phase, and later into adipocytes during spontaneous involution. Transforming growth factor-β (TGFβ) has been shown to be significantly elevated upon IH involution and this coincides with repression of a developmentally-regulated transcription factor T-box 2 (TBX2). These findings implicate both TGFβ and TBX2 in mediating hemSC differentiation during IH evolution. The aim of my study is to understand the role of TGFβ and TBX2 in hemSC differentiation. I performed immunofluorescence staining to localize TBX2 protein in sectioned IH ...

Malignant Hyperthermia, Aaron Roth

Master of Science in Nursing (MSN) Student Scholarship

Malignant hyperthermia is a rare disease trait and can take place in a variety of settings. If not treated in a timely manner, the consequences will be dire. It is recommended that nurses and other healthcare personnel be properly educated on MH crises. By detecting the signs and symptoms associated with the disease, providers can efficiently remedy the crisis and save patient lives (Seifert, 2014). Since the discovery of dantrolene in 1975 and the advancement of genetics regarding MH, death rates dropped from about 80% to about 5% (Schneiderbanger et al., 2014). Today there is a MH group called the ...


Complex Regional Pain Syndrome, Maria A. Hendrix 2016 Otterbein University

Complex Regional Pain Syndrome, Maria A. Hendrix

Master of Science in Nursing (MSN) Student Scholarship

Complex regional pain syndrome (CRPS) is a chronic and often disabling condition that is seen in many patients seeking pain management. The condition leaves patients in excruciating pain that is disproportionate to the inciting injury. In addition, patients with this pain disorder experience abnormal sensations such as cold and heat allodynia, hyperalgesia, edema, abnormal sudomotor activity and trophic changes (D. Lee et al., 2015). CRPS disproportionally affects four times as many women as men (Alexander, Peterlin, Perreault, Grothusen, & Schwartzman, 2012). There are two types of CRPS: type 1, often referred to as reflex sympathetic dystrophy (RSD), is not evident of ...


Airway Smooth Muscle Pathology In Pompe Disease, Lang Xiong, Allison M. Keeler, Donghai Lui, Kaitlyn Desrochers, Ronghua Zhuge, Mai K. Elmallah 2016 University of Massachusetts Medical School

Airway Smooth Muscle Pathology In Pompe Disease, Lang Xiong, Allison M. Keeler, Donghai Lui, Kaitlyn Desrochers, Ronghua Zhuge, Mai K. Elmallah

UMass Center for Clinical and Translational Science Research Retreat

Pompe disease is a rare autosomal recessive disease which results from a deficiency of acid α-glucosidase (GAA) - an enzyme that degrades lysosomal glycogen. Patients with Pompe disease develop intra-lysosomal accumulation of glycogen in multiple tissues including skeletal muscle, CNS and smooth muscle.

Pulmonary dysfunction is a hallmark of Pompe disease and has classically been attributed to muscle weakness and CNS neuropathology. However, the potential role of respiratory smooth muscles in the respiratory pathology is unknown. Therefore we postulated that GAA deficiency results in airway smooth muscle glycogen accumulation that leads to airway smooth muscle dysfunction.

Using the Pompe mouse model ...

Fair Weight Loss After Gastric Rebanding For Slippage, Ahmed Dalmar, Maharaj Singh, Sara K. Roloff, Thomas Y. Chua

Maharaj Singh

Background: Laparoscopic adjustable gastric banding (LAGB) is one of the most common bariatric surgery procedures performed in the United States. LAGB results in safe and satisfactory weight loss, but it is often complicated with slippage, a complication requiring rebanding (reoperation). There is a paucity of studies and no uniform consensus regarding weight loss after rebanding.

Purpose: This study assessed the effect of rebanding for slippage after LAGB on weight loss up to five years.

Methods: This is a historical cohort study of 865 patients who underwent LAGB from 2001 to 2011. Rebanding was performed in 103 (11.9%) patients. Primary ...

Introduction:

  • Control of the mitochondrial ATP production by SR-derived Ca2+ signals includes local, nanodomain Ca2+ transfer from ryanodine receptors (RyR2) to the mitochondrial matrix (excitation-bioenergetics coupling).
  • Ca2+ crosses the inner mitochondrial membrane (IMM) via the mtCU, a low-affinity Ca2+-activated Ca2+ channel complex.
  • The surface area of cardiac IMM is extensively enhanced by cristae folding; however, mitoplast patch clamp studies showed mtCU current density the lowest amongst a range of tissues (Fieni 2012. Nat Commun).

Department of Pathology, Anatomy and Cell Biology Faculty Papers

Zinc deficiency (ZD) increases the risk of esophageal squamous cell carcinoma (ESCC), and marginal ZD is prevalent in humans. In rats, marked-ZD (3 mg Zn/kg diet) induces a proliferative esophagus with a 5-microRNA signature (miR-31, -223, -21, -146b, -146a) and promotes ESCC. Here we report that moderate and mild-ZD (6 and 12 mg Zn/kg diet) also induced esophageal hyperplasia, albeit less pronounced than induced by marked-ZD, with a 2-microRNA signature (miR-31, -146a). On exposure to an environmental carcinogen, ~16% of moderate/mild-ZD rats developed ESCC, a cancer incidence significantly greater than for Zn-sufficient rats (0%) (P ≤ 0.05 ...

Pathology, Anatomy and Cell Biology Posters

Despite numerous methods available to identify potential mRNA targets for miRNAs, prognostic relationship of these molecules in diseases like cancers where deregulation of gene expression is a major pathogenic factor, has not yet been emphasized. We performed in-silico identification of prognostically inversely correlated miRNA - mRNA pairs (PIC’s) in multiple cancers using expression data from The Cancer Genome Atlas. Partners in a PIC show inverse correlation of expression and opposite hazard implication. Using a three step approach, we identified a total of 1,253,443 PIC’s from 23 cancer types, several of which have previously been shown to have ...
