Comparison Between Conventional And Applied Vertebral Heart Score (Vhs) Methods To Evaluate Heart Size In Healthy Thai Domestic Shorthair Cats, Jetsada Rungpupradit, Somchin Sutthigran

The Thai Journal of Veterinary Medicine

Thoracic radiography is the most common first modality for heart size evaluation and confirming cardiogenic pulmonary edema in cats with suspected heart diseases. The Vertebral Heart Score (VHS) was established as an objective methodfor diagnosing cardiomegaly via thoracic radiography. However, the conventional VHS method is inappropriate for cats with abnormal thoracic vertebrae.Therefore, the applied VHSmethod, which uses the lateral view axis sum divided with the length of each thoracic vertebra (T4, T5 and T6) was created to minimize the limitation of VHS in these cases. This study compared the conventional and the applied VHS methods in healthy Thai domestic shorthair …

Medicine In Spirituality, Ashesh Soni, Krunal Patel

be Still

Modern day medicine places a major emphasis on appreciating spirituality. A patient’s cultural and religious beliefs are integral when practicing medicine in order to provide the most humanistic care possible to patients. This photograph comes to show the exact opposite, medicine in spirituality. Medicine is an integral part of a medical professional's life and it serves as a major defining characteristic of an individual. Though viewed as objective and subjective, medicine and spirituality are all one.

Lack Of Osteopontin Induces Systolic And Diastolic Dysfunction In The Heart Following Myocardial Ischemia/Reperfusion Injury, Caytlin James

Undergraduate Honors Theses

Ischemic heart disease is a leading cause of death worldwide. Osteopontin (OPN), a cell-secreted extracellular matrix protein, is suggested to play a cardioprotective role in mouse models of ischemic heart disease. The objective of this study was to examine the role of OPN in modulation of systolic and diastolic functional parameters of the heart following mouse ischemia/reperfusion (I/R) injury. For this, wild-type (WT) and OPN-knockout (KO) mice aged approximately 4 months were subjected to cardiac ischemia for 45 minutes by the ligation of the left anterior descending coronary artery (LAD) followed by reperfusion of LAD by snipping the ligature. Heart …

Critical Care Ultrasonography And Its Application For Covid-19, Xi Liu, Md, Yang Hai, Md, Bin Ma, Md, Weelic Chong, Md, Ji-Bin Liu, Md

Department of Radiology Faculty Papers

Ultrasound has developed as an invaluable tool in diagnosis and proper management in the intensive care unit (ICU). Application of critical care ultrasonography is quite distinct from the routine comprehensive diagnostic ultrasound exam, because the urgent setting mandates a goal-directed approach. Performing accurate and efficient critical care ultrasound requires ultrasound providers to first understand the pathophysiology of the disease and related imaging findings, and then follow the protocols to perform a focused ultrasound exam. In the ongoing coronavirus disease 2019 (COVID-19) pandemic, ultrasound plays an essential role in diagnosing and monitoring critically ill COVID-19 patients in the ICU. Our review …

Potential Role Of The Large Protein Titin In The Development Of Heart Failure, Mary M. Prickett

Senior Theses

I will be exploring the impact of the large protein Titin on heart failure with a preserved ejection fraction (HFpEF). It was hypothesized that myocardial Titin plays a significant role in the progression of HFpEF through isoform, N2BA and N2B, changes. It was hypothesized that an increase in the quantity of N2B Titin, less compliant, and a decrease in N2BA Titin, more compliant, will be observed as HF progresses, contributing to an increase in passive stiffness involved in heart contraction. I will cover a detailed report on the role of Titin in HFpEF and propose research methods to explore further.

Pitfalls In Quantitative Myocardial Pet Perfusion I: Myocardial Partial Volume Correction, K Lance Gould, Linh Bui, Danai Kitkungvan, Tinsu Pan, Amanda E Roby, Tung T Nguyen, Nils P Johnson

Journal Articles

BACKGROUND: PET quantitative myocardial perfusion requires correction for partial volume loss due to one-dimensional LV wall thickness smaller than scanner resolution.

METHODS: We aimed to assess accuracy of risk stratification for death, MI, or revascularization after PET using partial volume corrections derived from two-dimensional ACR and three-dimensional NEMA phantoms for 3987 diagnostic rest-stress perfusion PETs and 187 MACE events. NEMA, ACR, and Tree phantoms were imaged with Rb-82 or F-18 for size-dependent partial volume loss. Perfusion and Coronary Flow Capacity were recalculated using different ACR- and NEMA-derived partial volume corrections compared by Kolmogorov-Smirnov statistics to standard perfusion metrics with established …

Enhancement Of The Syncardia Total Artificial Heart For Pediatric Use, Margaret Clark, Madison Marks

Williams Honors College, Honors Research Projects

Pediatric patients with disorders and diseases of the heart have limited options with regards to implantable devices. Many of these implants are ventricular assist devices, which is not always suitable for a patient. Total artificial hearts (TAHs) have supported many adult patients until transplantation, and we believe that they could do the same for pediatric patients. SynCardia has the only Food and Drug Administration (FDA) approved TAH devices. Since SynCardia is the only company with FDA approved TAHs, we decided to modify the design of the SynCardia TAH for use in pediatric patients without compromising the function of the current …

Left Ventricular Strains During Late Filling In A Preclinical Model, Saar Peles

Honors Undergraduate Theses

Understanding the mechanisms governing left ventricular function and dysfunction is critical to analyze cardiovascular disorders and gaining insights into possible therapies. Left ventricular function can be evaluated using Magnetic Resonance Imaging (MRI). Cardiac displacements and corresponding strains are then computed from the imaging data. In measuring and assessing the left ventricle’s motion, images are taken either in the short axis (top-down) or long axis (side) views. In this project, we will use DENSE MRI data, which measures the displacements of individual tissue voxels during the cardiac cycle.

After extracting the myocardial tissue by segmenting the MR images, strains are computed …

Journal Articles

This paper collates the pathological findings from initial published autopsy reports on 23 patients with coronavirus disease 2019 (COVID-19) from 5 centers in the United States of America, including 3 cases from Houston, Texas. Findings confirm that COVID-19 is a systemic disease with major involvement of the lungs and heart. Acute COVID-19 pneumonia has features of a distinctive acute interstitial pneumonia with a diffuse alveolar damage component, coupled with microvascular involvement with intra- and extravascular fibrin deposition and intravascular trapping of neutrophils, and, frequently, with formation of microthombi in arterioles. Major pulmonary thromboemboli with pulmonary infarcts and/or hemorrhage occurred in …

Light And Scanning Electron Microscopic Examination Of The Saanen Goat Heart, Sedef Selvi̇ler Si̇zer, Yonca Beti̇l Kabak, Murat Kabak

Turkish Journal of Veterinary & Animal Sciences

It is important to know the morphological structure of the heart, which is a vital organ of the body, in detail. For this reason, we aimed to examine the morphological structure of the Saanen goat heart using light and scanning electron microscopy (SEM). A total of thirteen Saanen goat hearts were used in the study. To demonstrate the histological structure of the heart, samples taken from 9 hearts were fixed in 10% formaldehyde solution and blocked in paraffin after routine histological procedures. Histological staining was performed on the sections taken from the blocks. Four hearts were fixed in a 2.5% …
