Abdominal Aortic Aneurysm Endovascular Repair: Profiling Postimplantation Morphometry and Hemodynamics with Image-Based Computational Fluid Dynamics
(2018)Endovascular aneurysm repair (EVAR) has disseminated rapidly as an alternative to open surgical repair for the treatment of abdominal aortic aneurysms (AAAs), because of its reduced invasiveness, low mortality, and morbidity ... -
Assessment of Dynamic Changes in Stressed Volume and Venous Return during Hyperdynamic Septic Shock
(2022)The present work investigated the dynamic changes in stressed volume (Vs) and other determinants of venous return using a porcine model of hyperdynamic septic shock. Septicemia was induced in 10 anesthetized swine, and ... -
Associations between cardiorespiratory fitness, fatness, hemodynamic characteristics, and sedentary behaviour in primary school-aged children
(2022)Background: Low cardiorespiratory fitness (CRF) is associated with the development of cardiovascular diseases during childhood, adolescence and older ages. The purpose of the study was to investigate associations between ... -
Baseline Values and Kinetics of IL-6, Procalcitonin, and TNF- α in Landrace-Large White Swine Anesthetized with Propofol-Based Total Intravenous Anesthesia
(2021)The baseline levels of various inflammatory mediators and their changes during anesthesia in swine are not known. The aim of this animal study was to measure the baseline values and kinetics of interleukin-6, procalcitonin, ... -
Blood flow and diameter effect in the navigation process of magnetic nanocarriers inside the carotid artery
(2022)Background and objective: Serious side effects are occurred during the cancer therapy. Magnetic driving of nanoparticles is a novel method for the elimination of these effects by supplying with anticancer drug or increase ... -
Blood flow velocity comparison in the eye capillaries and postcapillary venules between normal pregnant and non-pregnant women
(2020)Background: There is no consensus on how much and at what diameters the blood flow velocity changes in the female microcirculation during normal pregnancy. Methods: A non-contact, digital slit-lamp biomicroscopy system was ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Comparison of physiological performance of four adaptive servo ventilation devices in patients with complex sleep apnea
(2019)[No abstract available] -
A comparison of propofol, thiopental or ketamine as induction agents in goats
(2005)Objective: To compare propofol, thiopental and ketamine as induction agents before halothane anaesthesia in goats. Study design: Prospective, randomized cross-over study. Animals: Seven healthy adult female goats with mean ... -
A computational fluid dynamics modelling of maternal-fetal heat exchange and blood flow in the umbilical cord
(2020)Human fetal thermoregulation, maternal-fetal heat exchange, and the role of the umbilical cord in these processes are not well understood. Ethical and technical limitations have restricted current knowledge to animal ... -
COVID-19 hemodynamic and thrombotic effect on the eye microcirculation after hospitalization: A quantitative case-control study
(2022)BACKGROUND OBJECTIVE: To quantify the hemodynamic and thrombotic effect of COVID-19 on the eye microcirculation of patients with thromboprophylaxis, shortly after hospital discharge. METHODS: This case-control study included ... -
A critical appraisal of the pharmacological management of stable angina
(2021)The once dominant plaque-centric model of the pathophysiology and management of coronary artery disease (CAD) has long been questioned by a bulk of experimental and clinical evidence suggesting, among others, that coronary ... -
Determinants of venous return in steady-state physiology and asphyxia-induced circulatory shock and arrest: an experimental study
(2022)Background: Mean circulatory filling pressure (Pmcf) provides information on stressed volume and is crucial for maintaining venous return. This study investigated the Pmcf and other determinants of venous return in dysrhythmic ... -
Development and Testing of a Novel Anaesthesia Induction/Ventilation Protocol for Patients With Cardiogenic Shock Complicating Acute Myocardial Infarction
(2018)Background: Cardiogenic shock is a life-threatening condition and patients might require rapid sequence induction (RSI) and mechanical ventilation. In this study, we evaluated a new RSI/mechanical ventilation protocol in ... -
Diagnosis and treatment of acute isolated proximal internal carotid artery occlusions: a narrative review
(2022)The clinical manifestations of proximal (extracranial) internal carotid artery occlusions (pICAOs) may range from asymptomatic to acute, large, and devastating ischemic strokes. The etiology and pathophysiology of the ... -
The effect of carotid revascularization on the ophthalmic artery flow: Systematic review and meta-analysis
(2021)Introduction: High-grade internal carotid stenosis results in impaired flow dynamics in the ocular circulation that may lead to a rare clinical entity; ophthalmic ischemic syndrome (OIS). The aim of this study was to ... -
Effect of Glyceryl Trinitrate on Hemodynamics in Acute Stroke: Data from the ENOS Trial
(2019)Background and Purpose - Increased blood pressure (BP), heart rate, and their derivatives (variability, pulse pressure, rate-pressure product) are associated with poor clinical outcome in acute stroke. We assessed the ... -
Effect of macroscale formation of intraluminal thrombus on blood flow in abdominal aortic aneurysms
(2016)A mathematical approach of blood flow within an abdominal aortic aneurysm (AAA) with intraluminal thrombus (ILT) is presented. The macroscale formation of ILT is modeled as a growing porous medium with variable porosity ... -
The effect of plasma osmolality and baroreceptor loading status on postexercise heat loss responses
(2016)We examined the separate and combined effects of plasma osmolality and baroreceptor loading status on postexercise heat loss responses. Nine young males completed a 45-min treadmill exercise protocol at 58 ± 2% V O2 peak, ... -
