Myocardial Perfusion Imaging After Severe COVID-19 Infection Demonstrates Regional Ischemia Rather Than Global Blood Flow Reduction

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: Acute myocardial damage is common in severe COVID-19. Post-mortem studies have implicated microvascular thrombosis, with cardiovascular magnetic resonance (CMR) demonstrating a high prevalence of myocardial infarction and myocarditis-like ...

Impact of Ig-Therasorb (R) immunoapheresis on stability of xenogeneic ex vivo porcine liver perfusion - Value of aminotransferases and flow rates for the assessment of metabolic graft viability [PDF]

open access: yes, 2000
Due to growing shortage of donor organs, the concept of extracorporeal pig liver perfusion in the treatment of acute liver failure has been rediscovered.

Mild hyperthermia enhances sensitivity of gastric cancer cells to chemotherapy through reactive oxygen species–induced autophagic death

open access: yesTumor Biology, 2017
Mild hyperthermia enhances anti-cancer effects of chemotherapy, but the precise biochemical mechanisms involved are not clear. This study was carried out to investigate whether mild hyperthermia sensitizes gastric cancer cells to chemotherapy through ...

Monitoring Microcirculatory Blood Flow during Cardiopulmonary Bypass in Paediatric Cardiac Surgery Patients as a Predictor for Anaerobic Metabolism [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Introduction: Improving tissue oxygenation is one of most important tasks in management of low cardiac output. Central venous oxygen saturation (ScvO2 ) and lactate are established criteria for monitoring the adequacy of tissue oxygenation.

Automated Detection of Regions of Interest for Brain Perfusion MR Images [PDF]

open access: yes, 2018
Images with abnormal brain anatomy produce problems for automatic segmentation techniques, and as a result poor ROI detection affects both quantitative measurements and visual assessment of perfusion data.

High pressure excursion in a radial design oxygenator

open access: yesThe Journal of ExtraCorporeal Technology
Oxygenator high-pressure (HPE) is a phenomenon that can occur during cardiopulmonary bypass (CPB) in which the oxygenator inlet pressure increases rapidly, thereby limiting flow. Most perfusionists globally do not use inlet oxygenator pressure monitoring

Usefulness of a visual aid in achieving optimal positioning for spinal anesthesia: a randomized trial

open access: yesBMC Anesthesiology, 2018
Background Optimal patient positioning is perceived as an essential factor to increase the success of performing neuraxial blockade. The primary objective of this study was to evaluate the benefit of using a visual image in addition to verbal ...

Infrared Thermography in Wound Care, Surgery, and Sports Medicine: A Review

open access: yesFrontiers in Physiology, 2022
For many years, the role of thermometry was limited to systemic (core body temperature) measurements (e.g., pulmonary catheter) or its approximation using skin/mucosa (e.g., axillary, oral, or rectal) temperature measurements.

Subnormothermic Perfusion in the Isolated Rat Liver Preserves the Antioxidant Glutathione and Enhances the Function of the Ubiquitin Proteasome System. [PDF]

open access: yes, 2016
The reduction of oxidative stress is suggested to be one of the main mechanisms to explain the benefits of subnormothermic perfusion against ischemic liver damage. In this study we investigated the early cellular mechanisms induced in isolated rat livers
