Managing alloimmunization, delayed hemolytic transfusion reactions, and hyper-hemolysis in sickle cell disease
… the transfused RBCs, a condition known as hyper-hemolysis. Additional transfusions can aggravate these symptoms and lead to death. Clinicians’ awareness of DHTR events is poor because its clinical presentations mimic those of vaso-occlusive crisis. Furthermore, immunohematology at times detect no …

The effect of selected colonic metabolites of polyphenols on the copper-triggered Fenton reaction and hemolysis
… on the copper-triggered Fenton reaction and hemolysis Keywords: polyphenol, metabolite, copper, Fenton reaction, hemolysis, antioxidant, pro- oxidant Copper is an essential trace biogenic element that plays a pivotal role in various physiological processes within the human body. It is a …

The effects of hyperthermia and ionizing radiation on chicken erythrocytes: A possible model for terminally differentiated tissues
… of hyperthermia and radiation produced more hemolysis than either heat or radiation alone. Postirradiation heating was the only protocol that caused prompt hemolysis and it also induced the greatest amount of hemolysis. The amount of hemolysis induced by preirradiation heating was very …

Studies on the nature of red blood cell hemolysis on storage and the nature of the red blood cell membrane acetylcholinesterase
… of RBC ^ChE seemed to coincide with the onset of hemolysis. In vivo (10, 11) and in vitro (12, 13) experiments by other investigators, however, provided no evidence that AChE is essential for the maintenance of normal RBC life spanc In view of their observations it is of great interest to …

Evaluation eines Hemoresistometers
… tests. Estimation of mean complications like hemolysis and coagulation for futher/future use in-vivo are more difficult. Especially the comparability of indices of hemolysis from different kind of pumps and of different working groups is problematic. So far it is not possible to separate …

Drag reducing polymers as simple indicators of hemolytic potential in biomechanical devices
… between experimental results and actual hemolysis results. Experimental results showed that the mathematical difference between the average final and initial viscosity of HM II was greater than the difference for HM III. HM II had a difference of 0.21 cP and HM III had a difference of …

Erfassung der Hämolyse mittels optischer Reflexionsspektroskopie
The mechanical blood damage (hemolysis) is a critical fact of medical blood assisting devices. In order to minimize the physiological stress of the patients, the flow rate must be adapted in terms of hemolysis. In this dissertation a new method for a continuous detection of hemolysis is presented. …

Effects of Heat and of Ultrasound on Terminally-Differentiated Cells: The Erythrocyte as a Model System
… the terminally- differentiated erythrocyte using hemolysis as end-point. The heat-induced hemolysis of chicken and rat red blood cells (RBC's) was determined between 45 and 51.5$\sp\circ$C. Rat RBC's were more heat sensitive than chicken RBC's. Survival following split-heating was the same as …

Analysis of a membrane type blood oxygenator and a ventricle type blood pump
… analysis included oxygen transfer studies and hemolysis studies. The oxygenator was able to transfer as much as 140cc0₂/min/m² at a flow rate of 300 ml/min with flow augmentation. Inlet oxygen saturation 1vas between 25-35%. Both the oxygenator and the ventricle type blood pump caused only very …

Gut Microbiome Dysbiosis Exacerbates Malaria Severity in Ugandan Children
… Elevated blood uric acid levels during SM from hemolysis and impaired renal clearance likely increases levels of intestinal uric acid, which supports the growth of uricase producing bacteria such as Enterobacteriaceae. Furthermore, Enterobacteriaceae associated with multiple complications of SM …

Einfluss dreier verschiedener Techniken der extrakorporalen Zirkulation auf Parameter der Hämodynamik, Inflammation, Blutgerinnung und Hämolyse bei aortokoronaren Bypass-Operationen : die konventionelle Herz-Lungen-Maschine im Vergleich mit zwei miniaturisierten Bypass-Systemen
… e.g. systemic inflammatory response syndrome, hemolysis, hemodilution, coagulopathy, global hemodynamic dysfunction. These adverse effects occur due to the contact of blood with non-endothelial surfaces and air, intraoperative hypothermia, hemodilution as the result of bypass priming and …

Kenngrößenorientierte Beurteilung von Rotationsblutpumpen diagonaler Bauart mittels numerischer Strömungssimulation
… on the numerical estimation of the flow induced hemolysis for rotary blood pumps. Therefore, a new approach calculating the “accumulated” blood damage in rotary blood pumps was chosen to develop a semi-empiric model. In most published models, blood damage is locally calculated and subsequently …

Fabrication of microfluidic devices for artificial respiration
… such a way to minimize shear stress and reduce hemolysis and thrombosis inside the microchannel. It allowed alternative flow pathways in the event of single channel occlusion while minimizing the establishment of detrimental pressure gradients. The hemocompatibility analysis demonstrated that …

Homopolar bearingless slice motors with magnet-free rotors for extracorporeal life support
… challenge is to reduce blood damage, e.g., hemolysis, which is primarily caused by the stress and heat from the pump impeller's bearing surface. Another challenge is to reduce the cost of the impeller module that is disposed after each use and therefore incurs a repeated cost. This thesis …

Identify Causes of Unacceptable Turnaround Time in Sample Recalls and Develop Corrective Actions to Improve Patient Service in the Clinical Laboratory
… the top cause for test cancellation was hemolysis and worked to create a standard workflow to reduce the numbers of specimens sent to the Regional Lab that would ultimately be cancelled and result in a patient recall. Additionally, we created a standard workflow to respond to cancelled …
