Abstract:

The spontaneous hemoluminescence of blood and wound discharge in 26 patients operated in artificial circulation is studied. In uncomplicated course during artificial circulation and after operation independent of the effect of applied hemodilutants the increase of hemoluminescence of blood is found. Similar changes on days 23 after intervention are revealed in wound discharge. The indices approach to the initial values on days 45 after artificial circulation. Deviations from described dynamics coincide, as a rule, with grave postoperative state of patients. On the basis of the results of inves

We advance the notion that much like artificial nanoparticles, relatively more complex biological entities with nanometric dimensions such as pathogens (viruses, bacteria, and other microorganisms) may also acquire a biomolecular corona upon entering the blood circulation of an organism.

We review published supporting data and generalize these notions from artificial nanoparticles

Abstract:

The use of cardiopulmonary bypass (CPB) technologies is often associated with ischemic and re-perfusion injury to the myocardium. The contact of patient’s blood with the surface of the extracorporeal circuit leads to platelets activation and often triggers a systemic inflammatory reaction. Nitric oxide (NO) is a signal molecule produced by the endothelium of blood vessels. Under normal circumstances, it prevents excessive activation and aggregation of platelets, thus providing an organ-protective effect. Currently, there is a considerable amount of data available about positive effects of use

Abstract:

The prevalence of obesity is increasing, and the origins of obesity and metabolic dysfunction may be traced back to fetal life. Currently, overweight pregnant women are advised to substitute sugar-sweetened beverages with diet drinks containing artificial sweeteners. Recent evidence suggests that the consumption of artificial sweeteners during pregnancy increases the risk of obesity in the child, but the mechanism is unknown. We hypothesized the transportation of artificial sweeteners across the placenta into the fetal circulation and the amniotic fluid. We included 19 pregnant women who were

Abstract:

Heart is a complex structure which acts as a blood pump in mammal’s body. It is important to have detail study for the heart structure. Modeling of heart structure gives a better understanding and figure of the heart valve’s movement as well as the fluid flow movement in the heart chamber. In this paper, the heart simulator (Heart-S) on the left ventricle for measuring the blood circulation during cardiac cycle was proposed. Throughout the experimental modeling of heart valve structure by using rhythmic fluid flow in a closed chamber, the relationship between heart valve elasticity and heart v

Abstract:

The cardiovascular system is vital for human physiology, regulating blood circulation. Cardiovascular Diseases (CVDs), including cardiac arrhythmias, can disrupt the heartbeat rhythm, impacting blood circulation. Black-box computational modeling of this system can facilitate the development of novel methods and devices to assist in diagnosing and treating CVDs. Artificial Neural Networks (ANNs) represent an effective black-box approach. Implementation involves selecting a database, separating training and test sets, and defining the model structure.

Abstract:

During veno-venous extracorporeal membrane oxygenation (V-V ECMO), blood is drained from the central venous circulation to be oxygenated and decarbonated by an artificial lung. It is then reinfused into the right heart and pulmonary circulation where further gas-exchange occurs. Each of these steps is characterized by a peculiar physiology that this manuscript analyses, with the aim of providing bedside tools for clinical care: we begin by describing the factors that affect the efficiency of blood drainage, such as patient and cannulae position, fluid status, cardiac output and ventilatory str

In recent years, endovascular aortic replacement (TEVAR) has proven itself as a treatment option for many aortic diseases with a mortality rate up to 7.5 %. According to the latest clinical recommendations, TEVAR has become the method of choice in the treatment of acute aortic dissection, showing better results compared to medical therapy and open surgery.

Abstract:

Sudden cardiac death is the number one killer in the western world. In the USA alone, CPR attempts are justified in 200,000 cases per year. Recovery of brain function requires immediate initiation and uninterrupted maintenance of artificial ventilation and circulation by basic life support (BLS) until restoration of spontaneous circulation (ROSC) is possible with advanced life support (ALS). Presently recommended standard CPR (SCPR) produces only 6–30% of normal common carotid blood flow. For this reason, a more effective method of prolonged CPR-BLS is necessary in the absence of ALS ambulance

Introduction. The need to develop effective methods of renal protection during cardiac surgical interventions is dictated by the progressive increase of acute kidney injury (CS-AKI) in children, which is associated with immaturity of renal function and damaging factors of cardiopulmonary bypass (CPB): activation of systemic inflammation response, hypothermia, hemodilution, hemolysis, transfusion of donor blood components, hypoxia/hyperoxia. CS-AKI in this population results in worsening of both early and long-term patient prognosis. However, there is no universally accepted strategy for nephro
