Blood coagulation is a critical hemostatic process that must be properly regulated to maintain a delicate balance between bleeding and clotting. Disorders of blood coagulation can expose patients to the risk of either bleeding disorders or thrombotic diseases. Coagulation diagnostics using whole blood is very promising for assessing the complexity of the coagulation system and for global measur...

Introduction Coagulation alterations after a subarachnoid hemorrhage (aSAH) secondary to aneurysm rupture are frequent and clinically relevant. They may impact negatively in the outcome. The diagnosis of coagulopathy with the standard tests is limited as only the initial part of coagulation process is being assessed. In contrast, thromboelastography provides the whole blood clot information, al...

For decades warfarin has been the oral anticoagulant of choice. However, in recent years there has been a significant shift towards the use of NOACs. Unlike most other medications, such as warfarin [1] and anti-hyperglycaemic agents [2], the protocol for perioperative cessation of NOACs remains unclear. The aim of this review is to summarise a growing body of evidence surrounding the perioperat...

Abstract Background Assuring safety and survival of blood in vitro depends on anti-coagulation substances, blood bag characteristics, storage conditions, and transport of blood. Besides, careful selection and screening of donors as well as blood tests can minimize the transmission risk of blood-transmissible pathogens and optimize blood health. The aim of this study was to assay the level of ...

Introduction Cold plasma is a self-sterilized, painless, and non-contact method in surgeries. These properties allow it to be applied to the living tissues and heat-sensitive parts. The aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...

Low haematocrit values are generally well tolerated in terms of oxygen transport but a low haematocrit might interfere with blood coagulation. We thus sampled 60 ml of blood in 30 healthy volunteers. The blood was centrifuged for 30 min at 2000 g and separated into plasma, which contained the platelet fraction, and packed red blood cells. The blood was subsequently reconstituted by combining th...

BACKGROUND Laboratory tests can be an important source of blood loss in hospitals, especially for newborns and patients in intensive care. The aim of this study was to quantify blood loss for laboratory diagnostic tests in a large number of patients in a teaching hospital. METHODS We estimated blood loss by multiplying the number and volumes of sampling tubes collected from 2654 adult inpatie...

Between 2007 and 2013, the Council of Australian Governments (COAG) introduced major national policy reforms to improve quality in early childhood education and care (ECEC) (Brennan and Adamson, 2014). By analysing policy documents underpinning the COAG reforms for early childhood, this article contends these reforms have been so far-reaching that, conceivably, they could have a lasting impact ...

Coagulation technology has been used since 1970 in northern Chile for removing arsenic from drinking-water. This experience suggests that coagulation is an effective technology for the removal of arsenic. It is currently possible to reduce arsenic from 400 microg/L to 10 microg/L at a rate of 500 L/sec, assuming pH, oxidizing and coagulation agents are strictly controlled. The Chilean experienc...

The Smoluchowski equations of coagulation are solved analytically in two cases involving a finite cut-off of the system: the constant kernel set to zero for any j > N on the one hand, and the general three-particle case on the other. Both are seen to exhibit rather unusual large-time behaviour. The first model can be used to account for large particles precipitating out of a system and its beha...
