The blood may also be irradiated, which destroys the DNA in the white cells and prevents graft versus host disease, which may happen if the blood donor and recipient are closely related, and is also important for immunocompromised patients. Other modifications, such as washing the RBCs to remove any remaining plasma, are much less common.
The term thrombocyte (clot cell) came into use in the early 1900s and is sometimes used as a synonym for platelet; but not generally in the scientific literature, except as a root word for other terms related to platelets (e.g. thrombocytopenia meaning low platelets).
In the context of microbiology, enucleation refers to removing the nucleus of a cell and replacing it with a different nucleus.This is used mainly in cloning but can also be used for creating hybrids of plants or animals.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: additional coagulation factors beyond factor VII (listed below) respond in a cascade to form fibrin strands, which strengthen the platelet plug. [1] Coagulation is highly conserved throughout biology
The blood donor center is the facility that collects blood components from screened blood donors, either whole blood or separate components such as plasma or platelets only via apheresis. These blood components are then transported to a central location for processing such as fractionation, testing and redistribution.
Physicians specialized in hematology are known as hematologists or haematologists. [2] Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewing blood films and bone marrow slides under the microscope, interpreting various hematological test results and blood clotting test results.
Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation , for a variety of purposes. [ 1 ]
