Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood, in order to replicate inside a patient and produce additional normal blood cells.
This process is also used for exchange transfusion in severe malaria, or in sickle cell patients with specific indications such as acute chest syndrome or stroke. Thrombocytapheresis – removal of platelets in people with symptoms from extreme elevations in platelet count such as those with essential thrombocythemia or polycythemia vera .
An arenavirus is a bi- or trisegmented ambisense RNA virus that is a member of the family Arenaviridae. [1] [2] These viruses infect rodents and occasionally humans.A class of novel, highly divergent arenaviruses, properly known as reptarenaviruses, have also been discovered which infect snakes to produce inclusion body disease, mostly in boa constrictors.
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone.
However, in people with conditions where the cells die early (such as sickle cell disease), parvovirus infection can lead to severe anemia. [15] [16] More frequently, parvovirus B19 is associated with aplastic crisis, which involves only red blood cells (despite the name). Aplastic anemia involves all cell lines.
Micrographs of grades of skin graft-versus-host disease: Ranging from grade I GvHR (with minimal vacuolization in the epidermis) to grade II GvHR (with vacuolization and dyskeratotic bodies) to grade III GvHR (with sub epidermal cleft formation) and finally to grade IV GvHR (with separation of the dermis from the epidermis) [2]
Thalassemias are inherited blood disorders that result in abnormal hemoglobin. [7] Symptoms depend on the type of thalassemia and can vary from none to severe. [1] Often there is mild to severe anemia (low red blood cells or hemoglobin) as thalassemia can affect the production of red blood cells and also affect how long the red blood cells live. [1]
Vietnamese (tiếng Việt) is an Austroasiatic language spoken primarily in Vietnam where it is the national and official language.Vietnamese is spoken natively by around 85 million people, [1] several times as many as the rest of the Austroasiatic family combined. [5]
