background: the present study investigated the functional maturity of oligodendrocyte derived from rat bone marrow stromal cells (bmsc). methods: the bmsc were isolated from female sprague-dawley rats and evaluated for different markers, such as fibronectin, cd106, cd90, oct-4 and cd45. transdifferentiation of olc from bmsc was obtained by exposing the bmsc to dmso and 1 µm all-trans-retinoic a...

platelet activating factor (paf) is a novel signaling phospholipids that in addition to platelet activation has many biological properties. the acrosome reaction, as an essential step in mammalian fertilization, can occur in response to several agents such as paf. therefore, the present study aimed to assess the effect of paf on the motility and acrosome reaction of ram spermatozoa. semen was c...

platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of cerastes persicus fieldi and echis carinatus were investigated. the partial fractionation was performed on a sephadex g-100 column. two fractions separated from cerastes persicus fieldi showed anti platelet aggregation activity on adp (200 µm)-induced platelet aggregation (ca 80% inhibi...

Intraplatelet phospho-VASP analysis is a commonly used approach for monitoring of anti-platelet therapy; however, testing of intraplatelet phospho-VASP expression needs a high level of experience and proficiency. The ability to recognize how the pre-analytical variations can change the results would be helpful for the interpretation of data from intraplatelet P-VASP analysis. The aim of this st...

Platelets are known to contribute to vascular pathologies, however, their role in inflammatory disorders of the central nervous system (CNS), such as multiple sclerosis (MS) and its mouse model, experimental autoimmune encephalomyelitis (EAE), is thus far poorly defined. Although there is emerging evidence that platelets might accumulate in the CNS parenchyma along with an increased activation ...

objective: some of the adverse effects of aspirin including peptic ulcers, gastrointestinal bleeding and aspirin resistance compelled researchers to find a suitable alternative with fewer adverse effects. in this clinical trial, we aimed to find the effective antiplatelet dose of garlic. materials and methods: this randomized controlled clinical trial (rct) was conducted on 62 healthy volunteer...

background and aims: despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. blood-borne pathogen transmission has been a concern since the earliest days of transfusion. the blood product of platelet (plt) concentrates is still faced with the risk of bacterial and viral contaminations. pathogen inactivation technologies offer a proac...

amegakaryocytic thrombocytopenia (amt) is a rare cause of acquired thrombocytopenia. the pathogenesis and treatment of amt is not clearly known. here we demonstrate a 50-year-old man presented with the clinical manifestations of severe thrombocytopenia (7000 platelets/µl) with a marked decrease to absent of megakaryocytes in the bone marrow. the patient did not respond to intravenous immunoglob...
