El gen de FXI tiene una longitud de 23 kb, posee 15 exones, y se encuentra en el brazo largo del cromosoma 4 4q Vistas Leer Editar Ver historial.

The extracts could act preventing the conversion of prothrombin to thrombin, also they could fia stopping the transformation of fibrinogen to convert it to fibrin o even in the polymerization of this last molecule. Highly sulfated dermatan sulfates from ascidians. Thrombosis is a health problem that affects many people in the world.

Biochemical and Biophysical Research Communications 2: We considered an algal extract with anticoagulant activity similar to heparin when this impede the clot formation during 10 minutes or more. An International Journal in Haemostasis and Thrombosis 16 4: Caulerpa paspaloides Chlorophyta fue activa solamente en el tiempo de trombina. Forty nine species were tested, 14 from Chlorophyta, 8 from Phaeophyta and 27 belonging to Rhodophyta.

Consultado el 7 de abril de Journal of Clinical Pathology 6: The extracts were prepared mixing 10 g fresh weight of algal material and 10 ml of phosphate buffer PB 0. Pharmacological activities of marine algae. Anticoagulant activity in extracts of British marine algae. Comparative Biochemistry and Physiology B: Inhibition of thrombin by sulfated vis isolated from green algae.

Factor de coagulación XI

Biochimica et Biophysica Acta Recently, a group of scientists had stand out the potentiality of some proteins and proteoglycans capable of interfere with blood clotting cascade, particularly from Codium Matsubara et al. Supporting the use of this method is the evidence that the results of Deacon iva al. En humanos, el factor XI se encuentra codificado por el gen F Chemical structure of extrinsecx Rhamnan sulfate from Monostroma nitidum.

The research effort has been focused on one genus, forgotten the basic detection of different algae as a potential source of alternative anticoagulant molecules. Finally, sample collected in April of change the anticoagulant activity been active only in the thrombin time test.

Seasonal variations in the production of antifungal substances by some dictyotales brown algae from the French Mediterranean coast. Occurrence of heparin in the invertebrate Styela plicata Tunicata is restricted to cell layers facing the outside environment. The Hague, The Netherlands. Blood coagulation and haemostasis.

However we consider more research has to be done, focused to this topic, in order to probe this hypothesis.

We can concluded that these species can be considered as potentially alternative source of anticoagulant molecules. Cladistics of the Bryopsidales: Antimicrobial and cytotoxic terpenoids from tropical green algae of the family Udoteaceae.

Se concluye que estas especies pueden ser consideradas como una fuente alternativa de nuevos anticoagulantes. We also detected a variation in the anticoagulant potency, a change in the anticoagulant activity related with the intrinsic or extrinsic pathways of coagulation or even dw disappearance of the anticoagulant activity in both test of Caulerpa cupressoidesC. The sites of collection of Veracruz state were: Cytogenetics and Cell Genetics 52 Heparin, a sulphated glycosaminoglycan wide used in oral anticoagulant therapy, was used as reference in both proofs.

Anticoagulant, fibrinolytic and antiaggregant activity of carrageenans and alginic acid. Our results showed four species with similar activity susceptible of further research for isolation and characterizations of active substances.

It has been done research in anticoagulant activity of polysaccharides and glycosaminoglycans of diverse sources such as: Current views on blood coagulation and haemostatic mechanism. This is the first report of anticoagulant activity in Anadyomene stellataLobophora variegata and Liagora farinosa. It has been reported also that brown algae have a potent anticoagulant activity in fucoidans Chevolot et al.

In Campeche state we colleted phycological material in: Journal of Phycology Journal of Molecular Biology 2:
