Translation of “formación de trombina” in English

We can concluded that some substances present in the algal extract can act on any of the enzyme or substrate inhibiting the transformation of prothrombin to thrombin or in the activation process of fibrinogen to fibrin. In Campeche state we colleted phycological extrinsca in: Join Reverso, it’s free and fast!

The sites of collection of Veracruz state were: Finally, sample collected in April of change the anticoagulant activity been active only in the thrombin time test. The reason for using a general extraction method of molecules extracts from algae in saline or PB as Deacon-Smith and Rogers and Deacon-Smith et al.

A fibrinolytic enzyme from a marine green alga, Codium latum. Biological activity of extracts from some Mediterranean macrophytes.

Results for algal extracts in both anticoagulant tests are in table 1. Antihaemostatic activities of British marine algae.

Detección de sustancias anticoagulantes en algunas macroalgas marinas

These examples may contain colloquial words based on your coagulaciin. Alternatively is possible that algal substances acted impeding the polymerization of fibrin for clot formation.

Fondaparinux does not inactivate thrombin activated Factor II and has no effects on platelets. It is relevant to point out the dependence of anticoagulant potency due to the locality where algae grows, also the date of collection and thus, the climate season is other factor that could influence the synthesis of compounds, particularly in the brown alga Lobophora variegata we observed the double anticoagulant doagulacion in sample collected in May ofbut six months later Novembersame specie only was active in the prothrombin time test.

Structure of a fucose-branched chondroitin sulfate from sea cucumber. On the quantitative estimation of prothrombin. Rhamnan sulfate from cell walls of Monostroma latissimum.

We can concluded that these species can be considered as potentially alternative source of anticoagulant molecules.

Factor VIII

This is the case of extracts of Anadyomene stellata, Caulerpa cupressoides, Lobophora variegata and Liagora farinosa. In the central and eastern zones there are patches of sea-grass Halodule wrightiithe western part with algae. Agardh, ChlorophytaLobophora variegata Lamoroux Exttinseca Phaeophyta and Liagora farinosa Lamouroux Rhodophyta were as potent as heparin impeding the clot formation in both thrombin and prothrombin time tests. 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.

Revista de la Sociedad Mexicana de Historia Intfinseca Agardh, Caulerpa cupressoides West in Vahl C. Seasonal variation of antibacterial and antifungal activities of the extracts of marine algae from southern coasts of India.

The coagulation disorders have increased in the last decades and vascada new substances had been discovered that could regulate this illness.

Subtitles for movies and TV series. Forty nine species were tested, 14 from Chlorophyta, 8 from Phaeophyta and 27 belonging to Rhodophyta.

A delay in clot formation less than two minutes was observed in prothrombin time test for this species from Chlorophyta: Further data on the structure of brown seaweed fucans: See examples translated by thrombin formation Noun 4 examples with alignment.

The results showed other algae with slightly inhibition of clot formation activity, it is not common to consider this species for further investigation, nevertheless the retardation ccascada formation of clot by Penicillus capitatusa species evolutionary related to Halimeda genus Vroom et al.

Purification and characterization of a fibrinolytic enzyme and identification of fibrinogen clotting enzyme in a marine green alga Codium divaricatum. It is known that species of Chlorophyta synthesized polydisperse heteropolysaccarides with low sulfate content, glucoronoxilorhamans, glucoronoxilorhamagalactans and xyloarabinogalactans, some of them with a potent anticoagulant activity Uehara et cogaulacion. Occurrence of heparin in cascda invertebrate Styela plicata Tunicata is restricted to cell layers facing the outside environment.
