Performance and reference intervals of thrombin generation test: results from the Brazilian longitudinal study of adult health (ELSA-Brasil). A cross-sectional study

Säo Paulo med. j; 140 (3), 2022
ABSTRACT BACKGROUND: The thrombin generation test (TGT) has shown promise for investigation of hemorrhagic and thrombotic diseases. However, despite its potential, it still needs standardization. Moreover, few studies have established reference values for TGT parameters. In Brazil, these values have not...

Coagulación intravascular diseminada

Med. UIS; 33 (2), 2020
Resumen La coagulación intravascular diseminada es un estado alterado de la coagulación secundario a cuadros inflamatorios locales o sistémicos. Se caracteriza por un aumento de la coagulación y una inadecuada fibrinólisis endógena que da como resultado la formación de fibrina intravascular, tromb...

Thrombin generation and thromboelastometry tests in dogs with chronic kidney disease

Pesqui. vet. bras; 40 (2), 2020
Patients with chronic kidney disease (CKD) have paradoxical hemostatic potential because they have bleeding episodes but are also prone to thrombosis. Few studies have evaluated blood viscoelastic properties in dogs with kidney disease; on the other hand, hypercoagulability has been observed in these pat...

Eficácia e segurança de anticoagulantes orais diretos comparados à anticoagulação tradicional com heparina e varfarina para tratamento de tromboembolismo pulmonar e trombose venosa profunda
Effectiveness and safety of direct oral anticoagulants compared to traditional anticoagulation with heparin and varfarine to treat pulmonary thromboembolism and deep venous thrombosis

Tecnologia: Inibidores Diretos do Fator Xa (IDFXa) – Rivaroxabana, Apixabana, Edoxabana – e Inibidores Diretos da Trombina (IDT) – Dabigatrana – todos são anticoagulantes orais diretos (DOAC). Indicação: tratamento e prevenção de fenômenos tromboembólicos. Pergunta: Para tratamento de trom...

Standardization and evaluation of the performance of the thrombin generation test under hypo- and hypercoagulability conditions

ABSTRACT Background: In order to standardize a thrombin generation() protocol, we analyzed the analytical variables and sensitivity of this test to hypo/hypercoagulability states. Methods: The effect of the tissue factor concentration and the intra- and interassay precision were analyzed. To evaluate t...

Hemorragia posparto: nuevas evidencias

Cienc. Serv. Salud Nutr; 10 (1), 2019
Introducción: la hemorragia posparto (HPP) es toda pérdida sanguínea mayor de 500 ml luego de un parto vaginal o mayor de 1000 mililitros luego de una cesárea, o cualquier pérdida sanguínea luego del parto que provoque inestabilidad hemodinámica, independiente del tipo de parto. Puede provocar sig...

Functional and biological insights of rCollinein-1, a recombinant serine protease from Crotalus durissus collilineatus

The prevalent class of snake venom serine proteases (SVSP) in Viperidae venoms is the thrombin-like enzymes, which, similarly to human thrombin, convert fibrinogen into insoluble fibrin monomers. However, thrombin-like serine proteases differ from thrombin by being unable to activate factor XIII, thus le...

Unique heterologous fibrin biopolymer with hemostatic, adhesive, sealant, scaffold and drug delivery properties: a systematic review

Fibrin biopolymers, previously referred as "fibrin glue" or "fibrin sealants", are natural biomaterials with diverse applications on health. They have hemostatic, adhesive, sealant, scaffold and drug delivery properties and have become widely used in medical and dental procedures. Historically, these bio...

The effect of hirudin on antagonisting thrombin induced apoptosis of human microvascular endothelial cells

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To investigate whether hirudin exerts its antithrombin action to decrease the ratio of Human Microvascular Endothelial Cells (HMVECs) apoptosis. Methods: Human microvascular endothelial cells (HMVECs) cultured in the third and fifth generations were used. HMVECs were divided into nor...

Efeito da ativação do receptor ativado por protease do tipo 1 (PAR1) sobre as atividades osteogênica e cementogênica de células mesenquimais do ligamento periodontal

O receptor ativado por protease do tipo 1 (PAR1) foi o primeiro membro clonado da família de receptores acoplados à proteína G. Sua ativação tem sido associada ao reparo tecidual e cicatrização óssea. O objetivo do presente estudo foi avaliar o efeito da ativação do PAR1 nas atividades osteogê...
