Resumen
Abstract Disseminated intravascular coagulation (DIC) is a pathological coagulopathy associated with infection that increases mortality. In DIC, excessive thrombin generation causes symptoms from formation of microthrombi to multiorgan failure; bleeding risks can also be a concern because of clotting factor consumption. Different clinical events lead to DIC, including sepsis, trauma, and shock. Treatments for thrombotic episodes or bleeding presentation in DIC oppose each other, thus creating therapeutic dilemmas in management. The objective of this study was to develop fibrin-specific core-sh

Resumen
Abstract Trousseau syndrome is classically defined as migratory, heparin-sensitive but warfarin-resistant microthrombi in patients with occult, mucinous adenocarcinomas. Injecting carcinoma mucins into mice generates platelet-rich microthrombi dependent on P- and L-selectin but not thrombin. Heparin prevents mucin binding to P- and L-selectin and mucin-induced microthrombi. This model of Trousseau syndrome explains resistance to warfarin, which inhibits fluid-phase coagulation but not selectins. Here we found that carcinoma mucins do not generate microthrombi in mice lacking P-selectin glycopr

Resumen
COVID-19 is a global concern that emerged and became a pandemic at March 2020. It is related to dysregulation of immune system causing excessive immune response known as cytokine storm. Other than that there is hypercoagulation that could progress to thrombosis and embolism in various vital organs. Pulmonary embolism is one of the dire consequences of hypercoagulation. CTPA and V/Q scan are the gold standards in pulmonary embolism diagnosis. However in developing countries like Indonesia these facilities are often absent. Thus a simple blood test like Ddimer could aid the detection of pulmonar

We present the postmortem findings of an unexpected death due to acute myocardial infarction (AMI) with microthrombi and thrombosis in other vessels after the first dose of coronavirus disease 2019 (COVID-19) vaccination (ChAdOx1 nCov-19). The deceased was a 69-year-old woman who complained of nonspecific symptoms shortly after vaccination and was found dead on the sixth day. Postmortem examination revealed AMI and complications (left ventricular rupture, hemopericardium) with microthrombi in small cardiac vessels, which are similar to the characteristic findings of myocardial injury caused by

Resumen
Background and Purpose: Delayed neurological deficits are a devastating consequence of subarachnoid hemorrhage (SAH), which affects about 30% of surviving patients. Although a very serious concern, delayed deficits are understudied in experimental SAH models; it is not known whether rodents recapitulate the delayed clinical decline seen in SAH patients. We hypothesized that mice with SAH develop delayed functional deficits and that microthrombi and infarction correlate with delayed decline. Methods: Adult C57BL/6J mice of both sexes were subjected to endovascular perforation to induce SAH. Mic

Resumen
INTRODUCTION: Microthrombosis (platelet aggregation) has been suggested as a major factor contributing to delayed neurological deterioration in patients after subarachnoid hemorrhage (SAH). However, experimental studies on the role of microthrombi in delayed deficits after SAH have not been investigated in depth. Similarly, the only clinically existing antiplatelet therapy is nimodipine, with other therapies being invasive. METHODS: SAH was induced in adult male and female C57BL/6 mice via endovascular perforation. Mice were randomly assigned into sham (n=6/sex) or SAH groups (n=22-24/sex). A

Resumen
De nouvelles études suggèrent que l'accident vasculaire cérébral ischémique est fréquemment associé à la formation de microthrombi dans la microcirculation corticale. Ces microthrombi sont associés à une augmentation de la taille de la lésion, à un déclin cognitif et à la démence. Il est difficile de prendre en charge ces microthrombi car les méthodes d'imagerie actuelles ne permettent pas de les détecter. Pour y remédier, un nouvel agent théranostique a été développé, les IO@PDA@tPA, combinant des microparticules d'oxyde de fer (IO) enrobées de polydopamine (PDA) et conjuguées avec l’activate

Resumen
The coronavirus disease 2019 (COVID-19) primarily affects the respiratory system, commonly manifesting as pneumonia. The clinical presentation of COVID-19 is challenging to distinguish from community-acquired pneumonia due to other etiologies and respiratory exacerbations of pre-existing chronic respiratory diseases. Fortunately, the majority of patients have an asymptomatic or mild illness. However, some patients may develop profound hypoxemia secondary to diffuse alveolar damage and occlusion of alveolar capillaries by microthrombi.

Resumen
Introduction: Thrombotic thrombocytopenic purpura (TTP) is a hematological disease resulting from the ADAMTS 13 plasmatic protein deficit. It can be congenital or sporadic, and is usually autoimmune. Pathological platelet adhesion occurs, leading to microthrombi in capillary and arterial circulation, microangiopathic anemia and ischemia. The clinical picture includes thrombocytopenia, renal dysfunction, fluctuating neurological symptoms, microangiopathic hemolytic anemia, and fever.

Fibrinolytic activity is reportedly increased during cardiopulmonary bypass( CPB ), and this increase has been considered to be related to the bleeding complications in open heart surgery. The purpose of this study was to clarify the nature of the fibrinolytic activity duringCPB. Twenty patients with valve replacement or aortocoronary bypass surgery were examined. The following parameters were determined: fibrinogen, plasminogen, fibrinopeptide A( FPA ), fibrinopeptide B β 15-42 ( FPB β15-42 ), and tissue-type plasminogen activator ( t-PA ).

Resumen
Abstract The influence of convective flow on the transport of prothrombin, thrombin, antithrombin, ADP and thromboxane in the vicinity of a mural microthrombus has been analysed applying computer simulation. The basis of the study is a suitable reaction, emission and transport model. The reaction kinetics and the mass transport are modelled mathematically with a coupled system of convection-diffusion equations. The description of the flow field near the microthrombus uses the three-dimensional Navier-Stokes equations. The numerical approach applies the finite element method.

Resumen
A new agent developed in our laboratory, 4-cyano-5,5-bis(4-methoxyphenyl)-4-pentenoic acid (E-5510), suppressed various human platelet functions in vitro. The compound also showed quite potent ex vivo anti-platelet effects in many experimentalanimals. It is well known that anti-platelet effects are not always parallel to anti-thrombotic effects. Thus, in order to predict the efficacy of E-5510 in thrombotic disorders, the anti-thrombotic effects were examined in 3 different animal models of thrombosis.(1) Anti-thrombotic effect in an extracorporeal shunt model Two hrs after oral administration
