Hemostatic serine proteinases-thrombin, Factor VIIa, Factor Xa, play the central role in blood coagulation and thrombosis. Activation of coagulation and generation of active proteinases is initiated by tissue factor (TF) that is expressed by cells of the innate immune system and endothelial cells after tissue damage and cell activation induced by trauma, infection, hypoxia and other cell injury...

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...

BACKGROUND The aims of the present study were to confirm the consumption coagulopathy of disseminated intravascular coagulation with the fibrinolytic phenotype at an early phase of trauma and to test the hypothesis that thrombin-activatable fibrinolysis inhibitor, neutrophil elastase, and plasmin contribute to the increased fibrinolysis of this type of disseminated intravascular coagulation. Fu...

Objective Argon plasma coagulation (APC) and helium plasma coagulation (HPC) are electrosurgical techniques that provide noncontact monopolar electrothermal haemostasis. Although these techniques have been widely used clinically during the last three decades, their in vivo effects on liver tissue remain unclear. Methods We investigated the effects of different power levels (10-100 W) of APC and...

Reports on Noonan syndrome (NS) have documented multiple types of coagulation defects and bleeding diathesis, and a wide range of clinical presentations. Early studies suggested that a large proportion of NS patients have coagulation defects, whereas more recent reports indicate low rates of coagulopathy. The aim of this study was to evaluate phenotypic characteristics, PTPN11 gene mutations, a...

Erbium laser wavelengths circa 3,000 nm are highly energy efficient and spatially accmate for photothermal ablation; their photothermal coagulation depths are significantly shorter than gingival blood vessel diameters. Carbon dimdde (CO~ laser wavelengths circa 10,000 nm are exh·emely effective and spatially accmate photothermal ablation tools with exemplary coagulation ability as a result of a...

BACKGROUND Vascular targeting of malignant tumors has become a clinically validated new treatment approach with clear patient benefit. However clinical studies have also revealed that some types of vascular targeting agents (VTAs) are prone to coagulation system side effects. It is therefore essential to predetermine coagulation parameters in preclinical studies. As of to date, this has rarely ...

Substantial progress has been made in understanding the contribution of alterations in coagulation and fibrinolysis to the pathogenesis of acute lung injury (ALI). Findings from mouse, rat, baboon, and human studies indicate that alterations in coagulation and fibrinolysis may be of major pathogenetic importance in ALI and other inflammatory conditions in the lung including pneumonia, sepsis, a...

We propose a blood coagulation testing method based on the measurement of the flow velocity near the bottom surface of a microchannel by using a surface plasmon resonance (SPR)-based microfluidic device. We were able to distinguish the coagulation ability in different human plasma samples by observing the flow velocity change caused by coagulation that occurred at an interface between a plasma ...
