1. Severe coagulopathy and transient hypertension following a Rhabdophis subminiatus bite: a case report
Abstract: Because the majority of colubrid species are considered harmless to human beings, colubrid snakebites are rarely reported. However, the venom of Rhabdophis, which is part of the Colubridae family, is procoagulant and leads to severe coagulopathy. Here, we present a case of disseminated intravascular coagulation with enhanced fibrinolysis following

2. Early postoperative changes in hematological, erythrocyte aggregation and blood coagulation parameters after unilateral implantation of polytetrafluoroethylene vascular graft in the femoral artery of beagle dogs
PURPOSE: The failure of small-caliber vascular grafts still means a serious problem. Concerning the early postoperative complications we aimed to investigate the hemostaseological and hemorheological aspects of this issue in a canine model.METHODS: In the Control group only anesthesia was induced. In the Grafted group under general anesthesia a 3.5-cm segmen

3. Disposição de lodo adensado de ETA em ETE com tratamento primário quimicamente assistido / Thickened water treatment sludge disposal in a wastewater treatment presenting a chemically enhanced primary treatment
Treatment systems, even for water potabilization or to reduce the amount of pollutants in wastewater, include physical, chemical and biological processes, and waste generation are inherent to water or sewage treatment plants. Solid waste generated in water treatment plants have inorganic characteristic, being removed from raw water by chemical and physical p

4. Evaluation of blood compatibility of plasma deposited heparin-like films and SF6 plasma treated surfaces
In devices used in open-heart surgery and dialysis, blood must be continuously processed using extracorporeal circuits composed of peristaltic pumps and active components such as specific filters and oxygenators. Several procedures have been employed to avoid blood coagulation induced by contact with the artificial surfaces of such devices. Often heparin, a

5. Microcystis aeruginosa and microcystins removal by dissolved air flotation bench scale study using aluminum sulfate and ferric chloride as coagulants. / Remoção de Microcystis aeruginosa e microsistinas por flotação por ar dissolvido : estudo em escala de bancada utilizando sulfato de alumínio e cloreto férrico como coagulantes
A ocorrência de florações de cianobactérias é preocupante e tem se tornado mais freqüente em mananciais de abastecimento brasileiros. Espécies de cianobactérias tóxicas podem liberar toxinas para a água, oferecendo risco potencial para o homem e animais que tenham contato ou consumam essa água, podendo até levar à morte. Existem alguns estudos q

6. Estabilização de latex polimericos por sorção de solventes organicos
The colloidal stability with regard to NaCI addition of homopolymer (PS-M and PS-LEV) polystyrene latexes and copolymer (P(SBMA), PS/PBMA and PBMA/PS) poly[styrene-co- butylmethacrylate)] latexes was modified by particle swelling with toluene and chloroform vapor, at 25°C. The latexes were obtained by aqueous emulsion polymerization. K2S2O4 and Na2S204 were

7. Disseminated intravascular coagulation and head injury.
Blood coagulation tests were performed on admission to the hospital and on consecutive days after severe and moderate head injury in 34 patients. Platelet counts and fibrinogen were normal at admission and raised thereafter. The partial thromboplastin time was shortened at admission and lengthened in the following days. Fibrinolytic activity was enhanced at

8. Acute coronary thrombosis in a patient with diabetes and severe hyperglycemia
The pathophysiological processes responsible for acute coronary events in diabetic patients, in addition to the conventional factors associated with plaque rupture, include an enhanced prothrombotic state. This enhanced prothrombotic state results from multiple abnormalities of the coagulation system including platelet activation, impaired fibrinolysis and i

9. Science review: Role of coagulation protease cascades in sepsis
Cellular signaling by proteases of the blood coagulation cascade through members of the protease-activated receptor (PAR) family can profoundly impact on the inflammatory balance in sepsis. The coagulation initiation reaction on tissue factor expressing cells signals through PAR1 and PAR2, leading to enhanced inflammation. The anticoagulant protein C pathway

10. Lipopolysaccharide-binding proteins of Limulus amebocyte lysate.
Limulus amebocyte lysate, obtained from horseshoe crab (Limulus polyphemus) blood cells, contains a coagulation system which is activated by bacterial lipopolysaccharide (LPS). A chromatographic fraction of Limulus lysate, containing the endotoxin-sensitive factor(s) which initiates the coagulation cascade, was studied. We utilized a photoreactive, cleavable

11. Mechanistic coupling of protease signaling and initiation of coagulation by tissue factor
The crucial role of cell signaling in hemostasis is clearly established by the action of the downstream coagulation protease thrombin that cleaves platelet-expressed G-protein-coupled protease activated receptors (PARs). Certain PARs are cleaved by the upstream coagulation proteases factor Xa (Xa) and the tissue factor (TF)–factor VIIa (VIIa) complex, but

12. Fibrinolysis and the bleeding tendency in patients with hepatosplenic schistosomiasis.
Fifty seven patients with schistosomiasis of the liver and spleen in both the compensated and decompensated states and 15 non-bilharzial subjects were studied. Fibrinogen, plasminogen, fibrinogen/fibrin degradation products, alpha 2-macroglobulin, antithrombin III and Cl-activator concentrations were evaluated in an attempt to assess abnormalities at various
