3. The effect of smoking on myeloid-related protein-8 and myeloid-related protein-14
Abstract The aim of this study was to determine the myeloid-related protein-8 and myeloid-related protein-14 levels in the gingival crevicular fluid of smoker patients with generalized aggressive periodontitis (SAgP), smoker patients with chronic periodontitis (SCP), smoker patients with gingivitis (SG-smoker control), non-smoker patients with generalized ag

4. Unfractionated heparin and mechanical thromboprophylaxis in hip arthroplasty
OBJECTIVE: To evaluate the efficacy and safety of unfractionated heparin associated with mechanical prophylaxis as a method for preventing venous thromboembolism in hip arthroplasty. METHOD: We retrospectively reviewed the records of 181 hip arthroplasties out of 216 consecutive cases performed over a period of 39 months in our hospital. We excluded 35 case

5. Effect of a cordless retraction paste on titanium surface: a topographic, chemical and biocompatibility evaluation
Good exposure of the preparation margins and haemostasis in the sulcular gingiva are necessary for accurate impressions to produce precise restorations. The use of cordless retraction paste material in implant dentistry is a relatively novel application. However, few studies have been conducted on the use of retraction pastes and their possible interaction w

6. Avaliação das atividades farmacológicas de uma serinoprotease, isolada a partir do veneno total de Brothrops barnetti / Evaluation of pharmacological activities of a serine protease, isolated from the venom total Brothrops barnetti
Os venenos de serpentes contêm uma variedade de proteínas que são estudadas no mundo pela importância biológica e farmacológica. Dentro de sua complexa composição, o veneno apresenta enzimas proteases, como as metaloproteases e serinoproteases que estão envolvidas em distúrbios hemostáticos e coagulantes, interferindo na agregação plaquetária.

7. Thrombocytopenia in malaria: who cares?
Despite not being a criterion for severe malaria, thrombocytopenia is one of the most common complications of both Plasmodium vivax and Plasmodium falciparum malaria. In a systematic review of the literature, platelet counts under 150,000/mm³ ranged from 24-94% in patients with acute malaria and this frequency was not different between the two major species

8. Pharmacological action of tick saliva upon haemostasis and the neutralization ability of sera from repeatedly infested hosts
Ticks are blood-feeding arthropods widely distributed in the world and vectors of several diseases. As haematophagy demands evasion strategies and repeatedly infested hosts develop protective immune responses, we investigated the mechanisms of the Rhipicephalus (Boophilus) microplus saliva anti-haemostatic activity and the possible relationship between the a

9. Purificação e caracterização da antitrombina do plasma da serpente Bothrops jararaca (Wied, 1824) (Ophidia: Viperidae, Crotalinae) / Purification and characterization of Bothrops jararaca, antithrombin (Wied, 1824) (Ophidia: Viperidae, Crotalinae)
The aim of the present work was to characterize the seed development of Araucaria angustifolia through proteomics in order to understand the physiological and biochemical changes during this process. For that, initially, three different protein extraction methods were evaluated. The extraction based on protein solubilization in 7 M urea, 2 M thiourea, 1% dit

10. Efeitos do veneno de Crotalus durissus terrificus, da crotoxina e de suas subunidades fosfolipase A2 e crotapotina em monocamadas de células endoteliais em cultura. / Effects of the venom of Crotalus durissus terrificus from crotoxina and its subunits and crotapotina phospholipase A2 in monolayers of endothelial cells in culture.
Crotalus durissus terrificus snake venom (CdtV) and their components induces systemic effects, which interfere with blood vessel system. Endothelial cells (EC) are central elements for haemostasis, regulating blood vessel-wall permeability, blood fluidity and adhesion properties of circulating leukocytes. However, there is no available data on the effects of

12. Marcadores de coagulação intravascular disseminada em pacientes graves internados em unidade de terapia intensiva.
Disseminated intravascular coagulation (DIC) is a syndrome caused by systemic activation of clotting factors and it is frequently associated with several diseases such as sepsis, trauma, shock, cancer, and immune and vascular disorders. Sepsis is the main clinical condition associated to DIC. In some cases, the clinical outcome is very fast and severe, and a
