13. Recuperação hidrometalúrgica de metais da drenagem ácida de minas por precipitação seletiva
Acid mine drainage (AMD) is an important water pollution problem in coal production. The active treatment of AMD involves the addition of alkaline reagents to increase the pH and precipitate the dissolved metals as hydroxides. Although active treatment can provide effective remediation, it has the disadvantages of high operational costs and problems related

14. PurificaÃÃo, caracterizaÃÃo e determinaÃÃo de atividade coagulante da lectina de sementes de Moringa oleifera
Moringa oleifera is a tropical plant of great economic importance with several industrial and medicinal applications. Many parts of the plant are used and the seed extract is commonly employed for water purification to human consumption. Lectins are proteins or glycoproteins of nonimmune origin, which bind carbohydrates bioespecifically with agglutinant cell

15. Purification and partial characterization of a coagulant serine protease from the venom of the Iranian snake Agkistrodon halys
Agkistrodon halys is one of several dangerous snake species in Iran. Among the most important signs and symptoms in patients envenomated by this snake is disseminated intravascular coagulation. A thrombin-like enzyme, called AH143, was isolated from Agkistrodon halys venom by gel filtration on a Sephadex G-50 column, ion-exchange chromatography on a DEAE-Sep

16. Isolation and characterization of a serine proteinase with thrombin-like activity from the venom of the snake Bothrops asper
A serine proteinase with thrombin-like activity was isolated from the venom of the Central American pit viper Bothrops asper. Isolation was performed by a combination of affinity chromatography on aminobenzamidine-Sepharose and ion-exchange chromatography on DEAE-Sepharose. The enzyme accounts for approximately 0.13% of the venom dry weight and has a molecul

17. Atividade hemaglutinante e larvicida (Aedes aegypti) na Ãgua tratada com sementes de Moringa oleifera
Moringa oleifera seeds have been frequently used as coagulant for water treatment in Brazilian Northeast, where a high incidence of dengue fever. Lectins constitute a heterogeneous protein group capable of recognizing and reversibly binding to carbohydrates and glycoproteins. Protease inhibitors disrupt enzymatic action by formation of stable complexes with

18. MolÃculas bioativas de Moringa Oleifera: detecÃÃo, isolamento e caracterizaÃÃo
Moringa oleifera à uma planta tropical com grande importÃncia econÃmica e de usos industriais e medicinais. Diferentes partes da planta sÃo aplicadas e o extrato de sementes à comumente usado na purificaÃÃo de Ãgua para consumo humano. Ãcidos hÃmicos constituem uma significante fraÃÃo de matÃria orgÃnica natural que ocorre em rios e constituem

19. Caracterização cinética da protease trômbica presente no veneno de "Bothrops leucurus":: leucurobina.
It was obtained in this work more data about leucurobin, a snake venom thrombin-like enzyme from Bothrops leucurus, very common in Brazilian Northeast. The kinetic parameters KM, kcat, kcat/KM over p-nitroanilin chromogenic substrates was determined. The coagulant activity over citrated human plasma and purified bovine fibrinogen was evaluated. Leucurobin ha

20. CLARIFICAÇÃO DE ÁGUAS PLUVIAIS RICAS EM ÓXIDOS DE FERRO ACUMULADAS EM CAVA DE MINERAÇÃO ATRAVÉS DA UTILIZAÇÃO DE UM COAGULANTE NATURAL, A MORINGA OLEIFERA
The surface waters, which run off over the slopes of a trench of the Mina de Alegria Mariana (MG), carry solid particles of several dimensions, which settle in the bottom. These waters have high turbidity, red colour and high stability of the suspended particles, basically constituted by iron oxides (hematite e goethite). To allow the maintenance of the mini

21. Neutralization of the edema-forming, defibrinating and coagulant effects of Bothrops asper venom by extracts of plants used by healers in Colombia
We determined the neutralizing activity of 12 ethanolic extracts of plants against the edema-forming, defibrinating and coagulant effects of Bothrops asper venom in Swiss Webster mice. The material used consisted of the leaves and branches of Bixa orellana (Bixaceae), Ficus nymphaeifolia (Moraceae), Struthanthus orbicularis (Loranthaceae) and Gonzalagunia pa

22. Age-related biological activity of South American rattlesnake (Crotalus durissus terrificus) venom
An in vitro and in vivo comparative study was performed on the effects of Crotalus durissus terrificus venoms from a mother and its 15 newborns. The venoms were tested for protein content, lethality, proteolytic, myotoxic, hemorrhagic, and phospholipase A2 activity. The minimum coagulant dose in plasma and human fibrinogen, protrhombin, and Factor II activat

23. Influencia do tipo de coagulante e do aquecimento no cozimento da massa na composição, rendimento. proteolise e caracteristicas sensoriais do queijo prato. / Influence of the type of coagulante and the heating in the baking of the mass in the composition, income, proteólise and sensorial characteristics of the cheese plate.
The objective of this work was to determine the influence of the coagulant type in the composition and yield of Prato cheese manufactured with and without the curd wash (direct and indirect heating) and to evaluate the differences occurred in the sensorial characteristics during the aging period. The studied coagulants were Rhizomucor miehei protease, calf r

24. Estudos bioquimico e farmacologico da peçonha de Bothrops erythromelas
B. elythromelas is a snake found exc1usivelyin the Northeast of Brazil (from Bahia to Ceará). In this Thesis, some of the biochemical and pharmacological characteristics of this venom were examined. B. erythromelas venom possesses coagulant activity as well as proteolytic (caseinolytic), phospholipase and TAME-esterase activities. Practionation of the venom
