4. Identification and quantification of plasma heparanase isoforms in gastrointestinal carcinoma patients. / Identificação e quantificação das isoformas da heparanase em plasma de pacientes com carcinomas gatrointestinais.
Heparanase-1 (HPA1) is an endo-β-glucuronidase that degrades intradisaccharides glycosidic linkage between hexosamine and glucuronic acid into heparan sulfate chains, present on extracellular matrix and surface proteoglycans. HPA1 gene is located at 4q21.3 chromossome. Oligosaccharides generated by HPA1 are involved in cell proliferation, angiogenesis a

5. Sobre a ocorrência e a genealogia de amostras brasileiras de Coronavirus canino (CCoV) e o papel de cães como reservatórios para Rotavirus / On the occurrence and genealogy of Brazilian strains of Canine coronavirus (CCoV) and the role of dogs as reservoirs for rotavirus
Viral canine gastroenteritis is infectious transmissible diseases with importance for animal health, as those caused by Canine parvovirus and Canine coronavirus (CCoV) and public health, as in the case of rotavirus. Canine rotavirus occurs at low frequencies, both in diarrheic and health dogs, but the importance of dog as reservoirs for human rotaviruses is

6. Immiscible liquid-liquid displacement in capillary tubes: viscoelastic effects
The displacement of a fluid by liquid injection occurs in some practical applications like oil recovery in porous media and cementation of drilling wells. The dimensionless numbers that govern this problem are the capillary number, Reynolds number and viscosity ratio. An overview of selected oil recovery processes shows that hydrolyzed polyacrilamide and bio

7. Estudo da ação do inibidor de proteinase de Adenanthera pavonina sobre o desenvolvimento e atividade das proteinases intestinais de lagartas de Diatraea suchharalis (FABR., 1794) / Study of proteinase inhibitor action from Adenanthera pavonina on the development and midgut proteinase activities of the Diatraea sachharalis larvae (FABR., 1794)
Phytophatogous insects and other animals use digestive enzymes, such as amylases and proteinases to process the nutrients obtained from the plants necessary for their development. The sugarcane borer Diatraea saccharalis is the major pest of sugarcane in Brazil and other South American countries. Plants synthesize a variety of molecules, including proteinase

8. Caracterização parcial e atividades farmacológicas do extrato rico em polissacarídeos sulfatados da angiosperma marinha Halodule wrightii
Sulfated polysaccharides (PS) are biomolecules with a great biotechnological potential. There are few data about PS from high plants. In addition, pharmacological activities of PS from plants have not been carrying out. The aim of this work was extract PS from the angiosperm Halodule wrightii and study their anticoagulant and antioxidant activities. Histolog

9. Efeito de um inibidor de tripsina de sementes de Plathymenia foliolosa sobre o desenvolvimento e atividade enzimatica de Anagasta kuehniella / Effect of a trypsin inhibitor from Plathymenia foliolosa seeds on Anagasta kuehniella development and enzymatic activity
Proteinase inhibitors (PIs) are widely distributed in animals, microorganisms, and plants. Plant PIs are generally small proteins that have mainly been described as occurring in storage tissues, such as tubers and seeds, but they have also been found in the aerial parts of plants, in the leaves, flowers and roots. The possible roles suggested for seed protei

10. Influência do puerpério e da retenção dos anexos fetais no proteinograma de fêmeas bovinas da raça Holandesa, criadas no Estado de São Paulo / Influence of puerperium and retained fetal membranes on the proteinogram of Holstein cows raised in the State of São Paulo
The aim of this study was to evaluate the influence of the puerperal period and retained fetal membranes on the proteinogram of Holstein cows. Two hundred ninety one blood samples were collected from cows through ninety days postpartum. In order to study the physiologic puerperium, blood samples from one hundred two clinically animals, divided in 9 experimen

11. Análise de polimorfismos do gene da fibrilina-1 em indivíduos portadores de hérnia inguinal através do seqüenciamento de DNA / Polymorphisms analysis of the fibrillin-1 gene in individuals with inguinal hernia by DNA sequencing
The inguinal hernia is a multifactorial disease that emerge from the Fruchaud orifice, closed only by the transversalis fascia. Lately it has been showed that disorders on the connective tissue elements, as the collagen and elastic fibers, are related to the inguinal hernia genesis. Previous studies have showed structural and quantitative changes of the elas

12. Efeito de um inibidor de proteinase serinica sobre o desenvolvimento e atividade enzimatica de Heliothis virescens (Lepidopter: Noctuidae) / Effect of a trypsin inhibitor on the development and enzymatic activity of Heliothis virescens (Lepidoptera: Noctuidae)
Proteinase inhibitor proteins (PIs) are one of the defensive chemicals produced by plants against pests and pathogens. PIs are polypeptides that are able to bind to insect midgut proteolytic enzymes, rendering them inactive by competitive inhibition. This process leads to a limitation of essential amino acids in protein synthesis, and thus, to reduction in g
