Brain activation of the defensive and appetitive survival systems in obsessive ...

Several studies have shown that basic emotions are responsible for a significant enhancement of early visual processes and increased activation in visual processing brain regions. It may be possible that the cognitive uncertainty and repeated behavioral checking evident in Obsessive Compulsive Disorder (OCD) is due to the existence of abnormalities in basic survival circuits, particularly those associated with ...

Innovative Developments in Virtual and Physical Prototyping

A creative solution for rapid and inexpensive model-making in product design pr...

Rapid prototyping (RP) is an approach for automatically building a physical object through solid freeform fabrication. Nowadays, RP has become a vital aspect of most product development processes, due to the significant competitive advantages it offers compared to traditional manual model making. Even in academic environments, it is important to be able to quickly create accurate physical representations of con...

Utilização de máquina fotográfica digital (multi-burst) para aulas experimentai...

Nesse trabalho foi utilizada uma máquina fotográfica digital, com a função multi-burst (fotos tiradas em sequência) para analisar o movimento de queda livre e com os dados obtidos calcular o valor da aceleração da gravidade local. Para avaliar o experimento, foi também calculado um valor teórico para aceleração da gravidade local. Comparado com o obtido experimentalmente, foi possível observar um desvio pequeno...

Using SysML in systems design

System of systems involves several secondary systems working together with its creation gathering the knowledge of several distinct disciplines and teams, each one with their own background and methods, leading to a difficult communication between them. SysML, a language originated from UML, enables that communication, without background interference, with the use of a rich notation for systems design. This pap...

Características da carcaça e da carne de bovinos sob diferentes dietas, em conf...

Avaliaram-se as características qualitativas da carcaça e da carne de 10 tourinhos, de 10 machos castrados e de 10 fêmeas da raça Canchim, terminados em confinamento e alimentados com: 1 - silagem de milho e concentrado contendo farelo de soja, milho e polpa cítrica (SM) e 2 - cana-de-açúcar e concentrado contendo farelo de soja, milho, grãos de girassol e polpa cítrica (CA). O período experimental foi de 105 d...

Pharmacological study of anti-allergic activity of Syzygium cumini (L.) Skeels

Myrtaceae is a plant family widely used in folk medicine and Syzygium and Eugenia are among the most important genera. We investigated the anti-allergic properties of an aqueous leaf extract of Syzygium cumini (L.) Skeels (SC). HPLC analysis revealed that hydrolyzable tannins and flavonoids are the major components of the extract. Oral administration of SC (25-100 mg/kg) in Swiss mice (20-25 g; N = 7/group) inh...

Differential effect of plant lectins on mast cells of different origins

Histamine release induced by plant lectins was studied with emphasis on the carbohydrate specificity, external calcium requirement, metal binding sites, and mast cell heterogeneity and on the importance of antibodies bound to the mast cell membrane to the lectin effect. Peritoneal mast cells were obtained by direct lavage of the rat peritoneal cavity and guinea pig intestine and hamster cheek pouch mast cells w...
