F11 is a glycosyl phosphatidylinositol-anchored axonal surface glycoprotein belonging to a neural subgroup of the immunoglobulin superfamily. In this report, we demonstrate that the F11 protein displays three distinguishable activities: binding to the cell recognition molecule Ng-CAM, interaction with the extracellular matrix glycoprotein restrictin (RN),(More)
F11 and Nr-CAM/Bravo are two axon-associated glycoproteins belonging to different subgroups of the immunoglobulin superfamily. In this report we have investigated the interaction of both proteins using neurite outgrowth and binding assays. Antibody blocking experiments demonstrate that neurite extension of tectal cells on immobilized F11 is mediated by(More)
Tenascin-R (TN-R) is an extracellular matrix protein associated with the surface of neurons and glial cells. Immunohistological studies reveal that TN-R shows a restricted expression pattern in the developing nervous system. TN-R is the smallest member of the tenascin family and is composed of four structural motifs: a cysteine-rich segment at the(More)
The aim of this study was to compare the first and second peaks of the vertical ground reaction force (VGRF) and kinematics at initial contact (IC) and final stance (FS) during walking in one of two directions (forward×backward) and two environments (on land×underwater). Twenty-two adults (24.6±2.6 years) walking forward (FW) and backward (BW) on a 7.5m(More)

Para análise dos dados utilizou-se a estatística descritiva e inferencial (p < .05). Na comparação entre as categorias, não houve diferença para o tempo de reação visual (TRV), enquanto os profissionais apresentaram tempos de reação auditiva (TRA) significativamente menores do que os amadores. Quanto às posições em campo, os goleiros apresentaram valores de(More)
This study aimed to analyse the kinematic, kinetic and electromyographic characteristics of four front crawl flip turn technique variants. The variants distinguished from each other by differences in body position (i.e., dorsal, lateral, ventral) during rolling, wall support, pushing and gliding phases. Seventeen highly trained swimmers (17.9 ± 3.2 years(More)
