There is not any method to measure metatarsal protrusion in the whole metatarsal. The aim of this research is to know the normal metatarsal parabola in male and female feet. The system of measurement devised by Hardy and Clapham to evaluate the protrusion between metatarsals I and II was adapted to study the whole metatarsal parabola and applied to the five metatarsals of 169 normal feet, 72 fe...

BACKGROUND Cell migration plays an essential role in many biological processes, such as cancer metastasis, wound healing and immune response. Cell migration is mediated through protrusion and focal adhesion (FA) assembly, maturation and disassembly. Epidermal growth factor (EGF) is known to enhance migration rate in many cell types; however it is not known how FA maturation, FA dynamics and pro...

Various complications following ventriculoperitoneal (VP) shunting have been reported but transoral protrusion of peritoneal catheter is a very rare situation. This case is the first adult with a transoral VP shunt protrusion in available literature. A 47-year-old female with pseudotumor cerebri admitted after the peritoneal catheter protruded from her mouth during retching. Endoscopic examinat...

The use of multidetector computed tomography (MDCT) is an integral part of contemporary diagnostics of Graves‘ orbitopathy. The aim of this study was to assess proptosis measurement by MDCT and to compare it to the current standard, Hertel exophthalmometry. A cross-sectional study was conducted at the Clinical Centre of Serbia and included 91 patients (19 male and 72 female) with verified Grave...

Wenlin procedure is a special operation designed by us. In the early stage, it was specially used for treatment of pectus carinatum. Later, we found that also had an effect on other protrusion deformities. Barrel chest can be regarded as overall wall, so kind deformity. Because there protrusion, should play role. We this in barrel and obtained satisfactory results. Our experience shows ideal ch...

Protrusion of the leading edge of migrating epithelial cells requires precise regulation of two actin filament (F-actin) networks, the lamellipodium and the lamella. Cofilin is a downstream target of Rho GTPase signaling that promotes F-actin cycling through its F-actin-nucleating, -severing, and -depolymerizing activity. However, its function in modulating lamellipodium and lamella dynamics, a...

We develop a mathematical model that describes key details of actin dynamics in protrusion associated with cell motility. The model is based on the dendritic-nucleation hypothesis for lamellipodial protrusion in nonmuscle cells such as keratocytes. We consider a set of partial differential equations for diffusion and reactions of sequestered actin complexes, nucleation, and growth by polymeriza...

Femoroacetabular impingement (FAI) is a condition characterized by the impingement of the femur and acetabulum. In Japan, this disorder has become recognized gradually. Here we report a rare case of surgically treated FAI, associated with an osseous protrusion on the acetabulum of a 30-year-old female. Plain computed tomography (CT) and reconstructive 3D-CT images clearly demonstrated an antero...

La protrusion pyramidale périanale est une entité d'individualisation récente, assez rare, touchant presque exclusivement le sexe féminin souvent en bas âge, d'origine congénitale, fonctionnelle ou associée au lichen scléroatrophique. Dans la première forme, la lésion serait due à une faiblesse constitutionnelle de la paroi périnéale, notamment du raphé médian, ou serait secondaire à une malfor...

1 ABSTRACT The continuous casting process is a widely used technique in modern steel plants. However, it is a complicated process that is not well understood. The objective of this research is to model the porosity and macrosegregation due to shrinkage related effects and solid deformation in the continuous casting of steel. Solid phase movements due to bulging and variable roll gap are modeled...
