In this chapter we develop the Hamiltonian formulation of the eikonal equation and then relate it to the specific case of Blum’s grassfire flow, which gives the level sets of the Euclidean distance function to the boundary. This view provides an explicit association between medial loci and the singularities of this flow. In order to detect these singularities we consider the average outward flu...

Local production of growth factors may play a major role in vascular repair after injury. We examined the regulation of insulin-like growth factor-I (IGF-I) and its specific membrane receptor in balloon-denuded rat aorta. Aortic IGF-I mRNA and radioimmunoassayable IGF-I content increased severalfold after balloon denudation with a peak at 7 d after injury. This coincided with a reciprocal 25% d...

Objetivo: O presente estudo teve como principal intento desenvolver um Modelo Animal que pudesse acomodar experimentos de avaliação para implantes cortico-esponjosos nas áreas da Ortopedia, Odontologia e Neurologia. Metodologia: Na face antero medial do terço proximal Tíbia Suínos temos área cortico-esponjosa basicamente sub cutânea. Tal região se apresentou ideal esse objetivo. Resultados disc...

Astroglial cells derived from lateral and medial midbrain sectors differ in their abilities to support neuritic growth of midbrain neurons in cocultures. These different properties of the two types of cells may be related to the composition of their extracellular matrix. We have studied the synthesis and secretion of sulfated glycosaminoglycans (GAGs) by the two cell types under control conditi...

In this study and the accompanying article (Folgueira et al., 2004a), the fluorescent carbocyanine dye 1,1'-dioctadecyl 3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) was used in fixed tissue to comprehensively analyze the connections of the different regions of the telencephalic lobes and the preoptic region of the rainbow trout. Here, we analyze the connections of the dorsal area (D;...

conclusion lumbar medial branch nerve block under ultrasound guidance was associated with high rates of treatment success and excellent treatment outcomes for facet joint pain. it is also feasible and administers no radiation. thus, ultrasound-guided procedures can be used instead of conventional methods. results the success rate was 98% (87/89 blocks), which was due to our use of ultrasound gu...

History/Symptoms-Clinical exam features-Gait parameters-Radiographic features-Surgical technique-Evidence I. PATHOANATOMY-CLINICAL FEATURES: This is primarily a stance phase problem a. EQUINUS CONTRACTURE at the ankle because of a gastro-soleus contracture. b. Initial contact: mid foot or forefoot c. Collapse of the medial arch: i. Talus is in equinus, talo-navicular joint is subluxed ii. Os Ca...
