ABSTRACT Glomuvenous malformations, also known as glomangiomas, are tumor-like malformations or hamartomas of the glomus body. They can be sporadic or inherited as an autosomal dominant disease. Glomuvenous malformations tend to resemble hemangiomas. Clinical distinction between these entities is important due to their different therapeutic approaches. Surgical excision is the treatment of choice for isolated, ...
In this paper the output timing jitter of a solitonsource, based on the gain-switching technique of asemiconductor laser, is analysed. A laboratorial timing jittermeasurement, at the laser output, is initially performed,followed by the identification of its origins. Aftercharacterizing the laser noise and the electrical signal, usedto pulsate the laser, a numerical model is developed in orderto be used in the s...
We present the recent results regarding the application of cascades of GEMs and a MHSP in the detection and imaging of X-rays and UV-photons. The imaging system tested consisted in a micropattern gas detector based in multi-GEM or multi-GEM/MHSP electron multipliers, a 20´20 mm2 Wedge & Strip (W&S) readout electrode with 1.6 mm pitch positioned below and at close distance of a resistive electrode,...
Matrix Gla protein (MGP) is a secreted vitamin K-dependent protein (VKD) located in the extracellular matrix and capable of binding calcium through its -carboxyglutamate residues. Although identified in 1983, transcriptional and post-transcriptional mechanisms regulating its expression remain unclear.
Therapy with bone marrow-derived cells has been used in ischemic patients with reported success. The aim of this study was to determine the therapeutic efficacy of fresh and frozen human umbilical cord blood cells (hUCB) in Wistar rats submitted to permanent occlusion of the left coronary artery. Three hours after myocardial infarction, 2 x 10(7) hUCB cells or vehicle were administered by intramyocardial inject...
Os dados básicos para estimar a evapotranspiração de referência de Penman-Monteith FAO (EToPM) são: temperaturas máxima e mínima, pressão de vapor real ou atual, radiação líquida e velocidade do vento, muitas vezes indisponíveis por requererem estações meteorológicas específicas. O objetivo deste trabalho foi avaliar a adequação do método para estimar a EToPM, utilizando-se dados mínimos integrados a um Sistema...
