<p class="abstract">Polymorphous low-grade adenocarcinoma (PLGA) is an infrequent type of malignant epithelial tumor that occurs almost exclusively in minor salivary glands. It commonly presents women between the sixth and eighth decade life, usually as asymptomatic mass long evolution slow growth oral cavity but can erode infiltrate adjacent bone. We present 2 case reports review literat...
BACKGROUND The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. MATERIALS AND METHODS Fifty thre...
Hydrogenated polymorphous Silicon allows to fabricate TFTs with very interesting characteristics including better threshold voltage stability than a-Si TFTs, lower leakage current than μc-Si:H TFTs and excellent uniformity. Investigation of threshold voltage shift mechanisms of pm-Si:H TFTs has shown a specific semiconductor material degradation with different activation energies compared to a-...
