Résumé Les tumeurs tubulo-papillaires représentent 10% des carcinomes à cellules rénales. Elles sont plus fréquentes chez l’homme que chez la femme (sex ratio: 8/1). L’âge moyen se situe dans la sixième décade. Sur le plan anatomopathologique, on distingue deux types: le 1 correspondant à une prolifération de cellules basophiles et le type 2 qui correspond à une prolifération de cellules éosino...

Individualisé en 1992, le lymphome de manteau est un lymphome B rare, développé au dépend des cellules du manteau folliculaire des centres germinatifs des ganglions, touchant le sujet âgé, souvent disséminé avec splénomégalie, envahissement médullaire et tropisme particulier pour les muqueuses digestives. Les cellules lymphomateuses expriment des marqueurs pan B, elles sont CD5 positives et CD2...

Background Hair is an ectodermal structure, and its formation is regulated by master genes important in embryology. Hair shaft consists of three major regions: the medulla, cortex and cuticle. Hair shaft abnormality will divide structural hair abnormalities into two broad categories - those associated with increased hair fragility and those not associated with increased hair fragility. We condu...

background: one of the pollutant components that can be observed in many industrial wastewaters is formaldehyde. the biological treatment of the wastewater contaminated by formaldehyde is very difficult due to its antibacterial property. however the removal of formaldehyde using adsorption process is feasible but it may be expensive. the main purpose of this study is to examine the adsorption o...

We identify a subalgebra Ĥ + n of the extended affine Hecke algebra Ĥn of type A. The subalgebra Ĥ + n is a u-analogue of the monoid algebra of Sn n Z≥0 and inherits a canonical basis from that of Ĥn. We show that its left cells are naturally labeled by tableaux filled with positive integer entries having distinct residues mod n, which we term positive affine tableaux (PAT). We then exhibit a c...
