objective: hla-g is a nonclassical major histocompatibility complex antigen and is expressed as seven isoforms, including four membrane bound (hla-g1 to –g4) and three soluble (hla-g5 to –g7) forms. the pattern of selective expression of hla-g transcripts in tissues shows the existence of a tight transcriptional control on the gene expression. it has been revealed that cytokines including inter...

Cutaneous reactions associated with interferons (IFNs) treatment are either localized or generalized. The most common presentation of localized reactions at IFNs injection site is usually an erythematous patch or plaque. Local leukocytoclastic vasculitis presenting with cutaneous necrosis is extremely rare. We report a 19-year-old man with hepatitis B who had local leukocytoclastic vasculitis i...

Mikobakteri enfeksiyonlarına karşı Mendelyan yatkınlık, zayıf virülan mikobakteri suşları ve Salmonella gibi çeşitli hücre içi patojenlere duyarlılık ile karakterize bir primer immün yetmezlik hastalığıdır. Hastalar genellikle Bacille Calmette-Guerin aşısı sonrası gelişen lokal veya yaygın infeksiyonları, tekrarlayan moniliazis salmonella infeksiyonları kliniklere başvururlar. Hastalığın patoge...

The GAMA pattern language provides patterns for supporting dynamic teams with computer technology. In this document, a small subset of the GAMA language is presented that deals with spontaneous group formation based on common interests.

Agent-based models tend to be more and more complex. In order to cope with this increase of complexity, powerful modeling and simulation tools are required. These last years have seen the development of several platforms dedicated to the development of agent-based models. While some of them are still limited to the development of simple models, others allow to develop rich and complex models. A...

Este trabalho estudou os efeitos da radiação gama como indutora da imobilização de fases estacionárias líquidas de polidimetilsilicones usadas para separações cromatográficas em colunas recheadas. Testes de extração em solventes mostram que doses moderadas de radiação gama (80-140 kGy) produzem imobilização (90%) da maioria dos polidimetilsilicones testados em suportes do tipo Chromosorb, apesa...

A standard genetic algorithm for sorting unsigned genomes by translocations is improved in two different manners: 1. a memetic algorithm (GAMA ) is provided, which embeds a new stage of local search, based on the concept of mutation applied in only one gene; 2. an oppositionbased learning (GAOBL ) mechanism is provided, which explores the concept of internal opposition applied to a chromosome. ...
