Specificity of CD8 T-Cell Responses Following Vaccination with Conserved Regions of HIV-1 in Nairobi, Kenya.

Sub-Saharan Africa carries the biggest burden of the human immunodeficiency virus type 1 (HIV-1)/AIDS epidemic and is in an urgent need of an effective vaccine. CD8 T cells are an important component of the host immune response to HIV-1 and may need to be harnessed if a vaccine is to be effective. CD8 T cells recognize human leukocyte antigen (HLA)-associated viral epitopes and the HLA alleles vary significantly among different ethnic groups.

Correlation between faecal calprotectin and magnetic resonance imaging (MRI) in the evaluation of inflammatory pattern in Crohn's disease.

Background: Calprotectin, a major cytosolic protein of neutrophils, is increased in inflammatory bowel disease (IBD) and may be considered a suitable marker of intestinal inflammation. Abdominal MRI is becoming more frequently used for the evaluation of IBD patients. Aim of this study was to investigate the role of MRI in IBD for the assessment of disease activity in comparison with faecal calprotectin levels.

Diffuse abdominal hydatidosis: role of magnetic resonance imaging.

Hydatid cyst disease still is a serious public-health problem in endemic areas. It is a tissue infestation caused by the larval stage of a parasite, Echinococcus granulosus. Although liver and lung are the most commonly involved organs, hydatid disease can occur in all viscera and soft tissues.
