Metazoan genomes contain large numbers of genes that participate in responses to environmental stressors. We surveyed the sea urchin Strongylocentrotus purpuratus genome for homologs of gene families thought to protect against chemical stressors; these genes collectively comprise the 'chemical defensome.' Chemical defense genes include cytochromes P450 and(More)
Abnormal fibrosis occurs during chronic hepatic inflammations and is the principal cause of death in hepatitis C virus and schistosome infections. Hepatic fibrosis (HF) may develop either slowly or rapidly in schistosome-infected subjects. This depends, in part, on a major genetic control exerted by genes of chromosome 6q23. A gene (connective tissue growth(More)
BACKGROUND Retinoblastoma (RB) is a rare and unique cancer that affects the eyes of very young children. There are few reports on RB in Sudan. MATERIALS AND METHODS We performed a retrospective study of data from patients diagnosed with retinoblastoma between January 1999 and December 2009 at the National Cancer Institute in Gezira (NCI-Gezira). RESULTS(More)
UNLABELLED Interleukin (IL)-22 acts on epithelia, hepatocytes, and pancreatic cells and stimulates innate immunity, tissue protection, and repair. IL-22 may also cause inflammation and abnormal cell proliferation. The binding of IL-22 to its receptor is competed by IL-22 binding protein (IL-22BP), which may limit the deleterious effects of IL-22. The role(More)
The pharyngeal pouch (Zenker's diverticulum) is a diverticulum of the mucosa of the pharynx, just above the cricopharyngeal muscle (i.e. above the upper sphincter of the oesophagus). It occurs commonly in elderly patients (over 70 year) and the typical symptoms include dysphagia, regurgitation, chronic cough, aspiration and weight loss. We are reporting a(More)
