Sera of all male donors appearing at the blood bank of a regional hospital in Northwest Ethiopia in 1994 (n = 1022) and 1995 (n = 1164), were screened for the presence of human immunodeficiency virus (HIV-1) and treponemal antibodies. Additionally, screening for hepatitis B surface antigen (HBsAg) was carried out on 549 consecutive sera. In 1995, the crude(More)
BACKGROUND Two German sisters aged 14 and 17 y were admitted to the Tübingen eye hospital with a history of night blindness. In both siblings, plasma retinol binding protein (RBP) concentrations were below the limit of detection (<0.6 micromol/L) and plasma retinol concentrations were extremely low (0.19 micromol/L). Interestingly, intestinal absorption of(More)
The effect of vitamin A on chicken intestinal mucosal morphology and functionality was tested in relation to severe and mild vitamin A deficiency and vitamin A repletion. Compared with rats and mice, chickens have a very quick response to a deficient dietary intake. Severe vitamin A deficiency altered the small intestine of chickens at both the biochemical(More)
OBJECTIVE To determine the prevalence, importance, and the order of frequency of IgE-mediated food allergens among infants and young children in Israel. STUDY DESIGN AND PATIENTS In a cross-sectional study, the prevalence of IgE-mediated food allergy was investigated in 9070 infants and young children (0-2 years) who were followed-up at 23 Family Health(More)
Polyunsaturated fatty acids (PUFA) are highly abundant in brain tissue, and docosahexaenoic acid (DHA) might protect cells from oxidative stress (OS) during inflammation and demyelinating disorders, but also might exert pro-oxidant effects. Here we investigated if PUFA supplements lead to heat shock protein induction, altered cell survival properties and(More)
UNLABELLED To evaluate the diagnostic information gained from hepatobiliary scanning in infants, we reviewed 86 consecutive infants who were < or = 4 mo old and were treated for conjugated hyperbilirubinemia at the Hospital for Sick Children in Toronto between 1985 and 1993 and who had technetium iminodiacetic hepatobiliary scanning and a percutaneous liver(More)
Iron supplementation is one of the principal therapies in inflammatory bowel disease. Iron is a major prooxidative agent; therefore therapeutic iron as well as heme iron from chronic mucosal bleeding can increase the iron-mediated oxidative stress in colitis by facilitating the Fenton reaction, namely production of hydroxyl radicals. In the present study(More)
The etiology and pathogenesis of inflammatory bowel disease are still not fully understood. However, evidence from both animal models and clinical observations suggests luminal bacteria as the most probable inducer of this disease. The intestinal bacterial microbiota may be modified by dietary addition of viable probiotic bacteria, thereby constituting an(More)
