Fermentation in the large bowel has been postulated to play a protective role against colon cancer. Hydrogen and methane are end products of this fermentation process and are absorbed into the bloodstream and excreted via expired air in the breath. Breath levels of hydrogen and, to a lesser extent, methane correlate strongly with colonic fermentation and may serve as useful biomarkers for this ...

The increased interest in becoming green for consumers and companies is driving groups to develop innovative ways to become more efficient and reduce their waste. Foods past their expiration dates are large sources of waste and are causing food-manufacturing companies to develop waste disposal strategies. Integrating by-products from these companies into animal diets, specifically that of layin...

Cigarette smoking causes an influx of mononuclear phagocytes and polymorphonuclear leucocytes into the lower airways. These cells have altered oxygen metabolism and release more H2O2 than phagocytes from nonsmokers. In this study, we intended to determine whether asymptomatic cigarette smokers exhale more H2O2 than healthy nonsmokers. The content of H2O2 in the expired condensate of 27 nonsmoke...

Expired hydrogen and blood glucose were measured during an oral lactose tolerance test in 163 children aged between 9 months and 14 years. Lactose malabsorption, defined as an abnormal increase in expired H2 during a lactose tolerance test, was found in 54 children. Of these, 30 were found to be lactose intolerant as the increased expired H2 was accompanied by clinical symptoms. The other 109 c...

OBJECTIVE To assess the effects of pre-existing malnutrition on the treatment outcome of children with acute lymphoblastic leukaemia. METHODS One hundred and sixty three patients with Acute Lymphoblastic Leukaemia (ALL) below the age of 14 years with L1 and L2 FAB morphology were included in this study. Treatment protocol used was FBM. Patients were classified according to Waterlow classifica...
