We studied the effectiveness with which various charcoal preparations separate free [3H]pteroylglutamate from that complexed with milk folate binder. We tested, in various concentrations, uncoated charcoals and charcoals coated with dextrans of various molecular weights, or with albumin, hemoglubin, or polyvinylpyrrolidone with an average molecular weight of 40 000. Althouth there was some dist...

outpatient department because of anal bleeding. She had been diagnosedwith ulcerative proctitis about 1 year previously and had experienced intermittent anal bleeding during treatment at a local clinic. She had no significant medication history and in particular had not used laxatives or oral iron. The initial colonoscopy revealed numerous variable-sized areas of black pigmentation in the mucos...

this study has been conducted to evaluate the effectiveness of the local made charcoal tubes against adsorption of benzene, toluene and xylene vapors. results indicate that desorption capacity and the recovery percentage decrease as the benzene, toluene and xylene concentrations and also relative humidity increase. it is concluded that the water vapor is the major interfere in the adsorption of...

BACKGROUND Activated charcoal (AC) is commonly used for the routine management of oral drug overdose. AIM To determine whether the routine use of activated charcoal has an effect on patient outcomes. DESIGN Randomized controlled unblinded trial. METHODS We recruited all adult patients presenting with an oral overdose at The Canberra Hospital, excluding only transfers, late presenters, tho...

All forest fi re events generate some quantity of charcoal, which may persist in soils for hundreds to thousands of years. However, few studies have eff ectively evaluated the potential for charcoal to infl uence specifi c microbial communities or processes. To our knowledge, no studies have specifi cally addressed the eff ect of charcoal on ammonia-oxidizing bacteria (AOB) in forest soils. Con...

Trimethylaminuria (TMAU) is a metabolic disorder characterized by the inability to oxidize and convert dietary-derived trimethylamine (TMA) to trimethylamine N-oxide (TMAO). This disorder has been relatively well-documented in European and North American populations, but no reports have appeared regarding patients in Japan. We identified seven Japanese individuals that showed a low metabolic ca...
