Correlation of dietary aflatoxin B1 levels with excretion of aflatoxin M1 in human urine.
Corn and peanut oil (total, 253 samples) were collected from 32 households in Fushui county of the Guangxi autonomous region of the People's Republic of China, where high liver cancer incidence hasExpand
Molecular dosimetry of urinary aflatoxin-DNA adducts in people living in Guangxi Autonomous Region, People's Republic of China.
Hepatocellular carcinoma is one of the five leading human cancers causing at least 250,000 deaths each year. One of the major risk factors for this disease is exposure to dietary aflatoxins, and theExpand
Serum albumin adducts in the molecular epidemiology of aflatoxin carcinogenesis: correlation with aflatoxin B1 intake and urinary excretion of aflatoxin M1.
Aflatoxin-serum albumin adducts in the blood of 42 residents of Guangxi Province, People's Republic of China, were determined and compared with intake of aflatoxin B1 (AFB1) and excretion ofExpand
Acetone, Isopropanol, and Butanol Production by Clostridium beijerinckii (syn. Clostridium butylicum) and Clostridium aurantibutyricum.
Thirty-four strains representing 15 species of anaerobic bacteria were screened for acetone, isopropanol, and n-butanol (solvent) production. Under our culture conditions, several strains ofExpand
Purification and characterization of a primary-secondary alcohol dehydrogenase from two strains of Clostridium beijerinckii.
Two primary alcohols (1-butanol and ethanol) are major fermentation products of several clostridial species. In addition to these two alcohols, the secondary alcohol 2-propanol is produced to aExpand
The presence of five nifH-like sequences in Clostridium pasteurianum: sequence divergence and transcription properties.
The nifH gene encodes the iron protein (component II) of the nitrogenase complex. We have previously shown the presence in Clostridium pasteurianum of two nifH-like sequences in addition to the nifH1Expand
Butanol-Ethanol Dehydrogenase and Butanol-Ethanol-Isopropanol Dehydrogenase: Different Alcohol Dehydrogenases in Two Strains of Clostridium beijerinckii (Clostridium butylicum).
Alcohol-producing strains of Clostridium beijerinckii (Clostridium butylicum) produce, besides acetone, either n-butanol and ethanol or n-butanol, ethanol, and isopropanol as their characteristicExpand
Inhibition of hydroxymethylglutaryl-coenzyme A synthase by L-659,699.
A beta-lactone isolated from Fusarium sp. has been shown to be a potent specific inhibitor of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase [(S)-3-hydroxy-3-methylglutaryl-CoAExpand
Acidic Conditions Are Not Obligatory for Onset of Butanol Formation by Clostridium beijerinckii (Synonym, C. butylicum).
Factors that may initiate the metabolic transition for butanol production were investigated in batch cultures of Clostridium beijerinckii (synonym, Clostridium butylicum) VPI 13436. CulturesExpand
Inhibition of methylene blue formation during determination of the acid-labile sulfide of iron-sulfur protein samples containing dithionite.
Abstract The acid-labile sulfide content of iron-sulfur proteins is commonly determined colorimetrically by reacting the released sulfide with N,N′ -dimethyl- p -phenylenediamine and FeCl 3 , underExpand
