Extractable dietary fiber (DF) plays an important role in nutrition. This study on porridge making with whole grain rye investigated the effect of rest time of flour slurries at room temperature before cooking and amount of flour and salt in the recipe on the content of DF components and molecular weight distribution of extractable fructan, mixed linkage (1→3)(1→4)-β-d-glucan (β-glucan) and ara...

Organo-clay complexes in soil play an important role in the immobilization and persistence of xenobiotics. In this study, the fate of 14 C-labeled 4-(3,5-dimethylhept-3-yl)phenol (NP) and 4-chloro-2mehtylphenoxyacetic acid (MCPA) in soil was examined using incubation periods from 1d to 180d (NP) and 1d to 120d (MCPA). Special emphasis was on the distributions of the compounds and its degradatio...

Spectroscopic studies of Parma ham during processing revealed a gradual transformation of muscle myoglobin, initiated by salting and continuing during ageing. Electron spin resonance spectra did, however, conclusively show that the pigment in dry-cured Parma ham at no stage is a nitrosyl complex of ferrous myoglobin as found in brine-cured ham and Spanish Serrano hams. Both near-infra red refle...

Coprecipitates of heavy metals with Fe oxides may form in contaminated soil, water, and sediment systems, particularly when oxidation-reduction processes are occurring. Once formed, coprecipitates with ferrihydrite could limit heavy metal mobility, solubility, toxicity, and bioavailability in geochemical systems. In this study, Cd, Cu, Pb, and Zn were coprecipitated with Fe by titration to pHs ...

A salt-extractable low-molecular-weight fraction has been held responsible for the resistance of cartilage to invasion by malig nant cells. To test this hypothesis, we have confronted in vitro fragments from bovine articular cartilage, from bovine nasal septum, from chick embryonic tibia, or from human knee menis cus with cells from the following malignant lines: LICR-HN-4 human squamous cell c...

Lead-induced inclusion bodies in renal tubular cells of rats have been studied in vitro after isolation by differential centrifugation. The inclusion bodies are insoluble in physiological media but may be dissolved in denaturants like 6M urea and sodium deoxycholate. They contain about 40-50 mug of lead/mg protein, but only about 10% of this is tightly bound. They also contain calcium, iron, zi...

Chromated copper arsenate (CCA)-treated wood was liquefied with polyethylene glycol/glycerin and sulfuric acid. After liquefaction, most CCA metals (98% As, 92% Cr, and 83% Cu) were removed from liquefied CCA-treated wood by precipitation with calcium hydroxide. The original CCA-treated wood and liquefied CCA-treated wood sludge were fractionated by a modified Community Bureau of Reference (BCR...

When Escherichia coli Olll:B4 is exposed briefly to ethylenediaminetetraacetate (EDTA) it releases 30 to 50% of its lipopolysaccharide, determined not only by measuring percentage release of colitose, a sugar unique to this polymer, but also by measuring the amount of phenol-extractable lipopolysaccharide remaining with the cell. The fraction released cannot be significantly increased above 50%...
