Using a probe and procedure developed for the Abbott TOx analyzer, we investigated the influence of albumin on fluorescence polarization of amniotic fluid. Polarization readings increased when albumin was added to either “mature” or “immature”amnioticfluids. Albumin added to a fraction rich in lamellar bodies (10 000 x g pellet) greatly increased polarization readings, but albumin added to the ...

Certain organic carbon moieties in drinking source waters of the Sacramento-San Joaquin Delta can react with chlorine during disinfection to form potentially carcinogenic and mutagenic trihalomethanes. The properties of reactive organic carbon in Delta waters, particularly those of soil origin, have been poorly understood. This study attempts to characterize trihalomethane reactivity of soil or...

Cotton (Gossypium herbaceum L.) fiber development consists of a fiber elongation stage (up to 20 d post-anthesis) and a subsequent cell wall thickening stage. Cell wall analysis revealed that the extractable matrix (pectic and hemicellulosic) polysaccharides accounted for 30-50% of total sugar content in the fiber elongation stage but less than 3% in the cell wall thickening stage. By contrast,...

BACKGROUND The objectives of these laboratory experiments were: (1) to assess bromoxynil sorption, mineralization, bound residue formation and extractable residue persistence in a Dundee silt loam collected from 0-2 cm and 2-10 cm depths under continuous conventional tillage and no-tillage; (2) to assess the effects of autoclaving on bromoxynil mineralization and bound residue formation; (3) to...

Explosives in soils can present environmental problems for military installations. Fine, mobile particles represent the most reactive fraction of the soil and, therefore, are expected to adsorb explosives and potentially facilitate their transport. The objective of this study was to determine the relative significance of phyllosilicate clay, organic matter, and two forms of extractable iron in ...

We have isolated from pathological sera a bilirubin fraction (delta) that is very tightly, if not covalently, bound to protein, most likely albumin. This delta fraction absorbed at a lambda max of 433 nm in the visible spectrum, between the lambda max of unconjugated (alpha) and that of conjugated (Bc) bilirubin when measured in solutions containing albumin. However, unlike the other bilirubin ...

Lingonberry (Vaccinium vitis-idaea L.) is a small northern fruit that has been harvested historically by native North Americans and Northern Europeans. These berries have been traditionally consumed as food and for medicinal use. Lingonberries are reported to be rich in vitamin C, benzoic acid, and anthocyanins, which have been implicated in health benefits associated with the consumption of li...

Capillary electrophoretic profiling of hair fractions obtained by 0.25 M HCl treatment of the tissue with subsequent extraction of the solubilized fraction with chloroform-isopropanol (9:1, v/v) revealed clear differences between hair obtained from alopecia areata affected laboratory rats (both in hair obtained from non-affected areas and hair growing on once hairless patches) and controls. Dif...
