1. C(14)-labeled beta-aminopropionitrile distributed throughout the egg contents within 10 minutes postinjection. By ion exchange chromatography and electrophoretic analysis three major components of the extractable dialyzable radioactive material could be demonstrated, representing at least 80 per cent of the total. The acidic and basic components were identified as beta-aminopropionitrile and...

Whole grain cereals contain a wide range of phytochemicals and it is often difficult to ascribe protective effects on metabolic health to any one particular constituent. The interactions among bioactive components, which contribute highly to the total antioxidant capacity of cereals, represent the first step in the evaluation of food potential health benefits. This research focused on the deter...

Shifts in manure phosphorus (P) chemical forms and pool sizes induced by water treatment residuals and industrial mineral by-products are largely undefined. We conducted a manure P fractionation study to determine mechanisms of reduction of dissolved reactive phosphorus (DRP) in poultry manure upon mineral by-product additions. The effects of composting on the P immobilization efficacy of the b...

Two pools of plant-derived C31 n-alkane occurring respectively as free and humin-bound forms in the same soil have been distinguished by C/C analyses. The results show that the humin-bound molecule is on the average 7 years older than the free molecule. These findings indicate that apolar organic substances can be trapped temporarily into the soil matrix by weak forces. Dans un même sol, la ten...

Security against selective opening attack (SOA) requires that in a multi-user setting, even if an adversary has access to all ciphertexts from users, and adaptively corrupts some fraction of the users by exposing not only their messages but also the random coins, the remaining unopened messages retain their privacy. Recently, Bellare, Waters and Yilek considered SOA-security in the identity-bas...

Apoliporotein B (apoB) was measured in buffer-extracted homogenates of grossly normal and artherosclerotic human aortic intima by means of an electroimmunoassay procedure. The apoB values which were expressed as microgram per mg tissue dry weight, varied widely, ranging from 0.34 to 18.45 in normal intima and from 0.8 to 12.5 in fatty fibrous plaques. No consistent differences in apoB content w...

To develop a system for studying the regulation of adipose tissue lipoprotein lipase (LPL) in human cells, we isolated cells from the stromalvascular fraction of human adipose tissue and propagated them in tissue culture. These cells were cultured in medium containing fetal bovine, horse, or human sera in the absence or presence of aminoglycoside antibiotics. After the cells had been at conflue...

[1] Surface sediments along a transect from an abyssal site in the northeastern Pacific (Station M, 34 500N, 123 000W) to a small mountainous river on the California coast (Santa Clara River) were studied to investigate the sources and cycling of organic matter on the continental margin. Sediment samples were separated into organic compound fractions (extractable lipids, amino acids (THAA), car...
