Serum samples were collected between 24 and 48 h of age
from 408 Hereford calves of a selection experiment and from 200
Angus, Hereford and Red Poll calves of another experimental
population (Germ Plasm Utilization project). Concentrations of
Immunoglobulin G₁ (IgG₁) were determined by single radial
immunodiffusion. Breed or selection...
Thirty-seven Yorkshire sows were bred to one of six boars; 34 of the sows were verified pregnant at 42 d of gestation. These sows were innoculated with ovine serum albumin (OSA) in Freunds' complete adjuvant at 65 d and later given a second injection in Freunds.' incomplete adjuvant 93 d....
The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'.
The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...
A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...
A high performance liquid chromatography (HPLC)
procedure using a LiChrosorb-NH₂ column and a eluant
buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH
5.95, was developed for the successful separation and
determination of ascorbic and erythorbic acids in selected
food samples.
Application of the method, which is sensitive, rapid
and...
