In order for the limb to be useful in the evaluation of early determinants of morphogenesis, it is necessary to understand some of the characteristics associated with "limbness" and, more importantly at the beginning at least, it is necessary to know what regions of the early embryo exhibit limbness qualities. Previous investigators have assumed, without(More)
BACKGROUND People who eat more fiber often have a lower body weight than people who eat less fiber. The mechanism for this relationship has been explained, in part, by increased satiety, which may occur as a result of changes in appetite-suppressing gut hormone levels, and decreases in food intake at subsequent meals.

The impact of oligofructose (OF) intake on stool frequency has not been clearly substantiated, while significant gastrointestinal (GI) symptoms have been reported in some individuals. The aim of the present study was to determine the effects of OF on stool frequency and GI symptoms in healthy adults. In an 8-week, randomised, double-blind, parallel-arm(More)
Harrison (1918: J. Exp. Zool. 25: 413-461) described a developmental field as an "equipotential self-differentiating system." The present study was undertaken to address the question: To what extent can be pre-limb territory of a chick embryo be considered a developmental field? To what extent is the chick pre-limb territory an equipotential(More)
