Digestion by Barnacle Geese in the Annual Cycle : The Interplay Between Retention Time and Food Quality

J Prop, +1 more
- 01 Jan 1992 - 
TL;DR: This study examined food digestion by free-living barnacle geese Branta leucopsis in relation to food quality and retention time and found enhanced digestion allowed the geese to extend their food spectrum by exploiting mosses, which are, at least temporarily, the only plants available in the summer range.
Journal ArticleDOI

Inhibition of thyrotropin response to thyrotropin-releasing hormone by small quantities of thyroid hormones

TL;DR: The extreme sensitivity of TRH-induced TSH release to inhibition by the chronic treatment with small quantities of triiodothyronine and thyroxine which do not raise serum T(3) and T(4) levels above the normal ranges is demonstrated.

Platelet-derived growth factor enhances bone cell replication, but not differentiated function of osteoblasts.

J M Hock, +1 more
- 01 Mar 1994 - 
TL;DR: The studies show that PDGF-AA and -BB are mitogens affecting multiple bone cells, including those of the osteoblast and osteoclast lineage, and there was no evidence to show that cells incorporating [3H]thymidine differentiated into mature osteoblasts within the time frame of these experiments.
Journal ArticleDOI

Down syndrome and acute leukemia in children: a 10-year retrospective survey from Childrens Cancer Study Group.

TL;DR: Analysis of findings in patients with ANLL provided results similar to those obtained for patients with ALL with regard to clinical outcome after achievement of an initial remission, and there were no significant differences with respect to remission duration, survival, or disease-free survival.
