A new catch word diffuses over the landscape of science and is more and more frequently
encountered in a number of disciplines. The term" network" seems to match a growing need
for the de-mystification of complexity in nature and society. Microbiologists are describing …

About 60% of both Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy
(BMD) is due to deletions of the dystrophin gene. For cases with a deletion mutation, the
“reading frame” hypothesis predicts that BMD patients produce a semifunctional, internally …

The purpose of this work was to determine the rate and extent of bone loss and recovery
from long‐term disuse and in particular from disuse after exposure to weightlessness. For
this purpose, bed rest is used to simulate the reduced stress and strain on the skeleton. This …

Heart induction in Xenopus occurs in paired regions of the dorsoanterior mesoderm in
response to signals from the Spemann organizer and underlying dorsoanterior endoderm.
These tissues together are sufficient to induce heart formation in noncardiogenic ventral …

The loss of bone and muscle is a major concern for long duration space flight. In December
of 1989, we established a collaboration with Russian colleagues to determine the bone and
lean tissue changes in cosmonauts before and after flights on the Mir space station lasting 4 …

To evaluate the role of glucagon in the pathogenesis of diabetic ketoacidosis in man, we
studied the effect of suppression of glucagon secretion by somatostatin on changes in
plasma β-hydroxybutyrate and glucose concentrations (as well as changes in their …

This work reports on the muscle loss and recovery after 17 wk of continuous bed rest and 8
wk of reambulation in eight normal male volunteers. Muscle changes were assessed by
urinary levels of 3-methylhistidine (3-MeH), nitrogen balance, dual-photon absorptiometry …

Purpose In 2003, we described initial use of team‐based learning (TBL) at 10 medical
schools. The purpose of the present study was to review progress and understand factors
affecting the use of TBL at these schools during the subsequent 2 years. Methods …
