In the Drosophila leg, activation of Notch leads to the establishment of the joints that subdivide the appendage into segments. We find that mutations in bowl result in similar phenotypes to Notch, causing fusion and truncations of tarsal segments (tarsomeres) and, like its close relative Odd-skipped, Bowl is produced in response to Notch signalling at a subset of segment boundaries. However, d...

Ultrasonography and computed tomography performed subsequent to admission showed no narrowing or distension of the bile ducts.

Introduction While scientific performance is an important aspect of a stable and healthy economy, measures for it have yet to gain their place in economic country profiles. As useful indicators for this performance dimension, this paper introduces the concept of milestones for research excellence, as points of transition to higher-level contributions at the leading edge of science. The proposed...
