Primary regenerants (1190) of a tall traditional salt tolerant rice cultivar pokkali were produced through in vitro culture from mature seed derived calli of fourth subculture. Out of 35000 SC2 regenerants, 26 promising lines with superior agronomic traits were chosen initially for evaluation. SC3 and SC4 generations were stringently evaluated under hydroponics with excess salt stress as well a...

In the management of acute ischemic stroke, guideline adherence is often suboptimal, particularly for intravenous thrombolysis or anticoagulation for atrial fibrillation. We sought to improve stroke care quality via a collaborative model, the Breakthrough Series (BTS)-Stroke activity, in a nationwide, multi-center activity in Taiwan. A BTS Collaborative, a short-term learning system for a large...
