BACKGROUND: Ablation targeting complex fractionated atrial electrograms (CFAEs) or high dominant frequency (DF) sites is generally effective for persistent atrial fibrillation (AF). CFAEs and/or high DF sites may exist in low-voltage regions, which theoretically represent abnormal substrates. However, whether...

Ogawa M, Kitamura H.
PMID: 24311174
Planta. 1980 Feb;147(5):495-9. doi: 10.1007/BF00380193.

4-Ethoxy-1-(p-tolyl)-s-triazine-2,6(1H,3H)-dione (TA) promoted mesocotyl growth in dark-grown rice (Oryza sativa L.) seedlings. In cultivars of the japonica type TA alone showed a small promotive effect and TA+gibberellic acid(GA3) had a marked synergistic effect, while in other cultivars, mostly of...
