Intercellular calcium waves mediate preferential cell growth toward the wound edge in polarized hepatic cells.
During liver regeneration, hepatocytes sense the damage and initiate proliferation of the quiescent cells through poorly understood mechanisms. Here, we have used cultured hepatic cells to study the… Expand

BACKGROUND/AIMS Praeruptorins, a seselin-type coumarin, possess anti-inflammatory and antitumor promoting properties. However, molecular mechanisms through which Praeruptorin-B (Pra-B) exerts an… Expand
Design of the Ring Remote Phosphor Structure for Phosphor-Converted White-Light-Emitting Diodes
A phosphor-converted light-emitting diode structure with an increased phosphor extraction efficiency owing to the ring remote phosphor structure achieves a maximum luminous efficacy of 145 lm/W at 20… Expand
Near-white and tunable electrophosphorescence from bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II)-based organic light emitting diodes
Abstract A new phosphorescent platinum(II)-pyridyltriazolate complex, bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II), Pt(ptp)2, was synthesized and incorporated into organic light emitting… Expand
High efficiency orange‐red phosphorescent organic light emitting diodes based on a Pt(II)‐pyridyltriazolate complex from a structure optimized for charge balance and reduced efficiency roll‐off
We report a high power efficiency (PE) of 44.7 ± 0.5 lm/W, high external quantum efficiency (EQE) of 19.7 ± 0.1% at 500 Cd/m2, and efficiency roll-off of only 4% of the peak value at a useful… Expand
