Inositol 1,4,5-trisphosphate activates a channel from smooth muscle sarcoplasmic reticulum.

abstract：:One of the main unanswered questions in solar physics is why the Sun's outer atmosphere is hotter than its surface. Theory predicts abundant production of high-frequency (10-50 mHz) acoustic waves in subsurface layers of the Sun, and such waves are believed by many to constitute the dominant heating mechanism of the c...
