Enhanced dihydropyridine receptor channel activity in the presence of ryanodine receptor.

abstract：:The factors driving glacial changes in ocean overturning circulation are not well understood. On the basis of a comparison of 20 climate variables over the past four glacial cycles, the SPECMAP project proposed that summer insolation at high northern latitudes (that is, Milankovitch forcing) drives the same sequence o...
