Furthe.more. following the.addition of e.oge.ous ATP, an inositol trisphosphate.re.e.tor （IP3R） agonist, small Ca2＋transie.ts we.e.ge.e.ate. from day 1 onward. That ATP was inducing Ca2＋ re.e.se.from functional IP3Rs was de.onstrate. by tre.tme.t with 2-APB, a known IP3R antagonist. In contrast, following tre.tme.t with caffe.ne. a ryanodine.re.e.tor （RyR） agonist, a minima/Ca2＋ re.ponse.was obse.ve. at day 8 of diffe.e.tiation only. Thus, our data indicate.that unlike.RyRs, IP3Rs are.pre.e.t and continually functional at the.e.e.rly stage. of cardiomyocyte.diffe.e.tiation.

选择一些经验公式对48个来自全国的无烟煤煤样的发热量实测值的可靠性进行了检验,发现仅凭一两个经验公式的检验结果很难对实测结果的可靠性作出正确的评价,不同经验公式的检验结果有时具有很大差异.某个样品实测值在通过经验公式检验时出现了偏差超标值,而在用另一经验公式检验时其偏差却很低.总的来说,利用元素指标经验公式对样品发热量进行计算检验时,其计算值与实测值偏差一般小于工业分析指标经验公式,而不同矿区经验公式的准确性比一般经验公式高,对来自不同矿区的样品实测发热量采用矿区专用公式进行检验审核会更好.
