月经

  1. 月经期就是指女性来月经的这段时间。这段时间由于妊娠没有发生，在脑垂体激素的调控下，卵巢中雌激素和孕激素的分泌量下降，子宫内膜供血小动脉发生痉挛收缩，然后破裂，子宫内膜缺血、坏死和脱落，于是就表现为月经来潮，这个时候女性的皮肤一般会变好。
  2. 月经期之后就是卵泡期了，卵泡期指的是卵泡发育并成熟的阶段，原始卵泡在发育过程中，经历初级卵泡、次级卵泡的不同发育阶段，最终成为成熟的卵泡。高水平的雌激素使子宫内膜的增生，有利于受精卵的着床。 一般历时8到10天。月经刚刚结束的时候。
  3. 排卵期: 排卵期指的是卵泡在黄体分泌高峰的作用下向卵巢表面移动，卵泡壁破裂，出现排卵孔，卵细胞与透明带、放射冠以及卵液排出，这种过程称为排卵。排出的卵细胞被输卵管伞捕捉送入输卵管中。排卵期一般为一周，排卵日只有一日。这段时间因为排卵，所以空了的卵泡就会立刻塌陷、出血、形成血体，然后其中的血液被吸收，形成有分泌作用的黄体。黄体就开始分泌孕激素了。
  4. 黄体期: 排卵之后人体便进入黄体期，残余的卵泡壁内陷，血液进入卵泡腔，凝固形成血体，随着血液被吸收，颗粒细胞与内膜细胞增殖黄体化，形成外观为黄色的黄体。若卵子受精成功，胚胎便分泌HCG使黄体继续发育成为妊娠黄体。排卵之后雌激素下降，但是因为黄体分泌得较多，所以这个时候孕激素也会比较多，能够使子宫内膜有丰富营养，进一步增厚，为妊娠提供稳定的场所。

Memo, 10/30/2021 Zou, Wang, Zheng, Li

  1. Scientific methodology discussion (casual-effect, association/correlation, formal logic, athetic principle, etc)
  2. Project 1: Existing data for analysis
  3. Project 2: ovulation
    • Tao: contact wearables industry
    • Xin: think about experimental design; check out public database for temperature recording; check out Switzerland's paper for open datasets
  4. Next meeting: schedule in group chat
    • bi-weekly meeting at least 9:00 am EST
