What time is the "biologic zero hour" of circadian variability?

abstract：BACKGROUND:The X-linked angiotensin II type-2 receptor (AT2R) gene 1675G/A polymorphism is located in the short intron 1 of the AT2R gene within a sequence motif conforming to a splice branch site. AT2R is expressed in the human retina, but no previous study examined the association between retinal microvascular phenot...
