Low estradiol levels in women of reproductive age having low sleep variation.
Higher exposure to light at night, for example, owing to night shift work or decrease in sleep duration, may suppress melatonin production, which in turn may increase the reproductive hormone levels. High levels of steroid hormones, especially estrogens, may be associated with an increase of the breast cancer risk. This study investigated whether variation in the sleep duration during one entir...

The suppressive effect of exercise on estradiol levels in women is well documented, but it is unknown whether habitual (i.e. typical daily) physical activity has a similar effect. Epidemiological data suggest that physical activity is one of the few ...
متن کاملLow 17β-estradiol Levels Are Better Inducers of Regulatory Conditioned T Cells In-Vitro
Background: 17β-estradiol (E2) has been known to modulate immune response. Recent studies indicate that E2 at pregnancy level plays a role in regulating T cell response. Objective: To investigate the optimum dose of E2 (from 10-9 to 10-7 M) in mediating the generation of regulatory T cells (Tregs), using naïve human CD4+ T cells from healthy women. Methods: Naïve peripheral T cells were purifie...
