Estrogen-vitamin D interaction in multiple sclerosis

The authors speculate that estrogen levels are likely to influence MS onset through an effect on the immune system. Read the rest of this entry »

Ovarian steroid hormones differentially regulate thrombospondin-1 expression

12 03 2010

To the Editor:

(1) which reported that thrombospodin-1 (TSP-1), a multifunctional extracellular naturally occurring angiostatic protein is differentially regulated by ovarian steroids. Although it is of great clinical value to understand the mechanism(s) involved in TSP-1 regulation by ovarian steroidal hormones especially in relation to how it is involved in endometriosis. However, there are some points we would like to raise regarding the study of Tan et al. (1). Read the rest of this entry »

Endometrial preparation for in vitro maturation treatment
