Placental weight and mortality in premenopausal breast cancer by tumor characteristics [PDF]

, 2013
Placental weight may be regarded as an indirect marker of hormone exposures during pregnancy. There is epidemiological evidence that breast cancer mortality in premenopausal women increases with placental weight in the most recent pregnancy.

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

Molecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

Effects of Levonorgestrel and progesterone on Oviductal physiology in mammals

Reproductive Biology and Endocrinology, 2018
Background Our previous study indicated that emergency contraception, including levonorgestrel and progesterone, could lead to ectopic pregnancy following contraception failure. However, our understanding of the effects of levonorgestrel and progesterone

Progesterone activation of β1-containing BK channels involves two binding sites

Nature Communications, 2023
Progesterone (≥1 µM) is used in recovery of cerebral ischemia, an effect likely contributed to by cerebrovascular dilation. The targets of this progesterone action are unknown.

Hypothalamic effects of progesterone on regulation of the pulsatile and surge release of luteinising hormone in female rats

Scientific Reports, 2017
Progesterone can block the oestradiol-induced GnRH/LH surge and inhibit LH pulse frequency. Recent studies reported that progesterone prevented premature LH surges during ovarian hyperstimulation in women. As the most potent stimulator of GnRH/LH release,

Progesterone and Follicle Stimulating Hormone interact and promote goat preantral follicles survival and development in vitro

Pesquisa Veterinária Brasileira, 2012
We investigated the effects of progesterone and follicle stimulating hormone (FSH) on survival and growth of caprine preantral follicles. Pieces of ovarian tissue were cultured for 1 or 7 days in minimum essential medium (MEM) alone or containing ...
