Then there are the actual studies performed on pregnant women and new mothers, which are ambiguous. Some show memory impairments, especially toward the end of pregnancy, when (psychologists theorize) the brain undergoes a process of neural reprogramming as it prepares to nurture the new baby.
At present it is unknown whether these effects are due to direct effects of growth hormone on hematopoietic cells or if they are caused by the induction of insulin-like growth factor-1 (IGF-1) synthesis.n support of the second possibility, we have induced apoptosis of both nonadherent bone marrow cells and a myeloid progenitor cell line by depriving these cells of CSFs. Preliminary results indicate that addition of IGF-1 to these cells reduces apoptotic cell death by 50%.
Thyroid stimulating hormone (TSH), also known as thyrotropin, is produced by the pituitary gland in the brain and causes the thyroid to make thyroid hormone. When there is not enough thyroid hormone in the body, the pituitary makes more TSH, which tells the thyroid to make and release more thyroid hormone.
