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) is produced by the pituitary gland, a tiny organ located below the brain and behind the sinus cavities. TSH stimulates the thyroid gland to release the hormones thyroxine (T4) and triiodothyronine (T3) into the blood. These thyroid hormones help control the rate at which the body uses energy. This test measures the amount of TSH in the blood. TSH, along with its regulatory hormone thyrotropin releasing hormone (TRH), which comes from the hypothalamus, is part of the feedback system that the body uses to maintain stable amounts of thyroid hormones in the blood.
