Phones that belong to the same phoneme, such as [t] and [tÊ°] for English /t/ , are called allophones. A common test to determine whether two phones are allophones or separate phonemes relies on finding minimal pairs: words that differ by only the phones in question.
Bioidentical hormone replacement therapy (BHRT), also known as bioidentical hormone therapy or natural hormone therapy, is a poorly defined term referring to the use of hormones that are identical, on a molecular level, with endogenous hormones in hormone replacement therapy.HRT is a form of alternative medicine, and has been promoted as a panacea for many diseases rather than a means of relieving the symptoms of menopause and/or reducing the risk of osteoporosis (the goals of traditional hormone replacement therapy).
Not only are bioidentical hormones promoted to fight menopausal symptoms, but also as a treatment that can reduce the risk of osteoporosis. Bioidentical Hormones and Hair Loss . Some researchers believe that bioidentical hormones do fight the symptoms of menopause, hair loss included. Bioidentical hormones have the exact molecular structure of the hormones that a woman's body produces naturally. In other words, these hormones are no different from the hormones that women's bodies produce from about age 12 through 51. Bioidentical hormones are just as effective in eliminating symptoms of menopause as synthetic hormones at balancing the fluctuating hormones that cause hair loss and other menopausal symptoms.
