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).
According to the North American Menopause Society* (www.menopause.org), the term bioidentical is used to describe hormones that are chemically identical to the hormones produced naturally by a womanâs ovaries.. The most common form of estrogen produced by a woman's ovaries is estradiol.
