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).
Treatment with DHEA, which is also bioidentical, is an integral component of any comprehensive hormone restoration regimen. On the other hand, some forms of conventional hormone replacement therapy utilize hormones that are not identical to those produced by humans and are either derived from animals or synthesized.ince DHEA-S is more abundant in the bloodstream than DHEA (Traish 2011; Savineau 2013), simple blood tests to measure DHEA-S concentrations can be integrated into any healthy aging strategy for both men and women.
