The study suggested that a mother's diet as an adult had no effect on her baby's birth weight. Far more important were the mother's health and nutrition as a baby and toddler, and even the grandmother's diet when she was pregnant with the baby's mother.
Synthetic Opal: is created in a Lab, but itsâ properties, chemical, optical and physical, are identical to that of a naturally occurring Opal. Simulated Opal: is also created in a Lab, and is optically identical to natural Opal, but does not have the same physical and chemical characteristics. One of the biggest distinctions, and subject of debate for classification, is what is used in place of water in the Lab Created Opals. The originator of the Synthetic Opal, Pierre Gilson Sr., uses pure silica to fill the gaps between the Opal spheres. Thus creating a product that is 100% Opal.
An Opioid is a chemical substance that has a morphine like action in the body. Opioid's can be classified as natrual, semi-synthetic, and fully-synthetic.Natural opioid's include morphine, codeine, thebaine, and oripavine. Semi-sythetic opioids include hydromorphone, hydrocodone, oxycodone, and heroin.Fully-synthetic opioids include fentanyl, pethidine, methadone, and propoxyphene. Opioid's bind to specific opioid receptors in the central nervous system and in other tissues.pioids work in the body by attaching to the opioid receptors. These receptors are found in the gastrointestinal tract, along the spinal cord and in the brain. The body stops perceiving pain when these receptors are blocked. Another effect of opioids is the feeling of euphoria that is often associated with them.
