Even the bra industry has admitted that a bra will NOT keep breasts from sagging, and that it will only hold them into a position that a particular bra design is designed to do, while the bra is being worn, and when the bra is removed, the breasts will no longer retain that position.
Abstract. Drugs may interact with other drugs or any diet or dietary supplement taken at the same time. Interactions may be pharmacodynamic in which interaction is close to the target organ and involves direct antagonism or addition of pharmacological properties.rug interactions are usually described as pharmacodynamic (where changes in drug action occur in the area of the target tissue) or pharmacokinetic (when one drug affects the absorption, distribution or excretion of another).
Another textbook I consulted defined chemical property this way: chemical properties describe the way a substance may change or react to form other substances. One example was given: flammability-the ability of a substance to burn in the presence of oxygen. Some substances (wood, alcohol) are very flammable, others are not.
