Emulsion Definition. An emulsion is a colloid of two or more immiscible liquids where one liquid contains a dispersion of the other liquids. In other words, an emulsion is a special type of mixture made by combining two liquids that normally don't mix. The word emulsion comes from the Latin word meaning to milk (milk is one example of an emulsion of fat and water). The process of turning a liquid mixture into an emulsion is called emulsification.
During the drug testing process, the medicine in Saxenda Â® caused rats and mice to develop tumors of the thyroid gland. Some of these tumors were cancers. It is not known if Saxenda Â® will cause thyroid tumors or a type of thyroid cancer called medullary thyroid cancer in people.
Investigators at Harvard University also contributed to the study. The research, conducted in mice and in human brain tissue, may help to explain the failures in recent years of large-scale clinical trials attempting to slow the progression of Alzheimerâs by pharmacologically ridding the brain of amyloid plaques.
