Nov. 5, 2008 -- Two banned obesity drugs may have lingering effects on the heart, according to a new study. The study shows that heart valve problems linked to the banned obesity drugs fenfluramine and/or dexfenfluramine typically last years after stopping those drugs. The FDA ordered fenfluramine and dexfenfluramine off the market in September 1997 after those drugs were linked to heart valve problems. Fenfluramine was one of the ingredients in fen-phen , and dexfenfluramine is closely related to fenfluramine.

Biological technicians also may work in private industry and assist in the study of a wide range of topics concerning mining and industrial production. They may test samples in environmental impact studies, or monitor production processes to help ensure products are not contaminated.iological technicians typically do the following: Set up, maintain, and clean laboratory instruments and equipment, such as microscopes, scales, and test tubes. 1  Gather and prepare biological samples, such as blood, food, or bacteria cultures, for laboratory analysis. 2  Conduct biological tests and experiments.
