Pulmonary embolism associated with the use of anabolic steroids.

We present the case of a 56-year-old man with deep vein thrombosis (DVT) and pulmonary embolism (PE). He had been given intramuscular injections of testosterone and the anabolic-androgenic steroid nandrolone, due to a muscle injury, a total of three times prior to manifestation of the symptoms. An ultrasonographic examination of the right leg revealed a DVT and computed tomography of the pulmonary arteries showed PE.

Genetic design for facilitated production and recovery of recombinant proteins in Escherichia coli.

Genetic strategies have been used for more than two decades to improve bacterial bioprocesses and to simplify recovery procedures. Such strategies include the design of efficient expression vectors and the improvement of bacterial production strains in different ways, e.g.
