Artificial Muscles Powered by Glucose.

Untethered actuation is important for robotic devices to achieve autonomous motion, which is typically enabled by using batteries. Using enzymes to provide the required electrical charge is particularly interesting as it will enable direct harvesting of fuel components from a surrounding fluid. Here, a soft artificial muscle is presented, which uses the biofuel glucose in the presence of oxygen.

Polymorphism of the CLDN5 gene and Schizophrenia in an Iranian Population.

Background: The gene coding claudin (CLDN5) is located on 22q11. Since the proteins of CLDN5 family are a ma-jor component for barrier-forming tight junctions, it may be important to test whether or not the CLDN5 locus could be associated with schizophrenia.

Method: A total of 150 individuals affected with schizophrenia and 150 healthy persons were recruited.
