Abstract: The present disclosure provides host cells, e.g., bacterial cells, that comprise a methionine decarboxylase enzyme for the treatment of diseases and disorders associated with methionine metabolism in a subject. The disclosure further provides pharmaceutical compositions and methods of treating disorders associated with methionine metabolism, such as homocystinuria.

Abstract: An undercarriage having an undercarriage leg carrying at least one stub, the stub being provided with a hollow element. An onboard device comprises a bar and at least one measurement unit. The measurement unit comprises two pieces of equipment, one of the pieces of equipment comprising a measurement member and one of the pieces of equipment comprising a wall. One of the two pieces of equipment is secured to the bar and one of the two pieces of equipment is secured to the hollow element, the onboard device including a test system. The test system has movement means for imparting, on request, relative movement between the pieces of equipment in order to detect a potential malfunction and in order to generate an alert if a malfunction is detected.

Abstract: A monitor system for monitoring the reliability of at least one piece of electronic equipment installed in an aircraft. In order to monitor each piece of electronic equipment, such a monitor system comprises: monitor means for measuring variations of at least one state parameter P as a function of time t; concatenation means for generating data groups (ti, Pi, Sj); transmission means for transmitting the data groups (ti, Pi, Sj) to a centralized unit; first computation means for determining an observed reliability Robs of the or each piece of electronic equipment; second computation means for determining an expected reliability Rexp of the or each piece of electronic equipment; comparator means for comparing the observed reliability Robs with the expected reliability Rexp of the or each piece of electronic equipment; and warning means.
