Either a single (acute) or repeated daily (chronic) injections (1 injection/day) of 20 mg/kg cocaine for 10 days to rats was found to increase reactive oxygen species production in two dopaminergic brain structures, the frontal cortex and the striatum. We found that the mitochondrial genome was down-regulated after acute cocaine injection. Hydroperoxide and lipid peroxide generation was correlated with an increase in mitochondrial hydrogen peroxide generation and with a reduced functioning of mitochondrial complex I in response to cocaine.

The impact of institutionalization on the carriage of multiresistant bacteria among the elderly was assessed prospectively by comparing the carriage rate in institutionalized patients over 70 years of age to the carriage rate in patients over 70 living at home (58 patients/group). Nares, skin, and rectal swabs were obtained within 24 h of admission to the hospital. Among the 20 carriers identified, 75% came from institutions.
