Recombinant tissue plasminogen activator (rt-PA) is currently the only approved drug for ischemic stroke treatment, with a dose of 0.9 mg/kg. Since the fibrinolytic activity of rt-PA has been reported in vitro to be 10-fold less potent in rodent than in human, in most in vivo experimental models of cerebral ischemia rt-PA is used at 10 mg/kg. The purpose of(More)
Although intracerebral haemorrhage (ICH) entails the highest rates of mortality and disability of all stroke subtypes, efficient neuroprotective therapy is still needed. As functional recovery is a major endpoint in clinical trials, preclinical studies must demonstrate the potential of drugs to improve the sensorimotor and cognitive function of animals. In(More)
Recombinant tissue plasminogen activator (rt-PA) is the only pharmacological treatment approved for thrombolysis in patients suffering from ischemic stroke, but its administration aggravates the risk of hemorrhagic transformations. Experimental data demonstrated that rt-PA increases the activity of poly(ADP-ribose)polymerase (PARP). The aim of the present(More)
Numerous industrial bacteria generate hydrogen peroxide (H(2)O(2)), which may inhibit the growth of other bacteria in mixed ecosystems. We isolated spontaneous oxidative-stress-resistant (SpOx) Lactococcus lactis mutants by using a natural selection method with milk-adapted strains on dairy culture medium containing H(2)O(2). Three SpOx mutants displayed(More)
