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)
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)
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)
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)
