OBJECTIVE To assess the effects of participation in an intradialytic exercise program using commonly available measures of physical performance and parameters of nutrition assessment. SESIGN: Performance testing and nutrition assessment were completed on hemodialysis patients who participated in an in-center, intradialytic exercise program. Data were(More)
Although stroke can affect cerebral structure and function, the brain has a potential for plasticity thanks to which some degree of function can be restored. The pathways of such recovery are of great interest, since the dynamics of rewiring of the injured brain may become the basis for designing appropriate strategies of rehabilitation. We investigated the(More)
Spontaneous restorative plasticity is reported frequently after stroke. To test whether conditions in perinfarct cortex facilitate plastic changes, we examined experience-dependent plasticity of cortical functional representation of vibrissae in rat brain after focal photothrombotic stroke. Cortical activation was visualized with [C]2-deoxyglucose. To(More)
Brain injury triggers spontaneous plasticity, often resulting in considerable restoration of function. To investigate mechanisms of this compensatory plasticity we followed changes in the brain's pattern of activation evoked by stimulation of vibrissae, after a focal cortical stroke which destroyed the cortical representation of vibrissae, the barrel(More)
Despite indications that brain plasticity may be enhanced after stroke, we have described impairment of experience-dependent plasticity in rat cerebral cortex neighboring the stroke-induced lesion. Photothrombotic stroke was centered behind the barrel cortex in one cerebral hemisphere of rats. Plasticity of cortical representation of one row of vibrissae(More)
The very large number of medications recognized as hepatotoxic has required the establishment of microcomputerized data file. This file presently indexes 347 active principles contained in more than 1000 patent medications. It may be rapidly examined with microcomputer.
The most severe adverse reactions associated with medicinal treatment of the colon involve pseudomembranous colitis following antibiotic treatment, notably with clindamycin, lincomycin and betalactamine. The frequency of this adverse reaction is poorly defined: 1 per 100 to 1 per 5 000 treatments depending on the study. Lesions are explained by the(More)
