Is abnormally persistent latent inhibition induced by MK801 reversed by risperidone and by positive modulators of NMDA receptor function : differential efficacy depending on the stage of the task at which they are administered?
These results support the validity of MK801-induced persistent LI as a model of negative/cognitive symptoms in SZ and indicate that this model may have a unique capacity to discriminate between typical APDs, atypical APDs, and glycinergic compounds, and thus, foster the identification of novel treatments for SZ.
CA19-9 levels are high in the cyst fluid and serum of polycystic liver disease patients due to production and secretion by cyst epithelia. It does not reflect malignancy in these patients and may be of value as a biomarker for intervention efficiency assessment.
