Ase is definitely an vital function from the ribbon. Thus, it is actually tempting to speculate that Piccolino plays a function in these processes. With the identification of Piccolino, a novel Pclo splice variant specifically expressed at retinal ribbon synapses, the stage is set for further functional studies of the ribbon in general and of Piccolino in unique.AcknowledgmentsWe thank Dr. D.

Delayed postanoxic leukoencephalopathy (DAL) has been reported with intoxication by carbon monoxide, narcotics, along with other toxins. OBJECTIVE–To investigate the metabolic derangement of the white matter (WM) and blood?brain barrier (BBB) soon after DAL triggered by methadone overdose. Style, SETTING, AND PATIENTS–Case report of two sufferers with DAL following a single dose of “diverted” methadone utilised for discomfort handle. RESULTS–In both situations brain magnetic resonance imaging (MRI) revealed initial in depth bilateral restricted diffusion lesions inside the WM. Follow-up MRI using proton magnetic resonance spectroscopic imaging (1H-MRSI) showed markedly reduced N-acetylaspartate and larger choline inside the WM. BBB permeability, calculated by Patlak graphical evaluation of MRI T1 data obtained right after contrast agent injection, showed disruption in the BBB within the WM lesions, which persisted longer than a year in 1 patient. Neuropsychological evaluation showed executive dysfunction in both patients. After 1 year, one patient recovered whereas the second remained impaired. CONCLUSIONS–Methadone overdose may cause DAL with profound disturbances of neural metabolism and the BBB. The time course of those disturbances may be monitored with MR strategies.
