In most cases of shunted hydrocephalus, shunt malfunction is evaluated by clinical examination and neuro-imaging. However if there is a discrepancy between neurological examination and imaging, additional shuntography can be helpful in the evaluation of the shunt function. In our clinic, radionuclide-imaging shuntography using (99m)technetium-pertechnetate(More)
Pineal lesions are rare. Tumours in this location comprise 0.4-1% of intracranial tumours. They grow mainly as solid-mass lesions, and cystic tumours are not common. On MRI, a cystic configuration is associated usually with non-neoplastic pineal lesions rather than with a tumour, but analysis does not allow cystic pineal tumours to be distinguished from(More)
The present study examined the effect of chronic intrastriatal infusion of the dopamine receptor agonist lisuride on apomorphine-induced rotational behaviour and on D2-dopamine receptors in rats with unilateral 6-hydroxydopamine (6-OHDA) lesions of the nigrostriatal dopaminergic pathway. The completeness of the lesion of the right ascending nigrostriatal(More)
Direct infusion of dopamine into the corpus striatum has been proposed as a potential approach for the treatment of Parkinson's disease. The present study examined the effect of intrastriatal dopamine infusion on D2-dopamine receptors in the 6-hydroxydopamine (6-OHDA) lesioned rat brain. The completeness of the 6-OHDA-induced nigrostriatal injury was(More)
The GRASP/Ada project (Graphical Representations of Algorithms, Structures, and Processes for Ada) has successfully created and prototyped a new algorithmic level graphical representation for Ada software, the Control Structure Diagram (CSD). The primary impetus for creation of the CSD was to improve the comprehension efficiency of Ada software and, as a(More)
