OBJECTIVE To demonstrate the technique of stereotactic microsurgical endoscopic removal of intraventricular tumors or colloid cysts assisted by intraoperative computed tomography. METHODS We adapted a tubular "ventriculoport" for stereotactic insertion of an endoscope into the ventricle. This facilitated microsurgical resection of 14 intraventricular(More)
Radiosurgery is a minimally invasive technique designed to elicit a specific radiobiologic response at the target tissue using focused ionizing radiation delivered in single procedure. Radiosurgery was originally devised to treat intracranial lesions by delivering a high dose of radiation precisely at the intracranial target using stereotactic guidance. The(More)
The response to melatonin expression is one way that circadian rhythms of many biological processes are regulated. To evaluate the relationship between the melatonin receptor 1A (MTNR1A) gene and reproductive performance, records were compared in Dorset and 3/4-Dorset x 1/4-East Friesian ewes expressing different genotypes at the MTNR1A gene in the Cornell(More)
