introduction: loss of inhibitory output from purkinje cells leads to hyperexcitability of the deep cerebellar nuclei (dcn), which results in cerebellar ataxia. also, inhibition of small-conductancecalcium-activated potassium (sk) channel increases firing rate f dcn, which could cause cerebellar ataxia. therefore, sk channel activators can be effective in reducing the symptoms of this disease, ...
In a typical morning in the Cancer Genetics Clinic at The Hospital for Sick Children in Toronto, the following array of patients and families might be seen: a family of three children, all harbouring a mutation of the succinyl dehydrogenase C gene inherited from their father who had had extensive surgery several years ago for a secreting paraganglioma; three families with Li-Fraumeni syndrome, ...
The potential role of immunohistochemistry in making the distinction between primary cerebellar haemangioblastoma and metastatic renal carcinoma was investigated by examining the reaction pattern of 10 cerebellar haemangioblastomas (seven women, three men, aged 20-40 years) and 10 primary renal carcinomas (six men, four women, aged 49-82 years) to a panel of epithelial, glial, and neural/neuroe...
BACKGROUND Hemangioblastomas are hypervascular lesions and hence their surgical management is challenging. In particular, if complete resection is to be attained, all feeding and draining vessels must be occluded. Although most intramedullary spinal cord tumors are treated utilizing a posterior approach, we describe an anterior surgical strategy for resection of an intramedullary cervical heman...
INTRODUCTION Hemangioblastomas are highly vascular tumors that can arise within the central nervous system as well as other organ systems within the body. They can arise sporadically or as part of von Hippel-Lindau syndrome. Those arising in critical locations within the central nervous system can be difficult to resect surgically and therefore pose a significant challenge and result in morbidi...
PURPOSE Receptor 7 (CXCR7) has recently been characterized as a novel receptor for CXCL12/SDF-1 (stromal cell derived factor-1). Given the demonstrated importance of CXCL12/SDF-1 in angiogenesis and tumour metastasis, we hypothesized that CXCR7 may also play a role in tumour pathogenesis. Located in the limited space of the intracranial cavity, any brain tumours can be inherently serious and li...
