The expression of heparan sulfate proteoglycans (HSPGs) by human glioma cells was examined by biochemical and immunological methods in vitro and in vivo. Chondroitin sulfate was shown to represent the major [3H]glucosamine-labeled glycosaminoglycan synthesized by cultured normal brain cells. However, high-grade glioma-derived cells were shown to express significantly increased quantities of hya...

The co-occurrence of a vestibular schwannoma and a low-grade glioma is rare, and even rarer is the association with an oligodendroglioma. Although various authors have addressed the problem of treating patients with incidentally discovered indolent low-grade gliomas, an established protocol does not exist to date. The common approach is to reserve surgery until there is radiological evidence of...

Protease inhibitors regulate a variety of physiological and pathological processes including angiogenesis, embryo implantation, intravascular fibrinolysis, wound healing, and tumor invasion. Tissue factor pathway inhibitor (TFPI) 2 is a Mr 32,000 Kunitz-type serine protease inhibitor that inhibits plasmin, trypsin, chymotrypsin, cathepsin G, and plasma kallikrein but not urokinase-type plasmino...

Correspondence to: Professor Ian R Whittle, Department of Clinical Neuroscience, Western General Hospital, Crewe Road, Edinburgh EH4 2XU, UK; [email protected] _________________________ T he management of low grade glioma is one of the most controversial areas in clinical neurooncology. There are numerous reviews and editorials outlining the difficulties in management of these lesions. Ind...

Collectively, pediatric low-grade gliomas account for most brain tumors reported in children. Surgery is typically curable for operable lesions. However, more effective therapies are required for inaccessible tumors, both to overcome refractory disease and to minimize the toxicity associated with conventional adjuvant chemotherapy and radiotherapy regimens. Recent years have witnessed rapid imp...

OBJECTIVE This work intends to quantitatively analyze on pathological grade of glioma using Magnetic Resonance (MR) diffusion weighted imaging (DWI) and exploring the relativity of pathological grade and Apparent Diffusion Coefficient (ADC) value of MR diffusion weighted imaging. PATIENTS AND METHODS 40 patients with glioma accepted the MR diffusion weighted imaging to measure the ADC value o...

Gross total resection (GTR) of glioma is critical for improving the survival rate of glioma patients. One of the greatest challenges for achieving GTR is the difficulty in discriminating low grade tumor or peritumor regions that have an intact blood brain barrier (BBB) from normal brain tissues and delineating glioma margins during surgery. Here we present a highly sensitive, label-free teraher...

The clinical value of MR diffusion tensor imaging (DTI) in grade diagnosis of gliomas was investigated. A total of 31 patients with glioma were administered 3.0T MR convention and DTI examination, with quantitative measurement of anisotropy coefficient fractional anisotropy (FA) and apparent dispersion coefficient (ADC) value, and the comparison of quantitative parameters of glioma between low-...
