Vascular endothelial growth factor (VEGF) has been found to be involved in vasculogenesis in different intracranial lesions. We investigated meningeal cellularity and VEGF expression in dura mater of patients with and without moyamoya disease. Nine dural specimens from nine cerebral hemispheres of seven patients with moyamoya disease and four control dural(More)
OBJECTIVE To evaluate the role of the apparent diffusion coefficient (ADC) using periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) diffusion weighted imaging (DWI) in the differentiation between sellar and parasellar mass lesions. MATERIALS AND METHODS The study protocol was approved by our institutional review(More)
BACKGROUND Geminin is a nuclear protein that belongs to the DNA replication inhibitor group. It inhibits DNA replication by preventing Cdt1 from loading minichromosome maintenance protein onto chromatin, as is required for DNA replication. For this study, the authors investigated geminin expression in high-grade astrocytic tumors, including anaplastic(More)
Secondary brain tumors rarely arise after cranial irradiation; among them, meningiomas and glioblastomas are the most common and secondary oligodendroglial tumors the most rare. We present a 48-year-old man who developed an oligodendroglial tumor 38 years after receiving 50 Gy of cranial irradiation to a pineal tumor. He underwent gross total removal of a(More)
BACKGROUND The function of the cyclin-dependent kinase (cdk) inhibitor p27 is regulated by translocation between the nucleus (activate) and the cytosol (inactivate). No previous reports have examined the subcellular localization of p27 in glioma which was evaluated here regarding the prognosis in high-grade astrocytomas. PATIENTS AND METHODS The pattern(More)
A 35-year-old man presented with penetrating spinal injury after attempting suicide by stabbing a wooden chopstick into his mouth. The object penetrated the pharynx, and the tip entered the spinal canal of the atlantoaxial vertebrae. Emergent surgery disclosed that the tip of the chopstick had penetrated between the dural sac and the vertebral artery. There(More)
It has already been proved by many studies that surgical revascularization definitely helps in curing the symptoms of moyamoya vasculopathy. In this regard, we present a case of moyamoya disease which was cured by concurrent multiple anastomotic procedures, namely superficial temporal artery (STA), middle cerebral artery (MCA) anastomosis,(More)
Free floating thrombus in the carotid artery is a well-known phenomenon, though relatively rare. We present a case in which we performed open surgery and achieved successful retrieval of the thrombus. A 40 year-old male patient presented with ischemic stroke and mild left hemiparesis. Computerized tomography and magnetic resonance imaging showed infarction(More)
Intrathecal baclofen (ITB) has been found to be helpful not only for spasticity but also for unconsciousness in a vegetative patient. This is the first case of ITB in Nepal, and here we discuss the effectiveness of ITB for spasticity in a patient in vegetative state. We also discuss about a simple technique for ITB used in Nepal where baclofen pump is not(More)
At present, few organisms are known to and capable of naturally producing laccases and white rot fungi are one such group. In the present study, three fungal species, namely, Ganoderma lucidum-CDBT1, Ganoderma japonicum, and Lentinula edodes, isolated from their native habitat in Nepal were screened for laccase production, and G. lucidum-CDBT1 was found to(More)
