BACKGROUND: Glioblastoma (GBM) is the most aggressive and common brain tumor in adults, currently lacking effective life-prolonging and recurrence-preventing therapy; median survival of GBM patients stands at only 14-16 months. Increasing lines of evidence indicate that Anaplastic lymphoma kinase (ALK), a druggable tyrosine kinase receptor over-expressed in GBM, represents a potential therapeutic target in this tumor. OBJECTIVE: An overview of the state of the art and the existing recent patents regarding potential exploitation of ALK as a therapeutic target and/or diagnostic/prognostic factor in GBM...

Cerebral ischemia causes severe brain injury and results in selective neuronal death through programmed cell death mechanisms, including apoptosis and autophagy. Minimizing neuronal injury has been considered a hot topic among clinicians. The present study elucidated the effect of thymosin β4 (Tβ4) on neuronal death induced by cerebral ischemia/reperfusion in PC12 cells that were subjected to oxygen‑glucose deprivation and reoxygenation (OGD/R). The survival, apoptotic and autophagy rates of PC12 cells were investigated...

Primary central nervous system lymphomas (PCNSLs) are mature B-cell lymphomas confined to the central nervous system (CNS). Blood-brain barrier (BBB) dysfunction drastically alters the cerebrospinal fluid (CSF) proteome in PCNSL patients. To reveal the interaction of PCNSL tumors with CNS structures and the vasculature, we conducted a whole-proteome analysis of CSF from PCNSL patients (n = 17 at initial diagnosis) and tumor-free controls (n = 10) using label-free quantitative mass spectrometry. We identified 601 proteins in the CSF proteome using a one-step approach without further prefractionation, and quantified 438 proteins in detail using the Hi-N method...

To investigate alleviative effect of selenium (Se) on lead (Pb)-induced apoptosis in chicken nervous tissues, 7-day-old chickens were randomly divided into four groups. The control group was fed a standard diet and drinking water. In the Pb and Se/Pb groups, (CH3OO)2Pb was dissolved in drinking water. In the Se and Se/Pb groups, Na2SeO3 was put into the standard diet. Embryonic neurocytes were divided into the control, Se (containing Na2SeO3), Pb (containing (CH3COO)2Pb), and Se/Pb (containing Na2SeO3 and (CH3COO)2Pb) groups...

The standard treatment for primary central nervous system (CNS) lymphoma is based on chemotherapy. However, there are patients who are not indicated for chemotherapy and when left untreated, the expected functional outcomes for these patients are devastating since the disease causes various neurologic symptoms. Therefore, we assessed the effects of radiotherapy as an alternative therapy in primary CNS lymphoma. Thirty-two patients were diagnosed with primary CNS lymphoma and treated with radiotherapy alone...

Intravascular lymphoma (IVL) is a rare disease characterized by the proliferation of lymphoma cells in the lumen of the small blood vessels. Although early diagnosis of IVL is important to prolong survival of the patients, its atypical symptoms and clinical course often delay its diagnosis. More than half of the patients are diagnosed at autopsy. We report a 68-year-old man who presented with transient ideomotor apraxia and mildly elevated soluble interleukin-2 receptor levels. He was initially diagnosed with aortogenic embolic stroke...

Several studies have examined neonatal diabetes, a rare disease characterized by hyperglycemia and low insulin levels that is usually diagnosed in the first 6 month of life. Recently, the effects of diabetes on the brain have received considerable attention. In addition, hyperglycemia may perturb brain function and might be associated with neuronal death in adult rats. However, few studies have investigated the damaging effects of neonatal hyperglycemia on the rat brain during central nervous system (CNS) development, particularly the mechanisms involved in the disease...

Intravascular lymphoma (IVL) has been characterized in many case reports by multiple white matter lesions reflecting ischemic changes. In contrast, there are very few case reports of cerebral or cerebellar hemorrhage resulting from IVL. A 56-year-old woman was referred to our department with two-week history of headache, nausea, and poor appetite. Gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) showed dilated veins on the cerebellar surface. No ischemic lesions were detected on diffusion-weighted images...
