Introduction Tumor treating fields (TTFields) are low-intensity (1-3 v/m) intermediate frequency (200 khz for GBM) alternating fields that disrupt cell division. The treatment is increasingly used as a supplementary modality for patients with glioblastoma (GBM). Recent randomized clinical studies
Brain tumors are the first cause of cancer mortality in children and the 3rd cause in young adults. The most frequent brain tumors are gliomas and among them the most common type is astrocytoma. The most malignant astrocytoma is Glioblastoma (GBM). Standard therapy of newly diagnosed GBM patients
Primary brain tumors in adults are less common than metastatic tumors. The most frequent are glioblastoma multiforme, metastases, anaplastic astrocytoma, meningioma, pituitary tumors and vestibular schwannoma. 70% of the tumors in adults are supratentorial. The most infratentorial tumors are
Hepatocyte growth factor (HGF) is local acute phase protein with regenerative properties that become biologic inactive during chronic inflammation and loses the binding affinity to glycosaminoglycan in the extracellular ma-trix. HGF is excreted into the gastrointestinal tract and is not detected in

The exact mechanisms by which AMS develops remains poorly understood. Interestingly, brain and spinal cord swelling due to low oxygen levels can also occur in the period following surgery to treat thoracic and abdominal aortic aneurysms, dangerous swellings of the major blood vessel in the body.
Rationale: Current seasonal influenza vaccines mainly induce immune responses against viral membrane glycoproteins. These proteins, however, undergo continuous mutations by a process called antigenic drift. To prevent immune escape, annual vaccination with the latest predicted viral strains is
Fluid therapy is aimed to compensate for fasting which is required for surgery, to meet the ongoing fluid losses and to maintain electrolyte balance during surgery. Fluid deficit of a healthy child who is not fed parenterally may be estimated by multiplying hourly maintenance requirement for fluid
Study Procedures Once the subject has agreed to participate in the study and has signed the consent form, the baseline visit can be performed. A full medical history will be taken and a physical exam will be done as per local routine practice for an embolization procedure. The Cognard scale will be
Infrascanner is a portable device initially designed to detect intracranial hemorrhage in battlefield traumas. Infrascanner uses near infrared spectroscopy to measure cerebral blood flow non-invasively. This is achieved by putting the device against the scalp in 4 different areas (frontal, temporal,
BACKGROUND Radiation Necrosis: Stereotactic radiosurgery has become integral in treatment of brain tumors and arteriovenous malformations (AVM). In up to 10% of cases, this can lead to radiation necrosis (RN) with significant surrounding vasogenic edema and mass effect. Medical treatment for RN
Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a group of conditions characterised by prolonged but reversible multifocal narrowing of the cerebral arteries. It presents typically as acute severe headache, usually recurrent and thunderclap in character, with or without additional symptoms
Recent studies have shown that the ketogenic diet (high-fat, low-carbohydrate, and moderate protein; induce a shift from the primary metabolism of glucose to ketones) or Modified-Atkins diet may be effective in treating autism. Research on the Black and Tan BRachyury (BTBR) T+tf/J mouse strain,
Blood brain barrier:
The blood-brain barrier (BBB) is an intricate barricade composed of three distinct cell types: brain endothelial cells, pericytes, and astrocyte foot processes. While molecules that are small and lipophilic may easily traverse the BBB, large (> 180 Daltons) and/or hydrophilic
