Glioblastoma is the most common and lethal primary brain tumor. Tumor initiation and recurrence are likely caused by a sub-population of glioblastoma stem cells, which may derive from mutated neural stem and precursor cells. Since CD133 is a stem cell marker for both normal brain and glioblastoma, and to better understand glioblastoma formation and recurrence, we looked for dys-regulated microR...

BACKGROUND AND PURPOSE Our purpose was to test a new variant of the fluid-attenuated inversion-recovery (FLAIR) sequence that was designed to reduce CSF and blood flow artifacts by use of a non-slice-selective inversion pulse and k-space reordered by inversion time at each slice position (KRISP). METHODS With the KRISP FLAIR sequence, the slice order was cycled so that each inversion time (TI...

syringobulbiais very rare condition defined as slit-like fluid cavity in the brain stem. several conditions have been reported to be associated with syringobulbia including neoplasms, spinal cord traumas or lesions such as tethered cord, hind-brain herniation, infections such as meningitis and in isolation.although post-traumatic syringomyelia has been wieldy described previously, traumatic bra...

extract  although there are new ways to portray the brain, colored and computerized encephalography but coma is still unknown and such as death remain beyond comprehension and knowing. is not it ?   perhaps because of this, despite knowing that some part of the brain is not yet fully understood all its parts. but knowing the components that working to each other is key for discovering a lot of ...

Neural stem/precursor cells (NPCs) are a promising stem cell source for transplantation approaches aiming at brain repair or restoration in regenerative neurology. This directive has arisen from the extensive evidence that brain repair is achieved after focal or systemic NPC transplantation in several preclinical models of neurological diseases. These experimental data have identified the cell ...

Introduction: Appropriate thyroid hormone (TH) levels are essential during the critical period of brain development, which is associated with the growth of axons and dendrites and synapse formation. In rats, oral motor circuits begin to reach to their adult pattern around 3 weeks after birth, the period in which alteration from sucking to biting and chewing occurs (weaning time). Trigeminal ...

Two cases of brain stem stroke involving the upper pons and the ponto-mesencephalic junction presented with transient excessive pathological yawning, associated with gait ataxia and in one subject with upper limb and facial hemiparesis. A causal relation is hypothesised between the brain stem lesion and pathological yawning, possibly related to denervation hypersensitivity of a putative brain s...

Three cases are presented which depict the spectrum of neurological disability attendant on intra-axial brain-stem metastases, ranging from fulminant decline to a more leisurely and less disabling course. The rarity of primary glioma of brain-stem compared with brain-stem metastases in a general hospital population in the age group from 50 years and over is emphasized. Clinical deficit, certai...

The assessment of brain stem function in comatose patients is now regular medical practice world wide. When envisaging a diagnosis of brain stem death it is essential, firstly, to establish that the patient is suffering from irremediable structural brain damage of known cause, and, secondly, to exclude the primary or contributory role of reversible causes of apnoeic coma with absent brain stem ...
