CsF is commonly used for such reactions. Solutions of caesium fluoride in THF or DMF attack a wide variety of organosilicon compounds to produce an organosilicon fluoride and a carbanion, which can then react with electrophiles, for example: [10]
Artificial cerebrospinal fluid (aCSF) is a buffer solution prepared with a composition representative of cerebrospinal fluid that is used experimentally to immerse isolated brains, brain slices, or exposed brain regions to supply oxygen, maintain osmolarity, and to buffer pH at biological levels.
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialized ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations .
Any CSF leak is most often characterized by orthostatic headaches, which worsen when standing, and improve when lying down. Other symptoms can include neck pain or stiffness, nausea, vomiting, dizziness, fatigue, and a metallic taste in the mouth. A CT myelography scan can identify the site of a cerebrospinal fluid leakage.
Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]
One drop of CSF sample (collected from the patient by lumbar puncture technique), is added to about 1ml of Pandy's solution. The turbid appearance signifies the presence of elevated levels of globulin protein in the CSF and is regarded as positive Pandy's reaction.
Cerebrospinal fluid, clear colorless bodily fluid found in the brain and spine; Colony-stimulating factor, secreted glycoproteins Macrophage colony-stimulating factor, "CSF-1" Granulocyte-macrophage colony-stimulating factor, "CSF-2" Granulocyte colony-stimulating factor, "CSF-3" Cancer slope factor, estimate the risk of cancer
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
