Though faster brain ventricle enlargement is a marker for cognitive decline and the development of neurodegenerative diseases such as Alzheimer's, the effects of sleep on this marker have never been measured.
Specific topics include charge-selective claudin channels, dynamic properties of the tight junction barrier, the regulation of tight junction in human normal pancreatic duct epithelial cells and cancer cells, diverse types of junctions containing tight junction proteins in stratified mammalian epithelia, and the involvement of claudins in zebrafish brain ventricle morphogenesis.
Following third brain ventricle injection of cytomegalovirus (CMV)-green fluorescent protein or CMV-LUC gene constructs, we established that cells in the telencephalon and optic tectum are transfected.
1% fast green dye (Sigma) established that an injection of 4 [micro]L at an angle of approximately 45-50[degrees] relative to the top of the head and at a depth of 3-4 mm would partially fill the brain ventricle and expose cells in the forebrain and optic tectum to the injected solution.
These findings mean that, in the future, by using magnetic resonance imaging (MRI) to measure changes in brain ventricle size, we may be able to provide earlier and more definitive diagnosis," said Bartha, who is also an Associate Professor in the Schulich School of Medicine & Dentistry in Medical Biophysics.
He had to have a lumbar puncture as well as a shunt tube put into one of his brain ventricles to drain off more fluid.
Most sufferers also have hydrocephalus, a fluid that developed because of the spina bifida and which rests in brain ventricles.
The 2 lateral brain ventricles, their openings into the 3rd ventricle, aqueduct of the midbrain and the 4th ventricle, and the choroid plexus (resembling the fetal choroid membrane) lining these spaces.
However, he has now had his four-month ultrasound, and it was discovered that his frontal brain ventricles are enlarged.
Using antibodies against Mrp4 the investigators found that this protein is located in the brain's capillaries as well as in membranes of the choroid plexus -- the folds within the brain ventricles that make and release CSF.
Previous studies using MRI and computerized tomography have charted and enlargement of brain ventricles among a substantial portion of people with schizophrenia, but researchers disagree over the extent of the brain's shrinkage as well as the cause of the anatomical abnormalities.
Additionally, there was an eight to 10 percent increase in the size of the brain ventricles, which are areas filled with cerebrospinal fluid (CSF) that play a protective role in the brain.
