Stem cells generate neurons in discrete regions in the postnatal mammalian brain. However, the extent of neurogenesis in the adult human brain has been difficult to establish. We have taken advantage of the integration of (14)C, generated by nuclear bomb tests during the Cold War, in DNA to establish the age of neurons in the major areas of the human cerebral neocortex. Together with the analys...
tention in a series of 12 patients, according to Sodee, and he discontinued the mercuhydrin injection ( 7 ). McAfee noted that pharmacologists have been unable to block the uptake in the kidneys, despite pre-dosing rats with cold mercurials with doses up to 20 mg of mercury per kilogram, a tremendously toxic dose (8). Although brain scanning with such short-lived isotopes as 99mTcand 197Hg is r...
We describe a meta-analytic method that tests for the difference between two groups of functional neuroimaging experiments. We use kernel density estimation in three-dimensional brain space to convert points representing focal brain activations into a voxel-based representation. We find the maximum in the subtraction between two probability densities and compare its value against a resampling d...
The head warming in hypothermic victims is an alternative way of heat donation, which does not inhibit shivering and does not impede the access to the patient's chest. It seems to be a safe method in mild hypothermia. The authors of the review article "Accidental hypothermia - an update" suggest this way of heat donation, without indicating precisely, in which group of patients it can be applie...
Intact brain and brain homogenates readily form free fatty acids and ceramides, even in the cold during subcellular isolation procedures. The fatty acid formation is slightly stimulated by chelators and might be due to phospholipid hydrolysis by lysosomal phospholipases. The ceramide formation is accompanied by loss of sphingomyelin and is apparently due to the action of neutral, metal ion-acti...
Background Methylphenidate (MPH) is commonly prescribed for children who have been diagnosed with attention deficit hyperactivity disorder (ADHD); however, the action mechanisms of methylphenidate have not been fully elucidated. Studies have shown a relationship between apoptosis signaling pathways and psychiatric disorders, as well as therapeutic targets for such disorders. So, we examined the...
