Sodium-dependent glutamate binding was studied as a possible index of the integrity of glutamate/aspartate (Glu/Asp) nerve endings in seven cortical areas from postmortem brains of 15 persons with senile dementia of the Alzheimer type (SD), 10 controls matched for age, sex and postmortem delay (PMD), and single cases of Down's syndrome and(More)
Five hours after the stereotaxic injection of approximately 1 ng of [125I]basic fibroblast growth factor (bFGF) into rat substantia nigra (SN), small but consistent amounts of radioactivity were found in the ipsilateral striatum (CP). None was found in the ipsilateral thalamus or contralateral CP, SN or thalamus. The amount found in the ipsilateral CP was(More)
Intraperitoneal injection of 5 mg/kg of tetrahydro-9-amino-acridine (THA) in rats 1 h before intrastriatal injection of 50-150 nmol of quinolinic acid potentiated the local neurotoxicity as indicated by measurements of striatal levels of glutamate decarboxylase and choline acetyltransferase. A larger dose (10 mg/kg) THA had no significant effect. The(More)
Peripheral-type benzodiazepine binding of [3H]Ro5-4864 at one, non-saturating concentration and activities of choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) were measured in 7 cortical areas from postmortem brains of 18 patients with Alzheimer disease (AD), 12 age-matched controls, and 15 miscellaneous neurological cases. None of the(More)
Based on a suspected pathological relationship of autoimmunity in Alzheimer's disease (AD), antibodies to myelin basic protein (MBP) were investigated in the sera of AD patients, healthy controls and disease controls. As detected by the protein-immunoblotting technique at a screening serum dilution of 1:400, sera from 16 of 18 (89%) AD patients were(More)
Spillover of lipoprotein lipase-generated fatty acids from chylomicrons into the plasma free fatty acid (FFA) pool is an important source of FFA and reflects inefficiency in dietary fat storage. We measured spillover in 13 people with type 2 diabetes using infusions of a [(3)H]triolein-labeled lipid emulsion and [U-(13)C]oleate during continuous feeding,(More)
gamma-Glutamyltransferase (EC 2.3.2.2; gamma-GT) may be important in the transport of amino acids or peptides across the blood-brain barrier. Gamma-GT activities were the same in cortical samples from Alzheimer and age-matched control brains, and there was no correlation between gamma-GT and choline acetyltransferase (ChAT) or acetylcholinesterase (AChE)(More)
