We have investigated the relationship of plaque dystrophic neurites expressing beta-amyloid precursor protein (beta APP) to those bearing markers of neurofibrillary degeneration (tau), or accumulating the synaptic protein chromogranin A (CgA). In cortical and hippocampal plaques in Alzheimer's disease (AD) beta APP colocalized with CgA in a neuritic(More)
Hirano bodies (HB) are cytoplasmic inclusions predominantly found in the CA1 sector of the hippocampus. In Alzheimer's disease they are dislocated to the stratum pyramidale from their normal position in the stratum lacunosum. Hirano bodies are known to contain epitopes related to microfilaments (actin), neurofilaments, and microtubules (tau). In cryostat(More)
Abnormal (dystrophic) neurites are widespread in the brains of patients with Alzheimer's disease (AD). Subsets of these neurites cluster in intimate association with amyloid deposits, constituting classic senile plaques. Two major markers expressed by many plaque-associated neurites are the microtubule associated protein tau and chromogranin A, a soluble(More)
The purpose of this study was to investigate the effect of sucrose-glycine excipient systems on the stability of selected model proteins during lyophilization. Recovery of protein activity after freeze-drying was examined for the model proteins lactate dehydrogenase and glucose 6-phosphate dehydrogenase in a sucrose-glycine-based excipient system in which(More)
One important method to obtain the continuous surfaces of soil properties from point samples is spatial interpolation. In this paper, we propose a method that combines ensemble learning with ancillary environmental information for improved interpolation of soil properties (hereafter, EL-SP). First, we calculated the trend value for soil potassium contents(More)
Associations between metabolic syndrome (MetS) and osteoporotic fracture have been reported. However, the epidemiological studies are not conclusive. The objective of the study was to determine whether MetS associates with osteoporotic fracture. This was a cross-sectional study of 9,930 Chinese adults aged 40 years or older in the Chongming District,(More)
The changes in chromogranin A expression in the human striate cortex from birth till 67 years were studied by immunohistochemical method in 18 autopsied patients. The first chromogranin A immunoreactivity (CgA ir) was identified at birth in layer IV (especially IVc) mainly as fine nerve terminals. By 6 months, the first perikaryal reactivity was noted in(More)
