A panel of 14 lectins was used to investigate the expression of saccharides by cerebral microvessels (MBV) in ageing, Alzheimer's disease (AD) and Down's syndrome (DS). Broad increases in lectin binding with age may reflect changes in amount and diversity of glycoproteins due to the thickening of the basement membrane (BM) common in older persons. In AD,(More)
The amount of myelin in the outer band of Baillarger in the human visual cortex stained by Luxol Fast Blue MBS, has been measured in normal individuals of wide age range, in a group of blind and severely visually impaired but otherwise normal individuals and in a series of demented patients of the Alzheimer and multi-infarct type who were apparently(More)
BACKGROUND The ability to perform de novo biosynthesis of purines is present in organisms in all three domains of life, reflecting the essentiality of these molecules to life. Although the pathway is quite similar in eukaryotes and bacteria, the archaeal pathway is more variable. A careful manual curation of genes in this pathway demonstrates the value of(More)
The presence of numerous senile plaques (SP) and neurofibrillary tangles (NFT) within association areas of the neocortex and within the hippocampus and amygdala, is generally regarded as providing the histopathological hallmarks of Alzheimer's disease (AD) (Mann, 1985). Similar pathological changes, to those of AD, are seen in the brains of nearly all(More)
High performance computing (HPC) is essential in order to perform detailed MD simulations that allow for mechanistic insight into many diseases. Alzheimer's disease (AD) pathology is primarily caused by the Aβ(42) peptide. MD simulations of a toxic (human Aβ(42)) and non-toxic (rat Aβ(42)) were performed in physiologically-relevant membrane(More)
The periodic acid Schiff reaction was applied to neurones in the Lateral Geniculate Body (L.G.B.) of a series of normal and blind patients over a wide age range. The quantity of the reaction product was determined as a measure of lipofuscin which was found to increase linearly with age in the L.G.B. neurones. The amount in the neurones of the blind patients(More)
