n acetyl glucosamine/atrophy

OBJECTIVE The early stages of degenerative disc disease (DDD) primarily affect the disc nucleus pulposus (NP). Tissue-engineered strategies may enhance intervertebral disc (IVD) functionality. The aim of this study was to develop and evaluate a novel deacetylated poly-N-acetyl glucosamine (pGlcNAc)

UNASSIGNED Image-based early detection for diabetic retinopathy (DR) needs value addition due to lack of well-defined disease-specific quantitative imaging biomarkers (QIBs) for neuroretinal degeneration and spectropathological information at the systemic level. Retinal neurodegeneration is an early

In previous work (Herscovics et al., J. Biol. Chem., 269, 9864-9871), a novel mouse alpha-mannosidase cDNA was isolated by homology, taking advantage of identical regions between the amino acid sequences of the yeast and rabbit liver processing alpha 1,2-mannosidases of different specificities to

This study was undertaken to determine whether there are age-related changes in the specific activities of several glycosidases in fresh retinal pigment epithelial cells (RPE) isolated from the posterior pole of human donor eyes. One hundred and twenty-one pairs of eyes from human donors, between

Drusen are a feature of age-related macular degeneration (AMD). Lesions similar in appearance to drusen are also found in the fundi of patients with membranoproliferative glomerulonephritis type II (dense deposit disease, DDD). The lamina densa of the glomerular basement membrane, in DDD, is

A patient with early infantile neuronal ceroid-lipofuscinosis was examined by magnetic resonance imaging (MRI) and image-guided localized proton MR spectroscopy of brain using short-stimulated echo times. T2-weighted MRI revealed generalized cerebral atrophy and a reduction in signal intensity in

Post-mortem brain tissue was obtained from 28 patients with brain disorders, of which 15 had clinically diagnosed schizophrenia, 6 Alzheimer type dementia, 5 dementia with tangles and 2 cases of Down's syndrome. The controls were 22 cases from autopsies without brain disorders or with no known

The content of carbohydrate residues of both normal and phenobarbitale-halothane-hypoxia exposed rat liver has been examined by means of lectin histochemistry. Eight biotinylated lectins specific to galactose, N-acetyl-galactosamine, N-acetyl-glucosamine, fucose and mannose were applied to paraffin

Mouse (C3H) mucosal glycoconjugates were examined in normal small intestines and intestines infected with Echinostoma caproni or E. trivolvis using six different fluorescein-conjugated lectins: Triticum vulgaris agglutinin (WGA), Ulex europaeus agglutinin I (UEA-I), Ricinus communis agglutinin I

The binding patterns of gliadin and selected lectins to jejunal biopsy specimens obtained from children with total villous atrophy during active celiac disease (CD; 19 patients) and in remission (16 patients) were examined by light microscopy. Three categories of carbohydrate-specific lectins were

GNE myopathy is a rare, autosomal recessive, inborn error of sialic acid metabolism, caused by mutations in GNE, the gene encoding UDP-N-acetyl-glucosamine-2-epimerase/N-acetylmannosamine kinase. The disease manifests as an adult-onset myopathy characterized by progressive skeletal muscle weakness

Vascular endothelial growth factor 165 (VEGF165) is an important extracellular protein involved in pathological angiogenesis in diseases such as cancer, wet age-related macular degeneration (wet-AMD) and retinitis pigmentosa. VEGF165 exists in two different isoforms: the angiogenic VEGF165a, and the

It has been established for a long time that brain glucose metabolism is impaired in Alzheimer's disease. Recent studies have demonstrated that impaired brain glucose metabolism precedes the appearance of clinical symptoms, implying its active role in the development of Alzheimer's disease. However,
