beta glucuronidase/atrophy

An 18-year-old boy showed childhood onset of mental retardation, neurogenic muscle atrophy with hyperreflexia, Marfan-like features, multiple epiphyseal dysplasia, increased urinary excretion of dermatan sulfate, and decreased lysosomal enzyme activities in beta-galactosidase, beta-glucuronidase,

Mucopolysaccharidosis type VII (MPS VII) is a lysosomal storage disease caused by beta-glucuronidase (GUSB) deficiency. This disease exhibits a broad spectrum of clinical signs including skeletal dysplasia, retinal degeneration, cognitive deficits and hearing impairment. Sustained, high-level

Childhood-onset proximal spinal muscular atrophy (SMA) is a heritable neurological disorder, which has been mapped by genetic linkage analysis to chromosome 5q13, in the interval between markers D5S435 and D5S557. Here, we present gene sequences that have been isolated from this interval, several of

Degeneration processes that affect bioprosthetic heart valves made from glutaraldehyde treated bovine pericardium are poorly understood. The present study undertook the identification and characterization of matrix metalloproteinases (MMPs) in extracts obtained from 28 pericardial derived

Paralogous regions are duplicated segments of chromosomal DNA that have been acquired during the evolution of the genome. Subsequent divergent evolution of the genes within paralogous regions can lead to the formation of gene families. Here, we report the identification of a region on Chromosome

YACs from the region containing the spinal muscular atrophy (SMA) locus at 5q12 have been used as probes in a direct screening of cDNA libraries to isolate 8 cDNAs, mapped to different YAC fragments. Three clones showed complete identity to the genes for cyclin B1 (CCNB1), the p44 subunit of the

OBJECTIVE To investigate the changes in insulin-like growth factor-1 (IGF-1) expression levels in the degenerative mandibular condylar cartilage. METHODS Thirty-six rats were divided into the unilateral anterior crossbite and control groups. The expression levels of IGF-1; IGF-1 receptor (IGF-1R);

Retinoic acid (0.5% in acetone) was applied topically to the back skin of five juvenile rhesus monkeys once a day for 7 successive days. Two control animals were given vehicle alone. Skin specimens were taken from each animal at 0, 1, 2, and 4 weeks. The tissues were prepared for both histology

The effects of systemic infusion of purified beta glucuronidase, lactic acid and a combination of these were studied in normal dogs from the viewpoints of hemodynamics and blood coagulation. In none of the groups was an obvious deterioration in arterial blood pressure, pulse rate, central venous

Daily administration of 2g/kg/day di(2-ethylhexyl)phthalate (DEHP) to immature rats was found to cause testicular atrophy and reduce zinc concentration. Specific activities of testicular enzymes associated with postmeiotic spermatogenic cells, such as lactate dehydrogenase isozyme-X, hyaluronidase

The motor neuron degeneration (Mnd) mutation in the mouse is a late onset, autosomal dominant, neurodegenerative disease in which ventral horn neurons have been shown to contain numerous, large cytoplasmic inclusions. Histochemical and immunocytochemical studies performed on spinal cord from Mnd/Mnd

The rabbit corneal endothelium phagocytized polystyrene spheres 0.5 micron in diameter. After phagocytizing spheres, the endothelium degenerated, and lost from the Descemet's membrane. Lysosomal enzyme activities of the endothelium-Descemet's membrane complex, such as acid phosphatase,
