Soil enzymatic activity and wheat grain yield under cover crop systems

open access: yesPesquisa Agropecuária Tropical, 2023
For years, the impacts of using cover crops in productive systems have been measured by their relation with soil chemical and physical characteristics. Consequently, the effects on the soil microbiological characteristics have been little explored.

A patient presenting a 22q13 deletion associated with an apparently balanced translocation t(16;22): an illustrative case in the investigation of patients with low ARSA activity

open access: yesGenetics and Molecular Biology, 2012
A 10-year-old speechless, mentally deficient male, with low arylsulfatase A (ARSA) activity, and presumably, methachromatic leukodystrophy, underwent genetic evaluation.

Characterization of iodothyronine sulfatase activities in human and rat liver and placenta [PDF]

open access: yes, 2002
In conditions associated with high serum iodothyronine sulfate concentrations, e.g. during fetal development, desulfation of these conjugates may be important in the regulation of thyroid hormone homeostasis. However, little is known

Mucopolysaccharidosis type VI phenotypes-genotypes and antibody response to galsulfase [PDF]

open access: yes, 2013
Background: Mucopolysaccharidosis type VI (Maroteaux-Lamy syndrome; MPS VI) is an autosomal recessive lysosomal storage disorder in which deficiency of N-acetylgalactosamine 4-sulfatase (arylsulfatase B; ARSB) leads to the storage of glycosaminoglycans ...

Glycosylation and phosphorylation of arylsulfatase A.

open access: yesJournal of Biological Chemistry, 1994
The glycosylation and phosphorylation of the lysosomal enzyme arylsulfatase A was analyzed by a combination of metabolic labeling, tryptic fragmentation, mass spectrometry, and radiosequencing. The results demonstrate that all three potential N-glycosylation sites at Asn residues 158, 184, and 350 are utilized in arylsufatase A and carry high mannose ...

Dysfunction of Platelet-derived Growth Factor Receptor α (PDGFRα) Represses the Production of Oligodendrocytes from Arylsulfatase A-deficient Multipotential Neural Precursor Cells*

open access: yesJournal of Biological Chemistry, 2015
Background: PDGFRα is a key signaling component in oligodendrogenesis. Results: Multipotential Neural precursors (NPs) deficient in arylsulfatase A (ASA) show a higher ratio of long versus short fatty acid sulfatides, reduction in PDGFRα, decreased AKT ...

Relative Frequency of Metachromatic Leukodystrophy in Egypt: A Reference Laboratory Report

open access: yesFrontiers in Bioscience-Scholar
Background: Metachromatic leukodystrophy (MLD) is an autosomal recessive hereditary neurodegenerative disease caused by a deficiency in arylsulfatase A (ARSA) activity and belongs to the group of lysosomal storage diseases.
