98 Possible Causes for nitrophenols

  • Nitrobenzene Poisoning

    P-aminophenol and p-nitrophenol were excreted in the urine with a coefficient of 0.008 hr -1 . The ratio of excreted p-nitrophenol to p-aminophenol was 2:1.[link.springer.com] At level of nitrophenol and p-aminophenol [3, 21, 24].10-15% of methemoglobin, person is usuallyasymptomatic with mild cyanotic changes.[pubhtml5.com] Nitrobenzene is metabolized in the body nitrophenol and aminophenol and later on excreted in urine (up to 65%), and in stools (up to 15%) after five days of ingestion.[documents.tips]

  • Parathion Poisoning

    Methyl parathion and the major metabolite 4-nitrophenol where measured in serum and urine.[ncbi.nlm.nih.gov] Plasma obidoxime concentrations were followed as well as the cumulative urinary para-nitrophenol conjugate excretion as a measure of total poison load.[ncbi.nlm.nih.gov]

  • Dinitrophenol

    […] was frequently used to symbolize change and transitions, such as the progression from past to future or from one viewpoint to another. 2,4-dinitrophenol (DNP) and other nitrophenols[ncbi.nlm.nih.gov] Further studies in laboratory animals with nitrophenolic compounds are required for clarification of their testicular toxicity and for risk assessment in humans.[ncbi.nlm.nih.gov]

  • Alpha-Galactosidase

    The assay is based on a 15-minute hydrolysis of p-nitrophenyl-a-D-galactopyranoside followed by spectrophotometric measurement of the liberated 4-nitrophenol.[enzymeeducationinstitute.com] One Galactosidase Unit is the defined as the quantity of enzyme that will liberate 1 μmol/min of p-nitrophenol under the conditions of the assay.[globalhealingcenter.com] Activity: One FCC Galactosidase activity unit (GalU) is defined as the quantity of enzyme that will liberate p-nitrophenol at the rate of 1 μmol/ minute under the conditions[enzymeeducationinstitute.com]

  • Pseudomonas

  • Lysosomal Acid Phosphatase Deficiency

    The lysosomal fraction of homogenates of cultivated fibroblasts from both parents (first cousins) had acid phosphatase levels of 3.0 0.9 μmoles of p-nitrophenol phosphate[nejm.org]

  • Pseudomonas Aeruginosa

    It can use PNP, succinate, phenol and acetamide as C sources but not m-nitrophenol, o-nitrophenol and other higher nitrophenols.[scialert.net] To our knowledge this is the first report of a Pseudomonas aeruginosa strain able to degrade p-nitrophenol (PNP).[scialert.net] Growth kinetics of the 4-nitrophenol degrading strain Pseudomonas putida PNP1. Acta Biotechnol., 18: 29-41.[scialert.net]

  • Polyarticular Juvenile Idiopathic Arthritis

    Low levels of AP activity was observed in pJIA cultures compared with CT cultures (67.16 /- 53.35 vs 100.11 /- 50.64 mumol p-nitrophenol/h(-1) mg(-1) protein, P 0.008).[ncbi.nlm.nih.gov]

  • Wolman Disease

    Cells from patient 1 had 5% of control levels of acid lipase, using 14C-triolein as substrate; however, when artificial substrates (esters of 4-methylumbelliferone and p-nitrophenol[ncbi.nlm.nih.gov]
