1-hydroxypyrene

01/01/2014 - "In a group of patients with psoriasis (19), treated with Goeckerman regimen (GR), we evaluated their level of CN, level of chromosomal aberration in peripheral lymphocytes (CA), level of urinary 1-hydroxypyrene (1-OHP) and their value of Psoriasis Area and Severity Index (PASI). "
02/01/2010 - "We evaluated dermal absorption of PAHs as well as the mutagenic and genotoxic effects of GR in 16 children with psoriasis, by determining levels of 1-hydroxypyrene (1-OHP), 1-,2-,3-,4-hydroxyphenanthrene, (1-OHPhe, 2-OHPhe, 3-OHPhe, and 4-OHPhe), urinary mutagenicity (Salmonella mutagenicity assay, Ames test) and numbers of chromosomal aberrations in peripheral lymphocytes (CA), in urine and/or blood, before and after GR. "
04/01/2002 - "The aim of this study was to assess the cytogenetic effects of urban air pollution by analyzing the chromosomal aberration (CA) frequencies in lymphocytes and to estimate the polycyclic aromatic hydrocarbons (PAHs) exposure by measuring urinary 1-hydroxypyrene (1-OHP) levels. "
09/01/2012 - "The markers that fulfilled the inclusion criteria are: 1-hydroxypyrene, DNA adducts, chromosomal aberrations, micronuclei, oxidative damage to nucleobases, and methylation changes. "
03/01/2010 - "We evaluated dermal absorption of PAH as well as the genotoxic and apoptotic effects of GT in 20 patients with psoriasis, by determining numbers of chromosomal abnormalities in peripheral lymphocytes, and levels of 1-hydroxypyrene (1-OHP), p53 protein and soluble FasL (sFasL) in urine and/or blood, before and after GT. "

01/01/2021 - "Samples from participants who attended particleboard fires, showed no significant difference (p > 0.05) between 1-hydroxypyrene (1-OH-PYR) concentrations in urine pre- and post-burn. "
08/01/2008 - "Our objective was to evaluate the extent of firefighter exposure to particulate and PAHs during prescribed pile burns of mainly ponderosa pine slash and determine whether these exposures were correlated with changes in urinary 1-hydroxypyrene (1-HP), a PAH metabolite. "
01/01/2019 - "Methods: Using a repeated measures study design, we collected urine before, immediately after, and the morning after a work shift on prescribed burn and non-burn work days from 12 healthy subjects, and analyzed for malondialdehyde (MDA), 8-isoprostane, 1-hydroxypyrene (OH-pyrene), and mutagenicity in Salmonella YG1041 +S9. "

01/01/2018 - "After adjusted for covariates, each 1-unit-increase in natural log-transformed concentrations of 2-hydroxyfluorene (2-OHFLU), 4- hydroxyphenanthrene (4-OHPHE), 1-OHPHE, 2-OHPHE, 1-Hydroxypyrene (1-OHPYR) and ∑OH-PAHs were significantly associated with elevated risk of adult asthma with odds ratios of 2.04, 2.38, 2.04, 1.26, 2.35 and 1.34, respectively. "
12/01/2016 - "Conversely, urinary 1-hydroxyphenanthrene, 3-hydroxyphenanthrene, 1-hydroxypyrene, and 4-hydroxyphenanthrene were inversely associated with asthma and infections. "
10/01/2023 - "The current study aims to explore the effects of nine urine monohydroxy PAH metabolites (OHPAH) including 1-hydroxynaphthalene (1-OHNAP), 2-hydroxynaphthalene (2-OHNAP), 3-hydroxyfluorene (3-OHFLU), 9-hydroxyfluorene (9-OHFLU), 1-hydroxyphenanthrene (1-OHPHE), 2-hydroxyphenanthrene (2-OHPHE), 3-hydroxyphenanthrene (3-OHPHE), and 1-hydroxypyrene (1-OHPYR) on current asthma in people in the United States using a variety of statistical techniques. "

09/01/2014 - "Urinary 1-hydroxypyrene is associated with oxidative stress and inflammatory biomarkers in acute Myocardial Infarction."
09/01/2014 - "Considering that 1-hydroxypyrene (1-OHP) is the major biomarker of exposure to pyrenes, the purpose of this study was to evaluate the potential association between 1-OHP and oxidative stress/inflammatory biomarkers in patients who had suffered an acute myocardial infarction (AMI). "
11/01/2015 - "In particular, urinary 4-hydroxyphenanthrene was associated with hypertension (odds ratio (OR) 1.33, 95% confidence interval (CI) 1.00-1.76, P = 0.048, PAR 5.1%), urinary 1-hydroxypyrene was significantly associated with heart attack (OR 1.47, 95%CI 1.05-2.06, P = 0.027, PAR 1.7%), and urinary 2-hydroxynapthalene (2-naphthol) was associated with cancer (OR 1.46, 95%CI 1.12-1.90, P = 0.008, PAR 3.9%). "

08/01/2013 - "Elevated levels of 1-hydroxypyrene and N'-nitrosonornicotine in smokers with head and neck cancer: A matched control study."
08/01/2015 - "Eighty-four cigarette smokers with head and neck cancer completed tobacco and alcohol use questionnaires, and the following urinary tobacco metabolites were quantified: 1-hydroxypyrene (1-HOP), N'-nitrosonornicotine and its glucuronides (total NNN), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and its glucuronides (total NNAL), and cotinine.
