BACKGROUND The purpose of this study was to assess the feasibility of conducting biological tetrachloroethylene (perchloroethylene, PCE) exposure assessments of dry cleaning employees in conjunction with evaluation of possible PCE health effects. METHODS Eighteen women from four dry cleaning facilities in southwestern Ohio were monitored in a pilot study of workers with PCE exposure. Personal...

OBJECTIVE To examine whether prenatal cocaine exposure (PCE) predicts externalizing problems in late childhood. METHODS Externalizing problems were assessed using caregiver, teacher, and child ratings and a laboratory task when children (N = 179; 74 cocaine exposed) were aged 8-10 years. PCE, environmental risk, sex, neonatal health, other prenatal exposures, and foster care history were exam...

Few empirical studies in the UK have examined the complex social patterns and values behind quantitative estimates of the prevalence of pharmacological cognitive enhancement (PCE). We conducted a qualitative investigation of the social dynamics and moral attitudes that shape PCE practices among university students in two major metropolitan areas in the UK. Our thematic analysis of eight focus g...

matched unexposed controls. The results showed a A recent study demonstrates that dry-cleaners chronicsignificant increase in a number of parameters (urinary ally exposed to perchloroethylene (PCE) show clear excretion of proteins, laminin fragments, glycosaminoevidence for renal damage [1]. PCE is a synthetic glycan, and tubular epithelial brush-border antigen) halogenated hydrocarbon. It is u...

We ask why pharmacological cognitive enhancement (PCE) is generally deemed morally unacceptable by lay people. Our approach to this question has two core elements. First, we employ an interdisciplinary perspective, using philosophical rationales as base for generating psychological models. Second, by testing these models we investigate how different normative judgments on PCE are related to eac...

BACKGROUND AND PURPOSE The reported incidence of PCE during PV varies, depending on the sensitivity of diagnostic tests used. To assess the true incidence of PCE, we performed native chest CT during follow-up in a large proportion of patients from the VERTOS II trial. MATERIALS AND METHODS VERTOS II is a prospective multicenter randomized controlled trial comparing PV with conservative therap...

Objective: Ionizing radiation produces free radicals which induce DNA damage and cell death. Origanum vulgare leaf extract (OVLE) is a natural compound and its capability of scavenging free radicals and its antioxidant activity have been demonstrated by many researchers. In this study, using micronucleus assay, radioprotective effect of OVLE against clastogenic and cytotoxic effect of gamma irr...

Prenatal cocaine exposure (PCE) may increase adolescent substance use through alterations of neurotransmitter systems affecting fetal brain development. The relationship between PCE and substance use at 15 and 17 years was examined. Subjects (365: 186 PCE; 179 non-cocaine exposed (NCE)) supplied biologic and self-report data using the Youth Risk Behavior Surveillance System (YRBSS) and Computer...

background: interactions of free radicals from ionizing radiation with dna can induce dna damage and lead to mutagenesis and carsinogenesis. with respect to radiation damage to human, it is important to protect humans from side effects induced by ionizing radiation. in the present study, the effects of arbutin were investigated by using the micronucleus test for anti-clastogenic activity, to ca...
