This study assessed toxic potency of PFECHS in vivo during both acute (96-hour postfertilization) and chronic (21-day posthatch) exposures and tested concentrations of PFECHS from 500 ng/L to 2 mg/L. PFECHS was less likely to cause mortalities than PFOS for both the acute and chronic experiments based on previously published values for PFOS exposure, but exposure resulted in a similar incidence of deformities. (acs.org)
Exposure to PFECHS also resulted in significantly increased abundance of transcripts of peroxisome proliferator activated receptor alpha (pparα), cytochrome p450 1a1 (cyp1a1), and apolipoprotein IV (apoaIV) at concentrations nearing those of environmental relevance. (acs.org)

To examine the association between previous concussions and heading exposure with performance on computer based neuropsychological tests among professional Norwegian football players. (bmj.com)
Players in the Norwegian professional football league (Tippeligaen) performed two consecutive baseline neuropsychological tests (Cogsport) before the 2004 season (90.3% participation, n = 271) and completed a questionnaire assessing previous concussions, match heading exposure (self-reported number of heading actions per match), player career, etc. (bmj.com)
Neither match nor lifetime heading exposure was associated with neuropsychological test performance. (bmj.com)
Computerised neuropsychological testing revealed no evidence of neuropsychological impairment due to heading exposure or previous concussions in a cohort of Norwegian professional football players. (bmj.com)

The exposure might be through inhalation, ingestion, or dermal absorption. (ohsonline.com)
At 12 h after exposure, methacholine inhalation challenge tests and sputum induction were performed. (portlandpress.com)

Indoor exposure will be assessed by questionnaires and validated by measurements. (lu.se)

However, before discussing possible effects of radiofrequency-electromagnetic field (RF-EMF) on the human body, several factors must be investigated about the influence of EMFs at the level of research using in vitro or animal models. (nih.gov)
Conventional fixed-site pollution monitoring methods lack the spatial resolution needed to characterize these heterogeneous human exposures and localized pollution hotspots. (healtheffects.org)
