Pyrethroids are insecticides frequently used in agriculture and in the home; exposure occurs through dietary and non-dietary pathways, including indoor and outdoor environmental contamination. Our objective was to study the potential determinants of pyrethroid metabolite concentrations measured in children's urine samples and in the dust of their homes. Specifically, we measured urinary metabolites from morning spot samples of 245 six-year-old children living in Brittany (France) in 2009-2012 and from dust vacuumed from the floor of their homes...

Histone H2B lysine 120 mono-ubiquitination (H2Bub1) catalyzed by Rnf20 has been implicated in normal differentiation of embryonic stem (ES) and adult stem cells. However, it remains unknown how Rnf20 is recruited to its specific target chromosomal loci for the establishment of H2Bub1. Here, we reveal that Fbxl19, a CxxC domain-containing protein, promotes H2Bub1 at the promoters of CpG island-containing genes by interacting with Rnf20. We show that up-regulation of Fbxl19 increases the level of global H2Bub1 in mouse ES cells, while down-regulation of Fbxl19 reduces the level of H2Bub1...

Rasch methods were used to evaluate and further develop the Daily Experiences of Pleasure, Productivity, and Restoration Profile (PPR Profile) into a health outcome measure of occupational experience. Analyses of 263 participant PPR Profiles focused on rating scale structure, dimensionality, and reliability. All rating scale categories increased with the intended meaning of the scales, but only 20 of the 21 category measures fit the Rasch rating scale model (RRSM). Several items also did not fit the RRSM and results of residual principal components analyses suggested possible second dimensions in each scale...

The interest in biomass fuel is continuing to expand globally and in the Northeastern US as wood pellets are becoming a primary source of fuel for residential and small commercial systems. Wood pellets for boilers are often stored in basement storage rooms or large bag type containers. Due to the enclosed nature of these storage areas, the atmosphere may exhibit increased levels of carbon monoxide. Serious accidents in Europe have been reported over the last decade in which high concentrations of carbon monoxide (CO) have been found in or near bulk pellet storage containers...

The T-cell factor/Lymphoid enhancer factor (TCF/LEF; hereafter TCF) family of transcription factors are critical regulators of colorectal cancer (CRC) cell growth. Of the four TCF family members, TCF7L1 functions predominantly as a repressor of gene expression. Few studies have addressed the role of TCF7L1 in CRC and only a handful of target genes regulated by this repressor are known. By silencing TCF7L1 expression in HCT116 cells, we show that it promotes cell proliferation and tumorigenesis in vivo by driving cell cycle progression...

The friction cost approach has been proposed as an alternative to the human capital approach in estimating productivity costs. However, it is difficult, in practice, to apply this approach due to limited availability of context-specific data. Using national and firm-level data on vacancy durations sourced from 4 organisations, we estimated vacancy durations, and consequently, length of friction period for the United Kingdom disaggregated by occupational classification. We found comparable estimates to previously reported friction periods elsewhere...

The aim of this study was to analyse the effect of age at onset on the long-term clinical, social and global outcomes of schizophrenia through a systematic review and a meta-analysis. Original studies were searched from Web of Science, PsycINFO, Pubmed and Scopus, as well as manually. Naturalistic studies with at least a 2-year follow-up were included. Of the 3509 search results, 81 articles fulfilled the inclusion criteria. The meta-analysis was performed in Stata as a random-effect analysis with correlation coefficients between age at onset and the outcomes (categorized into remission, relapse, hospitalization, positive symptoms, negative symptoms, total symptoms, general clinical outcome, employment, social/occupational functioning and global outcome)...

This study evaluates the environmental impacts of biorefinery products using consequential (CLCA) and attributional (ALCA) life cycle assessment (LCA) approaches. Within ALCA, economic allocation method was used to distribute impacts among the main products and the coproducts, whereas within the CLCA system expansion was adopted to avoid allocation. The study seeks to answer the questions (i) what is the environmental impacts of process integration?, and (ii) do CLCA and ALCA lead to different conclusions when applied to biorefinery?...

Indoor air pollution is an important environmental factor that contributes to the burden of various diseases. Long-term exposure to ambient air pollution is associated with telomere shortening. However, the association between chronic indoor air pollution from household fuel combustion and leukocyte telomere length has not been studied. In our study, 137 cancer-free non-smokers were recruited. Their exposure levels to indoor air pollution from 1985 to 2014 were assessed using a face-to-face interview questionnaire, and leukocyte telomere length (LTL) was measured using a monochrome multiplex quantitative PCR method...

BACKGROUND: Studies of workers exposed to benzene at average air concentrations below one part per million suggest that benzene, a known hematotoxin, causes hematopoietic damage even at low exposure levels. However, evidence of such effects outside of occupational settings and for other volatile organic compounds (VOCs) is limited. OBJECTIVE: To investigate associations between ambient exposures to five VOCs, including benzene, and hematologic parameters among adult residents of the U...

During 2003-2013, fatality rates for oil and gas extraction workers decreased for all causes of death except those associated with fall events, which increased 2% annually during 2003-2013 (1). To better understand risk factors for these events, CDC examined fatal fall events in the oil and gas extraction industry during 2005-2014 using data from case investigations conducted by the Occupational Safety and Health Administration (OSHA). Sixty-three fatal falls were identified, accounting for 15% of all fatal events...

BACKGROUND: Cardiovascular diseases are the main cause of death in most countries and the past two decades have shown a global increase. Hypertension (HTN) was found to be the leading risk factor in 2010 as qualified by Disability Adjusted Life Years. Epidemiological studies in this regard in Sri Lanka are scarce. Thus, describing epidemiological patterns of HTN in the Sri Lankan population will help policy makers in planning preventive healthcare programs and aid in preparing strategies to cope with the increasing demand for healthcare facilities...

BACKGROUND: Studies have consistently demonstrated the negative impact of childhood sexual abuse (CSA) on intimate relationships. The majority of studies have focused on revictimization in at-risk or clinical samples, with very few addressing the impact of CSA on otherwise well-functioning adults and even fewer investigating the psychological mechanisms involved. To fill this gap, this study focuses on the effect of CSA on "normative" (nonviolent) romantic relationships in otherwise well-functioning young women, and the mediating role of personality dimension self-criticism and attachment in this regard...

Many children fail to master fraction arithmetic even after years of instruction, a failure that hinders their learning of more advanced mathematics as well as their occupational success. To test hypotheses about why children have so many difficulties in this area, we created a computational model of fraction arithmetic learning and presented it with the problems from a widely used textbook series. The simulation generated many phenomena of children's fraction arithmetic performance through a small number of common learning mechanisms operating on a biased input set...

An increasing percentage of college students report being affected by ADHD behaviors, and this population is at increased risk of experiencing negative consequences associated with alcohol consumption. However, specific factors motivating alcohol consumption and contributing to negative outcomes among these individuals are not well understood. Recent work suggests alcohol expectancies may interact with ADHD behaviors to influence negative drinking-related outcomes among those with elevated inattention and/or hyperactivity-impulsivity...
