To determine possible effects of lifestyle, diet, housing and professional activities on differences in individual levels of decabromodiphenyl ether (BDE-209) in serum of women, 20 to 40years of age, in The Netherlands, the United Kingdom, Norway and Spain. BDE-209 was measured in serum of 145 female volunteers with no known occupational exposure from Norway, United Kingdom, The Netherlands and Spain. Blood levels of BDE-209 in a subgroup of 40 Dutch women were determined twice at a six months' interval. An extensive questionnaire was used to obtain detailed information about lifestyle factors that might contribute to BDE-209 exposure...

In this study, the organic components were identified that are mainly responsible for the formation of disinfection byproducts (DBPs) and for the biostability of urban surface water. The compositional distribution of dissolved organic matter (DOM) was strongly associated with the potential for both DBP formation and bacterial growth. Further evaluation was carried out (1) to compare the potential for DBP formation upon chlorination of treated water, (2) to determine the biostability that might result from minimizing assimilable organic carbon (AOC), and (3) to use laboratory-scale soil-column experiments to compare the effects of removal of trace organic chemicals (TOrCs) between managed aquifer recharge (MAR) hybrid systems (such as bank filtration followed by artificial recharge and recovery: ARR), and ozonation followed by ARR...

Neuroblastoma and other pediatric tumors show a paucity of gene mutations, which has sparked an interest in their epigenetic regulation. Several tumor types include phenotypically divergent cells, resembling cells from different lineage development stages. It has been proposed that super-enhancer-associated transcription factor (TF) networks underlie lineage identity, but the role of these enhancers in intratumoral heterogeneity is unknown. Here we show that most neuroblastomas include two types of tumor cells with divergent gene expression profiles...

This study describes the molecular characterization of an NDM-7 carbapenemase-producing Escherichia coli strain Ec188, recovered from a rectal swab of a male patient who had travelled to Pakistan before his hospitalization at the Hospital del Mar in Barcelona, Spain. The Ec188 isolate, assigned to a new multilocus sequence type ST679, was resistant to all beta-lactams, aminoglycosides (gentamicin, tobramycin, and with reduced susceptibility to amikacin), and ciprofloxacin. The blaNDM-7 gene was located on a 50 kb IncX4 plasmid (pEc188-NDM7), both in the original and transconjugant strains...

Mesenchymal stem cells (MSCs) not only can be differentiated into different cell types but also have tropism towards injured or inflamed tissues serving as repair cells. Here we have demonstrated that MSCs containing gold nanoparticles (GNPs) whose surface has been functionalized with PEG show accelerated cell migration, successful scaffold colonization and regeneration. We report the impact of GNPs on the migration (by the wound healing assay), and proliferation (by flow cytometry analysis and by the detection of metabolic mitochondrial activity) on the behaviour of different cell lines including MSCs, HeLa cells, and human dermal fibroblasts...

Space travel poses an enormous challenge on the human body; microgravity, ionizing radiation, absence of circadian rhythm, confinement and isolation are just some of the features associated with it. Obviously, all of the latter can have an impact on human physiology and even induce detrimental changes. Some organ systems have been studied thoroughly under space conditions, however, not much is known on the functional and morphological effects of spaceflight on the human central nervous system. Previous studies have already shown that central nervous system changes occur during and after spaceflight in the form of neurovestibular problems, alterations in cognitive function and sensory perception, cephalic fluid shifts and psychological disturbances...

BACKGROUND: Hypertriglyceridemia is common in HIV-infected patients. Polyunsaturated fatty acids reduce fasting serum triglyceride (TG) levels in HIV-infected patients. It is not known whether docosahexanoic acid (DHA) supplementation can reduce hypertriglyceridemia and modify fat distribution in HIV-infected patients. METHODS: We conducted a randomized, double-blind, placebo-controlled trial with 84 antiretroviral-treated patients who had fasting TG levels from 2...

Aspergillus flavus and Aspergillus parasiticus are mould species producers of aflatoxins (AFs) and may grow on dry-cured ham during the ripening process. In this study, the influence of different water activity (aw) and temperatures on the temporal relative expression of three genes involved in AFs biosynthesis and their relationship with AFs production on dry-cured ham-based medium were evaluated. In general, the regulatory aflR and aflS genes showed similar expression patterns, and the expression of the structural aflP gene was much higher than that obtained for aflR and aflS genes...

Neuroinflammation contributes significantly to the pathophysiology of stroke. Here we test the hypothesis that the type I interferon receptor (IFNAR1) plays a critical role in neural injury after stroke by regulating the resultant pro-inflammatory environment. Wild-type and IFNAR1(-/-) primary murine neurons and glia were exposed to oxygen glucose deprivation (OGD) and cell viability was assessed. Transient cerebral ischemia/reperfusion injury was induced by mid-cerebral artery occlusion (MCAO) in wild-type and IFNAR1(-/-) and IFNAR2(-/-) mice in vivo, and infarct size, and molecular parameters measured...

BACKGROUND: The number of commercial apps to improve health behaviours in children is growing rapidly. While this provides opportunities for promoting health, the content and quality of apps targeting children and adolescents is largely unexplored. This review systematically evaluated the content and quality of apps to improve diet, physical activity and sedentary behaviour in children and adolescents, and examined relationships of app quality ratings with number of app features and behaviour change techniques (BCTs) used...

INTRODUCTION: Borderline personality disorder (BPD) is a serious mental illness that centers on the inability to effectively regulate emotions. A large amount of BPD patients engage in non-suicidal self-injury (NSSI). Given the NSSI contributes to serious health risks, it is important to know why some BPD patients engage in NSSI and others do not. A possible associated factor of NSSI in BPD may be alexithymia, which reflects difficulties in identifying and communicating feelings. Therefore the aim of the present study was to investigate whether NSSI was associated with alexithymia and whether this association still stood when controlling for gender and depression...

Melatonin, an endogenously produced hormone, might potentially limit the ischemia reperfusion injury and improve the efficacy of mechanical reperfusion with primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI). This study was aimed to evaluate whether the treatment effect of melatonin therapy in patients with STEMI is influenced by the time to administration. We performed a post hoc analysis of the Melatonin Adjunct in the Acute Myocardial Infarction Treated With Angioplasty trial (NCT00640094), which randomized STEMI patients to melatonin (intravenous and intracoronary bolus) or placebo during pPCI...

The current outbreak of Zika virus has caused great social alarm, generated in part by the lack of information in the general population. In order to provide accurate and verified information, the Tropical and Travel Medicine Unit of Hospital Carlos III-La Paz (Madrid, Spain) established a hotline for Zika virus infection. We present the data concerning the first 6 months of operation of the telephone hotline. The predominant call profile consisted of women seeking information about the risk of acquiring the disease before travelling...

The Atacama Desert in Chile is the driest and oldest desert on Earth, also considered one of the best Mars analog models. Here, several heterotrophic microbial communities have been discovered in its driest regions, with the ones present in the soil subsurface being one of the most interesting due to its existence in a habitat with almost no water available and almost undetectable organic carbon sources. Our recent discovery of the driest site of the Atacama known to date (and the heterotrophic microbial species that are able to survive in this site) reaffirms the opportunity to better characterize the physiological and molecular mechanisms that these species use to detect, mobilize, incorporate and use carbon under these extremely harsh conditions...

In the presence of distraction, attentional filtering is a key predictor of efficient information storage in visual short-term memory (VSTM). Yet, the role of attention in distractor filtering, and the extent to which attentional filtering continues to protect information during post-perceptual stages of VSTM, remains largely unknown. In the current study, we investigated the role of spatial attention in distractor filtering during VSTM encoding and maintenance. Participants performed a change detection task with varying distractor load...
