A new design of equilibrium hollow fibre liquid phase microextraction (HF-LPME) was developed for the determination of three freely dissolved organophosphorus pesticides (OPPs), i.e. diazinon (O,O-diethyl-O-2-isopropyl-4-methyl-6-pyrimidyl thiophosphate), chlorpyrifos (O,O-diethyl-O-[3,5,6-trichloro-2-pyridyl] phosphorothioate), and fenthion (O,O-dimethyl-O-4-methylthio-m-tolyl phosphorothioate) a
Summary-The role of stress in the development of disease has been the subject of considerable research in the last few years. Stressful life events have been related to many physical and psychological disorders. The DSM-IV devoted Axis IV to these kinds of events. There is, however, scant information on the possible mediating role of sex on perception of stressful life events, or on the validation
Background Psychological stress is an independent risk factor for cardiovascular disease (CVD), but the mechanism by which stress is associated with CVD is not entirely understood. Although genetic factors are implied in both stress responsivity and cardiovascular reactivity, no studies to date have investigated their interactions with stress for cardiovascular end points. The objective was to elu
Two mathematical models of human thermal regulation include the rational Predicted Heat Strain (PHS) and the thermophysiological model by Fiala. The approaches of the models are different, however, they both aim at providing predictions of the thermophysiological responses to thermal environments of an average person. The aim of this study was to compare and analyze predictions of the two models a
Elephant Moraine (EET) 96029 is a CM carbonaceous chondrite regolith breccia with evidence for unusually mild aqueous alteration, a later phase of heating and terrestrial weathering. The presence of phyllosilicates and carbonates within chondrules and the fine-grained matrix indicates that this meteorite was aqueously altered in its parent body. Features showing that water-mediated processing was
Introduction Proximity and access to water have long been central to human culture and accordingly deliver countless societal benefits. Over 200 million people live on Europe's coastline, and aquatic environments are the top recreational destination in the region. In terms of public health, interactions with 'blue space' (eg, coasts, rivers, lakes) are often considered solely in terms of risk (eg,
Monitoring of forest carbon fluxes for the purpose of national greenhouse-gas inventorying and reporting are commonly based on repeated large-scale field measurements. Alternate approaches based on modelling of forest growth offers potential benefits such as cost savings and detailed assessments of involved carbon fluxes. We calculated the net primary productivity (NPP) of Swedish forests using tw
I present an alternative to a widely used item-bias analysis procedure known as the ANOVA method. The new method is based on the Johnson-Neyman procedure, which is a multiple regression-based technique with properties that can overcome the major weaknesses of the ANOVA method. I introduce the proposed procedure in a non-technical manner, provide an illustrative example, and suggest guidelines for
AIM: It is of interest to predict possible lifetime risk of type 1 diabetes (T1D) in young children for recruiting high-risk subjects into longitudinal studies of effective prevention strategies.METHODS: Utilizing a case-control study in Sweden, we applied a recently developed next generation targeted sequencing technology to genotype class II genes and applied an object-oriented regression to bui
A new method for rapid determination of ethanol was developed, using alcohol dehydrogenase as recognition element for the SIRE (R) (sensors based on injection of the recognition element) Biosensor, which is an amperometric biosensor. The method was simple, fast, accurate, specific and cost-effective. The recognition element solution used was stable at least for 24h in room temperature, and at leas
A 5-year follow-up study of 476 type I adult diabetic patients previously studied cross sectionally revealed that, during the observation period, 19 patients died and 30 developed cardiovascular or renal disease, such as myocardial infarction (n = 8), cerebrovascular disease (n = 3), amputation (n = 6), and renal insufficiency (n = 13). The patients were registered by one and the most-severe event
The disposition of Na2B12H11SH (BSH) in patients with malignant glioma has been investigated, in preparation for a Phase I clinical trial of boron neutron capture therapy. BSH was found to possess a linear disposition over the dosage interval investigated (up to 75 mg/kg). A bi-phasic blood pharmacokinetics was observed. Tumour-to-blood ratios showed variations between patients between 0.08 and 5.
Lead is one of the poisonous elements for de-NOx catalysts especially in the case of municipal waste incineration plants. Samples of a commercial selective catalytic reduction catalyst were impregnated with different amounts of Pb(NO3)(2), and their catalytic activities were studied. The XPS and SEM analysis showed higher lead concentration on the outer surface of the monolith than on the inside o
High-resolution palynofloral signatures through the Cretaceous-Palaeogene boundary succession show several features in common with the Permian-Triassic transition but there are also important differences. Southern Hemisphere Cretaceous-Palaeogene successions, to date studied at high resolution only in New Zealand, reveal a diverse palynoflora abruptly replaced by fungi-dominated assemblages that a
BACKGROUND:: In soft tissue sarcoma, better distinction of high-risk and low-risk patients is needed to individualize treatment and improve survival. Prognostic systems used in clinical practice identify high-risk patients based on various factors, including age, tumor size and depth, histological type, necrosis, and grade. METHODS:: Whole-tumor sections from 239 soft tissue sarcomas of the extrem
The article reflects on the mechanisms aimed to control the fulfillment of the EU sustainability criteria for biofuels, as they were promoted in Directive 2009/28/EC. The article contains the final results of the research initiated in the work Pavlovskaia, E. (2013) “Controlling the Fulfillment of the EU Sustainability Criteria for Transport Biofuels”, which was published in RELP 4/2013. The artic
Purpose: To assess performance of a biomarker-based score that predicts the five-year risk of diabetes (Diabetes Risk Score, DRS) in an independent cohort that included 15-year follow-up. Method: DRS was developed on the Inter99 cohort, and validated on the Botnia cohort. Performance was benchmarked against other risk-assessment tools comparing calibration, time to event analysis, and net reclassi
This study evaluated automated techniques including personalized normative feedback and protective behavioral strategies, for brief interventions intended to reduce peak alcohol concentrations in university students. After completing baseline assessment, a total of 1,678 hazardous-drinking consumers were randomized to a single or a repeated Internet (WEB) or Interactive Voice Response (IVR) interv
Family caregivers play a critical role in caring for children living with HIV, however, there is little knowledge about their experiences. The aim of this study was to illuminate the family caregivers' lived experiences of caring for a child when he or she has been diagnosed with HIV and enrolled to antiretroviral treatment. Qualitative interviews with 21 family caregivers of 21 children diagnosed
