Association between plasma leptin and blood pressure in two population-based samples of children and adolescents

Objectives In this study we examined the association between leptin and blood pressure in a population-based study of Danish and Norwegian children and adolescents. Because of the putative bidirectional relationship between leptin and adiposity we formally tested (i) the mediating effect of body mass index in the association between leptin and blood pressure, and (ii) the mediating effect of lepti

Search for strong gravity signatures in same-sign dimuon final states using the ATLAS detector at the LHC

A search for microscopic black holes has been performed in a same-sign dimuon final state using 1.3 fb(-1) of proton-proton collision data collected with the ATLAS detector at a centre of mass energy of 7 TeV at the CERN Large Hadron Collider. The data are found to be consistent with the expectation from the Standard Model and the results are used to derive exclusion contours in the context of a l

Pressurized hot water extraction of bioactives

The purpose of this review is to give the reader a thorough background to the fundamentals and applications of pressurized hot water extraction (PHWE) for the analysis of bioactive compounds. We summarize the field in the period 2009-14, and include fundamentals of water as a solvent: equipment; method optimization; applications; coupling; and, future prospects. We highlight that solvent propertie

Reflections on responsibility and justice Coaching human rights in South Africa

Purpose - The purpose of this article is to question whether business is ethical as long as it follows rules, and on this view, to reflect over the relation between responsibility and justice. Design/methodology/approach - To exemplify this relation, the paper is based on in-depth interviews with a human rights consultant. In this way, the paper presents a story from the field and thus follows a n

Snail herbivory decreases cyanobacterial abundance and lichen diversity along cracks of limestone pavements

Herbivores are known to decrease plant species diversity in ecosystems with low productivity. Limestone pavements are low-productive habitats harboring specialized communities of cyanobacteria, and endo- and epilithic lichens exposed to extreme temperature and humidity fluctuations. Pavements of the Great Alvar (O¨ land, Sweden) are covered by free-living cyanobacteria giving the rock surface a da

Climate-induced reaction norms for life-history traits in pythons

Climate change modelers predict increasingly frequent "extreme events," so it is critical to quantify whether organismal responses (such as reproductive output) measured over the range of usual climatic conditions can predict responses under more extreme conditions. In a 20-year field study on water pythons (Liasis fuscus), we quantified the effects of climatically driven annual variation in food

Outer Partial Actions and Partial Skew Group Rings

We extend the classical notion of an outer action alpha of a group G on a unital ring A to the case when alpha is a partial action on ideals, all of which have local units. We show that if alpha is an outer partial action of an abelian group G, then its associated partial skew group ring A(star alpha) G is simple if and only if A is G-simple. This result is applied to partial skew group rings asso

Bipolar Patients' Quality of Life in Mixed States: A Preliminary Qualitative Study

Background: Approximately 20% of patients with bipolar disorder experience mixed states. Mixed states are associated with more comorbidity, poorer treatment response and prognosis, increased relapse rate, and decreased functioning. This study aimed to produce in-depth knowledge about bipolar patients' quality of life (QoL) and functioning related to mixed states. Sampling and Methods: This study u

Growth of asteroids, planetary embryos, and Kuiper belt objects by chondrule accretion.

Chondrules are millimeter-sized spherules that dominate primitive meteorites (chondrites) originating from the asteroid belt. The incorporation of chondrules into asteroidal bodies must be an important step in planet formation, but the mechanism is not understood. We show that the main growth of asteroids can result from gas drag-assisted accretion of chondrules. The largest planetesimals of a pop

Clinical probability assessment and biochemical markers in the diagnosis of deep vein thrombosis

Popular Abstract in Swedish Övergripande syfte Syftet med avhandlingen var att utvärdera hur en förenklad metod för diagnostisering av blodproppar i benets djupa ådror (djup ventrombos (DVT)) fungerar i svensk rutinsjukvård. Den förenklade metoden innebär användning av en strukturerad klinisk sannolikhetsbedömning tillsammans med ett blodprov (D-dimer test). Vi jämförde också vår D-dimermetod med The combination of pre-test clinical probability assessment and D-dimer test is now widely applied in the diagnostic process of DVT. The general objective of the present investigation was to validate these results in a Swedish routine emergency setting were the prevalence of the disease is high and were the clinical probability assessment was handled by many junior physicians. Furthermore, our aim

Resonant inelastic X-ray scattering spectrometer with 25 meV resolution at the Cu K-edge

An unparalleled resolution is reported with an inelastic X-ray scattering instrument at the Cu K-edge. Based on a segmented concave analyzer, featuring single-crystal quartz (SiO2) pixels, the spectrometer delivers a resolution near 25 meV (FWHM) at 8981 eV. Besides the quartz analyzer, the performance of the spectrometer relies on a four-bounce Si(553) high-resolution monochromator and focusing K

Feedback control of cerebellar learning

The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. However, except in a metaphorical sense, the cerebellum, which consists of a set of interco

Producing Precise Outcomes in Randomized, Controlled Trials and Clinical Studies

Evidence-based medicine (EBM) uses the current best evidence to inform decisions about care of individual patients, healthcare procedures, and technologies. The "gold standard" for optimal evidence in the Cochrane system is Level I randomized, controlled trials (RCTs) and meta-analyses of several RCTs. In order to achieve this level of evidence, one of the most important measures is the use of out

MIPs as Tools in Environmental Biotechnology.

: Molecular imprints are potentially fantastic constructions. They are selective, robust, and nonbiodegradable if produced from stable polymers. A range of different applications has been presented, everything from separation of enantiomers, via adsorbents for sample preparation before analysis to applications in wastewater treatment. This chapter deals with molecularly imprinted polymers (MIPs) a

Surface behavior of amphiphiles in aqueous solution: a comparison between different pentanol isomers

Position isomerism is ubiquitous in atmospheric oxidation reactions. Therefore, we have compared surface-active oxygenated amphiphilic isomers (1- and 3-pentanol) at the aqueous surface with surface- and chemically sensitive X-ray photoelectron spectroscopy (XPS), which reveals information about the surface structure on a molecular level. The experimental data are complemented with molecular dynam
