Abstract Objective. The postprandial acid pocket is suggested to be an important factor in the pathogenesis of gastroesophageal reflux disease (GERD) as it according to the theory extends into the distal esophagus. The aim of this study was to test the hypothesis that the acid pocket transverses the squamocolumnar junction (SCJ) and exposes the most distal esophagus to gastric acid for extended pe

A search is performed for top-quark pairs (t (t) over bar) produced together with a photon (gamma) with transverse energy greater than 20 GeV using a sample of t (t) over bar candidate events in final states with jets, missing transverse momentum, and one isolated electron or muon. The data set used corresponds to an integrated luminosity of 4.59 fb(-1) of proton-proton collisions at a center-of-m

Tomosynthesis (digital tomography) is a recently introduced low-dose alternative to CT in the evaluation of the lungs in patients with cystic fibrosis and pulmonary nodules. Previous studies have reported an adult effective dose of 0.12-0.13 mSv for chest tomosynthesis. The aim of this study was to determine the paediatric effective dose from the dose-area-product. During a 3-y period, 38 children

We have evaluated the efficiency of two popular end-point methods to calculate ligand-binding free energies, LIE (linear interaction energy) and MM/GBSA (molecular mechanics with generalized Born surface-area solvation), i.e. the computational effort needed to obtain estimates of a similar precision. As a test case, we use the binding of seven biotin analogues to avidin. The energy terms used by M

A search for Higgs boson production in association with a W or Z boson, in the H -> WW* decay channel, is performed with a data sample collected with the ATLAS detector at the LHC in proton-proton collisions at centre-of-mass energies root s = 7 TeV and 8TeV, corresponding to integrated luminosities of 4.5 fb(-1) and 20.3 fb(-1), respectively. The W H production mode is studied in two-lepton and t

Background Trauma and its complications contribute to morbidity and mortality in the general population. Trauma victims are susceptible to acute respiratory distress syndrome (ARDS) and sepsis. Polymorphonuclear leucocytes (PMNs) are activated after trauma and there is substantial evidence of their involvement in the development of ARDS. Activated PMNs release heparin-binding protein (HBP), a gran

The Swedish national register of severe alpha1-antitrypsin (AAT) deficiency was established in 1991. The main aims are to prospectively study the natural history of severe AAT deficiency, and to improve the knowledge of AAT deficiency. The inclusion criteria in the register are age ≥18 years, and the PiZ phenotype diagnosed by isoelectric focusing. The register is kept updated by means of repeated

Problematic internet use (PIU) has been linked to adverse outcomes in adolescence, but its association with child-to-parent violence (CPV) has rarely been examined. This study investigated whether problematic social media use and problematic gaming were associated with CPV in a school-based sample of Swedish adolescents and young adults. In bivariate analyses, both PIU domains showed dose-responseProblematic internet use (PIU) has been linked to adverse outcomes in adolescence, but its association with child-to-parent violence (CPV) has rarely been examined.

Smart grids are widely promoted as efficient, low-carbon solutions for energy transitions, yet their governance often treats digital infrastructure as immaterial and uniformly beneficial. This obscures the material, temporal, and justice dimensions that shape real-world outcomes. We introduce Circular Grid Governance (CGG), a framework that integrates circular-economy principles, lifecycle thinkin

The Amazon is rapidly approaching an ecological tipping point driven by deforestation, forest degradation and global climate change. These are visible issues that receive increasing political and public attention.However, the accelerating biocultural loss in the Amazon, including the extinction of Indigenous languages, the disruption of Indigenous and local knowledge systems, and the disintegratio

INTRODUCTION: Autoantibodies against insulin (IAA) are early appearing markers of autoimmunity against the pancreatic islet beta cells and predict progression to type 1 diabetes if additional islet autoantibodies also develop. It is still controversial if proinsulin rather than insulin is the primary autoantibody.METHODS: The aim of the present study was to compare the half-maximal concentration (

Sensory traits shape animal lifestyles due to the central role they play in retrieving and processing environmental information. However, being some of the most energetically expensive tissues to build and maintain, ecological demands often modulate investment in these organs. Evidence that ecology shapes the evolution of sensory traits is plenty, but is heavily biased towards vertebrates and has

Both high-mountain rivers and wet-based mountain glaciers are considered effective erosion agents. They acted alternatively or simultaneously during the late Quaternary in the Tatra Mountains (West Carpathians) thus producing a vast amount of clastic material that was subject to deposition, reworking and transportation downstream. A small fraction of that amount of the material is still preserved

Machado-Joseph disease (MJD/SCA3) is the most frequent dominant ataxia worldwide. It is caused by a (CAG)n expansion. MJD has two major ancestral backgrounds: the Machado lineage, found mainly in Portuguese families; and the Joseph lineage, present in all five continents, probably originating in Asia. MJD has been described in a few African and African-American families, but here we report the fir

Objective: The aim was to investigate associations between dental healthcare utilization and all-cause, cardiovascular (CVD), cancer, and other-cause mortality. Materials and methods: A postal public health survey was distributed in the autumn of 2008 to a strat-ified random sample of the population aged 18–80 in Scania, southern Sweden (response rate 54.1%). Baseline survey data were linked to mo

BACKGROUND: Tailored and culturally appropriate latent tuberculosis (TB) infection screening and treatment programs, including interventions against TB stigma, are needed to reduce TB incidence in low TB incidence countries. However, we lack insights in stigma related to latent TB infection (LTBI) among target groups, such as asylum seekers and refugees. We therefore studied knowledge, attitudes,

Background: Familial cancer can be defined through the occurrence of the same cancer in two or more family members. We describe a nationwide landscape of familial cancer, including its frequency and the risk that it conveys, by using the largest family database in the world with complete family structures and medically confirmed cancers. Patients/methods: We employed standardized incidence ratios

Background: Allergic contact dermatitis from glucose sensors may interfere with their ongoing application. Objective: To evaluate a series of Spanish patients with contact dermatitis to glucose sensors regarding former sources of contact allergens, patch test results, and outcomes from the ongoing use of the device. Methods: A series of patients with contact dermatitis from glucose sensors was inv
