Role of proneurotensin as marker of paediatric coeliac disease
Neurotensin (NT) is a gut hormone functioning proinflammatory through nuclear factor kappa B (NF-κB) and interleukin (IL)−8 secretion or anti-inflammatory through epidermal growth factor receptors. NT mRNA is down-regulated in duodenal biopsies of children with untreated coeliac disease. The aim of this study was to investigate if plasma pro-NT levels correlated with the degree of intestinal mucos
Young, Small, and Imprintable : Assessing Progress and Exploring Future Directions in New Venture and Small Business Research
Liabilities of newness and smallness as well as other issues (e.g., “imprinting”) that affect nascent firms represent foundational entrepreneurship issues. The articles in this Special Issue examine if and how these critical issues have changed over time, especially given recent innovations (e.g., crowdfunding) and other trends in society. We believe that a special issue devoted to these topics is
Species and emm-type distribution of group C and G streptococci from different sites of isolation
beta-Haemolytic streptococci of groups C (GCS) and G (GGS) from human infections typically belong to Streptococcus dysgalactiae and are important human pathogens. Among GGS (183 isolates), several emm-types were identified without significant differences between different sites of isolation. For GCS (79 isolates), the type-distribution was markedly different and more restricted.
An age structured cell cycle model with crowding
We study a two compartment, nonlinear, age structured model for the cell cycle. The phases of the cell cycle G1, S, G2 and M are grouped into two phases, which we call Phase 1 and Phase 2, where Phase 1 consists of the phase G1 and Phase 2 consists of the phases S, G2 and M. It is assumed that Phase 1 has a variable duration while the duration of Phase 2 is fixed. The model consists of a system of
Interactive roles of the cerebellum and striatum in sub-second and supra-second timing : Support for an initiation, continuation, adjustment, and termination (ICAT) model of temporal processing
The contributions of cortico-cerebellar and cortico-striatal circuits to timing and time perception have often been a point of contention. In this review we propose that the cerebellum principally functions to reduce variability, through the detection of stimulus onsets and the sub-division of longer durations, thus contributing to both sub-second and supra-second timing. This sensitivity of the c
Climate regulation, energy provisioning and water purification : Quantifying ecosystem service delivery of bioenergy willow grown on riparian buffer zones using life cycle assessment
Whilst life cycle assessment (LCA) boundaries are expanded to account for negative indirect consequences of bioenergy such as indirect land use change (ILUC), ecosystem services such as water purification sometimes delivered by perennial bioenergy crops are typically neglected in LCA studies. Consequential LCA was applied to evaluate the significance of nutrient interception and retention on the e
A New Method for Endoscopic Sampling of Submucosal Tissue in the Gastrointestinal Tract : A Comparison of the Biopsy Forceps and a New Drill Instrument
Background. Sampling of submucosal lesions in the gastrointestinal tract through a flexible endoscope is a well-recognized clinical problem. One technique often used is endoscopic ultrasound-guided fine-needle aspiration, but it does not provide solid tissue biopsies with preserved architecture for histopathological evaluation. To obtain solid tissue biopsies from submucosal lesions, we have const
Impact of urban water supply on energy use in China : a provincial and national comparison
To reduce greenhouse gas (GHG) emissions and help mitigate climate change, urban water systems need to be adapted so that electrical energy use is minimised. In this study, energy data from 2011 was used to quantify energy use in China’s urban water supply sector. The objective was to calculate the energy co-benefits of urban water conservation policies and compare energy use between China and oth
Book reviews 2016
This section contains reviews of two Swedish books on international taxation. First, the book Skatteavtal och generalklausuler, Ett komparativt perspektiv (TaxAgreements and General Anti-Avoidance Regulations, A Comparative Perspective) is recommended for those who study and work with international tax law. The book analyses how tax treaties function to limit contracting states’taxing powers relat

Novel insights from coleopteran and pollen evidence into the Lateglacial/Holocene transition in Aubrac, French Massif Central
The aim of this study is to describe the environmental and climate changes that occurred in the mountains of Aubrac at the transition between the Lateglacial and the Holocene, from a comparative analysis of fossil Coleoptera and pollen, and a series of 23 14C dates. The changes affecting the ecological categories of Coleoptera lead to a division of the sequence into 5 beetle assemblage zones (BAZ)

Ictal EEG source imaging in presurgical evaluation : High agreement between analysis methods
Purpose To determine the agreement between five different methods of ictal EEG source imaging, and to assess their accuracy in presurgical evaluation of patients with focal epilepsy. It was hypothesized that high agreement between methods was associated with higher localization-accuracy. Methods EEGs were recorded with a 64-electrode array. Thirty-eight seizures from 22 patients were analyzed usin
The genetic diversity, phylogeography and morphology of Elphidiidae (Foraminifera) in the Northeast Atlantic
Genetic characterisation (SSU rRNA genotyping) and Scanning Electron Microscope (SEM) imaging of individual tests were used in tandem to determine the modern species richness of the foraminiferal family Elphidiidae (Elphidium, Haynesina and related genera) across the Northeast Atlantic shelf biomes. Specimens were collected at 25 locations from the High Arctic to Iberia, and a total of 1013 indivi
Changes in El Niño – Southern Oscillation (ENSO) conditions during the Greenland Stadial 1 (GS-1) chronozone revealed by New Zealand tree-rings
The warming trend at the end of the last glacial was disrupted by rapid cooling clearly identified in Greenland (Greenland Stadial 1 or GS-1) and Europe (Younger Dryas Stadial or YD). This reversal to glacial-like conditions is one of the best known examples of abrupt change but the exact timing and global spatial extent remain uncertain. Whilst the wider Atlantic region has a network of high-reso
Regulating planned obsolescence: a review of legal approaches to increase product durability and reparability in Europe
Improving product durability and reparability can save natural resources and money for consumers but may not always be in the best interest of all manufacturers. With the emergence of the circular economy as an important policy objective in the European Union (EU), there is renewed interest in policies to promote durability and address planned obsolescence. Different legislative approaches are cur
Cholelithiasis during the first year of life : Case reports and literature review
Five cases are reported of children with gallstones diagnosed by ultrasound during their first 7 months of life. Of the four with symptomatic gallstones, one subsequently developed vitamin K deficiency syndrome with profuse bleedings. The children, who belonged to a defined population, were all diagnosed within an 18-month span, suggesting the frequency of early gallstone formation to be higher th
