A giant exoplanet orbiting a very-low-mass star challenges planet formation models

Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion theory of planet formation. We report the discovery of a giant planet around the very-low-mass star GJ 3512, as determined by optical and near-infrared radial-velocity observations. The planet has a minimum mass of 0.46 Jupiter masses, very hig

Fat loss in continuous enteral feeding of the preterm infant : How much, what and when is it lost?

Human milk fat is a concentrated source of energy and provides essential and long chain polyunsaturated fatty acids. According to previous experiments, human milk fat is partially lost during continuous enteral nutrition. However, these experiments were done over relatively short infusion times, and a complete profile of the lost fatty acids was never measured. Whether this loss happens considerin

Stem Cells, Cell Therapies, and Bioengineering in Lung Biology and Diseases 2017 : An Official American Thoracic Society Workshop Report

The University of Vermont Larner College of Medicine, in collaboration with the National Heart, Lung, and Blood Institute (NHLBI), the Alpha-1 Foundation, the American Thoracic Society, the Cystic Fibrosis Foundation, the European Respiratory Society, the International Society for Cell & Gene Therapy, and the Pulmonary Fibrosis Foundation, convened a workshop titled "Stem Cells, Cell Therapies

Oxygen supply to immobilized cells : 2. Studies on a coimmobilized algae-bacteria preparation with in situ oxygen generation

A coimmobilized mixed culture of algae, Chlorella pyrenoidosa, and bacteria, Gluconobacter oxydans, has been studied. The conversion of glycerol to dihydroxyacetone(1,3-dihydroxy-2-propanone), catalysed by the bacteria, was used to indicate the oxygen supply in the immobilized preparation. The oxygen produced by the algae in the coimmobilized preparation was used by the bacteria more effectively t

För integrationens skull? : Frågan om rösträtt för invandrare utan svenskt medborgarskap under efterkrigstiden

In 1975, Sweden extended voting rights in local elections toimmigrants without Swedish citizenship (resident aliens). In thisarticle, I show that the arguments behind the reform were based on a wish to speed up the integration of immigrants ratherthan normative ideas about the nature of democracy. The reform was in fact seen as part of the emerging Swedishintegration policy. Almost a decade later,

Erenumab (AMG 334), a monoclonal antagonist antibody against the canonical CGRP receptor, does not impair vasodilatory or contractile responses to other vasoactive agents in human isolated cranial arteries

Background: Calcitonin gene-related peptide (CGRP) is a neuronal transmitter present in intracranial sensory nerves, where it is involved in migraine pathophysiology as well as other biological functions. Recently, the fully human monoclonal antibody erenumab (AMG 334), which targets the canonical calcitonin gene-related peptide receptor, showed significant prophylactic efficacy and favourable saf

Identification and characterization of novel small-molecule protease-activated receptor 2 agonists

We report the first small-molecule protease-activated receptor (PAR) 2 agonists, AC-55541 [N-[[1-(3-bromo-phenyl)-eth-(E)-ylidene-hydrazinocarbonyl]- (4-oxo-3,4-dihydro-phthalazin-1-yl)-methyl]-benzamide] and AC-264613 [2-oxo-4-phenylpyrrolidine-3-carboxylic acid [1-(3-bromo-phenyl)-(E/Z)- ethylidene]-hydrazide], each representing a distinct chemical series. AC-55541 and AC-264613 each activated P

Offshore outsourcing : An IT-manager perspective on cultural differences

— Cultural difference is a term often used when discussing problems in offshoring and offshore outsourcing, but only a few authors discuss solutions to bridge pointed out cultural gaps. In this paper earlier research is compared with an IT-manager perspective on experienced cultural differences. Cultural differences were found to include multiple dimensions: cultural distances, cognitive distances

The differences in the T2 relaxation rates of the protons in the partially-deuteriated and fully protonated sugar residues in a large oligo-DNA (‘NMR-window’) gives complementary structural information

Selective incorporation of the stereospeciflcally deuterlated sugar moieties (\lt;97 atom \% 2H enhancements at H2′, H2″, H3′ and H5′/5′ sites, ∑85 atom \% 2H enhancement at H4′ and ∑20 atom \% 2H enhancement at H1′) in DNA and RNA by the ‘NMR-window’ approach has been shown to solve the problem of the resonance overlap [refs. 1, 2 \amp; 3]. Such specific deuterium labelling gives much improved re

Localization and Regulation of Polymeric Ig Receptor in Healthy and Diseased Human Kidney

The polymeric Ig receptor (PIgR) constitutes an important part of the immune system by mediating transcytosis of dimeric IgA into mucosal fluids. Although well studied in organs such as the intestine, the regulation and localization of PIgR in human kidney are incompletely characterized. Herein, using immunohistochemistry, we show that in healthy human kidneys, PIgR is expressed by the progenitor-

The rate and perioperative mortality of caesarean section in Sierra Leone

Introduction Sierra Leone has the world's highest maternal mortality, partly due to low access to caesarean section. Limited data are available to guide improvement. In this study, we aimed to analyse the rate and mortality of caesarean sections in the country. Methods We conducted a retrospective study of all caesarean sections and all reported in-facility maternal deaths in Sierra Leone in 2016.

Clinical and angiographic outcomes of bioabsorbable vs. permanent polymer drug-eluting stents in Sweden : a report from the Swedish Coronary and Angioplasty Registry (SCAAR)

Aims: Randomized clinical trials have consistently demonstrated the non-inferiority of bioabsorbable polymer drug-eluting stents (BP-DES) with respect to DES having permanent polymers (PP-DES). To date, the comparative performance of BP- and PP-DES in the real world has not been extensively investigated. Methods and results: From October 2011 to June 2016, we analysed the outcomes associated with

Temporary in situ aluminum and zinc tethering in Diels-Alder reactions

(formula presented) Temporary tethering using aluminum or zinc in Diels-Alder reactions made possible the use of otherwise "noncompatible" combinations of dienes and dienophiles, resulting in the one-step formation of substituted cyclohexene 1,2-bis-methanols. Excellent regioselectivity and also significant stereoselectivity were obtained.

Factors to consider when implementing patient online access to their electronic health record.

Government and public agencies in Sweden have promoted the expansion of eHealth. The strategy behind this effort is to increase quality of care, efficiency, patient empowerment and patient safety, and one of the most important civic eHealth services is patient online access to electronic health records (EHR). By 2017, all of Sweden’s inhabitants will be able to access their EHR from somatic care t

Autoimmunogenetic Aspects of Vaccine-induced Narcolepsy. As part of the AMINA - Autoimmune Multiple Sclerosis and Narcolepsy Study.

Narcolepsy type 1 (NT1) is a neurological sleep disorder. The biological cause is the degeneration of hypocretin neurons located in the hypothalamus. It has been suggested that NT1 has an autoimmune pathogenesis, as in most patients, the Human Leukocyte Antigen (HLA)-DQB1*06:02:01 is present. An increased incidence of NT1 was observed in Sweden following the 2009 influenza Pandemrix®-vaccination.
