Structural basis for the unique ganglioside and cell membrane recognition mechanism of botulinum neurotoxin DC

Botulinum neurotoxins (BoNTs), the most potent toxins known, are potential bioterrorism agents. It is well established that all seven serotypes of BoNTs (BoNT/A-G) require complex gangliosides as co-receptors. Here, we report that BoNT/DC, a presumed mosaic toxin between BoNT/D and BoNT/C1, binds and enters efficiently into neurons lacking complex gangliosides and shows no reduction in toxicity in

A comprehensive structural, biochemical and biological profiling of the human NUDIX hydrolase family

The NUDIX enzymes are involved in cellular metabolism and homeostasis, as well as mRNA processing. Although highly conserved throughout all organisms, their biological roles and biochemical redundancies remain largely unclear. To address this, we globally resolve their individual properties and inter-relationships. We purify 18 of the human NUDIX proteins and screen 52 substrates, providing a subs

Properties of g→b¯b at small opening angles in pp collisions with the ATLAS detector at √s=13 TeV

The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to b-quark pairs is a unique probe into the properties of gluon fragmentation because identified b-tagged jets provide a proxy for the quark daughters of the initial gluon. In this study, key differential distributions related to the g→bb process are measured using 33 f

The fourteenth data release of the sloan digital sky survey : First spectroscopic data from the extended baryon oscillation spectroscopic survey and from the second phase of the apache point observatory galactic evolution experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative,

Search for four-top-quark production in the single-lepton and opposite-sign dilepton final states in pp collisions at s =13 TeV with the ATLAS detector

A search for four-top-quark production, tttt, is presented. It is based on proton-proton collision data with a center-of-mass energy s=13 TeV collected by the ATLAS detector at the Large Hadron Collider during the years 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb-1. Data are analyzed in both the single-lepton and opposite-sign dilepton channels, characterized by the presenc

A Varied Density-based Clustering Approach for Event Detection from Heterogeneous Twitter Data

Extracting the latent knowledge from Twitter by applying spatial clustering on geotagged tweets provides the ability to discover events and their locations. DBSCAN (density-based spatial clustering of applications with noise), which has been widely used to retrieve events from geotagged tweets, cannot efficiently detect clusters when there is significant spatial heterogeneity in the dataset, as it

Towards a political economy of degrowth

Since the 1970s, the degrowth idea has been proposed by scholars, public intellectuals and activists as a powerful call to reject the obsession of neoliberal capitalism with economic growth, an obsession which continues apace despite the global ecological crisis and rising inequalities. In the past decade, degrowth has gained momentum and become an umbrella term for various social movements which

Product architecture, global operations networks, and operational performance : an exploratory study

This paper investigates the relationships between product architectures and global operations networks and their impact on operational performance, based on survey data from 82 Swedish manufacturers. We find that modular and integral product architectures are associated with different characteristics of the global operations network, and that global operations network designs are characterised by

A taxonomy of international manufacturing networks

Manufacturing firms with multiple product groups do not need to involve all factories in the production of all product groups. Some factories may specialize on a small set of products, while others participate in the manufacturing of a broader set of products. However, current theories on international manufacturing networks do not explain in detail how organizations design international manufactu

Phenotypic Refinement of Heart Failure in a National Biobank Facilitates Genetic Discovery

Heart failure (HF) is a morbid and heritable disorder for which the biological mechanisms are incompletely understood. We therefore examined genetic associations with HF in a large national biobank, and assessed whether refined phenotypic classification would facilitate genetic discovery. Methods: We defined all-cause HF among 488 010 participants from the UK Biobank and performed a genome-wide a

Postoperativa sårinfektioner inom hudkirurgi - En evidensöversikt : Orsakar onödigt lidande och ökade vårdkostnader, bästa förebyggande åtgärd ännu inte klarlagd

Surgical site infections (SSIs) in dermatologic surgery are rare, but when they do occur they can cause unnecessary suffering in patients, delayed healing, and result in poor scar cosmesis. The etiology and pathogenesis of SSIs in dermatologic surgery are not completely understood and most current preventative measures lack strong scientific evidence. Focusing on dermatologic surgery, this article

EU Competences and the Damages Directive: The Continuum Between Minimum and Full Harmonisation

This chapter examines the Damages Directive and the issue of competence allocation between the Union and the Member States, by analysing the degree of comprehensiveness and detail of the Directive as well as future perspectives of full harmonisation on EU level. It is argued that the distinction between minimumand full harmonisation is not particularly helpful. Instead, we suggest an alternative u

Är det detta som kallas postmodernism? : En studie i Katarina Frostensons och Stig Larssons diktning

During the 1980s the word ’postmodernism’ was inserted into the dicourse of Swedish literature in a curious way. Even though both writers and critics found the word bewildering – or deemed it a buzzword devoid of meaning – it sparked fierce debates. Despite this, and despite the fact that few wanted to be associated with the word, it has become common to describe the 1980s as the era of Swedish li

Parental and health care professional views on psychosocial and educational outcomes in patients with cleft lip and/or cleft palate

Background: Earlier research has investigated psychosocial and educational issues in populations of patients with cleft identifying several areas of concern. The objective of this study was to investigate current beliefs and knowledge about psychosocial and educational issues in parents and health care professionals (HCP) of children with cleft lip and/or palate (CL/P). Method: Parents were interv

Sperm chromatin structure assay high DNA stainability sperm as a marker of early miscarriage after intracytoplasmic sperm injection

Objective: To determine whether high DNA stainability (HDS), as assessed by the sperm chromatin structure assay (SCSA), predicts the risk of early miscarriage after in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI). Design: Retrospective cohort study of consecutive pregnancies after IVF and ICSI treatment. Setting: Reproductive medicine center. Patient(s): A total of 1,602 pr

Olika tillstånd av pulmonell hypertension ska inte förväxlas : PAH-läkemedel bör inte användas vid pulmonell hypertension på basen av vänstersidig hjärtsjukdom

Pulmonary hypertension is a common consequence of left heart disease, associated with poor prognosis. The pulmonary hypertension in left heart disease is initially caused by a passive congestion of the pulmonary circuit but may, if longstanding, result in endothelial dysfunction and excessive vasoconstriction. In some cases pulmonary vascular remodeling occur, further complicating the condition an
