Kolinfosfolipider, en nyttig kostkomponent vid alkoholfettlever, NAFLD och NASH?Åke Nilsson, Rui-Dong DuanBakgrundKolin (trimetyletanolamin) ingår i fosfatidylkolin (PC) och sfingomyelin (SM) som finns i alla cellmembraner och i plasmalipoproteiner, och i acetylkolin. Även om levern bildar en del kolin klassas kolin som ett essentiellt näringsämne. Kolinbrist ger bl a fettlever, muskelsymptom och
Background and purpose — Obesity has been associated with inferior outcomes after laminectomy due to central lumbar spinal stenosis (CLSS); we evaluated whether this occurs in surgery on national bases. Patients and methods — We retrieved pre-and 1-year postoperative data from the National Swedish Quality Registry for Spine Surgery regarding patients aged ≥ 50 with laminectomy due to CLSS in 2005–
A search for the standard model Higgs boson produced in association with a top-quark pair, ttH, is presented. The analysis uses 36.1 fb-1 of pp collision data at s=13 TeV collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search targets the H→bb decay mode. The selected events contain either one or two electrons or muons from the top-quark decays, and are then cat
BACKGROUND AND OBJECTIVES: Degarelix is a gonadotropin-releasing hormone antagonist registered for the treatment of advanced hormone-dependent prostate cancer. Treatment causing androgen deprivation is associated with QT prolongation and this study investigated whether degarelix at supratherapeutic concentrations has an intrinsic effect per se on cardiac repolarisation and the QT interval.METHODS:
Background: Traumatic brain injuries continue to be a significant cause of mortality and morbidity worldwide. Most traumatic brain injuries are classified as mild, with a low but not negligible risk of intracranial hemorrhage. To help physicians decide which patients might benefit from a computerized tomography (CT) of the head to rule out intracranial hemorrhage, several clinical decision rules h
The need for modelling of materials behaviour under various mechanical conditions is driven by the evolution of computer capacity and the ability of scientists to address complex mechanical problems. Reliable models for materials behaviour, including accurate numerical values of parameters, are necessary for a continued beneficial development of the computational side of solid mechanics. High rate
This paper presents a dedicated search for exotic decays of the Higgs boson to a pair of new spin-zero particles, H→ aa, where the particle a decays to b-quarks and has a mass in the range of 20–60 GeV. The search is performed in events where the Higgs boson is produced in association with a W boson, giving rise to a signature of a lepton (electron or muon), missing transverse momentum, and multip
A search for the standard model Higgs boson produced in association with a vector boson with the decay H→ττ is presented. The data correspond to 20.3 fb-1 of integrated luminosity from proton-proton collisions at s=8 TeV recorded by the ATLAS experiment at the LHC during 2012. The data agree with the background expectation, and 95% confidence-level upper limits are placed on the cross section of t
Most models to predict biochemical recurrence (BCR) of prostate cancer use pretreatment serum prostate-specific antigen (PSA), clinical stage and prostate biopsy Gleason grade. We investigated whether human glandular kallikrein 2 (hK2) and free prostate-specific antigen (fPSA) measured in pretreatment serum enhance prediction. We retrospectively measured total PSA (tPSA), fPSA and hK2 in preoperat
PURPOSE: The partial volume effect (PVE) is an important source of bias in brain perfusion measurements. The impact of tissue PVEs in perfusion measurements with dynamic susceptibility contrast MRI (DSC-MRI) has not yet been well established. The purpose of this study was to suggest a partial volume correction (PVC) approach for DSC-MRI and to study how PVC affects DSC-MRI perfusion results.METHOD
In England saltmarshes account for less than 0.5% of the land area, however they have a very high biodiversity value and provide significant economic and social worth. Climate change, continuous coastal urbanisation, and port development are a serious concern for coastal protection planners, city councils and the government. It is a challenge for these decision makers to balance the social, econom
IVF och världsbanken är två grundpelare i det ekonomiska systemet. Ända sedan deras födelse vid Bretton Woods konferensen 1944 har de varit nyckelaktörer i uppbyggnaden av ekonomier. På senare år har organisationerna varit verksamma i att övervaka det monetära systemet och i kriget mot fattigdom världen runt. Men vad är det egentligen som skiljer de två organisationerna åt och vilka konsekvenser f
Att härleda ett internationellt illegalt handlande till en viss stat och hålla denna ansvarig är ett komplext problem i folkrätten. Det oklara rättsläget kompliceras ytterligare när aspekter av cyberoperationer introduceras med den snabba globala teknologiska utvecklingen. Rättsläget som det ser ut just nu är baserat på doktrin och sekundärrätt, där vikt läggs vid den tekniska bevisningen för att Attributing internationally wrongful acts to a particular State and liability is a complex problem in international law. The already unclear legal situation is further complicated when aspects of cyber operations are introduced with the rapid global technological development. To hold a State liable for the actions of non-State actors in cyberspace, we can only use secondary law and doctrine. The l
Background : Currently, antiretroviral therapy (ART) is recommended for all HIV-positive patients with tuberculosis (TB). The timing of ART during the course of anti-TB treatment is based on CD4 cell counts. Access to CD4 cell testing is not universally available; this constitutes an obstacle for the provision of ART in low-income countries. Objective : To determine clinical variables associated w
Ända sedan Klein populariserade termen Anti-branding har dess tekniker använts för att vända organisationers egna varumärken mot dem, och på så sätt sprida kritiska budskap. Med utvecklingen av sociala media utmanas många av förutsättningarna för att driva varumärkeskommunikation. Hur organisationer kommunikativt kan hantera att bli utsatta för Anti-branding och mer specifikt hur introduktionen avEver since Klein popularised the term Anti-branding, organisations has been using it’s techniques to turn companies’ own brands against them and to communicate messages of critique. With the development of social media, many old trueisms regarding brand communication has had to been reevaluated. How organizations communicatively can handle being exposed to Anti-branding and more specifically how t
China is a mega-diversity country with abundant natural resources, and the richness of these resources is demonstrated to be relevant with the local people’s historical interactions between biophysical and sociocultural systems. If we are to maintain biodiversity and strike a balance between human well-being and ecosystem service, it is important to incorporate the local people and their tradition
Purpose: The Extremely Preterm Infants in Sweden Study (EXPRESS) followed a national cohort of extremely preterm born (EPT, i.e. <27 weeks) children until 12 years of age. This study aimed to investigate the longitudinal development of visual acuity (VA) in children born EPT, explore the predictive value of early visual assessments, and evaluate risk factors for visual impairment at the age of 12
An estimated 6% of human greenhouse gas emissions are the result of enteric methane production by cows. Asparagopsis taxiformis, a semi-tropical alga, is one solution. Supplementation of this alga to cows at a small percentage of their daily intake has reduced methane emissions by over 98% in trials. This success has led to multiple commercialization attempts globally, although no Asparagopsis tax
Background: This study explored peer-led sex education for individuals with intellectual disabilities and/or autism (ID/ASD) from the perspective of project leaders within Swedish non-governmental organizations (NGOs). The purpose of this Grounded Theory study was to develop a conceptual model that characterizes the ways in which peer-led sex education is implemented by Swedish NGOs. This was done
