Background: A key innovation may allow one group of species to radiate and replace another, but the role of competition and background extinctions for the replacement process is vigorously debated and unclear. Questions: Is a minimum competitive advantage necessary to initiate replacement? Are background extinctions of the incumbent species necessary? What speciation and extinction dynamics charac
It has been suggested that oxidative stress plays an important role in mediating excitotoxic neuronal death. We have therefore investigated the protective effects of antioxidants against excitotoxic injury in the rat on striatal neurons both in vitro and in vivo. In the first part of the study, we determined whether two different types of antioxidants, the spin trapping agent, alpha-phenyl-tert-bu
Background Sarcopenia and poor physical function are common in patients with chronic kidney disease (CKD). Our aim was to investigate the relationships between muscle mass and measured glomerular filtration rate (GFR) and between muscle mass and strength and balance, respectively, in patients with CKD stages 3–5. Methods This is a baseline data analysis of a randomized controlled clinical trial.
Adult and embryonic rabbit retinal sheets were transplanted into the subretinal space of adult rabbits. The transplants were either full-thickness with intact layering, or gelatin embedded and vibratome sectioned with the inner retina removed. The full-thickness grafts were positioned subretinally by means of a glass capillary in which they were partially folded. The vibratome sectioned ones were
Cirka 1000 barn föds med hjärtfel i Sverige varje år och idag överlever de flesta och uppnår vuxen ålder. Det finns uppskattningsvis 2.3 miljoner vuxna med medfött hjärtfel i Europa idag, en siffra som förväntas öka. Samtidigt har prevalensen av patienter med komplexa medfödda hjärtfel också ökat de senaste 10 åren. Det finns således ett behov av att öka kunskapen om patofysiologin vid dessa sjukd
Aims/hypothesis: The aim of this study was to analyse patterns of continuous glucose monitoring (CGM) data for associations with large for gestational age (LGA) infants and an adverse neonatal composite outcome (NCO) in pregnancies in women with type 1 diabetes. Methods: This was an observational cohort study of 186 pregnant women with type 1 diabetes in Sweden. The interstitial glucose readings f
Context. Streaming instability is a key mechanism in planet formation, clustering pebbles into planetesimals with the help of self-gravity. It is triggered at a particular disk location where the local volume density of solids exceeds that of the gas. After their formation, planetesimals can grow into protoplanets by feeding from other planetesimals in the birth ring as well as by accreting inward
Grafts of five different types of central cholinergic neurons, from the septal-diagonal band region, the nucleus basalis magnocellularis region (NBM), the striatum, the pontomesencephalic tegmentum of the brainstem, and the spinal cord, were compared with respect to their ability to grow and to reinnervate the cholinergically denervated hippocampal formation of adult rats. The areas were dissected
BACKGROUND: Abiraterone acetate, a drug that blocks endogenous androgen synthesis, plus prednisone is indicated for metastatic castration-resistant prostate cancer. We evaluated the clinical benefit of abiraterone acetate plus prednisone with androgen-deprivation therapy in patients with newly diagnosed, metastatic, castration-sensitive prostate cancer.METHODS: In this double-blind, placebo-contro
During World War II, Nils Hylander worked on his monumental theses about the wood lawn neophytes [German: Grassameneinkömmlinge] of Swedish parks. Most probably, the original aim was to date and locate the sources of the imported seed that had obviously been widely used in the 1800’s for establishing lawns in parks of the English style, but due to restrictions to work and travel during the war, H
Background: An accurate medication list at hospital admission is essential for the evaluation and further treatment of patients. The objective of this study was to describe the frequency, type and predictors of errors in medication history, and to evaluate the extent to which standard care corrects these errors.Methods: A descriptive study was carried out in two medical wards in a Swedish hospital
Purpose: To quantify fixation stability in patients with neovascular age-related macular degeneration (nAMD) at baseline, 3 and 6 months after anti-vascular endothelial growth factor (anti-VEGF) treatment and furthermore asses the implications of an unsteady fixation for multifocal electroretinography (mfERG) measurements. Methods: Fifty eyes of 50 nAMD patients receiving intravitreal anti-VEGF tr
It is easy when studying the literature on the current development toward closer more integrated business to business relationships to get the impression that a close integrated relationship is desired for all circumstances. Instead, this thesis shows that the nature of business relationship is very strongly correlated to product supplied. The focus of this thesis has been a case study between a s
Popular Abstract in Swedish För drygt 30 år sedan samlades några uttråkade ungdomar i Hultsfred, Småland och bildade rockföreningen Rockparty. Föreningen byggde upp en omfattande konsertverksamhet och en stark musikscen på den lilla orten. 1986 startade Hultsfredsfestivalen, vilken utvecklades till ett av Sveriges starkaste varumärken. En festival som i decennier drog till sig inhemska och utländsBjälesjö, Jonas 2013.

Providing sufficient food for a growing global population is one of the fundamental global challenges today. Crop production needs not only to be increased, but also remain stable over the years, in order to limit the vulnerability of producers and consumers to inter-annual weather variability, especially in areas of the world where the food consumed is mainly produced locally (e.g. Sub Saharan Af
The changing forms of governance stemming from the rise of New Public Management (NPM) and New Public Governance (NPG) have brought about significant changes in the relationship between the public and private sectors (Christensen and Lægreid 2007; Torfing and Triantafillou 2013). Not only have we witnessed a gradual increase in the involvement of private actors in the provision of public services,
In the article, the Great Conflict of 1980 is compared with the general strike and great lockout of 1909 and the 1945 metalworkers’ strike. Depending on how they are measured, each of them could lay claim to be the largest labour conflict in Swedish history. While the strikes of 1909 and 1945 ended up in union defeats, the outcome of the 1980 conflict was a severe setback for SAF. The 1909 LO stri
Abstract Fatty acids mobilized from triacylglycerol stores are a major energy source in humans. Mobilization occurs through the consecutive action of three lipases: adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL) and monoglyceride lipase (MGL). Whereas ATGL and MGL only hydrolyse tri- and monoacylglycerols, respectively, HSL has a broad substrate range and hydrolyses cholesterol
The organisational network of global environmental governance (GEG) mirrors the complexity of the planet's manifold and overlapping ecosystems. Bursting onto the international stage in the 1970s, environmental issues began to be addressed by a series of new international organisations, most of them affiliated with the United Nations. Some of them, such as the United Nations Environment Programme (
