Novel CO2 capture systems, consisting of 2-amino-2-methyl-1-propanol (AMP), a sterically hindered amine, in the organic solvents N-methyl-2-pyrrolidone (NMP) or triethylene glycol dimethyl ether (TEGDME) have been under investigation as an economical solution to the post combustion carbon capture problem. The carbamate formed during reaction with CO2 may precipitate during absorption and be regene
Background: Contact allergy to aluminium has been reported more frequently in recent years. It has been pointed out that positive patch test reactions to aluminium may not be reproducible on retesting. Objectives: To investigate possible variations in patch test reactivity to aluminium over time. Methods: Twenty-one adults, who had previously reacted positively to aluminium, were patch tested with
Background: Although oxygen (O2) is routinely used in patients with acute myocardial infarction (AMI), it may have negative effects. In this substudy of the SOCCER trial, we aimed to evaluate the effects of O2-treatment on myocardial function in patients with ST elevation myocardial infarction (STEMI). Methods: Normoxic (≥94%) STEMI patients were randomized in the ambulance to either supplemental
Background: There are currently no methods in clinical use that can detect early systemic dissemination of urothelial tumor cells. Objective: To evaluate measurement of circulating tumor cells (CTCs) as a biomarker for disseminated disease in patients with advanced bladder cancer. Design, setting, and participants: Between March 2013 and October 2015, 88 patients were prospectively included in the
Ytan av alla celler är dekorerad med kolhydrater som står för mycket av den information en cell överför till omgivande celler. Många av kolhydraterna tillhör en föreningsklass som kallas proteoglykaner som består av ett protein sammanbundet med en eller flera långa kolhydratkedjor. Dessa kolhydratkedjor kallas glykosaminoglykaner och är bundna till proteinet via kolhydraten xylos. Än så länge har β-1,4-Galactosyltransferase 7 (β4GalT7) is a key enzyme in the biosynthesis of proteoglycans (PGs) and glycosaminoglycan (GAG) chains, which are important macromolecules involved in many biological processes such as cell growth and cell signaling as well as in cancer pathobiology and viral and bacterial infections. Despite its pivotal role, much is still unknown regarding the specific structure of
This article discusses employment of crowds to make the change in Yemen.
This thesis is based on nine papers, all concerned with parameter estimation. The thesis aims at solving problems related to real-world applications such as spectroscopy, DNA sequencing, and audio processing, using sparse modeling heuristics. For the problems considered in this thesis, one is not only concerned with finding the parameters in the signal model, but also to determine the number of siThis thesis is based on nine papers, all concerned with parameter estimation.

Purpose: The purpose of this paper is to explore how organizational design could support teamwork and to identify organizational design principles that promote successful teamwork. Design/methodology/approach: Since traditional team training sessions take resources away from production, the alternative approach pursued here explores the promotion of teamwork by means of organizational design. A wi
Resistance to systemic therapy is a major problem in metastatic breast cancer (MBC) that can be explained by initial tumor heterogeneity as well as by evolutionary changes during therapy and tumor progression. Circulating tumor cells (CTCs) detected in a liquid biopsy can be sampled and characterized repeatedly during therapy in order to monitor treatment response and disease progression. Our aim
A glomus tumor of uncertain malignant potential is defined as a glomus tumor with some, but not all, criteria for malignancy and without a known metastasis. Here, we present a rare example presenting in the median nerve in a 40-year-old woman with a long history of severely impaired left median nerve function. A large panel of immunohistochemical stains excluded other diagnoses, and the designatio
Aim: Asphyxiated neonates should be resuscitated with air, but it remains unclear if oxygen supplementation is needed in ineffectively ventilated newborn infants. We studied the return of spontaneous circulation (ROSC) with oxygen or air in an experimental model of inadequate ventilation. Methods: Asphyxia was induced in 16 newborn piglets until their heart rate was <60 bpm or mean arterial pressu
MicroRNAs (miRNAs) are short non-coding RNAs that modulate gene expression post-transcriptionally. Current evidence suggests that miR-21 plays a significant role in the progression of fibrosis in muscle diseases. Laminin-deficient congenital muscular dystrophy (LAMA2-CMD) is a severe form of congenital muscular dystrophy caused by mutations in the gene encoding laminin α2 chain. Mouse models dy3K/
Objective: Metabolic complications are frequent in childhood leukaemia (ALL) survivors treated with cranial radiotherapy (CRT). These complications are potentially mediated by damage to the hypothalamus (HT), as childhood onset (CO) craniopharyngioma (CP) survivors without HT involvement are spared overt obesity. Diffusion tensor imaging (DTI) shows brain tissue microstructure alterations, by frac
Background/Aim: To compare human papillomavirus (HPV) DNA detection in self-collected vaginal and urine samples with clinician-taken cervical samples in relation to histology. Materials and Methods: Self-collected vaginal, urine and clinician-taken cervical samples were analyzed from 218 women with the Cobas 4800 HPV test (Roche Molecular Diagnostics). Results: The sensitivity for detection of HPV
Predicting the sign of press perturbation responses in ecological networks is challenging, due to the poor knowledge of the strength of the direct interactions among the species, and to the entangled coexistence of direct and indirect effects. We show in this paper that, for a class of networks that includes mutualistic and monotone networks, the sign of press perturbation responses can be qualita
Objectives To study the association between lifestyle risk factors and chronic hypertension by history of hypertensive disorders of pregnancy (HDP: gestational hypertension and pre-eclampsia) and investigate the extent to which these risk factors modify the association between HDP and chronic hypertension. Design Prospective cohort study. Setting Nurses' Health Study II (1991-2013). Participants 5
