Semiconductor nanowires are key building blocks for the next generation of light-emitting diodes, solar cells and batteries. To fabricate functional nanowire-based devices on an industrial scale requires an efficient methodology that enables the mass production of nanowires with perfect crystallinity, reproducible and controlled dimensions and material composition, and low cost. So far there have
Aims/hypothesis Minimal model analysis for insulin sensitivity has been validated against the glucose clamp and is an accepted method for estimating insulin sensitivity from IVGTT. However minimal model analysis requires a 3 h test and relevant expertise to run the mathematical model. The aim of this study was to suggest a simple predictor of minimal model analysis index using only 1 h IVGTT. Meth
Background: Psychotic illness can have a substantial economic burden not only on the patient and society in general, but also on family members providing informal care (i.e. those not subject to a market wage). While informal caregiving confers benefits for the patient and society, time spent providing informal care is diverted from other activities such as work or leisure. Relatives and caregiver
Neo-sex chromosomes often originate from sex chromosome-autosome fusions and constitute an important basis for the study of gene degeneration and expression in a sex chromosomal context. Neo-sex chromosomes are known from many animal and plant lineages, but have not been reported in birds, a group in which genome organization seems particularly stable. Following indications of sex linkage and unex
Miniaturization of analytical separation methods offers several advantages, including short run times, high resolution, and high recovery of the sample constituents. To optimize these parameters, the reversible adsorption (to minimize loss in resolution), as well as the irreversible adsorption (to minimize loss of analytes) must be quantified. However, no useful equation is available for the calcu
Flow cytometry, morphometry and molecular markers [plastid DNA and internal transcribed spacers(ITS) of nuclear ribosomal DNA] were used to determine taxonomic and phylogeographic patterns in Dactylorhiza maculata s.l. from Scandinavia. A total of 238 individuals from 27 populations from throughout all of Scandinavia, including the adjacent Kola Peninsula of Russia, were analyzed. Diploid D. macul
The endogenous C18 N-acylethanolamines (NAEs) N-linolenoylethanolamine (18:3 NAE), N-linoleoylethanolamine (18:2 NAE), N-oleoylethanolamine (18:1 NAE), and N-stearoylethanolamine (18:0 NAE) are structurally related to the endocannabinoid anandamide (20:4 NAE), but these lipids are poor ligands at cannabinoid CB1 receptors. Anandamide is also an activator of the transient receptor potential (TRP) v
Aims: This study looked at whether oral desmopressin, by decreasing kidney urine production, would prolong bladder filling-time thereby increasing the time to reach maximum capacity, thus reducing overactive bladder (OAB) symptoms, and providing an alternative method of treatment to OAB sufferers. Methods: An investigator-initiated, 2-week, multi-national, multi-centre, "proof-of-concept," phase I
The pathogenic yersiniae inject proteins directly into eukaryotic cells that interfere with a number of cellular processes including phagocytosis and inflammatory-associated host responses. One of these injected proteins, the Yersinia protein kinase A (YpkA), has previously been shown to affect the morphology of cultured eukaryotic cells as well as to localize to the plasma membrane following its
Shikimic acid is one of several industrially interesting chiral starting materials formed in the aromatic amino acid pathway of plants and microorganisms. In this study, the physiology of a shikimic acid producing strain of Escherichia coli (derived from W31 10) deleted in aroL (shikimic acid kinase II gene), was compared to that of a corresponding control strain W31 10) under carbonand phosphate-
BACKGROUND AND PURPOSE: Computed tomography (CT) is used to study coronary artery plaques, but little is known about its potential to characterize plaque composition. This study assesses the relation between carotid calcium score (CCS) by CT and plaque composition, namely extracellular matrix, inflammatory mediators, and calcium metabolites. METHODS: Thirty patients with significant carotid sten
Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen bland kvinnor i Sverige. Mer än 7000 kvinnor insjuknar varje år i bröstcancer, och cirka 1500 dör i sjukdomen. Incidensen av bröstcancer har stigit kontinuerligt sedan 1970-talet, och man uppskattar att en av tio kvinnor i Sverige kommer att utveckla bröstcancer någon gång under sin livstid. Den relativa överlevnaden i sjukdomeCancer is a genetic disease that arises when a cell acquires unlimited growth potential through a series of mutational events, which target genes essential for normal cell control and maintenance. Breast cancer is one of the most frequent malignancies in women worldwide, and it is characterized by heterogeneous tumor biology, histological subtypes, variable prognosis and variable responsiveness to
The loss of native riparian vegetation and its replacement with non-native species or grazing land for agriculture is a worldwide phenomenon, but one that is prevalent in Europe, reflecting the heavily-modified nature of the continent's landscape. The consequences of these riparian alterations for freshwater ecosystems remain largely unknown, largely because bioassessment has traditionally focused
We have compared the predictions of ligand-binding affinities from several methods based on end-point molecular dynamics simulations and continuum solvation, i.e. methods related to MM/PBSA (molecular mechanics combined with Poisson-Boltzmann and surface area solvation). Two continuum-solvation models were considered, viz. the Poisson-Boltzmann (PB) and generalised Born (GB) approaches. The non-el
Popular Abstract in Swedish Kraven på bränslesnåla och rena motorer har ökat under de senaste åren. Det började med att priset på olja steg kraftigt i början av 2000-talet. Kraven växte sedan ytterligare i kölvattnet av debatten kring växthuseffekten där koldioxid, en av de dominerande produkterna vid förbränning, spelar huvudrollen. Med tanke på att sänkt bränsleförbrukning rör både ekonomiska ocIn the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). PPC is aimed to provide combustion with low smoke and NOx
Transmitted drug resistance (TDR) is a clinical and epidemiological problem because it may contribute to failure of antiretroviral treatment. The prevalence of TDR varies geographically, and its prevalence in Sweden during the last decade has not been reported. Plasma samples from 1,463 patients newly diagnosed with HIV-1 infection between 2003 and 2010, representing 44% of all patients diagnosed
Pain upon negative pressure wound therapy (NPWT) dressing removal has been reported and is believed to be associ- ated with the observation that granulation tissue grows into foam. Wound tissue damage upon removal of the foam may cause the reported pain. Calcitonin gene-related peptide (CGRP) and substance P are neuropeptides that cause inflam- mation and signal pain and are known to be released w
The aim of this thesis is to describe and analyse Swedish-German contacts in medicine 1933-1945. It shows how the National Socialist German Physicians’ Federation (NSDÄB) tried to strengthen connections with the Swedish medical profession and academic medicine and to spread NS-propaganda to carefully selected Swedish physicians. The dissertation consists of four papers. In the first paper the inte
