Lipids may serve as coupling factors in KATP-independent glucose sensing in β-cells. We have previously demonstrated that β-cells harbor lipase activities, one of which is the hormone-sensitive lipase. Whether β-cell lipases are critical for glucose-stimulated insulin secretion (GSIS) by providing lipid-derived signals from endogenous lipids is unknown. Therefore, using a lipase inhibitor (orlista
A comparison is made between the development trends experience over the last decades by the steel and papermaking industries, respectively. These two industrial branches, although totally different in their technical nature, are subject to similar pressures from their external environment, notably increasing requirements for environmental protection and more efficient raw material management. Such
The potential modes of transmission for hepatitis C virus (HCV) infections were studied using a multivariate analysis of risk factor exposure among 51 2nd generation anti-HCV and HCV-RNA positive and matched anti-HCV negative blood donors. The following variables were found to be independently associated with anti-HCV and HCV-RNA positivity: intravenous drug use (IVDU) (p < 0.001), blood transfusi
Proteins interacting with the human PDGF (platelet-derived growth factor) b-receptor were isolated using immobilized peptides derived from the receptor C-terminus as a bait. We identified two PDZ domain proteins, namely NHERF (Na+/H+ exchanger regulatory factor, also called EBP50) and NHERF2 (E3KARP, SIP-1, TKA-1), which have been shown previously to associate with the murine PDGF receptor [Maudsl
Seven diterpenoids, isolated due to their ability to inhibit spore germination in the plant pathogenic fungus Magnaporthe grisea, were obtained from cultures of the basidiomycete Coprinus heptenlerus. The structures of the compounds, named heptemerones A-G, were determined with spectroscopic techniques. (c) 2005 Elsevier Ltd. All rights reserved.

Popular Abstract in Swedish Avhandlingen består av fem fristående uppsatser som utnyttjar tidsserieanalys för studerande av några olika makroekonomiska frågor. I kapitel två, tre och fyra används s.k. vektorautoregressiva (VAR) modeller för att studera privat konsumtionsbeteende i Sverige. Enligt den permanenta inkomst hypotesen väljer individerna sin konsumtion med hänsyn till sin långsiktiga ellAdvances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate. Chapter two explores the empirical evi
The angiogenic mechanism and therapeutic potential of PDGF-CC, a recently discovered member of the VEGF/PDGF superfamily, remain incompletely characterized. Here we report that PDGF-CC mobilized endothelial progenitor cells in ischemic conditions; induced differentiation of bone marrow cells into ECs; and stimulated migration of ECs. Furthermore, PDGF-CC induced the differentiation of bone marrow
We report here the identification of a gene associated with the hyperparathyroidism-jaw tumor (HPT-JT) syndrome. A single locus associated with HPT-JT (HRPT2) was previously mapped to chromosomal region 1q25-q32. We refined this region to a critical interval of 12 cM by genotyping in 26 affected kindreds. Using a positional candidate approach, we identified thirteen different heterozygous, germlin
Background: Serial Analysis of Gene Expression (SAGE) is a functional genomic technique that quantitatively analyzes the cellular transcriptome. The analysis of SAGE libraries relies on the identification of ditags from sequencing files; however, the software used to examine SAGE libraries cannot distinguish between authentic versus false ditags ("quasi-ditags"). Results: We provide examples of qu
Little is known concerning possible hazards of maternal use of the recently introduced antidepressant drugs with noradrenergic and varying serotonergic activity (serotonin-noradrenaline reuptake inhibitor [SNRI]/noradrenergic reuptake inhibitor [NRI] drugs). Using the Swedish Medical Birth Registry, we identified 732 women who had used SNRI/NRI drugs in early pregnancy. Maternal characteristics we
In this letter, we present a decomposition for sinusoidal coding of audio, based on an amplitude modulation of sinusoids via a linear combination of arbitrary basis vectors. The proposed method, which incorporates a perceptual distortion measure, is based on a relaxation of a nonlinear least-squares minimization. Rate-distortion curves and listening tests show that, compared to a constant-amplitud
Popular Abstract in Swedish Akut faryngotonsillit orsakas till ca 40 % av betahaemolytiska grupp A streptokocker (GAS) och till ca 10% av andra bakterier. Ca 30% av fallen är virusutlösta och i ca 20% är genesen okänd. GAS är mycket virulenta humanpatogener som förutom svalg- och hudinfektioner även kan förorsaka livshotande tillstånd som ?streptococcal toxic shock syndrome? och nekrotiserande fasIn acute pharyngotonsillitis group A streptococci (GAS) is the etiological agent in 30-50% of cases. Phenoxymethylpenicillin (pcV) is the drug of choice in Sweden. However, the failure rate is as high as 5-25% and further pcV treatment is followed by still higher failure rates. The background of failures remains largely elusive. The aim of the studies was: 1 To investigate the short- and long-term
Medieval watermills: A review of Christian Fischers monograph “Tidlige danske vandmøller. To middelalderlige vandmøller ved Tovstrup og Vejerslev” (Early Danish Watermills. Two medieval watermills at Tovstrup and Vejerslev) from 2004.
To study the absorption, metabolism and kinetics, the AKG ( in different concentrations) was administered intravenously, intra-portally, orally and directly into the ileum or duodenum of pigs, chronically fitted with portal and jugular catheters and T-shaped cannula at the duodenum and ileum. Additionally, this study was conducted to determine the influence of low pH, Fe2+ or/ and SO42- on AKG gut
Microcalorimetry, i.e., the measurement of heat production rate was used to assess the metabolic activity of six wood-decay fungi growing on moist wood particles as a function of the temperature. Four brown-rot fungi increased their activity with increasing temperature in the temperature range 5-35 C, and one brown-rot and the white-rot fungus had a lower activity at 35 C than at 25 C. It may be p
