Background: Osteocalcin (OC) is produced by osteoblasts during bone formation, and circulating OC has been used in clinical investigations as a marker of bone metabolism. OC is excreted into urine by glomerular filtration and can be found in urine as midmolecule fragments. Methods: We developed and evaluated three immunoassays (U-MidOC, U-LongOC, and U-TotalOC) for the detection of various molecul
Objectives: The antibacterial activity of antimicrobial peptides is influenced by various factors such as salt content, pH and the presence of proteins. In this study, we explored the antibacterial action of the human cathelicidin LL-37 in physiologically relevant conditions, i.e. various human wound fluids, human plasma fractions and serum. Methods: Radial diffusion assays using Staphylococcus au
Aims/hypothesis Increased glucagon secretion predicts deterioration of glucose tolerance, and high glucagon levels contribute to hyperglycaemia in type 2 diabetes. Inhibition of glucagon action may therefore be a potential novel target to reduce hyperglycaemia. Here, we investigated whether chronic treatment with a glucagon receptor antagonist (GRA) improves islet dysfunction in female mice on a h
Abstract in German Das systemische klinische Bild der Patienten mit SS kann auf eine Disposition vieler Zellarten zurückgeführt werden, bei einer Konfrontation mit Stressreizen überzureagieren. Dies beeinflusst die elementaren zellulären Vorgänge wie Apoptose und Acethylcholine-Rezeptor-Signalvermittlung. Diese Hyperreaktivität des Gewebes kann auch die beobachteten autoimmunogenen Eigenschaften eThe systemic clinical picture of SS patients can be traced back to a disposition of many cell types to over-react when confronted with stress stimuli. This will influence basic cellular processes such as apoptosis and acetylcholine receptor signaling. This tissue hyper-reactivity may also explain the observed autoimmune features, and may constitute a major aetiopathogenetic determinant in SS.
Aims/Hypothesis: To test the usefulness of the new WHO criteria for clinical staging of diabetes in the characterization of 1977 diabetic patients. Methods: The following clinical stages were used: patients on diet and/or oral antidiabetic agents 2 years after diagnosis were considered as non-insulin requiring (NIR; n = 711) and patients who required insulin therapy after 1 year as insulin requiri
The recent identification of fragile X-associated tremor ataxia syndrome (FXTAS) associated with premutations in the FMR1 gene and the possibility of clinical overlap with multiple system atrophy (MSA) has raised important questions, such as whether genetic testing for FXTAS should be performed routinely in MSA and whether positive cases might affect the specificity of current MSA diagnostic crite
The hottest developments in the fields of cancer research, neuroscience, genomics and proteomics, anti-virals and more, with a pick of the key research papers in these areas.
We report the sequence and expression analysis of two new Drosophila members of the Semaphorin family. Both proteins show the presence of Semaphorin domains and transmembrane domains. Both genes are expressed maternally and in embryos, and reveal distinct expression patterns much earlier than the onset of neurogenesis. We also present an overview of the domain structure of all so far known semapho
The present work deals with the use of a digital thruster (DT) for the separation of cadmium and lead metals from mixture samples. Mixtures of lead and cadmium salts with varying concentrations were injected into a free electrolytic diffusion apparatus (FEDA). The microcathodes surrounding the central anode were programmed witha DT. The DT distributed the charge over the microcathodes at time inte
Human endogenous retroviruses (HERVs) are estimated to represent at least 1% of the human genome. An HERV-H env SU sequence (HERV-H19) was used to screen the high-throughput (htgs) and nonredundant (nr) databases for other HERV-H SU open reading frames (ORFs) and thus possible functional proteins. Using PCR with primers derived from HERV-H19 SU, we also obtained several new sequences with ORFs fro
In 1994, the Malmo-Klaipeda twinning programme was approved by the World Federation of Hemophilia. One of the first steps in the collaboration has been to set up a registry of the haemophilia patients in the Klaipeda area. In order to collect important clinical data the patients have been examined jointly by experts on haemophilia from the two centres. Seventeen out of 25 patients with severe haem
To investigate the relationship between the individual thrombin-cleavages in factor V (FV) and the generation of FXa-cofactor activity, recombinant FV mutants having the cleavage sites eliminated separately or in combination were used. After thrombin incubation, the ability of the FV variants to bind FXa and support prothrombin activation was tested. The interaction between FVa and FXa on the surf
Objective: To determine whether the polymorphisms in aryl hydrocarbon receptor (AHR), aryl hydrocarbon receptor repressor (AHRR), and aryl hydrocarbon receptor nuclear translocator (ARNT) genes are associated with male factor infertility. Design: An association study. Setting: University research laboratory and andrology clinic. Patient(s): The subjects were infertile Estonian men (n = 112) with a
Cyclooctene (C8H14, cot) complexes of platinum(II) have been synthesised and characterised by means of multinuclear NMR, UV-Vis spectroscopy and X-ray crystallography. The bridge-splitting equilibrium constants of the dinuclear, chloride-bridged trans-[PtCl2(cot)]2, 1, in dichloromethane solvent at 298 K with MeOH, MeCN and cot, yielding trans-[PtCl2(cot)(MeOH)], 2, trans-[PtCl2(cot)(MeCN)], 3, an
Background: High-risk alcohol consumption among university students is well documented. Several types of intervention have proved to be effective in reducing alcohol consumption. This study examines the 2-year outcome of 2 different alcohol intervention programs at university halls of residence. Methods: Ninety-eight university halls of residence (with 556 students) were cluster randomized to 2 d
Toll-like receptor 9 (TLR9) induces an inflammatory response by recognition of unmethylated CpG dinucleotides, mainly present in prokaryotic DNA. So far, TLR9-deficient mice have been shown to be more sensitive than wild-type mice to viral, but not to bacterial infections. Here, we show that mice deficient in TLR9 but not in TLR1, TLR2, TLR4 and TLR6 or IL-1R/IL-18R are more susceptible to a respi
OBJECTIVE: To analyse the frequency of autopsy-proven venous thromboembolism within a defined region and evaluate if certain risk groups not earlier recognized could be found. The incidence of objectively diagnosed venous thromboembolism was also calculated. SETTING: The city of Malmo, Sweden, with 230,000 inhabitants. MAIN OUTCOME MEASURE: Analysis of 2,356 autopsies for the year 1987 of deceased
