Different affinity of galectins for human serum glycoproteins: galectin-3 binds many protease inhibitors and acute phase proteins.

Here we report the first survey of galectin binding to glycoproteins of human serum. Serum was subjected to affinity chromatography using immobilized galectins, and the bound glycoproteins were analyzed by electrophoresis, Western blotting, and mass spectrometry. Galectins-3, -8 and -9 bound a much broader range of ligands in serum than previously known, galectin-1 bound less, and galectins-2, -4

Joint Fundamental Frequency and Order Estimation using Optimal Filtering

Abstract in UndeterminedIn this paper, the problem of jointly estimating the number of harmonics and the fundamental frequency of periodic signals is considered. We show how this problem can be solved using a number of methods that either are or can be interpreted as filtering methods in combination with a statistical model selection criterion. The methods in question are the classical comb filter

Outer Partial Actions and Partial Skew Group Rings

We extend the classical notion of an outer action alpha of a group G on a unital ring A to the case when alpha is a partial action on ideals, all of which have local units. We show that if alpha is an outer partial action of an abelian group G, then its associated partial skew group ring A(star alpha) G is simple if and only if A is G-simple. This result is applied to partial skew group rings asso

DNA gel particles

This review covers recent developments on the topic of DNA gel particles formed in water-water emulsion-type interfaces. A general understanding of interactions between DNA and oppositely charged agents has given us a basis for developing novel DNA-based materials, including gel particles. The association strength, which is tuned by varying the chemical structure of the cationic cosolute, determin

Guideline for the investigation and initial therapy of diarrhea-negative hemolytic uremic syndrome

This guideline for the investigation and initial treatment of atypical hemolytic uremic syndrome (HUS) is intended to offer an approach based on opinion, as evidence is lacking. It builds on the current ability to identify the etiology of specific diagnostic sub-groups of HUS. HUS in children is mostly due to infection, enterohemorrhagic Escherichia coli (EHEC), Shigella dysenteriae type 1 in some

Common variants at 30 loci contribute to polygenic dyslipidemia

Blood low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and triglyceride levels are risk factors for cardiovascular disease. To dissect the polygenic basis of these traits, we conducted genome-wide association screens in 19,840 individuals and replication in up to 20,623 individuals. We identified 30 distinct loci associated with lipoprotein concentrations (each

New pulsating white dwarfs in cataclysmic variables

The number of discovered non-radially pulsating white dwarfs (WDs) in cataclysmic variables (CVs) is increasing rapidly by the aid of the Sloan Digital Sky Survey (SDSS). We performed photometric observations of two additional objects, SDSS J133941.11+484727.5 (SDSS 1339), independently discovered as a pulsator by Gansicke et al., and SDSS J151413.72+454911.9, which we identified as a CV/ZZ Ceti h

The effect of protamine sulphate on plasma tissue factor pathway inhibitor released by intravenous and subcutaneous unfractionated and low molecular weight heparin in man

Heparin, a negatively charged sulphated glycosaminoglycan, is clinically the most important antithrombotic drug. Heparin augments the inhibitory activity of antithrombin (AT) towards thrombin, factor Xa (FXa) and other activated clotting enzymes. Tissue factor pathway inhibitor (TFPI) is an endogenous heparin releasable three domain Kunitz-type coagulation inhibitor which inhibits the crucial tiss

Leukotriene B-4 plays a pivotal role in CD40-dependent activation of chronic B lymphocytic leukemia cells

Blosynthesis of leukotrienes (LTs) occurs in human myeloid cells and B lymphocytes. However, the function of leukotrienes in B lymphocytes is unclear. Here, we report that B-cell chronic lymphocytic leukemia (B-CLL) cells produce leukotriene B-4, and that specific leukotriene biosynthesis inhibitors counteracted CD40-dependent activation of B-CLL cells. Studies on the expression of the high-affini

Metapopulation pollination in the deceptive orchid Anacamptis pyramidalis

Pollen dispersal between local plant populations within a range of 6 kin in a geographically defined metapopulation of the lepidopteran-pollinated deceptive orchid Anacamptis pyramidalis was studied on the island Oland in the Baltic Sea. Local A. pyramidalis populations were examined for pollinators, flowering individuals, and fruit set. Population sizes of pollen vector species were estimated usi

Application of the PIV technique to measurements around and inside a forming drop in a liquid–liquid system

A particle image velocimetry (PIV) method has been developed to measure the velocity field inside and around a forming drop with a final diameter of 1 mm. The system, including a microscope, was used to image silicon oil drops forming in a continuous phase of water and glycerol. Fluorescent particles with a diameter of 1 μm were used as seeding particles. The oil was forced through a 200 μm diamet

Feedback control of cerebellar learning

The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. However, except in a metaphorical sense, the cerebellum, which consists of a set of interco

Synthesis of carbon nanotubes on FexOy doped Al2O3-ZrO2 nanopowder

Carbon nanotubes (CNTs) were synthesized on liquid flame sprayed (LFS) powder substrate of iron oxide doped Al2O3-ZrO2. Iron oxide doped Al2O3-ZrO2 nanopowder was produced by injecting the liquid precursor of aluminium-isopropoxide, zirconium-n-propoxide, ferrocene and p-xylene into a high temperature (similar to 3000 K) flame. The precursor solution was atomized by high-velocity H-2 flow and inje

Paradoxes of authentic leadership: Leader identity struggles

Using in-depth interview material, this article explores the socially constructed and locally mediated nature of authentic leadership. The findings illustrate an irony of authentic leadership: while leaders claim that it is their true and natural selves that make them good leaders; simultaneously, they must restrain their claimed authenticity in order to be perceived as good leaders. This generate

The E3 ligase Itch and deubiquitinase Cyld act together to regulate Tak1 and inflammation

Chronic inflammation has been strongly associated with tumor progression, but the underlying mechanisms remain elusive. Here we demonstrate that E3 ligase Itch and deubiquitinase Cyld formed a complex via interaction through 'WW-PPXY' motifs. The Itch-Cyld complex sequentially cleaved Lys63-linked ubiquitin chains and catalyzed Lys48-linked ubiquitination on the kinase Tak1 to terminate inflammato

A simple and versatile implicit solvent model for polyethylene glycol in aqueous solution at room temperature

We present a very simple polymer model of polyethylene glycols/oxides in water that can be used in combination with Molecular Dynamics or Monte Carlo simulations to accurately reproduce the equation of state and radii of gyrations across several orders of magnitude, in terms of osmotic pressure and polymer length. This is of importance for example in osmotic stress experiments, with the aim to acc
