Conformational differences in liganded and unliganded states of Galectin-3

The conformation of the carbohydrate recognition domain of Galectin-3, a lectin known to bind galactose containing oligosaccharides in mammalian systems, has been investigated in the absence of ligand and in the presence of N-acetylactosamine. A new methodology based on the measurement of residual dipolar couplings from NMR spectra has been used to characterize differences in protein structure alo

The effect of platelets on fibrin gel structure formed in the presence of recombinant factor VIIa in hemophilia plasma and in plasma from a patient with Glanzmann thrombasthenia

Fibrin gel structure has been shown to be dependent on the thrombin concentration as well as the rate of thrombin generation. Accordingly, factor VIII (FVIII)and FIX-deficient plasma (hemophilia A and B) form loose fibrin clots with high permeability constants. By adding rFVIIa in vitro to FVIII-deficient plasma containing platelets (frozen and thawed), the fibrin gel permeability constant normali

Temporal and spectral studies of high-order harmonics generated by polarization-modulated infrared fields

The temporal confinement of high harmonic generation (HHG) via modulation of the polarization of the fundamental pulse is studied in both temporal and spectral domains. In the temporal domain, a collinear cross-correlation setup using a 40 fs IR pump for the HHG and a 9 fs IR pulse to probe the generated emission is used to measure the XUV pulse duration. The observed temporal confinement is found

Dual-broadband rotational CARS modelling of nitrogen at pressures up to 9 MPa. I. Inter-branch interference effect

An improved model for pure rotational coherent anti-Stokes Raman scattering (CARS) has been developed or the dual-broadband approach. This model takes into account the fact that coherent anti-Stokes as well as Stokes radiation are generated simultaneously, and these two branches overlap and interact at high pressures giving rise to an inter-branch interference effect. In combustion studies, the an

Confidentiality for adolescents seeking reproductive health care in Lithuania: The perceptions of general practitioners

Confidentiality is a major determinant of the accessibility and acceptability of sexual and reproductive health care for adolescents. Previous research has revealed that Lithuanian adolescents lack confidence in guarantees of confidentiality in primary health care settings. This study aimed to assess the factors that affect general practitioners' decisions whether to respect confidentiality for Li

The role of MRI of the brain and spinal cord, and CSF examination for the diagnosis of primary progressive multiple sclerosis

The clinical applicability of the revised McDonald diagnostic criteria of primary progressive multiple sclerosis (PPMS) was assessed in 17 patients with a longstanding PPMS diagnosis (mean 15 years). All patients were re-evaluated with clinical examinations, magnetic resonance imaging (MRI) of the brain and the spinal cord, extensive laboratory tests, and 12 patients underwent cerebrospinal fluid

Suppression of hadrons with large transverse momentum in central Au+Au collisions at root s(NN)=130 GeV

Transverse momentum spectra for charged hadrons and for neutral pions in the range 1 Gev/c < P-T < 5 GeV/c have been measured by the PHENIX experiment at RHIC in Au + Au collisions at rootS(NN) = 130 GeV. At high p(T) the spectra from peripheral nuclear collisions are consistent with scaling the spectra from p + p collisions by the average number of binary nucleon-nucleon collisions. The spectra f

A microarray for large-scale genomic and transcriptional analyses of the zebra finch (Taeniopygia guttata) and other passerines

The microarray technology has revolutionized biological research in the last decade. By monitoring the expression of many genes simultaneously, microarrays can elucidate gene function, as well as scan entire genomes for candidate genes encoding complex traits. However, because of high costs of sequencing and design, microarrays have largely been restricted to a few model species. Cross-species mic

Suppressed kindling epileptogenesis and perturbed BDNF and TrkB gene regulation in NT-3 mutant mice

In the kindling model of epilepsy, repeated electrical stimulations lead to progressive and permanent intensification of seizure activity. We find that the development of amygdala kindling is markedly retarded in mice heterozygous for a deletion of the neurotrophin-3 (NT-3) gene (NT-3+/- mice). These mice did not reach the fully kindled state (3rd grade 5 seizure) until after 28 +/- 4 days of stim

Comparison of diafiltration and size-exclusion chromatography to recover hemicelluloses from process water from thermomechanical pulping of spruce

Hemicelluloses constitute one of the most abundant renewable resources on earth. To increase their utilization, the isolation of hemicelluloses from industrial biomass side-streams would be beneficial. A method was investigated to isolate hemicelluloses from process water from a thermomechanical pulp mill. The method consists of three steps: removal of solids by microfiltration, preconcentration o

Assessment of regional cerebral blood flow by dynamic susceptibility contrast MRI using different deconvolution techniques

Regional cerebral blood flow (rCBF) was assessed using dynamic susceptibility-contrast MRI at 1.5 T. A simultaneous dual FLASH pulse sequence and Gd-DTPA-BMA (0.3 mmol/kg b.w.) were used for examination of 43 volunteers, measuring rCBF in frontal white matter (WM) and in gray matter in the thalamus (GM). Arterial input functions (AIFs) were registered 1) in the carotid artery and 2) in an artery w

Rethinking Scandinavian Verb Movement

This paper reconsiders the distribution of verb movement in Scandinavian in light of new data from Norwegian and Icelandic. The main claim is that Regional Northern Norwegian displays optional verb movement to the inflectional domain, whereas Icelandic has no independent verb movement at all to this domain, contrary to standard assumptions: All verb movement in Icelandic is to the CP domain of the

Energy limitations for spring migration and breeding: the case of brent geese Branta bernicla tracked by satellite telemetry to Svalbard and Greenland

Brent geese were tracked by satellite telemetry from spring staging areas in Denmark to Arctic breeding areas in Svalbard and Greenland in 1997 and 2001. From estimated departure masses and carcass analysis we used flight mechnical theory to estimate maximum flight ranges of both sexes, and remaining stores of fat and protein upon arrival in females. Model predictions suggested that all birds but

On the role of language constructs for framework design

The relationship between framework design and language constructs are discussed for two reasons: firstly, designing frameworks requires the ability to give the framework designer precise control over aspects of the framework extensions; secondly, the framework constraints should be specified such that they are statically checkable. Four existing language constructs are discussed: generalized block

Life cyle and sexuality of the freshwater raphidophyte Gonyostomum semen (Raphidophyceae)

Previously unknown aspects in the life cycle of the freshwater flagellate Gonyostomum semen (Ehrenb.) (Raphidophyceae) are described here. This species forms intense blooms in many northern temperate lakes, and has increased in abundance and frequency in northern Europe during the past decades. The proposed life cycle is based on observations of life cycle stages and transitions in cultures. Viabl

Heparan sulfate proteoglycans are critical for the organization of the extracellular distribution of Wingless

Recent studies in Drosophila have shown that heparan sulfate proteoglycans (HSPGs) are required for Wingless (Wg/Wnt) signaling. In addition, genetic and phenotypic analyses have implicated the glypican gene daily in this process. Here, we report the identification of another Drosophila glypican gene, daily-like (dly) and show that it is also involved in Wg signaling. Inhibition of dly gene activi
