Left atrioventricular plane displacement but not left ventricular ejection fraction is influenced by the degree of aortic stenosis.

Abstract in UndeterminedAims: To examine how left atrioventricular plane displacement ( AVPD), a widely used measure of left ventricular (LV) function, is related to presence and degree of aortic stenosis. Methods and results: Cardiac dimensions, LV filling, left AVPD, LV ejection fraction (LVEF), and valve function were assessed by echocardiography/Doppler in 182 patients with various cardiac dis

Measurement of the He3(e,e'p)pn reaction at high missing energies and momenta

Results of the Jefferson Lab Hall A quasielastic 3He(e,ep)pn measurements are presented. These measurements were performed at fixed transferred momentum and energy, q=1502 MeV/c and =840 MeV, respectively, for missing momenta pm up to 1 GeV/c and missing energies in the continuum region, up to pion threshold; this kinematic coverage is much more extensive than that of any previous experiment. The

Energy conservation and pomeron loops in high energy evolution

We present a formalism which modifies the Mueller Dipole Model such that it incorporates energy-momentum conservation as well as important colour suppressed effects in the cascade evolution. The formalism is implemented in a Monte Carlo simulation program, and the results are compared to inclusive data from HERA and the Tevatron. We here find a generally very good agreement between our model and t

Size and Structure Characterization of Ethylhydroxyethyl Cellulose by the Combination of Field-Flow Fractionation with Other Techniques. Investigation of Ultralarge Components

Ethylhydroxyethyl cellulose (EHEC) of three different viscosity classes (EHEC I, II, and III) was analyzed by programmed cross-flow asymmetrical flow field-flow fractionation coupled to multiangle light scattering and refractive index detectors to determine their size and molar mass distribution. Two size populations were detected in the two lower viscosity classes, EHEC I and II, one high molar m

Bird hosts, blood parasites and their vectors - associations uncovered by molecular analyses of blackfly blood meals.

The level of host specificity of blood-sucking invertebrates may have both ecological and evolutionary implications for the parasites they are transmitting. We used blood meals from wild-caught blackflies for molecular identification of parasites and hosts to examine patterns of host specificity and how these may affect the transmission of avian blood parasites of the genus Leucocytozoon. We found

C1q Inhibits Immune Complex-Induced Interferon-alpha Production in Plasmacytoid Dendritic Cells A Novel Link Between C1q Deficiency and Systemic Lupus Erythematosus Pathogenesis

Objective. C1q deficiency is the strongest risk factor known for the development of systemic lupus erythematosus (SLE), since almost all humans with a genetic deficiency of C1q develop this disease. Low C1q serum concentration is also a typical finding in SLE during flares, emphasizing the involvement of C1q in SLE pathogenesis. Recent studies have revealed that C1q has a regulatory effect on Toll

Molecular Population Genetics of the SRK and SCR Self-incompatibility Genes in the Wild Plant Species Brassica cretica (Brassicaceae).

Self-incompatibility (SI) in plants is a classic example of a trait evolving under strong frequency-dependent selection. As a consequence, population genetic theory predicts that the S locus, which controls SI, should maintain numerous alleles, display a high level of nucleotide diversity, and, in structured populations, show a lower level of among-population differentiation compared to neutral lo

Long-Term Stroke Prognosis in Relation to Medical Prevention and Lifestyle Factors. A Prospective Population-Based Study.

Background: Few studies have focused on the quality of secondary prevention among long-term stroke survivors. This study explores the intensity of medical intervention and the impact of lifestyle and other risk factors on the long-term stroke prognosis in a population-based setting of Swedish individuals with a history of stroke. Methods: A population-based cohort (n = 28,449) in Malmo, Sweden, wa

Furongian (upper Cambrian) biostratigraphy and trilobites of the Haslov-1 drill core, Scania, S. Sweden

A drilling made in 1972 at Haslov, Scania, southern Sweden, penetrated a 2572 m thick succession of Phanerozoic strata. The only cored parts of the succession derive from the Upper Ordovician and the Furongian (upper Cambrian) series. Merely the uppermost part of the Furongian was recovered, comprising eight metres of Alum Shale with limestone concretions. Nine species and subspecies of trilobites

Photochemical reactivity of aquatic macrophyte leachates: abiotic transformations and bacterial response

We evaluated the influence of UV radiation exposure time on abiotic transformations of leachates from 2 aquatic macrophytes: Phragmites australis and Hydrocaris morsus-ranae. In addition, we studied the influence of phototransformations of DOM on bacterial growth. Sterile filtered leachates were exposed to UV radiation for 5, 10, 24, 48, 72 and 120 h or kept in the dark. Dissolved inorganic carbon

Hematopoietic stem cell responsiveness to exogenous signals is limited by Caspase-3

Limited responsiveness to inflammatory cytokines is a feature of adult hematopoietic stem cells and contributes to the relative quiescence and durability of the stem cell population in vivo. Here we report that the executioner Caspase, Caspase-3, unexpectedly participates in that process. Mice deficient in Caspase-3 had increased numbers of immunophenotypic long-term repopulating stem cells in ass

Regionalization and fate specification in neurospheres: the role of Olig2 and Pax6

Neurosphere cultures are widely used to propagate multipotent CNS precursors, but their differentiation into neurons or oligodendrocytes is rather poor. To elucidate fate determination in this system, we examined the expression and function of candidate transcription factors in neurospheres derived from different CNS regions during development and adulthood. We observed prominent down-regulation o

ACTH reduces the rise in ApoB-48 levels after fat intake.

It has been repeatedly demonstrated that ACTH administration lowers plasma lipid concentrations in man. The present study was designed to test the hypothesis, based on observations of decreased apolipoprotein B (ApoB) synthesis and secretion in vitro, that ACTH administration inhibits the postprandial output of ApoB in man. Therefore, we studied the response to a fat-rich meal supplemented with Vi

Clinical system for interstitial photodynamic therapy with combined on-line dosimetry measurements

A system for interstitial photodynamic therapy with delta-aminolaevulinic acid and multiple optical fibers has been developed. The system enables photodynamic treatment of large embedded tumor volumes and utilizes real-time measurements to allow on-line dosimetry. Important parameters such as light fluence rate, sensitizer fluorescence intensity, and changes in local blood oxygen saturation are me

Tissue and intracellular pH in normal periarticular soft tissue and during different phases of antigen induced arthritis in the rat

OBJECTIVE: To measure intracellular and tissue pH in periarticular soft tissue during different phases of antigen induced arthritis in the rat. METHODS: pH was calculated using the following values: (1) the distribution of [14C]-dimethyl-oxazolidinedione; (2) the total tissue water and the extracellular space water volume, which was measured as [14C]-sucrose distribution in nephrectomized rats.
