Purpose. When performing perimetry, refracting subjects with central visual field loss, and in emmetropization studies, it is important to accurately measure peripheral refractive errors. Traditional methods for foveal refraction often give uncertain results in eccentric angles as a result of the large aberrations and the reduced retinal function. The aim of this study is therefore to compare and

Aim: To explore the association between the coagulation protein fibrinogen and the fibrinolytic biomarker plasminogen activator inhibitor-1 ( PAI- 1) and the long- term mortality after coronary artery bypass grafting ( CABG). Patients and Methods: In 729 patients undergoing CABG at Sahlgrenska University Hospital, a blood sample for fibrinogen and PAI-1 was collected prior to the procedure. Patien

Our main result gives necessary and sufficient conditions, in terms of Fourier transforms, for an ideal in the algebra L-1(G parallel to K, omega), the convolution algebra of zonal functions on the automorphism group on the unit disc which are integrable with respect to the weight; function omega, to be dense in the algebra, or to have as closure an ideal of functions whose set of common zeros of

We present first results of three-dimensional numerical simulations ofthe non-magnetic solar chromosphere, computed with the radiationhydrodynamics code CO5BOLD. Acoustic waves which are excitedat the top of the convection zone propagate upwards into thechromosphere where the waves steepen into shocks. The interaction of thewaves leads to the formation of complex structures which evolve on shortti

The thermophilic marine bacterium Rhodothermus marinus produces a modular family 10 xylanase (Xyn10A). It consists of two N-terminal family 4 carbohydrate binding modules (CBMs) followed by a domain of unknown function (D3), and a catalytic module (CM) flanked by a small fifth domain (D5) at its C-terminus. Several truncated mutants of the enzyme have been produced and characterised with respect t

The Type 1 Diabetes Genetics Consortium (T1DGC), funded September 2002, is a collaborative effort to develop resources for the purpose of identifying risk genes for type 1 diabetes. One of the aims is to establish a renewable resource of DNA on 2500 affected sib-pair families. Regional networks have been established and in continental Europe, the European Type 1 Diabetes Genetics Network (ET1DGN)

Immunization of H2(p) and H2(q) congenic C3H mouse strains with the PLP 103-116 peptide elicited two distinct experimental allergic encephalomyelitis (EAE) disease courses. C3H.Q (H2(q)) mice developed an acute-phase disease with classical ascending paralytic signs whereas C3H.NB (H2(p)) developed a highly variable disease course with symptoms originating from CNS above the spinal chord. C3H.Q lac

Using the combined Golgi-electron microscopy technique, we have determined the three-dimensional dendritic fields of the short visual fibres (svf 1-3) and first-order interneurons or L-fibres (L1-4) within the first optic ganglion (lamina) of the nocturnal bee Megalopta genalis. Serial cross sections have revealed that the svf type 2 branches into one adjacent neural unit (cartridge) in layer A, t

The second coding exon of the adenosine A, receptor gene was eliminated by homologous recombination. The phenotype of mice (mixed C57B6/129OlaHsd background) was studied, using siblings from matings of heterozygous mice. Among the offspring the ratio between+/+, +/-and -/-animals was 1:2:1. Over the first half-year-at least-growth and viability were the same in all genotypes. Binding of A(1) ligan

The dynamics of adsorption and desorption of uncharged homopolymers have been investigated using a coarse-grained model comprised of a bead-spring chain and a planar surface. Brownian dynamics simulation has been used to examine the adsorption process for polymers released near the surface and with bulk properties as well as Monte Carlo simulations to explore equilibrium adsorption structures of t

We prepared a Au/CeO2 (111) model catalyst by depositing a thin cerium oxide film on a Ru(0001) surface and subsequently depositing gold. This model system was investigated using high-resolution photoemission spectroscopy. Gold forms metallic nanoparticles on CeO2 with an average particle size that depends on the Au dose. At 80 K adsorption of CO was observed on the supported Au particles, which i

The subventricular zone (SVZ) is one of the neurogenic regions of the adult brain. We characterized the neurogenic response of the SVZ to the growth of brain tumors in the rat striatum. Abundant nestin positive cells, most likely representing reactive astrocytes, were found surrounding the tumor. However, we observed no substantial migration of nestin positive cells from the SVZ toward the tumor.

A multicentre, randomized, double-blind, crossover study was designed to investigate the effects of prednisone on allergic and irritant patch test reactions. 24 subjects with known allergy to nickel were recruited and patch tested with a nickel sulfate dilution series in aqueous solution, 5% nickel sulfate in petrolatum and 2 dilution series of the irritants nonanoic acid and sodium lauryl sulfate

In factor V (FV) Cambridge (Arg306Thr) and Hong Kong (Arg306Gly), a cleavage site for anticoagulant activated protein C (APC), which is crucial for the inactivation of FVa, is lost. Although patients carrying FV Hong Kong have a normal APC response, those with FV Cambridge were reported to be APC resistant. To elucidate the molecular characteristics of the 2 FV mutants, we recreated them in a reco
