Postoperative aphakia in modern cataract surgery - Part 2: Detailed analysis of the cause of aphakia and the visual outcome

Purpose: To study the incidence of aphakia after cataract surgery, the surgical complications that can lead to it, and the visual outcome. Setting: Six community-run eye clinics participating in the Swedish National Cataract Register. Methods: Data on cataract extractions were collected prospectively from 1997 through 2001. The data also covered the type of surgery and type of intraocular lens, in

Sensitivity of trapezius electromyography to differences between work tasks - influence of gap definition and normalisation methods

Surface electromyography (EMG) has been used extensively to estimate muscular load in studies of work related musculoskeletal disorders, especially for the trapezius muscle. The occurrences of periods of EMG silence (gaps), the time below a predetermined threshold level (muscular rest) and various percentiles of the amplitude distribution (APDF) are commonly used summary measures. However, the eff

Migratory tectonic switching, western Svecofennian orogen, central Sweden: Constraints from U/Pb zircon and titanite geochronology

The Forsmark area, in the western part of the Svecofennian orogen, central Sweden, is situated between two major Palaeoproterozoic tectonic domains that show contrasting histories with respect to timing of igneous activity, ductile deformation and metamorphism. Geological features common to both the adjacent domains are found at Forsmark, which, consequently, is a key area for understanding the te

Intraclonal variation in defence substances and palatability: a study on Carex and lemmings

Clonal sedges consist of integrated ramets at different development stages. Many of these sedges are important food for herbivores, yet differences in herbivore preferences and defence allocation between ramet development stages have not previously been evaluated. In this study we investigated intraclonal ramet variation in level of plant defence and nutrient compounds and intraclonal ramet prefer

Nitrogen and phosphorus in mire plants: variation during 50 years in relation to supply rate and vegetation type

Southern Sweden has long been exposed to an increasing atmospheric nitrogen deposition. We investigated the effects of this supply on the Sphagnum mire vegetation in SW Gotaland by comparing above-ground tissue concentrations of N and P and biomass variables in five vascular plant and two Sphagnum species collected during three periods since 1955 at 81 sites representing three vegetation types, vi

Monitoring the production of inclusion bodies during fermentation and enzyme-linked immunosorbent assay analysis of intact inclusion bodies using cryogel minicolumn plates

A novel minicolumn chromatgraphic method to monitor the production of inclusion bodies during fermentation and anenzyme-linked immunosorbent assay (ELISA) system allowing direct analysis of the particles with surface-displayed antigens are described. A 33-kDa protein containing 306 amino acids with three sulfur bridges produced its inclusion bodies wits labeled with polyclonal antibodies against 1

Activated porcine embryonic brain endothelial cells induce a proliferative human T-lymphocyte response

Transplantation of allogeneic embryonic neural tissue is a potential treatment for patients with Parkinson's and Huntington's diseases. The supply of human donor tissue is limited, and alternatives such as the use of animal (e.g., porcine) donor tissue are currently being evaluated. Before porcine grafts can be used clinically, strategies to prevent neural xenograft rejection must be developed. Kn

Structure and Bonding of Ethylene Oxide on Si(100)

The bonding configuration and electronic structure of ethylene oxide adsorbed on Si(100)-(2 x 1) is investigated with fully polarization resolved X-ray absorption spectroscopy as well as with core level and valence band photoemission spectroscopy. Ethylene oxide is found to adsorb via a ring-opening reaction, where the molecule forms a five-membered ring together with the silicon surface dimer ato

Oxidation Catalysis on YBa2Cu3O6 + x

Mild oxidation catalysts are used to product a wide range industrial chemicals from hydrocarbons, whereas deep oxidation catalysts yield CO2 and are becoming important in the cleaning of emissions from combustion of carbonaceous fuels. Here we report on a catalyst1 that facilitates both mild and deep oxidation of toluene in the presence of molecular oxygen and ammonia. At low partial pressures of

Resonant photoemission study of La1-xSrxMnO3 single crystals

A feature at a binding energy of similar to 2.5eV which has not previously been discussed in the literature is observed in the photoemission spectra of the valence band of La1-xSrxMnO3 single crystals. To reveal the origin of this feature measurements of resonant photoemission on La1-xSrxMnO3 were performed as well as absorption spectra at the La N and Mn L-2,L-3 edges at liquid nitrogen and room

Crystal structure and biological implications of a bacterial albumin binding module in complex with human serum albumin

Many bactericide species express surface proteins that interact with human serum albumin (HSA). Protein PAB from the anaerobic bacterium Finegoldia magna ( formerly Peptostreptococcus magnus) represents one of these proteins. Protein PAB contains a domain of 53 amino acid residues known as the GA module. GA homologs are also found in protein G of group C and G streptococci. Here we report the crys

Carbon-Phosphorus Bond Activation of Tri(2-thienyl)phosphine at Dirhenium and Dimanganese Centers

Reaction of [Re-2(CO)(9)(NCMe)] with tri(2-thienyl)phosphine (PTh3) in refluxing cyclohexane affords three substituted dirhenium complexes: [Re-2(CO)(9)(PTh3)] (1), [Re-2(CO)(8)(NCMe)(PTh3)] (2), and [Re-2(CO)(8)(PTh3)(2)] (3). Complex 2 was also obtained from the room-temperature reaction of [Re-2(CO)(8)(NCMe)(2)] with PTh3 and is an unusual example in which the acetonitrile and phosphine ligands

Electrochemical characterization and redox behavior of Nb-doped SrTiO3

Sr-vacancy compensated Nb-doped SrTiO3 with the nominal composition Sr0.94Ti0.9Nb0.1O3 has been evaluated as a solid oxide fuel cell (SOFC) anode material in terms of redox stability and electrochemical properties. Sr0.94Ti0.9Nb0.1O3 has been synthesized with a recently developed modified glycine-nitrate process. The phase purity and redox behavior have been analyzed with XRD and TGA. The electroc
