Background and purpose - Preoperative posterior tilt of the femoral head as seen on lateral radiographs has been reported to affect the risk of fixation failure in cases of minimally displaced femoral neck fractures (Garden I-II). We investigated radiological risk factors of treatment failure.Patients and methods - We included 417 patients (68% women, median age: 78 years (50-108) with a minimally displaced femoral neck fracture (Garden I-II) treated with internal fixation in a retrospective cohort study. ...

Abstract Mixed ionic-electronic-conducting perovskites such as SrTiO 3 are promising materials to be employed in efficient energy conversion or information processing. These materials exhibit a self-doping effect related to the formation of oxygen vacancies and electronic charge carriers upon reduction. It has been found that dislocations play a prominent role in this self-doping process, serving as easy reduction sites, which result in the formation of conducting filaments along the dislocations. ...

The genus Coccomyxa is frequently present in biological soil crusts from temperate regions but has also been found in Antarctic soils. Strain NIES 2166 (Coccomyxa subellipsoidea) from continental South Victoria Land is described as a model organism for cold adaptation (Blanc et al. 2012) although it has been cultivated for more than 50 years under artificial conditions. In order to test whether this isolate still kept physiological traits for Antarctic conditions or exhibited acclimation/adaptation ...

Members of the cosmopolitan streptophycean genus Klebsormidium live in various habitats, including sand dunes and polar/alpine environments. To survive in these harsh conditions they must possess an array of adaptive physiological and structural mechanisms, for example, to deal with chilling and photochilling stresses. Since these mechanisms have not been studied in detail, the objectives of this study were (i) to determine the physiological and biochemical responses of Klebsormidium cf. flaccidum ( ...

Under the proposed renewables Directive, Member States would commit to delivering additional renewable energy so that collectively they would generate 20% of energy from renewable sources by 2020. The requirements for each Member State are linked to their GDP. The Proposal offers two options for inter–Member State cooperation, based upon the assumption that it may be advantageous to develop additional renewables in countries with good resource basis to meet the target in countries with higher GDP. ...

Background Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are used to prevent ischaemic stroke in patients with stenosis of the internal carotid artery. Better knowledge of risk factors could improve assignment of patients to these procedures and reduce overall risk. We aimed to assess the risk of stroke or death associated with CEA and CAS in patients with different risk factors. Methods We analysed data from 1196 patients randomised to CAS or CEA in the Stent-Protected Angioplasty ...

Chlorella is one of the best‐studied green microalgal genera because of its wide use as a model system and its utilization in biotechnology. Since the description of the type species Chlorella vulgaris Beij., more than a hundred species have been established in the literature. However, the taxonomic description and identification of these small (<15 μm) spherical or elliptical coccoid cells is difficult due to the lack of characteristic morphologic features. In addition to molecular investigations, ...

The role of infection in the pathomechanism of obliterative bronchiolitis (OB) after human lung transplantation is controversial. In a rat lung transplantation model, we analyzed the effect of viral [rat cytomegalovirus (RCMV)] and bacterial infection [Listeria monocytogenes (LM)] on the development of chronic allograft rejection. Fisher rats underwent single left lung transplantation with allografts from Lewis rats. Postoperatively, animals were infected with either RCMV or LM, or served as noninfected ...

Lichens and free-living terrestrial algae are widespread across many habitats and develop successfully in ecosystems where a cold winter limits survival. With the goal of comparing photoprotective responses in free-living and lichenized algae, the physiological responses to chilling and photochilling conditions were studied in three lichens and their isolated algal photobionts together as well as in a fourth free-living algal species. We specifically addressed the following questions: (i) Are there ...

Activation of the platelet membrane receptor glycoprotein (GP) IIb-IIIa is essential for thrombus formation. The novel nonpeptide GPIIb-IIIa antagonist, lamifiban, represents a promising approach for antiplatelet therapy in patients with cardiovascular disease. Since renal impairment frequently occurs in these patients, we designed a phase I study to assess the tolerability, pharmacodynamics and pharmacokinetics of lamifiban in patients with renal impairment. Four healthy volunteers (Group 1) with ...

Abstract Xenotransplantation of pig organs seems a promising way of overcoming the prevailing limitation on allotransplantation due to donor numbers. However, as porcine endogenous retroviruses (PERVs) can infect human cells in vitro, there is substantial concern regarding the risk of a PERV infection in xenogeneic transplant recipients. Cultured porcine endothelial cells, stimulated peripheral blood mononuclear cells, and pancreatic islet cells can release PERV infectious for human cells in vitro, ...

The green microalga Apatococcus lobatus is widely distributed in terrestrial habitats throughout many climatic zones. It dominates green biofilms on natural and artificial substrata in temperate latitudes and is regarded as a key genus of obligate terrestrial consortia. Until now, its isolation, cultivation and application as a terrestrial model organism has been hampered by slow growth rates and low growth capacities. A mixotrophic culturing approach clearly enhanced the accumulation of biomass, ...

The distribution of polyols was examined for the first time in 34 green algal strains from four different clades belonging to the class Trebouxiophyceae, which dominate aeroterrestrial biofilms of many regions. Sorbitol was detected in representatives of the Prasiola clade, while ribitol was present in the Elliptochloris and Watanabea clades. Apatococcus lobatus (Chodat) J. B. Petersen contained erythritol in addition to ribitol. Polyols are considered as effective stress metabolites exerting multiple ...

Maquira coriacea is a commercial tree species growing throughout the Amazon flood plain forests. Densities up to 14/ha of individuals, ≥10 cm diameter at breast height (DBH) were observed, corresponding to a basal area of 2 m2/ha and a volume of 38 m3/ha. The primary period of fruiting coincided with the annual flooding, but fruits were also produced in other parts of the year. Seedlings with densities up to 150/m2 were concentrated around mother trees, and the stocks fluctuated much over the year ...

An established epithelial cell line obtained from 10-day-old rat liver is described. The cytogenic examination revealed a pseudodiploid karyotype with two marker chromosomes. The cells were checked for neoplastic transformation. No transformations occurred within more than two years of subcultivation. Among some enzymes searched for, catalase, 5'-nucleotidase, and catechol-0-methyltransferase activities were detected.

The diffraction pattern reveals a $(1\ifmmode\times\else\texttimes\fi{}1)$ surface structure and LEED intensity versus energy simulations confirm that the crystal is terminated with a Bi bilayer. Excellent agreement is obtained between the calculated and measured diffraction intensities ...

Ellipsoidal Chlorella-like species are very common in all kinds of aquatic and terrestrial habitats, and often identified as Chlorella saccharophila or C. ellipsoidea. However, the taxonomic status of these species remains unclear, because they are not related to the type species of the genus, Chlorella vulgaris. In this study, 23 strains isolated from different habitats, were investigated using a polyphasic approach, i.e. morphology and reproduction, ecophysiology, and combined SSU and ITS rDNA ...
