Paper 6: EUROCAT Member Registries: Organization and Activities
BACKGROUND: EUROCAT is a network of population-based congenital anomaly registries providing standardized epidemiologic information on congenital anomalies in Europe. There are three types of EUROCAT membership: full, associate, or affiliate. Full member registries send individual records of all congenital anomalies covered by their region. Associate members transmit aggregate case counts for each
Serum Fibroblast Growth Factor-23 (FGF-23) and Fracture Risk in Elderly Men
A normal mineral metabolism is integral for skeletal development and preservation of bone integrity. Fibroblast growth factor 23 (FGF-23) is a bone-derived circulating factor that decreases serum concentrations of inorganic phosphorous (P-i) and 1,25-dihydroxyvitamin D-3 [1,25(OH)(2)D-3]. Increased FGF-23 expression is a direct or indirect culprit in several skeletal disorders; however, the relati
Role of Deprotonation and Cu Adatom Migration in Determining the Reaction Pathways of Oxalic Acid Adsorption on Cu(111)
Scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and first principles theoretical calculations have been used to gain insight into the fundamental processes involved in the adsorption and self-assembly of oxalic acid on Cu(111). The experimental data demonstrate that several reaction pathways are involved in the chemisorption of oxalic acid on Cu(111), one of which lead
Pollinator attraction to volatiles from virgin and pollinated host flowers in a yucca/moth obligate mutualism
The classic obligate pollination–seed consumption mutualism between yuccas and yucca moths has been thought to be mediated by chemical cues, but empirical data on pollinator attraction to host floral volatiles in this association have been lacking. Here we show that the scent from virgin flowers of the host Yucca glauca is sufficient to attract its obligate pollinator Tegeticula yuccasella in Y-tu
The extended evolutionary synthesis: its structure, assumptions and predictions.
Scientific activities take place within the structured sets of ideas and assumptions that define a field and its practices. The conceptual framework of evolutionary biology emerged with the Modern Synthesis in the early twentieth century and has since expanded into a highly successful research program to explore the processes of diversification and adaptation. Nonetheless, the ability of that fram
In-situ characterization of metal nanoparticles and their organic coatings using laser-vaporization aerosol mass spectrometry
The development of methods to produce nanoparticles with unique properties via the aerosol route is progressing rapidly. Typical characterization techniques extract particles from the synthesis process for subsequent offline analysis, which may alter the particle characteristics. In this work, we use laser-vaporization aerosol mass spectrometry (LV-AMS) with 70-eV electron ionization for real-time
Design and Development of Products and Services at the Base of the Pyramid: A Review of Issues and Solutions
Abstract in UndeterminedThe base of the world income pyramid, generally called the ‘Base of the Pyramid’ (BoP), consists of four billion people with average per day income of less than four dollars. Over the past several years, the design and development of products and services at the BoP (BoP people as producers and consumers as well) has been investigated by several authors from different disci
OMERACT Filter Evidence Supporting the Measurement of At-work Productivity Loss as an Outcome Measure in Rheumatology Research.
Indicators of work role functioning (being at work, and being productive while at work) are important outcomes for persons with arthritis. As the worker productivity working group at OMERACT (Outcome Measures in Rheumatology), we sought to provide an evidence base for consensus on standardized instruments to measure worker productivity [both absenteeism and at-work productivity (presenteeism) as w
Strategies for quality assurance of intensity modulated radiation therapy
In late 2011 The Swedish Society of Radiation Physics formed a working group to concentrate on the Quality Assurance of modern radiation therapy techniques. The given task was to identify and summarise the different QA strategies in Sweden and also the international recommendations. This was used to formulate recommendations for practical guidelines within Sweden. In this paper a brief summery of

Prediagnostic telomere length and risk of B-cell lymphoma-Results from the EPIC cohort study
Recent epidemiological investigations have reported on the association between telomere length (TL) and a number of malignancies, including B-cell lymphoma (BCL). The reported results for BCLs are however inconsistent. We carried out a nested case-control study to determine whether TL is associated with future risk of BCL. Using quantitative polymerase chain reaction, the relative TL (i.e. the rat
Extraction of oxide traps in III-V MOSFETs using RF transconductance measurements
We here present simulations of the effect of border traps on the behavior of a III-V FET's transconductance with respect to frequency. We also compare simulations with a recently developed analytical model for extracting the border trap distribution through measurements of the transconductance, find good agreement between the extracted and simulated transconductance.
Covalent immobilization of molecularly imprinted polymer nanoparticles on a gold surface using carbodiimide coupling for chemical sensing.
One challenging task in building (bio)chemical sensors is the efficient and stable immobilization of receptor on a suitable transducer. Herein, we report a method for covalent immobilization of molecularly imprinted core-shell nanoparticles for construction of robust chemical sensors. The imprinted nanoparticles with a core-shell structure have selective molecular binding sites in the core and mul
Activating Women in the Swedish Model
The 1960s marked the beginning of a new era of family and gender relations in Sweden. It was a time when traditional values and ideas concerning the family were questioned and redefined in policymaking. The Women's movement and political radicalization underpinned the emergence of gender equality policy ambitions, culminating in several gender neutral reforms in the 1970s. These policy ambitions c
Impact of Baseline Severity of Aortic Valve Stenosis on Effect of Intensive Lipid Lowering Therapy (from the SEAS Study)
Retrospective studies have suggested a beneficial effect of lipid-lowering treatment on the progression of aortic stenosis (AS) in milder stages of the disease. In the randomized, placebo-controlled Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study, 4.3 years of combined treatment with simvastatin 40 mg and ezetimibe 10 mg did not reduce aortic valve events (AVEs), while ischemic cardiovas
Preparation of protein imprinted polymer beads by Pickering emulsion polymerization
We present a new method for preparation of protein-specific polymer beads based on surface molecular imprinting in Pickering emulsion. In the first step, adult human hemoglobin (Hb) was adsorbed on silica nanoparticles. The protein-coated silica particles were then used to stabilize an oil-in-water emulsion (Pickering emulsion) composed of cross-linking monomer in the oil phase. After free radical
Circulating glycosaminoglycan species in septic shock.
Glycosaminoglycans (GAGs) are negatively charged polysaccharides present, e.g., on the luminal face of the blood vessels as heparan sulphate (HS) and hyaluronic acid (HA), in the interstitium as HA, and in neutrofils and plasma as chondroitin sulphate (CS) and HA. Total plasma levels of GAG are increased in human septic shock, but the origin and pathophysiological implications are unclear. In orde
The YjbH adaptor protein enhances proteolysis of the transcriptional regulator Spx in Staphylococcus aureus.
Spx is a global regulator that is widespread among the low G+C Gram-positive bacteria. Spx has been extensively studied in Bacillus subtilis, where it acts as an activator and a repressor of transcription in response to disulfide stress. Under non-stress conditions, Spx is rapidly degraded by the ClpXP protease. This degradation is enhanced by the YjbH adaptor protein. Upon disulfide stress, the a
Green's function for a spherical dielectric discontinuity and its application to simulation
We present rapidly convergent expressions for the Green's function of the Poisson equation for spherically symmetric systems where the dielectric constant varies discontinuously in the radial direction. These expressions are used in Monte Carlo simulations of various electrolyte systems, and their efficiency is assessed. With only the leading term of the expansion included, a precision of the pola
