Influence of systemic bisphosphonate treatment on mechanical properties of BMP-induced calluses in a rat fracture model: Comparison of three-point bending and twisting test.

The combination of autograft, BMP and bisphosphonate has been shown to produce strong calluses. In this study, without autograft we investigate the effect of bisphosphonate treatment on BMP-induced calluses, both in bending and in rotation. Sprague-Dawley rats (n = 42) underwent femoral osteotomy and BMP-7 treatment. At 2 weeks an injection of saline or bisphosphonate was administered. The animals

Tunable mega-ampere electron current propagation in solids by dynamic control of lattice melt.

The influence of lattice-melt-induced resistivity gradients on the transport of mega-ampere currents of fast electrons in solids is investigated numerically and experimentally using laser-accelerated protons to induce isochoric heating. Tailoring the heating profile enables the resistive magnetic fields which strongly influence the current propagation to be manipulated. This tunable laser-driven p

The compression anastomotic ring-locking procedure : a novel technique for creating a sutureless colonic anastomosis

BACKGROUND/AIM: Compression anastomoses might represent an improvement over traditional hand-sewn or stapled techniques. Herein, we describe a novel concept of sutureless colonic anastomosis named compression anastomotic ring-locking procedure (CARP).MATERIALS AND METHODS: The surgical device consists of two anastomotic rings and their associated helping tools, facilitating the placement of the ri

Palynological perspectives on vegetation survey: a critical step for model-based reconstruction of Quaternary land cover

1. Quantitative reconstruction of past vegetation distribution and abundance from sedimentary pollen records provides an important baseline for understanding long term ecosystem dynamics and for the calibration of earth system process models such as regional-scale climate models, widely used to predict future environmental change. Most current approaches assume that the amount of pollen produced b

The molecular basis of iron-induced oligomerization of frataxin and the role of the ferroxidation reaction in oligomerization.

The role of the mitochondrial protein frataxin in iron storage and detoxification, iron delivery to iron-sulfur cluster biosynthesis, heme biosynthesis and aconitase repair has been extensively studied during the last decade. However, still no general consensus exists on the details of the mechanism of frataxin function and oligomerization. Here, using small-angle X-ray scattering (SAXS) and X-ray

MegaGauss magnetic field generation by ultra-short pulses at relativistic intensities

We report the experimental studies on megaGauss magnetic field generation using a 35 femtosecond laser at relativistic intensities. The polarization change of the self-generated harmonics was recorded to estimate the magnetic field. A parameter scan was performed by varying the input laser intensity as well as the contrast ratio. External optical probing diagnostics were performed using the second

Search for pair-produced third-generation squarks decaying via charm quarks or in compressed supersymmetric scenarios in pp collisions at root s = 8 TeV with the ATLAS detector

Results of a search for supersymmetry via direct production of third-generation squarks are reported, using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded by the ATLAS experiment at the LHC in 2012. Two different analysis strategies based on monojetlike and c-tagged event selections are carried out to optimize the sensitivity for direct top squark-pair production in the dec

Förster resonance energy transfer studies of calmodulin produced by native protein ligation reveal inter-domain electrostatic repulsion.

This study explores the influence of long-range intra-protein electrostatic interactions on the conformation of calmodulin in solution. Ensemble Förster resonance energy transfer (FRET) is measured for calmodulin with a fluorophore pair incorporated specifically with a donor at residue 17 and an acceptor at position 117. This construct was generated by a combination of solid phase peptide synthesi

Materialist/postmaterialist values and their association with psychological health and health locus of control: A population-based study

This study investigates the association between Ronald Inglehart's materialist/postmaterialist index, a psychological aspect of the material pathway to inequalities in health, and health locus of control and psychological health. The data used is from the 2008 public health survey in Skane, a cross-sectional postal questionnaire study with 28,198 respondents (response rate 54%), conducted in south

Stage-Specific Modulation of Cortical Neuronal Development by Mmu-miR-134

To realize the potential of microRNAs (miRs) as fine-tuning regulators of embryonic neuronal differentiation, it is critical to define their developmental function. Mmu-miR-134 (miR-134) is a powerful inducer of pluripotent stem cell differentiation. However, its functional role during embryonic, neuronal development is unknown. We demonstrate that mature, miR-134 transcript levels elevate during

LaCoO3: Promising cathode material for protonic ceramic fuel cells based on a BaCe0.2Zr0.7Y0.1O3-delta electrolyte

Symmetric cells (cathode/electrolyte/cathode) were prepared using BaCe0.2Zr0.7Y0.1O3-delta (BCZY27) as proton conducting electrolyte and LaCoO3 (LC) infiltrated into a porous BCZY27 backbone as cathode. Single phased LC was formed after annealing in air at 600 degrees C for 2 h. Scanning electron micrographs showed the presence of the infiltrated LC in the full cathode depth. Transmission electron

Multifaceted role of the ubiquitin ligase Itch in immune regulation.

The HECT-type E3 ligase Itch is increasingly being shown to have a vital role in immune regulation. Itch deficiency leads to deleterious inflammatory disorders both in mice and humans. By adding ubiquitin to the key signaling intermediates, Itch functions as a critical regulator of lymphocyte-cell activation, differentiation and immune tolerance. Also, Itch cooperates with deubiquitinating enzymes

An abundance of small exoplanets around stars with a wide range of metallicities

The abundance of heavy elements (metallicity) in the photospheres of stars similar to the Sun provides a 'fossil' record of the chemical composition of the initial protoplanetary disk. Metal-rich stars are much more likely to harbour gas giant planets(1-4), supporting the model that planets form by accumulation of dust and ice particles(5). Recent ground-based surveys suggest that this correlation

Memory trace and timing mechanism localized to cerebellar Purkinje cells

The standard view of the mechanisms underlying learning is that they involve strengthening or weakening synaptic connections. Learned response timing is thought to combine such plasticity with temporally patterned inputs to the neuron. We show here that a cerebellar Purkinje cell in a ferret can learn to respond to a specific input with a temporal pattern of activity consisting of temporally speci

The Fitch-Church Paradox and First Order Modal Logic

Reformulation strategies for solving Fitch’s paradox of knowability date back to Edgington. Their core assumption is that the formula \ , from which the paradox originates, does not correctly express the intended meaning of the verification thesis , which should concern possible knowledge of actual truths, and therefore the contradiction does not represent a logical refutation of verificationism.

Returning to a changed ordinary life - families' lived experience after completing a child's cancer treatment

The aim of the study was to illuminate the families' lived experience after completing a child's cancer treatment. The study took place at a University Hospital in southern Sweden. Interviews were carried out with 10 mothers, eight fathers, four patients and two siblings from a total of 10 families. The interviews were analysed with a hermeneutical phenomenological approach. One essential theme em
