Effect of Adenosine on Injury Caused by lschemia and Reperfusion in Rats: Functional and Morphologic Study

To study whether treatment with adenosine (ADO), an agonist of adenosine receptors, attenuates intestinal dysfunction caused by ischemia (I) and reperfusion (R), we treated rats with ADO (15 mg/kg or saline solution (SS) intravenously before 60 minutes occlusion of the superior mesenteric artery (I) and/or 120 minutes after its release (R). After I or I/R, isolated jejunal segments (2 cm) were mounted in an organ bath to study nerve-mediated contractions stimulated by electrical pulses or KCI with the use of a digital recording system. Thin jejunal slices were stained with hematoxylin and eosin for optical microscopy. Compared with the sham group, jejunal contractions were reduced in I+SS and IR+SS but similar after treatment with ADO (I+ADO and IR+ADO groups). We concluded that rat jejunal enteric nerves were damaged in I+SS and IR+SS but not in the I+ADO and IR+ADO groups. These results suggested that ADO attenuated intestinal dysfunction due to I and R.Fed Univ São Paulo UNIFESP, Dept Pharmacol, São Paulo, BrazilFed Univ São Paulo UNIFESP, Dept Biochem, São Paulo, BrazilFed Univ São Paulo UNIFESP, Dept Morphol, São Paulo, BrazilFed Univ São Paulo UNIFESP, Dept Surg, São Paulo, BrazilFed Univ Great Dourados, Sch Med, Dourados, BrazilFed Univ São Paulo UNIFESP, Dept Pharmacol, São Paulo, BrazilFed Univ São Paulo UNIFESP, Dept Biochem, São Paulo, BrazilFed Univ São Paulo UNIFESP, Dept Morphol, São Paulo, BrazilFed Univ São Paulo UNIFESP, Dept Surg, São Paulo, BrazilWeb of Scienc
Modelling of the radio emission from the Vela supernova remnant

Supernova remnants (SNRs) are widely considered to be sites of Galactic cosmic ray (CR) acceleration. Vela is one of the Galactic
composite SNRs closest to Earth accompanied by the Vela pulsar and its pulsar wind nebula (PWN) Vela X. The Vela SNR is one of
the most studied remnants and it benefits from precise estimates of various physical parameters such as distance and age. Therefore,
it is a perfect object for a detailed study of physical processes in SNRs. The Vela SNR expands into the highly inhomogeneous
cloudy interstellar medium (ISM) and its dynamics are determined by the heating and evaporation of ISM clouds. It features an
asymmetrical X-ray morphology, which is explained by the expansion into two media with different densities. This could occur if the
progenitor of the Vela SNR exploded close to the edge of the stellar wind bubble of the nearby Wolf-Rayet star γ2 Velorum causing
one part of the remnant to expand into the bubble. The interaction of the ejecta and the main shock of the remnant with ISM clouds
causes formation of secondary shocks at which additional particle acceleration takes place. This may lead to the almost uniform
distribution of relativistic particles inside the remnant. We calculate the synchrotron radio emission within the framework of the new
hydrodynamical model that assumes the supernova explosion at the edge of the stellar wind bubble. The simulated radio emission
agrees well with both the total radio flux from the remnant and the complicated radio morphology of the sourcehttp://www.aanda.orghttp://dx.doi.org/10.1051/0004-6361/20132256
Summary of the ATLAS experiment's sensitivity to supersymmetry after LHC Run 1-interpreted in the phenomenological MSSM

A summary of the constraints from the ATLAS experiment on R-parity-conserving supersymmetry is presented. Results from 22 separate ATLAS searches are considered, each based on analysis of up to 20.3 fb(-1) of proton-proton collision data at centre-of-mass energies of root s = 7 and 8TeV at the Large Hadron Collider. The results are interpreted in the context of the 19-parameter phenomenological minimal supersymmetric standard model, in which the lightest supersymmetric particle is a neutralino, taking into account constraints from previous precision electroweak and flavour measurements as well as from dark matter related measurements. The results are presented in terms of constraints on supersymmetric particle masses and are compared to limits from simplified models. The impact of ATLAS searches on parameters such as the dark matter relic density, the couplings of the observed Higgs boson, and the degree of electroweak fine-tuning is also shown. Spectra for surviving supersymmetry model points with low fine-tunings are presented.<p>ATLAS Collaboration, for complete list of authors see http://dx.doi.org/10.1007/JHEP10(2015)134</p><p>Funding: We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT and NSRF, Greece; RGC, Hong Kong SAR, China; ISF, MINERVA, GIF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; BRF and RCN, Norway; MNiSW and NCN, Poland; GRICES and FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.</p
Survey on assembly sequencing : a combinatorial and geometrical perspective

A systematic overview on the subject of assembly sequencing is presented. Sequencing lies at the core of assembly planning, and variants include finding a feasible sequence—respecting the precedence constraints between the assembly operations—, or determining an optimal one according to one or several operational criteria. The different ways of representing the space of feasible assembly sequences are described, as well as the search and optimization algorithms that can be used. Geometry plays a fundamental role in devising the precedence constraints between assembly operations, and this is the subject of the second part of the survey, which treats also motion in contact in the context of the actual performance of assembly operations.Peer ReviewedPostprint (published version
The thermoelectric properties of inhomogeneous holographic lattices.

We consider inhomogeneous, periodic, holographic lattices of D = 4 Einstein-Maxwell theory. We show that the DC thermoelectric conductivity matrix can be expressed analytically in terms of the horizon data of the corresponding black hole solution. We numerically construct such black hole solutions for lattices consisting of one, two and ten wave-numbers. We numerically determine the AC electric conductivity which reveals Drude physics as well as resonances associated with sound modes. No evidence for an intermediate frequency scaling regime is found. All of the monochromatic lattice black holes that we have constructed exhibit scaling behaviour at low temperatures which is consistent with the appearance of AdS2×R2 in the far IR at T = 0
Moving contact line dynamics : from diffuse to sharp interfaces.

We reconcile two scaling laws that have been proposed in the literature for the slip length associated with a moving contact line in diffuse interface models, by demonstrating each to apply in a different regime of the ratio of the microscopic interfacial width l and the macroscopic diffusive length lD=(Mη)1/2, where η is the fluid viscosity and M the mobility governing intermolecular diffusion. For small lD/l we find a diffuse interface regime in which the slip length scales as ξ∼(lDl)1/2. For larger lD/l>1 we find a sharp interface regime in which the slip length depends only on the diffusive length, ξ∼lD∼(Mη)1/2, and therefore only on the macroscopic variables η and M, independent of the microscopic interfacial width l. We also give evidence that modifying the microscopic interfacial terms in the model’s free energy functional appears to affect the value of the slip length only in the diffuse interface regime, consistent with the slip length depending only on macroscopic variables in the sharp interface regime. Finally, we demonstrate the dependence of the dynamic contact angle on the capillary number to be in excellent agreement with the theoretical prediction of Cox (J. Fluid Mech., vol. 168, 1986, p. 169), provided we allow the slip length to be rescaled by a dimensionless prefactor. This prefactor appears to converge to unity in the sharp interface limit, but is smaller in the diffuse interface limit. The excellent agreement of results obtained using three independent numerical methods, across several decades of the relevant dimensionless variables, demonstrates our findings to be free of numerical artefacts
Comprehensive evaluation of the linear stability of Alfv\'en eigenmodes
  driven by alpha particles in an ITER baseline scenario

The linear stability of Alfv\'en eigenmodes in the presence of fusion-born
alpha particles is thoroughly assessed for two variants of an ITER baseline
scenario, which differ significantly in their core and pedestal temperatures. A
systematic approach is used that considers all possible eigenmodes for a given
magnetic equilibrium and determines their growth rates due to alpha-particle
drive and Landau damping on fuel ions, helium ashes and electrons. This
extensive stability study is efficiently conducted through the use of a
specialized workflow that profits from the performance of the hybrid MHD
drift-kinetic code $\mbox{CASTOR-K}$ (Borba D. and Kerner W. 1999 J. Comput.
Phys. ${\bf 153}$ 101; Nabais F. ${\it et\,al}$ 2015 Plasma Sci. Technol. ${\bf
17}$ 89), which can rapidly evaluate the linear growth rate of an eigenmode. It
is found that the fastest growing instabilities in the aforementioned ITER
scenario are core-localized, low-shear toroidal Alfv\'en eigenmodes. The
largest growth-rates occur in the scenario variant with higher core
temperatures, which has the highest alpha-particle density and density
gradient, for eigenmodes with toroidal mode numbers $n\approx30$. Although
these eigenmodes suffer significant radiative damping, which is also evaluated,
their growth rates remain larger than those of the most unstable eigenmodes
found in the variant of the ITER baseline scenario with lower core
temperatures, which have $n\approx15$ and are not affected by radiative
damping
Exclusive $\omega$ meson muoproduction on transversely polarised protons

Exclusive production of $\omega$ mesons was studied at the COMPASS experiment
by scattering $160~\mathrm{GeV}/\mathit{c}$ muons off transversely polarised
protons. Five single-spin and three double-spin azimuthal asymmetries were
measured in the range of photon virtuality $1~(\mathrm{GeV}/\mathit{c})^2 < Q^2
< 10~(\mathrm{GeV}/\mathit{c})^2$, Bjorken scaling variable $0.003 <
x_{\mathit{Bj}} < 0.3$ and transverse momentum squared of the $\omega$ meson
$0.05~(\mathrm{GeV}/\mathit{c})^2 < p_{T}^{2} <
0.5~(\mathrm{GeV}/\mathit{c})^2$. The measured asymmetries are sensitive to the
nucleon helicity-flip Generalised Parton Distributions (GPD) $E$ that are
related to the orbital angular momentum of quarks, the chiral-odd GPDs $H_{T}$
that are related to the transversity Parton Distribution Functions, and the
sign of the $\pi\omega$ transition form factor. The results are compared to
recent calculations of a GPD-based model.Comment: 23 pages, 9 figure
Holographic Magnetisation Density Waves

We numerically construct asymptotically $AdS$ black brane solutions of $D=4$
Einstein theory coupled to a scalar and two $U(1)$ gauge fields. The solutions
are holographically dual to $d=3$ CFTs in a constant external magnetic field
along one of the $U(1)$'s. Below a critical temperature the system's
magnetisation density becomes inhomogeneous, leading to spontaneous formation
of current density waves. We find that the transition can be of second order
and that the solutions which minimise the free energy locally in the parameter
space of solutions have averaged stressed tensor of a perfect fluid.Comment: 24 pages, 7 figures; v2: references adde
Tissue Crowding Induces Caspase-Dependent Competition for Space.

Regulation of tissue size requires fine tuning at the single-cell level of proliferation rate, cell volume, and cell death. Whereas the adjustment of proliferation and growth has been widely studied [1, 2, 3, 4 and 5], the contribution of cell death and its adjustment to tissue-scale parameters have been so far much less explored. Recently, it was shown that epithelial cells could be eliminated by live-cell delamination in response to an increase of cell density [6]. Cell delamination was supposed to occur independently of caspase activation and was suggested to be based on a gradual and spontaneous disappearance of junctions in the delaminating cells [6]. Studying the elimination of cells in the midline region of the Drosophila pupal notum, we found that, contrary to what was suggested before, Caspase 3 activation precedes and is required for cell delamination. Yet, using particle image velocimetry, genetics, and laser-induced perturbations, we confirmed [ 6] that local tissue crowding is necessary and sufficient to drive cell elimination and that cell elimination is independent of known fitness-dependent competition pathways [ 7, 8 and 9]. Accordingly, activation of the oncogene Ras in clones was sufficient to compress the neighboring tissue and eliminate cells up to several cell diameters away from the clones. Mechanical stress has been previously proposed to contribute to cell competition [ 10 and 11]. These results provide the first experimental evidences that crowding-induced death could be an alternative mode of super-competition, namely mechanical super-competition, independent of known fitness markers [ 7, 8 and 9], that could promote tumor growth
Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7fb(-1) of root s=7 TeV proton-proton collisions

Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from >= 6 to >= 9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m(0), gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV
Strong and weak order in averaging for SPDEs

International audienceWe show an averaging result for a system of stochastic evolution equations of parabolic type with slow and fast time scales. We derive explicit bounds for the approximation error with respect to the small parameter defining the fast time scale. We prove that the slow component of the solution of the system converges towards the solution of the averaged equation with an order of convergence is $1/2$ in a strong sense - approximation of trajectories - and $1$ in a weak sense - approximation of laws. These orders turn out to be the same as for the SDE case
The stress hormone corticosterone in a marine top predatorreflects short-term changes in food availability

-In many seabird studies, single annual proxies of prey abundance have been
used to explain variability in breeding performance, but much more important
is probably the timing of prey availability relative to the breeding season when
energy demand is at a maximum. Until now, intraseasonal variation in prey
availability has been difficult to quantify in seabirds. Using a state-of-the-art
ocean drift model of larval cod Gadus morhua, an important constituent of the
diet of common guillemots Uria aalge in the southwestern Barents Sea, we were
able to show clear, short-term correlations between food availability and measurements
of the stress hormone corticosterone (CORT) in parental guillemots
over a 3-year period (2009–2011). The model allowed the extraction of abundance
and size of cod larvae with very high spatial (4 km) and temporal resolutions
(1 day) and showed that cod larvae from adjacent northern spawning
grounds in Norway were always available near the guillemot breeding colony
while those from more distant southerly spawning grounds were less frequent,
but larger. The latter arrived in waves whose magnitude and timing, and thus
overlap with the guillemot breeding season, varied between years. CORT levels
in adult guillemots were lower in birds caught after a week with high frequencies
of southern cod larvae. This pattern was restricted to the two years (2009
and 2010) in which southern larvae arrived before the end of the guillemot
breeding season. Any such pattern was masked in 2011 by already exceptionally
high numbers of cod larvae in the region throughout chick-rearing period. The
findings suggest that CORT levels in breeding birds increase when the arrival of
southern sizable larvae does not match the period of peak energy requirements
during breeding.

Cross-regulation of hepatic glucose metabolism ChREBP and Nuclear Receptors

International audienceThere is a worldwide epidemic of obesity and type 2 diabetes, two major public health concerns associated with alterations in both insulin and glucose signaling pathways. Glucose is not only an energy source but also controls the expression of key genes involved in energetic metabolism, through the glucose-signaling transcription factor, Carbohydrate Responsive Element Binding Protein (ChREBP). ChREBP has emerged as a central regulator of fatty acid synthesis (lipogenesis) in response to glucose under both physiological and physiopathological conditions. Glucose activates ChREBP by regulating its entry from the cytosol to the nucleus, thereby promoting its binding to carbohydrate responsive element (ChoRE) in the promoter regions of glycolytic (L-PK) and lipogenic genes (ACC and FAS). We have previously reported that the inhibition of ChREBP in liver of obese ob/ob mice improves the metabolic alterations linked to obesity, fatty liver and insulin-resistance. Therefore, regulating ChREBP activity could be an attractive target for lipid-lowering therapies in obesity and diabetes. However, before this is possible, a better understanding of the mechanism(s) regulating its activity is needed. In this review, we summarize recent findings on the role and regulation of ChREBP and particularly emphasize on the cross-regulations that may exist between key nuclear receptors (LXR, TR, HNF4α) and ChREBP for the control of hepatic glucose metabolism. These novel molecular cross-talks may open the way to new pharmacological opportunities
