Background: Crohn's disease (CD) is a polygenic multifactorial heterogeneous disease. Anti-Saccharomyces Cerevisiae antibodies (ASCA) correlate highly with CD and are present in 50-80% of patients. The reason for ASCA positivity or negativity in CD is unknown. The aim of our work was to analyse clinical, epidemiological and genetic characteristics in ASCA + or ASCA- CD patients. Methods : 113 patients with CD were tested for ASCA (IgA and IgG) by using a commercial kit (Medipan Diagnostica). Age, gender, systemic manifestations, familial form of disease, age at diagnosis, location and behaviour of the disease, smoking habit as well as genotyping for -308 TNF gene polymorphisms were determined. Results : 38.9% CD patients were negative for both IgA and IgG ASCA while 61.1% were ASCA positive (respectively IgA and IgG : 31.9%; IgA only : 9.7%; IgG only : 19.5%). The only significant difference between ASCA+ and ASCA- patients was for smoking habit : there were 29% smokers in ASCA+ versus 50% in ASCA- CD patients (P = 0.03). This low proportion of smokers was more prominent in ASCA IgA+ patients than in isolated ASCA IgG+ patients (25.6% versus 45.5%) and was minimal in patients with high titers of ASCA IgA (0/8). Logistic regression showed smoking habit still borderline for significance (P = 0.057). Conclusions : Our results suggest a negative association between smoking and ASCA positivity in CD. This association was more prominent for ASCA IgA+. It indicates that smoking habit should be taken into account when analysing ASCA status in CD patients and may suggest an influence of smoking on immunization against intestinal material. [less ▲]

The colossal negative magnetoresistance Delta rho observed in La0.6Y0.1Ca0.3MnO3 at B=1 T shows an unusual, nearly perfect symmetry (around the peak temperature T-0=160 K), suggestive of a Curie-Weiss-dominated transport mechanism in this material both above and below the field-dependent Curie temperature T(C)equivalent to T-0. Attributing this symmetry to strong magnetic fluctuations below T-C (which are triggered by the Y substitution and cause a "bootstrap" destruction of the ferromagnetic phase), the data are interpreted in terms of the nonthermal spin hopping and magnetization-dependent charge carrier localization scenario leading to Delta rho=-rho(s)(1-e(-gamma M2)), with the magnetization M(T,B)=CB/\ T-T-C(B)\(nu). The separate fits through all the data points above and below T-C yield C(+)similar or equal to 2C(-) and nu(+)similar or equal to nu(-)similar or equal to 1, in agreement with the predictions of the Landau mean-field theory.

In order to better understand the fundamental issue regarding the compatibility between the quark-shell picture and that of resonances in meson-nucleon scattering in large $N_c$ QCD we extend the work of Cohen and Lebed on mixed symmetric $\ell $ = 1 baryons to analyze excited states with $\ell $ = 3. We give an explicit proof on the degeneracy of mass eigenvalues of a simple Hamiltonian including operators up to order $\mathcal{O}(N^0_c)$ \emph{i. e.} neglecting $1/N_c$ corrections in the quark-shell picture in the large $N_c$ limit. We obtain three degenerate multiplets formed of $\ell = 3$ states, as in the case of $\ell $ = 1 baryons. The compatibility between this picture and that of resonances in meson-nucleon scattering is discussed in the light of the present results. [less ▲]

We discuss the compatibility between the quark-shell picture and the meson-nucleon scattering picture in large $N_c$ QCD for mixed symmetric $\ell$ = 1 states previously analyzed by using a simple Hamiltonian including operators up to order $\mathcal{O}(N^0_c)$ defined in the standard ground state symmetric core + excited quark procedure. Here we introduce a Hamiltonian of order $\mathcal{O}(N^0_c)$ defined in a new approach where the separation of the system into two parts is not required. Three degenerate sets of states (towers) with the same quantum numbers as in the scattering picture and in the standard procedure are obtained. Thus the compatibility is equally achieved. The eigenvalues of the presently chosen Hamiltonian also have simple analytic expressions, depending linearly on the three dynamical coefficients entering the Hamiltonian. This reinforces the validity of the new approach which had already successfully described excited negative parity baryons in a large energy range. [less ▲]

We show that the two complementary pictures of large $N_c$ baryons - the single-quark orbital excitation about a symmetric core and the meson-nucleon resonance -- are compatible for $\ell$ = 3 SU(4) baryons. The proof is based on a simple Hamiltonian including operators up to order $\mathcal{O}(N^0_c)$ used previously in the literature for $\ell$ = 1. [less ▲]

The prion protein (PrP) when misfolded into the pathogenic conformer PrPSc is the major causative agent of several lethal transmissible spongiform encephalopathies in mammals. Studies of evolutionary pressure on the corresponding gene using different datasets have yielded conflicting results. In addition, putative PrP or PrP interacting partners with strong similarity to PrP such as the doppel protein have not been examined to determine if the same evolutionary mechanisms apply to prion paralogs or if there are coselected sites that might indicate how and where the proteins interact. We examined several taxonomic groups that contain model organisms of prion diseases focusing on primates, bovids, and an expanded dataset of rodents for selection pressure on the prion gene (PRNP) and doppel gene (PRND) individually and for coevolving sites within. Overall, the results clearly indicate that both proteins are under strong selective constraints with relaxed selection on amino acid residues connecting α-helices 1 and 2. © 2014 Springer Science+Business Media New York.

The main concepts dealing with negative refraction are clarified in order to understand if a high conductive metal layer thinner than the wavelength can really be considered as a metamaterial with a negative refraction index. The theoretical method to find the direction of phase velocity is clearly explained. The use of the causality principle is presented. We discuss why the negative refractive metamaterial has to be regarded as a dispersive one. Discussions are illustrated by means of FDTD simulations. The superlens application is presented. We explain why it is not obvious to consider a thin metal layer as a negative refractive material. [less ▲]
