In this work, we aimed to build a 3D-model of NIK and to study the binding of pyrazolo[4,3-c]isoquinolines with a view to highlight the structural elements responsible for their inhibitory potency. However, in the course of this work, we unexpectedly found that the pyrazolo[4,3-c]isoquinolines initially reported as NIK inhibitors were neither inhibitors of this enzyme nor of the alternative NF-kappaB pathway, but were in fact inhibitors of another kinase, the TGF-beta activated kinase 1 (TAK1) which is involved in the classical NF-kappaB pathway.

Study on environmental factors influencing the urea content of cow milk in Wallonia (Belgium). The urea content in tank milk is currently assessed in Wallonia (Belgium) for all milk producers by the Comité du lait. A statistical analysis was carried out on 5,675,758 data collected over the 2002-2008 period in order to study the variation in the urea content in milk from cows according to the months of the years and the agronomy areas. The data were analyzed with a linear model (proc GLM) including the fixed effects of the area, the month of sampling, the year and the interactions. The fat and proteins contents in milk were used as covariables. The average urea content in milk over the six years was 258 mg.l-1. A proportion of 19% of the contents were over 350 mg.l-1and 10% over 400 mg.l-1. The model explained 35% of the variation of the urea content. Within the model, the agronomy area was the most explicative component (44%). It was followed by the area-month interaction (18.6%), the protein content (17.8%) and the month (10.5%). The variation of the urea content in milk could be mainly explained by the differences in the diets offered to the lactating dairy cows according to the agronomy areas. The composition of the diets varies with the crops produced and therefore with the agronomy area. Higher urea contents were observed in areas with a lot of pastures (grazing areas) than in the arable areas. In the grazing areas, feedstuffs higher in protein than in energy are consumed by the cows: the excess of protein is probably the reason for the higher urea content. The feedstuffs produced in the arable areas are more various with more diversified and balanced diets. The season influenced also the urea content, a higher urea content being observed during the summer period as compared with the winter period. The changes could be explained by dietary differences between the indoor winter period and the grazing period in Summer. During the indoor period, the dairy cows are offered normally a complete diet which is more balanced than during the grazing period. [less ▲]

Primary cutaneous lymphomas are distinguished by singular clinical, histological and prognostic features that are not shared by other lymphomas originating from the lymphoid tissues. This review is an update of the current concepts about the biology, diagnosis and treatment of mycosis fungoides, the most frequent entity among the primary cutaneous T cell lymphomas. It is currently established that mycosis fungoides originates from T lymphocytes normally homing the dermis. Such a situation implies that treatments at least in the initial stages of the disease, should primarily target the skin without searching for an impact on internal lymphoid tissues. [less ▲]

Objectives: To examine the performance of screening for preeclampsia (PE) by a combination of maternal factors, soluble endoglin (sEng), pregnancy associated plasma protein A (PAPP-A), placental growth factor (PlGF) and uterine artery lowest pulsatibility index (L-PI) at 11-13 weeks of gestation. Methods: Uterine artery L-PI, sEng, PAPP-A and PlGF were measured at 11-13 weeks in 90 singleton pregnancies that subsequently developed PE, including 30 that required delivery before 34 weeks (early-PE) and 60 with late-PE, and 180 unaffected controls. Screening performance for PE by maternal factors, sEng, PAPP-A, PlGF and uterine artery L-PI and their combinations was determined. Results: In early-PE, compared to controls, plasma sEng and uterine L-PI were significantly increased and serum PAPP-A and PlGF were decreased. In late-PE, compared to controls, serum PlGF was decreased and uterine L-PI was increased but plasma sEng and serum PAPP-A were not significantly different. In screening for early-PE, the detection rate at a 10% false positive rate was 46.7% for sEng alone and 96.3% for a combination of maternal factors, sEng, PlGF and uterine artery L-PI. Conclusions: Effective screening for early-PE can be provided by a combination of maternal factors, sEng, PlGF and uterine artery L-PI at 11-13 weeks. [less ▲]

OBJECTIVE: The risk of rheumatoid arthritis (RA) is increased in the offspring of individuals affected with various autoimmune disorders, including psoriasis. Recently, the deletion of 2 genes from the late cornified envelope (LCE) gene cluster, LCE3C and LCE3B, has been associated with psoriasis in several populations. The purpose of this study was to assess whether this polymorphic gene deletion could also be involved in susceptibility to RA. METHODS: We tested for association between the LCE3C_LCE3B copy number variant and a single-nucleotide polymorphism in strong linkage disequilibrium with this variant (rs4112788) and RA in 2 independent case-control data sets (197 and 400 samples from patients with RA, respectively, and 411 and 567 samples from control subjects, respectively), collected at 4 Spanish hospitals. All samples were directly typed for presence of the LCE3C_LCE3B deletion (LCE3C_LCE3B-del) by polymerase chain reaction, and association analysis was performed using the SNPassoc R package. RESULTS: An association of homozygosity for the LCE3C_LCE3B-del and rs4112788 C allele with the risk of RA was observed in the first data set and was replicated in an independent case-control set. A combined analysis showed an overall P value of 0.0012 (odds ratio [OR] 1.45, 95% confidence interval [95% CI] 1.16-1.81) for association of the LCE3C_LCE3B-del. When the analysis was stratified for serologic data, we observed association in anti-cyclic citrullinated peptide (anti-CCP)-positive patients (P = 0.012, OR 1.51 [95% CI 1.09-2.13]) but not in anti-CCP-negative patients. CONCLUSION: We have identified an association between the LCE3C_LCE3B-del and RA, and we have verified a pleiotropic effect of a common genetic risk factor (LCE3C_LCE3B-del) for autoimmune diseases that is involved in both psoriasis and RA.

This article addresses a particular aspect of EU external governance: rule selection. Drawing on institutionalist and power-based explanations we put forward an account for the choice of the specific rules that guide policy convergence between the EU and third countries. The proposed analytical framework broadens the scope of the studies examining the externalization of EU rules beyond its borders, in that we claim that the EU can promote policy convergence using rules other than the EU's. More specifically, the EU also promotes policy convergence on the basis of international and bilaterally developed rules. These analytical claims for explaining rule selection are checked against empirical data. We compare policy convergence between the EU and four neighbouring countries (Morocco, Ukraine, Georgia, and Russia) in three subfields within foreign and security policy: foreign policy dialogue, control of export of dual-use goods in the context of non-proliferation of weapons of mass destruction, and crisis management.

Purpose – The purpose of this paper is to introduce a perturbation method for the A-X geometric formulation to solve eddy-current problems and apply it to the feasibility design of a non-destructive evaluation device suitable to detect long-longitudinal volumetric flaws in hot steel bars. Design/methodology/approach – The effect of the flaw is accurately and efficiently computed by solving an eddy-current problem over an hexahedral grid which gives directly the perturbation due to the flaw with respect to the unperturbed configuration. Findings – The perturbation method, reducing the cancelation error, produces accurate results also for small variations between the solutions obtained in the perturbed and unperturbed configurations. This is especially required when the tool is used as a forward solver for an inverse problem. The method yields also to a considerable speedup: the mesh used in the perturbed problem can in fact be reduced at a small fraction of the initial mesh, considering only a limited region surrounding the flaw in which the mesh can be refined. Moreover, the full three-dimensional unperturbed problem does not need to be solved, since the source term for computing the perturbation is evaluated by solving a two-dimensional flawless configuration having revolution symmetry. Originality/value – A perturbation method for the A-X geometric formulation to solve eddy-current problems has been introduced. The advantages of the perturbation method for non-destructive testing applications have been described. [less ▲]

Analysis of the high-affinity IgE receptor genes reveals epistatic effects of FCER1A variants on total IgE levels and eczema risk. Allergy 2009; DOI: 10.1111/j.1398-9995.2009.02297.x. Abstract Background: High levels of total and allergen-specific IgE levels are a key feature in allergic diseases. The high-affinity receptor for IgE, which is composed of one alpha (FCER1A), one beta (FCER1B), and two gamma (FCER1G) subunits, represents the central receptor of IgE-induced reactions. In a genome-wide association scan, we recently identified associations between functional FCER1A variants and total serum IgE levels. Previous studies had reported linkage and association of FCER1B variants with IgE and atopic traits. The FCER1G gene has not yet been investigated with regard to atopy. Filaggrin (FLG) is the strongest known risk gene for eczema, in particular the allergic subtype of eczema. Methods: We investigated the association of FCER1A, FCER1B, and FCER1G variants with IgE in a large population-based cohort (n = 4261) and tested for epistatic effects using the model-based multifactor dimensionality reduction (MB-MDR) method. In addition, we investigated a potential interaction between FLG and FCER1A variants in a large collection of eczema cases (n = 1018) and population controls. Results: Three strongly correlated FCER1A polymorphisms were significantly associated with total and specific IgE levels as well as allergic sensitization. No associations were seen for FCER1B and FCER1G. After adjustment for FLG effects, a significant epistatic effect of the FCER1A variants rs10489854 and rs2511211 on eczema risk was detected. Conclusions: These results suggest that FCER1A variants by themselves and in combination influence IgE levels and act synergistically to influence eczema risk. [less ▲]

The present study reviews the literature on inflammation and remodelling mechanisms in chronic obstructive pulmonary disease (COPD). The development of COPD is associated with chronic pulmonary inflammation. Immunity (innate or adaptive) plays a role in its onset and continuation. Airways inflammation alters bronchial structure/function relations: increased bronchial wall thickness, increased bronchial smooth muscle tone, seromucosal gland hypersecretion and loss of elastic structures. Circulating markers of pulmonary inflammation indicate its systemic dissemination. Oxidative stress plays a major role in the onset and persistence of tissue abnormalities. The determinants of extra- and intra-cellular redox control are only partially known. Susceptibility genes, antioxidant system insufficiency and reduced levels of anti-age molecules and of histone deacetylation are also involved. The molecular and cellular targets of inflammation and remodelling are numerous and complex. Currently, tools exist to limit inflammation in COPD but not to act on structural remodelling. [less ▲]
