Isolated follicular dendritic cells (FDCs) showed true and pseudoemperipolesis of fresh tonsillar lymphocytes, even after long-term (50-day) cultivation. Emperipolesis by FDCs was not restricted by allotype specificity, nor was it inhibited by the addition of antibodies against MHC-I & II antigens. Follicular dendritic cells predominantly engulfed B-cells; monocytes and macrophages were not found between FDC cytoplasmic extensions. When highly purified T-cell populations were added to FDC cultures emperipolesis of T-cells occurred, particularly those of the CD4-positive phenotype. Mitoses appeared within 6 h in the emperipolesed lymphocytes and, after an additional 18 h, some lymphocytes exhibited apoptosis. [less ▲]

Bovine leukemia virus (BLV) is a deltaretrovirus that infects and induces accumulation of B-lymphocytes in the peripheral blood and lymphoid tissues of cattle, leading to leukemia/lymphoma. BLV can also be experimentally transmitted to sheep, in which disease appears earlier and at higher frequencies. Abnormal accumulation of leukemic B-lymphocytes results from an alteration of different parameters that include cell proliferation and death as well as migration to lymphoid tissues. Interestingly, B lymphocyte turnover is increased in BLV-infected sheep but reduced in cattle, revealing a potential relationship between cell kinetics and disease progression. [less ▲]

This paper shows how "Empire" from Negri and Hardt is a good exemplification of the "immanentist" turn in the theory of power and domination : to take the words of the authors, power is not "something above our heads, but something we make". Recovering one of the claims of Foucaut but probably with a rather different intention, this book is a great advance toward a more plausible theory of domination but is far from helping to find solutions.

Ce cours de 2h constitue la leçon inaugurale au module « Pensée et civilisation » de l'Espace universitaire liégeois, consacré, en 2014, au XIXe siècle sous ses divers aspects. Les cours-conférences à venir s’appesantiront sur des réalités politiques, sociales et juridiques qui feront naviguer l'auditoire du Premier Empire à la Belgique indépendante. Il semblait donc indispensable de préparer ces futures leçons en développant l’origine du Grand Empire, jusqu’à son apogée en 1812, et en s’attachant surtout à le définir dans l’espace. Or, pointer l’origine de l’Empire et de son territoire oblige, nécessairement, à envisager l’état de l’Europe en 1789, au moment où se déclenche la Révolution française. Il s'agit donc d'un parcours dans l'histoire française et européenne de 1789 à 1812. [less ▲]

In this article, we investigate the convergence process within the European Union. More particularly, we study the convergence process of the new entrants from Central and Eastern Europe and of the 15 Western countries between 1990 and 2007. Applying a panel approach to the convergence equation derived from the Solow model, we show that new entrants and former members of the European Union can be seen as belonging to different groups of convergence. The existence of heterogeneity in the European Union or the Eurozone might affect their stability as the recent Greece’s sovereign debt crisis illustrates it. [less ▲]

In this paper, we investigate the convergence process within the European Union (27 countries). More particularly, we study the convergence process of the new entrants from Central and Eastern Europe and of the 15 Western countries between 1990 and 2007. Applying a panel approach to the convergence equation derived by Mankiw et al.

Distributed linear solutions of the EEG source localisation problem are used routinely. In contrast to discrete dipole equivalent models, distributed linear solutions do not assume a fixed number of active sources and rest on a discretised fully 3D representation of the electrical activity of the brain. The ensuing inverse problem is underdetermined and constraints or priors are required to ensure the uniqueness of the solution. In a Bayesian framework, the conditional expectation of the source distribution, given the data, is attained by carefully balancing the minimisation of the residuals induced by noise and the improbability of the estimates as determined by their priors. This balance is specified by hyperparameters that control the relative importance of fitting and conforming to various constraints. Here we formulate the conventional "Weighted Minimum Norm" (WMN) solution in terms of hierarchical linear models. An "Expectation-Maximisation" (EM) algorithm is used to obtain a "Restricted Maximum Likelihood" (ReML) estimate of the hyperparameters, before estimating the "Maximum a Posteriori" solution itself. This procedure can be considered a generalisation of previous work that encompasses multiple constraints. Our approach was compared with the "classic" WMN and Maximum Smoothness solutions, using a simplified 2D source model with synthetic noisy data. The ReML solution was assessed with four types of source location priors: no priors, accurate priors, inaccurate priors, and both accurate and inaccurate priors. The ReML approach proved useful as: (1) The regularisation (or influence of the a priori source covariance) increased as the noise level increased. (2) The localisation error (LE) was negligible when accurate location priors were used. (3) When accurate and inaccurate location priors were used simultaneously, the solution was not influenced by the inaccurate priors. The ReML solution was then applied to real somatosensory-evoked responses to illustrate the application in an empirical setting. (C) 2004 Elsevier Inc. All rights reserved. [less ▲]
