Hochschild cohomology of abelian categories and ringed spaces

Author(s) : Lowen, M , VAN DEN BERGH, Michel
Description : This paper continues the development of the deformation theory of abelian categories introduced in a previous paper by the authors. We show first that the deformation theory of abelian categories is controlled by an obstruction theory in terms of a suitable notion of Hochschild cohomology for abelia...

Quasitriangular (G-cograded) multiplier Hopf algebras

Author(s) : DELVAUX, Lydia , Van Daele, A , Wang, SH
Description : We put the known results on the antipode of a usual quasitriangular Hopf algebra into the framework of multiplier Hopf algebras. We illustrate with examples which cannot be obtained by using classical Hopf algebras. The focus of the present paper lies on the class of the so-called G-cograded multipl...

Ideal classes of three dimensional Artin-Schelter regular algebras

Author(s) : DE NAEGHEL, Koen , VAN DEN BERGH, Michel
Description : We determine the possible Hilbert functions of graded rank one torsion free modules over three dimensional Artin-Schelter regular algebras. It turns out that, as in the commutative case, they are related to Castelnuovo functions. From this we obtain an intrinsic proof that the space of torsion free ...

Time analysis and entry-exit relation near planar turning points

Author(s) : DE MAESSCHALCK, Peter , DUMORTIER, Freddy
Description : The paper deals with canard solutions at very general turning points of smooth singular perturbation problems in two dimensions. We follow a geometric approach based on the use of C-k-normal forms, centre manifolds and (family) blow up, as we did in (Trans. Amer. Math. Soc., to appear). In (Trans. A...

Invariant manifolds of dynamical systems close to a rotation: Transverse to the rotation axis

Author(s) : BONCKAERT, Patrick , Fontich, E
Description : We consider one parameter families of vector fields depending on a parameter E such that for epsilon = 0 the system becomes a rotation of R-2 x R-n around {0} x R-n and such that for epsilon > 0 the origin is a hyperbolic singular point of saddle type with, say, attraction in the rotation plane and ...

Store-operated Ca2+-channels are sensitive to changes in extracellular pH

Author(s) : KALMAN, Katalin , LASKAY, Gabor , VAN KERKHOVE, Emmy , STEELS, Paul , AMELOOT, Marcel
Description : The sensitivity of store-operated Ca2+-entry to changes in the extra- and intracellular pH (pH(o) and pH(i), respectively) was investigated in SH-SY5Y human neuroblastoma cells. The intracellular Ca2+-stores were depleted either with I mM carbachol (CCH) or with 2 mu M thapsigargin (TG). Extracellul...

Novel candidate markers for multiple sclerosis using phage cDNA display.

Author(s) : SOMERS, Klaartje , SOMERS, Veerle , GOVARTS, Cindy , STINISSEN, Piet
Description : Multiple sclerosis (MS) is a chronic, inflammatory disease of the central nervous system, characterized by the presence of focal lesions resulting from myelin breakdown. In the past few years, an important contribution of B cells and autoreactive antibodies has been demonstrated in the pathogenesis ...

Premature senescence of the immune system in rheumatoid arthritis and multiple sclerosis patients.

Author(s) : LINSEN, Loes , THEWISSEN, Marielle , GEUSENS, Piet , RAUS, Jef , STINISSEN, Piet
Description : The decline in immunocompetence with age is accompanied by a steadily increasing incidence of autoimmune diseases. A reduced thymic output, which is an important aspect of immunosenescence will induce compensatory auto-proliferation. This process can lead to a premature senescence of T cells and con...

Synovial fluid NKT cells display different properties compared to peripheral blood NKT cells in rheumatoid arthritis

Author(s) : LINSEN, Loes , SOMERS, Veerle , THEWISSEN, Marielle , GEUSENS, Piet , RAUS, Jef , STINISSEN, Piet
Description : Natural killer T cells (NKT) are a population of regulatory T cells that co-express an invariant T cell receptor as well as NK cell markers. Several studies have shown that NKT cells are decreased or dysfunctional in autoimmune conditions such as insulin-dependent diabetes mellitus, systemic scleros...
