abstract background ulcerative colitis (uc) is characterized by recurrent episodes of inflammation limited to the mucosal layer of the colon. calprotectin is a zinc and calcium binding protein derived from neutrophils and monocytes. it is easily detectable in tissue samples, body fluids, and stools, which makes it a potentially valuable marker of inflammation. the aim of the current study is to...

A finite compact (FC) difference scheme requiring only bi-diagonal matrix inversion is proposed by using the known high-resolution flux. Introducing TVD or ENO limiters in the numerical flux, several high-resolution FC-schemes of hyperbolic conservation law are developed, including the FC-TVD, third-order FC-ENO and fifth-order FC-ENO schemes. Boundary conditions formulated need only one unknow...

This paper will use the concept of clearly visible to obtain a Krasnosel'skii-type theorem for the dimension of the kernel of a starshaped set, and the following result will be proved: For each fc and n, 1 < k < n, let f(n,n) = n -\1 and /(n, fc) = 2n if 1 < fc < n — 1. Let S be a nonempty compact set in Rn. Then for a fc with 1 < fc < n, dim ker S > fc if and only if every f(n, fc) points of b...

Barnes and Sloane recently described a "general construction" for lattice packings of equal spheres in Euclidean space. In the present paper we simplify and further generalize their construction, and make it suitable for iteration. As a result we obtain lattice packings in U with density A satisfying log2 A ~ — m logf m, as m -> oo, where logf m is the smallest value of k for which the fc-th it...

INTRODUCTION Faecal calprotectin (FC) has been proposed to be a biomarker of gastrointestinal (GI) disease in systemic sclerosis (SSc). The purpose of this study was to extend cross-sectional observations and prospectively assess the variability of FC over time in SSc patients. We also aimed to examine FC in relation to immunosuppressive therapy. Finally we wanted to analyse FC in other rheumat...

Receptors for the Fc portion of immunoglobulin (Ig)G (Fc gamma R) mediate phagocytosis of IgG-opsonized particles by a process that can be divided into four major steps: receptor-ligand binding, pseudopod extension, internalization, and lysosomal fusion. We have expressed single classes of Fc gamma R in COS fibroblasts to examine the structural determinants necessary to complete the four steps ...

OBJECTIVE To assess the effect of subsequent pregnancy after peripartum cardiomyopathy (PPCM) on maternal and fetal outcome. METHODS Prospective study of 34 patients with the diagnosis of PPCM (mean age = 26 years). At the time of first diagnosis 5 were in NYHA functional class (FC) II for heart failure, one in FC III and 28 in FC IV. After clinical treatment, patients were advised to avoid n...

We propose a new solver for the sparse spikes deconvolution problem over the space of Radon measures. A common approach to off-the-grid deconvolution considers semidefinite (SDP) relaxations of the total variation (the total mass of the absolute value of the measure) minimization problem. The direct resolution of this SDP is however intractable for large scale settings, since the problem size g...
