State-of-the-art branch-and-bound algorithms for the maximum clique problem (Maxclique) frequently use an upper bound based on a partition P of a graph into independent sets for a maximum clique of the graph, which cannot be very tight for imperfect graphs. In this paper we propose a new encoding from Maxclique into MaxSAT and use MaxSAT technology to(More)
—State-of-the-art branch-and-bound algorithms for the maximum clique problem (Maxclique) generally exploit the structural information of a graph í µí°º to partition í µí°º into independent sets, in order to derive an upper bound for the cardinality of a maximum clique of í µí°º, which cannot be very tight for imperfect graphs. On the other hand, while(More)
Ischemic stroke is a leading cause of mortality and permanent disability, with enormous financial repercussions on health systems worldwide. Ischemic brain injury results from a complex sequence of pathophysiological events that evolve over time. In order to examine the molecular mechanisms underlying middle cerebral artery occlusion (MCAO)-induced ischemic(More)
Endothelial progenitor cells (EPCs) play an important role in postnatal neovascularization. However, it is poorly understood whether EPCs contribute to lymphangiogenesis. Here, we assessed differentiation of a novel population of EPCs towards lymphatic endothelial cells and their lymphatic formation. CD34(+) VEGFR-3(+) EPCs were isolated from mononuclear(More)
Direct benzoylation of the two hydroxyl groups on chitosan was achieved using a phosphoryl mixed anhydride system, derived from trifluoroacetic anhydride (TFAA), benzoic acids (BAs), and phosphoric acid (PA). The reaction is operated as a one pot process under mild conditions that does not require neither an inert atmosphere nor dry solvents. The structures(More)
We have examined the ontogeny of BALB/c plaque-forming cell (PFC) responses to phosphorylcholine (PC) from fetal and neonatal liver by using the (CBA/N x BALB/c)F1 transplantation model. In this system, thymus-dependent (PC-keyhole limpet hemocyanin) and thymus-independent class 1 (PC-Brucella abortus, PC-lipopolysaccharide) PC antigens stimulate B cell(More)
Congenital brain arteriovenous fistulas (BAVFs) are rare neurovascular lesions of the brain, and few cases have been reported of their treatment with a combination of detachable coils and Onyx, especially in infants. Here, we present a case of 2 high-flow BAVFs occurring in a 12-month-old boy. Standard techniques of digital subtraction angiography were(More)
