Cell cycle checkpoints are evolutionarily conserved signaling pathways that uphold genomic integrity. Complete inactivation of the mouse checkpoint gene Hus1 results in chromosomal instability, genotoxin hypersensitivity, and embryonic lethality. To determine the functional consequences of partial Hus1 impairment, we generated an allelic series in which Hus1 expression was incrementally reduced...

OBJECTIVE After the arterial switch operation (ASO), disproportional neo-aortic growth during childhood has been reported. Even though it has been suggested neo-aortic dilation will stabilise in adulthood, data are lacking. The aim of this study was to assess the change in neo-aortic dimensions, prevalence of neo-aortic dilation >40 mm and long-term outcome in adults who underwent ASO in childh...

When cognitive scientists apply computational theory to the problem of phenomenal consciousness, as many have been doing recently, there are two fundamentally distinct approaches available. Consciousness is to be explained either in terms of the nature of the representational vehicles the brain deploys or in terms of the computational processes defined over these vehicles. We call versions of t...

BACKGROUND Modeling neo-aortic valve for arterial switch surgical planning to simulate the neo-aortic valve closure performance. METHODS We created five geometrical models of neo-aortic valve, namely model A, model B, model C, model D and model E with different size of sinotubular junction or sinus. The nodes at the ends of aorta and left ventricle duct fixed all the degrees of freedom. Trans...

Recently, we characterized neoamphimedine (neo) as an ATP-competitive inhibitor of the ATPase domain of human Topoisomerase IIα. Thus far, neo is the only pyridoacridine with this mechanism of action. One limiting factor in the development of neo as a therapeutic agent has been access to sufficient amounts of material for biological testing. Although there are two reported syntheses of neo, bot...
