What regulates chromosome segregation dynamics in bacteria is largely unknown. Here, we show in Caulobacter crescentus that the polarity factor TipN regulates the directional motion and overall translocation speed of the parS/ParB partition complex by interacting with ParA at the new pole. In the absence of TipN, ParA structures can regenerate behind the partition complex, leading to stalls and...

Two new octasaccharides were isolated from human milk of a nonsecretor Lewis a+bindividual. Structural studies by sequential enzymic degradation and by quantitative methylation analysis revealed that their structures were as follows: Gal/31 + 3 (Fuccul + 4) GlcNAcPl + 3Gal/H -+ 4 (Fucal -+ 3) GlcNAcPl + 3Gal/31+ 4Glc, Gal/?1 + 4 (Fuccul -+ 3) GlcNAcj31 + 3Gal/31 -+ 4 (Fuccul -+ 3) GlcNAcj31 + 3...

objective(s)para-nonylphenol (p-np) is used in many industries and our previous study showed that p-np causes a reduction in rats bone marrow mesenchymal stem cells (mscs) viability. the aim of this study was to investigate the effect of p-np on osteogenic differentiation of mscs.materials and methodsmscs were isolated and expanded to 3rd passage, then cultured in dmem supplemented with osteoge...

We consider a sequence of quantum states, $\rho_N$, associated with submanifold $\Lambda$ product two integral compact Kahler manifolds. show that, when is submanifold, then, in the semiclassical limit, these states are not entangled. discuss whether geometry (specifically being submanifold) has any relationship entanglement properties $\rho_N$.

We define and study the notion of hyper-Kahler category. On theoretical side, we focus on construction techniques deformation theory such categories. also in details some examples : non-commutative Hilbert schemes points a K3 surface categorical resolution relative compactified Prymian constructed by Markushevich Tikhomirov. *
