Natural transformation is the widespread biological process by which "competent" bacteria take up free DNA, incorporate it into their genomes, and become genetically altered or "transformed".To curb often deleterious transformation by foreign DNA, several competent sara stedy stand aid species preferentially take up their own DNA that contains spec

In this article we show that a single transparent wedge or a read more plate with a wedge part can be used as a very simple and useful interferometer with numerous applications.This interferometer permits to modulate phase distribution on interference fringes to evaluate quantitatively the parallelism of a light beam and aberration of a wavefront,

Doublecortin-like kinase 1 (DCLK1) is a serine/threonine-kinase with two doublecortin (DCX) domains.DCLK1 is associated with microtubules via DCX domains and regulates microtubule polymerization.DCLK1 is known to be expressed in cancer stem cells and provides cancer cells with tumor-initiating capacity.Accumulating clinical evidence supports that D
