Resistance to Cry toxins can develop by alterations in any of the steps in the Cry toxin mode of action. Most characterized mechanisms of resistance to Cry toxins involve alterations in enzymatic toxin processing or toxin interaction with receptors in the insect midgut epithelium. Previous reports have suggested an alternative mechanism of resistance to Cry1Ac toxin in Heliothis virescens larva...

The cat cry syndrome (cri-du-chat) was first described by Lejeune et al (1963) in a group of patients with mew-like cry and other congenital anomalies who had a partial deletion of the short arm of a B group chromosome. This partially deleted B group chromosome was subsequently found to be No. 5 by autoradiographic studies performed by German et al (1964). Other prominent manifestations of this...

The Nano-CrY zeolite synthesized and characterized by Fourier transfer infrared (FT-IR), X-ray diffraction (XRD),and Scanning electron microscopy (SEM).The result show that nano catalyst prepared with mainly particles size about 30-80 nm .The XRD show the structure of the zeolite does not collapse. This Nano-CrY zeolite has been used as new, and nontoxic catalyst for catalyzes of synthesis of 2...
