The Zfy gene is located on the Y chromosome of placental mammals and encodes a zinc finger protein which may serve as the primary sex-determining signal. A related gene, Zfx, is similarly conserved on the X chromosome. Unlike that in most mammals, the mouse genome contains four homologous zinc finger loci: Zfy-1, Zfy-2, Zfx, and Zfa (on an autosome). We report that, in contrast to the mouse Zfy...

Ternary semiconductor CdZnS films were prepared by chemical bath deposition (CBD). Effect of Zn concentration and deposition time on the forming chaarcterization of CdZnS films are investigated by the optical transmission spectra. The competition mechanism of Zn and Cd with the complexing agent NH3 to forming the complex play a critical role in the forming of Cd1-xZnxS thin film when Zn concent...

Zinc ion homeostasis in Saccharomyces cerevisiae is controlled primarily through the transcriptional regulation of zinc uptake systems in response to intracellular zinc levels. A high-affinity uptake system is encoded by the ZRT1 gene, and its expression is induced more than 30-fold in zinc-limited cells. A low-affinity transporter is encoded by the ZRT2 gene, and this system is also regulated ...

The corrosion inhibition of mild steel in 1 M HCl solution by some dihydropyridine has been studied using gravimetric, electrochemical impedance spectroscopy, potentiodynamic polarization techniques and quantum chemical study. results weight loss Tafel measurements showed that among the compounds, Isradipine good inhibiting properties for acidic bath, with 98% efficiency at optimum concentratio...

In the present work copper iron sulfide nanocrystalline thin film grown by chemical bath deposition (CBD) at acidic value of pH onto glass substrates has been systematically studied for effect annealing temperature. The deposited was characterized SEM its morphology, morphology showed a flower like structure, highly beneficial maximum absorption light. Raman Spectroscopy and XRD confirmed forma...

Acutolysin A alias AaHI, a 22 kDa hemorrhagic toxin isolated from the snake venom of Agkistrodon acutus, is a member of the adamalysin subfamily of the metzincin family and is a snake venom zinc metalloproteinase possessing only one catalytic domain. Acutolysin A was found to have a high-activity and a low-activity under weakly alkaline and acidic conditions, respectively. With the adamalysin I...

ZnO thin films with grain morphology were obtained over glass substrates using the sol–gel method; these films were used as substrates to grow ZnO nanorods using chemical bath deposition (CBD) technique. The transmittance percentage of two films was over 85% and the electrical resistivity decreased when ZnO nanorods were grown over the ZnO thin film with grain morphology. A laser is incident at...
