to perform stability analysis and study g*e interaction, eight commercial sugar beet varieties were evaluated in eight major sugar beet producing areas of karaj, mashad, miandoab, esfahan, shiraz, kermanshah, moghan and hamadan in three years using a randomized complete block design with four replications. the evaluated varieties were br1, 7233, pp.8, ic, 7233-p29, pp22, h5505 and 41rt. having ...

The title compound, KNa[H(6)PtMo(6)O(24)]·11H(2)O, contains a discrete hexa-molybdoplatinate(IV) [H(6)PtMo(6)O(24)](2-) poly-anion (1 symmetry), which has the highest level of protonation. Five O atoms of the central PtO(6) octa-hedron (μ(3)-atoms, Oc) and one O atom of an outer edge-sharing MoO(6) octa-hedron (O bridging μ(2)-atom, Ob) are protonated. The polyanions are connected by almost lin...

Human mutations in the cytoplasmic C-terminal domain of Slack sodium-activated potassium (KNa) channels result in childhood epilepsy with severe intellectual disability. Slack currents can be increased by pharmacological activators or by phosphorylation of a Slack C-terminal residue by protein kinase C. Using an optical biosensor assay, we find that Slack channel stimulation in neurons or trans...

Neuronal stressors such as hypoxia and firing of action potentials at very high frequencies cause intracellular Na+ to rise and ATP to be consumed faster than it can be regenerated. We report the cloning of a gene encoding a K+ channel, Slick, and demonstrate that functionally it is a hybrid between two classes of K+ channels, Na+-activated (KNa) and ATP-sensitive (KATP) K+ channels. The Slick ...

Abstract At present, no effective treatment exists for the clinical toxicity of cobalt nanoparticles (CoNPs, 30 nm) after metal-on-metal (MOM) artificial joint replacement. As such, a better understanding CoNPs-toxicity mechanism is necessary and urgent development safe detoxification drugs. Our purpose was to explore role bioactive nano-selenium (BNS, > 97%) in antagonizing CoNPs its throug...
