Xenopus mRNAs that potentially encode gap junction proteins in the oocyte and early embryo have been identified by low-stringency screening of cDNA libraries with cloned mammalian gap junction cDNAs. The levels of these mRNAs show strikingly different temporal regulation and tissue distribution. Using a nomenclature designed to stress important structural similarities of distinct gap junction g...

In the major pathway of homologous DNA recombination in prokaryotic cells, the Holliday junction intermediate is processed through its association with RuvA, RuvB, and RuvC proteins. Specific binding of the RuvA tetramer to the Holliday junction is required for the RuvB motor protein to be loaded onto the junction DNA, and the RuvAB complex drives the ATP-dependent branch migration. We solved t...

The simplest junction between two superconductors hosts one Andreev bound state, which can be occupied by 0, 1, or 2 quasiparticles. properties of these many-body states are sensitive to the spatial structure single-particle wave functions as well charging effects. These influences revealed through microwave response junction.

in this study we investigate the effect of atoms such as b, n, ge and sn on the optical and the electrical properties of capped (5, 0) zigzag carbon nanotube, using dft calculation method. these elements were attached to the one end of the carbon nanotube. we considered four different structure designs as possible candidates for a p-n junction device. the electrical properties of these structur...

background: prolonged inhibition of acetylcholine esterase may lead to the intermediate syndrome. neuromuscular junction (nmj) dysfunction has been shown with repetitive nerve stimulation (rns). subclinical nmj dysfunction may also occur. we aimed to examine the nmj function following acute organophosphorus (op) poisoning by using exercise modified slow rns. methods: a cohort study was conducte...
