Smooth pursuit eye movements are guided largely by retinal-image motion. To compensate for neural conduction delays, the brain employs a predictive mechanism to generate anticipatory pursuit that precedes target motion (E. Kowler, 1990). A critical question for interpreting neural signals recorded during pursuit concerns how this mechanism is interfaced with sensorimotor processing. It has been...

PROBLEM Gerontology observations show that ageing of organism is accompanied by the decrease of the chromatin activity and slowing down of the protein synthesis. Natural regulatory oligopeptides and their synthetic analogues take part in the activation of chromatin and normalise rate of the protein synthesis in cultured tissues. Regulatory peptides significantly enhance longevity. OBJECTIVES ...

The positions of approximately 4,800 individual miniature inverted-repeat transposable element (MITE)-like repeats from four families were mapped on the Caenorhabditis elegans chromosomes. These families represent 1-2% of the total sequence of the organism. The four MITE families (Cele1, Cele2, Cele14, and Cele42) displayed distinct chromosomal distribution profiles. For example, the Cele14 MIT...

Reaction of thionyl chloride with 2-acetyl-1- benzenesulfonylpyrrole semicarbazone (6 c) gave 4 - (1- benzenesulfonyl-2 - pyrrolyl) - 1, 2, 3 -thiadiazole (lc). Selenium dioxide oxidation of 2-acetylpyrazine semicarbazone (10) in acetic acid afforded 4- (2-pyrazinyl) - 1, 2, 3- selenadiazole (4). Reaction of thionyl chloride with compound 10 gave 4- (2-pyrazinyl) - 1, 2, 3- thiadiazole (3)....

In this work, we use similarly separable vectors in Hilbert spaces to provide generalized integral results related majorization, Niezgoda, and Ćebysév type inequalities. Next, furnish some refinements of these Theorems obtained work extend improve several known the literature. An important aspect our is that inequalities are directly Arithmetic, Geometric, Harmonic, Power means. These means hav...

During cell migration, cell-substrate binding is required for pseudopod anchoring to move the cell forward, yet the interactions with the substrate must be sufficiently weak to allow parts of the cell to de-adhere in a controlled manner during typical protrusion/retraction cycles. Mammalian cells actively control cell-substrate binding and respond to extracellular conditions with localized inte...
