Electrochemical oxidation of some selected catechol derivatives, using cyclic voltammetry, in the presence of different 2-aryl-1,3-indandiones as nucleophiles, resulted in electrochemical synthesis of new 1,3- indandione derivatives in an undivided cell in good yield and purity. A Michael addition mechanism was proposed for the formation of the analogs based on the reaction conditions which wer...

The nucleus is not only the control hub of cell life activities, but also center storing and controlling genetic information. morphology can be used to judge vitality health. various biological molecules contained in are closely related normal occurrence development diseases. In recent years, fluorescence imaging has gained increasing attention due its advantages being intuitive, situ visual. f...

This research presents the unusual staining characteristic of teleosts red blood cells–the common bluestripe snapper Lutjanus kasmira, caught at Toc Tan (Allison) Reef, Truong Sa Archipelago, Vietnam, due to side effects delayed procedure. In addition quantitative data measured, results microscopic image showed that, on slides performed with Romanovsky procedure using Giemsa dye, cell "nucleus"...

When blood components (e.g., leukocytes and platelets) adhere to a surface (e.g., blood vessel wall), shear flow causes the elongation of the non-adherent part of the cell membrane forming a long thin cylinder shape (i.e., cell tether). The formation of cell tether is important for regulation of cell adhesion strength and stabilization of cell rolling, and may significantly affect the flow dyna...

The recent discovery of nuclear and perinuclear perlecan in annulus fibrosus nucleus pulposus cells its known matrix stabilizing properties tissues introduces the possibility that may also have intracellular or regulatory roles through interactions with envelope cytoskeletal proteins nucleosomal-chromatin organization regulate transcriptional factors modulate gene expression. is a mechano-senso...

The ultrasturcture of the cell nucleus and perinuclear cytoplasm in Acetabularia is quite different in young and old cells. When a nucleus of an old cell was implanted into the cytoplasm of a young cell the nucleus assumed the morphology typical of a young cell within less than 10 days. The cytoplasm of an old cell was able to induce the reverse change in an implanted nucleus from a young cell....

Acetabularia acetabulum is a single-celled green alga which has historically been an important model system in cell biology. Here, we attempt to re-introduce A. as through the investigation of subcellular localization mRNAs. macroscopic with highly complex cellular morphology. The gigantic, and single nucleus, located at basal end, several centimeters away from umbrella-shaped tip. To better un...
