This bay is connected with the Caspian Sea through the Ashooradeh-Chopoqli channels. The purpose of this research is to determine the water level fluctuation of the Caspian Sea with the physical and chemical characteristics of the sediments. for this purpose, sedimentological and statistical parameters were done. So field surveys were conducted to control remote sensing observations. A sedimentary core with maximum depth of 37 cm was taken using a PVC tube. A total of 7 sediment samples from the target core and 2 surface sediment samples were collected and analyzed. Sediments were separated based on texture, type of sediments, organic matter, color, and presence of plant and shell residues. Sampling was done based on changes in the sediment type and sedimentary facies. Grain size distribution of the particles equal to or greater than sand was performed using a wet sieve shaker, while smaller particles (silt an...

The sirtuins rely on nicotinamide adenine dinucleotide (NAD<sup>+</sup>) for their reaction. In the deacetylation process, sirtuins remove the acetate group from the terminal amine of the lysine roots in the structure of a protein and add it to NAD<sup>+</sup> and releases NAM,2-OAADPr and the deacetylated protein. In the mono-ADP-ribosyl transferase process, the ADP ribosyl root from the NAD<sup>+</sup> added to the protein and releases NAM and ADP-ribosyl protein. Abbreviations: NAM: nicotinamide, 2-OAADPr: 2-O-acetyl-ADP-ribose. <br>
