Sirtuin 1, also known as NAD-dependent deacetylase sirtuin-1, is a protein that in humans is encoded by the SIRT1 gene. [5] [6] [7]SIRT1 stands for sirtuin (silent mating type information regulation 2 homolog) 1 (S. cerevisiae), referring to the fact that its sirtuin homolog (biological equivalent across species) in yeast (Saccharomyces cerevisiae) is Sir2.
In September 2003, Howitz and Sinclair et al. published a highly cited paper reporting that polyphenols such as resveratrol [2] activate human SIRT1 and extend the lifespan of budding yeast (Howitz et al., Nature, 2003).

[2] [3] They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. [2] Chemically, sirtuins are a class of proteins that possess either mono- ADP-ribosyltransferase or deacylase activity, including deacetylase, desuccinylase , demalonylase , demyristoylase and depalmitoylase activity.
NAD-dependent deacetylase sirtuin 2 is an enzyme that in humans is encoded by the SIRT2 gene. [ 5 ] [ 6 ] [ 7 ] SIRT2 is an NAD+ (nicotinamide adenine dinucleotide)-dependent deacetylase. Studies of this protein have often been divergent, highlighting the dependence of pleiotropic effects of SIRT2 on cellular context.
Ogle is a DVD player for Linux, and other Unix-like operating systems.It was released as free software under the GNU GPL license.It was originally developed in 1999 by a few students at Chalmers Tekniska Högskola (Chalmers University of Technology) in Göteborg, Sweden, and maintained until late 2003.
libdvdcss (or libdvdcss2 in some repositories) is a free and open-source software library for accessing and unscrambling DVDs encrypted with the Content Scramble System (CSS). libdvdcss is part of the VideoLAN project and is used by VLC media player and other DVD player software packages, such as Ogle, xine-based players, and MPlayer.
DVD Flick is an open source DVD authoring application for Windows developed by Dennis Meuwissen and released under the GNU General Public License. DVD Flick is capable of importing audio tracks, video files and subtitles, composing a DVD-Video movie and burning it to a disc – or creating an ISO image for later burning. [2]
