NDN

NDN can mean:

DOS Navigator

DOS Navigator is a free orthodox file manager for DOS, OS/2 and Windows.

Influence of DOS Navigator

DOS Navigator (DN) is an influential early implementation of orthodox file manager (OFM). By implementing three additional types of virtual file system (VFS): Xtree, Briefcase and list-based, DN opened a new generation of OFMs. Also an unlimited number of panels and many new important features make it one of the most powerful (and complex) OFMs.

History

The initial version of DN I (v 0.90) was released in 1991, and written by Stefan Tanurkov, Andrew Zabolotny and Sergey Melnik (all from Chişinău, Moldova). After that, DN was rewritten using Turbo Vision by Stefan Tanurkov and Dmitry Dotsenko (Dmitry developed DN at Moscow State University). These versions are sometimes referred as DN II.

In 1993, Slava Filimonov invited Stefan to join him to continue producing and publishing DN with joint efforts. Slava also contributed programming new components, design and made countless optimizations and improvements. He wrote a new software key protection system which remained unbreakable for almost four years after its introduction.

NDN (gene)

Necdin is a protein that in humans is encoded by the NDN gene.

Function

This intronless gene is located in the Prader-Willi syndrome (PWS) deletion region. It is an imprinted gene and is expressed exclusively from the paternal allele. Studies in mice suggest that the protein encoded by this gene may suppress growth in postmitotic neurons.

Necdin is used to stimulate growth regulation,and DNA-dependent transcription regulation.

Interactions
