NEM is a peer-to-peer cryptocurrency launched on March 31, 2015 and written in Java. NEM has a stated goal of a wide distribution model and has introduced new features in blockchain technology in its proof-of-importance (POI) algorithm. NEM also features an integrated P2P secure, multisignature accounts and encrypted messaging system and an Eigentrust++ reputation system. NEM technology is used in the private blockchain Mijin being tested by financial institutions and private companies in Japan.
NEM was started by a Bitcoin Talk forum user called UtopianFuture after having been inspired by Nxt and wanted to improve upon it. Starting on January 19th, 2014, an open call for participation began on bitcointalk.org. The goal was to create a community-oriented cryptocurrency from the ground up.
NEM has gone through extensive open alpha testing starting June 25, 2014, followed by lengthy and comprehensive beta testing starting on October 20, 2014.
The NEM developers are partially pseudonymous.
Actin, alpha skeletal muscle is a protein that in humans is encoded by the ACTA1 gene.
Actin alpha 1 which is expressed in skeletal muscle is one of six different actin isoforms which have been identified. Actins are highly conserved proteins that are involved in cell motility, structure and integrity. Alpha actins are a major constituent of the contractile apparatus.
Skeletal alpha actin expression is induced by stimuli and conditions known to cause muscle formation. Such conditions result in fusion of committed cells (satellite cells) into myotubes, to form muscle fibers. Skeletal actin itself, when expressed, causes expression of several other "myogenic genes", which are essential to muscle formation. One key transcription factor that activates skeletal actin gene expression is Serum Response Factor ("SRF"), a protein that binds to specific sites on the promoter DNA of the actin gene. SRF may bring a number of other proteins to the promoter of skeletal actin, such as andogen receptor, and thereby contribute to induction of skeletal actin gene expression by androgenic (often termed "anabolic") steroids.
