Wikify date May 2009 Orphan date February 2009 Cleanup rewrite date May 2009 Regenerative CellDivision Syndrome is a rare disease that was first discovered in the mid 1930s by Swedish scientist Priscilla Swindley. It is caused by X chromosome s that do not cross over doing the DNA process, and ultimately copy hundreds of X chromosomes. This creates particular problems for skin cells. The mutated chromosomes attach to one another and create a thick almost wrinkly affect to the skin. People born with this disease tend to look older than their years. Over the course of the person with the diseases lives, the X chromosomes dissolve and create the appearance of youthful rejuvenated skin. The disease baffles scientists with complexity, and research is still being carried out today. RCDS has been featured on Ripley s Ripley s Believe It or Not Believe it Or Not , as well as the new motion picture The Curious Case of Benjamin Button . The motion pictured is loosely based on the life of Andrew Dahreddine, a man known for his dashing features, as well as diva esque behavior. He is the best known person living with the disease and an advocate for science research. Today he is genetically a 50 year women, trapped in a 16 year old boys body. Only 5 cases have been documented in the United States, and no more than 10 throughout the world.

Left side Phragmoplast forms and cell plate starts to assemble in the center of the cell. Toawards the right Phragmoplast enlarges in a donut shape towards the outside of the cell, leaving behind mature cell plate in the center. The cell plate will transform into the new cell wall once cytokinesis is complete. Cytokinesis in terrestrial plant s occurs by cell plate formation. This process entails the delivery of Golgi apparatus Golgi derived and endosomal vesicles carrying cell wall and cell membrane components to the plane of celldivision and the subsequent fusion of these vesicles within this plane. After formation of an early tubulo vesicular network at the center of the cell, the initially labile cell plate consolidates into a tubular network and eventually a fenestrated sheet. The cell plate grows outward from the center of the cell to the parental plasma membrane with which it will fuse, thus completing celldivision . Formation and growth of the cell plate is dependent upon the phragmoplast , which is required for proper targeting of Golgi apparatus Golgi derived vesicles to the cell plate. As the cell plate matures in the central part of the cell, the phragmoplast disassembles in this region and new elements are added on its outside. This process leads to a steady expansion of the phragmoplast, and concomitantly, to a continuous retargeting of Golgi apparatus Golgi derived vesicles to the growing edge of the cell plate. Once the cell ... more details

It is an Reliability computer networking unreliable , connection oriented packet switching packet switched data communications protocol . Cell relay transmission rate s usually are between 56 kbit s and several gigabits per second . Asynchronous Transfer Mode ATM , a particularly popular form of cell relay, is most commonly used for home Digital Subscriber Line DSL connections, which often runs between 128 kbit s and 1.544 Mbit s Digital Signal 1 DS1 , and for high speed backbone connections OC 3 and faster . Cell relay protocols have neither flow control nor error correction capability, are information content independent, and correspond only to layers one and two of the Open Systems Interconnection Reference Model OSI Reference Model . Cell relay can be used for delay and jitter sensitive traffic such as voice and video. Cell relay systems break variable length user packets into groups of fixed length cells, that add addressing and verification information. frame telecommunications Frame length is fixed in hardware , based on time delay and user packet length considerations. One user data message may be segmented over many cells. Cell relay statems may also carry bitstream based data such as Plesiochronous Digital Hierarchy PDH traffic, by breaking it into streams of cells, with a lightweight synchronization and clock recovery shim.
