History
Development of AutoCAD started in 1981 at the Palo Alto Research Center (PARC), founded by Apple Computer co-founder Steve Jobs and scientist Alan Kay. The first version was developed in the three-year period ending in March 1984, and was named “Liz.” Autodesk purchased the rights to Liz for $250,000 in February 1985, and announced the first public release in October of that year. Autodesk developed and marketed Autocad to designers, contractors, architects, engineers, drafters, civil engineers, students, hobbyists and others in the manufacturing industry.
On September 9, 1986, Autodesk released AutoCAD LT, a scaled-down version of AutoCAD that was licensed to specific users instead of being sold as a product. This allowed for those CAD users who were unable to afford the full AutoCAD package to still have access to powerful CAD capabilities.
A significant milestone in the history of AutoCAD was the release of AutoCAD R15 in 1996, which was the first of the first few significant releases of what became AutoCAD XP. In 1997, AutoCAD 98 was released and featured a cleaner look. Also in 1997, AutoCAD 2000 was released, which was the first to be available for both Windows and OS/2 platforms, as well as the first to run natively on Windows NT platforms. AutoCAD 2000 was also the first to feature AutoCAD’s then-new R2000 database engine and an upgraded drawing module.
AutoCAD 2002 was released in 2001 and was the first version of AutoCAD to include features of the AutoCAD R2000/3D engine. In 2003, the Microsoft Windows version of AutoCAD was renamed to AutoCAD R2004, in order to reflect the fact that the newest AutoCAD product had been released in the previous year. AutoCAD 2005 was released in 2004 and was the first release to fully utilize the AutoCAD R2000 engine. The first AutoCAD product to be installed on Apple’s OS X platform was AutoCAD 2006, which was released in 2005.
AutoCAD 2009 was released on November 19, 2008, and was based on AutoCAD 2008, which was a major release of the product. AutoCAD 2009 was the first AutoCAD release to use the R2010 database engine and natively run on the Windows Vista operating system.
AutoCAD 2010 was released in 2009

In addition, PDGF and its receptor are widely expressed in mesenchymal tissues, where they have been shown to play a critical role in developmental processes. The broad, long-term objectives of this research are to understand the function of the PDGF system in normal growth and differentiation. As a step toward this goal, the immediate aims of this application are: 1) to characterize the binding and biological properties of PDGF A-chain in platelets and other cell types; 2) to characterize the specificity of PDGF receptor molecules in various cell types; 3) to isolate and characterize mutant mouse PDGF receptors; and 4) to produce a large collection of null mutants of the PDGF beta-receptor gene. Antibodies and cDNA probes will be used to detect the cell surface PDGF A-chain, and a variety of cell types (platelets, fibroblasts, smooth muscle cells, osteoblasts, chondroblasts, skeletal muscle) will be assayed for expression of the PDGF receptor. Complementary RNA probes will be used to characterize the expression of the PDGF receptor and other related genes in developmentally relevant tissues and cell types. Mutant mouse PDGF beta-receptor genes will be produced by homologous recombination using embryonic stem cells. The mutant mouse models will then be

The main objective of the research is to determine the role of major lipoprotein, apolipoprotein (apo) E, in the mechanism of action of apo A-I, an HDL-associated, cholesterol lowering protein. Previous studies in our laboratory have shown that synthetic apo A-I is active in a reconstituted system. apo A-I functions as a lipid acceptor, both in vitro and in vivo, and apo E is required for lipidation of apo A-I to form apo A-I-A-E lipoproteins. The proposed research will identify the structural features of apo A-I and apo E that are essential for the interaction between the two proteins. In addition, we will develop a system for studying interaction of apo A-I and apo E with the glycosphingolipid, apo B-100, present on the surface of very low density lipoproteins and chylomicrons. We will also develop a system for assessing the interactions of apo E-lipoproteins with chylomicron remnant receptors in cultured cells. The interactions will be studied in detail using the cell-free reconstituted systems and in cells using immunoprecipitation and immunofluorescence microscopy techniques. The effects of atherogenic lipoproteins and lipids on the apo E-apo A-I interaction will be determined in order to determine the pathophysiological implications of the interaction. The interactions of apo E-apo A-I lipoproteins with membranes will be examined by determining the effects of the proteins on hydrolysis of phospholipids and phospholipase activation. In addition, the effect of the proteins on membrane-associated enzyme activities
