Enterprise resource planning Advantages
In the absence of an ERP system, a large manufacturer may find itself with many software applications that do not talk to each other and do not effectively interface. Tasks that need to interface with one another may involve:
design engineering (how to best make the product)
order tracking from acceptance through fulfillment
the revenue cycle from invoice through cash receipt
managing interdependencies of complex Bill of Materials
tracking the 3-way match between Purchase orders (what was ordered), Inventory receipts (what arrived), and Costing (what the vendor invoiced)
the Accounting for all of these tasks, tracking the Revenue, Cost and Profit on a granular level.
Change how a product is made, in the engineering details, and that is how it will now be made. Effective dates can be used to control when the switch over will occur from an old version to the next one, both the date that some ingredients go into effect, and date that some are discontinued. Part of the change can include labeling to identify version numbers.
Some security features are included within an ERP system to protect against both outsider crime, such as industrial espionage, and insider crime, such as embezzlement. A data tampering scenario might involve a disgruntled employee intentionally modifying prices to below the breakeven point in order to attempt to take down the company, or other sabotage. ERP systems typically provide functionality for implementing internal controls to prevent actions of this kind. ERP vendors are also moving toward better integration with other kinds of information security tools.[4]

stem cells called satellite cells
Signaling to muscle satellite cells
Studies reveal new mechanisms essential to muscle growth and repair
Three papers this month indicate how muscle regeneration could be induced via cell therapy or delineate the mechanisms by which it happens naturally.
Researchers led by Rita Perlingeiro at the University of Texas Southwestern Medical School, differentiated mouse embryonic stem cells into muscle progenitor cells which restored function when infused into mice with a mouse version of Duchenne's muscular dystrophy, a wasting disease1. The researchers genetically engineered embryonic stem cells to produce a protein (the transcription factor Pax3) that promotes muscle development in embryos. Initially, transplanting these cells produced teratomas so the researchers selected a subset of this population based on cell markers and tried again. When transplanted into mouse muscle or infused into the bloodstream, these cells did not form tumours but instead engrafted widely in diseased muscle tissue and improved its function, at least by some measures. Though these results are too early to be tried to humans, they support the eventual use of cell-based therapies for certain muscle-wasting diseases.
Normally, adult skeletal muscle is regenerated by stem cells called satellite cells. When activated by muscle damage, the cells proliferate and differentiate into myoblasts. These then fuse with mature myofibres to generate new tissue. The molecular signals governing these events are still obscure, but in a recent issue of Cell Stem Cell, researchers at Stanford University describe a time-sensitive regulatory pathway that determines the fate of satellite cells and, ultimately, the success of muscle repair2.
Thomas Rando and his team showed that levels of secreted signalling proteins called Wnts gradually increase in the muscle fibres and satellite cells of adult mice after injury, and drive the conversion of proliferating satellite cells into differentiated myoblasts. Wnts are well-known signalling molecules that are active in muscle tissue during development and are involved in the build-up of connective tissue in the muscles of ageing mice3. The new experiments showed the Stanford researchers that timing is everything. Inhibition of Wnt signalling immediately after injury had no effect on muscle repair, whereas later inhibition led to fewer new muscle fibres and impaired regeneration. The authors interpreted this to mean that Wnts are involved with the switch between proliferation and differentiation.
The timing of this switch was so critical to the formation of healthy new muscle that the researchers wanted to determine how it is controlled. They had previously discovered that another signalling pathway, initiated by the receptor Notch, was essential for cell proliferation early in muscle regeneration in mice4, and set out to determine if there was a relationship between the functions of Notch and Wnt signalling. They did indeed show direct molecular cross-talk between the two signalling pathways in satellite cells via the intracellular signaling molecule GSK3, which is downstream of both. When Notch is active Wnt signalling is suppressed, and vice versa.
