$100 Diagnosis and Repair Parts-People has been specializing in Dell laptops for 20 years. We are a leading supplier of Dell replacement parts and stock all laptop repair parts needed to repair your Dell laptop. We are a trusted supplier to 1000s of schools, government agencies, military and repair shops worldwide. Send your laptop to the Dell Experts!
Most of our orders are from repeat customers. Parts-People began as a small company 20 years ago in an extra bedroom of my house. I had saved a small sum of money to purchase some computer parts and began selling them on eBay. After a few months I realized that people needed a place to go for Dell parts so I began building our website. Since we are located in Austin, Texas, where Dell.com was founded, I was able to set up a solid supply line with Dell. From the start, we focused on customer satisfaction and selling quality parts. We have grown a lot since 2002 but still and always the customer will come first. You will find that we go above and beyond with every order and offer free resources and support before and after the sale.

Knee problems involving the meniscus, the protective lining around the knee joint, can cause a bunch of problems, including long-term pain and arthritis. Orthopedists also have a hard time repairing a torn meniscus, usually involving the removal of the tear, which, over time, leaves the knee without important shock absorbers it needs. The most vulnerable to this type of injury include athletes and the elderly. Now doctors at New York's Columbia University Medical Center have come up with an innovative treatment alternative by 3D printing a knee meniscus implant.
The process involves using a degradable plastic scaffold and protein growth system. First, MRI scans are taken of a patient's undamaged menisci, then converted into a 3D image. Using a material called polycaprolactone, a biodegradable polymer, an intact 3D printed meniscus is formed (3D Print). The scaffold works a lot like coral scaffolds used in extreme body modification. Like coral, the 3D printed model works with special growth factors to naturally adapt to the human body. In this case, the scaffold contains infused human proteins encapsulated in slow-dissolving polymeric microspheres (Medgadget), allowing the body to naturally replace the implant with real tissue.
The coolest part of this new technology has to be how the internal body accepts the implant, and encourages cellular interaction. In typical tissue engineering procedures, researchers take stem cells from the patient's body and work in the lab to promote cellular regeneration. The first test subjects have not been humans, but sheep, whose meniscus successfully “regenerated in four to six weeks”. Humans are of course next. Once the process is refined a bit, the procedure would only take a few days to be completed. The only thing the researchers are waiting for is funding to begin human clinical trials.
