LONDON Rush Vontae Davis Jersey , Aug. 7 (Xinhua) -- Patients who have damaged their knees could in the future get help from a new artificial meniscus being developed by a team from Imperial College London, the college announced on Friday.


The knee meniscus is a structure that supports the mechanical integrity of the knee and helps to distribute impact. Meniscal tearing is a very common injury and often leads to severe pain, restricted movement, and osteoarthritis.


These tears occur most often in athletes and the elderly and rarely heal. There are treatments such as human tissue implants, but they are not widely available and it is still not clear if they are effective.


Now Rush Adolphus Washington Jersey , researchers at Orthonika, a new business created by Imperial scientists jointly with the company Sierra MedTech, are developing an artificial knee meniscus that mimics the complex fibrous structure of real ones, which is able to cope with the high stresses and loads associated with the knee.


The meniscus has an extremely complex structure and is subject to high stresses. It needs to be both elastic and strong, capable of adapting to an individual's movement. "Our team have studied the structure of a natural meniscus and how it reacts to different forces to design a substitute that would function like a natural meniscus. We have also designed a surgical insertion procedure and related instruments Rush Taron Johnson Jersey , such as a secure means of fixation to the bone," said Professors Andrew Amis, who led the project.


The next steps at Orthonika will be to further advance and test knee meniscus designs. The researchers will also explore ways to develop the prototypes into a product for sale on the mass market, develop methods for how the technology can be applied in clinical settings and move towards obtaining the relevant regulatory approvals in the UK.



Alright, if you’re trying to find the best rated digital cameras Rush Harrison Phillips Jersey , then that’s exactly just what you’re going to get here. We will take a look at the top 5 top rated digital cameras on the market. These are: Nikon D700, Canon EOS Rebel T2i, Nikon D7000, Nikon D3100, and also Canon Rebel XS.



Nikon D700



The Nikon D700 is halfway in between the semi professional D300 and the leading D3. It is Nikon’s 2nd full frame digital camera Rush John Miller Jersey , and uses the same image sensing unit as the D3. So, what is whole frame all about? A complete frame sensor is a great deal bigger than the regular frame sensor found in the majority of digital SLR cameras, and is the same as 35mm roll film.



Do you know the most important advantages of using a larger sized picture sensor? Okay, to start with it means there isn’t any kind of field reduction whenever you connect a lens, and that means you don’t have to calculate the focal length by multiplying it by 1.6 or anything. For instance Rush Shaq Lawson Jersey , on a whole frame digital slr, if you fit a 14mm wide angle lens onto it, you then actually do get a focal length of 14mm. Another advantage is that a big image sensing unit is a lot more sensitive to lighting, as a consequence of individual pixels being much bigger. Which means that you will definately get much less photo noise in low light shooting.



Additional features of the Nikon D700:
12.1-megapixel FX-format (23.9 x 36mm) CMOS sensing unit
3.0-inch, 920 Rush Nathan Peterman Jersey ,000-dot VGA color monitor
170-degree wide-angle viewing as well as tempered-glass protection
Speedy, accurate 51-point AF system
3 dimensional Focus Tracking and 2 Live View shooting modes
Basic ISO range from 200-6400 can be extended to vary from ISO one hundred (Lo-1) to 25,600 (Hi-2); 0.12-second start-up speed
Capture images to CF III cards



Canon EOS Rebel T2i



Canon’s EOS Rebel T2i, also know as 550D in Europe and Asia, is a fantastic digital camera for the money. For an entry-level dslr Rush Dion Dawkins Jersey , it offers quite a few high end features, a few of them very much like the 7D that’s about a thousand bucks higher priced. For example, the high definition movie recording is equally as good as the 7D. Also, the eighteen megapixel image sensing unit means you’ll get ultra hi-res pics. It should be said though, that the auto-focus isn’t quite as good as a professional dslr. Nonetheless Rush Zay Jones Jersey , it is only seriously a problem when you’re probably going to be shooting professional sports images. But for the majority of photography lovers it won’t become a problem.



Features:
18.0-megapixel CMOS (APS-C) sensing unit; DIGIC 4 picture processor chip for high picture quality and speed
Kit contains 18-55mm f3.5-5.6 IS lens
ISO 100-6400 (expandable to 12800) for taking pictures from bright to dim light; improved 63-zone, Dual-layer metering system
Enhanced EOS Film setting together with manual exposure control along with expanded recording 1920 x 1080 (Full High definition)
Wide 3.0-inch Clear View LCD monitor; dedicated Live ViewMovie shooting button
New compatibility with SDXC storage cards, plus brand new menu status indicator for Eye-Fi support



Nikon D7000



Third up in the list of the top 5 highest rated digital camera models is the Nikon D7000, not to be confused with the D700 that we mentioned above.



Features:
High Resolution 16.2 Megapixel DX-format CMOS sensor
Body only; lenses sold independently
High-speed 6 frames per second continual shooting up to a hundred images
Amazing Full 1080p High-definition Movies using Full Time Auto-focus
Dynamic ISO range from 100 to 6400



Nikon D3100



Okay, fourth in our listing of the top 5 best ranked cameras is the Nikon D3100 Rush Tre'Davious White Jersey , which you may have heard talked about in the video review regarding the D7000 above.



Features:
14.2-megapixel DX-format CMOS photo sensor; 3-inch monitor together with One-Touch Live View picture taking as well as video capture
