Jacek Rusiecki, traumatologist at San Roque University Hospitals in Lanzarote, explains the new procedures associated with cartilage regeneration. Go to download Osteoarthritis has traditionally been considered a non-inflammatory disease of slow and irreversible progression with destruction of articular cartilage, but, as Jacek Rusiecki, traumatologist at San Roque University Hospitals in Lanzarote, points out, today it is considered more as a biomolecular process. Thanks to this change in conception, research has been developed on how to stimulate natural regeneration, either through platelet growth factors or through stem cells. What it is about, Rusiecki points out, is protecting the joint so that it does not suffer from advanced osteoarthritis. Platelets, stem cells and double sample surgery The treatments are applied by traumatologists, rheumatologists or rehabilitation doctors.
In the case of platelets, by extracting blood from the patient, which once centrifuged produces a plasma rich in platelets that can be applied intra-articularly, reducing the inflammatory process. In more advanced cases, bone infiltration can be used. In the case of stem cell treatments, a sample of bone marrow or fatty tissue is removed. Centrifugation is also done to isolate the cells that WhatsApp Number List are subsequently implanted in the joint. An additional option is the so-called double-stage surgery, in which part of the undamaged cartilage is removed, which, once cultured, forms a collagen membrane that can be transplanted to the patient.The first currency used in the Canary Islands discovered First currency used in the Canary Islands | Photo: Santiago Medina First currency used in the Canary Islands | Photo: Santiago Medina Santiago Medina Gil, businessman and numismatics fan, has taken thirty years to prove that it was minted in Seville in 1513. Go to download The discovery of the first coin used in the Canary Islands began as is usual in historiographic work: by chance.
The eighties, Santiago Medina made one of his regular visits to a market in Las Palmas de Gran Canaria and acquired several pieces in poor condition without knowing that among them was the first used on the islands: “You could almost say that it was the coin that located me.” What he thought was a weekend's work turned into more than thirty years of study to decipher it, both due to the poor level of conservation and the lack of documentation. Sevilla, 1553 By pulling the thread he was able to locate a document that referred to the minting of coins in Seville for the entire Archipelago. Years later, other documents appeared indicating that this coin had been minted in the capital of Seville in 1513, files that also described how the pieces should be minted. All the details matched those he had found. Medina indicates that many of these pieces retained their value until 1775, due to the scarcity of coins and the enormous amount of counterfeit coins that circulated then.
