A new research from Switzerland suggests that a substance extracted from brown algae could potentially treat osteoarthritis. The research was led by Professor Marcy Zenobi-Wong from the Eidgenössische Technische Hochschule (ETH), and Dr. Katharina Maniura, from Empa.
With the help of the experiments in vitro, the scientists discovered that polysaccharide alginate derivatives extracted from the stems of brown algae Laminaria hyperborean can strop joint cartilage deterioration.
The researchers believe that development of a clinical solution target the condition itself, not its symptoms, would greatly improve the quality of life, as well as allow people with the disease to avoid complications that one day could lead to disability and surgery of joint replacement.
A recent research discovered that nowadays knee arthritis is more than twice as common as it used to be only a few generations ago. Scientists say that the risk of developing the condition is 46% now.
Dr. Jordan Metzl, a sports medicine physician at New York’s Hospital for Special Surgery, says that this phenomenon could be influenced by inactivity of modern life. The study demonstrates that cases of developing arthritis more than doubled these days.
Dr. Metzl explains: “The best thing to do is strengthen your muscles with exercises like squats and lunges instead of saying off of the knee and, in effect, becoming more inactive.
A new research, which was a collaborative effort of researchers from Tufts University in Boston, USA, and the University of Manchester, UK, demonstrates that diet rich in fiber may cut the risk of developing osteoarthritis.
For the study, the researchers completed a meta-analysis of two long-term studies on the benefits of diets rich in fiber. The scientists found that the participants who consumed the most fiber had a 30% lower risk of osteoarthritis in OAI cohort, and 61% lower risk of OA in the Framingham cohort, compared with people who ate the least fiber.
Dr. Zhaoli Dai, a lead researcher of the study of the Human Nutrition Research Center on Aging and Friedman School of Nutrition Science and Policy at Tufts University, says: “Findings from two longitudinal studies consistently showed that higher total fiber intake was related to a lower risk of [symptomatic], while the relation to [incident radiographic OA] was unclear.”
Usually, running causes discomfort in joints while running, and running for long distances is believed to be bad for knees. Nevertheless, a new study, conducted by exercise science professors from Brigham Young University, found that molecules causing knee joint inflammation essentially reduce after running.
For their study, the researchers collected the Synovial fluid and serum samples from knee joints of 6 healthy leisure runners aged from 18 to 35, before and after they ran for 30 minutes. The results showed that the cytokines GM-CSF and IL-15 that cause inflammation decreased in levels after running and remained at the same level in a non-running state.
Matt Seeley, the study co-author, said in a press release: “This study does not indicate that distance runners are any more likely to get osteoarthritis than any other person. Instead, this study suggests exercise can be a type of medicine.”
A new technique of repairing damaged knees is developed by the University of Basel in Switzerland. The damaged knees have been repaired with the help of the cartilage from a patient’s own nose for the first time. This procedure can totally transform arthritis treatment.
Osteoarthritis occurs when the knees of hip wears out, leaving bone rubbing on bone. And the cartilage cannot repair itself as it doesn’t have its own blood supply. Ten patients with severe knee injuries have undergone the new therapy, and nine of them were showing significant improvements in movement and quality of life.
Stephen Simpson, the director of research at Arthritis Research UK, says: “Thee study gives us hope of finding further treatment options for people with osteoarthritis.”
