| Fishing for new source of proteoglycans, an important health food ingredient Posted: 26 May 2022 08:28 AM PDT Chondroitin sulfate proteoglycans (CSPGs), commonly obtained from salmon nasal cartilage, are a key ingredient of various health foods. As the popularity of health foods increases, scientists are searching for alternative sources of CSPGs. Now, researchers have analyzed the PGs and their CS structures in the head cartilage of 10 edible bony fishes, including sturgeons. Their findings point to several new fishes that can serve as alternatives to salmon as a source of CSPGs. |
| Drug resistance molecule can spread though bacterial 'communities' Posted: 26 May 2022 08:28 AM PDT DNA molecules called plasmids -- some of which protect bacteria from antibiotics -- can spread rapidly through bacterial 'communities' that are treated with antibiotics, new research shows. |
| Breathing to win: Scientists show importance of screening breathing patterns in athletic populations Posted: 26 May 2022 08:28 AM PDT Dysfunctional breathing patterns are associated with a high risk of musculoskeletal conditions, resulting in poor physical performance. Now, a study has found that among athletes across age groups, there is a high prevalence of dysfunctional breathing patterns. Effective intervention strategies are required to restore normal breathing patterns and prevent injuries among athletes to ensure their superior performance and health. |

| Inappropriate antibiotics for nonhospitalized kids cost US at least $74 million Posted: 26 May 2022 08:27 AM PDT Children who were prescribed antibiotics inappropriately were more likely to develop complications such as diarrhea and skin rashes than children who were treated according to medical guidelines, according to a new study. This misuse of antibiotics resulted in at least $74 million in excess health-care costs in the U.S. in 2017. |
| Harnessing the immune system to treat traumatic brain injury in mice Posted: 26 May 2022 08:27 AM PDT Researchers have designed a targeted therapeutic treatment that restricts brain inflammation. The effectiveness of this approach in improving outcomes was demonstrated following brain injury, stroke or multiple sclerosis in mice. The system increases the number of regulatory T cells, mediators of the immune system's anti-inflammatory response, in the brain. By boosting the number of T regulatory cells in the brain, the researchers were able to prevent the death of brain tissue in mice following injury and the mice performed better in cognitive tests. The treatment has a high potential for use in patients with traumatic brain injury, with few alternatives currently available to prevent harmful neuroinflammation. |
| Gut bacteria can make blood pressure medication less effective Posted: 26 May 2022 06:56 AM PDT Hypertension, or high blood pressure, is a major risk factor for heart disease and stroke, two of the leading causes of death in America. It's also one of the most common chronic conditions in the United States, with nearly half of U.S. adults considered hypertensive under current guidelines. Among those with high blood pressure, an estimated 20% have what's known as resistant hypertension, meaning their blood pressure remains high despite aggressive treatment. New research has shown gut bacteria can reduce the effectiveness of certain blood pressure drugs, potentially providing a pathway to developing new ways of overcoming treatment-resistant hypertension. |
| Tsunami threats underestimated in current models Posted: 26 May 2022 06:56 AM PDT USC researchers have found a correlation between tsunami severity and the width of the outer wedge -- the area between the continental shelf and deep trenches where large tsunamis emerge -- that helps explain how underwater seismic events generate large tsunamis. |
