The brain is more mechanically connected to the body than previously appreciated, scientists report in Nature Neuroscience. Through a study using mice and simulations, the team found a potential biological mechanism underlying why exercise is thought to benefit brain health: abdominal contractions compress blood vessels connected to the spinal cord and the brain, enabling the organ to gently move within the skull. This swaying facilitates the surrounding cerebrospinal fluid to flow over the brain, potentially washing away neural waste that could cause problems for brain function. https://medicalxpress.com/news/2026-04-hydraulic-brain-body-motion-linked.html Mon, 27 Apr 2026 05:00:05 EDT news696252204 A study used a novel transgenic mouse model (TTP knock-in—TTPKI) that has a moderate elevation of TTP systemically to understand if there is a long-term benefit for bone health, thus contributing towards healthy aging. The research was presented at the 102nd General Session of the IADR, which was held in conjunction with the 53rd Annual Meeting of the American Association for Dental, Oral, and Craniofacial Research and the 48th Annual Meeting of the Canadian Association for Dental Research, on March 13-16, 2024, in New Orleans, LA, U.S.. https://medicalxpress.com/news/2024-03-stability-tristetraprolin-bone-health-frailty.html Tue, 19 Mar 2024 13:53:02 EDT news630075181 Computer scientists have developed a new diagnostic tool using artificial intelligence and a digital camera to detect facial palsy with 98% accuracy, including the patient's gender and age. https://medicalxpress.com/news/2023-11-digital-camera-ai-algorithm-facial.html Thu, 30 Nov 2023 04:35:57 EST news620541354 Cannabidiol (CBD) and cannabigerol (CBG) might someday help bone fracture patients manage their pain, according to a Penn State study. In a study in mice, the researchers unexpectedly found that the cannabinoids also promoted fracture healing. https://medicalxpress.com/news/2023-10-cbd-cbg-bone-fracture-pain.html Thu, 26 Oct 2023 13:37:03 EDT news617546221 By means of experiments in mice, researchers have made discoveries about the mechanisms involved in dental pulp inflammation and root apex damage that pave the way for a search for medications that can be used to inhibit the bone loss due to endodontic infection (in dental pulp, the soft tissue inside teeth). https://medicalxpress.com/news/2023-10-discovery-mechanism-involved-dental-inflammation.html Thu, 05 Oct 2023 11:39:46 EDT news615724783 A defective heart valve is the second most common form of heart disease. Most cases involve a narrowed aortic valve, but often the mitral valve can also be affected. Prostheses significantly increase the life expectancy of those with the disease. While bioprosthetic heart valves have some advantages over mechanical ones, they can become calcified relatively quickly, limiting the length of their useful life. A team of researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS is attempting to prevent such calcification with a new chemical pretreatment of the bioprostheses. https://medicalxpress.com/news/2021-11-calcification-bioprosthetic-heart-valves.html Tue, 02 Nov 2021 09:28:31 EDT news555064107 A team of EPFL engineers has developed technology that could partially restore vision in blind people.

However, it can be tricky to detect this early enough. Researchers at Tohoku University have developed a new method that would allow doctors to detect cancers in the lymph nodes while they are still small, before they travel to other parts of the body. This can greatly increase the chances of a successful treatment. https://medicalxpress.com/news/2019-03-peek-lymph-nodes.html Thu, 14 Mar 2019 08:50:01 EDT news471772039 Research led by Johns Hopkins investigators has uncovered the roles of two types of cells found in the vessel walls of fat tissue and described how these cells may help speed bone repair. https://medicalxpress.com/news/2019-02-cells-bone.html Wed, 20 Feb 2019 09:50:38 EST news469878613 Whether you're pitching a baseball, playing a violin, or typing at your desk, your shoulder helps you get the job done.

To understand what causes this pain, Suresh Mahalingam of Griffith University in Australia and his team studied how RRV affects human and mouse osteoblasts. They found that RRV concentrates in osteoblasts, where it induces the production of inflammatory cytokines. This leads to increased bone loss, which causes pain. The research appears in the Proceedings of the National Academy of Sciences. https://medicalxpress.com/news/2014-04-bone-loss-joint-pain-alphaviral.html Tue, 15 Apr 2014 10:01:25 EDT news316774708 From athletes to individuals suffering from osteoporosis, bone fractures are usually the result of tiny cracks accumulating over time—invisible rivulets of damage that, when coalesced, lead to that painful break. https://medicalxpress.com/news/2013-03-illuminating-fractures-x-ray-imaging-bone.html Thu, 07 Mar 2013 13:40:02 EST news281885161 (AP)—Zac Vawter considers himself a test pilot.
