Researchers found that injuries sustained during menstruation took three times longer to recover from than injuries that occurred on non-bleeding days.Image credit: © iStock.com, skynesherMonthly hormone fluctuations associated with the menstrual cycle affect multiple aspects of women’s bodies, from metabolism and the cardiovascular system to neuromuscular functions.1 Because the menstrual cycle has such a significant effect on physiology, researchers have long wondered how it affects female athletes and their risk of injury.In a new study, researchers followed 33 professional female football (soccer) players over the course of four athletic seasons in Spain’s Liga F, tracking their periods and injuries.2 The scientists…

mRNA molecule, illustration. [Kateryna Kon/Science Photo Library/Getty Images] Messenger RNA (mRNA) has already transformed medicine, most notably through COVID‑19 vaccines that taught cells to act as “protein factories” producing protective molecules. But while vaccines succeed without needing to control which cells make the protein, cancer therapies demand far greater precision: the treatment must hit tumor cells while sparing healthy tissue. Achieving that selectivity has been a major challenge with current lipid nanoparticle (LNP) delivery systems. A new study titled “A tumor-selective mRNA system enables precision cancer treatment,” and published in Molecular Therapy, introduces a breakthrough approach building on lessons from…

Preventive health offering combines ‘microdosed’ GLP-1 meds with biomarker monitoring and behavior change guidance. Digital health platform Noom is broadening its business beyond weight management with today’s launch of a preventive health and longevity program that combines microdoses of GLP-1 medication with behavior change and biomarker monitoring. The new program reflects the company’s strategic shift toward addressing metabolic and cardiovascular risk earlier, targeting people who may not meet traditional criteria for obesity treatment but show biological signs associated with future disease. “The problem we’re solving is that most Americans are living with suboptimal health – and their blood biomarkers show…

Credit: Teal Health We all have medical tests done at some point in our lives. However, busy schedules, needle phobia, embarrassment, and sometimes poor accessibility of testing facilities means that we avoid getting essential tests more often than we should. A survey published earlier this year by Aflac, a U.S. medical insurance company, suggests as many as 90% of Americans have put off at least one medical test that could have serious health consequences if delayed, like screening for cancer. The COVID-19 pandemic opened the door to widespread, non-invasive testing. Many of us used saliva-based, lateral flow antigen tests on…

A heart surgeon and heart attack survivor shares the habits you must ditch for a healthier, longer life and better heart health. When it comes to heart health advice, most of us tune out generic warnings… until it hits too close to home. Dr Jeremy London knows this better than anyone. A veteran US heart surgeon who has repaired dozens of hearts, he nearly lost his own after dismissing what he thought was nothing more than “acid reflux” and fatigue. That close call – a 99% blocked artery – forced him to confront the uncomfortable truth: knowing what’s good for…

Point-of-care (POC) testing and diagnostics for diseases or other medical conditions are common. They include at-home testing such as glucose monitors, pregnancy tests, and the COVID-19 rapid antigen test. In a clinical setting, doctors have at their disposal quick tests for strep throat, prothrombin time tests to monitor blood clotting for patients taking the anticoagulant warfarin, hemoglobin tests to check for anemia or other blood disorders, and cardiac marker tests that can quickly determine whether a heart attack has occurred during an emergency. Some key characteristics of POC tests are that they provide an answer within minutes or hours, not…

Organoid, illustration. [Juan Gaertner/Science Photo Library/Getty Images] Atelerix, a biotech company working on cell preservation and biological transport with its hydrogel encapsulation technology, entered a partnership with Cherry Biotech, a French company specializing in organ-on-chip and organoid technologies. The initial agreement will explore the integration of Atelerix’s hydrogel technology with Cherry Biotech’s advanced 3D organoid models to facilitate global extended-duration shipment. In collaboration, the companies aim to improve the reliability and consistency of transporting these temperature-sensitive materials without the complications of cold-chain logistics, enabling significant growth and expanded customer access to high-quality, human-relevant preclinical data worldwide. Through an initial 12-month…

In Aging, researchers have described how they removed visceral fat from older male mice by targeting the metabolic regulatory protein CD47. A key regulator of metabolism Visible fat carried around the body is subcutaneous fat. While this kind of fat is obviously not healthy to have in large amounts, it is not as immediately dangerous as visceral fat, which accumulates around organs and drives many metabolic diseases [1]. This metabolic damage is often associated with similar age-related problems [2], including sarcopenia, a loss of muscle mass that leads to frailty [3]. To combat visceral fat, the researchers focus on CD47,…
