A research team has discovered a new mechanism and drug combination strategy that can effectively treat osteoporosis, a representative disease of super-aging societies. The research findings were published on April 2 in Bone Research. The researchers were led by Seoul National University College of Engineering's Prof. Sunghoon Kwon and Prof. Sang Wan Kim. https://medicalxpress.com/news/2026-04-laser-breakthrough-supercharges-osteoporosis-treatment.html Tue, 14 Apr 2026 14:40:04 EDT news695394053 New research from Flinders University has revealed that parents are feeling conflicted, confused and concerned when it comes to zero-alcohol beer, wine and spirts and adolescents. https://medicalxpress.com/news/2024-03-proceed-caution-meteoric-alcohol.html Mon, 04 Mar 2024 16:18:03 EST news628791481 The word 'evolution' may bring to mind dusty dinosaur bones, but it impacts our health every day. For example, even though antibiotics were invented only a century ago, the evolution of antibiotic resistance is already a major concern. The rise in modern health problems such as obesity can also be traced back to evolutionary principles. https://medicalxpress.com/news/2023-02-anti-antibiotics-extinction-therapy-evolutionary-medicine.html Tue, 28 Feb 2023 14:19:04 EST news596816341 Patients with heart failure with reduced ejection fraction (HFrEF) did not experience any improvement in their ability to exercise vigorously after taking the experimental heart failure drug omecamtiv mecarbil, in a study presented at the American College of Cardiology's 71st Annual Scientific Session. https://medicalxpress.com/news/2022-04-omecamtiv-mecarbil-capacity-heart-failure.html Mon, 04 Apr 2022 09:20:06 EDT news568282802 The number of confirmed coronavirus cases in Iran passed the two-million mark Thursday, while the daily caseload set a new record high in what a health official warned amounted to a "meteoric" spike. https://medicalxpress.com/news/2021-04-covid-cases-million-iran-meteoric.html Thu, 08 Apr 2021 11:04:35 EDT news537098671 What causes cancer? Smoking, certainly, and also things like sun and chemical exposure. Cancer risk also increases with some genetic predispositions and in old age. One thread connecting these risks is genetic mutations in the cells of our bodies - smoking and UV exposure increase the rate of DNA damage and with each replication of damaged DNA comes the chance of picking up a random mutation that can kickstart cancer. And the longer we live, the more chance that awful luck will result in one of these random, cancer-causing mutations. This is the mutation accumulation theory of oncogenesis: "Cancers are caused by mutations that may be inherited, induced by environmental factors, or result from DNA replication error," write John Hopkins University biostatisticians Tomasetti, Li and Vogelstein in the March 24, 2017 issue of the journal Science. https://medicalxpress.com/news/2017-07-refuting-idea-mutations-cancer.html Mon, 31 Jul 2017 15:06:07 EDT news420732318 Vienna, Austria: Patients with advanced kidney cancer live for nearly twice as long without their disease progressing if they are treated with cabozantinib, a drug that inhibits the action of tyrosine kinases - enzymes that function as an "on" or "off" switch in many cellular processes, including cancer. https://medicalxpress.com/news/2015-09-cabozantinib-survival-patients-advanced-kidney.html Fri, 25 Sep 2015 18:49:03 EDT news362425734 A paper published today in the Proceedings of the National Academy of Sciences argues against the commonly held "accumulation of mutations" model of oncogenesis in favor of a model that depends on evolutionary pressures acting on populations of cells. Basically, the paper states that the ecosystem of a healthy tissue landscape lets healthy cells outcompete ones with cancerous mutations; it is when the tissue ecosystem changes due to aging, smoking, or other stressors, that cells with cancerous mutations can suddenly find themselves the most fit, allowing their population to expand over generations of natural selection. https://medicalxpress.com/news/2015-07-evolution-mutation-cancer.html Tue, 21 Jul 2015 13:22:01 EDT news356703710 Cancers are age-related, much more frequent in the old than in the young. A University of Colorado Cancer Center review published today in the journal Oncogene argues against the conventional wisdom that the accumulation of cancer-causing mutations leads to more cancer in older people, instead positing that it is the changing features of tissue in old age that promote higher cancer rates in the elderly. https://medicalxpress.com/news/2012-07-cancer-age.html Mon, 02 Jul 2012 08:11:45 EDT news260435498
