Unlocking the mystery behind skeletal aging

New Edith Cowan University (ECU) research has found that exercise not only has physical benefits for men with prostate cancer, it also helps reduce symptoms of depression and anxiety. Up to one in four men experience anxiety either before or after prostate cancer treatment and up to one in five report depression, although few men access the support they need. The study, published in the Nature journal Prostate Cancer and Prostatic Diseases, is the first randomised controlled trial to examine the long-term effects of different exercise on psychological distress in men with prostate cancer undergoing androgen deprivation therapy (ADT). Researchers randomly selected 135 prostate cancer patients aged ...

WASHINGTON, February 16, 2021 -- Research into 3D bioprinting has grown rapidly in recent years as scientists seek to re-create the structure and function of complex biological systems from human tissues to entire organs. The most popular 3D printing approach uses a solution of biological material or bioink that is loaded into a syringe pump extruder and deposited in a layer-by-layer fashion to build the 3D object. Gravity, however, can distort the soft and liquid bioinks used in this method. In APL Bioengineering, by AIP Publishing, researchers from Carnegie Mellon University provide perspective on the Freefrom Reversible Embedding of Suspended Hydrogels ...

What The Study Did: The observational study examined associations between maternal cardiovascular health during pregnancy (as measured by body mass index, blood pressure, total cholesterol level, glucose level and smoking) with the later cardiovascular health of their offspring at ages 10 to 14 years old (as measured by body mass index, blood pressure, total cholesterol level and glucose level).

Spending on low-value health care among fee-for-service Medicare recipients dropped only marginally from 2014 to 2018, despite both a national campaign to better educate clinicians and increasing use of payment revisions that discourage wasteful care, according to a new RAND Corporation study. Three items accounted for two-thirds of the low-value care. Among these, prescribing opioids for acute back pain increased despite a growing national awareness of the harms caused by the drugs and the role of such prescribing in fueling the nation's opioid ...

WASHINGTON, February 16, 2021 -- The widespread use of high-speed and high-energy weapons in modern warfare has led to an increasing incidence of explosive injuries. For such wounds as well as those incurred in disasters and accidents, severe hemorrhage is the leading cause of death. In APL Bioengineering, by AIP Publishing, researchers from the Southern University of Science and Technology in China examine the advances in hydrogel dressings in recent years, which are good at promoting wound healing and can better meet the demands of different situations. "With the rapid developments of material science, there are numerous highly ...

CHICAGO --- A mother's heart health while she is pregnant may have a significant impact on her child's cardiovascular health in early adolescence (ages 10 to 14), according to a new study from Northwestern Medicine and the Ann & Robert H. Lurie Children's Hospital of Chicago. The study will be published Feb. 16 in the Journal of the American Medical Association (JAMA). It is the first study to examine the implications of a mother's cardiovascular health during pregnancy for offspring health in the longer term. The findings are troubling, as they build upon previous Northwestern Medicine and Lurie Children's Hospital research that found ...

Researchers have discovered that the use of Cytoglobin (CYGB) as an intravenous drug could delay liver fibrosis progression in mice. CYGB, discovered in 2001 by Professor Norifumi Kawada, is present in hepatic stellate cells, the cells that produce fibrotic molecules such as collagens when the liver has acute or chronic inflammation induced by different etiologies. The enhancement of CYGB on these cells or the injection of recombinant CYGB has the effect of suppressing liver damage and cirrhosis. These findings published in the February 2021 issue of the journal Hepatology. Anti-fibrotic therapy remains an unmet medical need in human chronic liver diseases. A research team led by Professor Norifumi Kawada, Osaka City University ...

Dry and cloudless weather was mainly responsible for the unusually high solar irradiance in western Europe during the spring of 2020, not the reduction in aerosol emissions due to the first lockdown. This was the result of an international meteorological study, in which scientists from the University of Cologne participated. The results have been published in the current issue of Nature Communications Earth & Environment. A large part of western Europe experienced exceptionally sunny and dry weather from March 23 to the end of May 2020. New sunshine extremes were reported in the United Kingdom, Belgium, Germany, and the Netherlands, coupled with exceptionally deep blue skies. At the same time, these countries had gone into lockdown in response ...
