This news or article is intended for readers with certain scientific or professional knowledge in the field. Researchers here provide evidence to indicate that increased expression of CD47 in aged blood vessels impairs a range of functions, from maintenance of these tissues to the generation of new blood vessels. The latter point is interesting given...
by University of Alabama at Birmingham Precision medicine in cancer treatment uses genetic changes in the cancer cells to select the best therapies for individual patients. Now researchers led by James Bibb, Ph.D., professor of surgery at the University of Alabama at Birmingham, suggest using a broader lens of post-translational modification analysis to identify new...
Botox is a muscle-relaxing toxin used cosmetically and for other purposes Researchers mined a US database of side-effects experienced from medications Patients given Botox were compared with those using alternative treatments The team found that the former were 40–88% less likely to report depression Further tests will be needed to confirm if and how Botox...
by Sara Lajeunesse, Pennsylvania State University L-type calcium channel blockers (LCCBs)—the most widely used drugs for treating hypertension—may harm the heart as much as help it, according to a new study. The research team, led by Penn State, found that in rats and human cells in vitro, LCCBs cause changes in blood vessels—known as vascular...

For hundreds and hundreds of years people have tried to stop the aging process. However, their efforts have never yielded any positive results – there is no youth elixir. Even with the latest scientific advancement we cannot stop the damage that time does on our bodies. But now scientists from Saarland University have figured out...
By Heidi Ledford, Nature magazine on June 25, 2020 A suite of experiments that use the gene-editing tool CRISPR–Cas9 to modify human embryos have revealed how the process can make large, unwanted changes to the genome at or near the target site. The studies were published this month on the preprint server bioRxiv, and have...
by University of Leeds The blood flow in the surface blood vessels of a mouse that was not treated with M-3. Drugs that were developed to treat Alzheimer’s Disease could be re-purposed to prevent—or even reverse—the damage done to the blood vessels in people who are obese or suffer from type 2 diabetes, according to...
