The body’ human tear glands that “shed tears” sound like something out of a sci-fi movie. But researchers from the Hubrecht Institute and UMC Utrecht used stem cells to grow tiny tear glands in Petri dishes to mimic the real thing. They hope these so-called organisms could serve as models for studying how human tear-laden cells produce tears. Their ultimate goal is to better understand and treat diseases such as dry eye disease or autoimmune disease dryness syndrome and tear…

A new study suggests that electrical stimulation may help blood vessels deliver white blood cells and oxygen to the wound to speed up healing, foreign media reported. The latest study, published in Royal Society of Journal Labs on a Chip, found that stable electrical stimulation can increase the permeability of blood vessels and provide new insights into how new blood vessels grow. It is understood that in the case of fluid flow, electrical stimulation provides a constant voltage and accompanied…

A mouse study showed that the genetic part of the anxiety is mediated by the gut microbiome. Anxiety is already the most common mental illness in many countries, including the United States, and the prevalence of anxiety disorders has increased dramatically during the new pandemic. The study, led by researchers in the field of biological sciences at Berkeley Labs and published in Scientific Reports, provides evidence that taking care of our gut microbiome may help alleviate some anxiety. The team…

Russian futurist Evgeny Kuznetsov told the satellite news agency that editing human genes to eliminate terminal illness and extend life expectancy will become a trend in 20 years. Kuznetsov said: “By editing genes to transform humans, this is an extremely powerful tool, it can not only be used for the treatment of rare diseases and prolong life but also for infants to design, for example, the choice of eye color.” The ethics and medicine of this issue are completely unclear,…
