This artificial kidney could replace dialysis | Digital Trends Spanish

Researchers in the United States develop an artificial kidney that could prevent people living with kidney disease from needing a dialysis machine. It would also help all long-standing transplant patients. This initiative is known as Project Kidney and is spearheaded by scientists from the University of California, San Francisco. The team in charge combined the two essential parts of their artificial kidney, the hemofilter and the bioreactor, and succeeded in implanting the device the size of a smartphone for its preclinical evaluation. In recent years, scientists have successfully tested the hemofilter, which removes waste products and toxins from the blood, and the bioreactor, which replicates other kidney functions, such as electrolyte balance. "The vision of the artificial kidney i...

Dried blood could help detect doping in Tokyo 2020 | Digital Trends Spanish

The University of Copenhagen developed a method that, using drops of blood, can easily and effectively detect whether an athlete has used performance-enhancing drugs. This method has already been approved by the World Anti-Doping Agency (WADA) and could be tested at the Tokyo Olympics. "The method involves pricking an athlete's finger or upper arm with a needle and quickly collecting a few drops of blood on a piece of filter paper," explains Sara Amalie Solheim, current Scientific Advisor to Anti-Doping Denmark. “The dried blood drops are then analyzed in a laboratory for doping substances. The method is smart because it is faster, less painful and less intimidating than traditional blood and urine tests.

A protein protects the “fountain of youth” of the blood | Digital Trends Spanish

Scientists discovered a key protein that supports the production of healthy blood cells throughout the life cycle, regulating the body's inflammatory response. This is the first study to reveal a protein that plays a crucial role in protecting blood stem cells, which continually produce the blood and immune cells necessary to prevent premature aging. The discovery shows that the protein, known as YTHDF2, protects these stem cells from damage when the body is fighting an infection and allows them to continue to function properly. Scientists have long been puzzled about how these cells, known as hematopoietic stem cells, protect themselves from exhaustion while increasing the production of immune cells to fight infection. Previous studies had determined the protein YTHDF2 plays an im...

Aspirin to get COVID-19 patients back? | Digital Trends Spanish

Several studies have shown that almost 80% of patients who die due to COVID-19 have thrombosis or blood clotting in the lungs. A group of researchers believe that blood thinners, such as aspirin, could help prevent this critical clotting that can lead to the death of a person. For this reason, they will begin to give aspirin to patients infected with coronavirus who are recovering in a British hospital, as part of a trial that seeks to determine if this drug can prevent deadly blood clotting in the lungs. If its effectiveness can be proven, it would be the first over-the-counter drug that has actually been shown to have an impact on the coronavirus. "Aspirin is a very available and inexpensive drug, and if it worked, it would be a huge boost for treatment," says Oxford University p...
