Drug Reverses Alopecia Areata Hair Loss

Drug Reverses Alopecia Areata Hair Loss

Researchers may have found a cure for the baldness caused by alopecia areata, an autoimmune condition that causes patchy hair loss, and it is a drug already on the market, though for the treatment of bone marrow disorders. After just five months of taking ruxolitinib, three alopecia areata patients who had lost at least a third of their hair due to the disorder saw total hair regrowth. Further testing is needed to see if this treatment will be safe and effective on a wider scale. More… Discuss

Supercooling Could Extend Organs’ Viability

Supercooling Could Extend Organs’ Viability

A new technique for “supercooling” organs could preserve donor organs for days, allowing doctors more time to match them to suitable transplant candidates. Currently, doctors have a day or less to get a liver into a recipient, but in tests on rats, the new process kept livers viable for three days, a vast improvement. Rat livers are considerably smaller than human ones—0.35 oz (10 g) compared to 3.3 lb (1.5 kg)—and it remains to be seen whether scientists can scale up the technology and whether it will be able to preserve other organs as well.

Blood from Young Improves Memory in Old

Blood from Young Improves Memory in Old

Transfusing the blood plasma of young mice into older mice allowed them to perform better on tests of memory than their peers, suggesting that some factor or factors in the blood of the young can reverse certain aging processes. Researchers are now trying to identify which factors accomplish this and whether similar benefits would be seen in human trials. More… Discuss

Blood Test Predicts Alzheimer’s

If you could find out today whether or not Alzheimer’s disease is in your future, would you want to? Scientists in the US have developed a blood test that they say can predict with 90 percent accuracy an individual’s risk of developing Alzheimer’s within the next few years. The test looks at the levels of 10 lipids in the blood that appear to be predictive of future cognitive decline. It is unclear why these lipid levels act as an indicator, but one theory is that early changes in the brain affect these circulating fats. Experts are now in the process of confirming and refining these findings. More…Discuss
