Why is it mandatory to test for hepatitis B and C when donating blood? Medical science says that hepatitis B and C infection can be transmitted through blood, so before giving blood to the patient, it is mandatory to test these viruses. Millions of patients around the world are given blood to save their lives. Surgery, accidents, childbirth, cancer, thalassemia, anemia - in all these cases blood is vital. But if this life-giving blood carries the hepatitis 'B' or 'C' virus, it can become a silent risk rather than a life saver.

How are some people's brains able to fight off Alzheimer's disease? Why do some people have the biological signs and damage of Alzheimer's disease , but their memory and intellectual abilities do not decline? Scientists have discovered the answer to this question. Why do some people have the biological signs and damage of Alzheimer's disease, but their memory and intellectual abilities do not decline? Scientists have discovered the answer to this question. According to researchers at the Netherlands Institute for Neuroscience , a rare and special type of immature cells in the brains of such people manage to survive and fight off the damage of the disease, so they do not show symptoms of Alzheimer's. The discovery, published in the journal Cell Stem Cell , raises hopes for the development of completely new treatments to slow the progression of dementia and preserve memory. Why does Alzheimer's disease affect people differently? This has always been a great myst...
