How to make artificial blood for transfusions

According to U.S. National Heart, Lung and Blood Institute, Red blood cells are common components in blood transfusion.

The cells contain haemoglobin that delivers oxygen to the body tissues, scientists have tried to develop chemically modified haemoglobin.

Blood transmissions can save lives of patients that suffered blood loss in an accident. Hospital may not have the right type of blood, scientists have discovered a new method of producing substitute blood to save lives.

Researchers wrapped haemoglobin in polydopamine and test it in the laboratory, it shows polydopamine haemoglobin carrying oxygen effectively and it also prevents methaemoglobin and hydrogen peroxide.

The blood formed-polidopamine haemoglobin, caused minimum cell damage and served as an effective antioxidant. It removes damaging free radicals and reactive oxygen species.

Effects of Zika virus on your heart

Zika virus is primarily transmitted  through the bite of an infected Aedes mosquitoes. Centers for Disease Control and Prevention (CDC) has confirmed that Zika can spread through sex, infected blood during transfusion and pregnant mother to foetus.

This virus could harm the heart by damaging the  heart muscle cells or by promoting inflammation in the heart of infected people, Zika is also linked to autoimmune disorder that causes muscle weakness and paralysis.

People infected with zika virus should get enough rest, drink enough water and seek medical care, presently there is no vaccine available for zika virus.

Zika can be prevented by wearing light- coloured clothes that cover every parts of the body and sleeping inside insecticide treated mosquito net.
