Scientists Develop Artificial Blood - Scientists from the University of Sheffield are developing an artificial 'plastic blood´, which could act as a substitute for real blood in emergency situations Because the artificial blood is made from a plastic, it is light to carry and easy to store Donated blood has a relatively short shelf-life of 35 days, after which it must be thrown away The artificial blood is made of plastic molecules that hold an iron atom at their core, just like haemoglobin, that can bind oxygen and could transport it around the body Whole article ScienceDaily (16.5.2007)
Short chromosomes put cancer cells in forced rest - A Johns Hopkins team has stopped in its tracks a form of blood cancer in mice by engineering and inactivating an enzyme, telomerase, thereby shortening the ends of chromosomes, called telomeres "Normally, when telomeres get critically short, the cell commits suicide as a means of protecting the body," says Carol Greider, Ph In an unusual set of experiments, the research team first mated mice with nonoperating telomerase to mice carrying a mutation that predisposed them to Burkitt’s lymphoma, a rare but aggressive cancer of white blood cells Whole article: http://www (27.4.2007)
Hormone-based blood pressure pill possible - The Mayo Clinic scientists said the study supports the feasibility of developing a peptide-based drug that can be given in pill form to lower blood pressure and that is based on a hormone originating in the heart, called B-type natriuretic peptide Our formulation of an oral peptide is a technological accomplishment that really can advance the field," said Dr Whole article: www (4.4.2007)
Sifting Out Cure For HIV: Special Ceramic Membranes Could Filter Virus From Blood -
HIV may one day be able to be filtered from human blood saving the lives of millions of people, thanks to a world-first innovation by Queensland University of Technology scientists
QUT scientists have developed specially designed ceramic membranes for nanofiltration, which are so advanced they have the potential to remove viruses from water, air and blood
Associate Professor Huaiyong Zhu, from QUT's School of Physical and Chemical Sciences, is leading the development of these membranes, also known as nano-mesh, and said preliminary research had proved it successful in removing viruses from water
Nanofiltration is the filtration of minute particles using a filter with extremely small pores
"If we can remove compounds from liquids and viruses from water, then there may also be potential to remove HIV from blood," Dr Zhu said
