Young human blood, from which blood plasma was obtained and injected in laboratory mice seems to contain rejuvenating properties and showed promise that it could help repair damaged tissues, according to reports published in New Scientist.
Young human blood may be the key to the fountain of youth
The young human blood trials experiment was presented by researchers from a company called Alkaherst, during the last annual meeting in San Diego, California by the Society for Neuroscience. The experiments involved the inoculation of blood plasma taken from 18-year old human volunteers into year-old mice. The lab mice were the age equivalent of 50 years in humans.
After the blood plasma injections, the mice began to show significant improvement in their cognitive performance and were running around like they were just three-months old. Comparative tests also showed marked improvement on memory against lab mice that were not treated.
Plasma is the blood’s primary nutrient and mineral carrier
Blood plasma is the liquid medium that carries the blood cells containing essential salts, minerals and proteins, specifically the types that possess healing and rejuvenating properties, according to the scientists. They, however, did not disclose which specific nutrients they are.
The scientists suggest that the blood plasma injected in mice were responsible for boosting neurogenesis. This is the process by which neurons are being generated mostly in the hippocampus region and vastly responsible for shaping memories.
The researchers believe that this discovery would revolutionize medical advancements in the treatment and therapy of degenerative diseases like Alzheimer’s and Parkinson’s Disease for which no cure has been found. The scientists also believe that this could also help in the development of anti-ageing treatments.
Human blood also the subject of tests to determine effects of antibiotics
In another part of the world, scientists from the University of Freiburg in Germany, made advances in a testing method that can help quantify the amount of antibiotics in the human blood stream.
Unlike traditional diagnostics, the research team found a way to test for the amount of antibiotics in human blood in a matter of minutes patterned after a biological process they aptly called a biosensor system that will help them with measuring antibiotics in the blood.
“The analysis takes only 10 minutes, from sample to result and our study was about demonstrating the applicability of the platform,” said Dr. Can Dincer, who heads the research team in this experiment.
Help determine which antibiotics are in the blood
The wanton use of antibiotics without the benefit of proper medical prescriptions and targeted have been responsible for the development of antibiotic-resistant bacteria also know as superbugs. If antibiotics are not properly used according to the bacteria they are supposed to be targeting, they develop pathogens that build resistance.
“The major advantage of this system is that we can measure up to eight different substances at the same time, quickly and simply,” Dincer adds.
Characteristics in human blood can help diagnose risks of diseases
Meanwhile, a group of scientists discovered that the variation in the characteristic and volume of human blood cells can help determine the level of risk a person may have in contracting complex diseases like cardiac problems, rheumatoid arthritis, asthma, celiac disease and diabetes, among others.
A collaborative study called the BLUEPRINT Project participated by the Wellcome Trust Sanger Institute, published recently in the journal Cell. The 5-year study was participated in by a large group of no less than 42 research institutes, universities and industry leaders in Europe. The primary objective of the study was to explore epigenetic changes that occur in the human bone marrow where stem cells are likely to develop into mature life-giving blood cells.
The study also aimed to correlate genetic differences and epigenetic changes on the physical characteristics of cell types that may give clues to how complex diseases, cancer and blood-related disorders develop.
“When mature red blood cells rupture in our blood the body replaces them with new, young red cells – a process known as haemolysis. So we think that increased haemolysis and increased risk of coronary heart disease are affected by the same biological pathways. Identifying these pathways may offer new treatment possibilities, “says Dr. Adam Butterworth from the University of Cambridge and one of the senior authors of the study.
This, together with several other old and young human blood experiments are in the forefront of the focus for the BLUEPRINT Project with the hope that in the near future, they may be able to harness these breakthroughs that could revolutionize the diagnosis and treatment of diseases and disorders that are yet to see better days with medication and therapy.
