As part of a scientific experiment likely to revolutionize cancer detection, British researchers announced yesterday that they were testing an effective way to diagnose patients' breathing. They added that they had developed a device called "respiratory biopsy" (on the biopsy pattern taken from suspected cancer tissue) to monitor volatile particles in the breath.
Researchers at Cancer Research Japan Cancer Research and Olston Medical, designer of the new test instrument, believe the device will make it easier to diagnose early-stage cancers and treat the disease quickly. The tests, called "Early Detection Experiments for All Breathless Cancers", are also conducted by researchers at the University of Cambridge.
Breath analysis
The researchers began their two-year trials at the Edinburgh Hospital in Cambridge with 1,500 healthy and sick people. The first tests will be performed by people suspected of esophageal cancer and stomach, followed by those exposed to cancers of the prostate, kidneys, bladder, liver and pancreas.
Rebecca Fitzgerald, a professor at the Experimental Cancer Research Foundation, said the world urgently needed to develop new tools, such as respiratory tests, to quickly detect cancer. "Through this experience, we hope to monitor the" fingerprints "of cancer in human breath," said the researcher specializing in cancer of the stomach and esophagus.
The test is designed to monitor volatile organic compounds that are released by the breath after being collected and sent to the laboratory for analysis. These compounds come from the cells of the body as part of the process of activity and work, they reach the lungs and are then expressed by breathing.
Scientists say the test aims to monitor trends in the presence of volatile vehicles as well as any anomalies in these trends. To monitor, participants will be asked to breathe in the analyzer for 10 minutes.
"The technology we have designed is particularly effective at monitoring volatile VOCs to detect early stages of cancer," said Billy Boyle, co-founder and general manager of Olston Medical. He added that the use of a breath test as well as blood and urine tests to monitor cancer was very promising. These non-intervention tests can be an effective early detection tool.
Scientists from the Imperial College of Britain and the Karolinska Institute of Sweden presented last year a breathtaking model for monitoring esophageal and stomach cancer. The test detected 80% of cases already infected and confirmed that healthy people were not infected in the same proportions.
According to statistics, 8.8 million people worldwide died of cancer in 2015. Scientists estimate that one in two will develop a type of illness during his lifetime.
Blood for the treatment of Parkinson's disease
Another American medical research company said that she was experimenting with pumping young people into the body of Parkinson's disease.
Alcahist, founded by Tony Wyss-Curray, a researcher at Stanford University, said he had already performed tests by injecting blood into people with Alzheimer's disease. She said that she was testing 90 people with Parkinson's disease caused by neurodegeneration.
Subject to new tests, patients aged 70 to 80 years mainly benefit from our right to blood for 5 consecutive days, then another right after 3 months. The experiments will determine the utility of this therapy by monitoring the progress of memory, attention, language skills and cognitive abilities.
A scientific team comprising Wes-Curay was able to reverse the entire process of deteriorating the intellectual capacity of the mice after the injection of young mice 's blood.
Although researchers do not know why young blood renews the vitality of the pyramidal body, young blood usually generates fresh, refreshing proteins that are not generated by pygmy blood. The American researcher believes that some parts of the blood, a mixture of about 1000 different proteins, contribute to the revitalization of the body pyramid. The researchers were able to reinvigorate the pyramidal mice after injecting these pieces.
