High Probability Diagnostics

21.06.2002


A lot of diseases are known to the medical science, each of the diseases having its own symptoms. Nevertheless, all diseases have something in common, regardless of the illness cause and the patients` individual reactions. These generalised regularities inherent in all diseases are called general pathology. Physicians can easily recognise anatomical and physiological abnormalities, but some symptoms are not evident. These abnormalities appear to be a presage of a disease, and after the recovery they are retained for some time by the organism as a reminder of the disease. The signs of such asymptomatic pathology are, brought to light, with the help of biochemical, immunological, biophysical, molecular-biological and molecular-genetic research. For twenty years the staff of the Medical Genetic Research Center (Russian Academy of Medical Sciences) have been researching various latent signs of general pathology comparing the value of information they carry. The scientists have come to the conclusion that some, specific leukocytes` proteins are more sensitive.



The leukocytes genome reacts violently to the pathological state of the organism, as a result it changes the content of proteins called 53? and 43? in these cells. In fact, the indication of general illness is the ratio of these proteins content to the content of the histon protein of leukocytes. The scientists have examined 1,672 patients suffering from different types of various diseases, both heritable and acquired, including phenylketonuria, Down`s syndrome, psoriasis, stomach ulcer, bronchial asthma, oncological diseases, hepatitis, herpes, tuberculosis and many others. The researchers have also focused on the radiation sickness, cardiovascular diseases, illnesses of kidneys, liver and bile-ducts, tumours, diseases of bones and joints and gastrointestinal tract. Without exception, the ratio of proteins of all the examined patients has turned out abnormal. This implies high probability diagnostics - nobody has managed yet to achieve one-hundred-percent diagnostics.

Up to now the pre-clinical diagnostics used other indications, for instance, the scientists determined the concentration of various cell types or the content of antibodies and some other substances in blood. However, these indications may fail the diagnostics as they do not show up with all diseases or with all patients. The 53K and 43K proteins relative content has never failed the researchers. There exist other signs of general pathology, which can be determined by a physician. These signs can include oedema, pathologies of blood circulation, thrombosis, inflammation and some others. However, it is not easy to use these signs for the early diagnostics purposes, since with different individuals and at different phases of illness development these signs do not only reflect the pathological process but also indicate the adaptive response of the organism.


Having compared the suggested pre-clinical and post-clinical diagnostics methods, with other methods being employed now, the Moscow scientists believe that the protein parameters of leukocytes may be considered the `gold standard` in the general pathology recognition. Having determined that the pathology takes place, the doctors should send potential patients to the examination to define the disease more precisely and to undertake the required measures. The above analysis is not that laborious. According to the researchers, it makes sense to carry out the analysis to reveal the new-born children`s pathology, and to apply this method to undertake health checks of the people who are living or working in unhealthy conditions. This method can help to monitor the disease dynamics and to check the treatment efficiency, to validate whether the treatment is successful and whether it does not cause any harm. The general pathology early diagnostics is also helpful for the people with hereditary predisposition to illnesses, and for clinical tests of new drugs in order to determine contra-indications to a certain medicine.

Im Focus: Making Waves

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.

Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
