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.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
