The eyes are not only a mirror of a soul, but also a medical record. Their thermal radiation can indicate a disease even before clinical signs appear. Investigations in this area conducted by Russian scientists have been supported by the research program of the Russian Academy of Sciences called “Abstract Sciences for Medicine”.
Russian biophysicists under the guidance of G.R. Ivanitsky, Corresponding Member of the Russian Academy of Sciences, are developing the system for rapid disease diagnostics by eyes thermal radiation. The method may be particularly useful during epidemic when it is necessary to assess promptly the state of health of the people coming from infected regions, this being done directly at railway stations and airports.
Physicians have always taken the patients’ temperature. This is a rather reliable indicator of the state of health, although some diseased are not accompanied by noticeable rise in temperature. The thermometer is usually placed under the tongue, in the armpit, in the external acoustic meatus or the rectum. Such methods do not suit for remote rapid diagnostics of people in a crowd. Instead of a traditional thermometer, Russian researchers suggested to use cameras recording infrared radiation of people, which would allow to take temperature promptly at a distance. Infrared cameras determine the temperature with precision of up to several hundredth of a degree. During mass diagnostics, it is most convenient to take the temperature of face – a constantly open part of the body. The warmest part of the face is eyes. The eye glow more intensely than the skin in the infra-red range, as they contain six hard-working muscles each, a ramified blood supply system and lachrymal glands. The temperature in the vicinity of eyes normally reaches 36.5 degrees C.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
