Scientists from Saint Petersburg Institute for Informatics and Automation (SPII) have developed an appliance for remote identification of an injured person in cases of emergency.
Abovementioned remote identification system can be extremely useful when delivering emergency and target medical aid under conditions of military operations, catastrophes, disasters and natural calamities. Said remote identification system includes a miniature gadget, which may look like a bracelet, a ring or a medallion not disturbing its owner in his normal life. This gadget is the key element of the system described – its developers have given it the name of passive tele-identifier (PTI). The system also comprises a compact computer (notebook or laptop type) radar attachment. The passive tele-identifier keeps all necessary “conservative” information about system owner – his first and last names, blood parameters and some other data, as well as current information on his organism’s state: cardiac rate, temperature, arterial blood pressure and other parameters. This kind of information can be picked up remotely numerous times without any involvement of a system owner. System developers consider their invention to contribute to effective arrangements for searching injured ones, delivery of prompt and correct medical aid, notification of victims’ family members and even improvement of insurance companies' activities.
Research fellows from the Institute of Biochemical Physics (Russian Academy of Sciences) have come out with an innovation – they have developed a brand new adsorbing agent for cigarettes – known as “Oncosorb”. Said adsorbing agent is an aluminosilicate carrier (alumosilicates are feldspars, mica, clay minerals and other substances), modified with an organo-silicon compound. Developers claim their innovation to possess high efficiency of adsorbing nicotine and carcinogenic agents, such as volatile nitrosamines, polynuclear aromatic hydrocarbons (PAHs), resins and metals, from tobacco smoke.
Scientists from Russian State Medical University (Moscow) suggested using skin health parameters as noninvasive (without any intervention to human organism) indicators of human organism’s ageing. Skin ageing signs are easily detected, but no methods for their quantitative estimation, which can become biological markers of the whole organism’s ageing, currently exist. Researchers have suggested using skin’s ability to fluoresce under irradiation with light of near-ultraviolet region. Skin native fluorescence was measured by means of a fluorimeter on the very tips of hand finger pads. The experiments have shown good correlation between skin fluorescence intensity growth (wavelength range of 420-480 nm) and chronological age between 20 and 70 years.
However, some diseases appear to affect skin fluorescence intensity. For instance, liquidators of the Chernobyl disaster, whom were aged less than 43 years to the moment of the experiment, have showed accelerated skin fluorescence intensity growth with time. Another example of accelerated skin fluorescence intensity growth was detected in case of children with insulin-dependent diabetes.
