The paper analyses the age structure of mortality from suicide, injuries with undetermined intent in general, as well as hanging or jumping/falling from heights with undetermined intent as a potential indicator of latent suicides. It is shown that the age profile of suicide mortality has fundamentally changed over the last 30 years: during the 1990s crisis, a sigmoidal mortality curve with a peak in middle age developed among men, while at the height of the crisis, in the mid-1990s, the maximum age-specific mortality rates were observed among the 50-54-year-olds. Fundamental gender differences in the age profile were only noted during the systemic crisis of the 1990s: as Russian men developed a sigmoidal suicide mortality curve, the age profile of mortality of Russian women was characterised by a stable increase in age-specific indicators starting from age 25-29, while in the mid-1990s women, too, experienced a mortality peak among the 50-54-year-olds. In the 2000s, a gradual flattening-out of the mortality peak in middle age and reaching a maximum at old age took place. Post-2010, a further normalisation of the suicide mortality profile with formation of a plateau at working ages was observed. A comparative analysis of the age profile of suicide mortality and mortality from hanging and jumping/falling from heights with undetermined intent corroborated the hypothesis of these causes being a potential reservoir of latent suicide, which raises the suicide losses of men, from 80% among the 15-24-year-olds to 50% in older individuals, while among women the suicide mortality rate doubles at all ages above 15 years.

A laser technology for creating nanocomposites from alternating layers of albumin/collagen proteins with two types of single-walled carbon nanotubes (SWCNT) at concentrations of 0.001 and 0.01 wt.% was proposed. For this purpose, a setup with a diode laser (810 nm) and feedback system for controlling the temperature of the area affected by the radiation was developed. Raman spectroscopy was used to determine a decrease in the defectiveness of SWCNT with an increase in their concentration in the nanocomposite due to the formation of branched 3D networks with covalent bonds between nanotubes. It was revealed that adhesion of proteins to branched 3D networks from SWCNT occurred. The specific electrical conductivity of nanocomposites based on large SWCNT nanotubes was 3.2 and 4.3 S/m compared to that for nanocomposites based on small SWCNT with the same concentrations—1.1 and 1.8 S/m. An increase in the concentration and size of nanotubes provides higher porosity of nanocomposites. For small SWCNT-based nanocomposites, a significant number of mesopores up to 50 nm in size and the largest specific surface area and specific pore volume were found. Nanocomposites with small SWCNT (0.001 wt.%) provided the best cardiac fibroblast viability. Such technology can be potentially used to create bioelectronic components or scaffolds for heart tissue engineering.
