Succinyl-chitin (SCH) nanoparticles were obtained by acylation of partially deacetylated chitin (DCH) nanofibers. Introduction of the succinyl moiety induced a partial amorphization of DCH, as viewed by X-ray diffraction, and increased the fractal dimension of the colloids from d = 1.2 (DCH) to 1.

Aim: To determine predictors of remote outcomes of complex combat brain injury.

Material And Methods: A survey of 145 combatants with long-term combat injury (from 1 to 10 years) was conducted. Responses were received from 30 people from 18 regions of the Russian Federation.

The otoprotective effect of immobilized hydrocortisone was studied on the model of acute acoustic injury to the auditory analyzer in male Wistar rats. The effects of true solution and suspension where polyvinylpyrrolidone particles (100-500 nm) served as dispersed phase (hydrocortisone concentration 5 mg/kg). The agents were administered immediately after continuous acoustic stimulation: 5 kHz tone, 110 dB for 2 h.

Despite the increasing use of amorphous silica nanoparticles (SNPs) in biomedical applications, their toxicity after intravenous administration remains a major concern. We investigated the effects of single 7 mg/kg intravenous infusions of 13 nm SNPs on hemodynamic parameters in rats. Hematological and biochemical parameters were assessed at 7, 30, and 60 d post treatment.
