[On the relevance of examining the internal organs for the presence of diatom plankton after drowning at sea].

Objective: To establish the relevance of examining the internal organs for the presence of diatom plankton after drowning in the waters of the White Sea.

Material And Methods: We studied the biological material (fragments of lungs and kidneys) from the corpses of people found in the waters of the Kemskaya Bay and Onega Bay of the White Sea and waters from different areas of the White Sea for the presence of diatoms.

Results: In all cases of drowning in the waters of the White Sea (in the area of the city of Belomorsk and the Kem skerries), marine and freshwater diatoms were found in the lungs and kidneys of the deceased in quantities sufficient to diagnose death from drowning in water.

Proteomic analysis of nontuberculous bacteria protein spectra as the element of subtyping of strains.

Background: For the present, matrix-assisted laser desorption/ionization-time-of-flight (MALDI-ToF) mass spectrometry is the fastest and the most correct method for species identification of microorganisms. Apart from species-level identification, it allows to use a variety of approaches for the analysis and comparison of protein spectra of microorganisms of the same species, which are isolated from a patient at various disease states, that can be used in routine microbiological practice in laboratories fitted with mass analyzers.

Methods: Two strains of Mycobacterium fortuitum and two strains of Mycobacterium peregrinum were isolated from sputum samples, which were obtained from patients with different clinical aspects of mycobacteriosis, whereat were reinoculated on the universal chromogenic culture medium "UriSelect 4.

Application of chromogenic media for preliminary identification of acid-resistant bacteria.

Background: The variety of morphological and cultural characteristics of acid-resistant bacteria (ARB) makes it possible to use microscopy and estimate the growth rate and pigment formation when cultivating on solid egg media for preliminary identification only as additional indicative methods. It is necessary to develop new approaches for the cultivation and primary identification of ARB isolated from the biological material. It will allow to obtain data on the prevalence, structure, epidemiological, and clinical features of infectious processes caused by opportunistic ARB.

Evaluation of possibility of cultivation of acid resistant bacteria on solid egg-based and agar cultural media.

Background: The increase in the number of patients at risk for opportunistic infections caused by rare bacteria, which include individual representatives of acid-resistant bacteria (ARB), is a serious problem in modern health care. Significant difficulties in the etiological diagnosis of mycobacteriosis, nocardiosis, and actinomycosis are associated not only with the problem of identifying the main pathogens but also with certain difficulties in isolating pathogens from biological material.

Methods: The research provides data on 402 strains of ARB, which were isolated from various biological materials obtained from patients during examination for tuberculosis.

Reduction of amputations of frostbitten limbs by treatment using microwave rewarming.

Drug treatment of limb frostbite injuries is complicated due to the poor delivery of medications to affected tissues. External rewarming of the frostbitten area is risky and does not always result in positive outcomes because the dilatation of superficial vessels with constricted deep vessels can lead to irreversible damage, necrosis, and amputation. One of the techniques to restore perfusion of deep vessels in an affected extremity is rewarming with low-power microwave radiation in a specially designed metal chamber.

Microwave Treatment of Cold Injuries.

In spite of the fact that extremity frostbites are a widespread type of injuries in many countries, specialized equipment for frostbite treatment is lacking. Treatment is carried out by conservative methods. The best results are obtained by using thermal isolation of injured tissues and activation of internal warming.

Multilayer PZT 95/5 Antiferroelectric Film Energy Storage Devices with Giant Power Density.

A new type of energy storage devices utilizing multilayer Pb(Zr Ti ) Nb O films is studied experimentally and numerically. To release the stored energy, the multilayer ferroelectric structures are subjected to adiabatic compression perpendicular to the polarization direction. Obtained results indicate that electrical interference between layers (10-120 layers) during stress wave transit through the structures has an effect on the generated current waveforms, but no impact on the released electric charge.

Field estimation of deformation modulus of the soils by multichannel analysis of surface waves.

The paper presents the processed results of Plate Load Tests and of Multichannel Analysis of Surface Waves for dispersive and semi-rocky soils at the sites with different soil conditions located in the Perm Region, Russian Federation. Unit weight and deformation modulus were calculated from the obtained data.

The EEG Activity during Binocular Depth Perception of 2D Images.

The central brain functions underlying a stereoscopic vision were a subject of numerous studies investigating the cortical activity during binocular perception of depth. However, the stereo vision is less explored as a function promoting the cognitive processes of the brain. In this work, we investigated a cortical activity during the cognitive task consisting of binocular viewing of a false image which is observed when the eyes are refocused out of the random-dot stereogram plane (3D phenomenon).

Ultrahigh energy density harvested from domain-engineered relaxor ferroelectric single crystals under high strain rate loading.

Relaxor ferroelectric single crystals have triggered revolution in electromechanical systems due to their superior piezoelectric properties. Here the results are reported on experimental studies of energy harvested from (1-y-x)Pb(InNb)O-(y)Pb(MgNb)O-(x)PbTiO (PIN-PMN-PT) crystals under high strain rate loading. Precise control of ferroelectric properties through composition, size and crystallographic orientation of domains made it possible to identify single crystals that release up to three times more electric charge density than that produced by PbZrTiO (PZT 52/48) and PbZrTiO (PZT 95/5) ferroelectric ceramics under identical loading conditions.

Potential Role of Catecholamine Response to Acute Hypoxia in the Modification of the Effects of Radioprotectors.

Involvement of hormonal response (catecholamine release) to acute hypoxia induced by radioprotectors in modification of their radioprotective properties was studied in experiments on outbred mature female albino mice, female albino rats, and dogs of both sexes. The response intensity was evaluated by the reduction of radioprotective and toxic properties of indralin (a α1-adrenoceptor agonist and a radioprotector). The radioprotective effect of indralin was measured using lethal doses of whole-body γ-irradiation ((60)Co) and its acute toxicity was assessed by LD50.
