Carbon Allotropes-Based Paints and Their Composite Coatings for Electromagnetic Shielding Applications.

The present manuscript reports on optimized formulations of alcohol-based conductive paints for electromagnetic interference shielding (EMI), which can ensure compatibility and reduce the visibility of electronic equipment, as a continuation of our previous work in this field, which examined water-based formulations for other applications. Graphite, carbon black, graphene, FeO, Fe ore, and PEDOT:PSS in various ratios and combinations were employed in an alcohol base for developing homogeneous paint-like fluid mixtures that could be easily applied to surfaces with a paintbrush, leading to homogeneous, uniform, opaque layers, drying fast in the air at room temperature; these layers had a reasonably good electrical conductivity and, subsequently, an efficient EMI-shielding performance. Uniform, homogeneous and conductive layers with a thickness of over 1 mm without exfoliations and cracking were prepared with the developed paints, offering an attenuation of up to 50 dB of incoming GHz electromagnetic radiation.

Novel Water-Based Paints for Composite Materials Used in Electromagnetic Shielding Applications.

The development of materials offering electromagnetic interference (EMI) shielding is of significant consideration, since this can help in expanding the lifetime of devices, electromagnetic compatibility, as well as the protection of biological systems. Conductive paints used widely today in electromagnetic interference (EMI) shielding applications are often based on organic solvents that can create safety issues due to the subsequent environment problems. This paper concerned the development of eco-friendly conductive water-based paints for use in EMI-shielding applications.

[The organizational and methodological bases of medical reconnaissance in extreme situations].

The article deals with the process of medical reconnaissance organisation in various extreme situations, including local wars and armed conflicts. The authors suggest that there is a definite need in special units and mobile sanitary-epidemiological groups, trained and equipped for the task. They also recommend that these units should be formed up in the deployable medical set-ups.

[Morphologic diagnosis of various forms of thymus gland diseases in children using morphometry].

Quantitative criteria of obscure thymic pathology (OTP) are obtained by morphometric study of the thymus of 102 infants with severe infectious-inflammatory processes (IIP). OTP is characterised by depression of epithelial hyperplasia in accidental involution found in 28.4% IIP and is followed by the disturbances mainly in the cell immunity system.

[The immunomodulating properties of the erythrocytes in an experimental staphylococcal infection].

Experiments on 130 mice of different strains have revealed that washed mouse erythrocytes taken on day 7 of experimental staphylococcal infection induce the pronounced increase of humoral immune response to sheep red blood cells in syngeneic recipients, while mouse erythrocytes taken on day 14 of this infection induce immunosuppression. Erythrocytes acquire immunosuppressive properties at the period of red blood regeneration.

[Systematic study of the morphology of the immune and endocrine organs during the infectious process].

Immune and endocrine organs of 259 children and adults who had died of sepsis, local purulent-inflammatory affections were studied morphologically and morphometrically. It is established, that compensatory morphological changes in the lymphoid tissue and endocrine organs are integrated into a united system the structural basis of which are numerous inter- and intra-organ correlations. A systemic interaction between the lymphoid and endocrine organs at early age is pronounced much weaker than in the adults.

Information analysis of immune and endocrine organs. Morphological changes in the course of infection.

Morphological and morphometric studies were conducted into lymphoid and endocrine organs of 259 human adults and infants with pyoinflammatory diseases (PID) and of 300 experimental mice. Informative and correlation analyses of the data thus recorded provided evidence to the effect that in the course of an infection process adaptation and compensation responses were characterized by intensified exchange of information within the immune-endocrine system (IES). Septic courses of PID were found to be accompanied by impairment of inter-organ correlations, increase in information entropy and progressive structural disorganization of the IES.

[The phenomenon of tachyphylaxis in the pathogenesis of an experimental infectious process].

Experiments on mice have revealed that the development of experimental purulent infection is accompanied by a considerable increase in the nonspecific resistance of the animals to additional infection with unrelated bacteria (the effect of tachyphylaxis). Morphologically, this is manifested by the rapid limitation of the focus of inflammation at the site of inoculation of the superinfecting agent. The state of the phagocytic apparatus is of great importance for this phenomenon as disturbances in the macrophage activity caused by the injection of carrageenan abolish the protective effect of primary infection.

[Sepsis and local inflammatory processes in infants: mathematical approach to pathomorphological differential diagnosis].

The structure of thymus, spleen, adrenal and thyroid glands and changes in peripheral white blood cells formula were studied in 97 cases of sepsis and local inflammatory processes (LIP) in infants. A complex of differential diagnostic features of sepsis and LIP was defined. Mathematical use of the complex significantly increases the objectivity of sepsis and LIP diagnosis.

The authors have synthesized a new dye which by its histochemical properties is analogous to the imported aldehyde-fuchsin but much cheaper. The production of this dye under the trade name "Fenaf" is organized at Shostka's factory of chemicals. The dye reveals neurosecretion, thyrothrophocytes of the adenohypophysis, tissue mast cells and other structures that are stained with aldehyde-fuchsin.

[Immunosuppression in experimental staphylococcal infection and its effect on antimicrobial resistance].

Experiments on CBA and (CBA X C57BL)F1 mice have revealed that a prolonged period of antigen-nonspecific immunosuppression of humoral immunity develops in experimental staphylococcal infection; this period of suppression may be preceded by a short phase of antigen-nonspecific immunostimulation. Immunosuppression is linked with the accumulation of antigen-nonspecific T-suppressors in the spleen, these T-suppressors being capable of the manifestation of their activity both in vitro and in vivo in cases of their transplantation to semi-syngeneic recipients. Immunosuppression does not aggravate the course of staphylococcal infection and is accompanied by an increase in resistance to Pseudomonas aeruginosa superinfection, which is due to the stimulation of inflammatory reaction at the site of the injection of the superinfecting agent.

[Morphological aspects of inopportune fatty metamorphosis of the thymus].

Thymus glands from 43 early infants who died of asphyxia, birth injury and inflammatory diseases were studied morphologically. Unscheduled fatty metamorphosis (UFM) of the thymus was found in 32% of cases of inflammatory diseases. Lipid containing cells of the thymus are thymic macrophages in the state of irreversible lipoid dystrophy and death.
