The course of experimental staphylococcus infection in albino mice during action of certain factors of space flight
A study was made of the effect of certain factors of space flight, acceleration and hypokinesia, on the course of experimental staphylococcus infection in mice. Combined action of hypokinesia and acceleration caused a marked depression of the phagocytic activity of leukocytes and formation of a considerable amount of alpha toxin
Clinical Experience of Luminescent Diagnostics of Precancerous Diseases and Cervical Cancer
The article summarizes the experience of using luminescent diagnostics with the use of ytterbium porphyrin complexes in gynecology and oncology. A pharmaceutical composition based on the Yb complex of 2,4-dimethoxyhematoporphyrin IX was used as the luminescent markers within the infrared range. The determination of luminescence characteristics (luminescence intensity) was carried out using a laserfiber fluorimeter in the range of 900-1100 nm. A new method for diagnosis of cervical disease has been proposed. The method of luminescent diagnostics allows to conduct a survey of a large number of patients in a short time. The method of luminescent diagnostics using the ytterbium complexes of porphyrins is not invasive. The method can be used as a screening. Differences between normal and pathologically altered cervical tissue have been identified and differences between pathological changes in the cervix HSIL (CIN II, CIN III) and cervical cancer are reliable.
Keywords: Cervical cancer, squamous cell carcinoma, diagnosis of cervical cancer, squamous intraepithelial lesions of high grade β HSIL, luminescent diagnostics, luminescing in the near infrared (NIR) spectral region, porphyrins, ytterbium complexes of porphyrins
Boundary Changes of Natural Plague Foci in the North-Western Pre-Caspian
Objective of the study is to specify present-day locations and sizes of natural plague foci in the North-Western Pre-Caspian.Materials and methods. Based on the results of field and office mapping of Pre-Caspian sandy and North-Western steppe plague foci,Β conducted in 2013β2014, designed have been electronic maps of the sectors, situated in the periphery of the foci.Results and conclusions.Β Detected has been marked reduction in sizes of natural foci owing to plowing of arid pastures. Over a significant distance, newΒ natural focal boundaries are represented by linear elements of hydrography. Wherein such elements are absent, sector frames, in whichΒ evidence of enzooty remains, are accepted as formalized external boundaries. The process of deep and irreversible anthropogenicΒ transformation of landscapes has resulted in the reduction of enzootic as regards plague territories: the steppe focus area has decreasedΒ by 22 %, being 51152 sq. km, the sandy one β by 13 %, amounting to 62510 sq. km. Farming on the extensive territories as a meansΒ of radical alterations of the landscapes has made the lands unsuitable for habitation of the little souslik, midday and tamarisk gerbils,Β which is an evidence of a complete loss of plague enzooty factors in the territory. The survey of actual position and sizes of naturalΒ plague foci within the rigid bonds, plotted on topographic maps and easily identifiable afield, provides for substantiated planning andΒ complex prophylactic plague-control measures. Novel spatial parameters of the natural foci are suggested for the inclusion into officialΒ regulatory-methodological documents, guiding performance of epidemiological surveillance over plague
Single and molecular ion irradiation-induced effects in GaN : experiment and cumulative MD simulations
An investigation of mechanisms of enhancement of irradiation-induced damage formation in GaN under molecular in comparison to monatomic ion bombardment is presented. Ion-implantation-induced effects in wurtzite GaN bombarded with 0.6 keV amu(-1) F, P, PF2, PF4, and Ag ions at room temperature are studied experimentally and by cumulative MD simulation in the correct irradiation conditions. In the low dose regime, damage formation is correlated with a reduction in photoluminescence decay time, whereas in the high dose regime, it is associated with the thickness of the amorphous/disordered layer formed at the sample surface. In all the cases studied, a shift to molecular ion irradiation from bombardment by its monatomic constituents enhances the damage accumulation rate. Implantation of a heavy Ag ion, having approximately the same mass as the PF4 molecule, is less effective in surface damage formation, but leads to noticeably higher damage accumulation in the bulk. The cumulative MD simulations do not reveal any significant difference in the total amount of both point defects and small defect clusters produced by light monatomic and molecular ions. On the other hand, increased production of large defect clusters by molecular PF4 ions is clearly seen in the vicinity of the surface. Ag ions produce almost the same number of small, but more large defect clusters compared to the others. These findings show that the higher probability of formation of large defect clusters is important mechanism of the enhancement of stable damage formation in GaN under molecular, as well as under heavy monatomic ion irradiation.Peer reviewe
Luminescence in anion-deficient hafnia nanotubes
Hafnia-based nanostructures and other high-k dielectrics are promising
wide-gap materials for developing new opto- and nanoelectronics devices. They
possess a unique combination of physical and chemical properties such as
insensitivity to electrical and optical degradation, radiation damage
stability, a high specific surface area, and an increased concentration of the
appropriate active electron-hole centers. The present paper aims to investigate
the structural, optical, and luminescent properties of anodized
non-stoichiometric nanotubes. As-grown amorphous hafnia nanotubes and
nanotubes annealed at 700{\deg}C with a monoclinic crystal lattice served as
samples. It has been shown that the bandgap for direct allowed
transitions amounts to eV for amorphous and eV for
monoclinic nanotubes. For the first time, we have studied the features of the
intrinsic cathodoluminescence and photoluminescence of the obtained nanotubular
structures with an atomic deficiency in the anion sublattice at
temperatures of 10 and 300 K. A broad emission band with a maximum of 2.3-2.4
eV has been revealed. We have also conducted an analysis of the kinetic
dependencies of the observed photoluminescence for synthesized samples
in the millisecond range at room temperature. It showed that there are several
types of optically active capture and emission centers based on vacancy states
in the and positions with different coordination numbers and
a varied number of localized charge carriers (, , and ). The
uncovered regularities can be used to optimize the functional characteristics
of developed-surface luminescent media based on nanotubular and nanoporous
modifications of hafnia.Comment: 15 pages, 6 figures, 3 tables, 50 reference
Increasing the efficiency of investments on survey of abundant land for their return to agricultural us
The "βState program for the effective involvement of abundant agricultural land in the use and the development of the reclamation complex of the Russian Federationβ for 2021β2030" assumes the return of 12 million hectares out of 44 million hectares of all abandoned agricultural land (AAL) in the Russian Federation. The costs of 12 million hectares survey can be considered productive, while the costs of surveying the remaining 32 million hectares should be considered unproductive. The application of the new geoinformation database of βSoils of agricultural lands of the Russian Federationβ (DB SALRU) developed by the Federal Research Centre βV.VΒ Dokuchaev Soil Sience Instituteβ allows reduction of unproductive costs. By the example of the Vladimir region, a typical Russian region with AAL, the option of ranking AAL by their quality was demonstrated to determine the order of their return to agricultural use. The soil quality criteria are the bonitet and the normative yield of grain crops, which are part of the DB SALRU. It is proposed to consider the expenditures on the survey of AAL for the soils, which are first to be returned to agricultural use, as productive costs. These soils occupy 25% of the AAL of the region. The best quality soils are characterized by more than 40 points of bonitet and the standard yield of grain crops of more than 20 centners/ha. The cost of surveying the lands of the first order of returning to agricultural use is 10 million 80 thousand rubles. Survey of AAL soils of IIβIV orders of involvement in agricultural use, with relatively poor quality compared to the soils of the first order, is proposed to be conducted in the case of expansion of the State program in the future. This would save the unproductive expenses for the survey of AAL for the Vladimir region by 30 million 165.5 thousand rubles. The application of the proposed GIS-approach makes it possible to reduce unproductive expenses for the survey of AAL in the Russian Federation nearly by 5.600 million rubles

The increasing impact of anthropogenic factors and climate change affect the growth of a number of taxa of hybrid nature. These taxa are widespread among various taxonomic groups of aquatic and semi-aquatic plants. The genus Sparganium L. Π is not an exception. In that regard, the aim of this study is to conduct biomorphological investigation of Sparganium Γ longifolium Turcz. ex Ledeb., evaluate qualitative and quantitative criteria for the hybrid similarities and differences with its parental species, as well as to analyze data on its habitat characteristics. Samples were collected in 2014β2016 from waterbodies in European Russia (Tver and Yaroslavl oblasts). In the study on biomorphology of S. Γ longifolium we used live and fixed materials, as well as herbarium funds of IBIW, MXA and MW. To establish and specify taxonomic features of the hybrid under study, indicating to its similarity with a certain ancestral species, our data on the morphology and ecology of S. emersum Rehm. and S. gramineum Georgi. are used. During field studies, the type of water object where the hybrid was detected, ecological characteristics of its habitat (type of soil, depth, water temperature and pH) are determined; the list of taxa which enter into the cenosis composition is compiled. The biomorphological investigation of S. Γ longifolium shows that by life form this hybrid, as well as its parental species, is a vegetative-mobile evidently-polycentric annual or biennial plant of vegetative origin with a racemose root system. The following should be attributed to the characteristic features justifying the hybrid origin of S. Γ longifolium: 1) a wider, slightly carinated lamina (as in S. emersum); 2) a branched inflorescence (as in S. gramineum); 3) the lower covering leaf of inflorescence, often exceeding the total length of the latter; 4) fruits with a straight (as in S. emersum) as well as bent (as in S. gramineum) style. Interestingly, some populations of S. Γ longifolium are rich in terate forms that can be explained by back crossing with one of the parental species or pleiotropic mutation(s). It is established that S. Γ longifolium is not widespread in European Russia, is a typically freshwater species, occurring in the littoral zone of mesotrophic and dystrophic waterbodies (usually in lakes of glacier origin). At present, its appearance in lake ecosystems is due to accelerated eutrophication caused by increasing human activities. Perhaps earlier this hybrid formation occurred in peripheral zones of the range of S. gramineum under cyclic climate changes. Observations suggest that S. Γ longifolium exceeds S. gramineum in ecological potential. At the same time, habitat features of the latter have an effect on the hybridβs distribution potential (limitation of habitat spectrum), which is hardly exceeds S. emersum in its ecological and coenotic characteristics. 154

MODERN TREATMENT MINIMALLY INVASIVE TECHNOLOGIES RENOVASCULAR HYPERTENSION
The purpose of the research was the study of the effectiveness of balloon angioplasty and stenting of renal arteries to improve the microcirculation of the kidneys in patients with renovascular hypertension. During the period from 2010 to 2012 inclusive in the vascular compartment BSMU clinic were examined and treated 32 patients with renal artery stenosis. Inclusion criteria were: presence of verified violations of regional circulation in the kidney, the presence of symptomatic renovascular hypertension. Measures the average systolic and diastolic blood pressure mast. Patients received antihypertensive treatment to endovascular treatment. Treatment with antihypertensive medication was effective only in 9.8 % of cases. Diagnostic angiography of the renal arteries was performed using angiographic complex INNOVA 3131 IQ. After analyzing the data, the question of stenting or balloon angioplasty. After a detailed survey of 32 patients underwent endovascular intervention for renal artery 6 balloon angioplasty and stenting 26. Following the procedure, the hypotensive effect was observed in all cases. Evaluation of the results showed a significant reduction in the maximum rise in systolic blood pressure by 28 %, diastolic - 21 %. After endovascular intervention, the mean systolic blood pressure decreased by 10%, the average diastolic blood pressure - 15 %. Mean arterial pressure decreased by 8 %.
