Assessment of the diversity of vascular plants in phytocenoses with a share of Quercus mongolica on the territory of Relic Oaks State Reserve

In this paper, we assess the diversity of vascular plants in phytocenoses with Quercus mongolica (family Fagaceae) on the territory of the Relic Oaks State Reserve (Eastern Siberia, Transbaikal region), where Q. mongolica is located at the northwestern boundary of the areal. The descriptions of phytocenoses have been processed in the PAST3 application. The similarity of species composition has been determined using the Jaccard index. The resulting tree diagram shows two groups of descriptions at a similarity level of 0.14-0.15. The first group includes the descriptions of mixed forest quadrats, in which Q. mongolica is a co-edificator. The second group of descriptions presents the communities where Q. mongolica is the only species in the tree layer. The analysis of the tree diagram shows the dependence of species richness within the phytocenoses on the surface patterns and edaphoclimatic conditions. The phytocenoses located on steep southern slopes show less diversity

Regional Aspects of Nosocomial Infection As a Medical and Social Problem

Prevention of nosocomial infection (NI) is an important medical and socioeconomic problem. And though certain organizational and practical measures are implemented in Russia every year to reduce NIs, the problem is still relevant from medical and social points of view. The risk of infection are both for patients and medical workers. In Russia, the minimum economic damage caused by NIs is 2.5–5 billion rubles annually. According to the Office of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Republic of Mordovia, the total incidence of NI in the region is at a low level. The incidence rate was 0.01 per 1000 patients in hospitals. The dynamics of the last five years demonstrates a decrease in hospital-acquired infections. In the dynamics of the last five years, incidence rates of purulent-septic infections of newborns and postpartum women, postoperative purulent-septic complications and post-injection complications had an unstable downward trend. Thus, purulent-septic infections of newborns and postpartum women and postoperative infections are dominated in the structure of nosocomial infections. Analysis of dynamics of morbidity in recent years in the Republic of Mordovia suggests that the measures taken to prevent NI are quite effective and are manifested with consistently low rates

Influence of the biologically active dietary supplement Floravit® on the skin and hair structure in sable (Martes zibellina)

It is important to search for new highly effective multicomponent compounds that are able to influence several of animals’ homeostasis systems simultaneously to improve the physiological adaptation of fur animals to different conditions of nutrition. This is the function of the feed additive Floravit® – a natural bioregulator. The compound is a combination of biologically active ingredients produced by the mycelial fungus Fusarium sambucinum. Studied was the effect of Floravit® on the structure of the skin and hair in adult female sable (Martes zibellina). The scientific and economic experiment was conducted at the JSC “Plemzavod Pushkinskyi” in the Moscow Region during the period of winter fur formation in October-November. The study of the morphological structure of the hair and skin cover was carried out in the chine, side and rump topographical areas. The structure of the guard hairs in the main topographical areas was examined on a scanning electron microscope. The experiment showed that administration of Floravit® per os to adult female sable at a dose of 1.0 ml per head per day throughout the period of winter pelt formation in October-November has an influence on the morphological structure of all the categories of hair on all topographic pelt areas. Animals in the test group exposed to Floravit® exhibited an increase in guide hair length on the chine and side, when compared to controls, by 4.1 mm (p < 0.001) and by 2.8 mm (p < 0.01), respectively. The length of guard hair on the chine, side and rump increased by 8.1, 7.8 and 7.8 mm (p < 0.001), respectively. An increase in down hair length was recorded in all areas of the pelt, when compared to controls, by 13.0, 4.5 and 6.3 mm (p < 0.001). An increase in dermal thickness was recorded in the chine area by 0.7 mm (p < 0.001). The specified changed in the skin and hair structure in sable adult females after using Floravit® have shown a positive influence on the quality of hair cover. As a result, bioregulator Floravit® takes part in the adaptation process of the sable organism to external factors

Measuring the State Sector and Assessing Its Effectiveness: Approaches and Implications

Despite the increasing role of the state sector in the economies of many countries, the criteria and approaches to comparative analysis and evaluation of the performance of state-owned enterprises are still ambiguous, as are the methods for cross-country comparisons of the scale of state presence in the economy. The purpose of the article is to systematize the main approaches to measurement of the size of the state sector using Russian economy as an example, as well as to substantiate the significance of this information in assessing the performance of companies with different forms of ownership in the investment and managerial decision-making process. The problems of the information environment, such as the fragmentation of data, incomplete publication of company reports, and the specifics of national databases in different countries, complicate and distort empirical research. Meanwhile, there are significant differences in the performance of state-owned and private companies, as well as in their investment attractiveness to investors in the financial market. International approaches to solving these problems consist in the formation of consolidated and unified databases, inclusion of stateowned companies in the system of national accounts, and creation of guidelines on uniform principles of transparency and accessibility of financial reports. Given the growing restrictions on access to information along with the trend towards the growth of the state sector in Russia, there is an increasing need to develop a unified methodology to measure its scale and assess its impact on the economy, investment and stock market. The proposed methodology and the obtained empirical results allow not only to comprehensively assess the contribution of the state sector in creating GDP and increasing the capitalization of the stock market, but also to conduct comparative studies of performance indicators and stock returns in companies with different ownership structure, as well as an international empirical analysis of the state sector impact on the economies and the financial and economic performance of companies

Extracellular vesicles derived from Acholeplasma laidlawii PG8

Extracellular vesicle production is believed to be a ubiquitous process in bacteria, but the data on such a process in Mollicutes are absent. We report the isolation of ultramicroforms - extracellular vesicles from supernatants of Acholeplasma laidlawii PG8 (ubiquitous mycoplasma; the main contaminant of cell culture). Considering sizes, morphology, and ultrastructural organization, the ultramicroforms of A. laidlawii PG8 are similar to membrane vesicles of Gram-positive and Gram-negative bacteria. We demonstrate that A. laidlawii PG8 vesicles contain genetic material and proteins, and are mutagenic to lymphocytes of human peripheral blood. We show that Mycoplasma gallisepticum S6, the other mycoplasma, also produce similar structures, which suggests that shedding of the vesicles might be the common phenomenon in Mollicutes. We found that the action of stress conditions results in the intensive formation of ultramicroforms in mycoplasmas. The role of vesicular formation in mycoplasmas remains to be studied. ©2011 with author. Published by TheScientificWorld

IR and NMR spectra, intramolecular hydrogen bonding and conformations of mercaptothiacalix[4]arene molecules and their para-tert-butyl-derivative

It is demonstrated that the introduction of p-tert-butyl groups dramatically influences the conformational behaviour of the mercaptothiacalix[4] arene molecules. Quantum-chemical computations in combination with IR and NMR spectroscopy prove that, in contrast to closely related calixarenes, the 1,3-alternate becomes a dominant conformer of p-tert-butyl-mercaptothiacalix[4] arene not only in crystal, but also in solutions and in vacuum. It is shown that the title molecules form essentially non-cooperative intramolecular hydrogen bonds: their SH groups are intramolecularly H-bonded solely to the sulfide groups bridging thiophenolic units. The enthalpy of this bonding, evaluated from Iogansen's rule, amounts to ca. 1.5 kcal mol-1 per one SH•••S bond, which about four times smaller than the enthalpies of cooperative intramolecular H-bonds formed by related calixarenes and thiacalixarenes. © 2007 Springer Science+Business Media B.V
