The taxonomic changes in the species composition of Felidae from the beginning of classification by Carl Linnaeus to the present are considered. As is true for the whole class of mammals, the species composition of this family has undergone significant expansion. This happened due to the study of the most remote corners of our planet, and through a rethinking of the species concept. The process of rethinking is still ongoing and a further change in views on the species composition of cats is quite expected. Researchers pay special attention to the genera Leopardus and Felis, within which the validity of species statuses has been confirmed or revoked recently or in the past. An overview of the main criteria for distinguishing species and features of the application of these criteria are given. The problem of species discrimination is as important as the problem of species existence. Anthropogenic pressure leads to a decrease and deterioration of the quality of habitats. Almost all felids lead a solitary lifestyle and have low population density, sometimes occupying fragmented areas. In particular, this facilitates hybridization between some species, which also contributes to the "blurring" of both the species characteristics and the boundaries between separate species.

A New Species

The history of the genus Eupithecia Curtis is reviewed, and a preliminary redescription of the genus is proposed on the basis of the Palaearctic, Nearctic and Oriental fauna. Several Asian species previously placed in Eupithecia  have been found to be anomalous. These are examined and some are placed in related genera, two of them new (Pareupithecia and Girida). A further group (the ‘subrubescens’ group) is retained within Eupithecia as a separate species group. The genus Eva Vojnits is redescribed. A new species is described in the genus Mesoptila Meyrick. Descriptions are given of all genera involved, and full lists of taxa included within them, with the exception of Eupithecia itself. Selected adults and genitalia are illustrated. Taxonomic changes proposed in this paper include: new genera Pareupithecia, Girida; new species  Mesoptila murcida; new synonymies, Emmesocoma Warren, 1907 of Mesoptila Meyrick, 1891 and Horisme sternecki Prout, 1938 of Chloroclystis chingana Wehrli, 1926; new combinations Mesoptila melanolopha Swinhoe, 1895, Mesoptila unitaeniata Warren, 1906, Mesoptila deviridata Warren, 1907, Mesoptila excita Prout, 1958, Mesoptila festiva Prout, 1916, Eupithecia eurytera Prout, 1938, Eupithecia chingana Wehrli, 1926, Pareupithecia spadix Inoue, 1955, Girida rigida Swinhoe, 1892, Girida sporadica Prout, 1932; reinstated taxon Eupithecia brevifasciaria Leech, 1897; and status change  Girida sporadica Prout, 1932.

Systematic Structure

The article provides a systematic analysis of the species composition of plants of the flora of v. Amangeldy, Almaty region. The comprehensive study of regional floras is becoming increasingly important in connection with the implementation of the solution to the problem of studying and preserving biological diversity. Complete information about the composition of the flora of a territory is of great theoretical importance, it allows establishing the structure and Genesis of its components, to identify individual characteristics, to restore the history of formation and trends. This ultimately is the basis of rational use of plant resources and protection of rare and endangered plants, as well as to solve many important economic problems - identifying new sources and resources of medicinal, food, fodder, ornamental and other plants. One of the main characteristics of any flora is its systematic structure, namely the ratio of families, genera and species, on the one hand, and the quantitative indicators of these taxa that determine its wealth, on the other. These indicators are components of a systematic analysis of flora in general and coenoflora in particular, the data obtained using such analysis are important material for comparative floristry. From this point of view, the systematic structure of the flora acquires the significance of one of the essential indicators that characterize the flora in the regional plan. The study of the species composition of the flora is of great importance both for understanding the history of flora and landscapes of the region as a whole, and for finding ways to conserve and use biodiversity under conditions of increasing anthropogenic pressure. Research was carried out by route-reconnaissance method in combination with a detailed study of experimental sites. In the study area – V. Amangeldy was first identified: 112 species from 88 genera and 29 families, with the dominance of the families Asteraceae (24 species or 21.4 %, 17 genera), Rosaceae (15 species or 13.39%, 11 genera), Brassicaceae (11 species, or 9.82 %, 9 genera) from Dicotyledons, and Poaceae (11 genera, 12 species, or 10.71 %) from Monocotyledonous plants. The dominant families account for 62 species, which is 55.36 % of the total number of plant species growing in this territory. Leading genera Artemisia, Potentilla and Rumex. On the territory of the study, 33 forage plant species were identified: Bromus inermis (Leyss.) Holub., Rumex confertus Willd., Trifolium pratense L., Poa bulbosa L., etc. In connection with the degradation of the vegetation cover number of weed plants was 75 species, among which are: Rumex crispus L., Capsella bursa-pastoris (L.) Medik., Cannabis ruderalis Janisch., Lathyrus tuberosus L. and other. Endemic and rare species were not found. The results of the research will serve as a basis for the rational use of the flora of Amangeldy village in Almaty region, as well as for the conservation of biodiversity. Obtained as a result of a systematic analysis of the flora of Amangeldy, it will help to identify the centers of endemism and relict, as well as to solve the issues of the place and role of this flora in a number of other adjacent floras.

Abstract Drinking water, as one of the main components of the habitat, determines human health and quality of life. In the past few decades, almost all water sources, both surface and underground, have been subject to intensive anthropogenic and technogenic impact. Lake Gusinoye, which is the main source of drinking water supply to adjacent settlements, is experiencing significant anthropogenic pressure. Based on the results of hydrochemical studies, the toxic effect of heavy metals on the population health, resulting from the consumption of drinking water of the centralised water supply from Gusinoye Lake, was considered. The results of a quantitative assessment of public health hazards showed that the risk of non-carcinogenic (toxic) effects is high in the territory of the Gusinoozersk industrial hub.

Pulmonary tuberculosis is considered among the most common air-borne respiratory disease. TB is found almost all over the globe but it is also curable and preventable. However, it frequently has several negative consequences on the lung, which affects the patient's exercise tolerance capacity, everyday activities, and, ultimately, quality of life. The PTB is frequently associated with various subsequent problems. Few of which are presented in this case, along with their management. The current case involves a 36-year-old girl who had a history of pulmonary tuberculosis and was re-diagnosed with it, albeit with difficulties. She initially suffered pleural effusion, for which therapeutic tapping was performed, but it later progressed to empyema thoracis. She underwent thoracocentesis, which involved draining the fluid and breaking the fibrous septations, followed by the insertion of ICD drainage. Medical management was successful, but to return the patient to her normal daily routine activities without any signs of dyspnea or fatigue, a comprehensive rehabilitation program incorporating various respiratory techniques was devised, which proved to be an effective protocol in improving the patient's respiratory condition.

AbstractCataract surgery is the most frequently performed ophthalmic surgery worldwide. This year approximately 32 million surgeries will be performed. The journey to modern, quick, and safe cataract surgery has been quite long. This review covers topics from ancient couching to the most modern phacoemulsification and femtosecond laser-assisted cataract surgery. The gain in quality of life is the largest with cataract surgery compared to other implant surgeries (e.g. knee, hip replacement, etc.). Ophthalmology has made huge advancements in recent decades. New microsurgical tools and diagnostic equipment have been developed, together with new surgical methods and foldable intraocular lenses, made from biocompatible material. From monofocal lenses, through aspheric, toric, and multifocal lenses, to multifocal toric lenses, today almost all kinds of refractive error can be compensated, including presbyopia. Teamwork, precise preoperative assessment, and fine surgical technique should also be emphasized in order to achieve the best and most predictable postoperative results for both patient and surgeon.

At present, studies on the history of Indians in colonial Malaya have been described as one-dimensional, with the discussion mainly focusing on their arrival as immigrant groups and their involvement in the plantation sector. Other aspects of Indian history in colonial Malaya were not given proper emphasis, especially on matters considered taboo, such as those arising from toddy consumption. Even though it was acknowledged as a form of social ill, its history is rarely discussed. The introduction and supply of toddy in almost all estates at the time led to consequences that affected the quality of life of the estate labour community. This study, realising the situation, draws attention to the history of the development of toddy drinking and its effects among the Indian estate labourers in Malaya from 1900 to 1957. This study also highlights the reactions that existed on the issue of toddy and British action. In summary, this study seeks to prove that the over indulgence of toddy among Indian labourers developed at a rapid pace in Malaya, and not in India. The key information behind this situation is the growth of toddy shops in every plantation with Indian settlers, as well as British interests that wished to maintain a profitable industry, such as toddy.

The Thomas More Society of Buenos Aires begins or ends almost all its events by reciting in both English and Spanish a prayer written by More in the margins of his Book of Hours probably while he was a prisoner in the Tower of London. After a short history of what is called Thomas More’s Prayer Book, the author studies the prayer as a poem written in the form of a psalm according to the structure of Hebrew poetry, and looks at the poem’s content as a psalm of lament.

Anthropogenic Pressure

Cenotic diversity and leading ecological factors of its floristic differentiation were studied on an example of two areas – Kyiv parks "Nivki" and "Teremki". It is shown that in megalopolis the Galeobdoloni-Carpinetum impatientosum parviflorae subassociation is formed under anthropogenic pressure on the typical ecotope of near-Dnieper hornbeam oak forests on fresh gray-forest soils. The degree of anthropogenic transformation of cenofloras can be estimated by the number of species of Robinietea and Galio-Urticetea classes, as well as neophytes and cultivars. Phytoindication for hemeroby index may be also used in calculation. We propose the modified index of biotic dispersion (normalized by alpha-diversity) for the estimation of ecophytocenotic range (beta-diversity) of releves series. We found that alpha-diversity initially increases (due to the invasion of antropophytes) at low level of antropogenic pressure, then it decreases (due to the loss of aboriginal species) secondarily with increasing of human impact. Also we found that beta-diversity (differential diversity) decreases, increasing homogeneity of plant cover, under the influence of anthropogenic factor. Vegetation classification was completed by a new original method of cluster analysis, designated as DRSA («distance-ranked sorting assembling»). The classification quality is suggested to be validated on the "seriation" diagram, which is а distance matrix between objects with gradient filling. Dark diagonal blocks confirm clusters’ density (intracluster compactness), uncolored off-diagonal blocks are evidence in favor of clusters’ isolation (intercluster distinctness). In addition, distinction of clusters (syntaxa) in ordination area suggests their independence. For phytoindication we propose to include only species with more than 10% constancy. Furthermore, for the description of syntaxonomic amplitude we suggest to use 25%-75% interquartile scope instead of mean and standard deviation. It is shown that comparative analysis of syntaxa for each ecofactor is convenient to carry out by using violin (bulb) plots. A new approach to the phytoindication of syntaxa, designated as R-phytoindication, was proposed for our study. In this case, the ecofactor values, calculated for individual releves, are not taken into account, however, the composition of cenoflora with species constancies is used that helps us to minimize for phytoindication the influence of non-typical species. We suggested a syntaxon’s amplitude to be described by more robust statistics: for the optimum of amplitude (central tendency) – by a median (instead of arithmetic mean), and for the range of tolerance – by an interquartile scope (instead of standard deviation). We assesses amplitudes of syntaxa by phytoindication method for moisture (Hd), acidity (Rc), soil nitrogen content (Nt), wetting variability (vHd), light regime (Lc), salt regime (Sl). We revealed no significant differences on these ecofactors among ecotopes of our syntaxa, that proved the variant syntaxonomic rank for all syntaxa. We found that the core of species composition of our phytocenoses consists of plants with moderate requirements for moisture, soil nitrogen, light and salt regime. We prove that the leading factor of syntaxonomic differentiation is hidden anthropogenic, which is not subject to direct measurement. But we detect that hidden factor of "human pressure" was correlated with phytoindication parameters (variables) that can be measured "directly" by species composition of plant communities. The most correlated factors were ecofactors of soil nitrogen, wetting variability, light regime and hemeroby. The last one is the most indicative empirically for the assessment of "human impact". We establish that there is a concept of «hemeroby of phytocenosis» (tolerance to human impact), which can be calculated approximately as the mean or the median of hemeroby scores of individual species which are present in it.

After a short overview of the history of probiotics, the author presents the development of human intestinal microflora based on the newest genetic data and the microbiological features of main probiotics. The indications of probiotic administration have been defined and extended in recent years. The author reviews significant results of probiotic treatment in some gastrointestinal diseases based on meta-analytical data. Probiotics are useful in preventing and treating diarrhoea caused by antibiotics and Clostridium difficile caused diarrhoea. In the treatment of Helicobacter pylori infection, preparations containing certain Lactobacillus,Bifidobacterium strains or Saccaromyces boulardii could enhance by 5–10% the rate of successful eradication and reduce the incidence and severity of the side effects. Some symptoms of irritable bowel syndrome and thus the quality of life can be improved by probiotics. Their beneficial effect in ulcerative colitis was proven, while in Crohn’s disease has not yet been defined. The use of probiotics is not included in guidelines, with the exception of the Maastricht IV/Florence consensus. For each disease it is advisable to use probiotics containing strains only with proven beneficial effect. The efficiency of preparations containing mixed strains has not yet been properly investigated. The author reviews the rare but potentially serious side effects of probiotics. In Hungary, there are many probiotic preparations available which can be purchased in pharmacies without prescription: their use is more empirical than evidence-based. The European Food Safety Authority has recently rejected claims for probiotics to be classed as medicines given the lack of convincing evidence on the effects of probiotics on human health and well-being. Clearly, further research is needed to collect evidence which could be incorporated into the international guidelines. Orv. Hetil., 2013, 154, 294–304.

The interdisciplinary field of person-environment relations has, from its origins, addressed the transactional relationship between human behavior and the built environment. This body of knowledge has been based upon qualitative and quantitative assessment of phenomena in the “real world.” This knowledge base has been instrumental in advancing the quality of real, physical environments globally at various scales of inquiry and with myriad user/client constituencies. By contrast, scant attention has been devoted to using simulation as a means to examine and represent person-environment transactions and how what is learned can be applied. The present discussion posits that press-competency theory, with related aspects drawn from functionalist-evolutionary theory, can together function to help us learn of how the medium of film can yield further insights to person-environment (P-E) transactions in the real world. Sampling, combined with extemporary behavior setting analysis, provide the basis for this analysis of healthcare settings as expressed throughout the history of cinema. This method can be of significant aid in examining P-E transactions across diverse historical periods, building types and places, healthcare and otherwise, otherwise logistically, geographically, or temporally unattainable in real time and space.
