AbstractThe determination of factors that adversely affect the populations of rare plant species and development of measures to eliminate them are the important conditions for maintaining the rare component of natural flora. The article describes the study of forest phytocoenoses in the eastern territory of South-Podolsk Forest Steppe of Ukraine. The influence of natural conditions, morphological and physiological features of Sorbus torminalis (L.) Crantz on the distribution and population density in the studied region was analysed. The species is found in 80 quarters of different forestry districts with the population densities ranging from single to 300 individuals per hectare. The rare species has little prospect of natural seed restoration. The natural reforestation process of Sorbus torminalis is largely due to the specific conditions of phytocoenosis, age and vital structure of the forest stand. Most local populations have a low lifecycle. Very rare seed reproduction makes this species extremely vulnerable to the effects of any negative factors.In the oak-hornbeam plantations, the plants of reproductive age prevail, but with the die-back of old individuals, the influx of renewal has almost disappeared. According to the results of the studied region, the oak plantations with Sorbus torminalis are found to have better values of the species distribution in the protected area compared to the recreational and economic ones (Sorbus torminalis remains in any sanitary condition in the plantations and on clean felling). Artificial resettlement should be carried out in places with a small projective cover of the vegetation, and Sorbus torminalis should be introduced into Quercus robur cultures as an associate species. This territory is the northeast boundary of the natural growth of the species.

Статья посвящена изучению сопутствующей патологии, у женщин репродуктивного возраста, обращающихся в стационар с жалобами на нарушения менструального цикла (НМЦ). Актуальность данной тематики не вызывает сомнения, так как с каждым годом в России и во всем мире регистрируется все большее количество случаев НМЦ. По мнению ряда авторов, данные нарушения могут составлять до 50% всех патологий женской половой сферы. Большой интерес представляет и изучение ряда сопутствующих заболеваний, которые могут отягощать течение НМЦ или наоборот, приводить к их развитию. Целью работы стал анализ разнообразной сопутствующей патологии при НМЦ, с выявлением основных причин нарушений менструального цикла у женщин фертильного возраста. Объектами исследования стали 300 пациенток, с диагнозом НМЦ, которые были разделены на 3 группы, в зависимости от уровня лечебного учреждения, где они проходили обследование - по 100 пациенток: проходивших обследование в больнице скорой медицинской помощи, обследующиеся в женской консультации и проходящие лечение сопутствующей онкопатологии в областном онкологическом диспансере. В дальнейшем проводилась дополнительное деление в каждой группе на 2 подгруппы, в зависимости от того был ли НМЦ впервые выявленным или повторно выявленным. В самой работе проводился подробный анализ сопутствующей патологии у женщин в зависимости от группы и их возраста. Определялись не только «пораженные» системы органов, но и проводился углубленный анализ по нозологиям. Работа интересна еще и тем, что в ней у всех пациенток на протяжении исследования определялся уровень стресса и наличие возможных депрессивных состояний. Определение наиболее вероятных причин НМЦ стало завершающим этапом исследования. Полученные данные могут приблизить практикующих акушеров-гинекологов к более полному пониманию различных нарушений менструального цикла, что в целом, положительно скажется на качестве и эффективности оказываемой медицинской помощи The article is devoted to the study of concomitant pathology in women of reproductive age who go to the hospital with complaints of menstrual irregularities (NMC). The relevance of this topic is beyond doubt, since every year in Russia and around the world an increasing number of cases of NMC are registered. According to a number of authors, these violations can account for up to 50% of all pathologies of the female genital area. Of great interest is the study of a number of concomitant diseases that can aggravate the course of NMC or, conversely, lead to their development. The aim of the work was to analyze a variety of concomitant pathologies in NMC, with the identification of the main causes of menstrual irregularities in women of fertile age. The objects of the study were 300 patients diagnosed with NMC, who were divided into 3 groups, depending on the level of the medical institution where they were examined - 100 patients each: who were examined in an emergency hospital, examined in an antenatal clinic and undergoing treatment for concomitant oncopathology in the regional oncological dispensary. Subsequently, an additional division was carried out in each group into 2 subgroups, depending on whether the NMC was newly detected or re-identified. In the work itself, a detailed analysis of comorbidities in women was carried out, depending on the group and their age. Not only the "affected" organ systems were identified, but an in-depth analysis of nosologies was also carried out. The work is also interesting in that during the study the level of stress and the presence of possible depressive states were determined in all patients. Determination of the most probable causes of NMC was the final stage of the study. The data obtained can bring practicing obstetricians and gynecologists closer to a more complete understanding of various menstrual irregularities, which, in general, will have a positive effect on the quality and effectiveness of medical care

The problem of endometrial polyps in women of reproductive age is one of the urgent problems of modern gynecology. The detection rate of PE according to the data of domestic and foreign scientists reaches 25–35%, and therefore they occupy a leading place in the structure of intrauterine pathology.The aim. To study the levels of specific autoantibodies (to double-stranded DNA; to TrM‑03 antigens and collagen) and to assess their prognostic value for the risk of PE formation and recurrence in patients of reproductive age.Materials and methods. Examination of 86 patients aged 18 to 45 years (average age was 34.1 ± 6.3 years), admitted for hysteroscopy, hysteroresection of PE. Study of the relative content of specific autoantibodies to double-stranded DNA; to TrM‑03 antigens and collagen in blood serum was carried out by the method of enzyme-linked immunosorbent assay using specialized reagent kits (ELI-P-Complex).Results. In the course of this study, it was found that in the overwhelming majority of cases (65.1%) PEs were manifested by various types of AMC. All patients with PE were diagnosed with a significant decrease in the level of autoantibodies to double-stranded DNA, which is a marker of apoptosis processes, as well as a statistically significant decrease in the levels of autoantibodies to platelet antigens TrM‑03. The profile of deviations in the level of autoantibodies to TrM‑03 from the reference range in the area of negative values correlated with an increase in the average level of autoantibodies to collagen.Conclusions. Determination of the levels of auto-ATs to double-stranded DNA in serum can be used as a marker for predicting the recurrent course of PE. Determination of the levels of auto-ATs to platelet antigens TrM‑03 and to collagen in blood serum can be used as markers for the development of AMC by the type of BMC or a combination of BMC and BMC in patients with endometrial polyps.

ABSTRACT Lactobacillus sakei is a lactic acid bacterium widely represented in the natural flora of fresh meat. The aim of this study was to analyze the differences in protein expression during environmental changes encountered during technological processes in which L. sakei is involved in order to gain insight into the ability of this species to grow and survive in such environments. Using two-dimensional electrophoresis, we observed significant variation of a set of 21 proteins in cells grown at 4°C or in the presence of 4% NaCl. Six proteins could be identified by determination of their N-terminal sequences, and the corresponding gene clusters were studied. Two proteins belong to carbon metabolic pathways, and four can be clustered as general stress proteins. A phenotype was observed at low temperature for five of the six mutants constructed for these genes. The survival of four mutants during stationary phase at 4°C was affected, and surprisingly, one mutant showed enhanced survival during stationary phase at low temperatures.

Background: AUB is any abnormal uterine bleeding in the absence of any palpable pelvic pathology and demonstrable extra genital causes. AUB is responsible for 10% of gynaecological complaints. Thyroid hormone is very important to affect the menstrual pattern. The objective of this study was to evaluate thyroid function test in women with AUB and to assess the menstrual pattern in women with thyroid dysfunction.Methods: The present study was conducted in the Department of Obstetrics and Gynecology, Laxmi Narasimha Hospital, Hanamkonda, Hyderabad, Telangana, India 80 women of reproductive age group between 15-45 years women with menstrual disorders like menorrhagia, oligomenorrhea, hypomenorrhea, polymenorrhea, metrorrhagia, and amenorrhea. Quantitative determination of T3, T4, and TSH by CLIA estimated in autoanlyser.Results: About 80 women participated in the study in which Most of the subjects belong to 26-30 years of age group. Maximum patients i.e. 41 (51.2%) patients were para one to 2. Commonest cause bleeding pattern was menorrhagia 41.25%. 15 apparently normal patients with AUB belonged to the category of subclinical hypothyroidism (15%). Hormonal levels revealing profound hypothyroidism in patients without any symptoms was present in only 10% of cases. 2.5% of cases had hyperthyroidism though they were clinically normal. Patients who were sub-clinically hypothyroid were maximally presenting as polymenorrhoea (50%) and menorrhagia (12.1%) and only 6.27% of patients had oligomenorrhoea. Patients who were profound hypothyroid were predominantly having polymenorrhagia (83.3%) and (62.5%) of patients had oligomenorrhoea.Conclusions: So, biochemical evaluation of thyroid functioning should be made mandatory in all provisionally diagnosed cases of AUB to detect thyroid dysfunction.

Russian Forest

Research of the flora of some areas of the Central Russian forest-steppe shows that a number of plants has deviations from the main species characteristics. The fact that there is a continuous series of variations from individual to species level in nature has long been known for a long time (Darwin, 1991). The reasons and results of this are very different and unpredictable. The ability of plants to change their phenotype is genetically determined. The scope of intraspecific differentiation depends on many external causes. The intraspecific potential of plants reveals itself when ecological situation and geographical fragmentation modify. In result, populations which significantly differ from the main genotype are formed. The impact of new environmental conditions is shown in the examples of Genista tinctoria L., Achillea millefolium L., Salvia pratensis L. The Trifolium lupinaster or Lupinaster pentaphyllus is an example of the introduction of geographically distant genetically stable races. Some species can be represented by different morphobiotypes. For example, erect (haying) and lying (pasture) forms of Lotus corniculatus, Medicago falcata, Astragalus onobrychis. There are some transitional forms. Populations of tall and low growing Anemone sylvestris were observed. A pronounced manifestation of intraspecific diversity is the polychrome of flowers. It was found in рlants from different families: species of iris, Schrenka tulip (Tulipa suaveolens), lily of the Saranka (Lilium pilosiusculum) and others. The collection of the botanical garden for over 20 years contains garden forms of plants of natural flora, which appeared due to spontaneous new formations. These are variegated forms of Aegopodium podagraria and Galeobdolon luteum. The results of the introduction of species and intraspecific diversity of rare and economically valuable plants in the Botanical garden of the Voronezh state University are presented.

The research was conducted on the structure and characteristics of the growth of shoots of the genus Viburnum L. There are significant differences in the structure and dynamics of growth within the genus, so the determination of the structural features of the shoots of species of the genus Viburnum is relevant. The research of the dynamics of shoot growth was carried out according to the method of A.A. Molchanov and V.V. Smirnov (1967). The species studied by us belong to three sections of the genus Viburnum; the peculiarities of buds structure generally determine the structure of the shoots in the species of each section. It was found that the type of each of the three sections of the genus is characterized by a special structure of the shoots. It has been studied the rhythm of growth and development of native and introduced species of the genus Viburnum L. The terms of shoots growth of the species of the genus were analyzed, and the length of the annual growth of shoots was determined. Phenological date of the beginning and end of shoot growth was established. It was revealed that the onset of individual phenophases quite clearly correlates with the sum of effective temperatures above 5 ° C. The species of the genus Viburnum are characterized by the following types of shoots: tillering, stem, generative. Intensive growth of shoots of all studied species occurs in May - mid-June. In the species of the section Lantana, there are 2 peaks of shoot growth - May and mid-July. According to the duration of growth of shoots, viburnum can be divided into two groups: 1) with a short period of growth (65 - 75 days): V.opulus L., V.sargentii Koehne, V.prunifolium L., V.rufidulum Raf., V.lentago L; 2) with a long period of growth (100 or more days): V.lantana L., V.carlesii Hemsl., V.veitchii C.H. Wright, V.rhytidophyllum Hemsl., V.buddleifolium C.H. Wright, V.burejaeticum Rgl. et Herd. The data obtained demonstrated that the greatest annual growth of all Viburnum species was recorded at the age of 4-7 years. A decrease in the annual growth of axial shoots states the need for works on preliminary rejuvenation of the bush.

Abstract The purpose of the study is to establish the regularities of the growth of pedunculate Oak in protective forest stands on erosion-prone slopes in the conditions of the steppe and forest-steppe of the Volga Upland. Studies have established a regular decrease in the height of the petiolate oak on the southern chernozem and gray forest soil by 6.9-11.3% with an increase in the slope of the slope by 2 times, which is associated with a drop in soil fertility as a result of increased erosion. The index of oak growth intensity with an increase in the slope slope increases on both types of soils by 21.4-38.5%, and the productivity of cambium decreases by 14.1-23.6%. The same trends in the dynamics of taxation indicators are characteristic of the accompanying species of petiolate oak-holly maple and small-leaved linden. The coefficients of determination of the relationship of growth in the height of the pedunculate oak from the indicator of growth intensity and productivity of cambium are 0.95-0.98, which indicates a close interdependence.
