80 pregnant women were examined after assisted reproductive technology (ART) programs: 40 women with manifestations of intrahepatic cholestasis of pregnant women (IHP) - the main group and 40 women without manifestations of IHP (comparison group).In the majority (62.5%) of patients after ART, the diagnosis of IHP established after 30 weeks of pregnancy. Some patients (27.5%) reported short-term episodes of IHP up to 24 weeks of gestation. In 17.5% of women, IHP had a severe course. Almost a third (27.5%) of women are over 35 years old. Women with IHP have a significantly higher frequency of allergies in the anamnesis (35.0%), liver pathology (20.0%) and diseases of the gastrointestinal tract (25.0%). In one third of women, IHP developed repeatedly, 42.5% of the main patients indicated a family history burdened with IHP. Almost a third of women (27.5% vs. 12.5%, p

Intrahepatic cholestasis of pregnancy (idiopathic jaundice of pregnancy, recurrent familial jaundice of pregnancy) is a benign familial disease manifesting itself in the gestational period in itching and (or) jaundice. As a rule, the disease is observed in the 3rd trimester of pregnancy, that is in the 28th-30th week, and may disappear by itself a few days after labor and recur during future pregnancies.The aim of this research is to study the role and factors of vascular homeostasis regulation in women with infertility treated with assisted reproductive technologies (ART) and with concomitant intrahepatic cholestasis. Intrahepatic cholestasis is characterized by the damage of endothelial cells of hepatic sinusoids, changes in the intrahepatic hemodynamics, increased production of cytokines and free radicals. The processes of angiogenesis in the liver are also closely connected with the functional capacity of endothelium. The L-arginine level in blood was measured using the photometric method based. The homocysteine level was measured by the enzymatic cycling method. To measure the level of placental growth factor (PGF) in blood plasma samples, we used the immunochemical method.The research has found especially severe complications in the course of pregnancy after ART in those women with intrahepatic cholestasis whose placentas developed under the conditions of endothelial dysfunction from the very beginning of pregnancy.So, these factors may be early prognostic markers of severe obstetrical and perinatal disorders in women with induced pregnancy and hepatobiliary disorders.

The occurrence of postoperative cognitive dysfunction is a negative consequence of vascular endothelial dysfunction in patients with grade I-II obesity with appropriate metabolic shifts and comorbid background, which increases the duration of treatment and worsens the prognosis in patients with acute surgical pathology. It is important to add endothelioprotectors to the intensive care unit. L-arginine hydrochloride has been shown to be pathogenetically justified as a prophylaxis for an increase in the level of antigens to von Willebrand factor in the blood of obese patients with acute surgical pathology. Administration of this substance before and during surgery is likely to improve mental performance in the postoperative period in patients with elevated body mass index, who underwent emergency cholecystectomy.

Sarcopenia is an important factor in the occurrence of complications in elderly patients with urgent surgical pathology. Decreased muscle strength and function is an important criterion for impaired early activation of such patients, which increases the number of complications and length of stay in the clinic. Identification of functional disorders of muscle tissue, as well as other metabolic disorders, such as type 2 diabetes, disorders of lipid metabolism, is important for the appointment of an adequate complex of intensive care. Prescribing levocarnitine and D-fructose-1,6-diphosphate sodium salt of hydrate is an important part of the treatment program in such patients.

The article presents a strategy for renovation in the riverside area: improvement of water protection functions; rehabilitation of disturbed territories; the use of recreational and urban planning potential of such territories for creating a recreational framework on the waterfront; integration of eco-clusters into the structure of riverside territories and the development of an integrated management system for waterfront zones. As a result of the research, the necessity of rethink the attitude to urban planning within the riverside areas is formulated. Possibilities of sustainable development of riparian territories are determined. Stages of rehabilitation of communal warehousing and industrial territories for sustainable development and rehabilitation of urban areas are proposed. A formalized model of structural renovation of the exploring areas are being built, on the basis of which the identified principles of rehabilitation are being tested. The significance of the obtained results for urban science lies in the development of new approaches to the identification and formation of the structure of territories in the area of interaction with the water area. In the formulation of the basic principles underlying the structural and planning transformations of riparian areas.

There are a number of recognition problems in different fields that can be solved with the system of pattern recognition with learning – SPRL elaborated by us. The problem of forecasting natural disasters (floods, mudslides) in the given year, the fixed region, and the period belongs to it. To solve it, it is set in the terms of pattern recognition with learning according to which it is necessary to pre-determine the learning descriptions in the same region of the previous years using data of the previous 12 months of the period. From learning descriptions, firstly are separated control descriptions, then the variants of learning and learning recognizable descriptions. Besides, it is necessary to determine descriptions in year, in the same region using data of the same previous period of the (the first model). After transformation and increasing the informativity of the learning descriptions, the knowledge and data bases are determined for learning recognizable and control descriptions in relation to the variants and classes (the second model). Using them, one decision is made on belonging to the respective class for learning recognizable descriptions, but for control descriptions – the primary decisions according to the number of variants, and then on their basis – one decision. Exactly according to the results of the recognition of control descriptions a decision is made on the occurrence (non-occurrence) of a natural disaster in the same region and period (the third model). The article discusses the arguments related to this fact. This model considers the correction of data bases with respect to variants and classes, also, defines the effectiveness of working of the SPRL and its detector of trust. Considering the specifics of forecasting, the initial data of at least 5 years are required to select the best knowledge and data bases with the use of which a disaster should be forecasted.

Oil and gas deposits differ depending on the bed size, geological-physical development conditions, oil quality and geographic location. Including them in the development is connected with various investments to the main constructions; subsistence and current material expenses also differ. Therefore, from the point of view of economic efficiency, oil and gas deposits are not equal. Location of oil and industry leads to the problem of the sequence of putting of various deposits into operation and their development rate. The sizes of oil and gas beds and available oil and gas reserves in them give reason to say which of these beds will be put into operation in the near future. Completion and development of large scale deposits require less investments compared to small scale deposits. Such deposits are usually highly productive, expenses per a production unit in them is small. All these determined importance of the use of reserves in large scale deposits in the first turn.
