The subject of the research is the peculiarities of the functioning of tourism business enterprises in the context of rural development. The purpose of the article is to analyze the resource potential, conditions of organization and foreign experience of rural green tourism enterprises, assessment of the effectiveness of tourism and agricultural activities in rural areas. The methodological basis of the article is the methods and approaches of economic, institutional and sustainable development theory. In particular, systematic and holistic approaches, methods of analysis and synthesis, structural modeling were used; monographic; abstract-logical. The results of the article. It is determined that socio-economic resources of rural green tourism enterprises are understood as labor resources, accommodation facilities, separate utility rooms, machines and equipment or devices, production and technological processes (wine, food, oil and fat, fruit and vegetable canning, etc.), certain productions and activities growing flowers, medicinal herbs, farm animals, picking fruits and berries, mushrooms, honey production, fish farming, etc.) as sightseeing sites or tourist attractions. It is established that the tendency to increase the influence of tourism and resorts on the dynamics of economic and social development of the region is maintained by increasing domestic and foreign tourist flows, as well as increasing revenues from tourism to the local budget. It is substantiated that the assessment of economic efficiency of rural green tourism enterprises should be carried out on the basis of the volume of services provided by them, the costs of their implementation and profits. Field of application of results. The obtained results can be used in the process of further scientific study of an important problem – improving the efficiency of the market of tourist services and rural green tourism enterprises. Conclusions. It is established that rural green tourism enterprises in the leading countries of the world have developed significantly, and their number is 10.0-50.0 times higher than the number of domestic ones. Thus, rural green tourism is a mass activity, employment and income of rural residents. Therefore, in European countries, it is seen as an alternative to agriculture, where the number of employees is constantly declining due to automation and digitalization, and its support has become a state program. It also provides recreation for almost 1/3 of all tourists. Therefore, it is important to implement the most effective areas of experience in rural tourism in Ukraine. This is the organization of thematic annual advertising campaigns for rural recreation with state and regional support; indirect state support in the form of non-taxation; development of pilot projects for the development of rural green tourism for individual rural areas; combining rural green tourism with gastronomic, cognitive, etc. types of tourism; strengthening the greening of rural green tourism.

Authors: Dolgov S. V. , Mikhailov R. V. , Serova T. А. , Shulga O. A. , Firsov A. Р. 
Published: May 2022

Plum pox virus (PPV), the causative agent of plum Sharka disease, is currently considered the most dangerous pathogen of apricots, plums and peaches. The transformation of plum with viral genes, such as coat protein, can provide novel virus resistant forms or gene resources for breeding new resistant varieties. For improving the plants resistance to Plum pox virus (PPV) two technologies were used. One based on co-suppression and another on RNA-silencing. Binary vector pCamPPVcp that contained the selective hpt gene and ppv-cp gene in sense-orientation (driven by double 35S promoter) was used for realization post-transcriptional gene silencing. Vector pCamPPVRNAi contained self-complementary fragments of gene ppv-cp (698bp) driven by double 35S promoter and the hpt and gus genes.The fragments of ppv-cp gene were separated by pdk-intron to produce a “hairpin” RNA structure in antisense-sense orientation. Seven independent transgenic lines with ppv-cp gene and five transgenic lines with a two inverted repeats of ppv-cp gene fragment were produced. Stable integration of genes into genome of plants was confirmed by PCR analyses. The accumulation of coat protein was evaluated by Western blot assay in five from six analyzed lines. The transgenic shoots were rooted and acclimatized to the greenhouse. After grafting by PPV infected buds in all control and ppvcp transformed plants were detected by Western blot analysis lines corresponding PPV coat protein, whereas no any spots corresponding PPV coat protein were observed in samples from plants transformed “hairpin” construct. These preliminary results confirmed the efficiency of RNAi strategy for protection plants from virus attack in general, and for stone fruits from PPV in particular.
Сучасні погляди на молекулярні та судинні механізми розвитку прееклампсії
Authors: Shumilina Tetiana , Slyvka Yaroslava 
Published: May 2022

у статті узагальнено аргументи та контраргументи в рамках наукової дискусії щодо питання механізмів розвитку прееклампсії. Основна мета цього дослідження це узагальнення інформації про молекулярні та судинні механізми прееклампсії. Завдяки детальному вивченню літературних джерел, їхній систематизації та підходів до вирішення проблеми, було виявлено, що генетичні та фактори навколишнього середовища викликають дезадаптацію плаценти, що призводить до дефектної плацентації, апоптозу інвазивних цитотрофобластів, неадекватного експансивного ремоделювання спіральних артерій та плацентарного тиску. Актуальність дослідження даної патології полягає в тому, що вона багато в чому визначає перинатальну та материнську захворюваність. Однак, на сьогодні немає чіткого уявлення про особливості молекулярних та судинних механізмів прееклампсії, тому це призводить до суперечностей у лікуванні таких вагітних жінок, що перешкоджає своєчасному, адекватному лікуванню та профілактиці. Було використано бібліосемантичний метод та контент-аналіз літератури відносно питань нових досліджень по особливостям механізмів розвитку прееклампсії. В статті представлено результати досліджень, які засвідчили, що плацентарна ішемія сприяє вивільненню біоактивних факторів у материнський кровообіг, викликаючи дисбаланс між антиангіогенною розчинною тирозинкіназою-1, розчинним ендогліном та проангіогенним судинним ендотеліальним фактором росту, фактором росту плаценти та трансформуючим фактором росту B. Плацентарна ішемія також стимулює вивільнення прозапальних цитокінів, фактору, що індукує гіпоксію, активних форм кисню та агоністичних аутоантитіл до рецепторів ангіотензину 1 типу. Ці циркулюючі фактори націлені на ендотелій судин, викликаючи генералізований ендотеліоз у системних, ниркових, церебральних та печінкових судинах і призводять до зменшення судинних розширювачів, таких як оксид азоту, простациклін, фактор гіперполяризації, та збільшення судинозвужувальних засобів, таких як ендотелін-1 та тромбоксан А2. Біоактивні фактори також впливають на гладку мускулатуру судин і посилюють механізми судинного скорочення, включаючи цитозольний Са2+, протеїнкіназу С та Rho-кіназу. Дослідження емпірично підтверджує та теоретично доводить, що подальше розуміння взаємодії між біоактивними факторами, судинними механізмами та молекулярними мішенями повинно допомогти розробити більш ефективні заходи для раннього виявлення та профілактики прееклампсії. Результати проведеного дослідження можуть бути корисними для лікарів первинної ланки, гінекологів, кардіологів, терапевтів.
