Authors: Abdullah Nada A.Z. , Jaboory Noor T.
Published: February 2022

Keywords provide the reader with a summary of the contents of the document and play a significant role in information retrieval systems, especially in search engine optimization and bibliographic databases. Furthermore keywords help to classify the document into the related topic. Keywords extraction included manual extracting depends on the content of the document or article and the judgment of its author. Manual extracting of keywords is costly, consumes effort and time, and error probability. In this research an automatic Arabic keywords extraction model based on deep learning algorithms is proposed. The model consists of three main steps: preprocessing, feature extraction and classification to classify the document tokens into keyword or not, Conventional Neural Networks (CNN) is used as a classifier.

Two types of dataset are building in this research to test the proposed model, the first dataset form Arab Journal for Scientific Publishing (AJSP), the other dataset from Jordan Journal of Social Sciences (JJSS). The experiment results indicate promising results in the field of Arabic keyword extraction; the average accuracy of Conventional Neural Networks is found 0.97 with average precision 0.92.

Magistrats et occupants, quelques jalons d’une comparaison diachronique (1914-1918 / 1940-1945)
Authors: Bost Mélanie , Peters Kirsten
Published: February 2022

De la période française à celle de l’après-1945, la composition sociologique du corps s’avère l’une des caractéristiques les plus stables de la magistrature belge.Les pratiques de reproduction sociale et d’endogamie, associées à un mode de recrutement fermé de la profession, ont permis l’installation de dynasties de magistrats. La stabilité politique du pays a également contribué à renforcer celle du corps judiciaire.À deux reprises, cependant, cette stabilité a été brutalement menacée. Durant les deux guerres mondiales, l’installation d’un pouvoir étranger bouleversa l’équilibre entre les pouvoirs et malmena l’indépendance de la magistrature.À partir de sources belges et allemandes, Mélanie Bost et Kirsten Peters comparent l’impact des deux occupations allemandes sur le corps judiciaire à partir de deux thématiques : la politique de nomination de l’occupant dans l’ordre judiciaire et les mesures de rigueur exercées contre certains de ses membres. Les moyens de défense des magistrats sont également examinés. La comparaison, jamais encore tentée pour l’histoire judiciaire, permet de pointer les spécificités et de dégager quelques invariants, tant dans la politique d’occupation que dans l’attitude des magistrats.

Introduction. In the context of sustainable agricultural production, agroecology aims at optimizing the economic and environmental performances of beneficial ecosystem services in order to (i) increase the productivity and resilience of cultivated ecosystems and (ii) preserve their natural resources. The maintenance of such performances is supported by research via the development of new tools that enhance plant tolerance to numerous biotic and abiotic stresses. Literature. Biostimulants can be used as a tool to complement the use of chemical inputs, by involving non-living-based products, or living-based products containing beneficial rhizosphere microbiome, such as plant growth-promoting rhizobacteria (PGPR). Pest management research has also made major advances in the development of efficient biocontrol methods. Elicitors and semiochemicals are considered to be some of the most promising tools for inducing plant resistance to various diseases and enhancing natural predation, respectively. Several products are already on the market. This review discusses current methods for exploiting and applying biostimulant and biocontrol products in contemporary agricultural systems. Future applications of these tools for sustainable management of cultivated ecosystems are also discussed. Conclusions. These tools are still difficult to use because of their lack of reliability in the field and their uneasy integration in the cropping systems. Further studies are needed to better understand the parameters influencing the efficiency of PGPR, elicitors and semiochemicals. Special attention needs to be given to the formulation and the interactions of these products with plant physiology and the environment.
L’épandage d’engrais de ferme avant le semis d’une culture intermédiaire (CIPAN) présente-t-il un risque important de lixiviation de nitrate ?
Authors: Vandenberghe Christophe , Toffoli Marc De , Lambert Richard , Colinet Gilles
Published: February 2022

Description du sujet. La transposition de la Directive Nitrates en région wallonne (Belgique) autorise l’épandage estival d’engrais de ferme à condition qu’une culture intermédiaire piège à nitrate (CIPAN) soit semée avant le 15 septembre pour préserver la qualité des eaux. Objectifs. L’étude consiste à établir si cette pratique est de nature à constituer un risque plus important que l’absence de toute intervention en période d’interculture. Méthode. L’étude s’appuie sur des mesures de reliquat d’azote nitrique dans le sol réalisées dans des parcelles de références et lors de contrôles en début de période de lixiviation ; cette mesure étant indicatrice du risque de contamination des eaux souterraines. Résultats. Entre 2008 et 2013, les analyses réalisées lors de contrôles ont montré que la présence d’une CIPAN (l’apport et le type d’engrais de ferme n’est pas connu) conduit à une médiane des observations plus faible (différence très hautement significative) que l’absence de toute intervention au cours de l’interculture. Au cours de la même période, les observations réalisées dans des parcelles de référence ont conduit à un constat similaire. De plus, dans ces parcelles de référence, il a été montré que la nature de l’engrais de ferme (à action lente ou rapide) n’engendre pas de différence significative entre les reliquats azotés moyens observés. Conclusions. L’apport d’engrais de ferme suivi du semis d’une CIPAN ne présente pas un risque plus important pour la qualité de l’eau qu’une céréale suivie d’une culture semée en automne sans CIPAN et sans apport d’engrais de ferme au cours de la courte interculture.

Published: February 2022

Description of the subject. Microevolutionary processes in metallophytes established on copper enriched soils can lead to a diversity of plant species showing distinct tolerance capacities among genus. Researches about the relationship between these endangered plants and soil copper concentrations are critical in order to improve ex situ conservation methods in southeastern Democratic Republic of Congo (Katangan Copperbelt). Objectives. The aim of the study was to test the effect of copper on the germination and root elongation of three Crotalaria species naturally occurring along a natural copper gradient. The hypothesis is that copper concentrations have different effects on germination and root elongation according to the species of Crotalaria genus. Method. Three species were selected: Crotalaria cobalticola, Crotalaria peschiana and Crotalaria cornetii, occurring on soils with the highest to the lowest copper concentrations respectively. Germination and root elongation tests were performed in vitro (MS vitamin-enriched medium) in six copper mediums ranging from 0 to 125 µM Cu2+. Results. No significant differences in germination percentage were observed according to the copper concentrations. Crotalaria cornetii had the lowest germination percentage. Root elongation of C. peschiana did not differ with copper concentration, but root elongation of C. cobalticola was higher at the greatest copper concentration (125 µM Cu2+). Conclusions. Even if C. cobalticola presented better growth at highest Cu concentrations, it appeared that C. cobalticola and C. peschiana do not require copper for their early stages of development and could thus be conserved in non-contaminated substrate. Crotalaria cornetii seemed to present a physical seed dormancy.
Influence des conditions de culture sur la production de capsules chez le cotonnier (Gossypium hirsutum L.) en conditions de culture pluviale au Bénin
Authors: Sekloka Emmanuel , Lançon Jacques , Zinsou Valérien Amégnikin , Thomas Grégoire
Published: February 2022

Description du sujet. Cet article décrit l’effet des facteurs « période de semis » et « densité » sur la répartition des capsules parvenues à maturité sur la plante de cotonnier et sur le rendement final, en prenant des variétés contrastées pour leur port et leur précocité. Objectifs. Cette étude vise à apporter un appui aux programmes de création variétale pour la culture pluviale du coton en Afrique de l’Ouest, en comprenant comment deux facteurs clés de l’itinéraire technique modifient la mise en place de la production. Méthode. Pour réaliser cette étude, quatre essais ont été conduits sur deux sites au Bénin en 2002 et 2003 avec six variétés, trois densités de culture (42 000, 125 000, 167 000 plantes·ha-1) et deux dates de semis (juin, juillet/aout) suivant un dispositif en split-split plot. Nombre de sites fructifères, taux de rétention, production et répartition capsulaire et rendement en coton graine ont été évalués. Résultats. En semis retardé, la production de capsules est réduite et celles-ci sont concentrées sur les deux premières positions des six premières branches fructifères (BF). Les fortes densités provoquent une diminution du nombre de sites, du taux de rétention et une concentration de plus de 50 % de la production sur les premières positions des quatre premières BF. Comparées aux variétés sélectionnées en Afrique (H279-1 et Irma A1042), les variétés précoces et compactes Mar 88-214 et Chaco 520 ont une proportion de capsules mûres plus élevée dans leurs parties basses (premières positions des premières BF), mais leur rendement moyen est en général plus faible. Conclusions. La sélection pour une rétention basse élevée (RP1-2_BF1-8) peut améliorer le rendement en condition de culture maitrisée et pour les variétés les moins efficientes, mais l’optimum du taux de rétention est fonction de l’itinéraire technique et, plus généralement, des conditions de culture.
Effects of arbuscular mycorrhizae on growth and mineral nutrition of greenhouse propagated fruit trees from diverse geographic provenances

Published: February 2022

Description of the subject. Arbuscular mycorrhizal (AM) fungi are known to promote plant growth by enhancing mineral uptake in nutrient deficient soils. These beneficial effects on plant growth may vary considerably between cultivars of a given species and between plant species originating from different locations. Objectives. The present experiment evaluated the response of three Sahelian fruit trees: néré (Parkia biglobosa [Jacq.] G.Don), tamarind (Tamarindus indica L.), and jujube (Ziziphus mauritiana Lam.), originating from five different geographic provenances, to mycorrhizal colonization, evaluate their respective mycorrhizal dependency (MD) and analyze their leaf and stem mineral composition. Method. Trees were cultivated in a nursery on pre-sterilized soil substrate low in available P (2.18 μg·g-1) with or without inoculum of Glomus aggregatum (Schenck & Smith emend. Koske). The experiment was arranged in a factorial design for each fruit tree species separately: 5 provenances x 2 AM treatments (inoculated and non-inoculated [control]) with 10 replicates per treatment. Plants were harvested six months after inoculation and different parameters were measured. Results. Overall, the results showed significant provenance variations in the plant response to mycorrhizal inoculation. Néré mycorrhizal plants, from two seed sources, tamarind and jujube plants from one seed source had significant higher dry weight and shoot height than those from other provenances. Jujube plants from 3 out of the 5 provenances showed significant higher MD. It then appears that seed provenance happened to be determinant even though AM-root colonization levels (80-90%) do not vary much from one provenance to another. In all cases, the fruit trees benefited from AM fungi with increased N, P and K mineral uptake in aerial parts. In particular P uptake was proportional to MD concentration in AM-jujube plants. Conclusions. These results demonstrate the importance of considering seed provenance when performing pre-selection of mycotrophic plant candidates prior to large-scale fruit tree propagation in orchards and agroforestry systems.

Description of the subject. Drought is one of the major abiotic factors affecting growth and productivity of plants by imposing certain morphological, physiological and biochemical changes at different growth stages. Objectives. The objective of this work is to study key morphological, physiological and biochemical responses of faba bean (Vicia faba L. var. ‘minor’) to soil water deficit stress and to assess the contribution of genetic factors in improving faba bean tolerance to water deficit. Method. Plants of 11 faba bean cultivars were grown in the greenhouse and subjected to three levels of water deficit (90, 50 and 30% of field capacity [FC]) in a simple randomized design for 20 days. Water deficit effects on plant growth, relative water content (RWC), gas exchange, chlorophyll a (Chla) and chlorophyll b (Chlb) content, osmoprotectant accumulations (such as proline and soluble sugars), antioxidant enzyme activities and grain yield were determined. Results. Soil water deficit stress reduced growth and affected physiological parameters, especially antioxidant enzyme activities. Water deficit also increased proline, soluble sugars and protein contents. The studied cultivars significantly differed in their responses to water deficit stress. Photosynthetic parameters were less affected in the ‘Hara’ cultivar. Furthermore, this cultivar produced the highest value of grain yield at 30% FC, and showed higher antioxidant enzyme activities (CAT, GPX and APX), osmoprotectant accumulations, Chlb and RWC. The ‘Hara’ cultivar was found to be more tolerant to water deficit stress than the other cultivars. Conclusions. Our methodology can be used for assessing the response of faba bean genetic resources to soil water deficit. The identified tolerant cultivar can be utilized as a source for water stress tolerance in faba bean breeding programs aimed at improving drought tolerance.
Cloning of a novel gene from Penicillium oxalicum I1 which in Escherichia coli enhances the secretion of acetic acid
Authors: Xue Liu , Chang-xiong Zhu , Ming-bo Gong
Published: February 2022

Description of the subject. Organic acids play an important role in the conversion of insoluble ions into soluble ones in soil. Heterologous overexpression of a single gene in a cell is the optimal strategy for increasing the secretion of organic acids solubilizing phosphate. Objectives. In this study, we constructed a primary cDNA library of Penicillium oxalicum I1, and screened clones that can solubilize P in tricalcium phosphate (TCP) medium. We aimed to obtain the gene expressed in Escherichia coli, which can enhance organic acid secretion. Method. A primary cDNA library of Penicillium oxalicum I1 was constructed using the switching mechanism at the 5'-end of RNA transcription. The organic acid secretion ability of E. coli DH5α™ with overexpressed P. oxalicum I1gene was tested in TCP medium where glucose is the sole carbon source. Afterwards, pyruvic acid, citric acid, α-ketoglutaric acid, succinic acid, fumaric acid, and malic acid were used as sole carbon source substitutes for glucose in the TCP medium to test the organic acid secretion ability of the transformed E. coli DH5α™. Results. A total of 106 clones showed halos in TCP medium, among which clone I-2 displayed clear halo. The full-length cDNA of clone I-2 was 1,151 bp, with a complete open reading frame of 702 bp, which encoded a hypothetical protein of 233 amino acids. The cDNA sequence showed 68% identity and 73% query cover with other fungal gene sequences of which the function remains unknown. Escherichia coli containing the cloned gene secreted up to 567 mg·l-1 acetic acid within 48 h. The use of glucose, pyruvic acid, α-ketoglutaric acid, and malic acid improved the acetic acid secretion of the E. coli DH5α™ clone I-2. By contrast, the use of citric acid, succinic acid, and fumaric acid did not improve the acetic acid secretion of clone I-2 compared to a control E. coli DH5α™ strain bearing only the cloning vector without any insert. Conclusions. We obtained a novel gene from Penicillium oxalicum I1 whose overexpression in E. coli DH5α™ increased the secretion of acetic acid. This observation should help to understand what is the function of the gene isolated from P. oxalicum as well as that of its homologs found in several other species of the Penicillium genus.

Authors: Shikhalieva D. S. , Belyaeva S. V.
Published: February 2022

The article examines the causes and consequences of such an economic phenomenon as an economic crisis. The problem of economic crises is determined by the fact that, despite the tools created by the world community to prevent them, it is impossible to accurately predict, much less avoid, economic disasters. The article characterises the crises in Russia from 1998 to 2021. Since 1998, there have been four different causes of crisis in the new economic history. It has shown that world economic crises directly or indirectly affect the macroeconomic indicators of the Russia, cause their decrease. It has concluded that the Russian economy is more responsive to the economic macro-conjuncture due to the dependence of the ruble on the dollar, and the impact of the level of commodity prices on the income part of the consolidated budget.

Published: February 2022

Since there is an active trend of increasing derivative instruments in the Russian derivatives market, the object of this study was exchange-traded and over-the-counter derivatives in Russia, and the purpose of the study – the development of their application. To achieve this goal, such scientific research methods as analysis, comparison, description and historical method are used. The most important conclusions of the study are that the derivatives market has developed rapidly since 2013, but in 2021 it witnessed a significant increase due to the appeal of a large number of investors to invest in financial markets, and due to increased concern about the volatility of the exchange rate, due to which many dealers dealing in derivatives buy these instruments sometimes for the purpose of hedging, and at other times for the purpose of speculation or both.

Published: February 2022

The study examines the practices and problems of online involvement of the population in the activities of non-profit sector organisations depending on socio-demographic characteristics based in statistical observation, and data from a sociological survey on the territory of the Vologda region. It has been substantiated that when implementing socially significant projects and events, it is advisable for non-profit organisations to assess the territorial features of digitalisation, the possibilities of potential and target audiences. A toolkit for assessing the involvement of the population in the activities of non-profit organisations in the digital environment has been proposed based on the analysis of three parameters: awareness, goal-setting, and the effectiveness of online platforms and its approbation has been carried out. A portrait of a user of the network resources of non-profit organisations has been presented. It has been concluded that at present society is more focused on the implementation of the practices of civic participation in real, and not in the virtual space, which is shown by the experience of non-profit organisations.

Effective self-marketing model
Authors: Gladkova L. A.
Published: February 2022

The purpose of the article is to develop a theoretical model of effective self-marketing with the allocation of specific blocks, factors and results of career development. Currently, there is no system model of the self-marketing process within the framework of existing concepts, which limits the possibilities of developing scientifically based proposals for its effective technology. The formation of the model consists of three stages. Stage I – “Self-orientation”, takes into account the individual psychological characteristics of the individual, which relates to the sphere of the subject of labor and is implemented through introspection, career strategy planning and self-organisation. Stage II – “Orientation to career conditions”, takes into account the requirements of the sphere of professional activity and is implemented by analysing the conditions of the career environment and career space. Stage III – “Self-expression in the career space”, taking into account the requirements of the professional sphere and one’s own identity, involves managing an individual image, and self-presentation of the subject of labor. It is proposed to evaluate the result of self-marketing on the basis of a combination of objective and subjective criteria: the degree of achievement of the set goals of professional activity and the experience of satisfaction with its results.
Towards hydrogen and halogen bonded frameworks based on 3,5-bis(triazolyl)pyridinium motifs
Authors: Foyle Emer , Tay Hui Min , White Nicholas
Published: February 2022

We attempted to use hydrogen, iodo and seleno 3,5-bis(triazolyl)pyridinium (btp) motifs to form 3D supramolecular frameworks assembled by hydrogen, halogen or chalcogen bonding to anions. Initially, we prepared flexible ditopic and tetratopic receptors where the pyridinium nitrogen atom was functionalized with a benzylic group but were unable to crystallise extended frameworks. We subsequently developed the use of Zincke methodology to prepare rigid ditopic and tetratopic hydrogen and halogen bonding tectons, and were able to crystallize the sulfate derivative of a tetratopic receptor, although unfortunately this did not have the desired open framework. Several crystal structures were obtained with the receptors and monovalent anions, including one containing an unusually short iodotriazole∙∙∙Cl– halogen bond. Generally, the btp triazole groups show a tendency to rotate away from the desired conformation and it appears that this may contribute to difficulties in obtaining 3D frameworks even when the receptors have a rigid core.
Applicability Domain of Polyparameter Linear Free Energy Relationship Models Evaluated by Leverage and Prediction Interval Calculation
Authors: Endo Satoshi
Published: February 2022

Polyparameter linear free energy relationships (PP-LFERs) are accurate and robust models employed to predict equilibrium partition coefficients (K) of organic chemicals. The accuracy of predictions by a PP-LFER depends on the composition of the respective calibration data set. Generally, extrapolation outside the model calibration domain is likely to be less accurate than interpolation. In this study, the applicability domain (AD) of PP-LFERs was systematically evaluated by calculating the leverage (h) and prediction interval (PI). Repeated simulations with experimental data showed that the root mean squared error of predictions increased with h. However, the analysis also showed that PP-LFERs calibrated with a large number (e.g., 100) of training data were highly robust against extrapolation error. For such well-calibrated PP-LFERs, the common definition of extrapolation (h > 3 hmean, where hmean is the mean h of all training compounds) may be excessively strict. Alternatively, the PI is proposed as a metric to define the AD of PP-LFERs, as it provides a concrete estimate of the error range that agrees well with the observed errors, even for extreme extrapolations. Additionally, published PP-LFERs were evaluated in terms of their AD using the new concept of AD probes, which indicated the varying predictive performance of PP-LFERs in existing literature for environmentally relevant compounds.

Authors: Salas-Rueda Ricardo-Adán , De-La-Cruz-Martínez Gustavo , Alvarado-Zamorano Clara , Prieto-Larios Estefanía
Published: February 2022

Nowadays, teachers seek to improve learning conditions and build new educational spaces through technological advances. This mixed research aims to analyse students’ perceptions about the use of the collaborative wall in the teaching-learning process for physics, considering data science. The collaborative wall is a web application that allows the participation of the students in the classroom through the dissemination of text and images. The participants are 77 students of the National Preparatory School No. 7 ‘Ezequiel A. Chávez’ who took the course of Physics IV during the 2019 school year. At home, these students searched for and consulted information about the physics of hearing in order to create their infographics collaboratively using the Piktochart software. During the face-to-face sessions, the teacher of the course of Physics IV requested the creation of teams (maximum six members) to carry out the collaborative activities and used the projector to show the collaborative wall. Subsequently, each team uploaded their infographics on the collaborative wall through mobile devices such as tablets and smartphones to initiate the discussion of the Physics of Hearing topics. The results of machine learning (linear regression) indicate that the dissemination of infographics on the collaborative wall positively influences participation in the classroom, students’ motivation, and the learning process about the physics of hearing. Data science identifies three predictive models about using the collaborative wall in physics through the decision tree technique. Finally, the collaborative wall facilitates the active role of the students during the face-to-face sessions, communication in the classroom and realisation of the collaborative activities.

The implementation of character education is the duty and responsibility of educational institutions, in accordance with applicable laws and regulations and demands in the era of globalization. In addition, the role of educators, academic staff and institutions has an important role in developing methods for implementing character education in higher education. So that what is expected by the government regarding the outcomes of higher education institutions that have strong knowledge and character is realized. The government holds the hope that every graduate from higher education will have the ability to develop character and knowledge well. However, what has happened recently, is very different from the expected expectations. This phenomenological analysis hopes to provide an overview regarding the development of the value clarification technique (VCT) model in midwife education. So that the six main characters can be applied to midwife education, especially the characters of respect, respect, fairness, caring, and citizenship. Because some of the research results related to the VCT model turned out to be able to increase the value possessed by students at the primary and secondary education level. Therefore, the contribution of this paper is in efforts to develop a VCT model in higher education, in realizing the golden generation in 2045.

Published: February 2022

Objective ‒ to study the effect of ruptured aneurysm localization, severity of hemorrhage and aneurysm occlusion method on the probability of developing shunt-dependent hydrocephalus (SDH) and to assess the prognostic sensitivity of clinical and radiological scales.Materials and methods. The results of treatment of 597 patients with aneurysmal subarachnoid hemorrhage (SAH) of varying severity were analyzed. In 282 cases endovascular occlusion of the aneurysm was performed, in 315 ‒ microsurgical clipping. A group of 63 patients who required implantation of the ventriculoperitoneal shunt system within 3 to 15 weeks after aneurysm rupture was selected.Results. Of the patients who underwent coiling of the ruptured aneurysm, 22 (7.8 %) required implantation of the cerebrospinal fluid shunt system, and 41 (13.0 %) of the patients who underwent microsurgery. The mean age of patients in the endovascular occlusion group was 64.28 years, in the microsurgical clipping group ‒ 50.64 years. The localization was dominated by aneurysms of the anterior communicating artery (ACA) complex ‒ 37 (58.7 %) observations, internal carotid artery ‒ 15 (23.8 %), vertebrobasilar basin (VBB) ‒ 9 (14.3 %) and the middle cerebral artery ‒ 2 (3.2 %). The predominance of aneurysms of the ACA complex among those operated by microsurgical method (29 (70.7 %)) and VBB aneurysms among those operated on endovascularly (9 (40.9 %)) was revealed. Rupture of the aneurysm was complicated by massive SAH in 20 (31.7 %) cases, subarachnoid-parenchymal hemorrhage ‒ in 7 (11.1 %), subarachnoid-ventricular ‒ in 4 (6.4 %), subarachnoid-parenchymal-ventricular ‒ in 32 (50.8 %). The distribution by severity of hemorrhage on the Hunt‒Hess scale was as follows: grade II ‒ 10 (15.9 %) cases, grade III ‒ 26 (34.9 %), grade IV ‒ 27 (49.2 %). According to the Fisher radiological scale, grade III hemorrhage was noted in 20 (31.7 %) cases, IV ‒ in 43 (68.3 %) cases. Analysis using the Graeb scale showed the absence of blood in the ventricular system in 27 (42.9 %) cases, 1‒3 points ‒ in 9 (14.3 %), 4‒6 points ‒ in 12 (19.0 %), 7–12 points ‒ in 15 (28.8 %).Conclusions. Rupture of aneurysms of the ACA complex, accompanied by severe complicated SAH in patients operated on by microsurgery, and aneurysms of the VBB in persons operated on endovascularly, increases the risk of SDH. Endovascular occlusion of ruptured aneurysms does not increase the risk of SDH. The severity of hemorrhages of III–IV degree on the Hunt‒Hess scale and III–IV degree on the Fisher scale are predictors of SDH development.

Today, thanks to the development and implementation of new modern instrumental research methods in the daily practice of doctors, such as computed tomography with angiography, multispiral computed tomography, ultrasound examination of vessels with duplex scanning, celiacography, upper and lower mesentericography, etc. Every year, the information content of the above examination methods is growing, which will certainly lead to an increase in the frequency of detecting rare vascular pathologies that cause hemobilia. The method of treatment for this vascular pathology is endovascular embolization using embolizing coils and substances. A clinical case of a multidisciplinary approach to diagnosis and endovascular treatment is presented. a. gastroduodenalis with the formation of a pseudo-aneurysm (40 × 20 mm) with antegrade blood flow along a.pancreaticoduodenalis superior and a.gastroepiploica dextra distal to the aneurysm of a 28-year-old patient who was urgently hospitalized in the surgical department of Kyiv Regional Clinical Hospital. After the surgical treatment against the background of conservative treatment, the patient’s general condition improved and the hemoglobin level increased. A multidisciplinary approach helps to choose the right tactics for managing a patient, even with such a rare vascular pathology that has led to hemobilia. The gold standard for diagnosis and treatment hemobilia is angiography and endovascular embolization, which can be an alternative to open surgery, minimizes the risk of postoperative complications and reduces the rehabilitation period. If it is impossible to carry out the above technique or its ineffectiveness, further treatment is surgical.

Translocation (including transportation and experiencing a new environment) represents a significant stressor for animals. The aim of this study was to assess changes in corticosterone metabolite (CM) levels related to translocation in common pheasants (Phasianus colchicus). Sixteen birds (8 males and 8 females) aged 17 weeks were crated and transported for 3.5 h (distance travelled 140 km) to the target customer. Serial individual droppings were collected from 2 days prior until 3 days after transport. Concentrations of CMs in droppings were determined with a non-commercial cortisone enzyme immunoassay (EIA). Transport stress resulted in increased CM concentrations in the droppings in our study. The CM concentrations significantly increased within 2.5 h of transport (P < 0.01) compared to pre-transport levels (747 ng/g vs. 187 ng/g). After additional 3 h, the CM concentrations fell back to the baseline levels (207.7 ng/g). In the new environment, the second peak (median: 1383 ng/g) was determined with CM concentrations increasing (P < 0.01) compared to baseline levels. This increase was likely connected to the stress resulting from the new environment. The CM levels returned back to the baseline level 26 h after the start of transportation. No differences in concentrations of CM between sexes were found in our study. The utilized cortisone EIA proved suited to detect biologically meaningful alterations in adrenocortical activity of pheasants exposed to procedures related to their transport.
