Bretagne, fragile bastion de l'écologie politique
Authors: Kernalegenn Tudi
Published: November 2019

La Bretagne est souvent considérée comme un bastion écologiste. Pourtant, malgré leurs scores électoraux notables, les Verts bretons sont peu présents dans les institutions. Si les écologistes ont, ces dernières décennies, favorisé l’évolution de la région vers la gauche et d’une gauche intégrant une sensibilité environnementaliste et régionaliste, ils n’en restent pas moins une force politique secondaire à cause de leurs divisions internes historiques et de la forte domination du PS.
Mineurs isolés, l’hôtel pour seule protection
Authors: Angliviel Maud , Ducci Solène
Published: November 2019

Bien que les répercussions de la vie en hôtel social soient aujourd’hui connues (difficultés scolaires, instabilité, etc.), de plus en plus de mineurs isolés étrangers y sont hébergés au titre de leur prise en charge par les services de la protection de l’enfance. Une prise en charge minimaliste, inadaptée aux besoins de ces adolescents.
La Cour de l’asile, une usine à décisions
Authors: Berthe Léo
Published: November 2019

Comme toutes les institutions traversées par la question migratoire, la Cour nationale du droit d’asile n’a pas échappé à la logique comptable qui s’est peu à peu imposée dans ce domaine. Réduire les délais d’examen des demandes d’asile, non pour juger mieux et dans un temps raisonnable mais pour faire du chiffre : tel est l’unique objectif des pouvoirs publics, quel qu’en soit le coût pour les personnels et les demandeurs d’asile.
Le mouvement démocratique chinois au miroir des révolutions de 1989
Authors: Veg Sebastian
Published: November 2019

Alors que l’effondrement des régimes communistes a servi de repoussoir à l’État chinois, de nombreux intellectuels s’interrogent sur les raisons de l’échec du mouvement démocratique en Chine. Les écrits de Vaclav Havel ont été traduits et discutés parmi les intellectuels libéraux (Liu Xiaobo) ; l’expérience polonaise a inspiré d’autres militants (Han Dongfang) à se tourner vers le syndicalisme indépendant. Des universitaires se sont essayé à des études comparatives des réformes économiques en Chine et dans l’ex-bloc soviétique. À travers ces débats, l’expérience historique des sociétés communistes d’Europe reste l’un des points de repère de la réflexion politique en Chine depuis 1989.
Révolutions de 1989 et restructurations de l’espace de la cause cubaine
Authors: Geoffray Marie-Laure
Published: November 2019

La « cause cubaine », portée avant tout par la diaspora cubano-américaine politisée, a longtemps pâti d’une faible légitimité à l’international du fait de son encastrement dans la politique étrangère américaine. A partir de 1989 cependant, l’interprétation des révolutions à l’Est par une partie de cette diaspora la pousse à internationaliser la cause et à construire des coalitions transnationales, avec le soutien des anciens dissidents d’Europe centrale. Il s’agit de gagner en légitimité d’une part, et de bénéficier de leur expérience et expertise d’autre part pour renverser le gouvernement communiste cubain. Cette stratégie favorise la transnationalisation de la cause, désormais prise en charge dans de nombreux espaces sociaux et politiques bilatéraux et multilatéraux en Europe et dans les Amériques. Néanmoins, le succès de cette extension de la prise en charge de la cause a aussi eu pour corollaire un affaiblissement de sa consistance et entraîné une certaine fragmentation.
Pourquoi les dirigeants s’imitent-ils ? Réponse de la théorie mimétique de René Girard
Authors: Ben Ammar Sameh , Ben Kahla Karim
Published: November 2019

En dépit du rôle important qu’il joue dans de nombreuses théories des organisations, le mimétisme inter-organisationnel n’a pas fait l’objet d’une conceptualisation bien développée. L’objet de cet article est d’améliorer la compréhension du phénomène de mimétisme dans un contexte concurrentiel en faisant appel à la théorie mimétique de René Girard. Nous cherchons à explorer le mimétisme dans les décisions des dirigeants en faisant appel à une recherche interdisciplinaire. Nous présenterons, dans ce travail, dans une première partie une revue de la littérature managériale relevant du mimétisme inter-organisationnel. La seconde partie est consacrée à la théorie mimétique de Girard. Dans la troisième partie, nous discutons les résultats de notre étude qualitative portant sur la dimension mimétique dans le comportement des dirigeants de PMEs tunisiennes du secteur de l’ameublement. La transposition de la thèse girardienne à ce champ d’investigation nous a permis d’intégrer de nouvelles variables jusqu’ici peu utilisées par les chercheurs en stratégie : le désir mimétique, la distance entre le sujet et le modèle, la rivalité mimétique et la crise mimétique.
Typologie des créatrices d’entreprise djiboutiennes en termes de potentialités entrepreneuriales : importance des antécédents familiaux et professionnels
Authors: Dokou Gérard Akrikpan Kokou , Mahamoud Rayaleh Abdourahman
Published: November 2019

L’article cherche à expliquer les types d’antécédents familiaux et professionnels qui impactent les potentialités de l’entrepreneure djiboutienne et qui font émerger une typologie des créatrices en présence. Elle consiste d’abord à effectuer une synthèse des principaux travaux relatifs aux paradigmes des traits et des faits de l’entrepreneur pour mieux resituer le modèle conceptuel de Gasse (Gasse et D’Amours, 2000). Dans un second temps, le travail de terrain se focalise sur l’exploitation d’une enquête réalisée auprès de 208 entrepreneures djiboutiennes. C’est un questionnaire de 120 items hors facteurs d’identification. Les items sont articulés autour de 15 dimensions réparties entre 5 axes (motivations, aptitudes, attitudes, intérêts et comportements). Le traitement des données s’est appuyé sur les techniques statistiques descriptives (tris à plat et tris croisés) et multidimensionnelles (analyse des corrélations, analyse en composantes principales, la classification hiérarchique et l’analyse discriminante). Les résultats issus de ces différentes méthodes d’analyse de données consolident le modèle conceptuel initial et ouvrent des perspectives en termes de pédagogie d’accompagnement de l’entrepreneure africaine souvent soumise aux pesanteurs contextuelles.
Le concept de la carrière protéenne : quelle portée compréhensive ? Cas des cadres de la génération Y au Maroc
Authors: Boutannoura Rachid , Bentaleb Chafik
Published: November 2019

Face aux mutations socioéconomiques et leurs effets sur le marché de l’emploi, plus d’une dizaine de concepts « nouveaux » ont vu le jour pour comprendre la notion de carrière. Néanmoins, malgré la multitude de modèles qui cherchent à expliquer les carrières contemporaines, seuls quelques concepts sont largement reconnus. C’est le cas du concept de « carrière protéenne » sur lequel notre article se focalise. En s’attardant sur deux méta-compétences, notre travail cherche à mettre ce concept à l’épreuve en le confrontant à un échantillon de jeunes cadres marocains issus de la génération Y. Cette recherche exploratoire fait ressortir l’importance des dimensions subjectives et intersubjectives pour comprendre le nouveau rebond des plans de carrière. D’un point de vue empirique, on s’interroge sur le poids des éléments de contextes locaux dans le processus de création de sens associé à la carrière des nouveaux collaborateurs. Nous soutenons que la mobilisation d’une approche contextuelle et enracinée du concept de la « carrière protéenne » permet aux chercheurs d’enrichir les modèles existants et, par conséquent, de répondre par une vision plus holistique des carrières.
Le courage à l’épreuve de l’expérience
Authors: Ribas Marie-Noëlle
Published: November 2019

Cet article se propose d’étudier comment Platon, Aristote et Thucydide participent à la remise en question du rôle prépondérant accordé au courage dans le domaine militaire avant la guerre du Péloponnèse. Le courage n’est rien sans le savoir ni l’expérience. Telle est la thèse que ces trois auteurs déclinent chacun à leur manière, qu’il s’agisse pour Platon d’interroger la dimension intellectuelle du courage, pour Thucydide d’établir la complémentarité du courage et de l’expérience, ou, pour Aristote, de faire de la connaissance des particuliers qu’est l’expérience le premier critère dans la désignation des stratèges.
Introduction au dossier spécial ADERSE 2018 « Gouvernance et RSE »
Authors: Baret Pierre
Published: November 2019

Dans le cadre de la Semaine du Management organisée par la FNEGE à la Cité Internationale de Paris, s’est déroulé du 22 au 23 mai 2018 le 15ème Congrès de l’ADERSE sur le thème « Gouvernance et RSE ». 114 communications y furent présentées. Une majorité d’entre elles traitèrent de sujets connexes au thème du Congrès. Ainsi fût-il débattu de la gouvernance partenariale et du rôle des administrateurs, de l’éthique de la gouvernance, de la gouvernance publique ou privée des territoires, de la gouvernance responsable, etc. Mais beaucoup d’autres sujets furent également abordés. Sans être exhaustif, citons pêle-mêle l’implication des parties prenantes dans les démarches responsables, les liens entre RSE et stratégie, la RSE comme source d’innovations, les comportements non-éthiques, les normes comme vecteur de RSE, les approches institutionnelles de la RSE, les achats responsables, l’économie circulaire, l’enseignement de la RSE, l’action sociétale, les relations de proximité dans un cadre responsable, les impacts de la RSE sur la performance financière, le pilotage et le reporting extra-financier, la performance globale, etc.
The use of publicly available information for human capital analysis: case of three Australian companies
Authors: Hatipoglu Burcin
Published: November 2019

Cet article fait l’hypothese que les performances futures d’une organisation ne peuvent être fondées uniquement sur le respect des exigences obligatoires, en ignorant d’autres indicateurs précieux tels que le capital humain. L’analyse des rapports annuels et des sites web de trois sociétés australiennes indique que celles-ci se conforment aux réglementations obligatoires et aux recommandations de gouvernance d’entreprise de l’ASX pour la période 1999-2004. L’étude des rapports annuels et des rapports de développement durable d’entreprises montre que ce sont des sources valables de collecte d’informations sur la stratégie d’entreprise, les mécanismes de gouvernance d’entreprise, les programmes de restructuration, les performances sociales et environnementales, les préoccupations professionnelles et sanitaires, ainsi que les performances économiques. En revanche, ils fournissent peu d’informations sur le capital humain en plus de la rémunération obligatoire des dirigeants et des administrateurs. Les connaissances nécessaires en capital humain utilisées pour analyser les données de cette recherche (les indicateurs de caractéristiques d’emploi, le recrutement, la formation, les perspectives de carrière, les récompenses et l’identité et la culture professionnelle) ne font pas systématiquement partie des exigences de déclaration obligatoire ni du processus d’investissement. L’utilisation de données qualitatives avec des données quantitatives pourrait réduire pourtant l’asymétrie de l’information entre les gestionnaires et les investisseurs.
Fabricating Ultra-Smooth Diamond-Like Carbon Film and Investigating its Antifungal and Antibiofilm Activity
Authors: Akkam Yazan , Alshurman Khaled
Published: November 2019

Diamond like carbon (DLC) a carbon-based nanomaterial has been nominated as a potential solution to prevent the biofilm formation on indwelling medical devices such as dentures and heart valves. Candida albicans is an opportunistic fungal pathogen where biofilms are a part of its pathogenicity which primarily utilized indwelling medical devices as platform to build up the biofilm. In this work, DLC deposited on silicon substrate was prepared to accomplish the optimal characteristics for bio-coating material (roughness, purity, uniformity) and then evaluated for their ability to prevent or reduce the biofilm formation of pathogenic C.albicans (SC5314) under conditions mimicking human body. Optimized DLC was synthesized via chemical vapor deposition, and then the film was characterized by Raman spectroscopy, scan electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX), and atomic force microscopy (AFM). The potential biofilms on DLC, silicon substrate and positive control (polyvinyl chloride-PVC) were quantified via colorimetric cell viability assay (XTT); as intact and vortexed biofilms. The characteristics of formed biofilms were carried out using confocal scanning laser microscopy (CSLM) and scan electron microscope (SEM). The result showed that DLC was successfully deposited on the silicon substrate with a root mean square (RMS) roughness of 0.183± 0.09 nm. The biofilm efficaciously grown on all samples (DLC and positive control) with thickness of 46.8 ± 6.97 μm and 42.18 ± 4.65 μm, respectively. No topological and morphological changes have been observed by SEM on biofilm-DLC compared to PVC-biofilm. Moreover, all results indicated that the hydrophobicity and roughness of DLC appeared to support the attachment and the growth of C.albicans .In conclusion , there is no privilege of utilizing DLC over PVC in term of reduction or inhibition of C.albicans biofilm formation at physiological conditions. Furthermore, this study may serve as an experimental model to evaluate the potential effect of nanomaterials coating on biofilm formation at conditions mimicking human’s body.

Authors: Yousif Hayder A. , Norasmadi Abdul Rahim , Bin Salleh Ahmad Faizal , Zakaria Ammar
Published: November 2019

The main goal of this research work is to study and evaluate the muscles force and fatigue of Gastrocnemius Medialis (GMS), Gluteus Maximus (GM), and Gastrocnemius Lateralis (GL) during running for 400-meters based on surface Electromyography (sEMG) signals. The sEMG signals of the selected muscles from the right leg have been collected by using bipolar electrodes from 15 subjects during the run on the tartan athletic track with two pacing strategies. The first strategy: 1st 200-meters running 87% - 94% of full speed and last 200-meters sprinting (full speed). The second strategy: 1st 300-meters running 87% - 94% of sprinting and last 100-meters sprinting. The rate of fatigue has been calculated by using Root Mean Square (RMS) and Median Frequency (MDF) features. Then, the slopes of linear regression were calculated from both RMS and MDF at each 100-meters. The linear slope values represented the rate of fatigue and force. From the results of 1st and 2nd running strategies, the force of GM and GL muscles increased during the 4th 100-meters of the 1st strategy and decreased with GM and GMS muscles during the 4th 100-meters of the 2nd strategy. The less index fatigues were during the 1st strategy for most selected muscles. Finally, it can be concluded the running with the 1st strategy get less fatigues and the force of most selected muscles increased compared with the 2nd strategy based on the results of time and frequency domain features (RMS and MDF).
Digital Image Analysis for Morphological State Characterization of a Culture of Filamentous Microorganisms in Production of Antibiotics
Authors: Nahlik Jan , Kukal Jaromír , Kohout Jan , Mareš Jan , Hrnčiřík Pavel , Vařacha Pavel
Published: November 2019

The paper deals with the application of specific methods of digital image analysis for the monitoring of morphological changes in cultures of filamentous microorganisms. First, a sequence of digital image preprocessing and processing steps is proposed for the treatment of microscopic images of a filamentous culture. The preprocessing step include band pass filtering by the Difference of Gaussians filter featuring a novel approach to the task of parameters tuning, as well as the optimization of image porosity and image objects separation quality. In the processing step, the resulting enhanced images are subject to morphological state characterization using a set of several standard and modified morphological parameters. Descriptions of morphological states of different complexity are then discussed varying from the standard set of mean values of parameters to the set of parameters in their full histogram of value frequencies (distribution) form. For such complex descriptions also new fashions of graphical representation of results without loss of information are compared. The potential of the proposed full description of morphological behavior of the culture is demonstrated using a set of microscopic images taken during an industrial antibiotics production cultivation using a microorganism belonging into the Streptomyces genus. Finally, the cluster analysis is proposed for further automatic quantitative classification and interpretation of complex description of metabolic states.

Authors: Korolev Albert V. , Balayev Andrei F. , Iznairov Boris M.
Published: November 2019

This paper discusses the technological method of residual stress relaxation of bearing rings by centerless running with cylindrical rolls. Described a new approach to relieve residual stresses by centerless running of elastically-deforming rolls on the basis of the geometrical setup of the equipment. It was found that geometrical setup of the equipment influences an elastic strain of parts and the degree of residual stress relaxation. We obtained a mathematical model for calculation of setup parameters to ensure the required variation value of elastic strain of the part. The results of experiments confirm the influence of the geometric setup on the magnitude of residual stress relaxation.
Surgical Denervation of Spermatic Cord for Chronic Scrotal Content Pain: A Modified Technique
Authors: Ahmed Ehab M. , Alsayyad Ahmed J.
Published: November 2019

Microsurgical denervation of the spermatic cord has been described as a treatment modality for patients with chronic scrotal content pain. The aim of our study is to evaluate a modified technique by performing denervation of the spermatic cord without a surgical microscope in patients with chronic scrotal content pain as a simplified modality. This retrospective study included 20 patients who underwent denervation of spermatic cord without using surgical microscope for treatment of intractable chronic scrotal content pain. Post denervation pain was assessed 6 months after the surgery. Twelve (60%) patients reported complete alleviation of the symptoms, four (20%) patients noticed more than 50% improvement in their symptom, two (10%) patients had less than 50% improvement, and two (10%) patients reported no changes in their complaint. In conclusion, denervation of the spermatic cord without using surgical microscope is simple and feasible and shows comparable results to microsurgical denervation in treating patients with chronic scrotal content pain. Further studies are needed to confirm the efficacy of this modality.
Online Assessment of Scientific Reasoning Skills and Motivation to Learn Science among Grade 5 and 7 Students in Northern Namibia
Authors: Kambeyo Linus , Csapó Benő
Published: November 2019

This study aimed to assess students’ scientific reasoning skills using an online assessment method and explore the relationship between their reasoning skills and motivation to learn science. Research participants were 270 Grade 5 and 346 Grade 7 students in the Oshana region of Namibia. The online reasoning skills test consisted of 36 items with 16 tasks assessing conservation, proportional, correlational and probabilistic reasoning, and logical operations in a science context. The five point Likert scale Science Motivation Questionnaire II consisted of 25 items with five subscales. Tasks were developed within and delivered by the eDia platform via the Internet. The reliability of the reasoning skills test was acceptable (Cronbach’s alpha=.74), and it was very good for the Science Motivation Questionnaire (Cronbach’s alpha=.91). The reasoning skill tasks were moderately difficult for the students: M=40.56%; SD=13.47%. One-parameter Rasch analyses showed that there were few items to differentiate students at the low skill levels. Task analysis showed major obstacles in students’ reasoning skills for science learning. Students reported that they were moderately motivated to learn science. A weak correlation was found between the tested scientific reasoning skills and motivation to learn science (r=.21, p<.01). The study suggests that the basic ICT infrastructures in Namibian schools should be improved to exploit the advantages of online assessment.
NATIONAL SECURITY OF THE REPUBLIC OF POLAND
Authors: Tuz, PhD Brig. Gen. (ret.) Andrzej
Published: November 2019

Issues related to national security problems have long been of interest to many research
centres. National security, due to its role and importance for the functioning of both the
state and society, has become an important research area not only for military specialists,
but also civilian experts. However, despite the unquestioned principle of the need
to study the problems of national security, dispute issues are increasingly appearing
that require new solutions based on scientific foundations or a fuller interpretation of
the applicable rules of conduct. Security as a research area is multidimensional, it is
analysed primarily in terms of organisation and subject. Therefore, there is no doubt
the thesis that ensuring security is a fundamental duty of the state, because it really
determines the sense of its existence. The security of the state is of course also the
security of its citizens. Since the dawn of human history, the security of the individual
has been associated with state-forming processes. Unfortunately, security, like many
other common phenomena of everyday life of individuals and societies is intuitively
made aware and does not succumb to unambiguous definitions, which is why a
number of discussions arise and not only in the scientific community. The national
security of the Republic of Poland is a specific range of challenges generated for the
state. The article looks at the conditions of external and internal national security of
the Republic of Poland, which is the starting point for research on national security.
National security was defined and its typology made.
MARKET MANAGEMENT IN MARKET ACTIVITY

The article points to the social aspects of marketing in the market activity of business
entities. It results in the processual character of management in the exchange of
products (values) between two sides of the market (demand and supply), which
consists of two market groups (two groups of people). It is these groups of people that
are the subject of management, including those involved in the implementation of its
basic functions, necessary for the implementation of the objectives of market activity.
This subjective character of management was presented in selected economic entities.
EVOLUTION OF THE AERIAL DEFENCE OF AIR BASES.
CONCEPTS AND LESSONS LEARNED
Authors: KOŁATA, LTC, MSc, Eng Grzegorz
Published: November 2019

The lessons learned during wars and armed conflicts indicate that the main factor
influencing the aerial defence of air bases were directly related to the rapid development
of the combat capabilities of aerial threats. Air bases have been lucrative targets for enemy
air strikes since the first documented attack by a British aircraft on a German airfield in
1914 and have remained so for contemporary military air operations. The article discusses
the evolution of concepts and lessons learned in the field of aerial defence of air bases that
resulted from armed conflicts and local wars. The analysis includes armed conflicts, which,
according to the author, have reflected the changes in the organisation of the aerial defence
of air bases, including the repulsion of air strikes against aviation on the ground. Attention
was paid to the conditions related to the aerial defence of aviation on the ground during
the First World War. A more thorough analysis was made of the Second World War period,
focused on the Western Front and the defence of Poland. Particular attention was paid to
the Battle of Britain, noting the importance of the organisation of the radar air surveillance
system in the context of the effectiveness of air defence. The focus of the analysis then
shifts to the aerial defence of air bases during armed conflicts after the Second World War:
the Vietnam War (1965-1973), the Yom Kippur War (1973), the defence of air bases in
the Yom Kippur War (1973), and NATO operations from the air against air bases during
the Deny Flight / Deliberate Force (1992-1995) and Allied Force (1999) operations. The
article also makes a preliminary assessment of the aerial defence of air bases during the
ongoing conflict in Syria.
Considerations for patient selection: Prepectoral versus subpectoral implant-based breast reconstruction
Authors: Yang Jun Young , Kim Chan Woo , Lee Jang Won , Kim Seung Ki , Lee Seung Ah , Hwang Euna
Published: November 2019

Background In recent years, breast implants have been frequently placed in the subcutaneous pocket, in the so-called prepectoral approach. We report our technique of prepectoral implant-based breast reconstruction (IBR), as well as its surgical and aesthetic outcomes, in comparison with subpectoral IBR. We also discuss relevant considerations and pitfalls in prepectoral IBR and suggest an algorithm for the selection of patients for IBR based on our experiences.

Methods We performed 79 immediate breast reconstructions with a breast implant and an acellular dermal matrix (ADM) sling, of which 47 were subpectoral IBRs and 32 were prepectoral IBRs. Two-stage IBR was performed in 36 cases (20 subpectoral, 16 prepectoral), and direct-to-implant IBR in 43 cases (27 prepectoral, 16 subpectoral). The ADM sling supplemented the inferolateral side of the breast prosthesis in the subpectoral group and covered the entire anterior surface of the breast prosthesis in the prepectoral group.

Results The postoperative pain score was much lower in the prepectoral group than in the subpectoral group (1.78 vs. 7.17). The incidence of seroma was higher in the prepectoral group (31.3% vs. 6.4%). Other postoperative complications, such as surgical site infection, flap necrosis, implant failure, and wound dehiscence, occurred at similar rates in both groups. Animation deformities developed in 8.5% of patients in the subpectoral group and rippling deformities were more common in the prepectoral group (21.9% vs. 12.8%).

Conclusions The indications for prepectoral IBR include moderately-sized breasts with a thick well-vascularized mastectomy flap and concomitant bilateral breast reconstruction with prophylactic mastectomy.

Authors: Bayram Yalcin , Sezgic Melihcan , Karakol Percin , Bozkurt Mehmet , Filinte Gaye Taylan
Published: November 2019

Autologous fat injection was first described roughly a century ago and has been used in surgery ever since. In addition to its use in many surgical fields, it is also frequently used for both aesthetic and reconstructive purposes in breast surgery. Since the application of fat grafting in breast surgery has steadily increased, studies investigating its reliability have simultaneously become increasingly common. Previous studies have reported that the use of fat grafting in breast surgery is reliable, but some pending questions remain about its routine use. In order to use fat grafts successfully in breast surgery, it is necessary to be familiar with the structure and content of adipose tissue, the efficacy of adipose stem cell-enriched fat grafts, the oncological safety of fat grafts, and the problems that may occur in the radiological follow-up of patients who undergo fat grafting procedures. In this literature review, we aim to discuss the use of fat grafts in breast surgery by investigating these common problems.
Free flap thrombosis in patients with hypercoagulability: A systematic review
Authors: Biben Johannes Albert , Atmodiwirjo Parintosa
Published: November 2019

Background Even with satisfactory anastomosis technique and adequate experience of the surgeon, flap loss due to thrombosis can still occur due to the patient’s underlying condition. Patients with hypercoagulability due to etiologies such as malignancy, hereditary conditions, and acquired thrombophilia are among those who could benefit from free flap procedures. This review aimed to evaluate the risk of free flap thrombosis in patients with hypercoagulability and to identify the most effective thromboprophylaxis regimen.

Methods This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. The PubMed, Embase, and Cochrane Library databases were explored. Types of free flaps, types of hypercoagulable states, thrombosis prevention protocols, thrombosis complication rates, and flap vitality outcomes were reviewed. Samples from the included studies were pooled to calculate the relative risk of free flap thrombosis complications in patients with hypercoagulability compared to those without hypercoagulability.

Results In total, 885 articles underwent title, abstract, and full-text screening. Six articles met the inclusion criteria. The etiologies of hypercoagulability varied. The overall incidence of thrombosis and flap loss in hypercoagulable patients was 13% and 10.3%, respectively. The thrombosis risk was two times higher in hypercoagulable patients (P=0.074) than in controls. Thromboprophylaxis regimens were variable. Heparin was the most commonly used regimen.

Conclusions Hypercoagulability did not significantly increase the risk of free flap thrombosis. The most effective thromboprophylaxis regimen could not be determined due to variation in the regimens. Further well-designed studies should be conducted to confirm this finding.

Published: November 2019

Background There are various reconstructive options for nail bed defects. However, it is challenging not to leave a deformity. In this study, we investigated differences in outcomes depending on the reconstruction method, attempted to determine which method was better, and analyzed other factors that may affect outcomes.

Methods The long-term outcomes of nail bed reconstruction were reviewed retrospectively. We performed three types of reconstruction depending on the defect type: composite grafts of severed segments, nail bed grafts from the big toe, and two-stage surgery (flap coverage first, followed by a nail bed graft). Subsequent nail growth was evaluated during follow-up, and each outcome was graded based on Zook’s criteria. The reconstruction methods were statistically analyzed. Other factors that could contribute to the outcomes, including age, the timing of surgery, germinal matrix involvement, defect size, and the presence of bone injuries, were also compared.

Results Twenty-one patients (22 digits) who underwent nail bed reconstruction were evaluated. The type of reconstruction method did not show a significant relationship with the outcomes. However, patients who sustained injuries in the germinal matrix and patients with a defect larger than half the size of the nail bed had significantly worse outcomes than the comparison groups.

Conclusions The results suggest that no operative method was superior to another in terms of the outcomes of nail bed reconstruction. Nevertheless, involvement of the germinal matrix and defect size affected the outcomes.

Aim. The search of adaptive response peculiarities to adverse environmental factors is an important condition of development of varietal technologies and control of adaptive potential of winter wheat varieties. Methods. The studies were carried out in accordance with the field test methodology. The wheat varieties of different types of growing, different genetic and ecological origins were studied. Results. In our studies, plasticity index (bi) of most winter wheat varieties was close to one and higher under various growing conditions. The yield advantage of a number of varieties was mainly in favourable weather conditions, and in unfavourable conditions yields were low. Varieties that are more resistant to stressful conditions (Askaniis`ka, Kuialnyk, Klarisa, Driada) were characterised by relatively low response to changes of growing conditions, their regression factor was less than one and kept reducing, their resistance to unfavourable conditions were increased. Conclusions. If severe stress limits in environmental conditions are expected, it is necessary to grow and use the winter wheat varieties with increased stability of yielding capacity in selection (Khersonska bezosta, Khersonska 99, Znakhidka odes`ka, Askaniis`ka, Klarisa (facultative). Keywords: winter wheat, plasticity, stability, yielding capacity.

Published: November 2019

Aim. Evaluation of the new gametocidal agents effect on pollen sterility and viability of female gamethophyte in sunflower was the main goal ofthe investigation. Methods. Sunflower florets were treated with nine newly synthesided in the Institute of Bioorganic Chemistry and Petrochemistry of NAS of Ukraine chemicals in concentrations ranged from 1.0 ml/l to 15.0 ml/l of stock solutions. Gibberellic acid (50 mg/l) was used as a control. The gametocidal effect on the pollen sterility was determined using seed-set after gametocide treatment and controlled self-pollination compared to untreated florets. Influence of gameticides on the female gametophyte viability was evaluated as seed-set after free cross-pollination. Results. It was revealed that DGK-2 and DGK-3 have a high gametocidal activity even at the lowest dose – 1 ml/l. DSK-10 appeared to be the most effective one at a dose of 5 ml/l. This treatment allowed us to achieve near-complete male sterility. Negative effect of gametocides on the female gametophyte was enhanced with increase in their concentrations. However, new gametocides had less negative effect compared to gibberellin in certain experimental variants. Conclusions. DGK-2, DGK-3 and DSK-10 are promising for further investigations on the chemical demasculation in sunflower for further hybridization on the fertile basis without mechanical anther removal.

Keywords: sunflower, (Helianthus annuus L.), induced pollen sterility, gamitocidal agents, gibberellin, seed-set.

Physiological and biochemical analysis of transgenic wheat plants of seed generation T2 with heterologous ornithine-δ-aminotransferase gene
Authors: Dubrovna O. V. , Slivka L. V. , Kulesh S. S.
Published: November 2019

Aim. To carry out physiological and biochemical analysis of genetically modified plants of bread wheat of seed generation T2 with the heterologous ornithine-Δ-aminotransferase gene. Methods. Biochemical determination of free L-proline content and ornithine-Δ-aminotransferase enzyme activity; physiological examination of plant growth in in vitro and in vivo conditions. Results. It was shown that transgenic plants did not differ from the controls under optimal conditions of cultivation. It was determined that transgenic plants under the conditions of osmotic stress are characterized by faster growth in comparison with control genotypes. It was found that T2 plants differed in the increased activity of the ornithine-Δ-aminotransferase enzyme, which is manifested when the norm-stress-norm conditions change. It was found that the introduction of a genetic construct that increases the expression of the oat gene does not lead to a significant change in the level of free L-proline in the leaves of plants, either in normal, or in terms of osmotic stress. Conclusions. Changes in the metabolism of transgenic plants allow them to better adapt to adverse conditions. They have better adaptive plasticity, since the yield of most of the transformed lines was significantly higher, compared to non-transformed plants that were under groundwater deficit.

Reproductive ability of common winter wheat plants under drought
Authors: Zhuk O. I.
Published: November 2019

Aim. The goal of this work was to study the effect of soil drought on the reproductive ability of common winter wheat plants (Triticum aestivum L.). Methods. Wheat plants of cultivars Yednist and Zbruch were grown under optimal nutrition and well-watered conditions to the earing-flowering phase, after that the experimental plants were transferred to drought regime for 10 days, after that the optimal water supply was restored to the end of vegetation. During the experiment, the stem length and the leaf area were measured. Ripened plants were analyzed according to the structure of the yield. Results. It is established that the effect of drought in the critical phase of ontogenesis the earing-flowering led to the decreasing the stem length, the leaf area, the mass of the ear and grains, number of grains more in Zbruch cultivar than in Yednist cultivar. In Zbruch cultivar under drought the number of productive stems per plant decreased. Conclusions. Water deficiency in the soil in the critical phase of earing-flowering led to a decrease in the reproductive ability of winter wheat plants due to the inhibition of growth of stem, reduction of the leaf area, the grain number and the mass of ear and grains. Keywords: Triticum aestivum L., stem, ear, productivity, drought.

Aim. The aim of this study was to isolate and propagate mutants at gliadin loci developed on the basis of the common wheat cultivar Bezostaya 1. Methods. We searched for spontaneous and gamma-irradiation induced mutations at gliadin loci among the progeny of F1 and F2 plants from crosses between near-isogenic lines by gliadin loci on the basis of the cultivar Bezostaya 1, including lines with the wheat-rye 1BL.1RS translocation. To identify mutations, we performed acid polyacrylamide gel electrophoresis and SDS-electrophoresis of storage proteins. Results. On the basis of the common wheat cultivar Bezostaya 1, five mutants (six mutations) at gliadin loci were isolated and propagated, four of which were described for the first time. Three mutations occurred at the Gli-R1 locus involved in the wheat-rye 1BL.1RS translocation (the loss of secalins, intensification of a secalin component, and increased mobility of a secalin component). Two mutations were identified in the allele Gli-B1b, one caused the null-allele at the Gli-A2 locus. Conclusions. The material of mutants is of importance for studying the role of certain groups of storage proteins and their components in quality determination, as well as mechanisms of regulation of storage protein synthesis.
