The paper presents a historiographic context helpful in the current investigations of the cultural contacts between the societies of the east and west of Europe in the borderland of Podolia and moldova in the late Eneolithic and the prologue of the Bronze age . The focus is on the state of research (chiefly taxonomic and topogenetic) into the sequence of taxa in the age of early ‘barrow-building’, identified in the funerary rituals of societies settling the forest-steppe of the north- western Black Sea Coast in the 4th/3rd-2nd millennium BC .

The paper discusses the taxonomy and autogenesis of the cycle of early ‘barrow cultures’ developed by the local communities of the middle Dniester Area or, in a broader comparative context, the north-western Black Sea Coast, in the 4th/3rd-2nd millennium BC . The purpose of the study is to conduct an analytical and conceptual entry point to the research questions of the dniester Contact area, specifically the contacts between autochthonous ‘late Eneolithic’ communities (Yamnaya, Catacomb and Babyno cultures) and incoming communities from the Baltic basin . The discussion of these cultures continues in other papers presented in this volume of Baltic-Pontic Studies.

Aim: To investigate the healing process following use of collagen sponges in the dental socket after extraction. Wound complications during the study were also evaluated. Methods: 32 cats were included in this study. IV administration of the combination of diazepam (0.22 mg/kg) and ketamine (10 mg/kg) was used to induce general anesthesia. Surgical extraction of both 3rd mandibular premolars was performed. The open dental sockets were divided in two groups. In Group A, the open dental socket on the left side was closed using 4-0 Monocryl in simple interrupted pattern. In Group B, the right dental socket was filled with lyophilized hydrolyzed collagen and the buccal and lingual flaps were sutured using 4-0 Monocryl and simple interrupted pattern. Meloxicam (0.2 mg/kg) was used to manage the post-extraction pain in all cats. Ampicilline 20 mg/kg was used as prophylaxis. The wounds were observed during the study to evaluate any signs of inflammation or dehiscence. Radiographs were taken to compare healing of the socket 3 weeks after the procedure. A 1 mm biopsy punch sample was taken from sockets in all cats for comparison of the healing in both groups. Results: Hemorrhage occurred only in the sockets of Group A. Remission of radiolucent area occurred in both groups. Mean score of inflammation was lower and mean scores of fibrotic reaction and fibroplasia were higher in Group B (p<0.05). Conclusions: Use of hemosponge in alveolar socket may accelerate fibroplasia and formation of the connective tissue and reduce inflammation after tooth extraction. Therefore, post-extraction use of the hemostatic agent in the dental socket is recommended.

Agroforestry is considered nowadays as a sustainable form of land management that is being promoted by different global institutions like FAO and its Global Alliance Smart Climate Agriculture to mitigate and adaptate to Climate change. The European Commission through the protection of landscape features, greening and Rural Development Programs is promoting the essential presence of woody vegetation across Europe, but in a way that is difficult to recognize by farmers. AGROFE and AGFORWARD projects are both demonstrating the important value of Agroforestry at European level, which together with EURAF are pushing European Commission to include measures enhancing Agroforestry. However, there is a need of a European Agroforestry Strategy that recognizes the drawbacks of Agroforestry to be implemented at European level. This strategy should include the main mechanisms to show farmers how to implement it and at the same time to get funded for the important ecosystem services that they provide when implementing agroforestry. AGFORWARD project has identified the main agroforestry practices in Europe, highlighting silvopasture, but showing the importance that others forms of agroforestry have to play like homegardens with multipurpose trees, or the adequate improvement of fallow lands where woody vegetation can enhance the levels of organic matter in the soil if adequately managed. AGFORWARD also shows the lack of information of the real implementation of agroforestry practices like forest farming, in spite of the important productive and ecosystem benefits it provides. EURAF through the participation in the different civil dialogue groups (CAP, Direct Payments and Greening, Forestry and Cork, Organic Farming, Arable, Environment and Climate Change and Rural Development) has included and promoted agroforestry within the European Agenda. The role of Agroforestry has been also enhanced in the Groups of experts of European Structural and Investments funds and as part of the European Network for Rural Development and its derived groups: innovation, evaluation and CLLD/LEADER. EURAF is pleased to announce that Agroforestry will be discussed as part of a focus group of the European Innovation Partnership, so, apply and join the group. This book represents the lastest findings on agroforestry in Europe, integrating the participation of researchers but also policy makers and farmers and farmers' associations. It was a pleasure for EURAF to integrate all this needed knowledge to be disseminated at European levels. On behalf of EURAF, I wish all of you a successful meeting and invite you to strengthen agroforestry within the different European Union countries when you go back home.

Introduction: Arrhythmogenic right ventricular dysplasia (ARVD), a cardiomyopathy characterized by fibrofatty degeneration of the myocardium with progressive dysfunction, electrical instability, and sudden death, occurs in approximately 1 in 5000 people in the United States. Case Presentation: We present a nine-year-old girl complaining of dyspnea, easy fatigability and skin lesions. She had a history of an occasional epistaxis and weakness since 20 days before her admission, accompanied by the symptoms and signs of common cold, specially cough, during the last two days. Conclusions: This case does confirm that dilated cardiomyopathy’s spectrum is wider than ever known and that like what happened at the congress of Boston in 2006, a more comprehensive approach to its genetic types needs to be done.

The perceptions about school play a central role in behavior, performance and learning outcomes. There is evidence that an improvement in emotional skills is associated with a higher school success. The aim of this paper is to know the relationship between internalizing and externalizing behaviors, emotional skills and academic success of students of the 3rd cycle of basic education. In order to promote students social and emotional skills, a pilot study in a School Grouping of the central region (Portugal) was carried out. It was made a diagnosis of disruptive behavior (ASEBA) and identified 6 children aged between 12 and 14 years old and followed by 3 focus groups with students, parents, and teachers, respectively. Six students mostly male were identified, with the predominance of externalizing behaviors and academic failure. They don’t like school and have no motivation for learning. The relationship between parents and teachers is conflictive. All parents have the utmost concern academic success and teachers perceived good practices, but without success. This program is seen in a perspective of empowerment of the educational agents to manage various environments and relationships. The results point to the importance of the systemic intervention program on the improvement of the social and emotional competences and academic achievement.

Problem Statement: The perceptions about school, play a central role in behavior, performance and results. There is evidence that an improvement in emotional skills is associated with a higher success. Research Questions: What is the relationship between internalizing and externalizing behaviors, emotional skills and academic success in the 3rd cycle of basic education? Purpose of Study: To promote social and emotional skills of students, in the 3rd cycle of basic education. Research Methods: A pilot study with groups of 7th year at a school central Portugal. Made diagnosis of disruptive behavior (ASEBA) was identified 6 children aged 12 0s and 14 and followed by 3 focus groups with students, parents, and teachers respectively. Findings: 6 students mostly male were identified (70 %), with the predominance of externalizing behaviors and academic failure. Not like school (80%) and have no motivation for learning. The relationship between parents and teachers is conflituoso. 100 % of parents have the utmost concern academic success and teachers perceptional good practices, but without success. Conclusions: This program is seen in a perspective of empowerment of the various educational agents to manage various environments and relationships. The results point to the importance of the focus group in the awareness of relational problems in schools. Less adjusted change behaviors imply the involvement of all educators.

The goal of the present dissertation is to explore the urbanization process in Castabala in A.D. 1st to 3rd centuries, along with the factors affecting the urbanization of the city and the impact of Romanization on this process, by making use of the buildings that are proven or assumed to date back to this period. A further goal is to provide a general assessment of these buildings based on the finds and findings revealed by the excavations in Castabala, which first started in 2009, and use these as evidence for proposing new dating for buildings that have not been fully dated.

INTRODUCTION Endograft deployment is a well-known cause of arterial stiffness increase as well as arterial stiffness increase represent a recognized cardiovascular risk factor. A harmful effect on cardiac function induced by the endograft deployment should be investigated. Aim of this study was to evaluate the impact of endograft deployment on the arterial stiffness and cardiac geometry of patients treated for aortic aneurysm in order to detect modifications that could justify an increased cardiac mortality at follow-up. MATHERIALS AND METHODS Over a period of 3 years, patients undergoing elective EVAR for infrarenal aortic pathologies in two university centers in Emilia Romagna were examined. All patients underwent pre-operative and six-months post-operative Pulse Wave Velocity (PWV) examination using an ultrasound-based method performed by vascular surgeons together with trans-thoracic echocardiography examination in order to evaluate cardiac chambers geometry before and after the treatment. RESULTS 69 patients were enrolled. After 36 months, 36 patients (52%) completed the 6 months follow-up examination.The ultrasound-based carotid-femoral PWV measurements performed preoperatively and 6 months after the procedure revealed a significant postoperative increase of cf-PWV (11,6±3,6 m/sec vs 12,3±8 m/sec; p.value:0,037).Postoperative LVtdV (90±28,3 ml/m2 vs 99,1±29,7 ml/m2; p.value:0.031) LVtdVi (47,4±15,9 ml/m2 vs 51,9±14,9 ml/m2; p.value:0.050), IVStd (12±1,5 mm vs 12,1±1,3 mm; p.value:0,027) were significantly increased if compared with preoperative measures.Postoperative E/A (0,76±0,26 vs 0,6±0,67; p.value:0,011), E’ lateral (9,5±2,6 vs 7,9±2,6; p.value:0,024) and A’ septal (10,8±1,5 vs 8,9±2; p.value0,005) were significantly reduced if compared with preoperative measurements CONCLUSION The endovascular treatment of the abdominal aorta causes an immediate and significant increase of the aortic stiffness.This increase reflects negatively on patients’ cardiac geometry inducing left ventricle hypertrophy and mild diastolic disfunction after just 6 months from endograft’s implantation.Further investigations and long-term results are necessary to access if this negative remodeling could affect the cardiac outcome of patient treated using the endovascular approach.

Cardiac arrhythmias are one of the main causes of death worldwide. Several studies have shown that inflammation plays a key role in different cardiac diseases and Toll-like receptors (TLRs) seem to be involved in cardiac complications. In the present study, we investigated whether the activation of TLR4 induces cardiac electrical remodeling and arrhythmias, and the signaling pathway involved in these effects. Membrane potential was recorded in Wistar rat ventricle. Ca(2+) transients, as well as the L-type Ca(2+) current (ICaL) and the transient outward K(+) current (Ito), were recorded in isolated myocytes after 24 h exposure to the TLR4 agonist, lipopolysaccharide (LPS, 1 μg/ml). TLR4 stimulation in vitro promoted a cardiac electrical remodeling that leads to action potential prolongation associated with arrhythmic events, such as delayed afterdepolarization and triggered activity. After 24 h LPS incubation, Ito amplitude, as well as Kv4.3 and KChIP2 mRNA levels were reduced. The Ito decrease by LPS was prevented by inhibition of interferon regulatory factor 3 (IRF3), but not by inhibition of interleukin-1 receptor-associated kinase 4 (IRAK4) or nuclear factor kappa B (NF-κB). Extrasystolic activity was present in 25% of the cells, but apart from that, Ca(2+) transients and ICaL were not affected by LPS; however, Na(+)/Ca(2+) exchanger (NCX) activity was apparently increased. We conclude that TLR4 activation decreased Ito, which increased AP duration via a MyD88-independent, IRF3-dependent pathway. The longer action potential, associated with enhanced Ca(2+) efflux via NCX, could explain the presence of arrhythmias in the LPS group.
