Pre-clinical assessments of bone substitute materials are frequent in the literature, but research papers about the clinical situation of bone graft use and consumer market acceptance are rare. The aim of this study was to evaluate the dental use of bone grafts according to the perception of dentists in the city of Sobral, Brazil. We interviewed 183 professionals and analyzed their professional data, knowledge of the subject, specific use, and opinions on cost-effectiveness and biosafety. Most of the respondents had 10 years’ or less experience in the profession, and lacked specialization though they had been familiar with the subject since they graduated. The most frequently mentioned compositions were ceramics, followed by composites. Only a quarter of the respondents had performed bone grafts, generally with up to 50 cases, with the most frequent applications being using simultaneously with a dental implant, fresh dental sockets and maxillary sinus lifting. Autogenous and xenogeneic grafts were more frequent than alloplastic and allogeneic; ceramics were the most frequently used composition, and the association of bone graft with membrane was more frequent than bone graft alone or associated with autologous fibrin. Professional and patient satisfaction was high, cost was considered moderate, and differences were found regarding patient participation in the choice and country of origin of the product. Bone grafts were used more often in the private than public service. Dentists stated that they follow the instructions. Inflammatory or infectious complications were found to be related to the frequency of the procedure performed and safety regarding the origin. Opinions were favorable regarding the use of grafts derived from animals and unfavorable to grafts derived from cadavers. Very few respondents were registered in human bone tissue banks. The good level of acceptance for dental use of bone grafts in a Brazilian inland city provides a promising scenario for the development of the sector.

Abstract The article studies the existence experience of historical cities as centers of tourism development as in the case of Elabuga. The city of Elabuga is among the historical cities of Russia. The major role in the development of the city as a tourist center is played by the Elabuga State Historical-Architectural and Art Museum-Reserve. The object of the research in the article is Elabuga as a medium-size historical city. The subject of the research is the activity of the museum-reserve which contributes to the preservation and development of the historical look of Elabuga and increases its attractiveness to tourists. The tourism attractiveness of Elabuga is obtained primarily through the presence of the perfectly preserved historical center of the city with the blocks of integral buildings of the 19th century. The Elabuga State Historical-Architectural and Art Museum-Reserve, which emerged in 1989, is currently an object of historical and cultural heritage of federal importance. Museum-reserves with their significant territories and rich historical, cultural and natural heritage have unique resources for the implementation of large partnership projects. Such projects are not only aimed at attracting a wide range of tourists, but also stimulate interest in the reserve from the business elite, municipal and regional authorities. The most famous example is the Spasskaya Fair which revived in 2008 in Elabuga. It was held in the city since the second half of the 19th century, and was widely known throughout Russia. The process of the revival and successful development of the fair can be viewed as the creation of a special tourist event contributing to the formation of new and currently important tourism products.

The image of the city is a spatio-temporal continuum in which everything is interconnected, it exists as a single monolith expressing itself in the general atmosphere. The visual image of the city may contain two planes of meanings: culturally ratified and universally valid, expressed by cultural codes, and also significant only to those who are viewing the image. Therefore, the content of the visual image depends on who the subject of perception is, what he pays attention to and in what situation the process of perception of the image occurs.

The subject of the article is an analysis of the three aspects of depicting urban space of Eastern Ukraine, focusing specifi cally on the Donbass region and the city of Kharkov as depicted in the novels Voroshilovgrad (2010) and Mesopotamia (2014) by Serhiy Zhadan. The urban space of Eastern Ukraine overlaps with the most important values that shape a person’s personality and aff ect her or his self-identifi cation. The city space is also a “place of memory” and experiences of generations that infl uence current events. In addition to the historical and axiological dimension, the imaginative aspect of space is also important. This approach is used by the author to describe the urban space as a functioning imagination or stereotypes associated with it as opposed to its realistic depiction.

AbstractThin mechanically stable Ti-cages have been developed for the in-vivo application as X-ray and histology markers for the optimized evaluation of pre-clinical performance of bone graft materials. A metallic frame defines the region of interest during histological investigations and supports the identification of the defect site. This standardization of the procedure enhances the quality of pre-clinical experiments. Different models of thin metallic frameworks were designed and produced out of titanium by additive manufacturing (Selective Laser Melting). The productibility, the mechanical stability, the handling and suitability of several frame geometries were tested during surgery in artificial and in ex-vivo bone before a series of cages was preclinically investigated in the female Göttingen minipigs model. With our novel approach, a flexible process was established that can be adapted to the requirements of any specific animal model and bone graft testing.

Objective This study was performed to evaluate the surgical indications, clinical efficacy, and preliminary experiences of nonstructural bone grafts for lumbar tuberculosis (TB). Methods Thirty-four patients with lumbar TB who were treated with nonstructural bone grafts were retrospectively assessed. The operative time, operative blood loss, hospital stay, bone graft fusion time, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, visual analog scale (VAS) score, Oswestry Disability Index (ODI), American Spinal Injury Association (ASIA) impairment grade, and Cobb angle were recorded and analyzed. Results The mean operative time, operative blood loss, hospital stay, Cobb angle correction, and Cobb angle loss were 192.59 ± 42.16 minutes, 385.29 ± 251.82 mL, 14.91 ± 5.06 days, 9.02° ± 3.16°, and 5.54° ± 1.09°, respectively. During the mean follow-up of 27.53 ± 8.90 months, significant improvements were observed in the ESR, CRP concentration, VAS score, ODI, and ASIA grade. The mean bone graft fusion time was 5.15 ± 1.13 months. Three complications occurred, and all were cured after active treatment. Conclusions Nonstructural bone grafts may achieve satisfactory clinical efficacy for appropriately selected patients with lumbar TB.

AbstractMineralized tissue regeneration is an important and challenging part of the field of tissue engineering and regeneration. At present, autograft harvest procedures may cause secondary trauma to patients, while bone scaffold materials lack osteogenic activity, resulting in a limited application. Loaded with osteogenic induction growth factor can improve the osteoinductive performance of bone graft, but the explosive release of growth factor may also cause side effects. In this study, we innovatively used platelet-rich fibrin (PRF)-modified bone scaffolds (Bio-Oss®) to replace autograft, and used cytokine (BMP-2) to enhance osteogenesis. Encouragingly, this mixture, which we named “Autograft Mimic (AGM)”, has multiple functions and advantages. (1) The fiber network provided by PRF binds the entire bone scaffold together, thereby shaping the bone grafts and maintaining the space of the defect area. (2) The sustained release of BMP-2 from bone graft promoted bone regeneration continuously. (3) AGM recruited bone marrow mesenchymal stem cells (BMSCs) and promote their proliferation, migration, and osteogenic differentiation. Thus, AGM developed in this study can improve osteogenesis, and provide new guidance for the development of clinical bone grafts.

Physical Education is one of the subjects that arouses the most interest in children. The aim of this study is to find out the opinion that primary school students have about the Physical Education class. Drawings from a sample of 62 students from an educational centre in the city of Jaén, aged between six and eight years old, were analysed. The results show that the larger size of the drawings corresponds to the aspects that are to be emphasised. This subject is carried out regularly in the sports pavilion of the centre, making frequent use of materials such as sticks, hoops or balls. Cheerful colours are used, reflecting their enthusiasm for the subject. The smiling facial expression represents the schoolchildren’s interest in the subject. The most popular games or sports are basketball and pichi, both of them collective.

The construction date of the ‘Servian’ wall and its layout in the riverside area between the Aventine and the Capitol are the two main questions addressed in this article. The interlocking topographical problems were addressed in 1988 by Filippo Coarelli, whose interpretation has become the generally accepted orthodoxy. But not all the difficulties have been solved, and with Coarelli's recent return to the subject a fresh examination of the evidence may be helpful. Careful attention is given here to stories of early Rome that involve the walls and gates, as reported in Livy, Dionysius and Plutarch; they are not, of course, taken as authentic evidence for the time of the alleged events, but as indicating what was taken for granted when the stories were first composed. New suggestions are made about a revision of the line of the city wall in 212 BC and the consequent restructuring of two important gates, the Porta Carmentalis and the Porta Trigemina; the mysterious ‘Porta Triumphalis’ is discussed separately in an appendix.

Ruth, a tale of human kindness and just dealing far beyond the norm, contains elements that for centuries have been the subject of debate. With a sprightly translation and a commentary rich in informed speculation, Professor Campbell considers the questions of layman and scholar alike. Finding no overt mighty acts, the layman asks, “Why was Ruth included in the Bible at all? Where is God?” Professor Campbell shows that God is not only present throughout but is indeed the moving force behind all the developments of the story. Naomi, Ruth, and Boaz each act as God to each other, by taking extraordinary responsibility and performing extraordinary acts of kindness. And it is God who is responsible for the series of coincidences on which the plot hinges. The scholar’s questions deal with such matters as purpose, date, and genre. Professor Campbell’s research into ancient customs and linguistics suggests to him that Ruth is a historical novelette, entertaining and instructive, composed not long after the reign of King David, during the time of Solomon or within the subsequent century. Professor Campbell demonstrates the storyteller’s skill with sensitive analysis of form, pacing, and wordplay. By delving into word origins and nuances he shows how convincingly the characters are developed. One instance: Naomi and Boaz use obsolescent language, emphasizing the generation gap between them and Ruth. In addition, the illustrations help the reader understand unfamiliar elements of the story—the setting, the agricultural seasons and harvesting, the clothing of the times, the city gate where elders and interested villagers gather to make sure that all is done in a just and godly way.
