Fiber reinforced composite bridge as a replacement for missing upper permanent lateral incisor – a case report
Authors: Todorović Ana , Popović Danica , Djordjević Igor , Lazić Vojkan 
Published: April 2019

Abstract
Hypodontia of upper lateral incisors is significant aesthetic problem in young people. Ideal solution to this problem would be an implant placement, but there is a problem of unfinished growth and development. It is therefore necessary to have a temporary solution in order to maintain normal stomatognathic system functions and solve aesthetic problems until the final restoration is placed.
The aim of this study was to show the possibility of treating hypodontia of permanent upper lateral incisors by creating adhesive bridge in one visit.
A 15-year-old patient was referred to the Department for Prosthodontics, School of Dental Medicine in Belgrade with hypodontia of permanent upper lateral incisors. The patient had braces until 14 years of age after which she was rehabilitated with partial denture that was neither aesthetically nor functionally acceptable solution for her and significantly affected her emotional security. The adhesive bridge was made using GC composite fibers and a set of GC composite materials for the purpose of temporary replacement of missing teeth. This treatment provided good functional and aesthetic results. The space for the placement of two endosseous implants is preserved and a period of adaptation positively influenced the patient’s social development in sensitive adolescent age.
Peripheral giant cell granuloma – case report
Authors: Tomić Slavoljub , Davidović Bojana 
Published: April 2019

Abstract
Peripheral giant cell granuloma (PGCG) or “Epulis gigantocelularis” is the most common oral lesion that originates from giant cells. It typically manifests in the form of soft tissue tumor purple-red or red-watery color consisting of multinuclear giant cells in the mononuclear stroma and extravascular erythrocytes. This lesion is not considered true neoplasm, rather reactive lesion stimulated by local irritation and trauma. However, the cause is not known with certainty.
This paper presents a 13-year-old boy with a large lesion in the region of right maxillary canine that was retained in jaw despite favorable vertical position and available space to accommodate in the dental arch. The lesion was completely removed under local anesthesia and histopathological findings confirmed the diagnosis of PGCG. Postoperative period went without complications. After four months additional surgical procedure was needed due to the recurrence, which after tooth naturally erupted and positioned in the dental arch.

Summary
There is growing need for synthetic tissue replacement materials designed in a way that mimic complex structure of tissues and organs. Among various methods for fabrication of implants (scaffolds), 3D printing is very powerful technique because it enables creation of scaffolds with complex internal structures and high resolution, based on medical data sets. This method allows fabrication of scaffolds with desired macro- and micro-porosity and fully interconnected pore network. Rapid development of 3D printing technologies has enabled various applications from the creation of anatomical training models for complex surgical procedures to the printing of tissue engineering constructs. The aim of current investigations was to develop compatible printers and materials (bioinks) to obtain biomimetic scaffolds, which allow printing of living cells without significant loss of cell viability. The advanced level of such printing assumes “in situ” printing, i.e. printing cells and biomaterials directly onto or in a patient that will reduce recovery time.
Integration of function, aesthetics and patients’ personal preferences in the prosthetic treatment planning
Authors: Iliev Georgi 
Published: April 2019

Abstract
Introduction Optimal aesthetic results require suitable smile design that fulfils patient’s expectations. Psychological importance of teeth appearance is clear and often discussed in relation to the success of prosthetic treatment. The objective of this article was to present methodology for creating customized smile design using the Visagismile concept and evaluate aesthetic satisfaction with prosthetic treatment.
Case report A 52-year-old female patient required complete esthetical dental mouth reconstruction. Digital planning software (Visagismile) provided dentists and technicians a 2D preview of the final design that relates facial perception and personality of the patient. The latest innovation of used software in addition to documents that dentists send for the Visagismile application is that they need to send an intraoral 3D scan of the patients mouth (with any scanner) and define the length and position of incisal edges of the central incisors. This information as a STL file is sent to new Visagismile/REBEL center that is actually a digital lab, that converts 2D designs created by the Visagismile concept into 3D and create a digital wax up immediately.
Conclusions Visagismile concept supports both dentist and patient in deciding the aesthetics of the prosthetic restoration. The total coefficient of the assessment of patients for the final aesthetic result was highly satisfactory. Using the proposed methodology, a smile design corresponding to individual facial features, temperament and personal preferences of the patient can be reproduced.
Über die Trägheit der Wände zwischen Weißschen Bezirken
Authors: Döring Werner 
Published: April 2019

Abstract
Da das magnetische Moment der Elektronen mit einem mechanischen Drehimpuls verknüpft ist, muß die Verteilung der Magnetisierungsvektoren in einer bewegten Wand zwischen zwei Weißschen Bezirken sich von derjenigen in der gleichen Wand in Ruhe etwas unterscheiden. Der Energieinhalt der bewegten Wand ist deshalb etwas größer als der der ruhenden Wand. Der Unterschied ist proportional dem Quadrat der Geschwindigkeit, also gerade so, als ob die Wand eine träge Masse besäße. Diese Er-scheinung ist von Einfluß auf die Dispersion der ferromagnetischen Permeabilität. I n einem ferromagnetischen Kristall mit kleinen

Published: April 2019

En el presente trabajo estudiamos el grado de tolerancia a metales pesados de hongos y bacterias aisladas de suelos con y sin rizósfera, con el propósito de conocer su potencial para aplicaciones en biorremediación. Las muestras procedían del pasivo minero de Santa Rosa de Jangas. Los hongos y bacterias aislados fueron identificados taxonómicamente mediante el análisis de la región ITS y 16S ADNr, respectivamente. El índice de tolerancia a metales pesados se calculó usando medio salino suplementado con 1 mM a plomo (II), cobre (II), niquel (II) o zinc (II), y 0.1 mM a plata (I), cromo (VI) o cadmio (II). En total se aislaron 23 hongos y 18 bacterias. Las cepas de hongos con mejores índices de tolerancia fueron: Fusarium temperatum CTLM05 (Pb+2), F. temperatum CTLM08 (Zn+2), F. oxysporum CTLM18 (Ni+2 y Cd+2), F. oxysporum CTLM12 (Ag+1), F. inflexumCTLM22 (Cu+2) y Penicillium vanluykii CTLM11 (Cr+6). Las cepas de bacterias con mayores índices de tolerancia fueron Bacillus licheniformis SSR18 (Cd+2, Ni+2 y Zn+2), B. subtilis SSR3 (Pb+2), Serratia sp. SSR15 (Cu+2), Serratia sp. SSR13 (Ag+1) y B. cereus SSR01 (Cr+6). También se encontró que los hongos mostraron mejores índices de tolerancia que las bacterias. Finalmente, los suelos del pasivo ambiental minero de Santa Rosa de Jangas poseen una microflora interesante, probablemente con mecanismos para su adaptación, crecimiento y desarrollo sobre metales pesados y pueden ser de utilidad para el desarrollo de procesos biotecnológicos y biorremediación.

Assessment of probiotic effects on colorectal surgery complications: A double blinded, randomized clinical trial
Authors: Kakaei Farzad , Shahrasbi Mohammadreza , Asvadi Kermani Touraj , Taheri Sahar , Tarvirdizade Kowsar 
Published: April 2019

Background: Probiotics are living bacteria, which can be used as a food supplement to produce inhibitory agents and compete with pathogens in the guts. Nowadays, because of the easy accessibility and misuse of antibiotics, probiotic usage is increasing. The goal of our study is to assess the effects of probiotics on colorectal surgery complications.
Methods: The enrolled cases were selected from colorectal surgery candidate patients, who referred to Sina and Imam Reza Hospitals of Tabriz University from April of 2016 to April of 2017. They were divided into two groups of study and control. For the study group, 7 days before surgery, one capsule of probiotics (Familact) was administrated every night, while the control group was given capsules of placebo.
Results: Although the infective complications, mortality ratio and duration of hospitalization in the study group were lower than the control group, these differences were not statistically significant. Discussion: Our study confirmed that preoperative probiotic consumption in colorectal surgery had not affected complications or mortality of surgery and this finding is in disagreement with some previous studies. Perhaps, other strains of bacteria or different dosage, duration and rout of administration can have positive effects on these complications.
Conclusion: This study showed that there was no correlation between probiotic consumption preoperatively and decreased complications or mortality after colorectal surgery.

Published: April 2019

Background: Correction of a crooked or deviated nose is a major challenge for rhinoplasty surgeons. In the present study we proposed to compare the aesthetic and functional results of unilateral grafting using spreader grafts on the convex side of the nasal deviation with those used on the concave side.
Methods: In this study, the technique and aesthetic and functional outcomes of the correction of crooked noses with spreader graft placement at either convex or concave side of the nasal deviation are presented.
Results: Unilateral spreader graft was used in 66 patients with C-type deviated nose. At the discretion of the rhinoplasty surgeon, the spreader graft was placed in the convex side of the nasal deviation in 33 patients (group A) and in the concave side of the nasal deviation in the remaining 33 patients (group B). During an average following-up period of 18 months (ranged from 8 to 36 months), there were no complications, infection, or graft extrusions. Functional evaluation was performed using a visual analog scale before and 4 months after surgery. Patients were asked to score their nasal breathing on a scale from 0 to 10. In group A (convex group), the mean preoperative score was 6.32+/-1.02 (ranging from 2 to 8), and the mean postoperative score was 2.03+/-1.01 (ranging from 0 to 4). In group B (concave group), the mean preoperative score was 6.76+/-1.10 (ranging from 2 to 8), and the mean postoperative score was 3.67+/-1.80 (ranging from 2 to 7). Patients with spreader graft at the convex side showed higher increase in angle measurements as compared to the patients with spreader graft in the concave side. Moreover, patients with spreader graft at the convex side were more likely to have excellent or good surgical outcomes (according to the degree of correction in the angle of deviation) as compared to patients with spreader graft in the concave side.
Conclusion: The use of the spreader graft is a safe and effective method for correction of crooked noses. We showed that speeder graft at the convex side of C-type nose deformity provided better aesthetic and functional results as compared to the placement of the speeder graft in the concave side of the nasal deformity.

Technique of monitoring of the level of development of cycle transport infrastructure perceived by citizens in Moscow
Authors: Zavyalov D. V. , Saginova O. V. , Zavyalova N. B. 
Published: April 2019

Purpose: of the article is a proposal for a methodology for assessing the level of development of Cycling infrastructure in Moscow and a conceptual model of a system for monitoring transport infrastructure.Methods: to achieve this goal, the authors analyzed foreign and domestic experience in the development of the cycle transport infrastructure and methods for assessing its level of development. In preparing the article, the results of content analysis of scientific publications and research reports of Russian and foreign scientists and practitioners who are experts in the field of increasing the mobility of the urban population in megalopolises, in field studies and observations are used. The study is based on the marketing approach, which takes into account the objective indicators of the development of Cycling and the perceived level of development of Cycling infrastructure.Results: increasing the mobility of Moscow residents using environmental modes of transport is an important strategic task of the metropolis. For its successful solution, it is necessary to create a monitoring system that provides control over the achievement of the objectives of the development of Cycle transport infrastructure. The article presents the results of the development of a system for monitoring the level of development of Cycling infrastructure. A system of indicators, which is the basis of the monitoring system, has been developed, and the methodology has been tested. The test results can be defined as initial for the next monitoring Cycle.Conclusions and Relevance: the analysis of international and Russian experience in the development of transport infrastructure of megacities showed a significant interest in the integration of Cycling in multimodal travel of passengers. Active use of Cycling is associated with a change in the transport behavior of residents of the metropolis. This is largely determined by the level of development of the Cycle transport infrastructure. The Cycle infrastructure must meet the demands of citizens, the safety of cycling around the city, as well as other characteristics that provide the attractiveness and convenience of using cycles in the city. The paper proposes a system for monitoring the level of development of Cycling infrastructure. The monitoring is based on the assessment of hierarchical indicators grouped by management objectives. The indicators recommended for use in the monitoring system correspond to the principles of accessibility of information, reflect both subjective and objective factors that characterize the development of Cycling infrastructure, allow to identify local problems of Cycling infrastructure in all areas of Cycling. Testing of the monitoring system confirmed the possibility of its use to support management decision-making on improving the city’s transport system.
