Abstract Objective The aim of this research was to examine the attitudes and perceptions of dentofacial aesthetics among different age groups. Materials and Methods The sample consisted of elementary-school students from the city of Sarajevo, Bosnia and Herzegovina, and their parents. This study included 314 subjects: 157 children and 157 parents. The children’s group consisted of 85 (54.14%) males and 72 (45.85%) females, aged 9 to 15 years. Statistical Analysis Descriptive statistics were used to determine frequency distribution and percentages for all variables. A chi-squared (x 2) test was used to determine the association between variables and a p-value < 0.05 was considered significant for all the differences and associations. Results For the dentofacial appearance with no teeth irregularity or with severe teeth irregularity, an analysis of variance (ANOVA) (post-hoc tests—Tukey’s HSD) indicated that the difference is not statistically significant (p = 0.06) relative to rank matching between all three subject groups. For dentofacial appearance with mild teeth irregularity, an ANOVA (post-hoc tests—Tukey’s HSD) showed statistical difference (p = 0.07) between the teenage group of subjects relative to pre-teenage group of subjects and adult group of subjects. Conclusion Attitudes about desirable and acceptable dental aesthetics differ in younger children compared with older children and parents. Ten years old children find good function with poor aesthetics more pleasing, while 14 years old children find aesthetics with bad function as more pleasing.

Oxidative stress is a state of excess of prooxidative species relative to the antioxidant defenses (enzymatic and nonenzymatic) in a living organism. The consequence of this imbalance is damage of the major cellular macromolecules (carbohydrates, lipids, proteins, and DNA), which further leads to a gradual loss of tissue and organ function. It has been shown that oxidative stress plays an important role in the pathogenesis of many chronic diseases (cardiovascular, metabolic, and neurodegenerative diseases and cancer) and in the process of aging. Thus, many strategies to combat oxidative stress have been proposed and tested. In this context, food rich in antioxidants has received great attention. Pomegranate, berries, and walnuts have been recognized as “superfood” particularly for their cardioprotective effects. The common characteristic of these foods is the high content of ellagitannins. Since tannins are not bioavailable, they have been neglected in nutrition science and even considered antinutrients for a long time. However, this view has changed dramatically once it was recognized that ellagic acid, released from ellagitannins in the gastrointestinal system, is further metabolized by colonic microbiota to bioavailable compounds—known as urolithins. Thus, urolithins (3,4-benzocoumarin derivatives) have emerged as novel natural bioactive compounds and are now the focus of extensive investigations. So far, urolithins were shown to be powerful modulators of oxidative stress and agents with potential anti-inflammatory, antiproliferative, and antiaging properties. Furthermore, a few synthetic derivatives of urolithins were recognized as lead compounds for new drug development. Available data on urolithin synthesis, physicochemical and pharmacokinetic characteristics, biological activity, and safety will be presented in this review.

Emerging adulthood is typically defined as 18-25 years of age. It may be a particularly important time for establishing long-term health behavior patterns. The transition between adolescence and adulthood is a period of increased risk for excess weight gain, because of shifts in activity patterns as well as declines in overall-diet quality. Sugar-sweetened beverages, a great source of added sugar to the diet, contribute to energy imbalance. A small, persistent energy imbalance of 50 calories per day could result in a 5-pound weight gain over the course of one year. This study aimed to assess the nourish status in a sample of students from Faculty of Medicine of Sarajevo University and correlate it with student consumption pattern of sugar-sweetened beverages. A cross-sectional survey of 246 students was performed during May 2018, at the Sarajevo University. Verbal informed consent was obtained from all participants before completing the self-administered questionnaire that included questions on their frequency of consumption of SSBs eating habits and anthropometrics measures, weight and height. Body mass index was used to assess students nourish status. Statistical analyses were performed using the Statistical Package for Social Sciences software (IBM, version 23.0). Results were expressed as percentages and means ± standard deviations. This study showed that the majority of the students (69.26%) were of normal weight. One quarter of sample (26.83%) had BMI > 24.9. Intake of soda was more common among students with BMI ≥ 25 kg/m2 than students with BMI ≤ 24.9 kg/m2 (78.79% vs. 63.89% respectively). Among students with BMI ≤ 24.9 kg/m2, 73.33% reported drinking energy drink never compared to 42.42% students with BMI ≥ 25 kg/m2. This study gives baseline information about weight status and consumption pattern of SSBs among a sample of university students. Regulating the intake of free sugars could be used as an approach for successful body weight control.

In this paper, the influence of biological acid dough with a strain of lactic acid bacteria (Lactobacillus plantarum) on the properties of the dough and the addition of sourdough on the quality of crackers was investigated. Changes in total titratable acidity and pH were monitored during the fermentation of the sourdough (24 hours). In the dough for the production of gluten-free crackers, the influence of the addition of sourdough on the total titratable acidity and pH value was examined. The content of water, protein, fat, starch, crude fiber, pH value and total titratable acidity was determined by flour samples for the production of gluten-free crackers and gluten-free crackers. The influence of sourdough on the sensory properties of crackers was examined. The mineral composition of zinc was determined and the contribution of the daily recommended intake was assessed. In samples of crackers subjected to storage for 5, 10, 20 and 30 days, a change in water content was monitored. The length of fermentation had a significant impact on the dynamics of pH change and on the total titratable acidity during the fermentation of sourdough. The results of the study showed that the control sample has a higher pH value than the samples with sourdough. The reason for that is the development of acetic acid during fermentation. The change in water content in the crackers over 30 days was significantly higher in the control sample compared to the samples with sourdough. Crackers with sourdough contain a significantly higher percentage of protein, ash, fiber, zinc at the expense of reducing carbohydrates.

Since early February 2019, the SEIS (Seismic Experiment for Interior Structure) seismometer deployed at the surface of Mars in the framework of the InSight mission has been continuously recording the ground motion at Elysium Planitia. In this study, we take advantage of this exceptional data set to put constraints on the crustal properties of Mars using seismic interferometry (SI). To carry out this task, we first examine the continuous records from the very broadband seismometer. Several deterministic sources of environmental noise are identified and specific preprocessing strategies are presented to mitigate their influence. Applying the principles of SI to the single‐station configuration of InSight, we compute, for each Sol and each hour of the martian day, the diagonal elements of the time‐domain correlation tensor of random ambient vibrations recorded by SEIS. A similar computation is performed on the diffuse waveforms generated by more than a hundred Marsquakes. A careful signal‐to‐noise ratio analysis and an inter‐comparison between the two datasets suggest that the results from SI are most reliable in a narrow frequency band around 2.4 Hz, where an amplification of both ambient vibrations and seismic events is observed. The average autocorrelation functions (ACFs) contain well identifiable seismic arrivals, that are very consistent between the two datasets. Interpreting the vertical and horizontal ACFs as, respectively, the P‐ and S‐ seismic reflectivity below InSight, we propose a simple stratified velocity model of the crust, which is mostly compatible with previous results from receiver function analysis. Our results are discussed and compared to recent works from the literature.

The focus of the present paper is on the importance and significance of interculturality in teacher education. The paper analyzes the intercultural content of the curricula to develop the intercultural competencies of future teachers in Serbia and Bosnia and Herzegovina. The sample analyzed was the curricula of the universities of these two countries for the academic year 2018-2019. The analysis of the chosen documents examined the areas of teaching, content, as well as other elements that represent possible opportunities for developing the intercultural competencies of the students. The analyzed curricula do not offer an insight into the results of the teaching practice, which is one of the limitations of this study.  The findings on the poor ratio of intercultural elements in the curricula and the need for their revision, as well a necessity of introducing systematic intercultural education to teacher colleges and universities of education are a valuable contribution. Competent teachers will create a positive environment for proper intercultural communication and develop the intercultural sensitivity of their students thus promoting a culture of dialogue. The result obtained in the analysis can be an incentive to think thorough when creating curricula for educating teachers, both in initial and life-long learning so that they promote intercultural values.

Purpose This paper aims to highlight the importance of braille for visually impaired people and the possibility of printing it by using the ultra-violet (UV) inkjet printing technique. Design/methodology/approach The vision impairment, definitions and statistics, as well as braille letter and standards, are first reviewed. Then, the methods of printing braille have been discussed, with a focus on UV ink-jet printing. Finally, this study indicates a significant role of UV ink-jet printed Braille, its possibilities and its advantages. Findings Research studies in the field of UV ink-jet printed braille are showing that it is possible to print good legible braille of the adequate height of dots. This paper highlights some advantages of printing braille with UV ink-jet, like the possibility of achieving greater dot height than embossing and no need for printing form. Printing of additional elements on top of braille dot has also been tested, and possible use for differentiation of the written notation is shown. This paper also indicates the importance of technological and operating conditions in UV inkjet braille printing. It predicts a significant role of UV inkjet in braille printing. Originality/value This paper provides a detailed review of UV ink-jet printed braille: possibilities, advantages and application.

Economic thought always permeated human living. Economic thought and the development of economics as a discipline in the last few centuries made it central to the world order. However, the foundational problems that mainstream economics suffers from led to uncounted crises and issues within the same order that created it. A physicalist ontology, rationalist epistemology, axiological futility, and methodological deficiency are the problems of philosophical foundations of mainstream economics we reviewed in this paper. The methodology of this paper is qualitative and generally adopts the library research and critical content analysis methods to review and respond to identified foundational problems. Muslims islah and tajdid responses to the West and mainstream economics problems and issues found shape in Islamisation of Knowledge (IOK) and Islamic Economics (IE). The recent shift to Integration of Knowledge (IoK) universalizes the appeal and revives the zeal for IE development in light of IoK based on IOK in this paper. A thorough analysis of IOK, IoK, and IE responses to the West and mainstream economics enabled us to appraise it as the alternative and solution to the foundational problems. The paper clarified the way for future research in IE in light of IoK and directed the academia and industry towards economic reasoning based on robust foundations.

High-temperature materials are used in a wide range of industries and applications such as gas turbine engines for aircrafts, power and nuclear power plants, different types of furnaces, including blast furnaces, some fuel cells, industrial gas turbines, different types of reactors, engines, electronic and lighting devices, and many others. Demands for high-temperature materials are becoming more and more challenging every year. To perform efficiently, effectively and at the same time to be economically viable, the materials used at high temperatures must have certain characteristics that are particularly expected for applying under such extreme conditions, for example, the strength and thermal resistance. In the present review, some important requirements that should be satisfied by high temperature materials will be discussed. Furthermore, the focus is put on refractory concretes, ceramics, intermetallic alloys, and composites as four different categories of these materials, which are also considered in respect to possibilities to overcome some of the current challenges.

Bone morphogenetic proteins (BMPs) are known to induce new bone formation in vivo but treating trabecular bone defects with a BMP based therapeutic remains controversial. Here, we evaluated the safety and efficacy of a novel Autologous Bone Graft Substitute (ABGS) comprised of recombinant human BMP6 (rhBMP6) dispersed within an autologous blood coagulum (ABC) as a physiological natural carrier in patients with a closed distal radial fracture (DRF). We enrolled 32 patients in a randomized, standard of care (SoC) and placebo (PBO) controlled, double-blinded Phase I First in Human (FiH) clinical trial. ABGS was prepared from peripheral blood as 250 μg rhBMP6/mL ABC or PBO (1 mL ABC containing excipients only) and was administered dorsally via a syringe injection into the fracture site following closed fracture fixation with 3 Kirschner wires. Patients carried an immobilization for 5 weeks and were followed-up for 0 to 26 weeks by clinical examination, safety, serial radiographic analyses and CT. During the 13 weeks follow-up and at 26 weeks post study there were no serious adverse reactions recorded. The results showed that there were no detectable anti-rhBMP6 antibodies in the blood of any of the 32 patients at 13- and 26-weeks following treatment. Pharmacokinetic analyses of plasma from patients treated with ABGS showed no detectable rhBMP6 at any time point within the first 24 hours following administration. The CT image and radiographic analyses score from patients treated with AGBS showed significantly accelerated bone healing as compared to PBO and SoC at 5 and 9 weeks (with high effect sizes and P=0.027), while at week 13 all patients had similar healing outcomes. In conclusion, we show that intraosseous administration of ABGS (250 μg rhBMP6/mL ABC) into the distal radial fracture site demonstrated a good tolerability with no serious adverse reactions as well as early accelerated trabecular bone healing as compared to control PBO and SoC patients.

Although the Hippo transcriptional coactivator YAP is considered oncogenic in many tissues, its roles in intestinal homeostasis and colorectal cancer (CRC) remain controversial. Here, we demonstrate that the Hippo kinases LATS1/2 and MST1/2, which inhibit YAP activity, are required for maintaining Wnt signaling and canonical stem cell function. Hippo inhibition induces a distinct epithelial cell state marked by low Wnt signaling, a wound-healing response, and transcription factor Klf6 expression. Notably, loss of LATS1/2 or overexpression of YAP is sufficient to reprogram Lgr5+ cancer stem cells to this state and thereby suppress tumor growth in organoids, patient-derived xenografts, and mouse models of primary and metastatic CRC. Finally, we demonstrate that genetic deletion of YAP and its paralog TAZ promotes the growth of these tumors. Collectively, our results establish the role of YAP as a tumor suppressor in the adult colon and implicate Hippo kinases as therapeutic vulnerabilities in colorectal malignancies.

Abstract Objective We investigated the impact of multimorbidity and polypharmacy on the management of atrial fibrillation (AF) patients in clinical practice and assessed factors associated with polypharmacy and oral anticoagulation (OAC) use in AF patients with multimorbidity and polypharmacy. Methods A 14-week prospective study of consecutive non-valvular AF patients was performed in seven Balkan countries. Results Of 2712 consecutive patients, 2263 patients (83.4%) had multimorbidity (AF + ≥2 concomitant diseases) and 1505 patients (55.5%) had polypharmacy. 1416 (52.2%) patients had both multimorbidity and polypharmacy. Overall, 1164 (82.2%) patients received OAC, 200 (14.1%) patients received antiplatelet drugs alone and 52 (3.7%) patients had no antithrombotic therapy (AT). Non-emergency centre and paroxysmal AF were significantly associated with OAC non-use in patients with multimorbidity, whilst age ≥80 years and non-emergency centre were identified to be independent predictors of OAC non-use in patients with polypharmacy. Conclusions Multimorbidity and polypharmacy were common among AF patients in our study. AT was suboptimal and approximately 18% of multimorbid patients with polypharmacy were not anticoagulated. Pattern of AF and non-emergency centre were associated with OAC non-use in AF patients with multimorbidity, whilst non-emergency centre and age ≥80 years were associated with OAC non-use in AF patients with polypharmacy. Key Message Multimorbidity and polypharmacy are common among patients with AF. Antithrombotic therapy was suboptimal in AF patients with multimorbidity and polypharmacy. Approximately, 18% of multimorbid patients with polypharmacy were not anticoagulated.
