Published: January 2019

La Comisión Internacional de Protección Radiológica, ICRP, propuso una nueva metodología para el cálculo de coeficientes de dosis para trabajador ocupacionalmente expuesto que cambia la propuesta en las publicaciones 60 y 78 de la misma comisión. En este trabajo se reprodujeron los valores AF para hombre adulto reportados en la publicación 100 de la ICRP utilizando el software MCNPx y se calcularon con la misma metodología los SAFs para los compartimentos del HATM de mujer adulta, para electrones monoenergéticos dentro del rango de energías de 0.01 a 4 MeV. Se calcularon los SAFs en phantom voxelizados para hombre y mujer adulto, cuya estructura anatómica se reporta en la publicación 110 de la misma Comisión, usando la misma metodología de cálculo con el software MCNPx. Con estos datos se calcularon los coeficientes h(50) y e(50) para incorporación única por ingestión del 90Sr – 90Y, dada su importancia dosimétrica. Se consideraron las fracciones de absorción en intestino delgado reportados por la ICRP 78 y la metodología recomendada por la publicación 103 de la ICRP, encontrando valores de e(50) menores que los reportados por la ICRP en sus publicaciones. Finalmente se comparan los valores obtenidos con los reportados por Wei Bo Li et al.
Estudio in Silico de la reactividad y propiedades fisicoquímicas de aductos de Epóxido de Eugenol y 2-Metoxi-4-alilideno-2,5-ciclohexadieno-1-ona con glutation en Candida albicans
Authors: Rabanal-Sanchez Jhonatan , Ruiz-Quiroz Julio
Published: January 2019

El eugenol es un alilbenceno con actividad antifúngica, diversos estudios han demostrado su capacidad de inhibir el crecimiento de Candida albicans. Se ha propuesto la formación de aductos entre un derivado del eugenol (2-metoxi-4-alilideno-2,5-hexadieno-1-ona) y glutatión como un mecanismo de estrés oxidativo. Asimismo, otro derivado del eugenol, epóxido de eugenol, tiene teóricamente la capacidad para formar aductos. Por lo tanto, este estudio determinó in silicolas propiedades fisicoquímicas de estos aductos y su reactividad en microorganismos aeróbicos. Se encontró que estos aductos tienen baja hidrofobicidad, por lo que, tendrían baja capacidad para atravesar membranas biológicas y por tanto una distribución intracelular. Asimismo, las reacciones químicas que originan estos aductos son termodinámicamente favorables. Por último, estos aductos son susceptibles a modificaciones químicas en microorganismos aeróbicos; estas reacciones podrían ser catalizadas por enzimas como el citocromo P450.

Published: January 2019

Background and aims

Despite increases in female gambling, little research investigates female-specific factors affecting gambling behavior (GB). Although research suggests that some addictive behaviors may fluctuate across menstrual cycle phase (MCP), gambling requires further investigation. In two studies, we examined associations between MCP and three risky GBs: time spent gambling, money spent gambling, and the probability of consuming alcohol while gambling. Associations between MCP and negative affect were also examined in Study 2. We predicted that, consistent with self-medication theory, increases in negative affect (Study 2) and risky GBs (Studies 1 and 2) would occur premenstrually/menstrually relative to other phases.

Methods

Data were obtained from 33 female gamblers using a retrospective timeline followback procedure (Study 1) and from 20 female gamblers using a prospective 32-day, daily diary method (Study 2). In Study 2, salivary progesterone levels verified self-reported MCP validity.

Results

Findings revealed significant, but somewhat inconsistent, MCP effects on GBs across studies. The self-medication hypothesis was partially supported. Increases relative to another MCP(s) were found for alcohol consumption while gambling premenstrually, time spent gambling menstrually/premenstrually, money spent gambling menstrually, and negative affect premenstrually. Unexpectedly, findings more consistently indicated that GBs increased during ovulation, suggestive of enhanced reward sensitivity. Progesterone assays validated self-reported MCP (Study 2).

Discussion and conclusions

The results suggest a role of ovarian hormones on negative affect and GBs in females. This research could lead to the identification of female-specific factors affecting gambling and the development of more effective interventions for females with, or at risk for, problematic gambling.

Published: January 2019

This article was migrated. The article was not marked as recommended. Introduction: Academic teaching has been present in society for centuries. However, its methodology has not significantly changed. Though various articles were published analysing students´ satisfaction with the teaching method, there is still scarce data on the knowledge improvement associated with different methodologies. Therefore, the endpoints of this research were: 1) analyse the impact of Sophistic lectures in knowledge acquisition in medical students and 2) examine knowledge assessment using new digital technologies, compared with a more traditional paper-based method. Methods: A repeated measures design was implemented in four classes of 4th year medical students, lectured by the same teacher on the same subject. A scientifically validated questionnaire was applied before and after each class, in paper and web-based tool Sli.do to two classes each. Results were compared by means of descriptive statistics. Results: 55 answers were obtained in paper and 34 in Sli.do. Paper method questionnaires had mildly lower scores before and after class (46% and 74,2%, respectively) when compared with Sli.do (52,4% and 82,9%, respectively). Although basal scores were different among methods, both revealed a similar relative knowledge improvement, comparatively to the respective baseline (61,3% vs. 58,2%, respectively). Discussion & Conclusions: The results showed that Sophistic classes are effective in learning, independent of evaluation method, which reassure that the task of the teacher is important and effective. This study supports the use of digital-based tools to assess learning in classes since they are more time-efficient, more ecological and logistically easier. Finally, assess the information that is being effectively taught to the students has several benefits for the teachers, the university and ultimately the students. Since a digital storage of the collected data makes it possible to carry out more effective internal audits over time, allowing the improvement of areas with lower results, benefitting the entire academic community.

Published: January 2019

This article was migrated. The article was marked as recommended. Purpose: The purpose of this study was to compare attitudes regarding cost-consciousness between student populations at two medical schools in the United States and Canada. Method: We conducted a cross-sectional survey of students at Harvard Medical School and University of Toronto. We performed chi-square analyses comparing responses from the two institutions. Results: Response rates were 48% (n=162) and 45% (n=228) at Harvard and the University of Toronto, respectively. At both institutions, >96% of students agreed clinicians at all stages of training should be familiar with cost-conscious decision-making, 80% agreed physicians are responsible for discussing healthcare costs with patients, and over 80% felt they had too little education on the topic in medical school. Students differed in opinions about the extent to which patients should inquire about costs, with students at Harvard more likely to endorse this opinion compared with those from Toronto (51% vs 28%, respectively), and differed over whether cost-consciousness led to rationing of healthcare (Harvard 30% vs Toronto 51%). Fewer than 10% of all students expressed concerns that incorporating costs into care was unethical. Overall, 85% of students from both countries would like more formal teaching on this topic. Discussion: Students from both schools strongly endorsed a need to learn more about cost-conscious decision-making. Findings suggest students in both systems can benefit from learning similar core concepts related to high-value, cost-conscious care, and teaching in this topic can be customized to reflect specific differences in expectations and practices in the two healthcare systems.
Joana Nolais e o enigma de gênero: uma discussão psicanalítica da transexualidade
Authors: Martinez Viviana Carola Velasco , Angeli Gustavo
Published: January 2019

Resumo: O presente artigo aborda a transexualidade, como parte da pluralidade do gênero, dentro da perspectiva da Teoria da Sedução Generalizada, de Jean Laplanche, a partir da qual analisamos a autobiografia de Joana Nolais. Discutimos o gênero como um dos conteúdos das mensagens enigmáticas provenientes do adulto, transmitidas à criança através dos cuidados básicos. Por serem enigmáticas, isto é, da ordem do sexual e, por isso, inconscientes também para o próprio adulto, tais mensagens são traumáticas por excelência, o que exigirá da criança um trabalho de tradução, auxiliada pelo sexo anatômico e a cultura, enquanto organizadores. Consideramos a transexualidade como uma das possíveis traduções do enigma do gênero do adulto efetuadas pela criança desde muito cedo.
Business cycles and earnings management strategies: a study in Brazilian public firms,
Authors: Paulo Edilson , Mota Renato Henrique Gurgel
Published: January 2019

ABSTRACT This study contributes to the literature dealing with the influence of macroeconomic factors on accounting information quality, since it analyzes the earnings management strategies of firms, specifically identifying different discretionary behaviors among economic cycles: 1) different levels of earnings management through accruals between phases of the business cycle, and 2) the trade-off between earnings management through accruals and real earnings management. The results indicate that the accounting information reported should be analyzed with greater caution by its users, especially in periods of great economic oscillations, when managers can increase or reduce opportunistic behavior. The research population comprised non-financial companies with shares traded on the São Paulo Stock, Commodities, and Futures Exchange (BM&FBovespa) and the sample was composed of 247 firms per year, covering the period from 2000 to 2015 and totaling 2,501 observations. The phases of business cycles were used as a proxy for the economic environment and were based on Schumpeter's (1939) study, which divides an business cycle into four distinct phases: expansion, recession, contraction, and recovery. Discretionary accruals were estimated according to the Pae (2005) and Paulo (2007) models. Real earnings management was estimated as described by Roychowdhury (2006), using only the abnormal behavior of production costs and operational decisions. The results of this research show that earnings management strategies, using either accruals or real manipulation, as well as the choice between these strategies, are impacted by the economic environment. The evidence suggests that managers have different opportunistic behavior in each phase of the business cycle. Specifically, they increase the level of discretionary accruals in contractionary phases and reduce it during recoveries, while they manage earnings downwards via real manipulation in recessions and contractions.
POLÍTICAS PÚBLICAS E SUAS PÓS-VIDAS: MERECIMENTO E CIDADANIA HABITACIONAL NO BRASIL DA MOBILIDADE SOCIAL
Authors: Kopper Moisés
Published: January 2019

Políticas econômicas e sociais construíram o caminho para a redução das desigualdades e melhoria de vida de milhões de brasileiros nos anos de 2000. Com base em pesquisa entre recipientes do programa Minha Casa, Minha Vida, discute-se os nexos etnográficos entre políticas públicas e mobilidade ascendente. Seguindo a trajetória pública e privada de dona Hilda – uma senhora negra e pobre de 97 anos que vive na periferia de Porto Alegre – argumento que a mobilidade emergente no cerne da ampliação das intervenções de governo materializou-se em alinhamentos difusos entre políticos locais, agentes de mercado, planejadores, lideranças e “cidadãos desejantes”. Para navegar esses terrenos políticos, econômicos e comunitários, dona Hilda engajou-se num trabalho por cidadania habitacional e merecimento que a converteu na personagem exemplar do programa. Deslindando os limites morais entre discurso, história e subjetividade, a cartografia desses fragmentos está mais bem equipada para explorar as pós-vidas das políticas públicas no Brasil recente.
Current Treatment Options in Gastroenteropancreatic Neuroendocrine Carcinoma

Published: January 2019

Poorly differentiated gastroenteropancreatic neuroendocrine carcinomas (GEPNECs) are a rare neoplasm with a bleak prognosis. Currently there are little prospective data available for optimal treatment. This review discusses the current available regimens and the future direction for the treatment of GEPNECs. Treatment plans for GEPNECs are often adapted from those devised for small cell lung cancer; however, differences in these malignancies exist, and GEPNECs require their own treatment paradigms. As such, current first-line treatment for GEPNECs is platinum-based chemotherapy with etoposide. Studies show that response rate and overall survival remain comparable between cisplatin and carboplatin versus etoposide and irinotecan; however, prognosis remains poor, and more efficacious therapy is needed to treat this malignancy. Additional first-line and second-line treatment options beyond platinum-based chemotherapy have also been investigated and may offer further treatment options, but again with suboptimal outcomes. Recent U.S. Food and Drug Administration approval of peptide receptor radionuclide therapy in low- and intermediate-grade neuroendocrine tumors may open the door for further research in its usefulness in GEPNECs. Additionally, the availability of checkpoint inhibitors lends promise to the treatment of GEPNECs. This review highlights the lack of large, prospective studies that focus on the treatment of GEPNECs. There is a need for randomized control trials to elucidate optimal treatment regimens specific to this malignancy.
Simulation of water dissipation in urban buildings
Authors: Zhou Jinjun , Liu Jiahong , Wang Hao , Wang Zhongjing
Published: January 2019

Building water dissipation (BWD) refers to the change of water into vapour during water use activities in the building. The intention of the work described in this paper was to explore the BWD mechanism and establish a calculation model for BWD. The main research methods included experimental monitoring, a questionnaire survey and data mining. The results of this work showed that the capacity of buildings and the building area determine the type of water dissipation whereas the building population determines the BWD volume. The BWD calculation model was thus built based on two key parameters – building area and building  population. Multi-variate regression fitting was used to analyse and study the other factors that influence BWD, such as water consumption, number of floors and so on. Using cluster analysis, 100 sample buildings were divided into different categories. Ordinary least squares regression was used to fit the multi-variate regression for the BWD of sample buildings. The results showed that the classification of buildings by cluster analysis can enhance the fitting effect of multi-variate regression of BWD.
New Insights into the Mechanism of NO3 - Selectivity in the Human Kidney Chloride Channel ClC-Ka and the CLC Protein Family
Authors: Lagostena Laura , Zifarelli Giovanni , Picollo Alessandra
Published: January 2019

Significance Statement

The human chloride channels ClC-Ka and ClC-Kb, in complex with their accessory subunit barttin, are essential for NaCl reabsorption in the nephron. Mutations of ClC-Ka, ClC-Kb, or barttin cause type III and IV Bartter syndrome, characterized by renal salt wasting, hypokalemic metabolic alkalosis, and other effects. Using electrophysiologic techniques and mutational analysis, the authors show that the mechanism of discriminating Cl− versus NO3
− anions in the human ClC-Ka channel is unique in the CLC protein family, and they identified previously unimplicated residues as responsible for anion selectivity. This represents significant progress in better understanding of the relationship between structure and function of kidney channels ClC-Ka and ClC-Kb and of CLC proteins in general.

Background

The mechanism of anion selectivity in the human kidney chloride channels ClC-Ka and ClC-Kb is unknown. However, it has been thought to be very similar to that of other channels and antiporters of the CLC protein family, and to rely on anions interacting with a conserved Ser residue (Sercen) at the center of three anion binding sites in the permeation pathway Scen. In both CLC channels and antiporters, mutations of Sercen alter the anion selectivity. Structurally, the side chain of Sercen of CLC channels and antiporters typically projects into the pore and coordinates the anion bound at Scen.

Methods

To investigate the role of several residues in anion selectivity of ClC-Ka, we created mutations that resulted in amino acid substitutions in these residues. We also used electrophysiologic techniques to assess the properties of the mutants.

Results

Mutations in ClC-Ka that change Sercen to Gly, Pro, or Thr have only minor effects on anion selectivity, whereas the mutations in residues Y425A, F519A, and Y520A increase the NO3
−/Cl− permeability ratio, with Y425A having a particularly strong effect.

Conclusion

s ClC-Ka’s mechanism of anion selectivity is largely independent of Sercen, and it is therefore unique in the CLC protein family. We identified the residue Y425 in ClC-Ka—and the corresponding residue (A417) in the chloride channel ClC-0—as residues that contribute to NO3
− discrimination in these channels. This work provides important and timely insight into the relationship between structure and function for the kidney chloride channels ClC-Ka and ClC-Kb, and for CLC proteins in general.
Panorama urgente sobre la mediatización de la circulación y algunos de sus estudios

Mediatización y narratividad
Authors: Traversa Oscar
Published: January 2019

Se hace referencia en el presente trabajo al estado del conocimiento en torno a las relaciones entre Mediatización y narratividad con la finalidad de examinar, y a la vez, destacar la pertinencia de abordarlo. Las razones se presentan como evidentes: la narración como procedimiento, tanto la factual como la ficcional, se encuentran asociadas en toda la extensión del desenvolvimiento de nuestra especie y distribuidas, con características particulares, en todos los agrupamientos humanos y en el conjunto de los recursos comunicacionales. En el momento actual los procedimientos narrativos se hacen presente de manera protagónica, tanto en medios “tradicionales” como los derivados de las nuevas tecnologías digitales. Se concluye acerca del intervalo de manifestación de la narratividad y los aportes que pueden esperarse de la semiótica y del concurso de otras ciencias sociales.

Fundamentos epistemológicos transdisciplinares de educación y neurociencia
Authors: Fuentes Canosa Adela , Collado Ruano Javier
Published: January 2019

The emergence process of the new area of knowledge, product of the convergence between the fields of neuroscience and education, is still in its consolidation stage. At this point of disciplinary evolution, it is essential to define a multidimensional framework for creation of knowledge, in order to support the consilience between the academic fields involved. In this paper, a critical review of the literature associated with the epistemological questions is carried out, which underlies the attempt of communication between disciplines, providing a theoretical framework that starts from basic epistemic questions, to finally base the synergy between the sciences of education and the brain sciences. In the set of reviewed literature, the state of terminological undefinedness of the area referred to as “educational neuroscience”, “neuroeducation”, or “mind, brain and education” emerged explicitly. This inconsistency in the nomenclature is correlated in the epistemological ambiguity of the different proposals, as well as the need to overcome unidirectional models of communication. In conclusion, this type of relational model, located in the interdisciplinary framework, could be demanding an evolution towards a transdisciplinary approach: with the establishment of an effective bi-directionality that incorporates professionals and educational researchers as active agents in knowledge construction processes of this new field.
Sobre lo “neuro” en la neuroeducación: de la psicologización a la neurologización de la escuela
Authors: Ocampo Alvarado Juan Carlos
Published: January 2019

Abstract The objective of this article is to analyze the triadic relationship between education, psychology and neuroscience within the framework of neuroeducation. To this end, an exhaustive review of the most relevant literature on the subject was carried out. The historical precedents of neuroeducation can be traced back to the introduction of psychological discourse in education, which later transformed into the psychologization of school. Arguably, the irruption of the neuro in the culture and the advent of the new neurosubjectivities ended up dethroning psychology of its privileged position in the educational context. Under promises of liberation, independence and scientificity, neuroeducation prospered precipitously without addressing the multiplicity of philosophical, methodological and ethical difficulties that still plagues it. However, the structural relationship between psychology and neuroscience reveals the inability of the latter to detach itself from the psi paradigm. Moreover, from the counterpsychology theory and considering its analog behavior, it can be argued that the neuro, rather than an independent stage, is an extension of the psi conditioned to this epoch. Under this approach, neuroeducation is not an alternative to psychological predominance but a return to it which threatens neurologization. Thus, it is imperative that learning is reconnected to culture, educational spaces are reconquered, and the teachers are made aware of their agency so that education can, without ignoring the valuable contributions of the other disciplines, recognize itself as an autonomous knowledge, eminently integrationist and independent.
Matrices decolonizadoras en la comunicación para entablar un diálogo con Occidente
Authors: Valdez-López Orlando E. , Romero-Rodríguez Luis M. , Hernando Gómez Ángel
Published: January 2019

Abstract This paper examines the premises of decolonization in the Communication Studies and practice that challenges the West civilization based on the critical thinking of precursors and contemporary intellectuals of Latin America. The principles and values of communication and life are recovered for the constitution of a study and the exercise of intercultural communication for well-living, evidencing the need for an alternative communication epistemology based on matrices formulated by authors such as Luis Ramiro Beltrán and Erick Torrico under the premise of “liberation communicology” against the progress-mercantilism and the modernity of communication. This approach focuses on the horizontality and the circularity of the communicative process, and above all in the recovery of its ontological and integral level in the study-knowledge and exercise of communication. Philosophy and the Amazon do not claim the annulment of the way of reasoning and the Western procedure, the embargo, the search for dialogue and respect for indigenous wisdom and community life. Consequently, unity in diversity is sought, understood as the comprehensive understanding of the thought of communicative communication, demonstrating the need to establish a dialogue of knowledge between indigenous wisdom and knowledge of the West, assuming as a challenge to urge to live in harmony between human beings and nature, where communication is the link for the study and practice of the culture of life.
Open House? Class-Specific Career Opportunities within German Universities
Authors: Blome Frerk , Möller Christina , Böning Anja
Published: January 2019

This article focuses on the development of class-specific inequalities within German universities. Based on data on the social origin of students, doctoral students, and professors in the long-term cross-section, the article views the empirically observable dynamic of social closure of higher education since the 1950s. The focus of interest is on the level of the professorship. Data show that career conditions for underprivileged groups have deteriorated again. This finding is discussed in the context of social closure theories. The article argues that closure theories consider social closure processes primarily as intentional patterns of action, aimed at a strategic monopolization of participation, and securing social power. Such an analytical approach means that unintended closure processes remain understudied. Our conclusion is that concealed modes of reproduction of social structures ought to be examined and theorized more intensively due to their importance for the elimination of social inequality within universities.
Access to Higher Education: An Instrument for Fair Societies?
Authors: Goastellec Gaële , Välimaa Jussi
Published: January 2019

Access to higher education (HE) has a long history. To offer a view on the current debates and worldwide issues regarding access to HE, this editorial depicts how the control of educational access has historically been used as an instrument of governance at the interface of two processes: social stratification and the territorialisation of politics. Access to HE has remained embedded in these large structural processes even though HE has expanded from a highly elitist institution into mass education systems with equity of educational opportunities having become a desirable goal across societies. Analysing these processes helps understand the complex mechanisms producing inequalities in HE today, which are brought together by the ten articles composing this special issue. Tacking stock of how inequalities in access are produced in different continents, countries, HE Institutions, applying to different social groups though evolving mechanisms, these articles document the importance of contrasting methodological and theoretical approaches to produce comprehensive knowledge on this sensitive issue for democratic societies.

O referencial teórico para a análise é a semiótica da cultura, de Iúri Lotman, além de aspectos centrais das teorias do jogo e dos megaeventos esportivos. O objetivo é contribuir para melhor entendimento da Copa do Mundo como texto da cultura e para a reflexão sobre as práticas realizadas nesse evento e seus impactos no público apaixonado por futebol.
Dinamismo, complejidad y especificidad de los litorales estuarinos: análisis de la dinámica litoral en Punta Atalaya, Buenos Aires, Argentina
Authors: D'Amico G. , Fucks E. , Carut C.
Published: January 2019

Los litorales son espacios complejos y dinámicos, producto de la interacción entre las dinámicas naturales y las valoraciones sociales a lo largo del tiempo. Esta interacción desencadena procesos variados que confieren especificidad a sus costas. En los litorales estuarinos se forman ambientes intermareales denominados marismas, intensamente modificadas en las grandes metrópolis urbanas.La dinámica de estos ambientes ha sido extensamente estudiada en el hemisferio norte, encontrándose escasas investigaciones en el hemisferio sur. En el presente trabajo se realiza un estudio multitemporal de una marisma de formación reciente en la costa de Punta Atalaya (partido de Magdalena, Buenos Aires, Argentina), situada en el sector intermedio de la costa argentina del estuario del Río de la Plata, utilizando la línea de costa como indicador del límite exterior de este ambiente. Se partió de su identificación en fotografías aéreas e imágenes de satélites de alta resolución en el periodo 1929-2016. Mediante la utilización de un software especializado en el análisis multitemporal de cambios, inspecciones en el campo y revisión de bibliografía general y específica, se realizó una aproximación explicativa de la dinámica litoral de esta franja territorial.Se determinó que la costa de Punta Atalaya presenta una tendencia progradante en el último siglo, aunque cambios en la microescala temporal y espacial son detectados a lo largo de todo el periodo, respondiendo a dinámicas acrecionales y erosivas que derivan de la interacción de procesos biológicos, sedimentarios, meteorológicos y sociales. Cada proceso puede desencadenar múltiples respuestas y tener impactos diferenciales en tiempo y espacio. En este sentido, se cuestionan las nociones de equilibrio utilizadas en las clásicas investigaciones acerca de los balances sedimentarios costeros. El sector correspondiente al área de estudio no posee categoría de área protegida, por lo que su valoración ambiental en este sentido debe contemplar la dinámica del mismo.
Four-year soil erosion rates in a running-mountain trail in eastern Iberian Peninsula
Authors: Salesa D. , Cerdà A.
Published: January 2019

During the last decades, the use of mountain trails for running is more and more popular. New trails are opened to allow the runners to practice and compete. This form of human impact on the landscape is new as the new trails do not follow the conservation strategies in design and maintenance as traditional mountain trails constructed by farmers, shepherds and muleteers do. This impact of sport events in nature is not measured and we know little about this impact on vegetation, fauna and soils. We surveyed in September 2018 a trail that was opened in September 2014 and was used for four official mountain trail races, and for training by local runners. Our interviews with organizers and users show that 1054 runners passed during the competition days (4 races in 4 years) and over the 4-year period the trail was used approximately 43,800 times by a runner. We measured the current topography and calculated the soil lost. The results show extremely high erosion rates in the sloping terrain, with the highest rates in the north-facing slope, reaching up to 180.29 Mg ha-1 y-1, while in the flat section of the trail soil erosion rates are 107.56 Mg ha-1 y-1 and in the south-facing slope trail 128.93 Mg ha-1 y-1. Our study demonstrates that (i) soil erosion rates on trails can be easily estimated by measuring the deepest trail position enabling fast and cheap surveys; and (ii) that there is a need to establish conservation strategies on new trails to avoid non-sustainable soil losses in the Mediterranean mountains due to the sport activities such as the mountain trail races.

Published: January 2019

Background: Role of CT scan in sinonasal disease is proved by many published articles. Most of them are having small sample size, poorly defined protocol of CT reporting and does not mention the window width and window level of the software. We did this study to include these points and tried to have sample size of at least 200.

Methods: 231 patients included in the study. After clinical examination CT PNS was done. A strict protocol was maintained for the timing of CT, window settings (to get highest bony definition) and for the reporting of CT.  

Results: Few common anatomical variations were agger nasi (61.9%), DNS in 50.6%; concha bullosa (18.6%), paradoxical MT (20.3%), Onodi Cells (21.6%) and Haller cells (11.3%). Most common subtypes amongst some anatomical variations include middle meatal drainage of frontal recess (58.8%), type I frontal cell (7.1%), type I ethmoid roof (48.9%), type I attachment of UP (58.8%) and sellar type of sphenoid pneumatization (68%). CT has 100% sensitivity and specificity in detecting the diseased sinuses correctly. Except from 11.8% cases in which frontal recess drainage could not be assessed, all other anatomical variation were same intra-op as shown by CT. In fungal rhinosinusitis anatomical variations were difficult to detect by CT.

Conclusions: This study proves that CT-PNS gives us the detailed and near exact picture of the disease with its extent as well as of existing anatomical variations in non-neoplastic sino-nasal diseases except in FRS cases where in anatomical variations are difficult to analyze.

Background: Importance of HRCT before middle ear surgery is proved by many published articles but most of the studies were done without evaluating the accuracy of clinical judgment at the same time.

Methods: All the patients of CSOM in whom the middle ear surgery was planned were included in the study. Total number of sample size was 80 patients. Group A: 20 patients in which HRCT temporal bone was indicated as a routine evaluation before middle ear surgeries. Group B: 60 patients in which HRCT temporal bone was not indicated.  

Results: Maximum 43.75% (35) patients belong to 21 to 30 yrs. F: M is 1.5:1. Unilateral ear disease is more common (62.5%). 41.8% had mucosal type while 16.25% had squamosal type of COM. 77.5% ears found to have hearing loss. Conductive hearing loss was the most common (43.13%). HRCT in comparison with Intra-op had Kapa value of 1 (Aditus blockage & Tegmen erosion), 0.6 (sinus plate erosions), 0.5 (malleus, Incus, stapes erosions), 0.48 (Ossicular chain status), 0.46 (Scutum erosion), 0.4 (LSC fistula) and 0.3 (fallopian canal erosions. Clinical judgment in comparison with intra-op had kapa value of 1 (stapes erosion), 0.96 (aditus blockage), 0.79 (Incus erosion), 0.78 (malleus erosion) and 0.76 (ossicular chain status).

Conclusions: Clinical judgment is as good as or even better than CT in presuming/detecting at least individual ossicular erosions, ossicular chain status, aditus blockage and HRCT temporal bone should be reserved for high risk and complicated cases.
Evaluation of Clinical Effectiveness of Bioactive - Glass and Platelet - Rich Fibrin in the Management of Intrabony Defects - A Comparative Study

Published: January 2019

Background: Platelet-Rich Fibrin (PRF), the second-generation platelet concentrate has various fringe benefits over other platelet concentrates. Just finite number of research works have concentrated on the utilization of PRF in combination with various kinds of bone grafts in intra-bony defects. Objective: The primary intention of this study was to determine the clinical and radiographical efficacy of Bioactive-glass with and without autologous PRF in the management of three-wall vertical defects. Methods: Twenty intrabony defects were arbitrarily chosen and treated either with Bioactive Glass (BG) alone or in mix with PRF (PRF/BG). Clinical parameters were documented preoperatively (baseline) and at six months post-operatively. Radiographic analysis was performed at baseline, third and sixth-month intervals. Results: The study outcome demonstrated that both treatment approaches were effectual. Significant decrease in the mean probing depth and gain in clinical attachment was observed in BG+PRF and BG groups as compared to baseline but was statistically insignificant at 6 months. (p=0.475, p=0.245 respectively). Radiographically, reduction in defect depth was significantly greater in BG+PRF group than BG group (p=0.007) at 6 months. Conclusion: Within the limitation of the current study, it is proposed that both treatment modalities are effective in the management of 3-wall intra-bony defects. The outcomes additionally uncovered that incorporation of PRF with BG has more successful and promising results. Hence in future, clinical trials with bigger sample size may be employed to further explore the potential benefits of PRF as a sole grafting material.

Published: January 2019

Root stumps serve as pillars which can be utilized effectively as for future restorative needs in esthetic zones. Enhancing the white and depleting the pink may serve the purpose. Clinical Crown Lengthening Surgery (CCLS) is a traditional procedure which can be utilized to rehabilitate esthetics. The study involves a 30-year old patient with fractured crown irt 13. Crown lengthening was performed with apically repositioned flap and osseous reduction of 2 mm such that the new exposed tooth was approximately 4mm in length. The positive architecture was bone was established and 3 mm of attached gingiva was preserved. Root canal therapy followed by post and core was performed and the prosthesis was fabricated postsurgery. With the 22nd century approaching and dental implants being the new fad, it is still our responsibility to try to preserve what has been provided by nature to prevent us from becoming fictitious entities.

Published: January 2019

Introduction: Influenza A (H1N1) is the most recent of the pandemic diseases that has affected the world's population. The aim of this study was to assess knowledge, attitudes and behaviours regarding H1N1 pandemic among Malaysian dental students. Methodology: The data was collected using a self-administered questionnaire and results were analysed using SPSS version 15. Results: The most common symptoms identified were fever (50.8%), breathing difficulty (41.0%), and cough (39.3%). It was considered to be a moderately dangerous infection by approximately one third of the students (31.1%). Majority (88.9%) of the students agreed that washing hands with soap is the most effective preventive measure. It was followed by travel restriction that was reported by 77% of them as a preventive measure for the pandemic. Conclusion: This study concluded that a large number of students did not have complete awareness about disease transmission, preventive measures, vaccinations, and treatments available.

Aim. The aim is to identify the differences in the accumulation of manganese, zinc, copper and molybdenum in the hair of farm animals (cows and goats) and their spatial differentiation in the valley of the Lower Dniester. Methods. Sampling and sample preparation were carried out in accordance with generally accepted methods. The determination of metal content in hair samples was carried out in accredited laboratories using atomic absorption spectrometry (AAS) and Inductively Coupled Plasma Spectroscopy (ICP-S). Results. For the first time, data are presented on the content of biogenic metals (manganese, zinc, copper, molybdenum) in the hair of the tail of black-and-white cows and Russian White and Saanen goats in the valleys of the Lower Dniester. Conclusions. It is shown that the concentration of trace elements in the hair of farm animals reflects the relative homogeneity of the biogeochemical conditions of the Lower Dniester valley. It is established that cows and goats are characterized by a sharply differing elemental status for the studied metals estimated on the basis of an analysis of their concentrations in the hair of the tail. At the same time, the effect of hair color on the content of elements was revealed only for molybdenum in cows, and for goats there were no significant interbreed differences in metal concentrations.

Aim. The aim of the research is to study the potential nesting sites of the Spanish sparrow (Passer hispaniolensis) on the northwest coast of Crimea. Methods. Material was compiled during 2016-2018. The generally accepted methods of road and foot route census study were applied. Nesting stations were explored: nests of storks, birds of prey and corvids, forest belts and reed beds. Results. On the basis of research, the presence of Passer hispaniolensis in the north-western Crimea, in particular, within the borders of the Lebyazhy Islands («Swan Islands») specially protected natural area, has been established. It is revealed that for nesting, this species of sparrow prefers the areas close to fields and is not often found in human settlements. During the nesting period, an increase in the number from 15 to 45 pairs was noted. The greatest number of breeding pairs of spanish sparrow is found in the nests of the white stork. Late arriving birds form colonies on trees in close proximity to stork nests. Conclusion. Nesting of Passer hispaniolensis is most likely due to changes in the hydrological regime and land use structure, since rice crop rotation (until 2014) has been replaced by other grain crops (barley, wheat) and tilled crops (sunflower, maize). Thus, at present, the breeding ornithofauna of the protected area is represented by 92 species of birds.
