East of the West: Repossessing the Past In India
Authors: Chowdhury Indira , Mandal Srijan
Published: January 2018

Public history, as it is practised in India, defies easy attempts at classification. This is partially because hardly anything that would be recognised as public history is identified as such by its author(s). For the term, despite its ever-increasing acceptance outside India as a discipline and a practice distinct from history, has yet to gain any currency within India. Any attempt to identify works that are self-consciously public history in the Indian context will likely not yield much fruit. Nor, for that matter, will borrowing any of the many definitions of the term from the West and trying to find works that adhere to it in India. Instead, this chapter will try to highlight the myriad forms that public engagements with the past have taken place in India. This article focuses specifically on museums, arguably the preeminent site of public engagements with the past in India. To that end, it will look at a new generation of museums that are charting new paths towards enabling a better public engagement with the past. It will also analyse a few institutional forms of public engagements with the past.
One Monument, One Town, Two Ideologies: The Monument to the Victory of Bolzano-Bozen
Authors: Angelucci Malcolm , Kerschbamer Stefano
Published: January 2018

This article offers a critical reading of the first major attempt to publicly come to terms with the presence of an invasive and ideologically charged fascist monument in the border town of Bolzano-Bozen, in South Tyrol, Italy. The ‘Monument to Victory’, commissioned by Mussolini and inaugurated in 1928 to celebrate the annexation of the province after WWI, is the symbolic centre of a discourse that divides the town along an ethno-linguistic axis. To this day, this creates ongoing political tensions, fostering extreme views in both Italian and German speaking communities. To neutralise this symbolic power while preserving its supposed artistic value, a permanent exhibition inaugurated in 2014 inside the artefact tries to offer an historical explanation and contextualisation, and foster a new, inclusive and democratic discourse around the past. This article discusses this exhibition as a counter-monument, which directly challenges the ideology of the original. In interpreting the scientific aims and choices of the historians involved, and the architectural and curatorial strategies, it questions their dialogical underpinning discourse. The results lay bare an agenda to establish the site as a new monologic myth of origin for the democratic town of the future; one that aims at producing a ‘democratic and reconciled’ citizen through a prescriptive perlocutionary experience.
Climatological study of a new air stagnation index (ASI) for China
and its relationship with air pollution
Authors: Huang Qianqian , Cai Xuhui , Wang Jian , Song Yu , Zhu Tong
Published: January 2018

Abstract. Air stagnation index (ASI) is a vital meteorological measure of the atmosphere's ability to dilute air pollutants. The original metric adopted by US National Climatic Data Center (NCDC) is found not well suitable to China, because the decouple between upper and lower atmospheric layer results in a weak link between the near surface air pollution and upper-air wind speed. Therefore, a new threshold for ASI is proposed, consisting of daily maximal ventilation in the atmospheric boundary layer, precipitation and real latent instability. In the present study, the climatological features of this newly defined ASI is investigated. It shows that the spatial distribution of the new ASI is similar to the original one; that is, annual mean stagnations occur most often in the northwest and southwest basins, i.e., Xinjiang and Sichuan basins (more than 180 days), and the least over plateaus, i.e., Qinghai–Tibet and Yunnan plateaus (less than 40 days). However, the seasonal cycle of the new ASI is changed. Stagnation days under new metric are observed to be maximal in winter and minimal in summer, which is positively correlated with air pollution index (API) during 2000–2012. The correlation between ASI and concentration of fine particulate matter (PM2.5) during January 2013 of Beijing is also investigated. It shows that the new ASI matches the day-by-day variation of PM2.5 concentration very well and is able to catch the haze episodes in that month.
Synthesis and characterization of peroxypinic acids as proxies for
highly oxygenated molecules (HOMs) in secondary organic aerosol

Published: January 2018

Abstract. Peroxy acids might contribute significantly to particle toxicity and were recently found to be involved in new particle formation in the atmosphere. However, a lack of suitable analytical methods for the detection and characterization of peroxy acids in the particle phase is currently hindering the quantitative investigation of their contribution to these important atmospheric processes. Further development of appropriate techniques and relevant standards is therefore urgently needed. In this study, we synthesized three peroxypinic acids, developed a liquid chromatography separation method and characterised them with tandem mass spectrometry. The observed fragmentation patterns clearly distinguish the different peroxypinic acids from both the acid and each other, showing several neutral losses previously already observed for other peroxy acids. Both monoperoxypinic acids were found to be present in secondary organic aerosol generated from ozonolysis of α-pinene in laboratory experiments. The yield of monoperoxypinic acid formation was not influenced by humidity. Monoperoxypinic acid quickly degrades on the filter, with about 60 % lost within the first 5 hours. This fast degradation shows that time delays in traditional off-line analysis will likely lead to severe underestimates of peroxy compound concentrations in ambient particles.
Disentangling the rates of carbonyl sulphide (COS) production and
consumption and their dependency with soil properties across biomes
and land use types

Published: January 2018

Abstract. Soils both emit and consume the trace gas carbonyl sulphide (COS) leading to a soil-air COS exchange rate that is the net result of two opposing fluxes. Partitioning these two gross fluxes and understanding their drivers are necessary to estimate the contribution of soils to the current and future atmospheric budget of COS. Previous efforts to disentangle the gross COS fluxes from soils have used flux measurements on air-dried soils as a proxy for the COS emission rates of moist soils. However, this method implicitly assumes that COS uptake becomes negligible and COS emission remains steady while soils are drying. We tested this assumption by estimating simultaneously the soil COS sources and sinks and their temperature sensitivity (Q10) from soil-air COS flux measurements on fresh soils at different COS concentrations and two soil temperatures. Measurements were performed on 27 European soils from different biomes and land use types in order to obtain a large range of physical-chemical properties and identify the drivers of COS consumption and production rates. We found that COS production rates from moist and air-dried soils were not significantly different for a given soil and that the COS production rates had Q10 values (3.96 ± 3.94) that were larger and more variable than the Q10 for COS consumption (1.17 ± 0.27). COS production generally contributed less to the net flux that was dominated by gross COS consumption but this contribution of COS production increased rapidly at higher temperature, lower soil moisture and lower COS concentrations. Consequently, measurements at higher COS concentrations (viz. 1000 ppt) always increased the robustness of COS consumption estimates. Across the range of biomes and land use types, COS production rates co-varied with total soil nitrogen (r = 0.68, P < 0.05) and the first-order COS uptake rate co-varied most with microbial N content (r = 0.64, P < 0.05) providing new insights on how to upscale the contribution of soils to the global COS atmospheric budget.
CO2 flux over young and snow-covered Arctic sea ice in winter and spring

Published: January 2018

Abstract. We show that young, snow-covered ice has a potential for sea-ice-to-air CO2 release during winter and spring in the Arctic Ocean north of Svalbard. Young thin sea ice was characterized by high salinities and thus porosity, while the surface of thicker sea ice was relatively warm (> −7.5 °C), due to a thick insulating snow cover, even though air temperatures were as low as −40 °C. During these conditions, brine volume fractions of sea ice were high, providing potentially favorable conditions for gas exchange between sea ice and overlying air even in mid-winter. Although the potential CO2 flux through the sea ice decreased due to the presence of the snow, the snow surface still is a CO2 source to the atmosphere for low snow density and thin snow conditions. Especially young ice formed in leads, without snow cover, is important for the CO2 flux from the ice pack as the fluxes are an order of magnitude higher than for snow-covered older ice.
Seasonal development of iron limitation in the sub-Antarctic zone

Published: January 2018

Abstract. The seasonal and sub-seasonal dynamics of iron availability within the sub-Antarctic zone (SAZ, ~ 40–45° S) play an important role in the distribution, biomass and productivity of the phytoplankton community. The variability in iron availability is due to an interplay between winter entrainment, diapycnal diffusion, storm-driven entrainment, iron scavenging and iron recycling processes. Biological observations utilising grow-out iron addition incubation experiments were performed at different stages of the seasonal cycle within the SAZ to determine the importance of these supply mechanisms. Here we demonstrate that at the beginning of the growing season there is sufficient iron to meet the demands of the phytoplankton community, but as the growing season develops the supply mechanisms fail to meet this demand. Phytoplankton increase their photosynthetic efficiency and net growth rates following iron addition from mid to late summer, with no differences determined during early summer; suggestive of seasonal iron depletion and low iron resupply. The result of which is residual macronutrients at the end of the growing season, and the prevalence of the high-nutrient low-chlorophyll (HNLC) condition. We conclude that despite the prolonged growing season characteristic of the sub-Antarctic zone, which can extend into late summer/early autumn, the results suggest that the iron supply mechanisms are insufficient to maintain potential maximal growth and productivity throughout the season.
Impact of grain size and rock composition on simulated rock weathering
Authors: Israeli Yoni , Emmanuel Simon
Published: January 2018

Abstract. Both chemical and mechanical processes act together to control the weathering rate of rocks. In rocks with micrometer size grains, enhanced dissolution at grain boundaries has been observed to cause the mechanical detachment of particles. However, it remains unclear how important this effect is in rocks with larger grains, and how the overall weathering rate is influenced by the proportion of high and low reactivity mineral phases. Here, we use a numerical model to assess the effect of grain size on chemical weathering and chemo-mechanical grain detachment. As grain size increases, the weathering rate initially decreases; however, beyond a critical size no significant decrease in the rate is observed. This transition occurs when the density of reactive boundaries is less than ~ 20 % of the entire domain. In addition, we examined the weathering rates of rocks containing different proportions of high and low reactivity minerals. We found that as the proportion of low reactivity minerals increases, the weathering rate decreases non-linearly. These simulations indicate that for all compositions, grain detachment contributes more than 36% to the overall weathering rate, with a maximum of ~ 50 % when high and low reactivity minerals are equally abundant in the rock. This occurs because selective dissolution of the high reactivity minerals creates large clusters of low reactivity minerals which then become detached. Our results demonstrate that the balance between chemical and mechanical processes can create complex and non-linear relationships between the weathering rate and lithology.
Developing and exploring a theory for the lateral erosion of bedrock channels for use in landscape evolution models
Authors: Langston Abigail L. , Tucker Gregory E.
Published: January 2018

Abstract. Understanding how a bedrock river erodes its banks laterally is a frontier in geomorphology. Theories for the vertical incision of bedrock channels are widely implemented in the current generation of landscape evolution models. However, in general existing models do not seek to implement the lateral migration of bedrock channel walls. This is problematic, as modeling geomorphic processes such as terrace formation and hillslope–channel coupling depends on the accurate simulation of valley widening. We have developed and implemented a theory for the lateral migration of bedrock channel walls in a catchment-scale landscape evolution model. Two model formulations are presented, one representing the slow process of widening a bedrock canyon and the other representing undercutting, slumping, and rapid downstream sediment transport that occurs in softer bedrock. Model experiments were run with a range of values for bedrock erodibility and tendency towards transport- or detachment-limited behavior and varying magnitudes of sediment flux and water discharge in order to determine the role that each plays in the development of wide bedrock valleys. The results show that this simple, physics-based theory for the lateral erosion of bedrock channels produces bedrock valleys that are many times wider than the grid discretization scale. This theory for the lateral erosion of bedrock channel walls and the numerical implementation of the theory in a catchment-scale landscape evolution model is a significant first step towards understanding the factors that control the rates and spatial extent of wide bedrock valleys.
Frazil-ice growth rate and dynamics in mixed layers and sub-ice-shelf plumes
Authors: Rees Jones David W. , Wells Andrew J.
Published: January 2018

Abstract. The growth of frazil or granular ice is an important mode of ice formation in
the cryosphere. Recent advances have improved our understanding of the
microphysical processes that control the rate of ice-crystal growth when
water is cooled beneath its freezing temperature. These advances suggest that
crystals grow much faster than previously thought. In this paper, we consider
models of a population of ice crystals with different sizes to provide
insight into the treatment of frazil ice in large-scale models. We consider
the role of crystal growth alongside the other physical processes that
determine the dynamics of frazil ice. We apply our model to a simple mixed
layer (such as at the surface of the ocean) and to a buoyant plume under a
floating ice shelf. We provide numerical calculations and scaling arguments
to predict the occurrence of frazil-ice explosions, which we show are
controlled by crystal growth, nucleation, and gravitational removal. Faster
crystal growth, higher secondary nucleation, and slower gravitational removal
make frazil-ice explosions more likely. We identify steady-state crystal size
distributions, which are largely insensitive to crystal growth rate but are
affected by the relative importance of secondary nucleation to gravitational
removal. Finally, we show that the fate of plumes underneath ice shelves is
dramatically affected by frazil-ice dynamics. Differences in the
parameterization of crystal growth and nucleation give rise to radically
different predictions of basal accretion and plume dynamics, and can even
impact whether a plume reaches the end of the ice shelf or intrudes at depth.

Published: January 2018

A alta, em serviços de saúde mental, tem conotação de reabilitação psicossocial e articulação com os dispositivos da rede para promover a atenção continuada no território. Objetivou-se avaliar o processo de alta dos usuários de Centros de Atenção Psicossocial (CAPS). Pesquisa qualitativa e avaliativa, pautada na Avaliação de Quarta Geração. Realizada em um CAPS II de Santa Catarina, com 17 trabalhadores, 14 familiares e cinco usuários, em 2014. Utilizou-se o Método Comparativo Constante para análise dos dados. Compreende-se que o processo de alta é uma importante estratégia de reabilitação psicossocial, promovendo o cuidado no território de vida dos usuários. Este estudo põe em questão a cronificação nos CAPS, pois esses não devem ser serviços que mantenham os usuários em acompanhamento por longo período, mas ser transitórios, possibilitando o fortalecimento do cuidado em outros pontos da rede, estreitando vínculo com a atenção primária e com os demais equipamentos sociais do território.

Actitudes de los españoles ante la eutanasia y el suicidio médico asistido
Authors: Serrano del Rosal Rafael , Heredia Cerro Adrián
Published: January 2018

Este trabajo aborda el proceso de morir y la muerte como un hecho social de primer orden. Sobre dicho proceso y lo que sería una buena muerte existe un ideal socialmente compartido que, en la actualidad, se está en condiciones de alcanzar y del que, sin embargo, la realidad política y jurídica se aleja. En este contexto nos planteamos como objetivos, en primer lugar, medir el apoyo que tienen dos prácticas, como son la eutanasia y el suicidio médico asistido (SMA). En segundo lugar, contrastar si hay diferencias significativas en las opiniones y actitudes de los españoles respecto a su regulación y cuáles son las características sociodemográficas y contextuales que pudieran ayudarnos a explicarlas y, por último, interpretar y discutir los resultados desde una perspectiva sociológica que bebe del republicanismo cívico y la bioética.

Published: January 2018

Este artículo presenta un análisis orientado a identificar la relación entre contactos personales y empleo en una muestra de 250 jóvenes de entre 20 y 34 años en el área metropolitana de Barcelona. El análisis, que se basa en los datos obtenidos en una encuesta de redes personales, muestra que el peso de los contactos en la inserción laboral de los jóvenes es mayor que el señalado en estudios precedentes y que es una característica estructural del mercado de trabajo estudiado. El uso de contactos para acceder al empleo tiene un peso importante antes y durante el periodo de crisis, en categorías profesionales altas y bajas, aunque está asociado a las formas más inestables de empleo. Los resultados señalan que movilizar «pocos» y «buenos» contactos se asocia a la obtención de mejores empleos.
Formas de convivencia de las personas mayores
Authors: López Doblas Juan
Published: January 2018

Este trabajo analiza por qué están cambiando en España las formas de convivencia de las personas mayores. En su planteamiento teórico distingue entre dos realidades básicas: la independencia residencial, propia de quienes comparten un hogar bipersonal con la pareja y de quienes viven en solitario, frente a la convivencia con familiares de otras generaciones. A nivel empírico utiliza una estrategia metodológica cualitativa, cuya técnica de producción de información es el grupo de discusión, y de análisis, la Teoría Fundamentada. La hemos aplicado sobre un perfil específico de actores implicados en este proceso social, las personas mayores que viven solas. Nuestros resultados profundizan en los motivos por los cuales la convivencia intergeneracional no deja de ceder terreno a la independencia residencial.
Futuros climáticos en disputa
Authors: Ramos Torre Ramón
Published: January 2018

Las disputas sobre el Cambio Climático (CC) son disputas sobre el futuro.

En este trabajo se diferencian distintos discursos sobre el CC a los que corresponden distintas maneras de imaginar el futuro. Esas diferencias responden a maneras alternativas de concebir las dimensiones formales y práctico-cognitivas de los horizontes de futuro. Dada la relevancia de las luchas sociales sobre el CC y el enfrentamiento de distintos imaginarios de futuro, se concluye que, lejos del diagnóstico de la presentificación, nos encontramos en una coyuntura en la que prima una futurización en disputa.

The objective of this study is to investigate the significance impact of critical success factors on critical delays in the field of water infrastructure construction projects (WICPs) in the Abu Dhabi emirate in particular. Investigation was conducted utilizing quantitative approach by means of questionnaire survey to examine the understanding of professionals engaged in water infrastructure construction towards several critical success factors influencing critical delays. A total of 323 completed responses from owners, consultants and contractors representatives were gathered against 450 distributed questionnaires.The gathered questionnaires were analysed using an advanced multivariate statistical method of Partial Least Square Structural Equation Modelling (PLS-SEM). Data analysis was conducted in two major phases. The first phase involved a preliminary analysis of the data, to ensure that the data adequately meet the basic assumptions in using SEM. The second phase applied the two stages of SEM. The first stage included the establishment of measurement models for the latent constructs in the research. After confirming the uni-dimensionality, reliability and validity of the constructs in the first stage, the second stage developed to test the research hypotheses through developing the structural models. The results indicated that Project Management Process (PMP), Project Manager’s Competency (PMC), Project Team’s member Competency (PTC), Project Organizational Planning (POP), Project Resources’ Utilization (PRU) and Project Organizational Commitment (POC) had significant positive effects on Critical Delay Factor Evaluation (CDFS). From the results of moderation analysis revealed that Project Benchmark Characteristics (PBC) is positively moderate the effects of Project Management Process (PMP), Project Manager’s Competency (PMC) and Project Team’s member Competency (PTC) and Project Organizational Planning (POP) on Critical Delay Factor Evaluation (CDFS).
La ansiedad por los orígenes. El problema de la historia en la vanguardia literaria de Venezuela
Authors: Alarcón Víctor
Published: January 2018

Este artículo revisa cómo el discurso histórico fue cuestionado por tres autores de vanguardia en Venezuela. En un primer momento, protagonizado por los aportes de Eduardo Blanco y Laureano Vallenilla Lanz, la representación y el estudio de la gesta emancipadora venezolana fueron una indagación fundamental en la cultura. De este modo se organizó la visión de mundo de la sociedad de finales del siglo XIX y se justificó la larga dictadura de Juan Vicente Gómez (1908-1935). Por tanto, la historia se convirtió en un tópico fundamental para las nuevas generaciones de escritores que entraron en juego hacia las décadas 1920 y 1930. José Antonio Ramos Sucre, Arturo Uslar Pietri y Enrique Bernardo Núñez, creadores abordados en este trabajo, cuestionarán las nociones tradicionales con que se leía el pasado venezolano. Se opondrán a las rígidas ideas de hombría, virilidad, familia, progreso y orden, que orientaban los relatos del centro de poder. Así buscarán la manera de abrir la representación y la organización de la realidad, y dar cabida a las nuevas capas sociales que se formaron en la época.
Los sujetos de la H(h)istoria en la novela histórica contemporánea: El seductor de la patria, de Enrique Serna
Authors: Pulido Herráez Begoña
Published: January 2018

El artículo se propone reflexionar sobre el modo como la novela histórica contemporánea parece enfocar en los personajes importantes de la Historia y en su subjetividad (mostrando el acceso a la conciencia mediante la perspectiva interna). Esto podría llevar a considerar que en la novela histórica contemporánea se produce una “subjetivización” de la Historia. Mediante el análisis de la novela El seductor de la patria se relativiza esa subjetivización y se propone que la mirada interna le permite al autor implícito introducir su crítica de la Historia.

Published: January 2018

El presente artículo estudia la lectoescritura patriótica como una biotecnología narrativa que posibilitó el borramiento simbólico de sujetos históricos subalternos, como indios y negros, en la segunda mitad del siglo XIX. Mediante el análisis de tres novelas históricas de Perú, Ecuador y Bolivia, interpretamos la figura del letrado criollo como sujeto de virtud moral comprometido con el proceso independentista, como sujeto interpretativo de la historia y mediador cultural sobre otros grupos sociales, y como sujeto de anagnórisis o revelación personal que ilumina su identidad soterrada y la inscribe en las historias políticas de su tiempo.

Pseudomonas aeruginosa rods are one of the most commonly isolated microorganisms from clinical specimens, usually responsible for nosocomial infections. Antibiotic-resistant P. aeruginosa strains may present reduced expression of virulence factors. This fact may be caused by appropriate genome management to adapt to changing conditions of the hospital environment. Virulence factors genes may be replaced by those crucial to survive, like antimicrobial resistance genes. The aim of this study was to evaluate, using PCR, the occurrence of exoenzyme S-coding gene (exoS) in two distinct groups of P. aeruginosa strains: 83 multidrug-sensitive (MDS) and 65 multidrug-resistant (MDR) isolates. ExoS gene was noted in 72 (48.7%) of the examined strains: 44 (53.0%) MDS and 28 (43.1%) MDR. The observed differences were not statistically significant (p = 0.1505). P. aeruginosa strains virulence is rather determined by the expression regulation of the possessed genes than the difference in genes frequency amongst strains with different antimicrobial susceptibility patterns.

Published: January 2018

Cystadenoma is a rare benign tumor of the salivary glands exhibiting clinical findings very similar to mucocele and, microscopically it may be confused with other lesions such as salivary duct cyst and cheilitis glandularis. It may be classified into two variants: papillary and mucinous, papillary variety being more common than mucinous with very few cases reported in literature. The aim of this work was reporting two cases of oral mucinous cystadenoma, and reviewing the literature regarding clinicopathologic aspects, differential diagnosis and therapeutic management specific to these tumors.

Published: January 2018

The peripheral ossifying fibroma is a non-neoplastic gingival growth classified as a reactive hyperplastic inflammatory lesion. The pathogenesis is unknown. It is an injury that usually affects the anterior region of the maxilla and mandible and has a predilection for women that is most frequently found during the second decade of life. The purpose of this study is to report a case of peripheral ossifying fibroma in a 44-year-old patient with a history of increased volume in the anterior lingual region of the mandible with a 3-year history. Clinically it presented a well-delimited, pediculated lesion with firm and elastic consistency, with pale pink coloration and some erythematous patches. Computed tomography was requested, in which no image of cortical resorption or bone expansion was evidenced, however it was possible to visualize an image that suggested a small bone formation in the region of the lesion. Posteriorly, the patient underwent an excisional biopsy of the lesion. In the findings, the presence of oral mucosa with spindle cell proliferation was verified in the middle of a stromal with osteoid matrix and mature bone production. The treatment was the excision of the lesion with 1 year and 3 months follow-up without relapse.

Introduction: Squamous Cell Carcinoma (SCC) is the most common malignant neoplasm of the oral cavity; however, there is no report in the literature of SCC involved with blue nevus. Case report: We report the case of a patient, a 54-year-old woman who exhibited a brownish spot associated with whitish area, surrounded by a hyperemic area in the soft palate. After an incisional biopsy and histopathological analysis, the presence of invasive squamous cell carcinoma was shown, in addition, in other fragment, to the presence of fusiform cells disposed parallel to the epithelium, exhibiting intense brownish cytoplasmic pigments. Immunohistologically, the neoplastic epithelial cells demonstrated intense immunoexpression for the anti-pan Cytokeratin antibody, while the fusiform cells showed strong immunopositivity for the anti-S-100 and anti-Melan-A antibodies, and weak immunomarking for anti-HMB-45. Based on the microscopic findings described, the final diagnosis was Oral Squamous Cell Carcinoma (OSCC) involving a blue cell nevus. Conclusion: Therefore, we sought to relate the first case of involvement of OSCC and blue cell nevus, up to the present time.

Introduction: The ozone therapy is a bio-oxidation therapy, based on a gaseous mixture with oxygen and ozone. It can be considered an alternative therapeutic tool the treat- ment of many systemic and locals diseases. It induces acute oxygenation stress and is not deleterious, which allows the restoration of oxidation and reduction balance. Within the therapeutic effects, it has been associated to the improvement metabolism and the peripheral tissue oxygenation. In addition, ozone is an important antimicrobial agent against bacteria, fungi, protozoa and viruses. In Dentistry, the ozone therapy has been used in several clinical situations due to its mechanisms of action. Objectives: The pur- pose of this literature review is to discuss the chemical and physical properties of ozone and its mechanisms of action in tissue repair. Methods: It is a narrative review based on research articles searched in Pubmed and LILACS database, from December 2015 to May 2016. The following descriptors in English: “ozone”, “oxidative stress” and “tissue repair” used. Finally, 36 articles were included in this narrative literature review. Results and Conclusion: The use of ozone as treatment seems to be promising in health areas, including dentistry due to its biological and biochemical properties. However, there is a need for more methodologically adequate studies so it can be safely and efficiently applied.

Introduction: Verruciform xanthoma (VX) is a reactive oral mucosal lesion that can re- semble other papillary conditions. Objective: To report a case of gingival VX clinically mimicking other papillary swellings. Case report: A 66-year-old female presented for evaluation of a painless papillary growth in the gingival margin of the upper right central incisor. Clinical diagnosis included papillary gingival hyperplasia and VX. An excisional biopsy was done and histology revealed a proliferative surface epithelium with papillary projections and CD68+ xanthomatous cells on the upper papillary superficial connective tissue. Diagnosis was VX and the patient remains in clinical follow-up with no signs of recurrence for 4 months. Conclusion: VX should be considered in the differential diagnosis of gingival papillary swellings.

Introduction: Melanoma is an aggressive malignant neoplasm of uncertain etiology. Al- though the third most common skin cancer, melanoma is rare in the oral cavity, accounting for less than 1% of all melanomas and for 0.5% of all malignant oral tumors. Objective: This study reports a case of melanoma diagnosed and followed up by the dentistry team of the Napoleão Laureano Hospital, João Pessoa, Paraíba, Brazil. Case report: A 69-year- -old dark-skinned male patient was referred to the stomatology service of the hospital reporting pain and bleeding in the upper alveolar ridge, as well as the presence of a “lump” at the same site. Intraoral physical examination revealed a purple nodule of soft consistency in the anterior maxilla, which measured 2.0 cm in diameter and exhibited superficial ulcerations. An incisional biopsy was performed and histopathological analysis revealed intense proliferation of atypical melanocytes characterized by variable degrees of pleomorphism and nuclear hyperchromatism. The diagnosis was melanoma of the oral mucosa. The patient underwent surgical resection consisting of complete removal of the tumor with wide safety margins, chemotherapy, and adjuvant radiotherapy. The patient continues under follow-up and showed no recurrence of the lesion one year after surgery. Conclusion: Melanoma of the oral mucosa exhibits an aggressive behavior and rapid gro- wth, as observed in the present case. Knowledge of the clinical and etiopathogenic features is important for the early diagnosis of the disease in order to improve patient survival.

Antral pseudocysts of the maxillary sinus are the second most common lesions in the maxillary sinus region. The aim of this study was to analyze the frequency of antral pseudocysts of the maxillary sinus diagnosed with panoramic radiographs, cone beam computed tomography and a clinical questionnaire. This was a cross-sectional study in- volving patients of a private radiology institute. A total of 185 panoramic radiographs with images suggestive of antral pseudocysts were selected out of 6,000. The patients were invited to attend the service and 28 were selected for this study. Panoramic radio- graphs were obtained and, when the image was suggestive of antral pseudocysts, the patient was invited to undergo cone beam computed tomography and to answer a clinical questionnaire. The control group consisted of 30 patients without antral pseudocysts on panoramic radiographs who had undergone cone beam computed tomography and who had filled out the clinical questionnaire. Pearson’s chi-square test and Fisher’s exact test were used to determine differences in the frequency of the variables among study groups, adopting a p value of 0.05 and a 95% confidence interval. The relationship between cone beam computed tomography and the diagnosis of antral pseudocysts, and with the data collected with the clinical questionnaire was established. A statistically significant difference was found regarding atrophy of the turbinates and obstruction of the meatal ostium. In addition, patients with antral pseudocysts had significantly more histories of allergy, allergy persistence, and use of topical nasal medication compared to the control group, as well as nasal obstruction, thick nasal discharge, a runny nose and postnasal drip. The use of topical nasal medication and the presence of atrophy of the turbinates and obstruction of the meatal ostium suggest a relationship with the occurrence and persistence of antral pseudocysts.

Introduction: Cardiovascular diseases and stroke in particular are the leading causes of death worldwide. The most common reason for this interruption is a buildup of fatty deposits on the inner walls of blood vessels; upon calcification, these deposits are termed atheromas. Objective: The aim of this study was to identify calcified atherosclerotic plaque- -like soft tissue calcifications in obese subjects using panoramic radiography. Materials and Methods: Sixty-three obese patients undergoing digital panoramic radiography in a radiology clinic in Belo Horizonte, Brazil, were selected and diagnosed with grade II obesity with comorbidities and grade III obesity according to the World Health Organiza- tion (WHO) body mass index (BMI) score table. The radiographs were examined by two trained oral and maxillofacial radiologists, and their evaluations were analyzed using the kappa test. Statistical analysis was performed using the X2 test, and the odds ratio was determined with a 95% confidence interval. A 5% significance level was used. Results: The weight and BMI (p < 0.01) differed significantly between individuals in the grade II with comorbidities and grade III groups, but no difference was observed for age and height. Of 63 radiographs, 45 (71.42%) showed calcifications in the cervical region, with no statistically significant difference between the grade II and grade III groups. Neither gender nor side was significantly correlated with the presence of soft tissue calcification. Conclusion: This study demonstrates the importance of panoramic radiography in iden- tifying calcified atheromatous plaques. Such images may have critical diagnostic value for the early detection of carotid artery atheromas in obese subjects and thus may contribute to an increase in the length and quality of life of such individuals.
