        Benign osteoblastoma of the mandible: a case report

        María del Carmen Navas-Aparicio(María del Carmen Navas-Aparicio ) 대한구강악안면외과학회 2023 대한구강악안면외과학회지 Vol.49 No.1

        Osteoblastoma is a rare benign neoplasm formed by osteoid tissue and well-vascularized bone that occurs mainly in children and adolescents. It appears primarily in the long bones, vertebral column, and small bones of the hands and feet, and not typically in the skull and maxillary bones. The purpose of this study is to present the case of an 8-year-old girl with a diagnosis of right mandibular osteoblastoma and a review of the relevant literature. The goals of treatment were to preserve dental occlusion, masticatory function and facial symmetry while minimizing the effects on patient body image and quality of life. Osteoblastoma, although it is benign, can be aggressive, and its treatment will depend on the timing of diagnosis, size and location. Early diagnosis is essential to avoid not only radical surgery as in the case presented, but also to help minimize the risk of possible relapse and potential malignancy of a benign osteoblastoma.

        Effect of Seasonal Variations and Collection Form on Antioxidant Activity of Propolis from San Juan, Argentina

        María I. Isla,Iris C. Zampini,Roxana M. Ordóñez,Soledad Cuello,Belén Carrasco Juárez,Jorge Esteban Sayago,María I. Nieva Moreno,María Rosa Alberto,Nancy R. Vera,Enrique Bedascarrasbure,Alejandro Alvar 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.6

        Propolis was included in the Argentine Food Code as a functional food. The chemical parameters and antioxidant properties of propolis samples from the same colonies of Apis mellifera in San Juan (Cuyo region, Western Argentine) were compared every month for 1 year using two collection methods. Chemical parameters were analyzed by the spectrophotometric method and fingerprinting using high-performance liquid chromatography with ultraviolet detection. The antioxidant activities of propolis samples were measured using model systems including the analysis of the scavenging activities for 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and the β-carotene bleaching assay. The results showed that propolis had a higher free radical scavenging and lipid peroxidation inhibitory capacity than butylated hydroxytoluene and quercetin, antioxidants used in the pharmaceutical and food industries. The concentration required to scavenge 50% of free radicals (SC50) values differed depending on the sample collection month. Samples collected in November had the highest antioxidant capacity. In all cases, SC50 values of propolis samples obtained by scraping were similar to those collected from a wire mesh (5μg/mL for ABTS and 20–30μg/mL for DPPH radicals). A significant positive correlation was found between the antioxidant capacity and flavonoid content of each analyzed extract. The chemical profiles were very similar. Galangin (3,5,7-trihydroxyflavone), an antioxidant compound, was detected in all samples as a major compound. The chromatographic profile suggests that of Baccharis sp., which would be one of the botanical sources of propolis from western Argentina, and the content of galangin can be used as a parameter for evaluating propolis quality. Our results suggest that Argentine propolis from Cuyo is a promising source of bioactive compounds as ingredients for developing functional foods with a beneficial impact on oxidative stress.

        Jazyk písomností Slovákov na dolnej zemi: na príklade slovenského vojvodinského evanjelického cirkevného zboru a. v. Kysáč v rokoch 1773 – 1918

        Daniela Marčoková(Daniela Marčoková ),Jasna Uhláriková(Jasna Uhláriková ) 한국슬라브어학회 2022 슬라브어연구 Vol.27 No.2

        Mass migrations of Slovaks from the north of Hungary to the south (to the Lowland) in the 18th and 19th centuries are part of the migration of serfs as part of the systematic colonization of Empress Maria Theresa after the expulsion of the Turks from this territory. Coexistence with other nations or old settlers, as well as state politics, naturally influenced further development and determined the life of immigrants in national, cultural, economic, social, as well as linguistic terms. The aim of this paper is to present the linguistic situation of the Slovaks in the settlement of Kysáč in today's Serbia based on church documents from their immigration to the end of the First World War. We examined the chronicle of the Kysáč priest František Jesenský from 1773, registers from the years 1787 – 1918, the minutes of the canonical visitation of the Kysáč church choir from 1835, the minutes of the school board of the Kysáč school from the years 1895 – 1915, the minutes of the presbytery conventions 1912 – 1916 and other documents of the church archive of the Slovak Evangelical Church a. c. in Kysáč.

        Representations of cultural diversity in music education textbooks: a critical and comparative analysis

        Bernabé Villodre María del Mar,Azorín-Delegido José Manuel,Martínez-Bello Vladimir 한국다문화교육학회 2024 Multicultural Education Review Vol.16 No.1

        Spain is one of the European countries that attracts the most immigration, and the Valencian and Murcian regions have a large immigrant population. To our knowledge, no studies have analysed the representation of cultural diversity in visual representations of the body and musical practices in their music textbooks. Therefore, the main objective of this research is to describe the representation of cultural diversity in Spanish music textbooks from a critical and comparative perspective that analyses visual representations of the body and its interactions with the main musical processes. The results show a greater presence of students with white European features, as well as certain cultural stereotypes perpetuated by visual representation with musical instruments. Thus, although a greater variety of human types can be observed in the graphic representations of music textbooks, these take a reductionist and simplistic view of cultural diversity.

        Work Ability Index: Psychometric Testing in Aeronautical Industry Workers

        González-Domínguez María Eugenia,Fernández-García Elena,Paloma-Castro Olga,González-López Regina María,Rivas Pérez María Paz,López-Molina Luis,García-Jiménez Jesús,Romero-Sánchez José Manuel 한국산업안전보건공단 산업안전보건연구원 2024 Safety and health at work Vol.15 No.1

        Background The Work Ability Index (WAI) is an instrument that measures work ability. The wide dispersion of the WAI internationally has led to its adaptation for use in different countries. This study aimed to evaluate the psychometric properties of the Spanish version of the WAI. Methods A methodological design was used over an opportunistic sample of 233 workers in the aeronautical industry in Spain. Reliability was evaluated through internal consistency. Factorial validity, known groups, and convergent validity were tested. Results The Cronbach's alpha and item-total correlation indicated an adequate internal consistency. The confirmatory factor analysis, performed to evaluate the factorial validity, found adequate fit indices for a two-factor solution with a high correlation between the factors. Factor 1, “Subjectively estimated work ability and resources”, was composed of 3 subscales and factor 2, “Ill-health-related”, of 2 subscales. Subscales 4 and 6 had loading in both factors. Workers under 45 years of age obtained higher significant scores than older ones. Convergent validity was also evidenced since WAI was highly correlated with self-assessment of health status. Conclusions The Spanish version of the WAI has shown evidence of reliability and validity in this study, supporting its use in individual and collective health surveillance by occupational health professionals. The factorial solution that was found has previously been reported in another international context. However, further research is needed to resolve the discrepancies detected in the role of some subscales between other national and international studies.

        A Girl with 15q Overgrowth Syndrome and dup(15)(q24q26.3) that Included Telomeric Sequences

        María de los Ángeles Gutiérrez-Franco,María de la Luz Madariaga-Campos,Ana I. Vásquez-Velásquez,Esmeralda Matute,Roberto Guevara-Yáñez,Horacio Rivera 대한진단검사의학회 2010 Annals of Laboratory Medicine Vol.30 No.3

        Distal 15q trisomy or tetrasomy is associated with a characteristic phenotype that includes mild to moderate intellectual disability, abnormal behavior, speech impairment, overgrowth, hyperlaxity, long face, prominent nose, puffy cheeks, pointed chin, small ears, and hand anomalies (mainly arachno- and camptodactyly). We present the case of a 13-yr-old girl with the main clinical features of 15q overgrowth syndrome and a 46,XX,dup(15)(q24q26.3)[117]/46,XX[3].ish dup(15)(q24q26.3) (SNPRN+,PML+,subtel++,tel++) de novo karyotype. The findings in this case are consistent with those in the previous distal 15q trisomy cases that presented with overgrowth and mental retardation. Further, the rearranged chromosome had a double set of directly oriented telomeric and subtelomeric sequences. (Korean J Lab Med 2010;30:318-24)

        Functions attaining the supremum and isomorphic properties of a Banach space

        Mar\'{\i}a D. Acosta,Julio Becerra Guerrero,Manuel Ruiz 대한수학회 2004 대한수학회지 Vol.41 No.1

        We prove that a Banach space that is convex-transitive and such that for some element u in the unit sphere, and for every subspace M containing u, it happens that the subset of norm attaining functionals on M is second Baire category in M∗ is, in fact, almost-transitive and superreflexive. We also obtain a characterization of finite-dimensional spaces in terms of functions that attain their supremum: a Banach space is finite-dimensional if, for every equivalent norm, every rank-one operator attains its numerical radius. Finally, we describe the subset of norm attaining functionals on a space isomorphic to 1, where the norm is the restriction of a Luxembourg norm on L1. In fact, the subset of norm attaining functionals for this norm coincides with the subset of norm attaining functionals for the usual norm.

        D-003 and Warfarin Interaction on the Bleeding Time and Venous Thrombosis Experimentally Induced in Rats

        Mar? Lourdes Arruzazabala,Vivian Molina,Daisy Carbajal,Rosa M? 한국식품영양과학회 2004 Journal of medicinal food Vol.7 No.2

        D-003 is a mixture of higher aliphatic primary acids isolated and purified from sugarcane wax, the main component of which is octacosanoic acid. D-003 exhibits a cholesterol-lowering effect as well as antiplatelet and antithrombotic effects in experimental models. Warfarin is a coumarin derivative with anticoagulant activity that acts as a vitamin K antagonist. Since in clinical practice warfarin and D-003 could be administered together, the objective of this study was to evaluate the effects of the simultaneous administration of both drugs on the bleeding time and the venous thrombosis experimentally induced in rats. The combined therapy of minimally effective doses of D-003 and warfarin produced an antithrombotic effect significantly higher than those produced by each monotherapy. Likewise, the prolongation of bleeding time induced by warfarin was increased by the simultaneous administration with D-003, showing a synergistic effect between both drugs.
