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.

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.

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

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.

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.

Diaspora, A Way of Initiation

Marí,a Jesú,s De Prada Vicente 건국대학교 아시아·디아스포라 연구소 2015 International Journal of Diaspora&Cultural Critici Vol.5 No.1

Nowadays, the term “diaspora” is used for any ethnical dispersion forced or not. This tendency is due to recent Diaspora Studies, whose remote origin may be found in Jewish nationalism born in the late 19th century. But Jewish nationalism realized in the nation-state of Israel is opposite to the idea of diaspora. For diaspora is beyond nation, beyond nationalism. Following Armand Abécassis, a French philosopher, the true meaning of the term should be found in Genesis, especially in Abraham’s exile ordered by God. The story of God and Abraham shows that diaspora is not a physical movement but a spiritual one. It implies the discovery of one’s individual self and necessity to be in collectivity, sharing things and thoughts with others. Now, if diaspora means discovery of one’s individual self and sharing with others in collectivity, this may prove to be contradictory. Indeed, the apparent contradiction is included in diaspora. The Jew in diaspora proves to be and not to be simultaneously.

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

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)

PERCEPCIONES DE LOS ACADÉMICOS SOBRE LA TRANSFERENCIA DE CONOCIMIENTOS A LAS EMPRESAS EN LA ARGENTINA

María Fernanda Arias. Institute of Iberoamerican Studies Pusan Universit 2012 International Journal of Latin American Studies Vol.2 No.2

Resumen. El presente estudio trata de develar las representaciones sociales1 de los funcionarios de las universidades argentinas acerca de su contribución con el mundo productivo a través de la transferencia de conocimientos. La revolución científica y tecnológica que comenzó hacia los años 50 del siglo pasado se profundizó en el tiempo y el conocimiento pasó a reemplazar al capital como generador de riqueza. Consecuentemente, las universidades contribuyeron cada vez más en el mundo desarrollado a avanzar en la producción de nuevos bienes y servicios. Sin embargo, la producción científico-tecnológica continúa concentrada en los países desarrollados y América Latina y en ella, la Argentina, contribuye muy escasamente en la generación de conocimientos innovativos. La respuesta a esta problemática es generar una relación estrecha entre la universidad, la empresa y el estado para coordinar conjuntamente la política científico-tecnológica de los países. Sin embargo, de acuerdo a los consultados, esta receta que ha tenido buena acogida dentro de los países desarrollados, no se ha implantado de la misma manera en Argentina. Abstract. The present study tries to unveil social representations of argentine universities’ officials about their contribution to the productive world through transfer of knowledge. The scientific and technological revolution that began around the middle of last century deepened over time and knowledge replaced capital as a generator of wealth. As a result, universities contributed increasingly in the developed world to make progress in the production of new goods and services. However, the scientific-technological production remains concentrated in developed countries and Latin America and in it, Argentina, contributes very sparsely in the generation of innovative knowledge. The solution to this problem is to create a close relationship between University, Companies and State to jointly coordinate the scientific-technological policy of countries. However, according to respondents, this recipe which has been successfully installed in developed world has not yet been adopted in Argentina.

Variabilidad y Sistematicidad en los Mecanismos de Traslación Temporal del Discurso Directo e Indirecto de Aprendientes de ELE Coreanos

María Victoria Soulé 부산외국어대학교 이베로아메리카연구소 2014 이베로아메리카 Vol.16 No.2

This study examines the reporting temporal mechanisms implemented by Korean learners of Spanish L2 through direct and indirect speech. In order to obtain the necessary information a corpus consisted of nine oral narratives of university students of Spanish is being analysed. These students belong to the B1, B2 and B2+ levels of the Common European Framework of Reference. The results acknowledge that from the first levels, learners are capable of employing the structures related to the two discourse types. Regarding the indirect speech, the interlanguage of the participants behaves systematically in the temporality of the regent verb; however, the temporality of the reproduced sequences varies according to the learners’ level. On the other hand, even though the construction of the direct speech shows a larger variability, it also is possible to observe a certain degree of systematicity in the use of this kind of discourse as an internal evaluation device. Key Words: Reporting Mechanisms, Direct and Indirect Speech, Temporal Deixis, Verbal Temporality, Spanish L2 <Resumen> En este trabajo se examinan los mecanismos de traslación temporal que llevan a cabo aprendientes de ELE coreanos a través del discurso directo e indirecto. Para ello se analiza un corpus constituido por nueve narraciones orales de estudiantes universitarios del grado en Estudios Hispánicos, dichos estudiantes pertenecen a los niveles B1 y B2+ del Marco común europeo de referencia. Los datos obtenidos revelan que desde los primeros niveles los aprendientes son capaces de emplear estructuras de los dos tipos de discurso. Por lo que respecta al discurso indirecto, la interlengua de los participantes se comporta de forma sistemática en cuanto a la temporalidad del verbo regente; sin embargo, la temporalidad de las secuencias reproducidas varía en función del nivel de los aprendientes. Por otra parte, aunque la conformación del discurso directo presenta una mayor variabilidad en el uso de la morfología verbal, es posible observar cierto grado de sistematicidad en la utilización de este tipo de discurso como un mecanismo de evaluación interna.
