What is a traditional food? Conceptual evolution from four dimensions
Rocillo-Aquino Zeltzin,Cervantes-Escoto Fernando,Leos-Rodríguez Juan Antonio,Cruz-Delgado Daniela,Espinoza-Ortega Angélica 한국식품연구원 2021 Journal of Ethnic Foods Vol.8 No.-
The purpose was to specify the concept of traditional food and the dimensions that make it up, identifying: definitions, authors and research projects; as well as to determine what is known and possible topics for future research. A literature review of traditional foods was conducted that examined the conceptual development of the term. Social network analysis (SNA) was also used to identify the most relevant definitions and working groups on the topic. Twenty-three definitions were identified in the period 1995–2019. It reveals the difficulty of establishing one that ecompasses such a dynamic concept. Although there is variability in the specific characteristics of these foods, four dimensions have been established: time, place, know-how, and cultural meaning. It was found that their main characteristic is the transmission of knowledge and raw materials between generations. The conceptualization of the term has been developed mainly in Europe, based on the perspective of consumers. New trends in research include the contrast and complementarity of innovation in traditional foods and the difference between these products and those named with similar attributes such as typical, regional, ethnic, local, among others. Social network analysis (SNA) was used to study the definitions of a concept, something that had not been done with this approach. Suggestions are made for possible research on the subject, such as the conceptual delimitation of related terms and the compatibility between innovation and tradition.

Background: Chronic myeloid leukemia (CML) is one of the most frequent hematopoietic malignancies in the elderly population; however, knowledge is limited regarding the genetic factors associated with increased risk for CML. Polymorphisms affecting microRNA (miRNA) biogenesis or mRNA:miRNA interactions are important risk factors in the development of different types of cancer. Thus, we carried out a case-control study to test the association with CML susceptibility of gene variants located in the miRNA machinery genes AGO1 (rs636832) and GEMIN4 (rs2740348), as well as in the miRNA binding sites of the genes BRCA1 (rs799917) and KRAS (rs61764370). Materials and Methods: We determined the genotype of 781 Mexican-Mestizo individuals (469 healthy subjects and 312 CML cases) for the four polymorphisms using TaqMan probes to test the association with CML susceptibility. Results: We found a borderline association of the minor homozygote genotype of the KRAS_rs61764370 polymorphism with an increased risk for CML susceptibility (P = 0.06). After gender stratification, this association was significant only for women (odds ratio [OR] = 13.41, P = 0.04). The distribution of the allelic and genotypic frequencies of the four studied SNPs was neither associated with advanced phases of CML nor treatment response. Conclusions: To the best of our knowledge, this study is the first to show a significant association of the KRAS_rs61764370 SNP with CML. To further determine such an association of with CML susceptibility, our results must be replicated in different ethnic groups.
