Context-specific information, including differences in geographical areas, such as distinct altitudes, can be important to explain variations in physical growth. We aimed to compare the estimation of maximum growth velocity and pubertal growth-spurt parameters of children and adolescents living at low and moderate altitudes in Colombia. A cross-sectional study, including a representative cohort of 30.305 (51% boys) children and adolescents aged 1–18 years from Colombia, was performed. The heights were measured with standardized techniques. The Preece–Baines growth model was used to estimate the mathematical and biological parameters of the height-growth velocities and growth spurts for both sexes. The altitudes were categorized as low (18 to 564 m above sea level) or moderate (2420 to 2640 m above sea level). There were no differences in final height (h₁), peak height velocity size (h_θ), age at peak height velocity (APHV), or peak height velocity PHV (cm/y) between the subjects living in both altitudes (p > 0.05). The APHV was estimated at 12.75 ± 0.75 years in the boys and at 10.05 ± 0.65 years in the girls. The girls reached the APVH 2.70 years earlier than the boys. Regarding the PHV, the boys reached higher growth velocity, which was 6.85 ± 0.55 cm/y. In conclusion, there were no significant differences in final height, peak height, APHV, or PHV between the children and adolescents living at distinct altitudes in Colombia. The PHV occurred approximately 3 years earlier in the girls than in the boys. Furthermore, the girls’ estimated PHV, APHV, and final height were lower than those of the boys. This study allows additional insight into pubertal growth-spurt parameters and also provides a valuable reference database for the assessment of Colombian children and adolescents. Full article

I compare the status of a sacred language in two very different religious traditions. In Judaism, the Hebrew language is the language of liturgy, prayer, and the Written Law. The traditional way of reading Torah passages involved translating them into Aramaic, the everyday language of communication in the Middle East in the first half of the first millennium CE. Later, other Jewish languages, such as Yiddish, played a role similar to that of Aramaic in the Talmudic period, constituting a system referred to as the “Traditional Jewish Bilingualism”. Hebrew lexemes had denotations related to the realm of Biblical texts, while Aramaic/Yiddish lexemes had everyday references. Therefore, the act of translation connected the two realms or domains. The Lucumí (Santería) Afro-Cuban religion is a syncretic tradition combining Roman Catholicism with the Ifá tradition, which does not have a corpus of written sacred texts, however, it has its sacred language, the Lucumí (Anagó) language related to the Yoruba language of West Africa. While the Spanish-Lucumí bilingualism plays an important role in Santería rituals, the mechanisms of reference are very different from those of the Hebrew-Yiddish bilingualism in Judaism. In Santería, divinations about the meaning of Lucumí words play a role similar to the translations from Hebrew in Judaism. I further discuss the role of ritual dances in Santería for the transition from the sacred to the secular domain and a function of Hebrew epitaphs to connect the ideal world of Hebrew sacred texts to the everyday life of a Jewish community.

The biopreservation of meat products is of great interest due to the demand for products with low or minimal chemical additives. Lactic acid bacteria (LAB) have been used as protective cultures for many centuries. The objective of this work was to characterize 10 native LAB isolated from meat masses with biopreservative potential for meat products. The isolates were subjected to viability tests with different concentrations of NaCl, nitrite, and nitrate salts, pHs, and temperature conditions. Antibiotic resistance and type of lactic acid isomer were tested. In addition, the isolates were tested against seven pathogens, and inhibitory substances were identified by diffusion in agar wells. Finally, two isolates, Lb. plantarum (SB17) and Lb. sakei (SB3) were tested as protective cultures of chorizo in a model. As a result, the viability at different concentrations of NaCl and nitrate and nitrate salts were obtained. pH and temperature exerted a negative effect on the growth of some of the isolates. Pathogens were inhibited mainly by the presence of organic acids; P. aurius was the most susceptible, and S. typhimurium and S. marcescens were the most resistant. The strains SB17 and SB3 had similar effects on chorizo, and time exerted a deleterious effect on microbiological quality and pH. The results indicated that the 10 isolates show promising characteristics for the preservation of cooked meat products, with the strain Lb. plantarum (SB17) being the most promising. Full article
