Quinoa in Ecuador: Recent Advances under Global Expansion

Quinoa is a highly diverse crop domesticated in the Andean region of South America with broad adaptation to a wide range of marginal environments. Quinoa has garnered interest worldwide due to its nutritional and health benefits. Over the last decade, quinoa production has expanded outside of the Andean region, prompting multiple studies investigating the potential for quinoa cultivation in novel environments. Currently, quinoa is grown in countries spanning five continents, including North America, Europe, Asia, Africa, and Oceania. Here, we update the advances of quinoa research in Ecuador across different topics, including (a) current quinoa production situation with a focus on breeding progress, (b) traditional seed production, and (c) the impact of the work of the nongovernment organization “European Committee for Training and Agriculture” with quinoa farmers in Chimborazo province. Additionally, we discuss genetic diversity, primary pests and diseases, actions for adapting quinoa to tropical areas, and recent innovations in quinoa processing in Ecuador. Finally, we report a case study describing a participatory breeding project between Washington State University and the Association of Andean Seed and Nutritional Food Producers Mushuk Yuyay in the province of Cañar

Harvey Cushing: early use of tendon transfers for repair of foot deformity: A historical case report

We describe 4 cases of tendon transfers for correction of foot deformities, which were performed by Harvey Cushing in 1898

K-shell photoionization of ground-state Li-like carbon ions [C3+^{3+}]: experiment, theory and comparison with time-reversed photorecombination

Absolute cross sections for the K-shell photoionization of ground-state Li-like carbon [C$^{3+}$(1s$^2$2s $^2$S)] ions were measured by employing the ion-photon merged-beams technique at the Advanced Light Source. The energy ranges 299.8--300.15 eV, 303.29--303.58 eV and 335.61--337.57 eV of the [1s(2s2p)$^3$P]$^2$P, [1s(2s2p)$^1$P]$^2$P and [(1s2s)$^3$S 3p]$^2$P resonances, respectively, were investigated using resolving powers of up to 6000. The autoionization linewidth of the [1s(2s2p)$^1$P]$^2$P resonance was measured to be $27 \pm 5$ meV and compares favourably with a theoretical result of 26 meV obtained from the intermediate coupling R-Matrix method. The present photoionization cross section results are compared with the outcome from photorecombination measurements by employing the principle of detailed balance.Comment: 3 figures and 2 table

Quemerina, omentina-1 y miR-103p y su relación con la diabetes mellitus gestacional

Diversos genes pueden desencadenar la diabetes mellitus gestacional (DMG), considerada como un problema de salud pública de etiología compleja y multifactorial. Objetivo: presentar una revisión de tema de la evidencia científica disponible sobre el impacto de la expresión de los genes omentina-1, quemerina y miR-1013p, implicados en el desarrollo de la DMG. Materiales y métodos: se realizó una búsqueda de estudios electrónicos transversales a través de la base de datos registrados en MEDLINE y PUBMED, publicados durante 2010-2019, que valoraran mediciones de los tres genes en mujeres con DMG. Resultados: ocho artículos cumplieron con los criterios de inclusión, cuatro artículos midieron los niveles de quemerina, tres de omentina-1 y uno de miR-103p. Entre los niveles de quemerina se mostró que la circulación de quemerina y miR103p se correlacionó positivamente con las variables metabólicas durante el primer y tercer trimestre del embarazo. Se demostró que la liberación de omentina-1 fue mayor en el tejido adiposo vs. placenta cuando se presenta obesidad. Conclusión: la expresión de genes y la presencia de obesidad están relacionados con el desarrollo de la diabetes mellitus gestacional
