Background: To describe the epidemiology and clinical characteristics of migraine and the status of treatment in Colombia. Additionally, the use of health resources by patients was measured.
Methods: This was a non-interventional, retrospective, descriptive study conducted in one Colombian Health Management Organization (HMO) from 2018 to 2022 with a follow-up period of 5 years.
Introduction: Radiographs are still widely used, underestimating the risks. This situation is frequent in neonatal care units, generating radiation doses than in adults.
Objective: To quantify the received radiation doses when performing radiographs on neonates and the possible factors associated with higher doses.
Cassava is a staple food used in many countries around the world, despite deficiencies in micronutrients such as provitamin A carotenoids. Unfortunately, improvement of the cassava nutritional content by use of conventional breeding is slow and difficult. Therefore, there is an urgent need to develop and standardize protocols using biotechnological tools to improve cassava.

- * The study focuses on the ORANGE protein (OR), which helps boost carotenoid accumulation, and its interaction with phytoene synthase (PSY), critical for carotenoid biosynthesis.
- * Findings indicate that yellow cassava varieties have higher OR protein levels and that manipulating gene expression in cassava embryogenic callus can significantly enhance carotenoid accumulation.
