Initial pig developmental stage influences intestinal organoid growth but not cellular composition.

Background: Intestinal organoids are promising tools in the context of animal experiment reduction but a thorough characterization of the impact of the origin of intestinal stem cells (ISC) on organoid phenotype is needed to routinely use this cellular model. Our objective was to evaluate the effect of ISC donor age on the growth, morphology and cellular composition of intestinal organoids derived from pig.

Methods: Organoids were derived from jejunal and colonic ISC obtained from 1-, 7-, 28-, 36- and 180-day-old pigs and passaged three times.

[Revue systématique des tests cognitifs validés et/ou ayant des normes de référence pour la population canadienne francophone âgée].

Il est essentiel d'utiliser des tests cognitifs ayant été validés et détenant des normes de référence auprès de la population cible, puisque les réalités culturelles et linguistiques différentes entre l'échantillon de validation ou auprès duquel les normes ont été créées et la population cible peuvent affecter les résultats. Cette revue systématique vise à recenser et décrire les tests cognitifs (incluant tests, questionnaires et grilles d'observation) validés et/ou présentant des normes sur la population âgée canadienne francophone. Au total, 46 articles ont été sélectionnés.

Lessons from a large nationwide cohort of 350 children with ovarian mature teratoma: A study in favor of ovarian-sparing surgery.

Background: Ovarian mature teratoma (OMT) is a common ovarian tumor found in the pediatric population. In 10%-20% of cases, OMT occurs as multiple synchronous or metachronous lesions on ipsi- or contralateral ovaries. Ovarian-sparing surgery (OSS) is recommended to preserve fertility, but total oophorectomy (TO) is still performed.

Unresectable thoracic neuroblastic tumors: Changes in image-defined risk factors after chemotherapy and impact on surgical management.

Purpose: Neuroblastoma management in children is multimodal and depends on multiple factors, including the possibility of complete surgical resection. Image-defined risk factors (IDRFs) are used to assess the feasibility of primary surgery. We studied the changes in IDRFs after neoadjuvant chemotherapy for thoracic neurogenic tumors.

[The disability adviser, an important member of the training team].

Disability advisers work in companies and training centres. They are real resource people for learners with a disability. They are there to answer all their questions, favour their integration and ensure their training is a success.
