Mapping food system drivers of the double burden of malnutrition using community-based system dynamics: a case study in Peru.

Background: Peru is facing a double burden of malnutrition (DBM), characterized by the co-existence of undernutrition and overnutrition. Double-duty actions that concurrently target common drivers of undernutrition and overnutrition, while ensuring no unintended side effects, are recommended to effectively address the DBM. To understand these complex common mechanisms and design context-specific double-duty actions, there is a need for participatory systems approaches.

The role of early temperament on oral language development of New Zealand children speaking Mandarin or Cantonese.

This study investigated the role of temperament in oral language development in over 200 Mandarin and Cantonese speakers in the pre-birth longitudinal cohort study. Mothers assessed infant temperament at nine months using a five-factor Infant Behaviour Questionnaire-Revised Very Short Form. They also reported on children's vocabulary and word combinations at age two using adapted MacArthur-Bates Communicative Development Inventory short forms.

TASOR expression in naive embryonic stem cells safeguards their developmental potential.

The seamless transition through stages of pluripotency relies on a balance between transcription factor networks and epigenetic mechanisms. Here, we reveal the crucial role of the transgene activation suppressor (TASOR), a component of the human silencing hub (HUSH) complex, in maintaining cell viability during the transition from naive to primed pluripotency. TASOR loss in naive pluripotent stem cells (PSCs) triggers replication stress, disrupts H3K9me3 heterochromatin, and impairs silencing of LINE-1 (L1) transposable elements, with more severe effects in primed PSCs.
