Severe hypertransaminasemia during mild SARS-CoV-2 infection: A pediatric case report and literature review.

Introduction: Liver injury during SARS-CoV-2 infection has a multifactorial pathogenesis and it is frequent in pediatric cases.

Case Presentation: We report a case with severe hypertransaminasemia associated with mild SARS-CoV-2 infection.

Conclusion: This highlights the potential need of hepatic function evaluation during acute illness and follow-up even in non-critically ill children with COVID-19.

Stress-Triggered Long-Distance Communication Leads to Phenotypic Plasticity: The Case of the Early Root Protoxylem Maturation Induced by Leaf Wounding in Arabidopsis.

Root architecture and xylem phenotypic plasticity influence crop productivity by affecting water and nutrient uptake, especially under those environmental stress, which limit water supply or imply excessive water losses. Xylem maturation depends on coordinated events of cell wall lignification and developmental programmed cell death (PCD), which could both be triggered by developmental- and/or stress-driven hydrogen peroxide (H₂O₂) production. Here, the effect of wounding of the cotyledonary leaf on root protoxylem maturation was explored in by analysis under Laser Scanning Confocal Microscope (LSCM).
