Age-related differences of the time-varying features in the brain functional connectivity and cognitive aging.

Brain functional modular organization changes with age. Considering the brain as a dynamic system, recent studies have suggested that time-varying connectivity provides more information on brain functions. However, the spontaneous reconfiguration of modular brain structures over time during aging remains poorly understood.

MicroRNAs and targets in senescent litchi fruit during ambient storage and post-cold storage shelf life.

Background: Litchi has a high commercial value due to its bright color and rich nutrients. However, it deteriorates with the pericarp turning brown within 1-2 days after harvest. The factors that mediate litchi fruit senescence are complicated.
