The Root Clock as a Signal Integrator System: Ensuring Balance for Survival

open access: yesFrontiers in Plant Science, 2022
The root system is essential for the survival of terrestrial plants, plant development, and adaptation to changing environments. The development of the root system relies on post-embryonic organogenesis and more specifically on the formation and growth ...

Age and diabetes related changes of the retinal capillaries: an ultrastructural and immunohistochemical study [PDF]

open access: yes, 2015
Normal human aging and diabetes are associated with a gradual decrease of cerebral flow in the brain with changes in vascular architecture. Thickening of the capillary basement membrane and microvascular fibrosis are evident in the central nervous system

Retinal photodamage

open access: yesJournal of Photochemistry and Photobiology B: Biology, 2001
The retina represents a paradox, in that, while light and oxygen are essential for vision, these conditions also favour the formation of reactive oxygen species leading to photochemical damage to the retina. Such light damage seems to be multi-factorial and is dependent on the photoreactivity of a variety of chromophores (e.g., vitamin A metabolites ...
