Glutathione Depletion Disrupts Redox Homeostasis in an Anoxia-Tolerant Invertebrate

open access: yesAntioxidants, 2023
The upregulation of endogenous antioxidants is a widespread phenomenon in animals that tolerate hypoxia/anoxia for extended periods. The identity of the mobilized antioxidant is often context-dependent and differs among species, tissues, and stresses ...

Photochemical colour change for traditional watercolour pigments in low oxygen levels [PDF]

open access: yes, 2014
An investigation for light exposure on pigments in low-oxygen environments (in the range 0–5% oxygen) was conducted using a purpose-built automated microfadometer for a large sample set including multiple samples of traditional watercolour pigments from ...

Newborn hypoxia/anoxia inhibits cardiomyocyte proliferation and decreases cardiomyocyte endowment in the developing heart: role of endothelin-1. [PDF]

open access: yesPLoS ONE, 2015
In the developing heart, cardiomyocytes undergo terminal differentiation during a critical window around birth. Hypoxia is a major stress to preterm infants, yet its effect on the development and maturation of the heart remains unknown.

Diverse Response Pattern to Anoxia in Three Freshwater Turtle Species

open access: yesBiology, 2022
With increasing water eutrophication and global warming, anoxia and hypoxia are becoming more and more common in water environments. Most vertebrates have a limited tolerance to anoxia of only a few minutes, but some species, such as turtles, can survive

Foraminiferal species responses to in situ, experimentally induced anoxia in the Adriatic Sea [PDF]

open access: yesBiogeosciences, 2014
Anoxia was successfully induced in four benthic chambers installed at 24 m depth in the northern Adriatic Sea for periods varying from 9 days to 10 months. During the 10-month period, species richness significantly decreased.

MitosRNAs and extreme anoxia tolerance in embryos of the annual killifish Austrofundulus limnaeus

open access: yesScientific Reports, 2019
Embryos of the annual killifish Austrofundulus limnaeus are the most anoxia-tolerant vertebrate. Annual killifish inhabit ephemeral ponds, producing drought and anoxia-tolerant embryos, which allows the species to persist generation after generation ...

Mitochondrial DNA sequence and lack of response to anoxia in the annual killifish Austrofundulus limnaeus

open access: yesFrontiers in Physiology, 2016
The annual killifish Austrofundulus limnaeus inhabits ephemeral ponds in regions of Venezuela, South America. Permanent populations of A. limnaeus are maintained by production of stress-tolerant embryos that are able to persist in the desiccated ...

Pediatric liver transplantation from neonatal donors [PDF]

open access: yes, 1992
Sixteen recipients of neonatal liver grafts were compared with 114 contemporaneous pediatric recipients of grafts from older donors. Graft and patient survival were worse in the neonatal group although the differences were not statistically significant ...
