Response and Recovery of the Comanche Carbonate Platform Surrounding Multiple Cretaceous Oceanic Anoxic Events, Northern Gulf of Mexico [PDF]

open access: yes, 2015
The ubiquity of carbonate platforms throughout the Cretaceous Period is recognized as a product of high eustatic sea-level and a distinct climatic optimum induced by rapid sea-floor spreading and elevated levels of atmospheric carbon-dioxide.

Climate warming, euxinia and carbon isotope perturbations during the Carnian (Triassic) Crisis in South China [PDF]

open access: yes, 2016
The Carnian Humid Episode (CHE), also known as the Carnian Pluvial Event, and associated biotic changes are major enigmas of the Mesozoic record in western Tethys.

ROS production and scavenging under anoxia and re-oxygenation in Arabidopsis cells: a balance between redox signaling and impairment.

open access: yesFrontiers in Plant Science, 2016
Plants can frequently experience low oxygen concentrations due to environmental factors such as flooding or waterlogging. It has been reported that both anoxia and the transition from anoxia to re-oxygenation determine a strong imbalance in the cellular ...

Nitrous Oxide Emissions from Paddies: Understanding the Role of Rice Plants

open access: yesPlants, 2020
Paddies are a potential source of anthropogenic nitrous oxide (N2O) emission. In paddies, both the soil and the rice plants emit N2O into the atmosphere.

Neuroprotective effects of some creatine derivative compounds

open access: yesJournal of Biological Research, 2010
Some derivatives more lipophylic than creatine, thus theoretically being capable to better cross the blood-brain barrier, were studied for their neuroprotective effect in mouse hippocampal slices.

Modeling eutrophication and oligotrophication of shallow-water marine systems: the importance of sediments under stratified and well-mixed conditions [PDF]

open access: yes, 2009
A one-dimensional model that couples water-column physics with pelagic and benthic biogeochemistry in a 50-m-deep water column is used to demonstrate the importance of the sediment in the functioning of shallow systems, the eutrophication status of the ...

Close mixed-planting with paddy rice reduced the flooding stress for upland soybean

open access: yesPlant Production Science, 2022
Close mixed-planting is a new concept of mixed cropping that allows greater complementary effects under various stress conditions; in this system, oxygen and/or water transfer occurs through the tightly entangled root system of the two species.

Diurnal effects of anoxia on the metabolome of the seagrass Zostera marina [PDF]

open access: yes, 2015
We investigated the response, adaptation and tolerance mechanisms of the temperate seagrass Zostera marina to water column anoxia. We exposed Z. marina to a diurnal light/dark cycle under anoxia and assessed the metabolic response by measuring the ...

Geochemical and ecological aspects of lower Frasnian pyrite-ammonoid level at Kostomłoty (Holy Cross Mountains, Poland) [PDF]

open access: yes, 2004
The lower Frasnian (transitans Zone with Ancyrodella priamosica = MN 4 Zone) rhythmic basin succession of marly limestones and shales (upper Szydlówek Beds) at Kostomloty, western Holy CrossMts., Central Poland, contains a record of the transgressive ...

Spontaneous running wheel exercise during pregnancy prevents later neonatal-anoxia-induced somatic and neurodevelopmental alterations

open access: yesIBRO Neuroscience Reports
Introduction: About 15–20 % of babies that suffer perinatal asphyxia die and around 25 % of the survivors exhibit permanent neural outcomes. Minimization of this global health problem has been warranted.
