An Aptitude for Altitude: Are Epigenomic Processes Involved?

open access: yesFrontiers in Physiology, 2019
In recent years, high-throughput genomic technologies and computational advancements have invigorated efforts to identify the molecular mechanisms regulating human adaptation to high altitude. Although exceptional progress regarding the identification of

Polycyclic Aromatic Hydrocarbons Have Adverse Effects on Benthic Communities in the Baltic Sea: Implications for Environmental Status Assessment

open access: yesFrontiers in Environmental Science, 2021
Changes in benthic macrofaunal communities are indicative of environmental stressors, including eutrophication and hypoxia. However, some species are sensitive not only to hypoxia but also to various environmental contaminants.

Effects of Normobaric Hypoxia on Oculomotor Dynamics of Aviator Students during a Simulated Flight Task [PDF]

open access: yes, 2020
Hypoxia occurs when the body\u27s tissues are unable to obtain adequate oxygen supply and is the primary environmental factor present when pilots are exposed to increasing altitude levels.

Glial response to hypoxia in mutants of NPAS1/3 homolog Trachealess through Wg signaling to modulate synaptic bouton organization.

open access: yesPLoS Genetics, 2019
Synaptic structure and activity are sensitive to environmental alterations. Modulation of synaptic morphology and function is often induced by signals from glia. However, the process by which glia mediate synaptic responses to environmental perturbations

Interactions between oxygen homeostasis, food availability, and hydrogen sulfide signaling

open access: yesFrontiers in Genetics, 2012
The ability to sense and respond to stressful conditions is essential to maintain organismal homeostasis. It has long been recognized that stress response factors that improve survival in changing conditions can also influence longevity.

Multi-omics analysis revealed the brain dysfunction induced by energy metabolism in Pelteobagrus vachelli under hypoxia stress

open access: yesEcotoxicology and Environmental Safety, 2023
Hypoxia in water environment has become increasingly frequent and serious due to global warming and environmental pollution. Revealing the molecular mechanism of fish hypoxia adaptation will help to develop markers of environmental pollution caused by ...

Differential Expression of miRNAs in the Respiratory Tree of the Sea Cucumber Apostichopus japonicus Under Hypoxia Stress

open access: yesG3: Genes, Genomes, Genetics, 2017
The sea cucumber, an important economic species, has encountered high mortality since 2013 in northern China because of seasonal environmental stress such as hypoxia, high temperature, and low salinity. MicroRNAs (miRNAs) are important in regulating gene

Hypoxia and other environmental factors at high altitude

open access: yesInternational Journal of Environment and Health, 2008
Besides hypoxia, high altitude settings are characterised by other peculiar environmental factors, such as cold and ultraviolet radiation. In addition, there are prevalent environmental changes driven mainly by human activity, including climate change in the highland Andes, and outdoor and indoor pollution.

Tissue-Specific Orchestration of Gilthead Sea Bream Resilience to Hypoxia and High Stocking Density [PDF]

open access: yes, 2019
Two different O-2 levels (normoxia: 75-85% O-2 saturation; moderate hypoxia: 42-43% O-2 saturation) and stocking densities (LD: 9.5, and HD: 19 kg/m(3)) were assessed on gilthead sea bream (Sparus aurata) in a 3-week feeding trial.

Predicting the effects of coastal hypoxia on vital rates of the planktonic copepod Acartia tonsa Dana. [PDF]

open access: yesPLoS ONE, 2013
We describe a model predicting the effects of low environmental oxygen on vital rates (egg production, somatic growth, and mortality) of the coastal planktonic copepod Acartia tonsa.
