On the maximum value of the cosmic abundance of oxygen and the oxygen yield [PDF]
Mon.Not.Roy.Astron.Soc.376:353-360,2007, 2007 We search for the maximum oxygen abundance in spiral galaxies. Because this maximum value is expected to occur in the centers of the most luminous galaxies, we have constructed the luminosity - central metallicity diagram for spiral galaxies, based on a large compilation of existing data on oxygen abundances of HII regions in spiral galaxies.

BMC Neurology, 2018 Background Currently, it is challenging to detect the awareness of patients who suffer disorders of consciousness (DOC). Brain-computer interfaces (BCIs), which do not depend on the behavioral response of patients, may serve for detecting the awareness ...

Bonding, Conductance and Magnetization of Oxygenated Au Nanowires [PDF]
Phys. Rev. Lett. 100, 046801 (2008), 2013 Spin-density-functional calculations of tip-suspended gold chains, with molecular oxygen, or dissociated oxygen atoms, incorporated in them, reveal structural transitions for varying lengths. The nanowires exhibit enhanced strength for both oxygen incorporation modes, and upon stretching tip atoms join the wire.

CNS Neuroscience & Therapeutics, 2019 Hyperbaric oxygen therapy (HBOT) has been widely used as postinjury treatment; however, we investigate its ability to mitigate potential damage as a preconditioning option.

Hyperbaric oxygen in the management of wound tissue necrosis after external dacrocystorhinostomy [PDF]
, 2017 Hyperbaric oxygen is an adjunctive treatment for promoting wound healing and reducing infection. We present an unusual case of wound tissue necrosis occurring after external dacryocystorhinostomy (ExtDCR) that was subsequently treated with hyperbaric

Environmental risk factors and their footprints in vivo – a proposal for the classification of oxidative stress biomarkers [PDF]
, 2020 Environmental agents, including socioeconomic condition, and host factors can act as causal agents and risk factors in disease. We use biomarkers and sociomarkers to study causal factors, such as overproduction of reactive oxygen species (ROS) which ...

Hydrogen/nitrogen/oxygen defect complexes in silicon from computational searches [PDF]
Phys. Rev. B 80, 144112 (2009), 2009 Point defect complexes in crystalline silicon composed of hydrogen, nitrogen, and oxygen atoms are studied within density-functional theory (DFT). Ab initio Random Structure Searching (AIRSS) is used to find low-energy defect structures. We find new lowest-energy structures for several defects: the triple-oxygen defect, {3O}, triple oxygen with a ...

World Journal of Emergency Surgery, 2022 Background Necrotizing soft tissue infections (NSTI) require immediate radical debridement, broad-spectrum antibiotics and intensive care. Hyperbaric oxygen therapy (HBOT) may be performed adjunctively, but unequivocal evidence for its benefits is still ...
