What Did We Accomplish in Fighting Radical Species in Human Health?

open access: yesAntioxidants, 2021
Maintaining the physiological level of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the body is highly important in the fight against radical species in the context of human health [...]

Biological aspects of reactive nitrogen species

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 1999
Nitric oxide (NO) plays an important role as a cell-signalling molecule, anti-infective agent and, as most recently recognised, an antioxidant. The metabolic fate of NO gives rise to a further series of compounds, collectively known as the reactive nitrogen species (RNS), which possess their own unique characteristics.

Effects of Antimony on Reactive Oxygen and Nitrogen Species (ROS and RNS) and Antioxidant Mechanisms in Tomato Plants

open access: yesFrontiers in Plant Science, 2020
This research studies the effects that Sb toxicity (0.0, 0.5, and 1.0 mM) has on the growth, reactive oxygen and nitrogen species, and antioxidant systems in tomato plants.

Dangers of hyperoxia

open access: yesCritical Care, 2021
Oxygen (O2) toxicity remains a concern, particularly to the lung. This is mainly related to excessive production of reactive oxygen species (ROS). Supplemental O 2 , i.e. inspiratory O2 concentrations (FIO2) > 0.21 may cause hyperoxaemia (i.e.

Santa Giusta Lagoon (Sardinia): phytoplankton and nutrients before and after waste water diversion [PDF]

open access: yes, 2001
The purpose of this paper was to assess the effect of the diversion of waste water on the trophic status of the Stagno di Santa Giusta, a hypertrophic lagoon on the centre-western coast of Sardinia.

Interplay between oxidant species and energy metabolism

open access: yesRedox Biology, 2016
It has long been recognized that energy metabolism is linked to the production of reactive oxygen species (ROS) and critical enzymes allied to metabolic pathways can be affected by redox reactions. This interplay between energy metabolism and ROS becomes

Tropospheric reactive odd nitrogen over the South Pacific in austral springtime [PDF]

open access: yes, 2000
The distribution of reactive nitrogen species over the South Pacific during austral springtime appears to be dominated by biomass burning emissions and possibly lightning and stratospheric inputs.

Reactive nitrogen budget during the NASA SONEX Mission [PDF]

open access: yes, 1999
The SASS Ozone and Nitrogen Oxides Experiment (SONEX) over the North Atlantic during October/November 1997 offered an excellent opportunity to examine the budget of reactive nitrogen in the upper troposphere (8–12 km altitude).
