Aminoethyl nitrate – the novel super nitrate? [PDF]

open access: yesBritish Journal of Pharmacology, 2009
Long‐term use of most organic nitrates is limited by development of tolerance, induction of oxidative stress and endothelial dysfunction. In this issue of the BJP, Schuhmacher et al. characterized a novel class of organic nitrates with amino moieties (aminoalkyl nitrates).

Efficient syntheses of climate relevant isoprene nitrates and (1R,5S)-(−)-myrtenol nitrate [PDF]

open access: yes, 2016
Here we report the chemoselective synthesis of several important, climate relevant isoprene nitrates using silver nitrate to mediate a ’halide for nitrate’ substitution. Employing readily available starting materials, reagents and Horner–Wadsworth–Emmons

Increased Nitrogen Availability in the Soil Under Mature Picea abies Trees Exposed to Elevated CO2 Concentrations

open access: yesFrontiers in Forests and Global Change, 2019
The response of trees to increasing atmospheric CO2 concentrations is often mediated by the availability of nutrients. However, little is known about the influence of CO2 enrichment on nutrient availability in forests with mature trees.

Drinking Water Nitrate and Human Health: An Updated Review

open access: yesInternational Journal of Environmental Research and Public Health, 2018
Nitrate levels in our water resources have increased in many areas of the world largely due to applications of inorganic fertilizer and animal manure in agricultural areas.

Nitrate in 2020: Thirty Years from Transport to Signaling Networks

open access: yesThe Plant Cell, 2020
Nitrogen (N) is an essential macronutrient for plants and a major limiting factor for plant growth and crop production. Nitrate is the main source of N available to plants in agricultural soils and in many natural environments.

Quantification of nitrate removal by a flooded alluvial zone in the Ill floodplain (Eastern France) [PDF]

open access: yes, 1999
The nitrate reducing capacity of a flooded system in the Ill floodplain (Eastern France) was investigated for a period of 2 years. The methodology used consisted of a spatio-temporal monitoring of stream flow and nitrate concentrations in the groundwater

Spraying humic acid regulator on cultivated Codonopsis pilosula (Franch.) Nannf. to improve yield of active constituents

open access: yesFrontiers in Plant Science
Plant growth regulators have been used in the cultivation of medicinal plants to increase yield, but the existing regulators decreased the content of active constituents which benefit human health.

Denitrification and Biodiversity of Denitrifiers in a High-Mountain Mediterranean Lake

open access: yesFrontiers in Microbiology, 2017
Wet deposition of reactive nitrogen (Nr) species is considered a main factor contributing to N inputs, of which nitrate (NO3−) is usually the major component in high-mountain lakes.

Nitrate and phosphate availability and distribution have different effects on root system architecture of Arabidopsis [PDF]

open access: yes, 2002
Plant root systems can respond to nutrient availability and distribution by changing the three-dimensional deployment of their roots: their root system architecture (RSA). We have compared RSA in homogeneous and heterogeneous nitrate and phosphate supply

Oral Nitrate Supplementation Differentially Modulates Cerebral Artery Blood Velocity and Prefrontal Tissue Oxygenation During 15 km Time-Trial Cycling in Normoxia but Not in Hypoxia

open access: yesFrontiers in Physiology, 2018
Background: Nitrate is a precursor of nitric oxide (NO), an important regulator of cerebral perfusion in normoxic and hypoxic conditions. Nitrate supplementation could be used to improve cerebral perfusion and oxygenation during exercise in hypoxia.
