Blood Pressure–Lowering Effect of Orally Ingested Nitrite Is Abolished by a Proton Pump Inhibitor

open access: yesHYPERTENSION, 2017
Inorganic nitrate and nitrite from dietary and endogenous sources are metabolized to NO and other bioactive nitrogen oxides that affect blood pressure.

Evaluation of the Haematological Responses to High Nitrate Exposure in Rabbits [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2012
Introduction: Nitrate is a common pollutant in the drinking water of Rajasthan as well as in the rest of India. The maximum permissible limit for the nitrate ion in drinking water has been set at 50 mg/l by the WHO and at 45 mg/ l by the Bureau of ...

Boosting Nitrate Electroreduction to Ammonia on Alloying of Cu With Au by Accelerated Proton Relay

open access: yesAggregate, EarlyView.
Carbon‐supported coral‐like Au3Cu alloy relay catalysts were synthesized by electrodeposition and used for the reduction of NO3− to NH3, where the NH3 production rate was 1719.3 µg h−1 cm−2 at −0.5 V. Theoretical density functional theory results show that Cu in the catalyst favors the reduction of NO3– to *NO, while Au favors the reduction of *NO to ...

A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces

open access: yesAsian Journal of Organic Chemistry, Accepted Article.
This study reports the development of a synthetic route for the chemical environment sensor C10SP, designed for incorporation into phytantriol‐based cubosomes. The molecule combines an apolar aliphatic tail for lipid bilayer anchoring with a polarity‐sensitive chromophore.

Photoswitchable, Water‐Soluble Bisazobenzene Cross‐Linkers with Enhanced Properties for Biological Applications

open access: yesChemPhotoChem, Volume 6, Issue 12, December 2022., 2022
Photoswitchable cross‐linkers have the ability to connect two residues on a biomolecule, thereby causing large changes in the structure and function of the target upon irradiation. The design, synthesis and purification of cross‐linkers with large end‐to‐end distances remains challenging, especially for applications in chemical biology.

The Influence of Stirring Speed, Temperature and Initial Nitrogen Concentration on Specific Anammox Activity

open access: yesBrazilian Archives of Biology and Technology, 2018
This study evaluates the influence of initial nitrogen concentration, temperature and stirring speed on specific anammox activity (SAA). The biomass was tested in single batch reactors with different initial nitrogen concentrations (Assay 1) ranging from

Electronic structure of nanocones of boron nitrite [PDF]

open access: yesApplied Physics Letters, vol 82 (14), p. 2323-2325, 7 April 2003, 2004
We apply first-principles calculations to study the electronic structure of boron nitride nanocones with disclinations of different angles $\theta=n\pi/3$. Nanocones with odd values of $n$ present antiphase boundaries that cause a reduction of the work function of the nanocones, relative to the bulk BN value, by as much as 2 eV.
