Structure and function of nitrate and nitrite transporters, NrtA and NitA, from Aspergillus nidulans

open access: yes, 2009
Membrane proteins play an integral role in the control of ion transport across the cell membrane in biological systems. However, due to experimental constraints, structural and functional data available for these proteins is limited, especially ...

Lowering salivary pH with sugar‐containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice)

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Acutely lowering salivary pH (with sugar‐containing acidic gum vs. sugar‐free gum) augments salivary nitrate reduction to nitrite, plasma nitrite concentration, and blood pressure lowering with dietary nitrate. Modifying salivary pH reveals a mechanism by which the nitrate‐nitrite‐NO pathway may be upregulated/inhibited, with potential for other ...

Comparative Effects of White and Black Garlic on the Technological, Nutritional, and Sensory Properties of White and Whole Wheat Bread

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The response of bread systems to ingredient enrichment varies depending on flour composition and matrix structure. This study investigated the impact of white garlic (WG) and black garlic (BG) enrichment (1%–7%) on the technological properties, composition, antioxidants, and sensory characteristics of refined white ...

Electrochemical Design of Atomically Conformal Ga2O3 Buffer Layers via Cu2O‐Catalyzed Nitrate Reduction Reaction for Efficient Cu2O Photocathodes

open access: yesCarbon Energy, EarlyView.
Cu2O catalyzes nitrate reduction to locally generate OH− at the electrode surface, enabling the first uniform electrochemical deposition of Ga2O3. The Cu2O/Ga2O3‐based photocathodes achieve onset potentials above 1 VRHE, 3.8% solar‐to‐hydrogen efficiency, and stable operation for over 60 h in all‐inorganic tandem PEC devices.
