Summary: This study analyzed the content of nitrate (NO3-) and nitrite (NO2-) in commercial and self-made beetroot juices (BJs), finding that the levels of NO3- can vary with different seasons and storage conditions. The self-made BJ showed complete degradation of NO3- after 3 days at 20 degrees C, but this degradation was attenuated when stored at lower temperatures or with the addition of lemon juice. Additionally, self-made BJs had higher concentrations of NO2- and a higher pH compared to commercial BJs.

Summary: Nitric oxide (NO) (co)regulates physiological processes in the body and its availability is affected by aging. Aging leads to changes in nitrate and nitrite contents in tissues, with higher nitrate levels and lower nitrite levels in old rats compared to young rats. However, the nitrate reduction pathway is not affected by aging. Further investigation is needed to understand the changes in NO accessibility during aging.

Summary: Supplementation with L-arginine has been shown to have beneficial effects in hypertension by increasing nitric oxide formation and enhancing nitrate concentrations, but these effects may be prevented by antiseptic mouthwash. Alteration of the nitrate cycle in the body by mouthwash can impact endothelial dysfunction, antihypertensive effects, and antioxidant effects of L-arginine in hypertensive rats. The findings suggest a new mechanism where antibacterial mouth rinse can affect arterial blood pressure and the development of cardiovascular diseases.

Summary: Nitric oxide plays a crucial role in protecting the heart from ischemia reperfusion injury through the 'canonical' NO-sGC-cGMP pathway. A new nitrate-nitrite-NO pathway has been discovered to improve endothelial dysfunction, protect the myocardium and reduce infarct size.

Summary: Plants uptake and assimilate nitrogen from the soil, and nitrate and ammonium transporters play important roles in this process. Nitrogen is then incorporated into organic compounds through nitrogen metabolism pathways. Nitric oxide has been found to enhance plant survival under drought stress, and the interaction between nitrogen and salt stress has been studied. Excessive use of nitrate fertilizers can have negative impacts on health and the environment, highlighting the importance of alternative strategies. Genomics can identify new genes related to nitrogen fixation, which can be utilized to improve plant productivity.

Summary: This study investigates the hydrodynamics and cohesive-like characteristics of solid particles in a pseudo-2D droplet gas-solid fluidized bed using two-way coupled CFD-DEM numerical simulations. The results show that the presence of droplets leads to poorer fluidization characteristics, with increased surface tension resulting in inadequate mixing and higher liquid viscosity causing slower particle motion. The choice of contact angle is crucial for optimizing the fluidization quality, and injecting more droplets results in worse mixing, although the number of injected droplets has no significant effect on the flow pattern and particle motion.

Summary: Mass transfer has a significant impact on the NOx removal process in SCR, but characterizing the transport of gaseous species involved in the process at the nano-scale remains challenging. This study investigates the use of non-equilibrium molecular dynamics simulations to study the mass transfer of multi-pollutants over a titania-based catalyst. A dual control-volume model is proposed to simulate the transport of typical gaseous molecules, and the effects of temperature, pore width, hydroxyl sites, and competitive diffusion on diffusivity are studied. The results show that temperature and surface sites have a greater impact on NH3 than NO and SO2, with the influence of surface sites strongly dependent on size.

Summary: Ceria has attracted great interest as a catalyst for low-temperature selective catalytic reduction (SCR) of NOx due to its abundant surface oxygen species and redox property. The mechanism of how this redox property contributes to its SCR activity, however, is still debated. In this study, a model tungsten-promoted ceria catalyst was used to investigate the connections between NO oxidative activation and SCR turnovers. The results show that NO activation to nitrite intermediates is more favorable than oxidation to NO2, suggesting the prevalence of NO activation to nitrites in the SCR reaction.
