Nitrate Reduction to Nitrite, a Possible Source of Nitrite for Growth of Nitrite-Oxidizing Bacteria [PDF]

open access: yesApplied and Environmental Microbiology, 1977
Growth yields and other parameters characterizing the kinetics of growth of nitrite-oxidizing bacteria are presented. These parameters were measured during laboratory enrichments of soil samples with added nitrite. They were then used to reanalyze data for nitrite oxidizer growth in a previously reported field study (M. G. Volz, L.

Nanoelectrodes for intracellular measurements of reactive oxygen and nitrogen species in single living cells [PDF]

open access: yesCurrent Opinion in Electrochemistry, Elsevier, 2020, 22, pp.44-50, 2020
Reactive oxygen and nitrogen species (ROS and RNS) play important roles in various physiological processes (e.g., phagocytosis) and pathological conditions (e.g., cancer). The primary ROS/RNS, viz., hydrogen peroxide, peroxynitrite ion, nitric oxide, and nitrite ion, can be oxidized at different electrode potentials and therefore detected and ...

Comparative activity of dimethyl fumarate derivative IDMF in three models relevant to multiple sclerosis and psoriasis

open access: yesFEBS Open Bio, EarlyView.
IDMF is a derivative of dimethyl fumarate (DMF) with a unique therapeutic potential at the intersection of psoriasis and multiple sclerosis. Here, we demonstrate that it compares favorably with DMF and its other derivatives, such as Diroximel, in the zebrafish, microglia, and lymphocyte models.

Acacetin reduces endoplasmic reticulum stress through the P‐eNOS/PERK signaling pathway to attenuate MGO‐induced vascular endothelial cell dysfunction

open access: yesFEBS Open Bio, EarlyView.
We investigated a potential protective effect of acacetin, a naturally occurring flavonoid, against methylglyoxal (MGO)‐induced endothelial dysfunction in human umbilical vein endothelial cells and its mechanism of action. Acacetin can could inhibit MGO‐induced intracellular calcium ion influx, enhance the expression levels of phosphorylated ...

Effect of the microbial activity on nitrification in soils cultivated with Brachiaria humidicola (Rendle) Schweicerdt in Cerete, Cordoba

open access: yesTemas Agrarios, 2015
Nitrogen fertilizers used in agriculture have increased the emissions of nitrogen oxides to the atmosphere. This study evaluated the production of NO2 - (nitrite) and N03 - (nitrate) by soilborne bacteria during the dry and the rainy seasons in The ...
