ROS/pH‐Responsive Phenylboronic Acid–Chitosan Nanoparticles Improve Silymarin‐Mediated Hepatoprotection After Hepatectomy With Gut‐Liver Axis‐Associated Responses

Advanced Science, EarlyView.
Bioactive phenylboronic acid–chitosan nanoparticles enable responsive silymarin delivery for post‐hepatectomy liver protection. The nanoplatform integrates antioxidant and antibacterial functions, improves hepatic recovery, and is associated with coordinated shifts in gut microbiota, metabolites, cytokines, and hepatic proteomic pathways, suggesting a ...

Purification and Characterization of Nitrate Reductase (NAR) from Pseudomonas sp. SH7 Isolate

مجلة مركز بحوث التقنيات الاحيائية, 2010
Sixty five soil samples and fifteen water samples were collected from different places in which previously explosions were occurred in Iraq. Seven isolates showed ability to utilize 0.1mM trinitrotoluene (TNT) and/or 0.2mM glycerol trinitrate (GTN) as a

Photooxidative inhibition of nitrate reductase during chilling

, 1982
The effect of a temperature close to the freezing point (chilling) on the nitrate reductase system of leaf discs of Cucumis sativus L. cv. Kleine Groene Scherpe was determined in the absence and presence of light. The capacity of leaf discs in the light (

What is the role of the nitrate reductase (euknr) gene in fungi that live in nitrate-free environments? A targeted gene knock-out study in Ampelomyces mycoparasites

, 2021
Mycoparasitic fungi can be utilized as biocontrol agents (BCAs) of many plant pathogens. Deciphering the molecular mechanisms of mycoparasitism may improve biocontrol efficiency.

Lipid Metabolic Dysregulation Driven by OSMR Mutations Underlies Amyloidogenesis in Primary Localized Cutaneous Amyloidosis

Advanced Science, EarlyView.
OSMR mutations disrupt STAT5 signaling and AKR1B10‐mediated lipid metabolism, leading to lipid accumulation and protein aggregation in keratinocytes. This metabolic reprogramming drives amyloid deposition in primary localized cutaneous amyloidosis, revealing a mechanistic link between lipid dysregulation and amyloidogenesis.

A novel mechanism for dissimilatory nitrate reduction to ammonium in Acididesulfobacillus acetoxydans

mSystems
The biological route of nitrate reduction has important implications for the bioavailability of nitrogen within ecosystems. Nitrate reduction via nitrite, either to ammonium (ammonification) or to nitrous oxide or dinitrogen (denitrification), determines

The uptake and accumulation of phosphorous and nitrates and the activity of nitrate reductase in cucumber seedlings treated with PbCl2 or CdCl2

Acta Societatis Botanicorum Poloniae, 2014
Treatment of 4-day-old cucumber (Cucumis sativus L.) seedlings with PbCl2 or CdCl2 caused a significant increase in the accumulation of heavy metals by the plants, especially in the roots.

Host‐Specific Interactions Between Staphylococcus aureus and Pseudomonas aeruginosa Impair Epithelial Repair in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is frequently associated with polymicrobial biofilms involving Staphylococcus aureus and Pseudomonas aeruginosa. Interactions between these organisms are thought to influence disease severity, but the epithelial effects of exoproteins derived from patient‐matched cocultures remain poorly defined ...

REGULATION OF NITRATE REDUCTASE ACTIVITY IN RICE (ORYZA SATIVA L.) BY GROWTH REGULATORS [PDF]

Journal of Central European Agriculture, 2002
The effect of three growth regulators, namely kinetin, 6 benzyl adenine, 2 chloro ethyl trimethyl ammonium chloride at three concentrations (10-6 M, 5 x 10-5 M 10-4 M) was studied on the catalytic activity of nitrate reductase in green and etiolated ...
