Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy

Advanced Science, EarlyView.
This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...

Heavy Metal Contamination: Impacts From Plants to the Food Chain and Eco‐Friendly Amelioration Strategies

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

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 ...

Omeprazole Treatment Enhances Nitrogen Use Efficiency Through Increased Nitrogen Uptake and Assimilation in Corn

Frontiers in Plant Science, 2019
Omeprazole is a selective proton pump inhibitor in humans that inhibits the H+/K+-ATPase of gastric parietal cells. Omeprazole has been recently shown to act as a plant growth regulator and enhancer of salt stress tolerance.

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

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.

Synthesis and Activity‐Based Protein Profiling Identifies Aldo‐Keto Reductase 1C3 as Target Protein of Myxoglucamides

Angewandte Chemie International Edition, EarlyView.
Myxoglucamide A—a novel glycolipopeptide isolated from myxobacteria—was synthesized, and activity‐based protein profiling identified aldo‐keto reductase 1C3 (AKR1C3) as its main target in human cells. Structure‐activity relationship studies, together with biophysical characterization and X‐ray crystallography, elucidated the structural basis of AKR1C3 ...
