The effect of simulated nitrogen deposition on soil chemical properties in maple plantation stand [PDF]
علوم محیطی, 2017 Introduction: The amount of nitrogen compounds released into the atmosphere has increased, and is higher in industrial areas due to the increasing usage of fossil fuels and chemical fertilizers (Gruber and Galloway, 2008).

Soil mineral nitrogen and the rating of CaCl2 extractable nutrients
Plant, Soil and Environment, 2017 It was assumed that the determination of the mineral nitrogen (Nmin) content in the 0.01 mol/L CaCl2 could rely on measurements of single form NO3--N, NH4+-N or both, and even including other extractable nutrients.

pH-Based Control Strategies for the Nitrification of High-Ammonium Wastewaters
Fermentation, 2021 Aquatic nitrogen pollution is one of the most urgent environmental issues requiring prevention and mitigation. Large quantities of high-ammonium wastewaters are generated by several industrial sectors, such as fertilizer and anaerobic-digestion plants ...

Molecular Oncology, EarlyView.Using multi‐omic characterization, we aimed to identify key regulators specific to squamous cell lung carcinoma (SqCC). SqCC‐specific differentially expressed genes were integrated with metabolics data. High expression of the creatine transporter SLC6A8, along with elevated creatine levels, appeared to be a distinct metabolic feature of SqCC.

Rejected Sago Starch as a Coating Material to Mitigate Urea-Nitrogen Emission
Agronomy, 2022 Urea–nitrogen is commonly lost through ammonia (NH3) volatilization, denitrification, and nitrate (NO3−) leaching. Rejected sago starch (RSS), which is a by-product of sago flour extraction, could be used to minimize NH3 volatilization from urea.

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression
Molecular Oncology, EarlyView.Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

Ammonium imidazolium dichromate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the crystal structure of the title compound, (C3H5N2)(NH4)[Cr2O7], the anions and cations are linked through N—H...O hydrogen bonds, resulting in a three-dimensional structure which contains three kinds of layers parallel to (001). One layer contains imidazole cations, the other two layers the ammonium cations and dichromate anions.
