Microbial degradation of phenol and phenolic derivatives

Engineering in Life Sciences, 2013
Phenol and its derivatives are one of the largest groups of environmental pollutants due to their presence in many industrial effluents and broad application as antibacterial and antifungal agents. A number of microbial species possess enzyme systems that are applicable for the decomposition of various aliphatic and aromatic toxic compounds.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Reactions of Phenolic Mannich Bases with Phenols

The Journal of the Society of Chemical Industry, Japan, 1958
1)フェノールマンニッヒ塩基とフェノール類との反応は,フェノール性OH基の酸性度が大きいほど分解反応大でまたフェノール類添加により促進されるが,アニソールのようにOH基を有しないと促進しない。2)ニトロフェノール,アニリン等の添加により分解反応が促進される。また,これがオルトマンニッヒ塩基と,パラ,マンニッヒ塩基とにより大きく差を生じ,オルトマンニッヒ塩基において効果大で,パラマンニッヒ塩基であまり効果を認めなかった。3)オルトマンニッヒ塩基で,2,4-二置換フェノールを用いたものと相手フェノールを2,4-ジメチルフェノールとの,反応で, 発生ジメチルアミンの追跡により, 初期反応を2 次反応速度として取扱うことができる。マンニッヒ塩基の置換基RがCH3では活性化熱13.6kcal/mol ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron
