Selective hydrodeoxygenation of lignin-derived phenols to aromatics catalyzed by Nb2O5-supported iridium

open access: yes, 2022
Here we report the first heterogeneous iridium-based catalyst (Ir@Nb2O5) able to combine full conversion in hydrodeoxygenation (HDO) of lignin-derived phenols to hydrocarbons with appreciable selectivity for aromatics.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Soilless Cultivation System, Electrical Conductivity of Nutrient Solution, and Growing Season on Yield and Quality of Baby-Leaf Oak-Leaf Lettuce

open access: yesAgronomy, 2021
The floating system (FL) is a common soilless method for baby-leaf production, whereas the ebb and flow system (EF) has been proposed as an alternative. Both of them allow managing plant saline stress while preventing reduction in plant growth and yield ...

Dielectric Absorption at 3 cm. in Some Higher Alkyl Phenols [PDF]

open access: yes, 1963
Dielectric measurements have been carried out on para-octyl, -nonyl and -dodecyl phenols in solution in benzene at 3.22 cm. and at a radio frequency of 1 mc/sec. From the measurements at 3.22 cm.

Synthesis of salicylaldehydes from phenols via copper-mediated duff reaction

open access: yes, 2015
A copper-mediated Duff reaction for ortho-selective formylation of phenols has been developed. In the presence of copper species, significant improvements of yield and ortho-selectivity of the Duff formylation were achieved, which provides an easy access

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Effect of Salicylic Acid, 2,4-D and 2i-P on the Production of Secondary Metabolites in Garcinia brasiliensis Mart. Callus

open access: yesBrazilian Archives of Biology and Technology
The aim of this work was to evaluate the effect of Salicylic acid, 2,4-D and 2-iP on the production of total phenolic and flavonoids as well in the levels of fukugetin and 7-epiclusianone in callus of Garcinia brasiliensis zygotic embryos.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

PHENOL COEFFICIENTS

open access: yesAmerican Journal of Public Health, 1921
The author states that a phenol coefficient indicates relative germicidal efficiency under laboratory conditions only, and has no practical value. Users of disinfectants ordinarily “follow directions,” and employ the dilutions recommended by the manufacturers.
