HNRNPU K181 Lactylation Drives Cervical Cancer Growth by Upregulating PHGDH and Reprogramming Serine Metabolism

open access: yesAdvanced Science, EarlyView.
Lactate in cervical cancer induces HNRNPU K181 lactylation, opposed by NAA50‐mediated acetylation and suppressed by Pazopanib. This lactylation enhances HNRNPU binding to PHGDH pre‐mRNA exon 1, maintaining exon 1‐containing transcripts and mRNA stability, thereby activating serine metabolism.

Quantitative evaluation of ruminal methane and carbon dioxide formation from formate through C-13 stable isotope analysis in a batch culture system

open access: yesAnimal, 2019
Methane produced from formate is one of the important methanogensis pathways in the rumen. However, quantitative information of CH4 production from formate has been rarely reported.

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

open access: yesAdvanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Efficient Electrocatalytic Conversion of CO2 to Pure Formic Acid Solutions via Strain‐Engineered Bismuth Nanosheets

open access: yesAdvanced Science, EarlyView.
Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...

Estudio del mecanismo de reacción de la oxidación de isopropanol sobre óxidos mixtos de Mn-Ti mediante espectroscopía FT-IR y cromatografía de gases

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2000
Several samples of TiO2 (anatase)-supported Mn oxide have been prepared by a wet impregnation method, named as XMn- TiO2 (with X = 0.5, 1.0, 1.5 and 2.0, the theoretical monolayer fractions). All samples were characterised by conventional techniques.

Electrochemical Reduction of CO2 to Formate on Easily Prepared Carbon-Supported Bi Nanoparticles

open access: yesMolecules, 2019
Herein, the electrochemical reduction of CO2 to formate on carbon-supported bismuth nanoparticles is reported. Carbon-supported Bi nanoparticles (about 10 nm in size) were synthesized using a simple, fast and scalable approach performed under room ...

First-Principles Study of Structure and Magnetism in Copper(II)-Containing Hybrid Perovskites

open access: yesCrystals, 2020
We report a first-principles study of hybrid organic–inorganic perovskites with formula [A]Cu(H2POO)3 (A = triazolium (Trz) and guanidinium (Gua), and H2POO− = hypophosphite), and [HIm]Cu(HCO2)3 (HIm = imidazolium cation, HCO2− = formate). The triazolium

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation

open access: yesAdvanced Science, EarlyView.
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).

Screening and fermentation process of single cell protein-producing strains by formic acid

open access: yesSiliao yanjiu, 2021
The study aimed to screen and isolate efficient strains that can use formic acid to produce single-cell protein, and study its physiological characteristics and fermentation process. In the study, the medium with 5 g/L sodium formate as carbon source was

Biofilm Formation Studies in Microtiter Plate Format

open access: yes, 2012
Although Candida biofilms have been clearly identified as playing an increasingly important role in human disease, their biology and the reason for their poor susceptibility to antifungal agents remain largely unknown. Over recent years, various models have been developed in order to better characterize Candida biofilms.
