Effect of manure, clay, charcoal, zeolite, and calcium oxide on some properties of soil contaminated with cobalt

open access: yesSoil Science Annual, 2017
The study has been undertaken in order to determine the influence of different substances (manure, clay, charcoal, zeolite and calcium oxide) on soil pH, hydrolytic acidity, total exchangeable bases, cation exchange capacity, the base saturation of soil ...

Spatial Distribution and Evolution of pH as a Function of Cation Exchange Capacity, Sum of Exchangeable Bases, and Organic Matter and Aluminum in the Soils of Foumban

open access: yesApplied and Environmental Soil Science, 2023
Foumban, located in the Noun valley in western Cameroon, is a prime location for food production. However, this locality is experiencing a significant decline in productivity due to the acidity of its soil.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Selected properties of cobalt-contaminated soil following the application of neutralising substances

open access: yesEnvironmental Protection and Natural Resources, 2016
The aim of the study was to determine the influence of increasing cobalt soil contamination (0 mg·kg−1, 20 mg·kg−1, 40 mg·kg−1, 80 mg·kg−1, 160 mg·kg−1, 320 mg·kg−1) after the application of neutralising substances on selected soil properties.

Lewis Acid-Catalyzed Sulfur Fluoride Exchange

open access: yesOrganic Letters
A new method uses metal Lewis acids as catalysts to convert sulfonyl fluorides, fluorosulfates, and sulfamoyl fluorides with silyl amines into S-N bond-containing compounds via sulfur fluoride exchange. The reaction successfully employs Ca(NTf2)2 as a catalyst to form sulfonamides, sulfamates, and sulfamides using in situ-generated or commercially ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
