SOIL CHEMISTRY TRENDS

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2010
In modern soil chemistry, four main directions are being actively developed: 1) chemistry of organic matter, 2) biochemical processes in soils, 3) chemical basis of soil protection, 4) soil study aschemical membrane and a pool of chemical elements ...

A Short Review of Current Computational Concepts for High-Pressure Phase Transition Studies in Molecular Crystals

open access: yesCrystals, 2020
High-pressure chemistry of organic compounds is a hot topic of modern chemistry. In this work, basic computational concepts for high-pressure phase transition studies in molecular crystals are described, showing their advantages and disadvantages.

Litter Quality of Populus Species as Affected by Free-Air CO2 Enrichment and N-Fertilization

open access: yes, 2009
The effect of elevated CO2 and nitrogen fertilization on the molecular chemistry of litter of three Populus species and associated soil organic matter (SOM) was investigated by pyrolysis-gas chromatography/mass spectrometry.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Taurine-Based Hybrid Drugs as Potential Anticancer Therapeutic Agents: In Vitro, In Vivo Evaluations

open access: yesPharmaceuticals
Background/Objectives: The development of antitumor agents possessing low toxicity against non-cancerous cells is still a challenge in medicinal chemistry. In this paper, we report the antitumor activity of “hybrid structures” derived from the amino acid

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 ...

Greener organic synthetic methods: Sonochemistry and heterogeneous catalysis promoted multicomponent reactions

open access: yesUltrasonics Sonochemistry, 2021
Ultrasound is an essential technique to improve organic synthesis from the point of view of green chemistry, as it can promote better yields and selectivities, in addition to shorter reaction times when compared to the conventional methods. Heterogeneous

Preparedness for tertiary chemistry: multiple applications of the chemistry competence test for diagnostic and prediction purposes [PDF]

open access: yes, 2011
This is a post-print of an article published by the Royal Society of Chemistry available at: http://dx.doi.org/10.1039/C1RP90024B.The development of the Chemistry Competence Test was prompted by the extensive curriculum changes in the South African ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

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.
