Uncovering the Mechanisms of Long-Range Magnetic Order in [Mn(mal)(H2O)]n: Insights from Microscopic and Macroscopic Magnetic Analysis

open access: yesMagnetochemistry
In this study, we investigate the magnetic properties of the molecular compound [Mn(mal)(H2O)]ₙ (mal = dianion of malonic acid) by integrating microscopic and macroscopic characterization, combining unpolarized neutron diffraction and magnetometry ...

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

open access: yesJournal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Multi‐Omics Signatures of Periodontitis and Periodontal Therapy on the Oral and Gut Microbiome

open access: yesJournal of Periodontal Research, EarlyView.
This multi‐omics study integrates shotgun metagenomics and NMR metabolomics to reveal coordinated microbial and metabolic signatures of periodontitis across the oral–gut axis. Non‐surgical periodontal therapy partially restored ecological and functional balance, supporting oral health as a modifiable driver of systemic microbial homeostasis.

Comparative proteomics analysis of root and nodule mitochondria of soybean

open access: yesPlant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Quantifying the Electrophilicity of 9(10H)‐Phenanthrenone‐ and 1‐Acenaphthenone‐Derived α, β‐Unsaturated Ketones

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 2, February 2026.
The electrophilicities (Mayr E) of the α, β‐unsaturated ketones A and B were determined by kinetic studies of their reactions with carbanions (reference nucleophiles) in DMSO at 20°C. The different reactivities of A and B were rationalized by DFT calculations.

Spirosilanes Activate Gold(I)‐Catalysts in Cycloisomerization and Intermolecular Reactions

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Spirosilanes activate LAuCl complexes to promote catalysis. This silver‐free activation through weak interactions is nondestructive so that low loadings of LAuCl are possible as well as their recycling. It can also be beneficial for asymmetric catalysis.

Ligações hidrogênio fortes em ácidos dicarboxílicos e diaminas aromáticas

open access: yesQuímica Nova, 2000
A very short-strong hydrogen bond (20kcal/mol) is found in the monoanion of certain dicarboxylic acids derived from maleic and dialkylmalonic acids. Certain aromatic diamines that are known as proton sponge have exceptionally high basicity (pKa) and are ...
