Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

A New Approach to the Analysis of Dissolved Gases Using Passive Samplers, With Portable Mass Spectrometry and Gas Chromatography Techniques

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale Portable mass spectrometry systems such as miniRUEDI enable rapid and low‐cost field analysis of dissolved gases with high temporal resolution. However, they remain poorly suited for discrete small‐volume water samples. This study presents an approach based on passive sampling for groundwater and surface waters dissolved gases and ...

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

open access: yesMass Spectrometry Reviews, Volume 45, Issue 4, Page 829-850, July/August 2026.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

Integrating DynamiCROP model and risk assessment for pesticide residues in spinach: Implications for food safety

open access: yesPest Management Science, Volume 82, Issue 7, Page 7154-7163, July 2026.
This study adapted and validated the dynamiCROP model for spinach, a leafy vegetable not previously included in its standard framework. The findings confirm that model‐predicted pesticide concentrations, when integrated into hazard quotient (HQ) calculations, can effectively support dietary risk assessment.

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...
