Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

P-phenylenediamine

open access: yes, 2014
P-phenylenediamine (PPD) is een sterk contactallergeen welke gebruikt wordt in oxidatieve haarverven en kan een ernstig contactallergisch eczeem veroorzaken.Hoewel PPD al jaren bekend staat als sterk contactallergeen, is het exacte mechanisme van sensibilisatie en elicitatie nog altijd niet compleet opgehelderd.

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...

Study on Diphenylamine Oxidation by Ozone Using Atmospheric Pressure Chemical Ionization Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Diphenylamine (DPAH) derivatives, widely used as antioxidants, interact with oxygen molecules (or ozone) to form radicals at the amine group. Although the antioxidation mechanism involves radical processes, separating these radicals using chromatography is challenging. Methods Rapid oxidation of DPAH was achieved through ozonation in

Unleashing the power of visible‐near infrared spectroscopy: predicting Golden Delicious apple enzyme activity

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7503-7511, September 2026.
Abstract BACKGROUND Enzymatic browning is a significant reaction in fruits that affects their color, appearance, and quality. The quality of apples, as a perishable product, is mainly influenced by the activity of two browning‐related enzymes, polyphenol oxidase (PPO) and peroxidase (POD), during storage.

Glove Reuse Limits in Hair Dyeing: Permeation of p‐Phenylenediamine and Aminophenols Through Natural Rubber Latex and Neoprene After Repeated Washing

open access: yesContact Dermatitis, Volume 95, Issue 3, Page 309-317, September 2026.
Disposable glove reuse reduced chemical protection during repeated hair‐dye exposure. Under ASTM F739 testing, natural‐rubber‐latex deteriorated rapidly after one reuse, whereas neoprene performed better initially but also declined over repeated cycles. Wash type had no significant effect. These findings support single‐use only and discourage the reuse

Contact Sensitisation Trends in Slovenian Children and Adolescents: A Retrospective Single‐Centre Study

open access: yesContact Dermatitis, Volume 95, Issue 3, Page 301-308, September 2026.
Nickel sensitisation in children decreased significantly over time, while dyes and isothiazolinones are emerging allergens. These findings underscore shifting exposure patterns and the need for continuous surveillance to guide effective patch testing and prevention strategies.

Patch Test Results With Additions to the European Baseline Series, 2021/22—Joint European Results of the ESSCAA and the EBSB Working Groups of the ESCD, and the GEIDACC

open access: yesContact Dermatitis, Volume 95, Issue 3, Page 276-285, September 2026.
ABSTRACT Background Allergens are periodically added to the European Baseline Series (EBS) to audit their value in consecutive patch testing. Objectives To present results of audit allergens tested in consecutive patients in 54 departments in 13 European countries during 2021 and 2022.

Epidemiological, Clinical and Allergic Profile of Patients With Dyshidrotic Eczema (Acute and Recurrent Vesicular Dermatitis): Evaluation of the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy (REIDAC)

open access: yesContact Dermatitis, Volume 95, Issue 3, Page 286-294, September 2026.
In this exploratory analysis, dyshidrotic eczema demonstrated a distinct sensitisation pattern compared with non‐dyshidrotic hand eczema. The lower proportion of clinically relevant reactions amongst positive patch tests suggests a multi‐factorial and not exclusively allergic background.
