Patch Testing in Individuals With Diabetes Using Medical Devices. Part 2—Contact Allergy to Medical Device Allergens and New Patch Test Recommendations

Contact Dermatitis, Volume 95, Issue 2, Page 169-181, August 2026.
This study aimed to describe the prevalence of contact allergy to allergens found in diabetes medical devices (MDs) among diabetes MD users and suggest an updated MD patch test series. Of the 204 diabetes MD users (114 with skin rash to diabetes MDs and 90 without), 16.2% were positive to allergens found in diabetes MDs, which underlines the urgent ...

NMR data for the hydroxyl groups detected by NOESY spectra in sesquiterpene lactones

Data in Brief, 2019
In this article we present the correlations observed in the NOESY spectra, which provide direct and unequivocal detection of hydroxyl groups occurring in the chemical structures of three sesquiterpene lactones - a germacranolide (8α-(E)-4 ...

Contact Sensitization in Patients With Frontal Fibrosing Alopecia: Patch Test Results With an Extended Baseline Series in Consecutive Patients

Contact Dermatitis, Volume 95, Issue 2, Page 192-199, August 2026.
Sensitization to propolis, shellac and gallate mix is FFA‐associated, but its relevance is largely unknown. Sensitization to salicylates is frequent and associated with symptoms of intolerance to sun exposure or sunscreens. No significant improvement by allergen avoidance is identified.

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2787-2826, August 2026.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Strigolactone‐mediated architecture regulation and stress resilience: Insights and innovations for crop breeding

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2548-2576, August 2026.
This review summarizes the discovery, biosynthesis, and transport of strigolactone, and the D14‐D3/MAX2‐D53/SMXLs signaling module. It highlights diverse roles of strigolactone in plant architecture, stress responses, and crop breeding, including species‐specific functions, hormonal crosstalk, and agricultural applications.
