Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Determinants of preterm pre‐eclampsia following low‐dose aspirin prophylaxis: evidence from stepped‐wedge cluster randomized trial in Asia

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives To identify potential risk factors – among maternal factors, pre‐eclampsia (PE)‐specific biomarkers and estimated risks derived from the first‐trimester Fetal Medicine Foundation (FMF) triple test – that are associated with the subsequent development of preterm PE, and to evaluate predictors of any‐onset PE using time‐to‐event ...

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

open access: yesVIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.
