Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of

Strength and Detailing of Beams with High-Strength Headed and Hooked Stirrups

Thirty-nine large-scale reinforced concrete beams were tested under monotonic three-point bending to investigate the use of stirrups with mechanical anchors (heads) or hooks and Grade 80 (550) reinforcing steel. Grade 60 and 80 (420 and 550) No. 3, No. 4,

Sustainable and Seismically Resilient Confined Masonry: Global Progress in Research and Design Practice

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Modern confined masonry (CM) construction consists of masonry walls confined by reinforced concrete (RC) tie‐columns and tie‐beams. When built correctly, CM buildings have shown good performance in earthquake's shaking. Even though CM construction has been practised for almost a century in some Latin American countries, its use and standardisation are ...

Accessing Polyphenols Effect on Bond Strength and Dentin Enzymatic Degradation

Clinical and Experimental Dental Research, Volume 12, Issue 5, October 2026.
ABSTRACT Introduction Polyphenols have been investigated in dental materials and restorative techniques due to their interactions with metal cations, antioxidant activity, and collagen crosslinking ability, which make them a promise for reinforcing the dental substrate and improving material adhesion.

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 13, Page 3338-3362, 25 October 2026.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.

Women's experiences, responses, and coping strategies when testing positive for human papillomavirus in cervical cancer screening: A qualitative study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 10, Page 2104-2113, October 2026.
This study demonstrates that women's experiences following an hrHPV diagnosis within cervical screening extend beyond individual reactions to medical information, encompassing complex psychological, social, and cultural dimensions that influence how women interpret and manage the diagnosis.

Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

Journal of Anatomy, Volume 249, Issue 4, Page 847-864, October 2026.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

An Imaging‐Guided, Patient‐Specific Guiding Aid (RWNGuide) for Safe and Reproducible Inner Ear Drug Delivery

Advanced Materials Technologies, Volume 11, Issue 18, 18 September 2026.
A patient‐specific, imaging‐guided aid enables precise and reproducible drug delivery to the inner ear. By guiding therapeutic agents directly to the round window niche, this approach reduces variability in drug localization, improves delivery safety, and addresses a critical bottleneck in inner ear therapy, offering a scalable strategy for precision ...
