Assessing Angiogenic Properties In Vitro or In Ovo of Pre‐Crosslinked Alginate‐Dialdehyde‐Gelatin Hydrogels Incorporating Boron‐Doped Mesoporous Bioactive Glass Particles

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study examines the influence of boron‐doped mesoporous bioactive glass nanoparticles (MBGN) blended in cast and 3D‐printed pre‐crosslinked alginate‐dialdehyde‐gelatin (ADA‐GEL). Addition of 0.5% and 1% MBGN did not negatively affect the viability of human umbilical vein endothelial cells (HUVECs), or the sprouting of HUVEC spheroids.

Microscopic state of BHs and an exact one body method for binary dynamics in general relativity

open access: yesEuropean Physical Journal C: Particles and Fields
In gravitational collapses, the horizon and singularity’s realisation in the finite future of the proper time used co-moving observer happens in the future of infinitely far away future of the normal time used outside probe. To the latter the horizon and

A solution for non-stationary, slowly-rotating, cylindrically symmetric, perfect fluid universe

open access: yesRuhuna Journal of Science, 2007
An analytic solution for the relativistic field equations is obtained for a non-stationary, slowly rotating, cylindrically symmetric distribution of perfect fluid universe. The new metric, is regular with the exception at the point r = 0.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

open access: yesThe Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

open access: yesThe Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

A gamified formative question bank to enhance student learning and engagement in a foundational medical science course

open access: yesAnatomical Sciences Education, EarlyView.
Abstract While gamified learning platforms show promise for engaging digital learners and promoting active learning, evidence of their effectiveness in predicting academic outcomes remains limited. This study examined how engagement patterns and incentives impact academic outcomes in a gamified environment to determine whether a formative question bank
