Diversity and random forest models of oral microbiomes in periodontal health using publicly available data

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Evidence on the 16S metabarcoding of supragingival, subgingival, and salivary microbiomes in periodontal health remains limited. We aimed to analyze the diversity and potential of machine‐learning models of supragingival, subgingival, and salivary microbiomes in periodontal health. Methods A total of 848 samples (supragingival = 210;

Artificial tooth selection: Could digital photographs be helpful?

open access: yesProtetyka stomatologiczna, 2005
Introduction: Digital photography is almost available to everybody. Proper artificial tooth selection is very important for aesthetic consideration of prosthetic appliance. Aim of this study: was to examine possibility of calculating the width of a missing central incisor using digital photographs as well as to determine best camera-object distance on ...

A retrospective cohort study comparing periodontal regeneration using fibroblast growth factor‐2 versus autologous bone graft

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Fibroblast growth factor‐2 (FGF‐2) is a novel agent utilized in periodontal regeneration therapy. However, its clinical efficacy compared with autologous bone graft (ABG), a long‐established treatment, remains unclear. This study aimed to compare the clinical outcomes of FGF‐2 and ABG and to assess the impact of patient background ...

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging in Vivo

open access: yesLaser &Photonics Reviews, EarlyView.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

Study on the Shape Memory Performance of 4D‐Printed Auxetic Cellular Structures with Energy Absorption Application

open access: yesMacromolecular Materials and Engineering, EarlyView.
4D‐printed auxetic cellular structures made from PETG demonstrate almost complete recovery of shape and mechanical properties after repeated loading. Two strategies successfully addressed the low shape‐fixity issue, the primary limitation of cold programming.

Lions as Bone Accumulators? Exploring Multi‐Predator Contributions to the Olduvai Carnivore Site (OCS) (Tanzania) Through AI and Metric Analyses

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...

On the spatial clustering of behavioural phenotypes: matching movement tactics with landscape structure in a large herbivore

open access: yesOikos, EarlyView.
In the wild, individuals consistently differ in movement and space use behaviours, depending on their personality. This variation can lead to personality–habitat associations and spatial structuring, potentially generating individual niche segregation.
