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

VIEW, 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.

DualSS: A Dual‐Diffusion Synthetic Sampling Framework for Screening Fatty Liver Severity With Class‐Imbalanced Tongue Images

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Fatty liver disease (FLD) is a prevalent chronic condition that can progress to clinically significant liver injury if left untreated. Given its high prevalence, FLD poses a substantial public health burden. Traditional Chinese medicine suggests that the appearance of tongue reflects hepatic and metabolic status, enabling artificial ...

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

Methods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

Powdered hibiscus anthocyanin‐nanofibril complexes as natural colourants: Stability and application in yoghurt and soft candy

Coloration Technology, EarlyView.
Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

Spectral Transforms as a Tool to Optimize Digital Phenotyping in Biological Images

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Modern livestock breeding has mastered genotyping. Genome‐wide association studies, genomic selection, and SNP arrays enable genetic merit prediction at lower cost. However, phenotyping remains the bottleneck, as manual measurement is slow, expensive, subjective, and unable to capture spatial or temporal trait organization. Digital phenotyping

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Performance in Gingival Shade Selection Among Undergraduate Dental Students According to Gender: A Pilot Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Statement of Problem Color perception is a subjective process that can vary considerably among individuals. However, limited research has examined gingival shade selection according to observer gender. Objectives According to observer gender and gingival site, the objectives of this study were: (1) to compare subjective visual gingival shade ...

Influence of Illumination Conditions and Cross‐Polarization on DSLR‐Based Clinical Tooth Color Assessment: A Comparison With Spectrophotometric Measurements

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Aim To evaluate the influence of different illumination systems and cross‐polarization on tooth color determination using DSLR photography, and to assess the agreement between photographic methods and spectrophotometric measurements. Materials and Methods Thirty‐one participants (62 maxillary central incisors) were included. Color measurements

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms

Journal of Microscopy, EarlyView.
Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...
