Phosphomimetic statherin‐derived peptide protects against intrinsic enamel erosion independently of sodium trimetaphosphate

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the effect of a phosphomimetic statherin‐derived peptide (DDSt15), alone or combined with sodium trimetaphosphate (TMP), on the protection against initial enamel erosion. A total of 102 bovine enamel samples (4 × 4 mm2) were prepared and randomly allocated into six groups (n = 17): deionized water (negative ...

Additively manufactured water‐washable resin dies cleaned with nonhazardous solutions: Can dimensional and positional trueness be ensured?

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to evaluate the dimensional and positional trueness of additively manufactured (AM) removable dies in water‐washable (WW) resins and cleaned using different post‐processing solutions (98% isopropyl alcohol [IPA], methyl ether solvent [MES], and water).

Direct Regioselective para‐Fluorination via I(I)/I(III) Catalysis

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
A direct, para‐selective fluorination by I(I)/I(III) catalysis is disclosed that does not require substrate pre‐functionalization. This strategy leverages the Leonard link inherent to phenylpropanoate and phenylpropanamides to promote a spirocyclization/para‐selective sequence. The C3‐side chain maps onto a range of common drug scaffolds and allows the

A Wild Emmer Wheat B3 Transcription Factor Regulates Seed Growth and Nutrient Allocation

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Seed weight (SW) and nutrient allocation are key determinants of yield and grain quality in wheat, yet the regulatory basis of naturally occurring variation in these traits remains poorly resolved. Wild emmer wheat (Triticum dicoccoides), the progenitor of modern wheat, retains extensive eco‐geographically structured genetic diversity that was

Reaction Environment Engineering for Selective C3+ Formation in CO2 Electroreduction: Progress and Perspectives

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
This work focuses on how to improve the selectivity and activity of electrocatalytic CO2 reduction to C3+ products, by the integration of electrocatalyst and electrolyte co‐design. We summarize key C3+ formation mechanisms and provide a comprehensive reaction network through thermodynamic analysis.

Long‐term stability of vertical bone augmentation in implant dentistry: A domain‐based review

open access: yesPeriodontology 2000, EarlyView.
Abstract Objectives Vertical ridge deficiency remains one of the most challenging conditions in preimplant surgery. Several techniques aim to restore lost vertical alveolar height, each with specific indications and limitations. Although these procedures often yield favorable short‐term outcomes with stable bone levels, their long‐term performance is ...

Shaping Arab Identity Through the Beautiful Game: A Heterotopic Analysis of the 2022 World Cup

open access: yesStudies in Ethnicity and Nationalism, EarlyView.
ABSTRACT This study examines how the 2022 FIFA World Cup in Qatar functioned as a heterotopic space through which Middle Eastern and North African (MENA) identities were publicly articulated, negotiated and made visible. Drawing on Foucault's notion of heterotopia and Lefebvre's understanding of space as socially produced, the paper approaches the ...

Macrocyclic Receptor Molecules for Guanidinium Cations. 2. Synthesis and X-Ray Structures of 2,6-Pyrido Crown Ethers and their Guanidinium Complexes

open access: yes, 1986
2,6-Pyrido crown ethers I (n = 0-6) were synthesized and their complexation with guanidinium salts studied by using two phase extn. expts. The crystal and mol. structures of the complexes and the free 2,6-pyrido-24-crown-8 were detd. by x-ray crystallog.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...
