Defining the role of αC helix interactions in the activation of the integrin αI domain

The FEBS Journal, EarlyView.
The α2I domain of the α2β1 integrin contains a distinctive αC helix and a conserved Arg288‐Glu318 ion pair that stabilizes the closed state of the domain. Disruption of this ion pair in the activated α2I variant unwinds the αC helix, which allows interaction with additional collagen‐binding sites increasing collagen binding.

The Sextuple Helix Innovation Model: Positioning Generative AI as an Epistemic Agent in Creative and Sustainable Knowledge Economies

Social Sciences
This paper introduces the Sextuple Helix Innovation Model as an extension of the Quintuple Helix Innovation Model by Carayannis and Campbell. The epistemic perspective considers the understanding of generative AI (GenAI) as a sixth helix of knowledge ...

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

New Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Accuracy of cone‐beam computed tomography in imaging the components of the periodontal phenotype

Periodontology 2000, EarlyView.
Abstract The components and dimensions of the periodontal and peri‐implant phenotype have a high relevance in contemporary dental research and should be taken into consideration in the decision‐making process in the management of a variety of clinical scenarios to optimize the outcomes of therapy.

Gender Equity, internationalization and quintuple helix:

Journal of International Students
As higher education institutions (HEIs) seek to align with Sustainable Development Goals (SDGs), integrating diversity, equity, and inclusion (DEI) into internationalization strategies has become increasingly central. In this study, we analyze 209 university strategic plans, 86 from Japan (2022–2027) and 123 from Türkiye (2019–2023), to examine how ...

Old dog, new trick: Charybdotoxin as a novel ryanodine receptor blocker

The Journal of Physiology, EarlyView.
Abstract figure legend The peptide toxin charybdotoxin (ChTx) from the scorpion Leiurus quinquestriatus was tested on single‐channel currents of the ryanodine receptor incorporated into planar lipid bilayers. The structure–function relationship of ChTx was investigated using toxin variants generated by isosteric substitutions of the basic amino acids ...

Three New Calcium Formate Reference Materials for δ13C Measurements and a Redetermination of the R(13C/12C) Ratio for VPDB Based on Proton Nuclear Magnetic Resonance Measurements

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Isotope ratio mass spectrometry (IRMS) and proton nuclear magnetic resonance (1H NMR) spectroscopy are independent techniques for determining the isotope ratio R(13C/12C) in organic compounds. However, the lack of suitable reference materials has limited intercalibration of results from these methods.
