GK PUA Domain Modulates Cables, Cooperativity, and Proline Feedback

open access: yesAggregate, Volume 7, Issue 8, August 2026.
EcGK tetramers hierarchically assemble into metabolic filaments and bundle into metabolic cables. Upon substrate binding, this dynamic equilibrium shifts from inactive cables to active tetramers to drive catalysis; meanwhile the inhibitor proline stabilizes an X‐shaped conformation, redirecting assembly toward filaments to enable efficient feedback ...

Halide/Pseudohalide Anion Regulation of Polar Structure and Glass‐Forming Ability Toward Polar Hybrid Glass‐Ceramic

open access: yesAggregate, Volume 7, Issue 8, August 2026.
Systematic anion engineering from halide to pseudohalide (Cl− → Br− → I− → NCS−) in a family of cadmium(II)‐based organic‐inorganic hybrids drives a progressive transition from centrosymmetric to polar structure, depresses melting point, reduces fragility index, and enhances glass‐forming ability, ultimately affording a polar hybrid glass‐ceramic with ...

The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate Into Better Assisted Reproductive Technology Outcomes?

open access: yesJournal of Ultrasound in Medicine, Volume 45, Issue 8, Page 1647-1653, August 2026.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...

Nanostructure and Collagen‐Stimulating Activity of Cationic Pentapeptide Lipopeptides

open access: yesJournal of Peptide Science, Volume 32, Issue 8, August 2026.
The self‐assembly in aqueous solutions, cytocompatibility and collagen production of lipopeptide C16–KTTKS (C16: hexadecyl) and a variant with arginine substitution for lysine, C16–RTTRS, are compared. ABSTRACT The self‐assembly in aqueous solutions, cytocompatibility, and collagen production of lipopeptide C16–KTTKS and a variant with arginine ...

Water‐Mediated Phosphoryl Wires Stabilize Pathological Tau Fibrils

open access: yesAngewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Extended 1D phosphoryl “wires” stabilize in‐register amyloid tau fibrils, as demonstrated by multiple‐quantum spin‐counting NMR, TEM, and MD simulations, using fibrils of tau peptide jR2R3‐P301L (tau295–313) with phosphorylation at S305 or Y310. ABSTRACT Hyperphosphorylation of tau is a hallmark of tauopathies, with specific phosphorylation sites ...
