Physical properties and cellular responses of gelatin methacryloyl bulk hydrogels and highly ordered porous hydrogels

open access: yesFrontiers in Soft Matter, 2023
Protein-based hydrogels hold a high content of water in their three-dimensional (3D) network structure and exhibit innate biological activities as well as soft tissue-like mechanical properties, resulting in being highly applicable to various tissue ...

Orders in quadratic fields, I

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1993
In Part I [ibid. 69, 45-48 (1993; Zbl 0795.11056)], the author gave a criterion for an arbitrary order to have class group generated by ambiguous ideals and also made a conjecture related to that criterion. Afterwards, however, counterexamples to the conjecture were found [cf. Part III, ibid. 70, 176-181 (1994; Zbl 0809.11064)].

A Facile Route to Synthesis of Hierarchically Porous Carbon via Micelle System for Bifunctional Electrochemical Application

open access: yesFrontiers in Chemistry, 2021
Well-ordered hierarchically porous carbon (HPC) nanomaterials have been successfully synthesized by a facile, efficient, and fast heated-evaporation induced self-assembly (HISA) method.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Covalent Organic Frameworks for Chemical and Biological Sensing

open access: yesMolecules, 2022
Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with polygonal porosity and highly ordered structures. The most prominent feature of the COFs is their excellent crystallinity and highly ordered modifiable one ...

Strong ordering of ∗-fields

open access: yesJournal of Algebra, 1986
This paper is the third in a series of three papers (so far) in which the author discusses orderings on *-fields [the others are J. Algebra 46, 207--219 (1977; Zbl 0359.12023) and Trans. Am. Math. Soc. 262, 219--243 (1980; Zbl 0482.12009)]. A field (i.e.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Weakly ∗-ordered ∗-fields

open access: yesJournal of Pure and Applied Algebra, 1995
Let \(D\) be a division ring with involution *, center \(F\) and \([D : F] < \infty \). Since furthermore \(D\) is required to have a weak *-ordering, only the following two cases occur: (1) \((D,*)\) is a standard quaternion-algebra or (2) \([D : F]\) is odd.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
