Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Characterization of Two Specific Cases with New Operators in Ideal Topological Spaces

open access: yesJournal of New Theory
This research deals with new operators $\wedge_{\Gamma}$, $\veebar_{\Gamma}$, and $\barwedge_{\Gamma}$, defined using $\Gamma$-local closure function and $\Psi_{\Gamma}$-operator in ideal topological spaces.

On Bisimilarity for Quasi-discrete Closure Spaces [PDF]

open access: yesLogical Methods in Computer Science
Closure spaces, a generalisation of topological spaces, have shown to be a convenient theoretical framework for spatial model checking. The closure operator of closure spaces and quasi-discrete closure spaces induces a notion of neighborhood akin to that

On Connectedness via Closure Operators [PDF]

open access: yesApplied Categorical Structures, 2001
The author enriches the investigation of categorical connectedness properties (i.e., of left- and right-constant subcategories) induced by categorical closure operators, by defining and investigating for each category \({\mathcal X}\), equipped with a closure operator \(c\), the subcategories of \(c\)-coarse and \(c\)-fine objects.

FUZZY G-CLOSURE OPERATORS [PDF]

open access: yesCommunications of the Korean Mathematical Society, 2003
Summary: We introduce a fuzzy g-closure operator induced by a fuzzy topological space in view of the definition of \textit{A.P.Šostak} [Rend. Circ. Mat. Palermo, II. Ser. Suppl. 11, 89-103 (1985; Zbl 0638.45007)]. We show that it is a fuzzy closure operator. Furthermore, it induces a fuzzy topology which is finer than a given fuzzy topology.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Rota-Baxter Operators of Weight Zero on CayleyDickson Algebra with Matrix Images

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
Rota-Baxter operators present a natural generalization of integration by parts formula for the integral operator. We consider Rota-Baxter operators of weight zero on split octonion algebra over a field of characteristic not 2.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
