Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Reversible Self-Dual Codes Over the Ring F2 +
IEEE AccessIn this study, we introduce bisymmetric self-dual codes over the finite field ${\mathbb F}_{2}$ of order two. We developed a method to generate binary bisymmetric self-dual codes from a small-length bisymmetric self-dual code by increasing its length ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Insight into the mechanism of reversible ring-opening of 1,3‑Benzoxazine with thiols
, 2022 S.4050-4055The reversible ring-opening addition and fragmentation reaction of p-cresol-based N-phenylbenzoxazine with aliphatic and aromatic thiols was investigated in solvent-mediated and solvent-free reactions.

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 Over finite local Frobenius non-chain rings of length 5 and nilpotency index 4 and when the length of the code is relatively prime to the characteristic of the residue field of the ring, the structure of the dual of γ-constacyclic codes is established ...

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Reverse order laws in rings with involution
Rocky Mountain Journal of Mathematics, 2014 In a ring with involution, \(a^\#\) stands for the group inverse, and \(a^\dagger\) for the Moore-Penrose inverse of \(a\). Various equivalent conditions to each of a number reverse order laws are presented. Among these laws are \((ab)^\#=b^\#(a^\dagger abb^\#)^\#a^\dagger\), \((ab)^\#=b^*(a^\#abb^*)^\#a^\#\), \((ab)^\#=b^\dagger a^\#\), \(b^\#(a^*abb^\

Generalized reverse derivations on semiprime rings
Siberian Mathematical Journal, 2015 Let \(R\) be a semiprime ring, \(I\) a nonzero ideal of \(R\) and \(d\) a reverse derivation of \(R\), that is \(d\colon R\to R\) is additive and for all \(x,y\in R\), \(d(xy)=d(y)x+yd(x)\). If also \(F\colon R\to R\) is additive then call the pair \((F,d)\) an \(l\)-generalized reverse derivation of \(R\) if for all \(x,y\in R\), \(F(xy)=F(y)x+yd(x)\),

ON PROPERTIES RELATED TO REVERSIBLE RINGS [PDF]
Bulletin of the Korean Mathematical Society, 2015 We study the connections between idempotents and zero- divisors in several kinds of ring theoretic properties. We next study sev- eral ring theoretic properties and examples related to reversible rings.
