A generalization of reversible rings
, 2014 In this paper, we introduce a class of rings which is a generalization of reversible rings. Let R be a ring with identity. A ring R is called central reversible if for any a,b א R, ab=0 implies ba belongs to the center of R. Since every reversible ring is central reversible, we study sufficient conditions for central reversible rings to be reversible ...

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^\

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

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 ...

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 \(x,y\in R\), \(F(xy)=F(y)x+yd(x)\),

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.
