The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Coincidence and fixed points for compatible and relatively nonexpansive maps
International Journal of Mathematics and Mathematical Sciences, 1993 The concept of relatively nonexpansive maps is introduced. Fixed point and coincidence results for families of four self maps of metric spaces are obtained.

COMMON FIXED POINTS OF COMPATIBLE MAPPINGS
Demonstratio Mathematica, 1993 Extending results of the author [ibid. 23, No. 1, 213-218 (1990; Zbl 0731.54030)] and of \textit{B. E. Rhoades} [Some fixed point theorems for pairs of mappings, Jñānābha 15, 151-156 (1985)], some common fixed point theorems are established. Four mappings are involved satisfying a suitable expansive inequality in a complete metric space and a pairwise ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

On a fixed point theorem of Fisher and Sessa
International Journal of Mathematics and Mathematical Sciences, 1990 A fixed point theorem of Fisher and Sessa is generalized by replacing the requirements of commutativity and nonexpansiveness by compatibility and continuity respectively.

FEBS 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.

Common Fixed Point Theorems in Menger Probabilistic Quasimetric Spaces
Fixed Point Theory and Applications, 2009 We consider complete Menger probabilistic quasimetric space and prove common fixed point theorems for weakly compatible maps in this space.

Weak contractive integral inequalities and fixed points in modular metric spaces
Journal of Inequalities and Applications, 2016 Branciari (Int. J. Math. Math. Sci. 29(9):531-536, 2002) gave an interesting supplement of Banach’s contraction principle for an integral-type inequality.

COINCIDENCE POINTS OF WEAKLY COMPATIBLE MAPPINGS [PDF]
Bulletin of the Korean Mathematical Society, 2008 We present coincidence points and common fixed point re- sults for (f, g)-contractive mapping and (f, g)-nonexpansive mappings. Our results generalize and complement various known results existing in the literature.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
