GENERAL FIXED POINT THEOREMS FOR WEAKLY COMPATIBLE MAPS
Demonstratio Mathematica, 2005 Summary: The purpose of this note is to use general expansive and conditions minimal type commutativity without continuity requirements to prove some fixed point theorems. The theorems extend known results from the class of compatible continuous expansive maps to a wider class of mappings.

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 ...

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.

Common Fixed Point Theorems for Weakly Compatible Mappings
Rocky Mountain Journal of Mathematics, 2003 Let \((X,d)\) be a metric space, \(F\), \(G: X \multimap X\) be set-valued mappings and \(I\), \(J:X\to X\) two mappings. The author gives metric conditions which imply that there exists \(x \in X\) such that \(F(x)=G(x)=\{x\}\) and \(I(x)=J(x)=x\).

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 ...

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.

AIMS Mathematics, 2022 In this manuscript, we induced several vivid common fixed point theorems for four maps in the setting of complete multiplicative $ {G_{\boldsymbol{M}}}- $metric space via various contractive conditions such as $ \Delta $-implicit contractions.

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 ...

Presic Type Fixed Point Theorem for Four Maps in Metric Spaces
Journal of Mathematics, 2016 We obtained a Presic type fixed point theorem for two pairs of jointly 2k-weakly compatible maps in metric spaces. We also have given an example to illustrate our main theorem.

Fractal and Fractional, 2022 The aim of this paper is to obtain some new results about common fixed points. Our results use weaker conditions than those previously used. We have relaxed the conditions for commutating pair mappings and compatible mappings of the type (A), which were ...
