Common Fixed-Point and Fixed-Circle Results for a Class of Discontinuous F-Contractive Mappings
Mathematics, 2022 The exploration of contractive inequalities which do not imply the continuity of the mapping at fixed points was an interesting open problem for quite some time.

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases
FEBS Letters, EarlyView.The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Common fixed point theorems in Menger spaces
International Journal of Mathematics and Mathematical Sciences, 2006 We proved two common fixed point theorems for four self-mappings and two set-valued mappings with φ-contractive condition in a Menger space.

Relational Meir-Keeler Contractions and Common Fixed Point Theorems
Journal of Function Spaces, 2022 In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.

Common fixed point theorems for two mappings in $b$-metric-like spaces [PDF]
arXiv, 2023 In this paper, we give some requirements under which two self-mappings have a common fixed point in $b$-metric-like spaces.

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

General Common Fixed Point Theorems and Applications
Journal of Applied Mathematics, 2012 The main result is a common fixed point theorem for a pair of multivalued maps on a complete metric space extending a recent result of Đorić and Lazović (2011) for a multivalued map on a metric space satisfying Ćirić-Suzuki-type-generalized contraction.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

On a fixed point theorem of Greguš
International Journal of Mathematics and Mathematical Sciences, 1986 We consider two selfmaps T and I of a closed convex subset C of a Banach space X which are weakly commuting in X, i.e.‖TIx−ITx‖≤‖Ix−Tx‖ for any x in X,and satisfy the inequality‖Tx−Ty‖≤a‖Ix−Iy‖+(1−a)max{‖Tx−Ix‖,‖Ty−Iy‖}for all x, y in C, where ...

AIMS Mathematics, 2023 In this article, we use the concept of proximity spaces to prove common fixed point results for mappings satisfying generalized ($ \psi $, $ \beta $)-Geraghty contraction type mapping in partially ordered proximity spaces.
