f-Contractive multivalued maps and coincidence points [PDF]

Journal of Inequalities and Applications, 2013
The paper presents a coincidence point theorem and a common fixed point theorem for a single-valued mapping \(f:X\to X\) and a multi-valued one \(T:X\to 2^X\) using an \(f\)-contractive condition for \(T\). The contractive condition is given in terms of an \(\omega\)-distance in the sense of \textit{T. Suzuki} and \textit{W. Takahashi} [Topol.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Some strong coupled coincidence and coupled best proximity results on complete metric spaces

Journal of Inequalities and Applications
In this paper, the concept of Wardowski’s class of contraction is integrated with that of g-coupling to define some F-contractive type g-couplings. We establish existence results for a coupled coincidence point, a strong coupled coincidence point, and a ...

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

FEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

On coincidence points of generalized contractive pair mappings in convex metric spaces [PDF]

Journal of Hyperstructures, 2015
We obtain a contractive condition for the existence of coincidence points of a pair of self-mappings defined on a nonempty subset of a complete convex metric space. Moreover, we show that weakly compatible pairs have at least a common fixed point.

Second Virial Coefficient of Anyons without Hard Core

, 1997
We calculate the second virial coefficient of anyons whose wave function does not vanish at coincidence points. This kind of anyons appear naturally when one generalizes the hard-core boundary condition according to self-adjoint extension method in ...

Coincidence and fixed points of nonlinear Hybrid contractions [PDF]

International Journal of Mathematics and Mathematical Sciences, 1987
In this Der, we show the existence of solutions of functional equations fx ∈ sx∩tx and x=fx ∈ sx∩Tx under certain contraction and asymptotic regularity conditions, where f, S and T are single‐valued and multl‐valued mappings on a metric space, respectively.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.
