IGFBP5 Restores Endometrial Receptivity and Rescues Implantation Failure in Polycystic Ovary Syndrome

Advanced Science, Volume 13, Issue 27, 13 May 2026.
Impaired endometrial receptivity contributes to the poor pregnancy outcomes in women with PCOS. The authors found that decreased endometrial IL‐22 levels and disrupted STAT3‐IGFBP5 signaling pathway contributed to impaired endometrial receptivity. Supplementation with IL‐22 or IGFBP5 exerts a protective effect on implantation failure in PCOS‐like mice,

Targeting SPP1‐CD44‐Hedgehog Axis Elicits Therapeutic Effects in Hepatocellular Carcinoma by Suppressing Intratumoral Fibrosis

Cancer Science, Volume 117, Issue 3, Page 670-682, March 2026.
SPP1 was identified as a key driver of intratumoral fibrosis and hepatocellular carcinoma (HCC) progression through transcriptomic, histological, and functional analyses. Mechanistically, SPP1 promotes HSC activation and fibrosis via the SPP1–CD44–GLI1 axis, and pharmacologic inhibition of Hedgehog signaling effectively reduces tumor growth and ...

The Picard–Mann iteration with s-convexity in the generation of Mandelbrot and Julia sets [PDF]

, 2021
In recent years, researchers have studied the use of different iteration processes from fixed point theory in the generation of complex fractals. For instance, the Mann, Ishikawa, Noor, Jungck–Mann and Jungck–Ishikawa iterations have been used.

Fixed point approximation under Mann iteration beyond Ishikawa [PDF]

, 2020
summary:Consider the Mann iteration $x_{n+1} = ( 1 - \alpha_n ) x_n + \alpha_n Tx_n$ for a nonexpansive mapping $T\colon K \to K$ defined on some subset $K$ of the normed space $X$.

Modified Fast Inertial‐Type Krasnosel’skii‐Mann Iterative Scheme Involving Asymptotically Nonexpansive Mapping

Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.
It is our aim to propose a new iterative algorithm with an inertial term involving asymptotically nonexpansive mapping in the framework of Hilbert spaces. Let T : H⟶H be asymptotically nonexpansive mapping with F(T) ≠ ∅ ∅ and let xnn≥0 be defined by xn+1 = σnzn + bn(Tnσnzn − σnzn) + εn, ∀n ≥ 1.

Convergence of Picard–CR Iterative Algorithm and Applications

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In applied mathematics, graph theory (GT) is a notably compelling area of study. In the last 50 years, the number of mathematicians making contributions to research in this field has consistently increased. This rising interest is mainly a result of the significant real‐world applications it offers.

On a New Faster Implicit Fixed Point Iterative Scheme in Convex Metric Spaces

Journal of Function Spaces, 2015
The purpose of this paper is to consider a new implicit iteration and study its strong convergence, stability, and data dependence. It is proved through numerical examples that newly introduced iteration has better convergence rate than well known ...

On the Fixed Points for Ćirić–Reich–Rus Contractive Type Mappings in Complex Valued Metric Spaces

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this article, we investigate Ćirić–Reich–Rus contractive type mappings with rational inequality in complex‐valued metric spaces (C‐VMSs) and establish some fixed point results. We establish the well‐posedness of the considered problem and examine the relation between the fixed points of the mapping and those of its iterates, confirming the periodic ...

Convergence Behavior of the F∗ Algorithm: Strong and Weak Results for Nonexpansive Mappings

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study examines the strong and weak convergence of the F∗ iterative approach to the fixed point of a nonexpansive mapping in the context of a Banach space. This work shows improved rate and efficiency of convergence. Furthermore, we proved that F∗ iterative algorithm converges to a fixed point faster than Picard, Mann, S, and Varat iterative ...

On the equivalence of Picard, Mann and Ishikawa iterations for a class of quasi-contractive operators

, 2008
We show that the Picard, Mann and the Ishikawa iterations are equivalent when applied to a class of quasi-contractive operators. This result generalises that of Soltuz among others. JONAMP Vol. 11 2007: pp.
