NKCC1: A key regulator of glioblastoma progression
Molecular Oncology, EarlyView.Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Positive linear operators continuous for strict topologies [PDF]
Proceedings of the American Mathematical Society, 1974 If A A is an S W SW algebra of real-valued functions on a set X X equipped with the weak topology for A A , and if A A separates its zero sets, then many results valued for C b (

Insights into a long life without cancer: The case of the bowhead whale
Molecular Oncology, EarlyView.Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Towards the best constant in front of the Ditzian-Totik modulus of smoothness
Journal of Inequalities and Applications, 2016 We give accurate estimates for the constants K ( A ( I ) , n , x ) = sup f ∈ A ( I ) | L n f ( x ) − f ( x ) | ω σ 2 ( f ; 1 / n ) , x ∈ I , n = 1 , 2 , … , $$ K\bigl(\mathcal{A}(I), n, x\bigr)=\sup_{f\in\mathcal{A}(I)}\frac{|L_{n} f(x)-f(x)|}{\omega_ ...

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Positive Linear Operators and Entropies
Approximation Theory and Special FunctionsThe study of positive linear operators is closely linked to the study of probability distributions. In this paper, we investigate the relationship between classical positive linear operators, commonly used in Approximation Theory, and the entropies associated with probability distributions.

Molecular Oncology, EarlyView.A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

Notes On The Non Linear Operator Equation I AXAX n  ï€*
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2016 Necessary and sufficient conditions for the operator equation I AXAX n  ï€* , to have a real positive definite solution X are given. Based on these conditions, some properties of the operator A as well as relation between the solutions X ...
