When is a regular local ring a locality?
Journal of Algebra, 1988 The author proves constructively and clearly the following nice fact: A normal local domain \((A,M)\) containing a field \(K\) is essentially of finite type over \(K\) if and only if: (1) the residue field \(A/M\) is a finitely generated extension of \(K\); (3) the quotient field \(L\) of \(A\) is a finitely generated extension of \(K\); and (2) \(\dim(

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Local Cohomology Modules and Relative Cohen-Macaulayness
Discussiones Mathematicae - General Algebra and Applications, 2018 Let (R, 𝔪) denote a commutative Noetherian local ring and let M be a finite R-module. In this paper, we study relative Cohen-Macaulay rings with respect to a proper ideal 𝔞 of R and give some results on such rings in relation with Artinianness, Non ...

On the Structure of Complete Local Rings [PDF]
Nagoya Mathematical Journal, 1950 The concept of a local ring was introduced by Krull [2], who defined it as a Noetherian ringR(we say that a commutative ringRis Noetherian if every ideal inRhas a finite basis and ifRcontains the identity) which has only one maximal idealm. If the powers of m are defined as a system of neighbourhoods of zero, thenRbecomes a topological ring satisfying ...

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

On Generalized Regular Local Ring
Science Journal of University of Zakho, 2015 A ring R is called a generalized Von Neumann regular local ring (GVNL-ring) if for any a∈R, either a or (1-a) is π-regular element. In this paper, we give some characterization and properties of generalized regular local rings.

PLoS ONE, 2016 Provenance studies are an increasingly important analog for understanding how trees adapted to particular climatic conditions might respond to climate change. Dendrochronological analysis can illuminate differences among trees from different seed sources

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer
Molecular Oncology, EarlyView.COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

Coefficient subrings of certain local rings with prime-power characteristic
International Journal of Mathematics and Mathematical Sciences, 1995 If R is a local ring whose radical J(R) is nilpotent and R/J(R) is a commutative field which is algebraic over GF(p), then R has at least one subring S such that S=∪i=1∞Si, where each Si, is isomorphic to a Galois ring and S/J(S) is naturally isomorphic ...
