AIM To investigate the interactions of the DNA repair gene excision repair cross complementing group 5 (ERCC5) and the metabolic gene glutathione S-transferase pi 1 (GSTP1) and their effects on atrophic gastritis (AG) and gastric cancer (GC) risk. METHODS Seven ERCC5 single nucleotide polymorphisms (SNPs) (rs1047768, rs2094258, rs2228959, rs4150291, rs4150383, rs751402, and rs873601) and GSTP...

Pairwise and random addition processes are ordinarily indistinguishable in hydrogenation reactions. The distinction becomes important only when the fate of spin correlation matters, such as in parahydrogen-induced polarization (PHIP). Supported metal catalysts were not expected to yield PHIP signals given the rapid diffusion of H atoms on the catalyst surface and in view of the sequential stepw...

In this paper, some new types of regularity axioms, namely pairwise quasi-regular, semi-regular, pseudo regular and are defined studied in both ech fuzzy soft bi-closure spaces ( bicsp’s) their induced bitopological spaces. We also study the relationships between them. show that all these hereditary property is satisfied under closed fs bi-csubsp . Furthermore, we define normality semi-normal, ...

A bstract On-shell methods are particularly suited for exploring the scattering of electrically and magnetically charged objects, which there is no local Lorentz invariant Lagrangian description. In this paper we show how to construct a Lorentz-invariant S -matrix particles, without ever having refer Dirac string. key ingredient revision our fundamental understanding multi-particle representati...

We study the ideals of the rational cohomology ring of the Hilbert scheme X [n] of n points on a smooth projective surface X . As an application, for a large class of smooth quasi-projective surfaces X , we show that every cup product structure constant of H∗(X ) is independent of n; moreover, we obtain two sets of ring generators for the cohomology ring H∗(X ). Similar results are established ...

In the crystal of the title mol-ecular salt, C(7)H(7)N(2) (+)·Br(-), the cations form inversion dimers via weak pairwise C-H⋯N hydrogen bonds; their mean planes are separated by 0.292 (6) Å. Weak C-H⋯Br inter-actions involving all of the remaining H atoms tie the cations and anions together into sets of inter-penetrating sheets. The title compound is isostructural with its iodide analogue.

A graph H is an induced minor of a graph G if it can be obtained from an induced subgraph of G by contracting edges. Otherwise, G is said to be H-induced minor-free. Robin Thomas showed that K4-induced minor-free graphs are well-quasi-ordered by induced minors [Graphs without K4 and well-quasi-ordering, Journal of Combinatorial Theory, Series B, 38(3):240 – 247, 1985]. We provide a dichotomy th...
