Inosine triphosphate pyrophosphatase activity as a potential predictor of methotrexate remission in juvenile idiopathic arthritis

open access: yesArthritis &Rheumatology, Accepted Article.
Background Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients don't respond. Low inosine‐triphosphate‐pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated ITPA role and the underlying mechanisms in vitro.

On an anti‐Ramsey property of Ramanujan graphs [PDF]

open access: yesRandom Structures & Algorithms, 1995
AbstractIf G and H are graphs, we write G→ H (respectively, G→ TH) if for any proper edge‐coloring γ of G there is a subgraph H' ⊂ G of G isomorphic to H (respectively, isomorphic to a subdivision of H) such that γ is injective on E(H'). Let us write Cl for the cycle of length l. Spencer (cf.

Multi‐omic profiling reveals immune cell priming signature linked to lupus prognosis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Systemic lupus erythematosus (SLE) is a multi‐organ disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.

Large rainbow matchings in large graphs [PDF]

open access: yes, 2011
A \textit{rainbow subgraph} of an edge-colored graph is a subgraph whose edges have distinct colors. The \textit{color degree} of a vertex $v$ is the number of different colors on edges incident to $v$. We show that if $n$ is large enough (namely, $n\geq

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Medicare Part D and Hospital Admissions due to Antimicrobial Resistance

open access: yesHealth Economics, EarlyView.
ABSTRACT Antimicrobial resistance (AMR) has been increasing rapidly in the United States despite government efforts to contain its spread. Both under‐utilization and overuse of prescribed antimicrobials contribute to rising resistance. The introduction of Medicare Part D in 2006 expanded prescription drug coverage for the elderly, including coverage ...

Anti-Ramsey properties of random graphs

open access: yesJournal of Combinatorial Theory, Series B, 2010
We call a coloring of the edge set of a graph G a b-bounded coloring if no color is used more than b times. We say that a subset of the edges of G is rainbow if each edge is of a different color. A graph has property A(b,H) if every b-bounded coloring of its edges has a rainbow copy of H .

Anti-Ramsey Number of Edge-Disjoint Rainbow Spanning Trees [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2020
An edge-colored graph $G$ is called rainbow if every edge of $G$ receives a different color. The anti-Ramsey number of $t$ edge-disjoint rainbow spanning trees, denoted by $r(n,t)$, is defined as the maximum number of colors in an edge-coloring of $K_n$ containing no $t$ edge-disjoint rainbow spanning trees.

Monochromatic Graph Decompositions Inspired by Anti-Ramsey Theory and Parity Constraints

open access: yesMathematics
We open here many new tracks of research in anti-Ramsey Theory, considering edge-coloring problems inspired by rainbow coloring and further by odd colorings and conflict-free colorings. Let G be a graph and F any given family of graphs. For every integer

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward
