Neurons differentially upregulate type 2 immune cytokines and interleukin-4 receptor subtypes during neuroinflammation

Acta Neuropathologica Communications
Although numerous studies demonstrate beneficial effects of exogenous interleukin-4 (IL-4) in different central nervous system (CNS) disease models, little is known about the expression of IL-4 and its receptor (IL-4R) system in neurons.

Radio mean labeling of a graph

AKCE International Journal of Graphs and Combinatorics, 2015
A Radio Mean labeling of a connected graph G is a one to one map f from the vertex set V(G) to the set of natural numbers N such that for two distinct vertices u and v of G, d(u,v)+⌈f(u)+f(v)2⌉≥1+diam(G).
