The article highlighted in this issue is “Dizocilpine Improves Beneficial Effects of Cholinergic Antagonists in Anticholinesterase-Treated Mice,” by Andrzej Dekundy, Rafal M. Kaminski, and Waldemar A. Turski (pp. 289–295). It explores the relationship between cholinergic and N-methyl-D-aspartate (NMDA) receptors as mediators of anticholinesterase toxicity. The following review summarizes these ...

21 N-Methyl-D-aspartate (NMDA) receptors are of critical importance for 22 locomotion in the developing neonatal spinal cord in rats and mice. However, due to 23 profound changes in the expression of NMDA receptors in development between the 24 neonatal stages and adulthood, it is unclear whether NMDA receptors are still an 25 important component of locomotion in the adult rodent spinal cord. T...

 Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted‎, ‎it is called a right co-$(n,d)$-ring if every right $R$-module is $(n‎, ‎d)$-projective‎. ‎$R$...

‎Let $G$ be a non-abelian group and let $Gamma(G)$ be the non-commuting graph of $G$‎. ‎In this paper we define an equivalence relation $sim$ on the set of $V(Gamma(G))=Gsetminus Z(G)$ by taking $xsim y$ if and only if $N(x)=N(y)$‎, ‎where $ N(x)={uin G | x textrm{ and } u textrm{ are adjacent in }Gamma(G)}$ is the open neighborhood of $x$ in $Gamma(G)$‎. ‎We introduce a new graph determined ...

For the curved n-body problem, we show that set of ordinary central configurations is away from most singular in H^3, and a subset S^3. We also each n!/2 geodesic for n masses has Morse index n-2. Then get direct corollary there are at least (3n-4)(n-1)!/2 given if all these non-degenerate.
