The effect of side-chain shortening of N/OFQ(1-13)NH(2) at position 9 ([Orn(9)]N/OFQ(1-13)NH(2), [Dab(9)]N/OFQ(1-13)NH(2), [Dap(9)]N/OFQ(1-13)NH(2)) was studied regarding potential toxicity and antioxidant capacity. Staurosporine- and H2O2-induced damage of SH-SY5Y neuroblastoma cells was not changed in the presence of N/OFQ(1-13)NH(2) and [Orn(9)]N/OFQ(1-13)NH(2), but was strongly enhanced in ...

Open-cage derivative C(60)(O)(4)(OH)(2)(NC(6)H(4)(t)Bu)(2) reacts with ICl to form a Baeyer-Villiger type product, which yields an intense green product upon treatment with HI.

Two papers examining mental incapacity among psychiatric in-patients are presented in the Journal this month – one investigation focuses on assessment reliability (Cairns et al, pp. 372–378) and one on the prevalence and predictors of incapacity (Cairns et al, pp. 379–385). The authors find that the MacArthur Competence Assessment Tool for Treatment (MacCAT– T) can be used reliably to assess ca...

Let G be a graph of order n with an edge-coloring c, and let δc(G) denote the minimum color-degree G. A subgraph F is called rainbow if all edges have pairwise distinct colors. There been lot results on cycles edge-colored graphs. In this paper, we show that (i) δc(G)>2n−13, then every vertex contained in triangle; (ii) δc(G)>2n−13 n≥13, C4; (iii) complete, n≥7k−17 δc(G)>n−12+k, contains cycle ...

The reactivity of quinoneimines towards ketene and diphenylketene was examined. N-Phenylbenzoquinoneirnines (I), (2) and also N-phenylnaphthoquinoneimine react with ketene to give the spiro-adducts (5), (7) and (1 1) respectively. These adducts were stable even after prolonged heating in high boiling solvent. Reaction of the above imines with diphenylketene also afforded 13- lactam spiro-a...
