The dithio-carbamate anions in the title compound, [Ni(C(7)H(14)NS(2))(2)], chelate to the Ni(II) atom, which is four-coordinate in a square-planar geometry. The Ni(II) atom lies on a center of inversion.

The heterotopic urinary bladder with a communicating reservoir is a potentially useful model for bladder carcinogenesis studies. As a test of whether such bladders will develop transitional cell carcinomas after chronic carcinogenic stimuli, two carcinogens, N-methyl-N-nitrosourea and N-butyl-N-(3-carboxypropyl)nitrosamine, were instilled repeatedly into the reservoir connected with the heterot...

Incremental reactivity estimates for many high molecular weight organic compounds used in consumer products are viewed as uncertain because of limited data on their reaction mechanisms and products. This study performs a systematic uncertainty analysis of the calculated incremental reactivities of two such compounds: n-butyl acetate and 2-butoxy ethanol. 2-butoxy ethanol is a relatively well-st...

Apolygus lucorum (Hemiptera: Miridae) is an important insect pest of cotton and fruit trees in China. The adults prefer host plants at the flowering stage, and their populations track flowering plants both spatially and temporally. In this study, we examine whether flower preference of its adults is mediated by plant volatiles, and which volatile compositions play an important role in attractin...

We report the behaviour of thermoresponsive block copolymers of n-butyl acrylate and N-alkyl acrylamides in [C2mim][NTf2]. Poly(N-isopropylacrylamide) exhibits an upper critical solution temperature in [C2mim][NTf2] whereas poly(n-butyl acrylate) has a lower critical solution temperature. Consequently, these polymers exhibit double thermo-responsiveness correlated with the macromolecular struct...

OBJECTIVE This research was aimed to investigate the correct dose of nitrite that would act as a protection against the ischemic effects induced by acute myocardial infarction (AMI). METHODS Mice were randomly divided into a sham-operation group (sham), an AMI operation group (AMI), and a nitrite pretreatment+AMI operation group (N+AMI). Seven days before the AMI operation, mice in the N+AMI ...

In the title compound {systematic name: cis-bis-[4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidato-κ(2)N,N']bis-(butyl-amine-κN)copper(II) penta-hydrate}, [Cu(C(10)H(9)N(4)O(2)S)(2)(C(4)H(11)N)(2)]·5H(2)O or [Cu(sdz)(2)(ba)(2)]·5H(2)O [ba is butyl-amine and sdz = sulfadiazine(1-)], the copper(II) cation is six-coordinated by four N atoms of two sulfadiazine ligands and two N atoms of butyl-amine ...

The title compound, C18H30N2O5S, was synthesized by the reaction of tert-butyl 2-(iso-butyl-amino)-ethyl-carbamate with p-meth-oxy-phenyl-sulfonyl chloride. In the mol-ecule, two intra-molecular C-H⋯O hydrogen bonds are observed. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds involving the imino group N atom and the ester group O atom into chains running parallel to the b axis. T...
