Objective(s): Cholinergic neurons are important neurons in the Pedunculopontine tegmental nucleus (PPT). In this study, nicotinic receptor of the PPT in central cardiovascular regulation in the anesthetized rat was evaluated. Materials and Methods: Saline, acetylcholine (Ach; doses: 90 and 150 nmol), hexamethonium (Hexa; doses: 100 and 300 nmol) and higher doses of Hexa (300 nmol) + Ach (150 nm...

The title compound, C(15)H(17)N(5)O(2), was synthesized as part of a series of benzoxadiazole analogs which were examined for fluorescent properties by Cu-catalysed azide-alkyne cyclo-addition (CuAAC) of a 4-azido-methyl-benzoxadiazole substrate. The structure shows a nearly coplanar orientation of the hexa-none keto group and the 1,2,3-triazole ring [dihedral angle = 4.3 (3)°], while the benzo...

The terminase enzyme from bacteriophage lambda is composed of two viral proteins (gpA, 73.2 kDa; gpNu1, 20.4 kDa) and is responsible for packaging viral DNA into the confines of an empty procapsid. We are interested in the genetic, biochemical, and biophysical properties of DNA packaging in phage lambda and, in particular, the nucleoprotein complexes involved in these processes. These studies r...

In the title compound, {[Cu(2)(C(4)H(2)O(4))(2)(H(2)O)(2)]·3H(2)O}(n), Cu(II) ions with square-pyramidal coordination are bridged by exo-tri-dentate maleate dianions into [Cu(2)(maleate)(2)(H(2)O)(2)](n) layers coincident with the bc crystal plane. The inter-lamellar regions contain hydrogen-bonded cyclic water hexa-mers which facilitate layer stacking into a pseudo-three-dimensional crystal st...

We describe the synthesis of a new tetratopic phenoxyl radical ligand based on the previously reported ditopic “baqp” radical. The tetratopic ligand is prepared in five steps from 4-tert-butylphenol. Coordination of the ligand with Cu(OAc)2 produced a tetranuclear complex with an S = 2 ground state featuring a coordinated hexa-anion radical with very strong intramolecular antiferromagnetic exch...

Data structures representing directed graphs with edges labeled by symbols from a finite alphabet are used to implement packet processing algorithms used in a variety of network applications. In this paper we present a novel approach to represent such data structures, which significantly reduces the amount of memory required. This approach called History-based Encoding, eXecution and Addressing...

The lysosomal enzyme, beta-hexosaminidase, exists as two major isoforms; HexA and HexB. HexA is an alpha beta-subunit heterodimer and HexB a beta-subunit homodimer. Both isoforms can remove nonreducing beta-N-acetyl-D-glucosamine residues, whereas HexA hydrolyzes charged substrates as G(M2) gangliosides as well. beta-Hexosaminidase is present in both human and rabbit tear fluid and is secreted ...

Phenotypic heterogeneity in microbial communities enables genetically identical organisms to behave differently even under the same environmental conditions. Photorhabdus luminescens, a bioluminescent Gram-negative bacterium, contains a complex life cycle, which involves a symbiotic interaction with nematodes as well as a pathogenic association with insect larvae. P. luminescens exists in two d...

Single crystals of the title compound bis[bis-(1-ethyl-3-methyl-imidazol-2-yl-idene)silver(I)] 1,5,5,7,11,11-hexa-chloro-2,8-di-oxa-4,6,10,12,13,14-hexa-aza-1λ(5),3,5λ(5),7λ(5),9,11λ(5)-hexa-phospha-tricyclo-[7.3.1.1(3,7)]tetra-deca-1(13),4,7(14),10-tetra-ene-6,12-diide 3,9-dioxide, [Ag(C(6)H(10)N(2))(2)](Cl(6)N(6)O(4)P(6))(0.5), were isolated from the reaction of the silver N-heteocyclic carbe...
