Crystal structure of the IMP-1 metallo beta-lactamase from Pseudomonas aeruginosa and its complex with a mercaptocarboxylate inhibitor: binding determinants of a potent, broad-spectrum inhibitor.
Metallo beta-lactamase enzymes confer antibiotic resistance to bacteria by catalyzing the hydrolysis of beta-lactam antibiotics. This relatively new form of resistance is spreading unchallenged as… Expand

A novel series of AMPAR positive modulators is described that were identified by high throughput screening. The molecules of the series have been optimized from a high quality starting point hit to… Expand
Beyond the "device as portal": meeting the requirements of wireless and mobile devices in the legion grid computing system
This paper describes the unique capabilities of the Legion Grid computing infrastructure that will directly support these next-generation, powerful devices as first-class entities.Grid computing is an emerging paradigm in which resources in multiple organizations are combined into a single, seamless computing environment.

Piety and Nationalism: Lay Voluntary Associations and the Creation of an Irish-Catholic Community in Toronto, 1850-1895
While the role of the laity in the nationalist awakening is commonly recognized, their part in the movement for religious renewal is usually minimized. Initiative on the part of the laity has been… Expand
6-(SUBSTITUTED METHYLENE)PENEMS, POTENT BROAD SPECTRUM INHIBITORS OF BACTERIAL β-LACTAMASE
Sodium (5RS)-Z-6-(heterocyclylmethylene)penem-3-carboxylates (2) are a series of extremely potent inhibitors of bacterial β-lactamases. A variety of 5-membered heteroaromatic derivatives have been… Expand
Structural imperfections and singlet exciton traps in crystalline anthracene
Abstract Changes in spectral frequencies and intensities recorded at low temperatures (4 to 40 K), as well as measurements of prompt-fluorescence lifetimes, of annealed and deformed high-purity… Expand

The relationship between crystallographic structure and luminescence in single crystals of acridine
Abstract Crystalline luminescence spectra of five modifications of acridine are reported. The spectrum of one form (acridine V) is characteristic of emission from monomeric species and closely… Expand
Acridine: an investigation of its molecular and crystalline photophysical behaviour
The absorption spectrum of acridine in various solvents together with the fluorescence spectra and lifetimes in a rigid matrix confirms the presence of a weak, intrinsic π–π* emission in this… Expand
