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 asExpand

Integration of lead optimization with crystallography for a membrane-bound ion channel target: discovery of a new class of AMPA receptor positive allosteric modulators.
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 toExpand

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 beenExpand

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 closelyExpand

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 thisExpand
