Abstract

Lumbar punctures (LP) are complex, precise procedures done to obtain cerebro-spinal fluid from a patient for diagnostic purposes. Incorrect techniques resulting from inadequate training or supervision can result in sub-optimal outcomes. As tactile feedback is crucial for a successful lumbar puncture, this procedure serves as an ideal candidate for the development of a haptic training simulator. The intent of this project is to engineer a force feedback LP simulator that provides a safe method of training students (medical students, residents, or trained physicians) for an actual LP procedure on a patient.

Self-assembled helices from 2,2'-biimidazoles.

2,2'-Biimidazoles were synthesized by palladium(0)-catalyzed coupling of 2-iodoimidazoles bearing an alkyl and an ester group at the 4- and 5-positions, respectively. The products were found to be fluorescent and moderately soluble in organic solvents. Three biimidazoles were subjected to single crystal X-ray diffraction analysis. In all three instances, adjacent molecules were found to be bound together in the solid state by pairs of N-H...N hydrogen bonds, forming twisted ribbon-like columns which resemble double helices. The amount of helical twist observed between neighboring biimidazole subunits in these helices varies with the identity of the alkyl and ester groups; in two cases it is approximately 60 degrees, whereas in the third it is about 90 degrees. Mass spectra of six different biimidazoles display ions with masses corresponding to dimers; this indicates that these compounds retain some affinity for each other in the gas phase. The three most soluble biimidazoles also show mass spectrometric peaks ascribable to trimers and tetramers. The solution-phase aggregation tendencies of these latter three compounds were studied by vapor pressure osmometry. In each case, the apparent molecular weight in 1,2-dichloroethane solution is higher than would be expected for free monomers.

PDBsum: summaries and analyses of PDB structures.

PDBsum is a web-based database providing a largely pictorial summary of the key information on each macromolecular structure deposited at the Protein Data Bank (PDB). It includes images of the structure, annotated plots of each protein chain's secondary structure, detailed structural analyses generated by the PROMOTIF program, summary PROCHECK results and schematic diagrams of protein-ligand and protein-DNA interactions. RasMol scripts highlight key aspects of the structure, such as the protein's domains, PROSITE patterns and protein-ligand interactions, for interactive viewing in 3D. Numerous links take the user to related sites. PDBsum is updated whenever any new structures are released by the PDB and is freely accessible via http://www.biochem.ucl.ac.uk/bsm/pdbsum.
