BACKGROUND AND PURPOSE Recent work has shown that fluid-attenuated inversion recovery (FLAIR) imaging with contrast enhancement is highly sensitive for detecting subarachnoid space disease. We hypothesized that contrast-enhanced FLAIR imaging has superior sensitivity to contrast-enhanced T1-weighted MR imaging in detecting leptomeningeal metastases. METHODS Sixty-eight patients referred for s...

A noncovalent complex of the apoprotein (1-104) and cyanogen bromide heme fragment containing residues 1 to 65, (1-65) H, has been prepared from horse heart cytochrome c. Conditions under which the redundant portions of the ferrous complex can be removed by limited trypsin digestion have been devised. The complementing fragments have been isolated from the derived complexes and four apofragment...

PURPOSE OF THE STUDY The purpose of this study was to report our clinical experience, in a pilot study, of the use of the selective cyclooxygenase-2 (COX-2) inhibitor celecoxib, pre-emptively, to control pain in patients after surgical extraction of a mandibular molar tooth. PATIENT AND METHODS This randomised, double-blind, placebo-controlled, prospective clinical trial was conducted over an...

The skin of Helix pomatia was investigated by biochemical methods and electronmicroscope. Biochemical investigations showed that Helix pomatia collagen represents a methionine-lacking collagen resistant to CNBr-cleavage. Electron microscopic studies showed a cross striation pattern of 53--57 nm.

Computer model building with a dynamic energy minimization procedure is used here to study the interaction of a pentapeptide sequence from the lac repressor headpiece (lac 53-57) with different base sequences of DNA. The peptide fragment for this purpose was considered in the classical beta-antiparallel as well as the beta-associated conformation. The model of its interaction with DNA was optim...
