    Notes: Abstract This study explored responses of chronic low back pain patients to treatment for different types of patients (“dysfunctional,” “interpersonally distressed,” and “minimizer/adaptive coper”), as classified using the Multidimensional Pain Inventory (MPI). In addition, changes in MPI scores during treatment were examined separately for each patient type. Finally, this study explored the relationships between changes in MPI scores and physical improvement. Between-group differences in improvement were significant, with “dysfunctional” patients showing the most improvement on several scales. MPI scales that best predicted physical improvement differed according to patient type. Implications for treatment of low back pain patients are suggested, based upon differential reactions to treatment and different predictors of physical improvement for each patient group.

    Notes: The sequence-specific recognition of double-helical DNA by oligonucleotide-directed triple helix formation is limited primarily to purine tracts. To identify potential lead compounds which are able to extend the sequence repertoire of triple helical complexes, we designed two carbocyclic nucleosides with nucleobases attached via amide bonds. N5-[(1R, 2S, 3R, 4R)-3-hydroxy-4-(hydroxymethyl)-2-methoxycyclopentyl]-2-{[(1H-pyrrol-2-yl)carbonyl]-amino}thiazole-5-carboxamide (L1) and 2-benzamido-N5-[(1R, 2S, 3R, 4R)-3-hydroxy-4-(hydroxymethyl)-2-methoxycyclopentyl]thiazole-5-carboxamide (L2) were synthesized and incorporated into pyrimidine oligonucleotides. The 2-(trimethylsilyl)ethoxymethyl (SEM) protecting group for the 1H-pyrrole NH was found to be compatible with DNA solid-phase synthesis of pyrimidine Oligonucleotides. By quantitative DNase I footprinting analysis, both nonnatural nucleosides L1 and L2 showed preferential binding of pyrimidine over purine bases: L1/2·(C·G) ≈ L1/2·(T · A) 〉 L1/2·(G·C) ≈ L1/2·(A · T). Comparison with the previously reported nonnatural nucleosides with extended aromatic nucleobases 1-(2-deoxy-β-D-ribofuranosyl)-4-(3-benzamidophenyl)-imidazole (D3) and N4-[6-(benzamido)pyridin-2-yl]-2′-deoxycytidine (bzM) suggests that the observed binding selectivity C · G ≈ T · A 〉 G · C ≈ A · T for the nucleoside analogs L1, L2, D3, and bzM is derived from sequence-specific intercalation with preferential stacking of their nucleobases over pyrimidine · purine Watson-Crick base pairs.

    Description / Table of Contents: Metalloporphyrine in polymeren Matrizen. Mizellen und Vesikeln, VI. - Hydrophobe und hydrophile Derivate des 3,8-Diformyldeuteroporphyrin-dimethylesters und ihre Wechselwirkung mit Vesikeln3,8-Diformyldeuteroporphyrin-dimethylester (1a) wurde durch Ozonisierung des diprotonierten Dikations von Protoporphyrin-dimethylester 1b erhalten. Mehrere Derivate wurden dargestellt, die entweder hydrophobe Eigenschaften aufweisen oder hydrophile Substituenten in der “nördlichen Hemisphäre” des Porphyrinliganden oder an beiden Seiten tragen. Die Porphyrine wurden in wäßrigen Medien gelöst, die Vesikel mit elektroneutralen, -negativen oder -positiven Oberflächenladungen enthielten. Der Aufenthaltsort der gelösten Porphyrine wurde durch den spektroskopischen Nachweis von Reaktionen der zentralen Porphyrin-Stickstoffatome oder von peripheren Substituenten mit wasserlöslichen Säuren oder Metall-Ionen bestimmt.
    Notes: 3,8-Diformyldeuteroporphyrin dimethyl ester (1a) was obtained by ozonization of the diprotonated dication of protoporphyrin dimethyl ester 1b. Several derivatives have been prepared, which are either hydrophobic, or bear hydrophilic substituents in the „northern hemisphere“ of the porphyrin ligand or on both sides. The porphyrins have then been dissolved in aqueous media containing vesicles with electroneutral, -negative, or -positive surface charges. The localization of the dissolved porphyrin chromophore was determined spectroscopically following reactions of the central porphyrin nitrogen atoms or of peripheral substituents with water-soluble acids or metal ions.
