    Notizen: Patients were recruited from 1 December 1994 until 31 August 1995. Those presenting with tinea cruris/corporis received 200 mg of itraconazole every day for 7 days, whereas patients presenting with tinea pedis/manus were treated with 200 mg twice a day for 7 days. Those eligible were men and women at least 18 years of age, with a clinically diagnosed dermatophytosis, confirmed by KOH examination and culture. Pregnant or nursing patients and those who did not use adequate birth control methods were excluded. Patients with a known history of chronic liver disease or other concomitant serious disease were also excluded. Patients who had received any oral antifungal or corticosteroid therapy within 30 days before enrollment or any topical antifungal or corticosteroid treatment within a week before enrollment were not eligible.Clinical and mycologic (KOH and culture) evaluation was carried out at baseline, at completion of therapy (day 7) and at the end of follow-up (day 28 for tinea cruris/corporis and day 35 for tinea pedis/manus). The investigator evaluated the following clinical symptoms at each visit: desquamation, erythema, infiltration, pruritus, exudation, maceration, vesiculation, and pustules. Clinical results were rated as: healed, markedly improved, considerable residual lesions, not changed, or worse. The categories healed and markedly improved were considered as responders.All mycology was performed centrally at the Department of Microbiology, University of Malaya.

    Notizen: Abstract. In this paper we give a fully dynamic approximation scheme for maintaining all-pairs shortest paths in planar networks. Given an error parameter $\epsilon$ such that $0〈\epsilon$ , our algorithm maintains approximate all-pairs shortest paths in an undirected planar graph G with nonnegative edge lengths. The approximate paths are guaranteed to be accurate to within a 1+ $\epsilon$ factor. The time bounds for both query and update for our algorithm is O( \epsilon -1 n 2/3 log 2 n log D) , where n is the number of nodes in G and D is the sum of its edge lengths. The time bound for the queries is worst case, while that for the additions is amortized. Our approximation algorithm is based upon a novel technique for approximately representing all-pairs shortest paths among a selected subset of the nodes by a sparse substitute graph.

    Notizen: Abstract Structural and x-ray photoelectron spectroscopy (XPS) studies of the Tl1−xPbxSr1+xLa1−xCuO5−y (0.0≤x≤0.5) system have been carried out. The unit cell parameters increase with x. Irrespective of x the Tc is retained in this series and the optimum hole concentration (nh) is maintained for x≤ 0.5. An increase in Tl 4f and O ls binding energy with x suggests a reduction in their oxidation state. Origin of holes is discussed in terms of charge transfer between Tl, Pb and CuO2 layers.

    Notizen: Abstract AMI semiempirical molecular orbital calculations were carried out on lapachol and several derivatives of 1,4-naphthoquinone in order to investigate possible relationships between electronic structural parameters and activity against carcinosarcoma Walker 256 (W256). It was found that, among the calculated electronic indices, that the HOMO (highest occupied molecular orbital) coefficients for carbon atoms of the side-chain double bond have a significant influence in the activity, while the LUMO (lowest unoccupied molecular orbitals) apparently have no importance. Exploratory data analysis through hierarchical cluster (HCA) and principal component analysis (PCA) showed a clear separation of the active compounds from the inactive ones. The activity against W256 probably involves a mechanism wherein the quinone acts as a reducing agent through the participation of the π-electrons of the side-chain double bond. A classification study with respect to structure-activity using KNN (K-nearest neighbors) and SIMCA (soft independent modeling of class analogy), two established chemometric methods of pattern recognition, have been used to predict activity for a series of lapachol derivatives.
