    Notes: Two patients presented with the unusual condition of multiple warty dyskeratomas on the scalp. Biopsies of affected skin stained positive with human keratin monoclonal antibodies HKN-6 and -7, specific for cortex and inner root sheath of normal human hair, respectively. Multiple warty dyskeratomas are a rare occurrence and their actiopathogenesis remains elusive. Positive immunohistochemical staining of a lesion with antikeratin antibodies HKN-6 and -7, specific for human hair keratin, suggests a follicular origin for warty dyskeratoma.

    Notes: We describe a 23-year-old Japanese man with systemic lupus erythematosus (SLE) who developed massive cutaneous mucinosis. He was diagnosed with SLE when he was 11 years old. Prednisolone therapy (30 mg/day) was initiated and reduced to 10 mg/day 3 months later: the SLE had been well-controlled with this dose of prednisolone for 12 years. However, infiltrated erythematous plaques developed on the middle-lateral area of his back at 17 years old and progressed to erythematous and elastic soft tumorous masses over 20 cm in diameter at 23 years old. Biopsies of the lesions on the nape revealed massive mucin deposition. Topical injection with hyaluronidase decreased the lesion. This cutaneous mucinosis can be distinguished clinically and histopathologically from papular and nodular mucinosis associated with SLE. The present case might be an unusual clinical variant of cutaneous mucinosis associated with SLE.

    Notes: Two types of spiral growth, single and double spirals, of C60 epitaxial films on a KBr(001) substrate were observed by atomic force microscopy (AFM). These single and double spirals were found on films grown at different rates. All spiral islands show the threefold symmetry of the face-centered-cubic (fcc) structure. In the case of single spirals, many fringes were observed in three equivalent [11¯0] directions on the fcc (111) surface. From the AFM images, we concluded that the growth process of these spirals can be explained by the classical crystal growth theory of Burton, Cabrera, and Frank and that screw dislocations form without any direct influence of the substrate. © 1997 American Institute of Physics.

    Notes: We report the clinical, histological and ultrastructural features of juvenile colloid milium affecting a brother and sister. In this rare condition, translucent papules develop on sun-exposed areas of skin, with onset in childhood. Histologically and ultrastructurally, the papules consist of amyloid-like material derived from epidermal keratonocytes. A review of the literature suggests a possible genetic abnormality that leads to sun-induced degeneration of keratinocytes.

    Notes: We report a patient with herpetiform pemphigus(HP)who showed reactivity only with pemphigus vulgaris(PV)antigen but not with pemphigus foliaceus(PF)antigen. Direct and indirect immuno- fluorescence revealed keratinocyte cell surface staining in the lower layers of the epidermis, where desmoglein 3 (Dsg3) is expressed. Immunoblot analysis, using ethylenediamine tetra-acetic acid- separated human epidermal extracts, revealed that the patient's serum recognized only a 130-kDa polypeptide which co-migrated with Dsg3. By antigen-specific immunoadsorption studies, using desmoglein 1 (Dsg1) and Dsg3 recombinant protein produced by baculovirus expression system, immunoreactivity of the patient's serum was completely adsorbed by Dsg3 alone, but not by Dsg1. These results indicate that this HP patient produced only anti-Dsg3 autoantibodies and no other autoantibodies against components of the keratinocyte cell surface. HP could be a variant of PV.in addition to PF, with unique clinical and histological features.

    Notes: Abstract Utilizing the fact that the equilibrium potential of oxygen evolution is lower than that of chlorine evolution, oxygen evolution in seawater electrolysis was enhanced by decreasing the polarization potential under galvanostatic conditions through increasing the effective surface area of manganese oxide electrodes. Electrodes were prepared by a thermal decomposition method. IrO2-coated titanium (IrO2/Ti electrode) was used as the substrate on which manganese oxide was coated (MnOX/IrO2/Ti electrode). Subsequently, oxide mixtures of manganese and zinc were coated (MnOX–ZnO/MnOX/IrO2/Ti electrode). The effective surface area of the MnOX–ZnO/MnOX/IrO2/Ti electrodes was increased by selective dissolution of zinc (leaching) into hot 6M KOH. The oxygen evolution efficiency of the MnOX/IrO2/Ti electrode was 68–70%. Leaching of zinc from the MnOX–ZnO/MnOX/IrO2/Ti electrodes with 25mol% or less zinc led to a significant increase in the oxygen evolution efficiency. The maximum efficiency attained was 86% after leaching of zinc from the MnOX–25mol%ZnO/MnOX/IrO2/Ti electrode. However, large amounts of zinc addition, such as 40mol% or more are detrimental because of a decrease in the oxygen evolution efficiency. This is due to the formation of a double oxide, ZnMnO3, which is hardly dissolved in hot 6M KOH.

    Notes: Abstract Powder catalysts were prepared by immersion of amorphous Ni-40Zr and Ni-40Ti alloys containing a few at % of platinum group elements in HF solution. This treatment led to preferential dissolution of the valve metal and nickel with a consequent formation of microcrystalline alloy powders consisting of concentrated platinum group elements and some nickel and valve metal. Porous gas-diffusion electrodes prepared by using these alloy catalyst powders were employed for electrochemical reduction of oxygen and oxidation of hydrogen in 1 M H2SO4 at 25°C. The activity of the electrodes prepared from the amorphous alloys containing Pt−Ru, Pt−Rh, Pt and Pd for oxygen reduction was considerably higher than that of the platinum black electrode. Oxidation of hydrogen occurred readily close to the equilibrium potential. Amorphous alloy electrodes containing Pt−Ru, Pt−Rh and Pt were more active than the platinum black electrode for the hydrogen oxidation.

    Description / Table of Contents: Zusammenfassung Der Polymorphismus des FXIIIB wurde bei 555 unverwandten Japanern mit Hilfe der isoelektrischen Fokussierung und anschließendem Immunoblotting untersucht. Fünf allgemein vorkommende Phänotypen und die seltene Variante FXIIIB 15-3 wurden beobachtet. Die Allel-Frequenzen waren FXIIIB = 0,3063, FXIIIB2 = 0,0162, FXIIIB3 = 0,6766 und FXIIIB15 = 0,0009. Die Bestimmung der Phänotypen war auch an Blutspuren mit folgenden Lagerungsbedingungen möglich: Bei 37°C über einen Zeitraum bis zu 4 Monate, bei Raumtemperatur und bei 4°C länger als 6 Monate. Das FXIIIB-System kann einen neuen, aussagekräftigen genetischen Marker für gerichtsmedizinische Blutspurenuntersuchungen darstellen.
    Notes: Summary The polymorphism of FXIIIB was investigated in 555 unrelated Japanese individuals using isoelectric focusing and immunoblotting. Five common phenotypes and a rare variant type FXIIIB 15-3 were observed. The allele frequencies were FXIIIB*1 = 0.3063, FXIIIB*2 = 0.0162, FXIIIB*3 = 0.6766 and FXIIIB*15 = 0.0009. Phenotyping was also possible from bloodstains stored at 37°C for up to 4 months and from bloodstains stored at room temperature and at 4°C for over 6 months. The FXIIIB system can provide a new powerful genetic marker for the medicolegal grouping of bloodstains.
