    Notes: Two cases of congenital onychoheterotopia (ectopic nail) are described. In the first case electron microscopy showed spherical keratohyalin granules, and cytoplasmic desmosomes were seen in the keratinocytes of the nail matrix. The ectopic nail differed from the normal nail in the widening of the angle between the nail matrix and proximal nail fold, and in its radial growth to the skin surface. In the second case, clippings of the ectopic nail were taken and their hardness proved to be very similar to that of normal nails.

    Tick bite: two cases studied by scanning electron microscopy (1984)

    Notes: The attachment of ticks to human skin has been studied by scanning electron microscopy. Intact specimens of Ixodes ovatus and Ixodes persulcatus were examined, and we also studied the skin of two patients who had been bitten by these two species. In the first case, the remains of the tick were visible and a homogeneous cement-like substance was observed on the dorsal hypostome and in the dermis, suggesting that the tick attaches itself to the host skin by a secretion. In the second case, the apices of some denticles of the hypostome were chipped. Two months later, the skin which the tick had attacked was biopsied and yellowish-brown particles, probably derived from the denticles, were seen in foreign body giant cells in the dermis.

    Studies on components 1' (modified monomer) and 2 (dimer) formed during heat-treatment of bovine serum albumin (1984)

    Notes: Abstract When the solution of bovine serum albumin at pH 9 is incubated at 65 °C, new components 1' (modified monomer), 2 (dimer) and 3 (probably trimer) are formed. The isoelectric focusing indicated that the isoelectric points of components 1', 2 and 3 were pH 5.9. The hydrogen ion titration curve for the native albumin had well known abnormal steepness at pH near 4, but that for component 1' had no abnormal steepness. The titration curve for component 1' located right side of that for the native albumin. Circular dichroism measurements indicated that some unfolding occurred, when the native albumin was changed to component 1'. The contents ofα-helix were 74 and 52 % for the native albumin and for component 1', respectively. The contents of β-structure were 19 and 23 % for the native albumin and for component 1', respectively. The wavelength of maximum intensity of tryptophan fluorescence shifted to lower wavelength, when the native albumin was changed to component 1'. This suggests that tryptophan residue(s) is transferred to a more hydrophobic environment. The hydrogen ion titration curves, circular dichroism and fluorescence measurements, all supported the possibility that the component 2 is formed by the dimerization of component 1'. Further, it has been found that component 2' (dimer impurity in commercial bovine serum albumin preparations) is formed by the direct dimerization of native bovine serum albumin without conformational change.

    Notes: Summary The photoreceptor cells in the pineal organ of the Japanese common newt are similar to typical vertebrate photoreceptors. It is supposed that the cells are responsible for the entrainment of locomotor rhythms as a consequence of their response to light.

    Description / Table of Contents: Sommario Si considera il problema matriciale di Riemann-Hilbert che si presenta nel risolvere il modello BGK per problemi dipendenti dal tempo in un semispazio. Facendo uso di un metodo originariamente introdotto da uno degli autori per problemi stazionari si indica un procedimento per ottenere una soluzione per via analitica.
    Notes: Abstract The matrix Riemann-Hilbert problem arising in the time-dependent BGK model for half space problems is analyzed. The method used is similar to the one originally introduced by one of the authors for steady problems. A general procedure is given which leads to closed form solutions.

    Description / Table of Contents: Sommario Seguendo il procedimento indicate nella prima parte, si presenta una soluzione canonica del problema matriciale di Riemann-Hilbert per la propagazione del suono in un gas che occupa un semispazio.

    Notes: Abstract A nationwide neonatal sreening program for phenylketonuria (PKU), maple syrup urine disease (MSUD), homocystinuria, histidinemia and galactosemia was started in Japan in 1977. The total number of infants screened had reached 6,311,754 by March, 1982. A follow-up study revealed the incidence of the disease in Japan: 1/108,823 for PKU; 1/450,840 for hyperphenylalaninemia (HPA); 1/1,577,939 for biopterin deficiency; 1/525,980 for MSUD; 1/1,051,959 for homocystinuria; 1/8,371 for histidinemia, and 1/788,969 for galactosemia type 1. The incidences of PKU, HPA, homocystinuria, and galactosemia (type 1) were found to be markedly low in Japan as compared with those in Caucasian countries. There was no great difference in the incidence of MSUD between both. On the other hand, the incidence of histidinemia was higher in Japan. It was found that most of the patients with PKU, HPA, MSUD, homocystinuria, or galactosemia are developing normally due to the early initiation of dietary treatment. These results clearly indicate that the neonatal mass screening program plays a great role in preventing the occurrence of handicapped children.
