    Notes: Summary Four human neuroblastoma cell lines exhibited differences in their ability to differentiate into neuron-like cells in response to three different treatments, serum deprivation, or additions of dibutyryl cyclic-AMP or retinoic acid. Expression of N-myc gene product was reduced in neuroblastoma cell line SK-N-DZ differentiated by retinoic acid as compared with untreated cells. On the contrary, expression of c-src gene product, pp60c-src, was considerably enhanced in differentiated SK-N-DZ cells. Tyrosine phosphorylation of several cellular proteins was found to be enhanced in differentiated cells. Alteration in expression of these proto-oncogene products might be important in the differentiation of neuroblastoma cells into neuron-like cells.

    Notes: Abstract The case of a 14-month-old girl presenting with precocious breast development due to adrenal hyperplasia is reported. The endocrine studies revealed a slight elevation of the plasma progesterone, 17α-hydroxyprogesterone, testosterone and oestrone levels, and an increased urinary oestrogen excretion. The findings of the ultrasound examination and the evidence that the oestradiol concentration in the left adrenal vein was higher than in the right adrenal vein confirmed the diagnosis of left adrenal hyperfunction. Surgical exploration revealed unilateral hyperplasia of the adrenal cortex. After adrenalectomy the plasma hormone levels and urinary oestrogen excretion fell to normal, with concomitant regression of breast tissue. The girl shows no signs of recurrence of the disorder in a 2 year follow-up. This adrenal hyperplasia might be a benign adrenal disorder causing precocious breast development.

    Notes: We have developed a new fabrication process of as-grown Y-Ba-Cu-O thin films using a reactive coevaporation method specially with the rf-plasma cooling in the low oxygen pressure of 0.4 mTorr. By this O2 plasma cooling process, the transition temperature Tc is improved from 40 to 81 K for the film with a thickness of 1000 A(ring). The x-ray diffraction analysis shows that the activated oxygen species generated by the rf plasma make Y-Ba-Cu-O films oxidize sufficiently even in the low pressure of oxygen. In addition, we have studied the thickness dependence of Tc for as-grown films with various thicknesses of 60–2000 A(ring).

    Notes: A phase-locked laser diode array with three index waveguides is described. The array has a novel structure which prevents channels from being etched back. As the result, the waveguide elements in the array are very uniform. A stable 180° phase mode oscillation is obtained up to 50-mW output power in the single longitudinal mode and three supermodes are observed simultaneously above 50-mW output power. The near-field patterns and the far-field patterns of these supermodes are in good agreement with the theoretical results.

    Notes: We have carried out at 4-K spin-echo studies (of 55Mn, 63Cu) on sputtered Heusler alloy (Cu2MnAl) films with substrate temperature Ts in the range of 50–300 °C in order to obtain microscopic information on the magnetic structure. For Ts =60 °C a very broad spectrum is obtained, revealing incomplete (disordered) formation of Cu2MnAl. For Ts =158, 167, 170, and 210 °C, well-defined spectra are observed with Mn at 227 MHz and Cu at 241 and 259 MHz, respectively. Signal intensity studies reveal a maximum for Ts =167 °C in general agreement with the magnetization results of Morisako, Matsumoto, and Naoe. The signal frequencies are also in agreement with those obtained for the bulk alloy. For Ts =300 °C, the spectrum is broadened but the signal frequencies of Mn and Cu remain practically the same. This spectrum is also quantitatively different from that observed for the film with Ts=60 °C, where a low-frequency tail is observed. The effect of post-annealing the films is also presented.

    Notes: Mn-Al films have been prepared by dc magnetron sputtering and their crystallographic characteristics, magnetic properties, electrical resistivity, and internal stress have been investigated. The films deposited when substrate temperature Ts was below 100 °C and above 170 °C exhibit a high-temperature ε phase and β-Mn–like structure, respectively. Films of a ferromagnetic τ phase were synthesized with Mn content in the range of 58–62 at. % and Ts of about 150 °C. Existence of CuAu-type superstructure in the τ phase was confirmed by a change of electrical resistivity ρ of deposited films. The films deposited at a Ts of about 150 °C exhibit minimum value of 180 μΩ cm. Lattice constant a and c of the tetragonal τ-phase crystallites in the films were in the range of 3.582–3.592 A(ring) and 3.941–3.968 A(ring), respectively, while those of the bulk alloy were 3.580 and 3.940 A(ring), respectively. The maximum value of saturation magnetization of the films was 120 emu/cc, being as small as about one fourth of that of bulk alloy. This may be caused by elongation of lattice constants and coexistence of nonmagnetic ε phase.

    Notes: The iron nitride thin films have been deposited using a facing targets sputtering (FTS) system and a conventional dc diode magnetron sputtering system, and their crystallographic characteristics and magnetic properties have been investigated. The total gas pressure (PN2+PAr) was set at 2 mTorr. The films deposited by the FTS system without heating the substrate at PN2 below 0.3 mTorr possessed α-Fe-like structure with an increased lattice constant. At PN2 of around 0.5 mTorr, a two-phase mixture of α-Fe and Fe2–3N was formed in the films prepared in the FTS system, while ζ-Fe2N phase was formed in the films prepared by dc magnetron sputtering. The films prepared by FTS at PN2 of 0.1 mTorr possessed α-Fe and γ'-Fe4N structures when a substrate temperature (Ts) was in the range from 80 to 300 °C. The films deposited at Ts of about 150 °C possessed a saturation magnetization (Ms) of about 1700 emu/cm3, which is larger than that of pure iron films and coercivity (Hc) of about 1.5 Oe.

    Notes: Incubation of unfixed skin slices in RPMI 1640 medium for 24—48 h resulted in two types of histological change in psoriatic-involved epidermis. The degenerative change was the major finding in 7 out of 11 psoriatic-involved epidermis, whereas the acantholytic change was observed in the remaining four cases. Neither degenerative nor acantholytic changes were observed in psoriatic-uninvolved epidermis (11 cases) or in normal human epidermis (5 cases). The acantholytic change was observed after only a 12-h incubation and was significantly (but not completely) inhibited by the addition of soybean trypsin inhibitor, which had no effect on the degenerative change of keratinocytes. The addition of hydrocortisone in the incubation medium had no effect on cither degenerative or acantholytic changes of keratinocytes. Our results indicate that a significant population of psoriatic-involved epidermis reveals acantholysis during organ culture in vitro, which might be, at least in part, induced by serine-type protease, the activity of which is known to be increased in the psoriatic-involved epidermis.
