    Notes: Abstract Between November 1982 and August 1984 diving observations of two intertidal limpets' defensive behaviours in response to two predatory species were made near the Seto Marine Biological Laboratory of Kyoto University, in Wakayama Prefecture, Japan, for over 800 h. The focus of the observations was a simple isolated rock, 0.9 m2 in area with an inclination of 75°. The pulmonate homing limpet Siphonaria sirius responded by fleeing from its home in response to the whelk Thais clavigera and by calmping tightly to its home scar in response to the starfish Coscinasterias acutispina. Both behaviours were successful for avoiding predation. After a whelk moved far away, limpets returned to their homes. The patellid limpet Cellana toreuma showed mantle folding behaviour or fled for an average distance of 8 cm vertically upwards in response to the whelk and for an average distance of 21 cm vertically upwards in response to the starfish. The amount of time predators spent foraging increased in the low intertidal zone relative to the mid and high zones, and most predator attacks were observed during the limpets' resting periods (submersion in late afternoon or nighttime). The upward directional flight displayed by C. toreuma was related to the upward orientation of the limpets' heads when they are in a resting position. Half of the limpets observed fleeing downward away from a starfish, a movement elicited by a downward attack, received a second attack. These limpets were preyed upon at the second encounter 67% of the time. The upward fleeing behaviour of C. toreuma resulted in the shifting of its resting site higher up the study site where fewer attacks occurred and where the mortality rate was at its lowest. It is suggested that the homing behaviour of S. sirius and the upward fleeing behaviour of C. toreuma are mechanisms by means of which interspecific competition between limpets is reduced and coexistence on a small rock surface is maintained.

    The effect of Ag doping on superconducting properties of the Bi-Pb-Sr-Ca-Cu-O tape fabricated by an Ag sheath (1992)

    Notes: The powder-in-tube method using an Ag sheath is applied to achieve high current capacity in the tapes of Bi-Pb-Sr-Ca-Cu-O (BPSCCO) with the high-Tc phase (Tc=110 K), by a combination process of cold working and sintering. Two kinds of the BPSCCO powder with and without Ag doping are used as the materials for tape fabrication. The morphology, structure, and critical current density Jc are investigated on the tapes by x-ray diffraction, differential thermal analysis, scanning electron microscope, magnetic susceptibility, and I-V curves. The optimum sintering conditions to obtain a maximum in the value of Jc at 77 K and 0 T are presented in the Ag-doped tapes and the nondoped ones. An improvement in the Jc vs B properties up to 1 T at 77 K is presented in the BPSCCO tape by Ag doping. The Ag doping causes neither change in the value of Tc (=110 K) nor decomposition of the high-Tc phase.

    Notes: We report a 3-month-old male infant with marked folding of the skin, who manifested mental retardation and delayed growth at the age of 31 months. Histological examination of the folded skin disclosed smooth muscle hamartomatous changes. To our knowledge, this represents the third reported case of folded skin with an underlying smooth muscle hamartoma.

    Notes: Abstract To investigate the development of the blood vessels forming the secondary ossification center in the femoral heads of growing rats, we observed the specimens of the proximal femurs having vascular casts using both an optical and a scanning electron microscopy (SEM). Histologically, the vascular invasion occurred from the lateral part of the cartilaginous epiphysis, prior to the appearance of the ossification center. The vascular casts were prominent within the cellular spaces consisting of a few hypertrophic chondrocytes. The SEM study suggested that the vascular buds had peculiar structures and invaded the cartilaginous epithysis by breaking through the cellular spaces. The blood vessels budded out from the arch of the lateral epiphyseal vessels toward the femoral heads. The sizes of the large-caliber vascular buds of about 50 μm in diameter were similar to those of the cellular spaces, and they penetrated into the epiphysis by repeated merging and branching. Many deep impressions were noted on the surface of the vascular buds, and the tips showed the peculiar shape similar to a suction cup.

    Notes: Summary We report a patient with spontaneous recovery and recurrence of a jugular foramen syndrome secondary to an accessory nerve neuroma. He showed sudden onset of unilateral palsy of the ninth, tenth and eleventh cranial nerves in 1982. He recovered almost fully and in 1990 the palsies recurred. MRI revealed a small mass in the right jugular foramen. The tumour was resected via suboccipital craniectomy, and diagnosed as a neuroma of the eleventh cranial nerve.

    Curative local control of malignant tumors in the acetabulum by intraoperative radiotherapy (1994)

    Notes: Abstract As treatment for malignant tumors in the acetabular region of the pelvis, radiotherapy, mainly in the form of intraoperative radiotherapy (IORT), was carried out in four patients. One had a malignant fibrous histiocytoma of bone and three had metastatic tumors from the stomach and lung. Over follow-up period, ranging from 3 to 46 months, satisfactory limb function was preserved in three patients; the fourth suffered from femoral nerve palsy as a complication of IORT. Cessation of growth was observed radiologically in all the tumors, and curative local control was proven histologically in two patients at autopsy.

    Association of the Sendai virus C protein with nucleocapsids (1990)

    Details

    Topics: Medicine
    Notes: Summary The subcellular localization of the nonstructural protein C of Sendai virus was investigated by means of indirect immunofluorescence microscopy of Sendai virus-infected cells, using an antiserum specific for C protein. In infected cells, C protein was detected exclusively in the cytoplasm as granular fluorescence, which coincided very well with the distribution of nucleocapsid protein NP and phosphoprotein P, which were also detected with specific antisera. This suggested that these proteins are present together in inclusions, probably forming nucleocapsids. In contrast, when the NP and C proteins were individually expressed in COS cells by transfection with expression plasmids containing cDNA for these proteins, their distribution patterns in the cytoplasm were found to be quite different from each other. Protein-blot analyses of purified virions revealed the presence of a significant amount of the C protein in virions, which indicated that C protein is integrated into virions. Under conditions in which most of the envelope-associated proteins, such as HN, F, and M, were removed from the virions by a detergent, the C protein remained tightly associated with the nucleocapsids — about 40 molecules per nucleocapsid.

    Description / Table of Contents: Résumé Nous avons étudié sur le plan clinique et anatomo-pathologique, chez 20 malades atteints de tumeurs osseuses de haut degré de malignité, la valeur de la radiothérapie à la dose de 30 Gy en complément de la chimiothérapie pré-opératoire. L'histologie des pièces réséquées chirurgicalement a montré un effet tumoricide considérable et l'encapsulement de la partie extra-osseuse de la tumeur. La radiothérapie n'a pas déterminé d'effets secondaires fâcheux. Elle paraît donc indiquée pour la conservation des membres en cas de tumeurs osseuses de haut degré de malignité.
    Notes: Summary We have assessed the value of adding low dose radiotherapy to preoperative chemotherapy in 20 patients with high grade malignant bone tumours. Histology of the resected specimens showed a considerable tumouricidal effect and a distinct capsule enclosing the extraosseous part of the tumour. There were no serious side effects.
