    Notes: The magnetic properties of CoCrPt/CoCrPtSi dual-magnetic-layered thin films are investigated in terms of the crystalline microstructures using a vibrating-sample magnometer, transmission electron microscope, and scanning electron microscope. The magnetic crystal grains of the films are aligned with forming chainlike clusters. Each stacked magnetic crystal grain is epitaxially grown on individually isolated columnar Cr crystals with a relationship of hcp (101¯1)Co-based alloy //bcc (110)Cr. The direction of magnetic easy axes of two stacked magnetic crystals are aligned in a same direction. Single-crystalline dual-magnetic-layered thin films, which are epitaxially grown on MgO(110) single-crystal substrates, are prepared to estimate the Ku of the dual-layered magnetic grains. The Ku is determined to be 4×106 erg/cm3, whose value is about 2 times as large as that of single-layered CoCrPtSi. This large anisotropy energy is presumed to lead the increase of Hc in the dual-layered magnetic films.

    Magnetic and crystallographic properties of CoCrPt thin films formed on Cr–Ti single crystalline underlayers : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: By using an epitaxial growth technique, Co73Cr15Pt12(112¯0) bi-crystalline thin films formed on Cr–Tix(001)[x=0–15 at. %] single crystalline underlayers were prepared to investigate the relationship between the magnetic properties and the lattice distortion in the magnetic layer. X-ray diffraction measurement shows that the best lattice matching between the c axis of the CoCrPt and the [110] direction of the Cr–Ti underlayer is realized and the CoCrPt layer shows an ideal symmetrical hcp. structure when the Ti concentration is 10 at. %, where the maximum magneto-crystalline anisotropy energy and coercivity values are observed. Distortion in the hcp. CoCrPt magnetic crystal grains decreases the uniaxial magneto-crystalline anisotropy energy, thus lowering the attainable medium coercivity. © 1996 American Institute of Physics.

    Effect of magnetic field cooling and magnetization anomaly in magnetic fluids near melting point (1988)

    Notes: The magnetization process of ferrofluids with carrier fluids of water, paraffin, and alkylnaphtalene was investigated in a temperature range from 77 to 300 K as functions of the freezing rate and the intensity of cooling magnetic fields. A uniaxial magnetic anisotropy is induced by field cooling in frozen ferrofluids. This induced anisotropy which is caused by the formation of clustering of magnetic particles disappears on heating near the melting point. The magnetization of the frozen fluids exhibits an anomalous increase below the melting point of the carrier fluids. In a frozen state, no relative motion of particles, such as Brownian motion, occurs. With increasing temperature, the inhibited motion will be released gradually by the recovery of viscosity. The anomaly may be related to glassy transition and premelting. These magnetic properties are discussed in terms of mesoscopic phase transition between liquid and solid.

    Immunohistochemical detection of pregnancy and placental proteins in human and cynomolgus monkey (macaca fascicularis) peripheral blood cells (1981)

    Notes: Summary With use of an enzyme-bridge immunoperoxidase method, the localization of pregnancy-specific β1-glycoprotein (SP1), pregnancy-associated proteins (SP2, SP3) and placental tissue proteins (FSF, PP1, PP2 and PP4 to PP12) was investigated in human and cynomolgus peripheral blood cells. Blood cells of cynomolgus monkeys revealed the same staining results as in man: SP1, SP2, SP3, PP2, PP4, PP6, PP7, PP8, PP10 and PP12 were found to be positive in the polymorphonuclear neutrophils. Monocyte macrophages stained positively only for PP2 and PP10. Lymphocytes and erythrocytes did not stain positively for any of the proteins examined. A much stronger positive staining for SP2 and SP3 was found in the polymorphonuclear neutrophils from a human female taking contraceptive pills and pregnant cynomolgus monkeys. Otherwise there was no difference in staining results irrespective of whether the specimens were from males, or pregnant or non-pregnant females. The results reported here indicate that the so-called placenta-“specific” proteins SP1, PP10 and PP12 are apparently also synthesized by normal blood cells and appear to be not specific to the placenta. Only PP5 and PP11 seem to be highly specific to the trophoblast.

    Description / Table of Contents: Summary By using an immunoglobulin enzyme bridge (PAP) technique, the location of two ubiquitous tissue proteins (PP8, PP9) and three placental specific tissue proteins (PP10, PP11, PP12) was investigated in ethanol/acetic acid-fixed paraffin-embedded human term placentae. PP8 was found mainly in both the cytoplasm and the nucleus of trophoblast cells (chorion) and syncytiotrophoblast (villi). PP9 was found in the cytoplasm of trophoblast cells (chorion), the fibrous part of interstitial connective tissues (villi), and the cytoplasm of histiocytes (villi, amnion, and decidua). PP10 was found in the cytoplasm of epithelium (amnion) and in both the cytoplasm and the nucleus of syncytiotrophoblast (villi). PP12 was found in the cytoplasm of histiocytes in decidua, amnion, and chorion and the cytoplasm of syncytiotrophoblast (villi). In addition, stains for PP8, PP10, and PP12 were taken up by the cytoplasm of histiocytes found in amnion, villi, the intervillous space, and decidua, in contrast to PP11, which was found to be specific to the cytoplasm of trophoblast cells (chorion and villi). Possible clinical applications of these findings are discussed.
    Notes: Zusammenfassung Mit Hilfe einer Immunglobulin-Enzym-Brücken-(PAP-) Technik wurde die Lokalisation von zwei neuen ubiquitären Gewebsproteinen (PP8, PP9) und von drei neuen plazentaspezifischen Gewebsproteinen (PP10, PP11, PP12) im Gewebe reifer menschlicher Plazenten untersucht: PP8 war hauptsächlich im Zytoplasma und in den Zellkernen der Trophoblastzellen (Chorion) und des Synzytiotrophoblasten (Villi) lokalisiert; PP9 im Zytoplasma der Trophoblastzellen, im fibrösen Teil des Stromas (Villi) und im Zytoplasma von Histiozyten (Villi, Amnion und Dezidua), PP10 im Zytoplasma des Epithels (Amnion) sowie im Zytoplasma und in Zellkernen des Synzytiotrophoblasten (Villi), PP12 im Zytoplasma von Histiozyten in Dezidua, Amnion und Chorion sowie im Zytoplasma des Syncytiotrophoblasten (Villi). PP11 wurde ausschließlich im Zytoplasma von Trophoblastzellen (Chorion und Villi) aufgefunden und scheint für den Trophoblast hochspezifisch zu sein, während PP8, PP10 und PP12 zusätzlich im Zytoplasma einiger Histiozyten des Amnions, der Villi, des intervillösen Raumes und der Dezidua nachgewiesen wurden. Die mögliche klinische Bedeutung dieser Plazentaproteine wird diskutiert.

    Notes: Summary Using conventional radioimmunoassay kits, we measured concentrations of two cancer-related antigens, tissue polypeptide antigen (TPA) and cancer antigen 125 (CA125) throughout gestation and at delivery. The maternal serum was collected from 147 pregnant women between 5 and 43 weeks gestation and 27 women were studied at delivery at which time samples of maternal blood, umbilical artery and vein blood as well as amniotic fluid were collected. The various concentrations of TPA and CA125 were compared with placental weight and infant birth weight. The results are summarized as follows: (1) Mean TPA levels in maternal serum increased with advancing gestation and rose above 110 U/l (upper non-pregnant limit) from 35 weeks onwards. Mean CA125 levels rose above 35 U/ml (normal non-pregnant upper limit) before 9 weeks gestation and thereafter fell. Both levels were markedly raised immediately after delivery. (2) In umbilical artery and vein serum, mean TPA levels were slightly raised. However, there were no significant differences between TPA levels in maternal serum and matched serum from the umbilical artery and vein. Mean umbilical CA125 levels were below 35 U/ml, while mean CA125 levels were significantly higher in the corresponding maternal serum. (3) The concentrations of TPA and CA125 were extremely high in amniotic fluid. The mean values reached 3604 U/l and 2187 U/ml, respectively. (4) None of the concentrations of TPA and CA125 in those pregnancy-related body fluids correlated significantly with birth weight, placental weight or fetal sex. These findings suggest that the production of these two cancer-related antigens is not by the fetus but the placenta.
