    Notes: Coupling of soft magnetic films to antiferromagnetic substrates was studied by spin-polarized secondary electron microscopy. Permalloy (Ni80Fe20 alloy) films were deposited on antiferromagnetic NiO(111) single-crystal substrates. A domain structure consisting of fine grains (∼50 μm) was characteristic of the NiFe film deposited without applying magnetic field. The domain image and its response to applied field suggested existance of local easy axis and local unidirectional anisotropy. When macroscopic unidirectional anisotropy was introduced to the NiFe film by depositing under an applied dc magnetic field, many of the fine grains disappeared and the film showed large domains (∼1 mm). In the large domains, small elongated reversed domains (∼20 μm×60 μm) aligned parallel to each other implying local easy axis of magnetization. The type of domain behavior described above was not observed in a NiFe film on MgO(111) substrate that had the same crystal structure as NiO but no magnetic ordering. An x-ray analysis revealed that the local easy axes observed in NiFe/NiO specimens coincided with the [112¯] of the NiO crystal lying in the (111) substrate plane, which supported coupling of the NiFe film with the single-crystal substrate. © 1997 American Institute of Physics.

    Fabricating nanoscale magnetic mounds using a scanning probe microscope : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: Nanometer-scale mounds were fabricated by applying voltage pulses between a substrate and an atomic force microscope cantilever coated with magnetic material. Mounds were formed on both insulator and conducting substrates. Magnetic force microscopy (MFM) observations of the fabricated mounds were performed, and the contrast was turned over by reversing the magnetization of the tip, which is convincing proof that the mounds are magnetic. The MFM images also suggest that the mounds are perpendicularly magnetized. These results demonstrate that scanning probe microscope based nanofabrication is a promising method to fabricate nanoscale magnetic dots on any kind of substrates. © 1996 American Institute of Physics.

    A gibberellin-regulated protein phosphorylated by a putative Ca2+-dependent protein kinase is G-protein mediated in rice root (2005)

    Notes: The GA-signal transduction pathways downstream to the Gα protein in rice seedling root were investigated using in-gel kinase assay and in vitro protein phosphorylation techniques with a Gα protein defective mutant, d1. A 50-kDa protein kinase was detected downstream to Gα protein in the membrane fraction of rice seedling roots using an in-gel kinase assay with histone III-S as a substrate. The activity of a 50-kDa protein kinase increased in the wild-type rice by gibberellin (GA3) treatment, but did not change in the d1 mutant. This protein kinase activity was inhibited by the Ca2+ chelator ethyleneglycol-bis-(beta-aminoethylether)-N,N,N 1,N 1-tetraacetic acid (EGTA), protein kinase inhibitors, staurosporine and H7, and calmodulin antagonist, trifluoperazine, suggesting that the 50-kDa protein kinase is a putative plant Ca2+-dependent protein kinase (CDPK). The activity of the 50-kDa putative CDPK reached its highest level at 3 h after GA3 treatment and then gradually declined with time. In order to identify the endogenous substrate for 50-kDa putative CDPK, two-dimensional polyacrylamide gel electrophoresis followed by in vitro protein phosphorylation was carried out. The phosphorylation activity of an endogenous protein PP30, identified as an unknown protein having molecular weight 30 kDa and isoelectric point 5.8 was increased in the wild-type rice by GA3 treatment, compared with the d1 mutant. The addition of GA3 treated membrane fraction, which predominantly represent a 50-kDa putative CDPK further increased the phosphorylation of PP30. Almost similar to GA3 treatment, phosphorylation activity of PP30 was also increased by the treatment with cholera toxin in the wild-type rice but not in d1 mutant. These results suggest that the 50-kDa putative CDPK and an unknown protein, PP30 promoted by GA3 treatment are G-protein mediated in rice seedling roots.

    Combination Rule of Σ Values at Triple Junctions in Cubic Polycrystals (1996)

    Notes: In cubic polycrystals, combinations of coincidence orientation relationships at a triple junction of grains A, B and C can be obtained by using the equation ΣCA = ΣABΣBC/d2, where d is a common divisor of ΣAB and ΣBC. This paper describes the derivation of this equation and shows several models of polycrystals composed of specially selected coincidence boundaries using the above equation.

    Notes: Abstract Rupture of tumors is usually a critical and life-threatening condition. We demonstrate a wide variety of ruptured tumors with their imaging characteristics including gastric lymphoma, gastric leiomyosarcoma, leiomyosarcoma of the ileum, hepatocellular carcinoma, pancreatic pseudocyst, renal angiomyolipoma, renal cell carcinoma, ovarian endometrial cyst, ovarian corpus luteum cyst, and ovarian teratoma. Their imaging features are illustrated with an emphasis on clues to an accurate diagnosis.

    Studies on interdomain interaction of 3-isopropylmalate dehydrogenase from an extreme thermophile, Thermus thermophilus, by constructing chimeric enzymes (1999)

    Notes: Abstract In our previous study, we showed that a chimeric isopropylmalate dehydrogenase, 2T2M6T, between an extreme thermophile, Thermus thermophilus, and a mesophile, Bacillus subtilis, isopropylmalate dehydrogenases (the name roughly denotes the primary structure; the first 20% from the N-terminal is coded by the thermophile leuB gene, next 20% by mesophile, and the rest by the thermophile gene) denatured in two steps with a stable intermediate, suggesting that in the chimera some of the interdomain interaction was lost by amino acid substitutions in the "2M" part. To identify the residues involved in the interdomain interactions, the first and the second halves of the 2M part of the chimera were substituted with the corresponding sequence of the thermophile enzyme. Both chimeras, 3T1M6T and 2T1M7T, apparently showed one transition in the thermal denaturation without any stable intermediate state, suggesting that the cooperativity of the conformational stability was at least partly restored by the substitutions. The present study also suggested involvement of one or more basic residues in the unusual stability of the thermophile enzyme.

    Notes: Abstract This paper describes a transumbilical resection and umbilical plasty for treatment of a patent omphalomesenteric duct (POMD). In a newborn infant with a POMD, a skin incision was made circumscribing the mucocutaneous junction of the protruded duct. The duct was completely extirpated with a wedge resection of the connection to the intestine and an umbilical plasty was performed. The postoperative appearance was excellent. It appears that transumbilical resection and umbilical plasty may be a satisfactory operation for POMD.

    Infarcted intestinal volvulus detected by prenatal ultrasonography (1996)
    Springer
    Pediatric surgery international 11 (1996), S. 498-499 
    Details
    ISSN: 1437-9813

    Notes: Abstract This article describes a prenatal ultrasonographic finding of an infarcted intestinal volvulus. Ultrasonography showed polyhydramnios, multiple dilated intestinal loops, increased transverse abdominal area, and ascites. After cesarean section due to premature rupture of membranes and fetal distress, derotation of the infarcted volvulus caused postoperative thrombocytopenia, hyperkalemia, and acidosis and a subsequent resection was required. A high output of intestinal juice from the jejunostomy caused severe hypovolemia and electrolyte imbalance with resultant death. Increased transverse abdominal area caused by marked intestinal dilatation, ascites, fetal distress, and hydrops fetalis may suggest an infarcted intestinal volvulus.
