    Notizen: Thin films of giant magnetostrictive materials were formed by dc magnetron sputtering and ion beam sputtering processes. A systematic investigation was made to examine the effect of these deposition processes on the magnetic properties and magnetostriction of TbFe2 and (Tb, Dy)Fe2 thin films. The magnetostriction of the films formed by dc sputtering was in the range from 200 to 400 ppm at a magnetic field H=15 kOe, whereas the films formed by the ion beam sputtering exhibited a slightly higher magnetostriction. For both processes, the increase in Ar partial pressure in the deposition processes strongly changed magnetic anisotropy from perpendicular to in plane, and increased magnetostriction and magnetostrictive response at low magnetic fields. However, the mixture of Xe gas into Ar gas in the dc sputtering lowered magnetization and gave almost no effect on magnetic anisotropy. © 2000 American Institute of Physics.

    Notizen: MgO thin films were prepared by ion plating systems and by an ion beam sputtering system with a plasma filament type ion source. Triode-type and rf ion plating processes were employed. MgO films were prepared with various oxygen partial pressures ranging from 10−3 to 10−2 Pa. In the triode-type ion plating process, the MgO(200) was the preferred growth orientation of film. In the rf ion plating process, MgO(111) and (220) reflection peaks appeared in the x-ray diffraction patterns of films. The films were transparent, and those values of transmittance of ultraviolet region were increased as increasing oxygen partial pressure. In the ion beam sputtering process, the film showed amorphous structure and low transmittance. © 2000 American Institute of Physics.

    Useful applications of DNA repair tests for differential diagnosis of atypical dyschromatosis symmetrica hereditaria from xeroderma pigmentosum (2001)

    Notizen: Dyschromatosis symmetrica hereditaria (DSH) is a hereditary skin disease characterized by the presence of pigmented and hypopigmented macules on the extremities and freckles on the face. However, if clinical features are not fully developed in infantile patients, it is difficult to differentiate DSH from xeroderma pigmentosum by clinical features alone. A 2-year-old boy (patient 1), revealed atypical features of DSH with slight susceptibility to sunburn. However, his grandfather (patient 4) who was 67 years old, revealed typical features of DSH, which helped to make an exact diagnosis in patient 1. For patient 2, a 5-year-old boy, and patient 3, a 3-year-old girl, it was more difficult to make a diagnosis because there were no family members with DSH features. DNA repair ability was tested for all four cases by means of unscheduled DNA synthesis and colony formation of skin fibroblasts after ultraviolet light irradiation, which resulted in an accurate diagnosis of DSH. We propose that these tests be performed to make a diagnosis of DSH in the case of poor or atypical clinical symptoms.

    Oxidative Stability, Structure, and Physical Characteristics of Microcapsules Formed by Spray Drying of Fish Oil with Protein and Dextrin Wall Materials (2003)

    Notizen: : Maltodextrins and a highly branched cyclic dextrin (HBCD) were tested for their ability to serve as wall materials for microcapsules with proteins. HBCD or a maltodextrin of DE18 with sodium caseinate (SC) improved the oxidative stability of encapsulated fish oil; however, the DE18/SC wall system had 2 disadvantages: browning induced by the Maillard reaction and agglomeration. The oil load level and the selection of dextrin strongly affected the outer topography and the inner structure, as well as the ratio of the oil to dextrin on the surface of the microcapsules. It is stated that drying speeds of dextrin and oil load levels were shown to be likely related to the structural difference in the microcapsules.

    Emulsifying and Surface Properties of Wheat Gluten under Acidic Conditions (2001)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 66 (2001), S. 0

    Notizen: The solubility of wheat gluten was greatly improved at pH 4 or lower where it showed good emulsifying activity. This might be due to its high surface activity in the acidic pH range and the formation of a stable protein film surrounding the oil droplets. Among the major gluten proteins, gliadins showed higher surface activity than glutenins. The content of glutenins in the adsorbed protein film was higher than that of gliadins, and glutenins are likely to have been adsorbed more tightly than gliadins. These results suggest that gluten proteins exhibit complex behavior, such as adsorption/desorption/displacement/rearrangement during the adsorption process in a gluten-stabilized emulsion.

    EFFECTS OF TORASEMIDE ON RENAL HAEMODYNAMICS AND FUNCTION IN ANAESTHETIZED DOGS (1991)

    Notizen: 1. We examined the effects of torasemide (0.3 and 1 mg/kg i.v.) on renal haemodynamics and function employing renal clearance and stop-flow techniques in anaesthetized dogs and compared these with furosemide (1 and 3 mg/kg i.v.).2. Torasemide and furosemide did not influence renal haemodynamics, in the renal clearance study, but caused a dose-related and significant increase in urine flow and urinary excretion of sodium and potassium. Torasemide and furosemide increased fractional excretion of sodium in the distal tubules with a relatively small increase in the fractional excretion of lithium (index of sodium excretion at the proximal tubules, FELi). The diuretic profile of torasemide was of long duration, compared with that of furosemide.3. Torasemide and furosemide inhibited sodium reabsorption at the distal portion of the tubules in the stop-flow study.4. It is suggested from these results, that the main diuretic site of action of torasemide is the ascending limb of the loop of Henlé.

    Degradation pathway of kinins in tumor ascites and inhibition by kininase inhibitors: Analysis by HPLC (1990)

    Notizen: Abstract We have recently found presence of a high concentration of a novel type of kinin, hydroxyprolyl3-bradykinin (Hyp3-BK) in human tumor ascites in addition to conventional bradykinin (BK). Because of their potential physiological activity, it is of interest to know how these bradykinins can be degraded in ascites. Degradation of two synthetic kinins, BK and Hyp3-BK, added to the ascitic fluid from patients with ovarian carcinoma and hepatoma, were analyzed by reversed phase HPLC. Both kinins were degraded into their desArg9-BK or-Hyp3-BK and desPhe8-Arg-9-BK or-Hyp3-BK products following incubation with the ascitic fluid. The rate of the degradation of BK and Hyp3-BK was the same. The formation of desArg9-BK was completely inhibited by kininase I inhibitor, while the formation of desPhe8-Arg9-BK was not completely inhibited by a kininase II inhibitor. The degradation of both kinins was inhibited completely by EDTA. The results indicate the presence of other metalloprotease(s) which cleaves kinins in the ascitic fluid, in addition to kininase I and kininase II. The carboxypeptidase A and carboxypeptidase B inhibitor, benzyl malic acid, failed to block degradation of both kinins. A rapid cleave of Phe-Arg into Phe and Arg was also found in the ascitic fluid. Thus, the major degradation products of kinins in the ascitic fluid were demonstrated to be either desArg9-BK or Hyp3-BK, desPhe8-Arg9-BK or-Hyp3-BK, phenylalanine and arginine. Lysyl-BK and lysylhydroxyprolyl3-BK were rapidly converted into BK and hydroxyprolyl3-BK by the ascitic fluid.
