    Spin-wave resonance investigations of Ni-ion implanted Permalloy films : 37th Annual conference on magnetism and magnetic materials (1993)

    Notes: Spin-wave resonance (SWR) has been applied to investigate the influence of Ni-ion implantation onto the magnetic properties of Permalloy films. The implantation has been carried out at room temperature with different doses at Ni-ion energies of 95 keV. In films of 30–60 nm thicknesses, which are thin compared to the implantation range, with increasing dose the uniform mode is shifted to higher resonance fields in the parallel configuration. In the perpendicular configuration one obtains a shift to lower fields. The corresponding variation of the effective magnetization as a function of the implantation dose could be reproduced by assuming a change of the average volume magnetization. In thicker films (150–250 nm) standing spin waves are excited which are only slightly modified by implantation compared to the as-prepared samples. The observed effects can be attributed to changes of the surface anisotropy.

    Notes: Abstract— Glucose metabolism in the superior cervical ganglion for calves has been studied by incubating slices with [1-14C]-, [6-14C]- and [U-14C]-labelled glucose at 37°C and pH 7.4. Glucose utilization and the metabolic partitioning of glucose carbon in products during different incubation periods ranging from 5 to 60 min were determined by isotopic methods.Separation and identification of labelled compounds have been achieved by anion and cation exchange chromatography as well as by TLC and enzymatic analyses.From the data obtained a carbon balance could be constructed showing lactate to be the major product of glucose metabolism followed by CO2 and amino acids. Measuring the release of 14CO2 from differently 4C-labelled glucose, the existence of an active pentose phosphate pathway in the ganglion could be demonstrated although this pathway seems to contribute only to a small extent to glucose metabolism. The marked decrease of the C-U: C-6 and the C-U:C-1 ratios in 14CO2 observed in the course of incubation is discussed in terms of a time-dependent change in the rate of synthesis of amino acids which are directly connected with intermediates of the citric acid cycle.

    Description / Table of Contents: Summary 1. Washed human erythrocytes metabolize 1,14μMol xylitol in 120 min under the following experimental conditions: pH 7.4 and 37° C. 2. The levels of 2,3-diphosphoglycerate and ATP decrease during the incubation with xylitol. This decrease is not a specific effect of xylitol, but depends on the amount of C-atoms taken up. This could be shown in control experiments with fructose and glucose as substrates given separated or in combination with xylitol. The highest uptake of C-atoms has been observed with glucose plus xylitol as substrate. 3. 99% of the metabolized xylitol was recovered in the products lactate, Co2 and D-xylulose. 4. There was no measurable oxalate production from xylitol.
    Notes: Zusammenfassung 1. Gewaschene, menschliche Erythrozyten verstoffwechseln unter experimentellen Bedingungen (pH 7,4, 37° C) 1,14μMol Xylit in 120 min. 2. Der 2,3-DPG- und ATP-Spiegel fällt während der Inkubation mit Xylit ab. Dieser Abfall ist keine spezifische Wirkung des Xylits, sondern hängt von der Menge der aufgenommenen C-Atome ab. Dies zeigten Vergleichsuntersuchungen mit den Substraten Fruktose und Glukose allein und in Kombination mit Xylit. Die höchste Aufnahme an C-Atomen wurde mit Glukose+Xylit als Substrat erreicht. 3. Der verstoffwechselte Xylit wurde zu 99% in den Produkten Laktat, CO2 und D-Xylulose wiedergefunden. 4. Eine Oxalatbildung aus Xylit konnte nicht nachgewiesen werden.

    Notes: Abstract. Fe/Al multilayers are prepared by crossed-beam pulsed laser deposition and investigated by Rutherford backscattering, conversion electron Mössbauer spectroscopy, and transmission electron microscopy. The results are compared to purely ballistic simulations of the deposition process using the TRIDYN4.0 code. It is found that the intermixing of adjacent layers must be described in terms of ballistic mixing followed by chemical mixing. The phase formation in the transition layer between adjacent layers follows the non-equilibrium behavior of Fe/Al in analogy to investigations on mechanically alloyed and ion-beam-mixed Fe/Al. In Fe-rich areas a bcc solid solution is formed. In Al-rich environment an amorphous phase is observed.

    Comparison of xylitol and glucose metabolism in nonhepatic rat tissues (1976)

    Description / Table of Contents: Zusammenfassung Es wurde untersucht, ob und in welchem Ausmaß eine Reihe isolierter, nicht-hepatischer Rattengewebe Xylit verwerten. Nur die Nierenschnitte waren in der Lage, Xylit signifikant zu verwerten, während bei Schnitten von Lunge, Hirn, Herz- und Skelettmuskulatur sowie bei Fettzellen weder mit enzymatischer Analytik noch mit Isotopentechniken eine Xylitaufnahme direkt nachweisbar war. Übereinstimmend mit diesem Ergebnis war der Einbau von Radioaktivität aus [U-14C]-Xylit in CO2 und Lactat außer bei den Nierenschnitten sehr gering und verglichen zum Einbau aus Glucose (=100%) weniger als 5%. Aus den Ergebnissen wird geschlossen, daß, abgesehen von der Leber, nur die Niere in der Lage ist, Xylit zu verwerten, während er für die anderen untersuchten Organe keine geeignetes Substrat darstellt.
    Notes: Summary Capability and extent of xylitol metabolism in vitro was studied in a variety of non-hepatic tissues of rats, using enzymatic and isotopic methods. Only kidney was found to be able to utilize xylitol at a significant rate while in all other organs tested — lung, brain, heart muscle, skeletal muscle and adipose tissue — no uptake of xylitol was detectable using two independent methods. In accordance with these results the incorporation of radioactivity from [U-14C]-xylitol as substrate into the products CO2 and lactate was found to be very small in all organs with the exception of kidney and when compared to that from [U-14C]-glucose it was less than 5%. From these results it is concluded that besides liver only kidney can utilize xylitol to a significant extent while for the other tissues studied xylitol is not a suitable substrate.
