    Notes: Summary The evolution of glucose assay methods has been central to the development of present therapies for diabetes mellitus. However, new blood glucose assay capabilities, such as convenient and truly continuous monitoring, are now needed to foster a new era of close blood glucose control. The principles and present status of glucose sensors being developed that may fill these requirements are reviewed here. [Diabetologia (1997) 40: S 102–S 107]

    Notes: Measurement of distribution of velocities of phases in pipe flow of a dense gas-solid suspension was facilitated by the use of an ion source in the form of a localized corona discharge and a downstream traversing electrostatic probe. The system utilizes the transient behavior of a corona discharge which provides a distinction of times of arrival of ions and solid particles of modified charges at a downstream probe. This probe system does not suffer the handicap of other available probe systems in a dense solid phase.

    Notes: Empirical modeling of the dependence of loop voltage on edge plasma conditions in the reversed field pinch is discussed. Specific concerns are raised regarding magnetohydrodynamic-based models that assume a large local dissipation of magnetic helicity at the plasma edge. A kinetic model is presented in which loop voltage can be affected by fast electrons carrying momentum directly to the walls or limiters, without a large edge helicity dissipation.

    Notes: Steady-state current sustainment by oscillating field current drive (OFCD) utilizes a technique in which the toroidal and poloidal magnetic fields at the plasma surface are modulated at audio frequencies in quadrature. Experiments on the ZT-40M reversed field pinch [Fusion Technol. 8, 1571 (1985)] have examined OFCD over a range of modulation amplitude, frequency, and phase. For all cases examined, the magnitude of the plasma current is dependent on the phase of the modulations as predicted by theory. However, evidence of current drive has only been observed at relatively low levels of injected power. For larger modulation amplitudes, the data suggest that substantial current drive is offset by increased plasma resistance as a result of modulation enhanced plasma–wall interactions. The initial experimental results and supporting theoretical interpretations of OFCD are discussed.

    Notes: Ovarian function was assessed by measuring plasma gonadotrophins, urinary oestrogen and urinary pregnanediol levels, every week for four weeks, in 34 women, aged 45 to 57 years, after withdrawal of oral contraceptive therapy. A rise in urinary pregnanediol excretion occurred in 14 patients suggesting that ovulation had occurred and that these patients were‘premenopausal'. Elevated serum gonadotrophin values and persistently low urinary oestrogen and pregnanediol excretion occurred in 13 patients suggesting ovarian failure or a‘postmenopausal’state. However, one apparently‘postmenopausal’patient later showed hormonal evidence of ovulation, indicating fluctuation in ovarian function. There were 7 patients with‘indeterminate’hormone profiles whose ovarian function was difficult to assess. All patients excreting more than 45 nmol of oestrogen a day had a spontaneous period within 45 days of stopping hormone therapy.

    Notes: Moderate water stresses in the range 0 to −0.6 MPa applied with PEG 6000 to excised roots of Zea mays L. var. LG 11 induced increases of up to four-fold in the amount of abscisic acid (ABA) determined in the tissue after a 12 h period of xylem exudation. The ABA concentration of xylem exudate collected after a 2 h water stress also increased by up to four-fold. Salt stresses, induced with NaCl solutions, resulted in similar increases in the ABA concentrations. ABA concentrations in both root tissue and xylem exudate were highest 4 h after removal of the stress and then declined over a subsequent 8 h period. These results are interpreted in support of the concept that root-produced ABA may have a role in the fine control of the plant's water balance.

    Description / Table of Contents: Zusammensetzung Wir haben nachgewiesen, daß neugeborene Mäuse oral mit Herpes simplex-Virus Typ 2 infiziert werden können. Bei unseren Mäusen trat keine transplazentäre oder transvaginale Übertragung des Herpes simplex-Virus Typ 2 auf. Das Ausbleiben einer natürlichen transvaginalen Infizierung bei Mäusen läßt sich durch die relativ kurze Expositionszeit gegenüber dem Virus während des Geburtsvorgangs erklären. Diese Versuche zeigen, daß hohe orale Dosen von Herpes simplex-Virus Typ 2 bei Mäusen eine disseminierte Neonatalinfektion bewirken können und diese Versuche daher bei künftigen Untersuchungen des Mechanismus und der Behandlung dieser Krankheit möglicherweise von Nutzen sind.
    Notes: Summary We have demonstrated that newborn mice can be infected orally with herpes simplex virus type 2. Transplacental and transvaginal transmission of herpes simplex virus type 2 did not occur in our mice. Failure to produce natural transvaginal infection in mice may be explained by the relatively short period of exposure to the virus during parturition. These experiments demonstrate that high oral doses of herpes simplex virus type 2 can produce disseminate herpes neonatal infection in mice and therefore may be useful in future investigations into the mechanism and the treatment of this disease.

    Notes: [Auszug] Coleus is particularly suitable for an investigation of this kind because the main vascular bundles are situated at the angles of the square stem. We used CaldwelFs split root technique on Coleus frederici. Cuttings were taken and a fortnight later the rooted stumps were carefully split from the ...
