    Notes: Summary The effects of low and high NaCl diets on plasma glucose and insulin responses to glucose ingestion were investigated in 15 patients with essential hypertension. Oral glucose (75 g) tolerance tests were carried out while patients were taking diets with low (2 g/day) and high (20 g/day) NaCl content. Fasting plasma glucose and insulin levels were both significantly lower during ingestion of the high NaCl diet (p〈0.05). After glucose ingestion, the incremental areas under the two hour plasma glucose and insulin curves were significantly smaller during ingestion of the high NaCl diet (glucosep〈0.005 and insulinp〈0.025). These findings that low NaCl diets increase the glycemic response to glucose loads suggest that use of NaCl restriction for the treatment of essential hypertension may not always be desirable.

    MR imaging of intracranial vertebral artery occlusion (1989)

    Notes: Summary Magnetic resonance (MR) images of nine patients with intracranial vertebral artery occlusion (five proved, four presumed) have been reviewed. In two of nine, both vertebral arteries were occluded and in five of the nine, the basilar artery was also blocked. All occluded arteries showed absence of flow void and were clearly demonstrated as mildly hypo-∼mildly hyperintense structures to brainstem parenchyma on the T1-weighted images. In two of five patients with basilar artery occlusion, retrograde filling of the distal basilar artery was detected. Thus, MR imaging, in particular the T1-weighted image, is a pertinent diagnostic modality for evaluating intracranial vertebral artery occlusion. Angiography does not seem to be required for confirmation.

    Effects of lesion of the interstitial nucleus of Cajal on vestibular nuclear neurons activated by vertical vestibular stimulation (1986)

    Notes: Summary 1. Experiments were performed in cats anesthetized with nitrous oxide to study the effects of INC lesions on responses of vestibular nuclear neurons during sinusoidal rotations of the head in the vertical (pitch) plane. Responses of neurons in the INC region were recorded during pitch rotations at 0.15 Hz. A great majority of these neurons did not respond to static pitch tilts, and they seemed to respond either to anterior or to posterior semicircular canal inputs with a peak phase lag of 140 deg (re head acceleration). 2. Responses of vestibular nuclei neurons in intact cats were recorded during pitch rotations at the same frequency (0.15 Hz). Neurons that seemed to respond to vertical semicircular canal inputs showed peak phase lags of 90 deg relative to head acceleration, whereas neurons that responded to static pitch tilts showed peak phase shifts near 0 deg. These results indicate that responses of neurons in the INC region lag those of vestibular neurons by about 50 deg, suggesting that the former neurons possess a phase-lagging (i.e. integrated) vestibular signal. 3. Responses of vestibular neurons in cats that had received electrolytic lesions of bilateral INCs 1–2 weeks previously were recorded during pitch rotations at the same frequency (0.15 Hz). Neurons that presumably responded to vertical semicircular canal inputs showed a peak phase lag of 60 deg relative to head acceleration, a significant decrease of the phase lag compared to normal, whereas responses near 0 deg were unchanged. Gain values of individual cells also significantly dropped from 2.07 ± 0.67 spikes · s−1/deg · s−22 (mean ± SD; normal cats) to 1.27 ± 0.68 spikes · s−2/deg · s−2 (INC lesioned cats) at 0.15 Hz. When responses of vestibular neurons were studied during pitch rotations in the range of 0.044–0.49 Hz in these cats, a large decrease of the phase lag was observed at lower frequencies, whereas the slopes of phase lag curves of vestibular neurons in intact cats were rather flat. 4. Procaine infusion into the bilateral INCs not only resulted in a decrease of 20–50 deg in the phase lag in responses of vestibular neurons that had lagged head acceleration by 90–140 deg before procaine infusion, but also dropped the gain of the response to rotation by an average of 31%, whereas responses of neurons that had showed phase shifts near 0 deg were not influenced consistently. Simultaneous recording of the vestibular neurons and the vertical vestibuloocular reflex (VOR) indicated that the phase advance and gain drop of vestibular neurons occurred earlier than those of the VOR. These results exclude the possibility that the change in dynamic response of vestibular neurons after procaine infusion is due to depression of general brain stem activity that may lead to the phase advance of the VOR, and suggest that the decrease of the phase lag and gain drop in responses of the vestibular neurons was caused by removal of the phase-lagging, feedback signal coming from the INC to the vestibular nuclei.

    Notes: Abstract We study X-ray and Auger emission spectra from initial core holes which are strongly influenced by many-electron effects of giant Coster-Kronig type. In particular we include the dynamics of relaxation and decay processes in a systematic manner both in the spectral function of the initial-state core-hole (self-energies) and in the emission matrix elements (vertex corrections). We explicitly demonstrate that proper dressing of the emission matrix element guarantees that the sum of all branching ratios become unity (conservation of probability). Finally, we present numerical calculations of the 4p −1−4d −1 X-ray emission spectrum in Xe, illustrating the importance of a systematic treatment of self-energy and vertex corrections.

    Notes: Abstract Theg-Hartree method is adapted to the direct ab-initio calculation of atomic transition energy. For the improvement of numerical accuracy the newg-Hartree code is developed and used for the calculations of atomic ionization energies of selected levels of small atoms He(Z=2), Be(Z=4), Ne(Z=10), Mg(Z=12) and Ar(Z=18). The results are very similar to those obtained in a previous work. The agreement between theory and experiment is excellent.

    Notes: Abstract The Ca 3s, Kr 4s, Sr 4s and Yb 5s atomic ionization spectra are calculated using the one-particle Green's function method within the framework of Random phase approximation with exchange. Pronounced final ionic correlation effects are found for these levels. The relative intensity of the main ionic state is reduced considerably byns −1↔np −2 nd super Coster Kronig process. The ionization energy of the main ionic state is shifted as much as ∼4 eV from the relativistic Hartree-Fock ΔSCF ionization energy byns −1↔np −2 nd super Coster-Kronig process. The existence of strongnp −2 nd 2 S satellite is predicted for these levels.

    Notes: Abstract New results on the high resolution spectrum of ArI in the 3s-subshell excitation region are reported. The spectra are recorded in the second order of a 3-meter vacuum spectrograph and synchrotron radiation as the background source of continuum. The transitions: $$\begin{array}{*{20}c} {3s^2 3p^6 {}^1S_0 \to 3s({}^2S_{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} )3p^6 np} & {{}^1P_1 (4 \leqq n \leqq 25)} \\ \end{array} $$ have been extended to highern-values and more accurate level positions and binding energy of the 3s-subshell is achieved from the series limit. The spectrum has been analysed within the framework of non-relativistic Hartree-Fock and relativistic Hartree-Fock calculations. Intensity anomalies aroundn=9 have been atributed to an additional level arising from doubly excited state 3s 23p 44s4p.

    Notes: Abstract The atomic total energies of the four-electron isoelectronic series are calculated by theg-Hartree 2nd order perturbation theory and the Dirac-Hartree-Fock-Rayleigh-Schrödinger 2nd order perturbation theory. The Coulomb correlation energy is calculated by these theories. The Breit interaction, vacuum polarization, self-energy and Q.E.D. corrections are calculated by the lowest order approximation. The results show that theg-Hartree approach overestimates the Coulomb correlation energy. However, with an increase of the nuclear charge, it overestimates much less. In the case of the Hartree-Fock 2nd order calculation, it underestimates the Coulomb correlation energy. With an increase of the nuclear charge, it underestimates much more.

    Notes: The pore size for a fine porous freeze-dried cellulose acetate membrane was evaluated by gas separation methods, where the Present-deBethune equation was applied. Separation coefficients were referred to the calculated value for each pore size from this equation. Nuclepore, Millipore VS, and Millipore VC, whose pore sizes were already known by bubble point method, were tested for this method. Pore diameters for this cellulose acetate membrane, thus determined, were about 25 and 40 Å from Ar-Kr and N2-Kr separation systems, respectively, which agreed well with the results from electron microscope (50 Å) and N2 gas permeability (50 Å). However, it is impossible to apply this method to He gas separation, since He gas permeability is higher than the expected value as Knudsen flow, which indicates that some channels are existing in this membrane, where He gas is more permeable than the other gases.
