    Notes: A method has been developed for investigating the chemical reactions of organic compounds under the dynamic shock loading conditions of detonation. Sealed capsules are placed along the axis of a cylindrical charge which is initiated at one end. As the detonation wave progresses along the charge, a major part of the sample inside each capsule is subjected to a well-balanced annular compression with peak pressure approximately equal to the Chapman–Jouguet pressure of the explosive used. The geometry of the system ensures both minimal structural deformation and low residual velocity of the capsules; consequently high survival rates have been obtained. The temperature and pressure distribution within the sample space has been calculated as a function of time by a computer simulation using MAGI, a three-dimensional Smooth Particle Hydrodynamics code. The temperature has also been measured experimentally with a variety of organic reactions known to be insensitive to pressure, whose Arrhenius parameters are obtained from the literature and measurements in our laboratory. © 1995 American Institute of Physics.

    Notes: Fingerprint whorl patterns are formed during fetal life. In a group of 180 term infants, those with more fingerprint whorls tended to have a small abdominal circumference (P= 0.09) and high ratio of head to abdominal circumference (P= 0.008). These associations were independent of the relation between the whorl counts of the mothers and their infants. We also found an independent correlation between the babies’ whorl count and the combination of increasing subscapular (P= 0.03) and decreasing triceps (P= 0.02) skinfold thicknesses of the mothers. Whorl patterns are associated with adult hypertension; maternal nutritional status may influence their common origin during fetal development.

    The effect of atenolol, a p!-adrenergic antagonist, on nocturnal plasma melatonin secretion: Evidence for a dose-response relationship in humans (1997)

    Notes: Nathan PJ, Maguire KP, Burrows GD, Norman T.R. The effect of atenolol, a β1-adrenergic antagonist, on nocturnal plasma melatonin secretion: Evidence for a dose-response relationship in humans. J. Pineal Res. 1997; 23:131–135. © Munksgaard, Copenhagen〈section xml:id="abs1-1"〉〈title type="main"〉AbstractPineal β1-adrenergic receptors are involved in the regulation of melatonin secretion. The involvement of β1adrenergic receptors has been demonstrated by the ability of acute administration ofβ-antagonists to suppress the nocturnal rise of circulating melatonin and its urinary metabolite 6-sulphatoxymelatonin (aMT6s). The present study was undertaken to examine the relationship between increasing doses of atenolol and nocturnal plasma melatonin concentrations. Six healthy subjects participated in the study for a period of 5 weeks. Subjects were administered placebo, 12.5, 25, 37.5, and 50 mg doses of atenolol in a randomized single blind design. Each dose was separated by a 1 week washout period. Blood samples were collected at regular intervals from 19.00 hr to 06.00 hr. Repeated measures analysis of variance showed a dose-dependent decrease in plasma melatonin concentrations (P 〈 0.01). A Student Newman-Keuls post hoc test indicated significant differences between placebo and all doses of atenolol (P 〈 0.05). The results demonstrate a dose-dependent relationship between β1-receptor blockade and suppression of nocturnal plasma melatonin in humans.

    Notes: Abstract The static dielectric constant of liquid acetonitrile is reported at 10, 25, and 40°C and at pressures up to 3 kbar. Densities of pure acetonitrile were measured where needed in order to analyze the dielectric measurements using the Kirkwood-Fröhlich equation. The Kirkwood correlation factorg K was found to be less than unity with a positive temperature but negative pressure coefficient, suggesting an increasing anticorrelation of dipoles with decreased temperature and increased pressure. Theg K factors are analyzed by a dipole pair-bonding model as outlined by Dannhauser and Flueckinger in which the lowg K values are attributed to the presence of dimers consisting of completely anticorrelated dipoles. The implication of this model on other measurements, especially MNR relaxation studies, is examined.
