    Notes: Koluchova's on-going study of twin boys who suffered extreme deprivation between 18 months and 7 yr, and who thereafter received remedial treatment, is discussed in the context of relevant literature. Malnutrition, cruelly, neglect and considerable isolation over 51/2 yr did not predestine them permanently to the condition of severe subnormality which they manifested on discovery. Their greatly accelerated development confirms similar work and sheds some light on the interaction of constitutional and environmental factors in the formation of human characteristics. Results underline the inadequacy of theories stressing the over-riding importance of early experiences for later growth.

    Notes: [Auszug] Our method depends on the fact that the geomagnetic threshold rigidity R and therefore the velocity of cosmic rays arriving from the east is lower for negatively charged primaries than for positive primaries. This difference is greatest in the equatorial zone. The detector (Fig. 1) consists of a ...

    Description / Table of Contents: Sommaire Des comparaisons de réactions de l'E.M.G. et du myogramme dans un réflexe d'allongement phasique entre la tension normale au repos (contrôle) et trois conditions de prétension, montrent: (1) qu'il y a un rapport positif, linéaire entre ces deux variables, mais que le coefficient de corrélation décroît avec l'augmentation en puissance de la pré-tension; (2) quand le rapport est tracé, les lignes de régression pour le contrôle et la pré-tension se séparent, mais les inclinaisons pour les régressions ne sont pas dissimilaires; (3) il y a une diminution progressive dans la différence de réactions avec l'augmentation en force de la pré-tension; (4) il y a un grand coefficient de corrélation ‘produit-moment’ entre la force maximale du myogramme et la région du myogramme. Les explications de ces résultats sont discutées en termes de physiologie des fuseaux musculaires.
    Abstract: Zusammenfassung Vergleiche der EMG und Myogrammreaktionen in einem phasischen Streckungsreflex zwischen normaler Ruhespannung (Kontrolle) und drei Zuständen vor einer Spannung zeigen dass: (1) eine positive lineare Verbindung zwischen diesen beiden Veränderlichen besteht, dass aber der Korrelationskoeffizient mit Vergrösserung der Kraft der Vorherspannung abnimmt; (2) die Regressionslinien für Kontrolle und Vorherspannung sich trennen, wenn das Verhältnis graphisch dargestellt wird, dass aber die Neigungen der Regressionen nicht unähnlich sind; (3) eine fortschreitende Abnahme in der Veränderung der Reaktionen mit Steigerung der Vorspannungskraft erfolgt; und (4) ein grosser Produkt-Moment Korrelations koeffizient zwischen der Spitzenkraft des Myogramms und der Fläche des Myogramms existiert. Erklärungen für diese Ergebnisse werden in Form von Muskelspindelphysiologie besprochen.
    Notes: Abstract Comparisons of the EMG and myogram responses in a phasic stretch reflex between normal resting tension (control) and three pre-strain conditions show that (i) there is a positive, linear relationship between these two variables but the correlation coefficient decreases with increase in force of pre-strain, (ii) when the relationship is plotted, the regression lines for control and pre-strain separate but the slopes for the regressions are not dissimilar, (iii) there is a progressive decrease in the variance of responses with increase in force of pre-strain and (iv) there is a high product-moment correlation coefficient between the peak force of the myogram and the area of the myogram. Explanations for these results are discussed in terms of muscle spindle physiology.

    Notes: Abstract The basal lactic acid concentration is higher in the gastric juice of Australian patients than in a similar Japanese population. A gastric juice lactic acidosis is associated with advanced gastric carcinoma in both groups. The extent of the gastric juice lactic acidosis in gastric carcinoma appears to be related to the size of the carcinoma. There was no correlation between lactic acid concentration and acid output, suggesting that atrophic gastritis is not a major determinant of the lactic acid concentration.
