    Notes: In a series of 250 renal biopsies (transplants excluded) the diagnosis of membranous glomerulonephritis was made in 22. This was done on light microscopy in 17, while the addition of immunofluorescence enabled the diagnosis to be made in a further five. Electron microscopy confirmed the diagnosis in all cases. Immunoperoxidase studies emphasized the basement membrane distribution of the deposits of immunoglobulin and the relative sparing of the mesangium. They showed at an ultrastructural level the presence of IgG in the deposits.

    Notes: Fillets cut from pre-rigor codling and frozen singly were observed to shrink rapidly whilst thawing. This paper describes a series of experiments investigating this phenomenon of thaw rigor and its control by manipulation of temperature in cold storage.

    Notes: [Auszug] Group O Rh-negative red cells were washed six times in saline and treated with glutaraldehyde followed by lysine, as previously described15. These cells were added to an equal volume of fresh serum and incubated at 37 C for 2-24 h. Control samples contained lOmMEDTA. Aliquots of the supernatant ...

    Notes: Abstract Observations are reported from 7 years of breedingM. arctoides in a small caged colony. From a stock of two males and six females 18 offspring have been born and 17 reared despite leaving young with the mother for approximately 2 years and restricted access between sexes. Overt menstrual bleeding is inconspicuous and external signs of oestrus are minimal. Colour change and slight swelling indicate the cycling condition, not the stage of the oestrous cycle. Mean length of cycles was 29.4 days. Copulatory ties have been observed on 15 occasions. Pregnancies lasted 168–183 days. The mean of five exactly timed pregnancies was 178 days. Pregnant animals became lethargic during the last two months of gestation. Nipple enlargement occurred during some pregnancies and females sucked and manipulated their nipples expressing milk. This was also seen in two non-pregnant females caged beside nursing mothers. All 17 successful births occurred at night. Caging mother, latest offspring, and previous offspring together proved successful. Mothers tolerated quite extensive investigation of the newborn by her previous baby, and the interactions that develop subsequently. Older female siblings frequently direct components of maternal behaviour to their younger sibling. Males showed marked interest in young in neighbouring cages, giving the soft “grunt-purr” typically shown to white furred young by adults other than the mother. The age of menarche of females born in the laboratory has steadily decreased through the period of captivity. Sexual behaviour is first seen long before puberty in both sexes, some aspects of its development are described. Two sub-adult males appeared to have failed to develop mature sexual behaviour until it was found that their incompetence was a reversible effect of the presence of an adult male.

    Description / Table of Contents: Sommaire La génération d'un électromyogramme peut être mise en modèle par le filtrage linéaire des trains d'impulsionsN, considérés en tant qu'entrées neurales des unités motricesN, ou l'e.m.g. représente la somme des sorties des filtresN. En prenant ce modèle comme point de départ, on peut constater que non seulement les configurations des images potentielles de l'actionN, vues par les électrodes, représentent un facteur important pour l'établissement de la définition du spectre d'électromyogramme, mais que la distribution des intervalles entre-crête des trains d'impulsions le sont également. Similairement, on peut constater que les modifications d'ordre statistique des trains d'impulsions affectent l'extrémité de basse-fréquence du spectre de puissance, même si les potentiels actifs de l'unité motrice ne changent pas de configuration. Cet effet est illustré par l'utilisation de donées déjà publiées qui se rapportent aux aspects des muscles deltoides et des bicep brachiaux. Une méthode est également présentee, qui consiste à incorporer la synchronisation de l'unité motrice et, à cet égard, on constate que l'effet de cette dernière peut être possiblement à l'inverse de celle qui est engendrée par les statistiques des temps d'allumage.
    Abstract: Zusammenfassung Die Erzeugung eines EMG kann durch lineares Filtern einerN-Impulsserie im Modell dargestellt werden, die als neurale Eingaben fürN-motorische Einheiten angesehen werden, wobei das EMG die Summe der Ausgaben von denN-Filtern ist. Ausgehend von diesem Modell wird gezeigt, daß die Formen der durchN-Wirkung hervorgerufenen Potentialbilder, die von den Elektroden abgelesen werden, nicht nur einen bedeutenden Faktor in der Begrenzung des Spektrums darstellen, sondern daß dies auch für die Intervall- verteilung der Impulsserien zwischen den Spitzen zutrifft. Änderungen inder Statistik der Impulsserien wirken sich erwiesenermaßen auf die Nieder-frequenzseite des Kraftspektrums aus, selbst wenn die Aktionspotentiale der motorischen Einheiten ihre Form nicht ändern. Die Wirkung wird durch Einsatz von bereits veröffentlichten Daten über den Deltamuskel und die Brachialmuskeln dargestellt. Ein Mittel zum Einschluß der Synchronisation von motorischen Einheiten wird vorgestellt, und eswird gezeigt, daß seine Wirkung entegengesetzt zur Auslösungsstatistik liegen kann.
    Notes: Abstract The generation of an e.m.g. can be modelled by linear filtering of N impulse trains, regarded as the neural inputs to N motor units, where the e.m.g. is the sum of the outputs of the N filters. Starting from this model, it is shown that not only are the shapes of the N action potential images as viewed by the electrodes an important factor in defining the spectrum, but so is the interspike interval distribution of the impulse trains. Changes in the statistics of the pulse trains are shown to affect the low-frequency end of the power spectrum even if the motor-unit action potentials do not change shape. The effect is illustrated by use of data already published on deltoid muscle and brachii biceps. A means of including motor-unit synchronisation is introduced and it is shown that its effect can be contrary to that due to the firing statistics.
