    Notizen: Three cases of semicircular lipoatrophy are described.Semicircular lipoatrophy (lipoatrophia semicircularis) is a relatively new entity, three cases having been recently described by Gschwandtner & Miinzberger (1974). Clinically the patients present with horizontal depressions symmetrically distributed on both upper thighs, characteristically on the antero-lateral aspects. We are presenting three cases (the first in the English literature). Cases 1 and 2 are sisters and this is of particular interest because a familial tendency has not previously been reported.

    Beschreibung / Inhaltsverzeichnis: Résumé Les auteurs décrivent une méthode d'évaluation globale du pied, tant avant qu'après correction chirurgicale, chez des adolescents porteurs d'hallux valgus. Elle nécessite une série d'études des caractéristiques cliniques, photographiques et radiologiques, ainsi qu'une évaluation dynamique de la marche à l'aide d'un plateau de force. Cette méthode a été utilisée pour estimer avec exactitude les modifications survenues sur 36 pieds après que l'hallux valgus ait été traité par une variante de l'ostéotomie oblique du premier métatarsien décrite par Wilson, qui consiste en une résection d'un coin osseux suivie de fixation par une vis. Durant les six premiers mois post-opératoires, on note un déplacement de l'appui de l'avant-pied vers le dehors et une diminution de la charge au niveau des orteils, mais il y a une tendance à revenir à la répartition pré-opératoire de l'appui au cours des quatre années suivantes. La persistance du déplacement externe de l'appui semble résulter de la surélevation de la tête du premier métatarsien, conséquence du raccourcissement de cet os créé par l'ostéotomie. Ceci peut être évité en abaissant délibérément la première tête métatarsienne lors de l'opération et en fixant les fragments par une vis dans la position désirée.
    Notizen: Summary A comprehensive method of evaluating the feet of patients with adolescent hallux valgus both before and after surgical correction is described. Serial clinical, photographic and radiological studies were made and a dynamic assessment of gait was carried out using a load-sensitive walkway. Observations were made on 36 feet in which hallux valgus was treated by a modification of the Wilson oblique metatarsal osteotomy, with removal of a wedge of bone and screw fixation. In the first six months after operation, there was a lateral shift of the weight-bearing pattern in the forefoot and less weight was taken on the toes, but there was a tendency to return to the pre-operative distribution of weight during the next four years. Persistence of the lateral shift of weight-bearing appeared to result from elevation of the first metatarsal head secondary to shortening of the first metatarsal during the osteotomy. This can be avoided by deliberate depression of the first metatarsal head at the time of operation and fixation of the fragments in the required position with a screw.

    Notizen: A brief description of the Molecular Modeling System-X graphics system hardware is followed by an explanation of the language which has been developed to realize an `electronic Richards box'. A variety of commands permits the construction and manipulation of a protein model within an electron density distribution. Usually about ten amino-acid residues can be displayed at any one time within a box of 20 grid points on an edge. The density is changed automatically as the viewer translates the model off the edge of the screen. He can then add, subtract or modify residues as appropriate.

    Notizen: [Auszug] The two types of Drosophila melanogaster rDNA insertion occur at different sites in the 28S gene, separated by 51 nucleotide pairs. A short segment of rDNA is deleted at the site of the 5 kilobase type I insertion, whereas there is no such deletion of rDNA sequences which flank the type II ...

    Notizen: Summary The neuronal response to complete cerebral ischemia (CCI) of 5–15 min duration was evaluated at the light and electron microscopic level subsequent to postischemic recirculation periods of up to 60 min. Following postischemic reperfusion, the homogeneous neuronal changes characteristic of permanent CCI were modified into a heterogeneous pattern of selectively vulnerable neuronal responses. Four basic types of neuronal injury were represented within this heterogeneous neuronal population. The Type I neuronal response was most numerous and consisted of chromatin clumping, nucleolar condensation and a breakdown of polysomes. This response may represent a reversal of some of the neuronal changes observed after permanent CCI. In addition to the above changes, Type II neurons contained swollen mitochondria and Golgi saccules which appeared as microvacuoles under the light microscope. Type III neurons displayed varying degrees of neuronal shrinkage and numerous swollen mitochondria. Type IV neurons were markedly shrunken and electron-dense with few identifiable subcellular structures. The distribution of Type I neurons was random but the other neuronal responses occurred in “selectively vulnerable” brain regions. The number of Type II, III, and IV neurons increased with extended insult durations but were unaffected by the length of recirculation. Ten minutes of CCI represented the threshold for a significant increase in the number of severely altered neurons. These findings suggest that considerable neuronal injury may be present after 10–15 min of CCI, and the lack of a recirculation period following CCI appears to afford the brain parenchyma an extensive degree of structural protection.

    Notizen: Summary The prevalence of serum leukocyte-reactive antinuclear antibody (LR-ANA) was determined in 31 patients with ankylosing spondylitis (AS), their age-and gender-matched normal controls, and two tribes of 340 West Coast Canadian Indians (Bella Coolas and Haidas). At a serum dilution of 1:10, the prevalence of LR-ANA in AS and controls was 45% and 7%, respectively. At 1:20 dilution, the prevalence was 23% in AS, 0% in controls, 29% in Bella Coolas and 27% in Haidas. No concordance was found among LR-ANA, HLA-B27 and CREG-B7, and nine HLA-A and seven HLA-B antigens in the Indian tribes. These studies confirm an increased prevalence of LR-ANA in AS and AS kindreds. but the latter association appears to be independent of HLA antigens.

    Notizen: Abstract During the spring and summer of 1979, 48 species of geofungi and several sterile, unidentified fungi were isolated from two off-shore stations on the Bay of Fundy, Canada. Isolations were made from subsurface water and surface slicks on 6 agar media including one containing hexadecane, and from subsurface water baited with hemp seeds. Numbers of fungi were 10 to 100 times higher than those reported for other offshore stations and similar to those reported for a saltmarsh outflow. Species isolated during a high freshwater flow largely corresponded to a typical soil flora. Species isolated during a reduced freshwater flow were either marine in character or noted for association with area littoral seaweeds. Three fungi (Cladosporium cladosporioides, Trichoderma viride, and Gliocladium rosium) were tested for growth on media of increasing salinity. Growth was measured by dry weight production, pH drop and glucose used in liquid culture. C. cladosporioides showed responses typical of a marine fungus, T. viride of a terrestrial fungus and G. roseum was intermediate. The results are discussed in relation to the role of geofungi in the sea.
