Based on releves and observations from the GDR, Czechoslovakia, Jugoslavia and USSR and on the literature, the spreading and phytosociology of Ailanthus altissima in the synanthropic area, ...connections between area-development, phytosociological pattern, and the hemerobic indicator value are elaborated.
A new molecular variant of alpha1-antitrypsin was discovered in the family of a woman with severe antitrypsin deficiency and bullous emphysema. The variant resembles the Z variant in most respects in ...that it results in severe antitrypsin deficiency with the homozygous state and intermediate deficiency with the heterozygous state, and is associated with diastase-resistant, periodic acid-Schiff-positive globules in the liver cells. It differs from the usual Z variant, however, by having normal mobility on acid-starch electrophoresis so that the heterozygous state with the normal M form cannot be distinguished by phenotyping procedures on either acid-starch or alkaline-agarose electrophoresis. The variant has been labeled MDUARTE. A review of phenotype patterns in all patients previously classified as having a homozygous ZZ phenotype reveals extra, fast-moving bands on acid-starch suggestive of an MDUARTEZ heterozygous state in 7.9 per cent of such cases. When intermediate antitrypsin deficiency occurs in the presence of a normal phenotype pattern, one must consider that the patient has inherited either a null gene for antitrypsin synthesis or an MDUARTE variant.

1. Nearly all livers at autopsy contain fat which is histologically demonstrable. 2. Fatty substances in the liver appear chiefly in two forms, as small granules and as globules of various sizes. 3. ...We suppose that granules indicate the (protoplasmic) change commonly spoken of as fatty degeneration, and that globules of small size are excess of fat, stored up by reason of some pathological change which may be merely temporary. 4. Fat is oftenest central, least often in the mid-zone. 5. A heavy deposit of fat is compatible with a competent liver. 6. Intense fattiness, generally globular, occurs with intoxications of bacterial and chemical nature, as well as in cases where a complex toxin is manufactured by the body-cells. 7. Granular fat occurs oftener than globular: it affects most often the central zone; globular affects most often the peripheral. 8. " Accidental " masses of globular fat are found at times, and appear to follow no rule of position: these are comparable to lipomata, which are evidently the result of a pathological process. 9. We found no deposit of fat characteristic of uremia. 10 We know of no analysis of the liver fats in the granular and globular states respectively: it seems to have been taken for granted that the deposits were one and the same. To determine the relationship, if any, between these two forms should be the basis of investigation.

Mathematical methods are used to study certain related Logo procedures in detail. Simple procedures with known properties are then used to build the higher-level procedures which correspond to ...higher-level mathematical concepts. Examples are from introductory aspects of number theory. (MNS)
Functional programming, in which the connection to mathematics is simple and direct, is described. A language such as Logo illustrates the relationship between functional programming and mathematics ...in more detail. (MNS)
Development of an erythematous, papulonodular to papulopustular skin eruption in four febrile, immunocompromised patients raised the possibility of a systemic mycosis when Gram's stains of unroofed ...lesions disclosed budding yeasts. Candidiasis, torulopsosis, sporotrichosis, and cryptococcosis were considered in the differential diagnosis, and therapy with amphotericin B was begun. Skin biopsy specimens disclosed fungi to be located exclusively within intact and ruptured hair follicles. Inability of the fungi to grow on media that were not supplemented with lipid and their structure and location all suggested the presence of Pityrosporum sp. When hematogenous dissemination of a mycosis to the skin is suspected, the diagnosis must be based on biopsy specimen demonstration of dermal invasion, ideally with positive cultures. Pityrosporum sp, common skin saprophytes, may produce folliculitis, and be mistaken for pathogenic yeasts.
