Um Charakteristika gleicher Fragen in Gesundheitsumfragen im Zusammenhang mit interkulturellen Unterschieden im Verständnis dieser Fragen zu identifizieren, analysieren die Verfasser Befragungen zum Gesundheitssystem, wobei die Befragten vier verschiedene kulturelle Subgruppen in den USA repräsentieren (weiße Nicht-Hispanics, Afroamerikaner, mexikanische Amerikaner und Puerto Ricaner) mit Hilfe des Instruments des Behaviour Coding. Untersucht werden die Auswirkungen von vier Merkmalen der Fragebogenkonstruktion auf kulturelle Schwierigkeiten beim Verständnis der Fragen. Die empirische Datenbasis bilden 13514 Antworten von 345 Befragten auf 42 Fragen. Es zeigt sich, dass das Antwortformat, die Länge der Frage sowie das Lese- und Abstraktionsniveau der Fragen einen wesentlichen Einfluss auf das Verständnis der Fragen bei den Befragten haben. Die Kultur der Befragen hatte einen moderierenden Einfluss auf die Effekte von Antwortformat, Fragenlänge und Leseniveau. Verschiedene Aspekte des Fragebogendesigns, die den Fragebogen allgemein verständlicher machen sollen, haben ebenfalls kulturspezifische Auswirkungen. (ICEÜbers)

SYNOPSIS. Gamogony of Theileria ovis Rodhain occurs within the gut of nymphs of the tick Rhipicephalus evertsi evertsi Neumann. After molting, spherical and ovoid parasites are found within the intestinal cells of the ticks. These stages are thought to be zygotes, because they undergo a transformation process leading ultimately (in 3 days) to the formation of a motile stage, the kinete, the fine structure of which is very similar to that of the ookinetes of the hemosporidia. The kinete leaves the gut cells of the tick and penetrates the salivary gland cells where it produces infective stages (the sporozoites). These stages may be transmitted to sheep during the next blood meal of the tick. The developmental processes of T. ovis are compared to those of Hemosporina.

SUMMARY— Specific antibodies were developed against skeletal muscle from horse, pork, lamb and beef. The antigenic protein material evaluated for antibody production included actomyosin, serum-alum precipitate, muscle extract-alum precipitate, saline extract of muscle and freeze-dried water extract of muscle. The method of injection into the rabbits included intraperitoneal, intravenous, subcutaneous, and intramuscular with and without Freund complete adjuvant.Of the antigenic protein material and route of injection evaluated, the intramuscular injection of 150 mg of freeze-dried water extract of muscle with Freund complete adjuvant resulted in the highest titers which were observed as the titer increased and with time after injection as indicated by ring and gel diffusion tests. However, these cross-reactions could be-removed by absorption with small amounts of the freeze-dried protein extracts of the cross-reacting species. A specific antiserum for each animal specie could be obtained which would react with 0.4–0.5 mg/ml of protein in a saline extract of skeletal muscle.Overall, multiple intramuscular injections of freeze-dried water extracts of skeletal muscle emulsified in Freund complete adjuvant resulted in the highest titers which would react specifically with each animal species.

The use of circular object targets is very common in spatial photogrammetric object reconstruction. An object circle is projected on to the image plane as an ellipse if the object plane and the image plane are not parallel to each other. The image co-ordinates of the centre of the ellipse are usually determined automatically by means of digital image processing. These co-ordinates are then used as observations for a subsequent reconstruction of the three dimensional object point. The image co-ordinates of the centre of the ellipse and the true co-ordinates of the projected centre of the circular object target are not identical; thus eccentricity is caused, resulting in systematic geometric image measurement errors. This paper describes the functional context of this eccentricity for a typical target/camera set-up. The possible solutions for a correction of this systematic eccentricity error are derived. Guidelines for the correct combination of object target sizes and exposure distances, guaranteeing reliable image point measurements and accurate object point determination, are proposed.

The lbi (lipopolysaccharide biosynthesis interfering) RNA of phage Acm1, an untranslated RNA transcript of 97 nucleotides, previously shown to affect O-polysaccharide biosynthesis in various Escherichia coli strains, was found to downregulate the synthesis of the d-galactan II component of the O-specific polysaccharide in Klebsiella pneumoniae serotype O1. Enzymatic and Pb2+ probing experiments revealed that lbi RNA consists of two consecutive stem–loop structures, the 5′-proximal hairpin loop of 15 nucleotides being particularly accessible to single strand-specific probes. Based on the assumption that the 5′-proximal hairpin loop may be involved in an antisense interaction with cellular target RNAs, we randomly mutagenized one or two of its central nucleotides. Expression of mutated lbi RNA variants in K. pneumoniae serotype O1 relieved at least partly the repression of d-galactan II formation. In addition, a truncated version of lbi RNA lacking the 3′-proximal hairpin loop was almost as efficient as the wild-type RNA in downregulating d-galactan II synthesis. The results obtained indicate that the 5′-proximal hairpin loop of lbi RNA functions as a key structural element in the mechanism leading to the inhibition of d-galactan II biosynthesis in K. pneumoniae serotype O1.

SUMMARY –A simple, rapid method for the qualitative identification of animal proteins as to species was developed for fresh meat. Gamma globulin isolated from species-specific rabbit antiserum was mixed with a heated extract of skeletal muscle of beef, horse lamb and pork. The mixture was allowed to set for 30 min at room temperature and then centrifuged. The presence of a precipitin indicated a positive reaction. There were no cross reactions between meat samples from different species. This method requires a maximum time of only 1–2 hr, as compared with the 3 days required for double-gel diffusion. In addition, it is much more sensitive than gel diffusion.

[Auszug] Helicobacter pylori infection causes gastric pathology such as ulcer and carcinoma. Because H. pylori is auxotrophic for cholesterol, we have explored the assimilation of cholesterol by H. pylori in infection. Here we show that H. pylori follows a cholesterol gradient and extracts the lipid from ...
