Resolving Cross-modal Semantic Interference among Object Concepts Requires Medial Temporal Lobe Cortex.

The ability to flexibly categorize object concepts is essential to semantic cognition because the features that make two objects similar in one context may be irrelevant and even constitute interference in another. Thus, adaptive behavior in complex and dynamic environments requires the resolution of feature-based interference. In the current case study, we placed visual and functional semantic features in opposition across object concepts in two categorization tasks.

[30-day mortality after heart surgery: a pilot project of the Working Party of Directors of Hospital Cardiology Departments].

Background And Objective: 30-day mortality after operation is generally accepted as a central standard of quality, especially in regard to cardiac operations. The Working Party of Directors of Hospital Cardiology Departments (Arbeitsgemeinschaft Leitender Kardiologischer Krankenhausärzte, ALKK) in Germany set up a pilot project to analyse whether by direct communication with patients by a database centre the expenditure incurred in collecting complete data can be decisively reduced and full documentation of outcome can in this way be obtained even for a large multi-centre patient cohort.

Patients And Methods: Between 1.

The cytomorphological spectrum of mantle cell lymphoma is reflected by distinct biological features.

Mantle cell (centrocytic) non-Hodgkin's lymphoma (MCL) is a malignant tumour with unique biological features. The pathogenesis of MCL seems to be strongly associated with aberrant function of the cell cycle. 110 cases of MCL have been analysed for their cytomorphological features, mitotic and proliferation indices, bcl-1 rearrangements, p53 expression patterns and DNA content by both interphase cytogenetic as well as DNA flow cytometric analyses.

[Porphyrin-induced biliary cirrhosis in protoporphyria: indications for liver transplantation].

A 51-year-old patient, who had experienced photosensitivity from childhood on, fell ill with an icterus accompanied by abdominal complaints. At the age of 46 years an erythropoietic protoprophyria had been diagnosed by an excessive protoporphyrinemia. Meanwhile, in consequence of the protoporphyria's erythrohepatic progression, a biliary liver cirrhosis developed, associated with portal hypertension and marked splenomegalie.

[Liver transplantation in erythrohepatic protoporphyria].

A 51-year-old man had for 5 years been known to have erythropoietic protoporphyria. GPT levels were raised up to 40 U/l, gamma-GT up to 120 U/l. After lengthy exposure to sun radiation an erythema with blisters, abdominal discomfort and jaundice developed (total bilirubin 7.

[The determination of protein hydrophobicity. 2. Determination of the of protein binding of sodium dodecyl sulfate with the use of the ultracentrifuge].

The interaction between sodium dodecylsulphate (SDS) and the proteins bovine serum albumin (BSA) and ovalbumin, respectively, was studied using a synthetic boundary cell of an ultracentrifuge. A method for the determination of protein-bound SDS is described. The SDS binding capacity of BSA is found to be 250 +/- 50 micrograms SDS per 500 micrograms of BSA.

[The determination of protein hydrophobicity. 1. Determination of the hydrophobicity of selected cereal and milk proteins using their sodium dodecyl sulfate binding capacities].

The sodium dodecylsulphate (SDS) binding capacities of secalin, gliadin and gluten in the presence of a very low SDS concentration were determined and compared to the SDS binding capacities of bovine serum albumin (BSA), beta-lactoglobulin, ovalbumin und beta-casein. The SDS binding capacities of endosperm proteins determined in phosphate buffer (pH 6.0) are very low.
