T1 - Leistungsprognose bei jugendlichen Spitzensportlern N2 - Im vorliegenden Beitrag wird der Versuch gemacht, neuere Befunde der kognitiven Psychologie, insbesondere der Expertiseforschung, zur Entwicklung außergewöhnlicher Fertigkeiten und Kenntnisse auf den Bereich des Sports zu übertragen und damit deren Generalisierungsmöglichkeiten zu prüfen. In einem ersten Schritt werden dabei die Grundannahmen der traditionellen fähigkeitsorientierten Leistungsprognose mit denen der neueren Expertiseforschung verglichen und im Hinblick auf ihre empirische Bewährung untersucht. Der zweite Schritt besteht darin, daß mögliche Parallelen zwischen der Entwicklung kognitiver und sportlicher Expertise aufgezeigt und an Fallbeispielen demonstriert werden. Dies leitet zum Schwerpunkt des vorliegenden Beitrags über, der in einer Reanalyse von Daten besteht, die im Rahmen einer fünfjährigen Längsschnittstudie an jugendlichen deutschen Tennistalenten gewonnen wurden (vgl. Rieder, Krahl, Sommer, Weicker & Weiss, 1983). Da in dieser Untersuchung sowohl Daten zur Entwicklung allgemeiner motorischer Basisfähigkeiten wie auch zur Entwicklung sportartspezifischer Fertigkeiten erhoben worden waren, ließ sich die Bedeutsamkeit dieser beiden Komponenten für den sportlichen Erfolg relativ genau bestimmen. Weiterhin waren Informationen zu Hintergrundmerkmalen wie z.B. der elterlichen Unterstützung, der Trainingsintensität sowie Merkmalen der Motivation und Konzentration verfügbar, von denen anzunehmen war, daß sie zusätzlich dazu geeignet sein sollten, individuelle Unterschiede in den beobachteten Entwicklungsverläufen zu erklären.

A1 - Seidel, E. A1 - Richter, P. T1 - Geochemical characteristics of metabasites in different tectonic units of the North-East-Bavarian crystalline basement N2 - Comprehensive geochemical investigations of rnetabasites yielded constraints for a correlation of, or discrimination between the different tectonic units within the northeast Bavarian crystalline basement. The Münchberg nappe pile consists of at least five large tectonic units which exhibit differences in lithology, in part also in metamorphie grade and in metamorphie history. The metabasites in each of these nappes show their own, significant geochemical characteristics. The lowermost tectonic unit, the Bavarian lithofacies, includes the anchimetamorphie Ordovician Randschieferserie which contains alkaline basalts. In their geochemistry, they are sirnilar to the metabasites of the Fichtelgebirge crystalline complex in the autochthonous Saxo-thuringian. The next higher tectonic unit of the Münchberg nappe pile, the Prasinit-Phyllit-Serie contains metabasites which can be derived from subalkaline basalts with a clear calc-alkaline tendency. There is a striking geochemical resemblance to the metabasites of the Erbendorf Greenschist Zone (EGZ) underscorinq the similar lithology of both allochthonous units which appear to be in a similar tectonic position. The Randamphibolit-Serie higher up in the Münchberg nappe pile consists of metabasites with tholeiitic characteristics and a pronounced differentiation trend. The next higher tectonic unit, the Liegendserie of the Münchberg gneiss cornplex s. str., contains metagabbros to metagabbronorites with a high-Al basaltic composition. The amphibolites and banded hornblende gneisses of the overlying Hangendserie are of subalkaline basaltic character with calc-alkaline affinity. The Zone Erbendorf-Vohenstrauss (ZEV) is currently regarded as an allochthonous unit equivalent to the higher crystalline nappes of the Münchberg pile. However, the geochemical character of the metabasites do not encourage such a correlation. Neither the schistose and striped amphibolites nor the flaseramphibolites of the ZEV with their N-KORB and E-MORB character respectively, find convincing counterparts in the crystalline nappes of the Münchberg pile. However, an interestingly close resemblance exists between the schistose and striped amphibolites in the ZEV, on the one hand, and in the autochthonous Zone Tirschenreuth- Mähring (ZTM) and the adjacent Moldanubian sensu strictu, on the other. Owing to the absence of age criteria, our results cannot be used, so far, to reconstruct the paleogeographical position of the individual tectonic units, based on the geochemical characteristics of their respective metabasites.

T1 - In-vitro assays to detect alkylating and mutagenic activities of dietary components nitrosated in situ N2 - Nitrosation of dietary components has been combined with the 4-(para-nitrobenzyl)pyridine (NBP) colorimetric test for screening alkylating agents and with the Ames test for the detection of mutagenic activity. This allowed the investigation of short-hved nitrosation products of dietary components which generate electrophilic degradation products requiring no metabolic activation (natural amino acids and some derivatives, ureas, guanidines, primary alkyl and aryl amines). In a first system, precursor, nitrous acid and NBP were present simultaneously. All amino acids tested, except glutamic acid and glutamine, gave positive results. The reactivities spanned more than three orders of magnitude, with the aromatic amino acids and methionine the most active; two primary amines, tryptamine and histamine, were also strongly reactive. All guanidines tested, except the amino acid arginine, gave negative results. A second system consisted of two phases: NBP was added only after destruction of residual nitrite and adjustment of the pH to neutrality. This system was useful for the study of ureas, which are stable in acid but not in neutral media. The range of responses covered more than two orders of magnitude. Most amino acids and primary amines also gave positive results, but could be assessed only after analysing the kinetics of the competing reactions and choosing appropriate reaction times. In a third system, Salmonella typhimurium strain TA1OO replaced NBP. Representatives of the class of amino acids, ureas, the primary amine tryptamine, and aniline became higbly mutagenic upon nitrosation. Methylguanidine was only weakly mutagenic under the present assay conditions. The results indicate that further studies with unstable nitrosation products of dietary components are required to understand more thoroughly the role of endogenous nitrosation in gastric cancer.

T1 - Alkylating potency of nitrosated amino acids and peptides N2 - Tbe alkylating potency of unstable N-nitrosamino acids and N-nitrosopeptides was investigated in vitro using 4-(para-nitrobenzyl)pyridine (NBP) as nucleophile. Of the amino acids, Met and those with an aromatic side chain were the most potent. The relative overall alkylating potency was 23:10:5:4:2:1: for Trp, Met, His, 1)rr, Phe and Gly, respectively. The homo-dipeptides were much more potent than the amino acids, with relative potencies of 400:110:100:8:3:1, for Trp-Trp, l)T-'I)T, Met-Met, Asp-Asp, Phe-Phe and Gly, respectively. In the one-phase reaction system (in which NBP is already present durlog the nitrosation reaction at acidic pH), all amino acids tested showed a second-order reaction for nitrite. In the two-phase system (in which NBP is added only after bringing the nitrosation reaction mixture to neutrality), all amino acids tested except one again showed a second-order reaction for nitrite (Phe, His, Asp and the dipeptide artiticial sweetener aspartame); only Met under these conditions bad a reaction order of one for nitrite. This could mean that nitrosation of the side chain of Metproduces a second N-nitroso product which is relatively stable in acid but reacts with NBP under neutral conditions. In the human stomach, this side-chain nitrosation might become more important than the reactions at the primary amino group, firstly because of the greater stability of the product(s) in acid and secondly because of the tirst-order reaction rate for nitrite. A decrease in nitrite concentration from the millimolar concentrations ofthe in-vitro assay to the micromolar concentrations in the stomach reduces the reaction rate by a factor of 1000 for the side-chain nitrosation, whereas a million-fold reduction will be observed for nitrosation of the amino group.

T1 - Model risk analysis of nitrosatable compounds in the diet as precursors of potential endogenous carcinogens N2 - The potential health risk posed by the endogenous formation of N-nitroso compounds (NOC) from nitrosation of dietary ureas, guanidines, amides, amino acids and amanes (primary, secondary and aromatic) was estimated according to the model: Risk = ( daily intake of precursor] X (gastric concentration of nitrite ]n X [nitrosatability rate constant] X [cilrcinogenicity of derivative]. The daily intakes ofthese compound classes span five orders ofmagnitude (100 g/day amides, top; 1-10 mg/day secondary amines, ureas, bottom); the nitrosation rate constants span seven orders of magnitude (aryl amines, ureas, top; amides, secondary amines, bottom); and the carcinogenicity estimates span a 10 000-fold range from 'very strong' to 'virtually noncarcinogenic'. The resulting risk estimates likewise span an enormous range (nine orders of magnitude ): dietary ureas and aromatic amines combined with high nitrite concentration could pose as great a risk as the intake of preformed N-nitrosodimethylamine in the diet. In contrast, the risk posed by the in-vivo nitrosation of primary and secondary amines is probably negligible. The risk contributed by amides (including protein), guanidines and primary amino acids is intermediate between these two extremes.
