Es werden verschiedene Anforderungen an die menschliche Informationsverarbeitung betrachtet, und es wird jeweils gefragt, welche Eigenschaften die Wissensrepr{\"a}sentation haben muß, um diesen Anforderungen zu gen{\"u}gen. Im einzelnen werden die Objektwahrnehmung, die anschauliche Vorstellungst{\"a}tigkeit, die Aufmerksamkeitssteuerung, die Erkennung semantischer Relationen, die Handlungskontrolle und der Erwerb von Wortbedeutungen betrachtet. Es wird die Schlußfolgerung gezogen, daß eine Repr{\"a}sentation in diskreten symbolischen Einheiten der Dynamik der Wissensnutzung unter den verschiedenen Anforderungen wenig gerecht wird. Es scheint naheliegender, Wissen direkt in Handlungseinheiten zu repr{\"a}sentieren. Solche Einheiten sollten Informationen {\"u}ber einzelne Handlungen mit Informationen {\"u}ber Situationskontexte verbinden, in denen die Handlungen erfolgreich verwendet worden sind.

To date at least one of the probes has been found to be informative in each species. The human genome, however, has been the major target of many fingerprintins studies. Using the probe (CAC)5 or (GTG)5, individualization of all humans is possible except for monozygotic twins. Paternity analyses are now perfonned on a routine basis by the use of multilocus fingerprints, inctuding also cases of deficiency, i.e. where one of the parents is not available for analysis. In forensie science stain analysis is feasible in all tissue remains containing nuc)eated cells. Depending on the degree of DNA degradation a variety of oligonucleotides are informative, and they have been proven useful in actual case work. Advantages in comparison to other methods including enzymatic DNA amplification techniques (PCR) are evident. Fingerprint patterns of tumors may be changed due to the gain or loss of chromosomes and/or intrachromosomal deletion and amplification events. Locus-specific probes were isolated from the human (CAC)5/( GTG)5 fingerprint with a varying degree of informativeness (monomorphic versus truly hypervariable markers). The feasibility of three different approaches. for the isolation of hypervariable mono-locus probes was evaluated. Finally, one particular mixed simple (gt)n(ga)m repeat locus in the second intron of the HLA-DRB genes has been scrutinized to allow comparison of the extent of exon-encoded (protein-) polymorphisms versus intronie bypervariability of simple repeats: adjacent to a single gene sequence (e.g. HLA-DRB1*0401) many different length alleles were found. Group-specific structures of basic repeats were identified within the evolutionarily related DRB alleles. As a further application it is suggested here that due to the ubiquitous interspersion of their targets, short probes for simple repeat sequences are especially useful tools for ordering genomic cosmid, yeast artificial chromosome and phage banks.}, subject = {DNS}, language = {en} } @incollection{ShephardMeierLutz1991, author = {Shephard, S.

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.}, subject = {Aminos{\"a}uren}, language = {en} } @incollection{CantoreggiGuptaLutz1993, author = {Cantoreggi, S. and Gupta, R.

Nuclease P 1-enriched adducts were 32P-labelled and purified by high-salt ( 4.0 M ammonium formate, pH 6.1} C1s reverse-phase TLC. After elution from the layer with 2-butoxyethanol:H20 (4:6), adducts were separated by two-dimensional PEI cellulose TLC in non-urea solvents (2.0 M ammonium formate, pH 3.5, and 2.7 M sodium phosphate, pH 5.6). One major, three minor and several trace adducts were detected. The efficiency of the kinase reaction depended on the ATP concentration. Use of standard labelling conditions (['Y· 32P]ATP, <3000 Ci/mmol; <2 Mikromol) resulted in poor ( 4-7\%) adduct recovery. An ATP concentration of 40 Mikromol, however, increased the labeJling efficiency by a factor of 5-8 (35-55\% based on 3H-SO labelied DNA). The results indicate that the new separation technique is suitable for the relatively polar SO-DNA adducts and that high labelling efficiency can be achieved.}, subject = {Medizin}, language = {en} } @incollection{Krueger1990, author = {Kr{\"u}ger, Hans-Peter}, title = {The driver under the influence of passenger and alcohol}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-86275}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1990}, abstract = {No abstract available.}, subject = {Kraftfahrer}, language = {en} } @incollection{LohseKlotzSchwabeetal.1988, author = {Lohse, M.

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.
