[21] Assay of blood glutathione oxidation during physical exercise

1995

Publisher Summary This chapter describes a method to accurately measure glutathione (GSH) and glutathione disulfide (GSSG) in the blood of humans and animals that perform physical exercise. With this method, it is possible to assess the oxidative stress associated with physical exercise by measuring changes in the blood GSH/GSSG ratio. Glutathione measurement is performed by a modification of the glutathione S -transferase method of Brigelius et al. This is based on the conjugation of chlorodinitrobenzene with GSH catalyzed by glutathione S -transferase. The adduct formed, S-(2,4-dinitrophenyl)glutathione, exhibits a maximum of absorbance at 340 nm. The precipitation of proteins is carried …

Cellular Acetylcholine Receptor Expression in the Brain of Patients with Alzheimer’s and Parkinson’s Dementia

1995

Binding studies and receptor autoradiography reveal the overall changes of acetylcholine receptors (AChR) in Alzheimer’s and Parkinson’s dementia cortices.2,5 A detailed account of these changes requires a study of neurochemical phenotype of individual neurons as basic elements of networks constituting the substrate of cortical functions.4 Examples will be given for cell-type specific AChR localization in normal and diseased human cerebral cortex.

Error detecting in inductive inference

1995

Several well-known inductive inference strategies change the actual hypothesis only when they discover that it “provably misclassifies” an example seen so far. This notion is made mathematically precise and its general power is characterized. In spite of its strength it is shown that this approach is not of universal power. Consequently, then hypotheses are considered which “unprovably misclassify” examples and the properties of this approach are studied. Among others it turns out that this type is of the same power as monotonic identification. Then it is shown that universal power can be achieved only when an unbounded number of alternations of these dual types of hypotheses is allowed. Fi…

Trace determination of 90Sr and 89Sr in environmental samples by collinear resonance ionization spectroscopy

1995

Collinear resonance ionization spectroscopy has been developed as a sensitive technique for fast trace detection of 90Sr and 89Sr in the environment. A detection limit for 90Sr of 107 atoms in the presence of 1017 atoms in the presence of 1017 atoms of stable Strontium has been achieved, while the applicability of the method has been demonstrated on real world samples. After collection and chemical separation, strontium is surface ionized, accelerated to 33keV and mass separated. The ions are neutralized and the emerging fast atoms interact with an argon ion laser beam (γ=364 nm) in a quasi‐collinear geometry. Optical excitation starts from the long‐lived 5s4d3 D2 state of strontium, which …

Datenschutz in Krankenhausinformationssystemen

1995

Medizinische Daten gehoren zu den besonders sensitiven Daten einer Person. Sie unterliegen der arztlichen Schweigepflicht und dem Recht auf informationelle Selbstbestimmung. Durch die Einfuhrung von Informations- und Kommunikationstechnologie soll die Qualitat und Effizienz der Gesundheitsversorgung, besonders im Krankenhaus, verbessert werden. Dadurch entstehen aber auch neue Risiken fur die Vertraulichkeit der medizinischen Daten. Bestehende Krankenhausinformations-, Abteilungs- und Arbeitsplatzsysteme lassen diese Risiken weitgehend auser Acht. Die existierenden technischen Konzepte fur die Verlaslichkeit und Vertrauenswurdigkeit medizinischer Informationssysteme mussen daher so bald wie…

Existentially Closed Groups in Specific Classes

1995

This survey article is intended to make the reader familiar with the algebraic structure of existentially closed groups in specific group classes, and with the ideas and methods involved in this area of group theory. We shall try to give a fairly complete account of the theory, but there will be a certain emphasis on classes of nilpotent groups, locally finite groups, and extensions.

Chemical and enzymatic synthesis of glycopeptides

1995

Progress recently made in the synthesis of biologically relevant N- and O-glycopeptides is illustrated by examples. In this context, developments in the preparation of complex saccharide side chains and in the subsequent coupling to peptide portions is described. Special emphasis is given to the synthesis of Lewis antigen-type structures. Furthermore, modern methods in solid phase peptide syntheses utilizing glycosylated building blocks are presented. Recent advances in glycopeptide syntheses employing enzymatic methods in deprotection steps as well as in peptide/saccharide chain elongation are reported.

Explaining the process of change taking place in legal rules and social norms: The cases of institutional economics and new institutional economics

1995

This paper deals with the phenomenon of institutional change and has been conceived as an attempt to answer the following question: Can we retain theimage of institutional change contained in a theory when we replace a methodological foundation on which the theory was built by a different and alternative one? For an answer to be developed, special attention is paid to the contributions made by institutional economists (IE) and those made by transaction cost—new institutional economists (NIE). The question clearly shows that it is a paper on applied methodology rather than a survey on institutional change contributions. Because of that, its main purpose is not to increase our knowledge about…

Estimating feature discriminant power in decision tree classifiers

1995

Feature Selection is an important phase in pattern recognition system design. Even though there are well established algorithms that are generally applicable, the requirement of using certain type of criteria for some practical problems makes most of the resulting methods highly inefficient. In this work, a method is proposed to rank a given set of features in the particular case of Decision Tree classifiers, using the same information generated while constructing the tree. The preliminary results obtained with both synthetic and real data confirm that the performance is comparable to that of sequential methods with much less computation.

Logics for context-free languages

1995

We define matchings, and show that they capture the essence of context-freeness. More precisely, we show that the class of context-free languages coincides with the class of those sets of strings which can be defined by sentences of the form ∃ bϕ, where ϕ is first order, b is a binary predicate symbol, and the range of the second order quantifier is restricted to the class of matchings. Several variations and extensions are discussed.

Knowledge representation for robotic vision based on conceptual spaces and attentive mechanisms

1995

A new cognitive architecture for artificial vision is proposed. The architecture is aimed for an autonomous intelligent system, as several cognitive hypotheses have been postulated as guidelines for its design. The design is based on a conceptual representation level between the subsymbolic level processing the sensory data, and the linguistic level describing scenes by means of a high-level language. The architecture is also based on the active role of a focus of attention mechanism in the link between the conceptual and the linguistic level. The link between the conceptual level and the linguistic level is modelled as a time-delay attractor neural network.

Cuticular protein genes in Tenebrio molitor (Coleoptera: Tenebrionidae)

1995

1210-5759; We have previously isolated from the beetle Tenebrio molitor, cDNAs coding for two glycine-rich cuticular proteins named ACP-20, ACP-22 and ACP-17 and an alanin-rich cuticular protein named LPCP-22. The ACP-20, ACP-22, ACP-17 mRNAs are detected by Northern blot and In situ hybridization analysis only in epidermal regions secreting heavily sclerotized cuticle during the pharate adult stage.The LPCP-22 mRNA is detected in most epidermal regions during the secretion of larval and pupal cuticles. Then, its presence is restricted to the epidermal zones secreting intersegmental soft cuticle in the newly ecdysed pupa. The stage- and tissue-specific gene system seems to be convenient mod…

Una nueva mirada al informe de Ley Agraria de Jovellanos doscientos años después

1995

Editada en la Fundación Empresa Pública Con motivo del bicentenario (1795-1995) de la publicación de lnforme de Ley Agraria de Jovellanos se presenta una visión retrospectiva de esa obra ya clásica del pensamiento español incluyendo un repaso de sus múltiples y desacordes intérpretes modernos y un análisis del interior del texto e incluso del título. Se concluye insistiendo en la plena inserción del Informe en la tradición ilustrada española, en que los usuales calificativos de mercantilista, liberal smithniano o fisiócrata son inadecuados y en que es preciso restituir la obra y su autor a su tiempo.

Collisional Raman Linewidths of Nitrogen at High-Temperature (1700-2400 K)

1995

0146-9592; New high-temperature measurements of collisional linewidths of the Roman Q branch of nitrogen have been performed at 1700-2400 K with stimulated Raman spectroscopy in a tungsten filament. We fitted these data together with previous data obtained in the 295-1500-K range to redetermine the parameters of the relaxation models used in coherent anti-Stokes Raman spectroscopy thermometry. The improvement in the accuracy of the temperature measurement has been checked. Semiclassical calculations of linewidths in the 1700-2400-K range agree with the experimental data and have been extended to even higher temperatures.

Polytopiekriterien in der Diagnostik von Hirnstammläsionen

1995

Bei Patienten mit akuten klinischen Zeichen einer Hirnstammlasion, versuchen wir fur gewohnlich, die Symptome und klinischen Befunde einer einzigen Lokalisation zuzuordnen. Aber selbst in dem anatomisch sehr komplex aufgebauten Hirnstamm kann eine unifokale Lasion nicht in jedem Fall alle neurologischen Ausfalle erklaren. Es mus dann von mehreren kleinen Lasionen innerhalb des Hirnstamms ausgegangen werden.

Diminished Inhibition of Adhesion Molecule Expression in Prostacyclin Receptor Desensitized Human Platelets

1995

Long-term exposure of platelets to prostacyclin or iloprost (100nM, 3hr) results in receptor desensitization measured as decrease in 3H-iloprost binding sites by 47 +/- 14%. Desensitized platelets respond with an increased adhesion to endothelial cells. The mechanism of increased adhesiveness was studied by measuring the expression of the adhesion molecule CD62p (p-selectin; GMP140) on washed human platelets by flowcytometry. In thrombin stimulated platelets CD62p expression was dose-dependently reduced by iloprost. In receptor desensitized platelets IC50 for iloprost inhibition of thrombin-induced CD62p expression increased from 0.48 +/- 0.10 to 2.4 +/- 0.7 nM.
