Urticaria, Abdominalschmerzen, Arthritis, Pseudotumor cerebri und nephrotisches Syndrom bei 20jähriger Patientin
1988
Mit 19 Jahren wurde die iranisch-deutsche Patientin im Oktober 1984 wegen einer Coombs-positiven hamolytischen Anamie behandelt. IgG-typische, nichtspezifische Antikorper wurden nachgewiesen. Zuvor war wegen eines grippalen Infektes ein Kombinationsmedikament verordnet worden, das Brompheniramin, Kalziumascorbat, Prophyphenazon, Salizylamid, Chini-din-Hydrochlorid und Coffein (Ilvico®) enthielt. Spezifische Antikorper gegen diese Substanzen waren nicht gesucht worden. Der Coombs-Test blieb 5 Monate positiv. Eine Corticoid-Therapie wurde mit Erfolg klinisch begonnen, von der Patientin wahrscheinlich jedoch nicht konsequent fortgesetzt. Antinukleare Antikorper waren nicht nachweisbar.
The Diagnosis of Disease by Element Analysis
1988
The elemental composition of the human body images in principle the elements of the periodic system. In the literature, about 80 elements are reported to occur in the human body and the number is expected to increase by the introduction of methods more sensitive in detection. The elemental composition in reference man as published (1) is summarized in tab. 1. From the major elements in reference man, the determination of the elements nitrogen, calcium, phosphorus, potassium, sodium, chlorine and magnesium are of importance for the diagnosis of diseases. The importance of the element determination for the diagnosis of diseases is also documented by the numbers of element determinations done …
Changes of Hemodynamic Parameters, Pulmonary Gas Exchange, and Extravascular Lung Water During Esophageal Cancer Surgery
1988
Esophagectomy is often connected to postoperative pulmonary complications with a high mortality rate [1, 3,4]. From 1980 to 1985 we treated 19 patients after esophagectomy in our intensive care unit. Nine patients (47%) died of pulmonary complications. From the literature [3] and from our own observations we came to the conclusion that the first pulmonary changes start during the operative procedure.
The singular fate of Genetics in the History of French Biology, 1900-1940
1988
In this study we have examined the reception of Mendelism in France from 1900 to 1940, and the place of some of the extra-Mendelian traditions of research that contributed to the development of genetics in France after World War II. Our major findings are: (1) Mendelism was widely disseminated in France and thoroughly understood by many French biologists from 1900 on. With the notable exception of Lucien Cuenot, however, there were few fundamental contributions to the Mendelian tradition, and virtually none from about 1915 to the midthirties. Prior to 1900, Cuenot's work was already marked by a striking interest in physiological mechanisms; his physiological preoccupations played a consider…
New adsorbents for thymidylate synthase affinity chromatography
1988
New affinity adsorbents, intended for chromatography of thymidylate synthase (EC 2.1.1.45) from different sources, consisting of p-[N-[(2-amino-4-hydroxy-6-quinazolinyl)-methyl]-N-2-propynylamino]benzoyl-γ-[α-(3-carboxypropylamino)]glutamyl-glutamyl immobilized either on macroporous copolymer of acrylonitrile and n-butyl acrylate or on macroporous polymer of acrylonitrile itself, both crosslinked with divinylbenzene and having aminoethyl groups, were obtained. Both adsorbents were found to be effective in dUMP-dependent binding of thymidylate synthase from regenerating rat liver.

Aim of the paper is to show a computational paradigm, that reduces some algorithms on undirected graphs into image analysis algorithms. In particular two parallel algorithms on undirected weighted graphs, often used in the analysis of sparse images, are described.
Single-Particle Excitations and Collective Vibrational Modes in 96Zr
1988
New results from (n,n’γ) and (p,p’γ) reactions, as well as from β- decay confirm the double subshell closure in 96Zr and provide a detailed level scheme for this nucleus. The 1750 keV first 2+ state is described as a neutron particle-hole excitation, while the positive-parity band built on the 1582 keV excited 0+ state is characterised by quadrupole vibrational collectivity at low spins. Candidates for two-phonon octupole, quadrupole-octupole and higher multipole states are suggested on the basis of fast El and E2 decays to the 3- octupole state. The recently observed large octupole strength, its inverse relationship with the filling of the νlh11/2 orbital, and the onset of quadrupole defor…

Therapeutische Alternativen beim fortgeschrittenen Nierentumor
1988
Metastasierte Nieren-Carcinome stellen ein ungelostes therapeutisches Problem dar. Seit uber 20 Jahren werden in die Immuntherapie immer wieder Erwartungen gesetzt, die sich letztlich nicht erfullt haben. Die Liste immunologischer Therapieansatze ist lang und reicht von der BCG-Therapie bis zu den verschiedenen Interferonen. Damit konnten zwar in wenigen Fallen komplette Metastasenregressionen erzielt werden. Ein therapeutischer Durchbruch war es jedoch nicht.

A Theory of electrical circuits with resistively coupled distributed structures : Delay time predicting
1988
This paper deals with qualitative properties ( existence, uniqueness, and especially, stability) and numerical solution of a circuit consisting of a resistive multiport with r-c-g "exactly modeled" distributed elements connected to its terminals. This kind of results are useful, for instance, when we study the effect of interconnections on the speed of transient process from an integrated structure. A formula to evaluate the delay time as a global parameter of the circuit is given and verified by numerical calculus. peerReviewed

Statistische Methoden für die Analytik Grundlagen und praktische Anwendungen
1987
Im Laufe ihrer langen Geschichte hat die Chemie zum besseren Verstandnis und zur genaueren Beschreibung experimentell beobachteter Phanomene zunehmend kompliziertere mathematische Formalismen herangezogen und auch mitentwickelt — man denke zum Beispiel an Thermodynamik, die Kinetik und die Quantenchemie. Mit den Angaben von Mittelwerten und Standardabweichungen als Mittel etwa zur zusammenfassenden Angabe einer Reihe von Mesergebnissen hat sie auch Hilfsmittel der Statistik benutzt. Aber erst die Entwicklung der modernen analytischen Chemie zu einem betont quantitativen Zweig der Chemie, der obendrein uber die angewandten Nachweismethoden heute in hohem Mase physikalisch durchdrungen ist, h…

ChemInform Abstract: Theoretical and Spectroscopic Studies on Imino-Carbon Palladated Pyridine-2-carbaldimines.
1987
Abstract Ab initio LCAO-MO-SCF calculations on the model compounds C 5 H 4 N-2-C(R 1 )=NH [R 1 = H ( 2c ) and R 1 = trans -PdCl(PH 3 ) 2 ( 4c )] indicate that the E - trans conformation is favored over the E - cis one by 16.9 kJ mol −1 for 2c and by 25.0 kJ mol −1 for 4c . One of the factors which stabilizes the E-trans arrangement for 4c is a weak bonding interaction between the palladium center and the pyridine nitrogen. On going from 2c to 4c a slight charge enrichment on the pyridine carbons and a more pronounced one on the nitrogen atoms is computed, whereas the charge density of the imino carbon atom is decreased. In 4c no π contribution to the PdC bond is observed. Protonation of th…
Correlation coefficients in human skulls: Significant sexual differences
1987
This study of 500 male and female skulls proves: significant differences of correlation coefficients (p less than or equal to 0.01) occur between the two sexes. The combined variables are: 1. bizygomatic breadth (45)/skull base length (5) 2. bizygomatic breadth (45)/foramen magnum length (7) 3. bizygomatic breadth (45)/foramen magnum breadth (16) 4. bizygomatic breadth (45)/basion-bregma height (17) 5. foramen magnum breadth (16)/skull base length (5) Female skulls have generally higher correlation coefficients values than males which is interpreted as an indication of homogeneous growth.

Einführung einer Dreifachbindung in das Bicyclo[6.1.0]nonan-Gerüst
1987
Ausgehend von den auf verschiedenen Wegen zuganglichen Ketonen 1a–c wird die Einfuhrung einer Dreifachbindung in das Bicyclo[6.1.0]nonan-Gerust mit Hilfe der Selenadiazol-Methode untersucht. Dabei Konnen die hochgespannten Bicyclo-[6.1.0]nonine 2a und 2b in reiner Form isoliert werden. Masgeblich fur die Position der Dreifachbindung ist die Regioselektivitat der Ringschlusreaktion bei der Selenadiazolbildung. Introduction of a Triple Bond into the Bicyclo[6.1.0]nonane Skeleton The introduction of a triple bond into the bicyclo[6.1.0]nonane skeleton is investigated by applying the selenadiazole method to the ketones 1a–c, accessible on different pathways.

Precision Spectroscopy on Trapped Radioactive Ions: Ground-State Hyperfine Splittings of 133 Ba + and 131 Ba +
1987
The ground-state hyperfine splitting of radioactive Ba+ isotopes of mass 133 and 131, confined in a r.f. quadrupole trap, has been measured by laser-microwave double resonances. The results are Δν(133) = 9 925 453 554.59(10) Hz and Δν(131) = 9 107 913 698.97 (50) Hz. The experiment, including measurements of systematic shifts, was performed on quantities of about 1012 isotopes, produced by nuclear reactions and collected at the ISOLDE facility at CERN. The precision is comparable to equivalent measurements on stable isotopes and demonstrates the high-sensitivity of the stored-ion technique. The experiment can be regarded as a first step to a systematic precision study of hyperfine anomalies…
Pyridinedicarboxylates, the first mechanism-derived inhibitors for prolyl 4-hydroxylase, selectively suppress cellular hydroxyprolyl biosynthesis. De…
1987
Two pyridinedicarboxylates, predicted [Hanauske-Abel (1983) M.D.-Ph.D. Thesis, Philipps Universität Marburg] and later found to be potent reversible inhibitors of purified prolyl 4-hydroxylase [Majaama, Hanauske-Abel, Günzler & Kivirikko (1984) Eur. J. Biochem. 138, 239-245] were investigated with respect to their effect on hydroxyprolyl biosynthesis in the fibroblast/collagen and the macrophage/Clq systems, and the effect was compared with that of the iron chelator 2,2′-dipyridyl, the compound usually employed to inhibit cellular hydroxyprolyl formation. Only the enzyme-mechanism-derived pyridinedicarboxylates were highly selective inhibitors, and only they lacked overt cytotoxicity. M…
Structure and function of ferredoxin-NADP+-oxidoreductase
1987
The redox-enzyme ferredoxin-NADP-oxidoreductase has been shown to be activated by light and inactivated in the dark. This review will summarize recent data concerning the biochemical characterization of the enzyme compared to its in-vivo activation. Further-more the mechanism of this activation process is discussed as a conformational change caused by the light-driven proton gradient.
Capillary column gas chromatographic identification of sugars in honey as trimethylsilyl derivatives.
1987
A method for identifying carbohydrates (mono-, di- and trisaccharides) in honey is presented. It is based on the separate preparation of both trimethylsilyl ethers and oxime trimethylsilyl ethers of the sugars followed by their gas chromatographic separation on a fused-silica capillary column coated with OV-101 using temperature programming. From the two chromatograms, the number of peaks given by each derivatized sugar, their relative retention times and peak-area ratios are used for identification. The identities of two unidentified trisaccharide peaks are considered. Quantitative applications to honey sugar analysis are discussed.
