El problema religioso en la primera década del siglo XX : "Clericalismo" y "Anticlericalismo" en la ciudad de València
1987
Con el presente artículo pretendo mostrar las principales características que la "cuestión religiosa" adopta en la sociedad española, y de un modo más específico en la valenciana, durante la primera década del siglo XX. Una vez presentadas las claves del enfrentamiento "clerical-anticlerical", nos detendremos en la Valencia de comienzos del siglo para conocer la dialéctica establecida entre la agrupación política "blasquista", decididamente anticlerical, y el conjunto de fuerzas militantemente católica que se opondrán a la primera.
Herbizide, 8. Mitt. Herbicides, VIII. Kernchlorierte und -bromierte Anilinoethentricarbonitrile
1987
In einer Reihe von Herbiziden tritt als gemeinsames Strukturelement die Nitrilgruppe auf, wie in 2,6-Dichlorbenzonitril oder 4-Amino-2,3,5,6-tetrafluorbenzonitril. Als ein weiterer Vertreter dieser Strukturklasse ist in unseren jungsten Untersuchungen das 2-Cyanamino-4,6-diethylpyrimidin durch seine herbizide Wirksamkeit aufgefallen. In Fortfuhrung dieser Forschungsrichtung und in Anlehnung an Herbizide, in denen Kernhalogenierungen eine dominierende Rolle spielen, sind nunmehr entsprechende Partialstrukturen in unsere Untersuchungen einbezogen worden.
Rates of uptake and metabolism of indole-3-acetic acid and 2,4-dichlorophenoxyacetic acid by cultured leaf segments at different stages of developmen…
1987
Immature leaf tissue of Triticum timopheevi Zukh. responded to supplied auxin and showed cell division in culture. The rates of uptake and of metabolism of indole-3-acetic acid and 2,4-dichlorophenoxyacetic acid by such tissues were measured and compared with those of mature auxin-unresponsive tissue. The purpose of these experiments was to determine whether or not the concentration of auxin in cultured mature tissue was a factor limiting the cell division response to auxin. The data indicate that neither alterations in rates of uptake nor alterations in rates of metabolism could explain the loss of responsiveness to auxin which apparently occurs during cell differentiation. The results are…
Neurosurgical Interventions for Intracranial Metastases
1987
In any neurosurgical material among the space-occupying neoplastic lesions in the brain there is an average frequency between 3 and 5% of deposits from malignant tumors of extracranial origin, i.e. metastases1,2,7. Definite regularities exist as regards the frequency with which particular tumors give rise to cerebral metastases and likewise as regards the incidence of solitary metastases (about 50% of cases), while in about a half of these patients we find several metastases. These lesions can involve the cerebral hemispheres, as well as the cerebellum and the brain stem26,28.
Hat die pelvine Lymphadenektomie im Rahmen der radikalen Zystektomie eine therapeutische Bedeutung?
1987
Bei mehr als 270 Zystektomien seit 1968 stellt die pelvine Lymphadenektomie seit 1973 einen integralen Bestandteil der radikalen Zystektomie an unserer Klinik dar. Wir beginnen die Lymphadenektomie mit der Dissektion der iliacalen Lymphknoten, nach cranial bis zur Aortenbifurkation. Sie wird zwischen V.iliaca und Muskulus psoas fortgesetzt, wo die sakrale Lymphknotengruppe entlang des proximalen Anteils des N. obturatorius ausgeraumt wird. Dem Verlauf dieses Nervs folgend, schliest sich die Ausraumung der Fossa obturatoria an, welche die Lymphadenektomie beendet.
Parasympathische Regulationsmechanismen am Herzen
1987
Die Tatigkeit des Herzens ist auf die spontane Erregungsbildung im Sinusknoten, die Fortleitung der Erregung und die Koppelung von Erregung und Kontraktion zuruckzufuhren (13). Diese primar im Herzen selbst gesteuerten Vorgange werden durch neurohumorale Faktoren beeinflust (7). Im Vordergrund steht hierbei das autonome Nervensystem, das mit seinen beiden Anteilen, dem Sympathicus und dem Parasympathieus, erregende bzw. dampfende Einflusse auf das Herz vermittelt. Die parasympathische Versorgung des Herzens erfolgt uber die nervi vagi und betrifft bevorzugt den Sinus- und AV- Knoten, die Vorhofe sowie die initialen Anteile des Reizleitungssystems, wahrend die Ventrikelmuskulatur weniger inn…
Distribution and chemotaxonomic significance of acetylenic fatty acids in mosses of the dicranales
1987
Abstract Thirty-eight moss species from four families of the order Dicranales were analysed for the fatty acid composition of their acyl lipids. In the Ditrichaceae and the Dicranaceae numerous species were found to contain acetylenic fatty acids in their triglycerides, 9,12,15-Octadecatrien-6-ynoic acid was the major component, often accounting for more than 80 mol%, whereas 9,12-octadecadien-6-ynoic acid was found in small amounts of less than 5 mol%. In some genera, all the species examined contained acetylenic fatty acids, e.g. Dicranella and Dicranum , whereas in the genus Campylopus all five species tested were free of acetylenic compounds. Two genera, Ditrichum and Dicranoweisia , we…
Properties of locust muscle 6-phosphofructokinase and their importance in the regulation of glycolytic flux during prolonged flight
1987
6-Phosphofructokinase (PFK, EC 2.7.1.11) from the flight muscle of the locust (Locusta migratoria) was purified to a specific activity of 80 μmol min−1 (mg protein)−1 (at 25°C). 1. The enzyme is made up from subunits ofMr-81600, and the smallest catalytically active form is likely to be a tetramer. 2. PFK activity is markedly affected by the pH of the assay; the optimum pH was at about 8. 3. Physiological concentrations of ATP strongly inhibit locust PFK by shifting the S0.5 for fructose 6-phosphate (concentration required for 50% of maximum activity) out of the physiological concentration range. At pH 7.4 and about physiological concentrations of ATP, the curve of PFK activity against the …
Einfluß von Steroidhormonen auf das Wachstum exokriner Pankreascarcinome. In vivo- und in vitro-Untersuchungen
1987
In jungerer Zeit wurde in der Literatur uber eine mogliche Bedeutung von Steroidhormonen (SH) fur das Wachstum ductaler menschlicher Pankreascarcinome (PaCa) mehrfach berichtet (1, 2, 3). Auch die Steroidhormonkonzentration i.S. von Pankreascarcinomtragern scheint verandert zu sein (4). Um weitere Information uber den moglichen Einflus von Steroidhormonen auf das Wachstum von Pankreascarcinomen zu bekommen, wurden in dieser Arbeit folgende Fragen untersucht: 1. Lassen sich Steroidhormon-Receptoren in normalem Pankreas, in Gewebe von Pankreascarcinomen sowie in Gewebe transplantierter Pankreascarcinome auf der Nacktmaus nachweisen? 2. Lassen sich unterschiedliche Steroidhormon-Konzentratione…

Myocardial Glutathione Alterations in Acute Coronary Occlusion in the Dog
1987
Glutathione (GSH) decreases in dog mycocardium upon acute coronary occlusion when compared with sham-operated dogs. Total glutathione content (GSHeq = GSH + ZGSSG) remains unchanged throughout the experiment (6 h after surgery) in both sham- and acute coronary occlusion-operated dogs. GSSG and GSH/GSSG ratio increases and decreases respectively in all animals but tends to reach the normal value after 6 h in sham-operated dogs. Both parameters (GSSG and GSH/GSSG ratio) remain altered in acute coronary occlusion-operated ones. This alteration of glutathione status in ischemic myocardium is discussed.

Surface Marker Analysis by Monoclonal Antibodies: A Valuable Technique in Childhood Acute Myeloid Leukemia
1987
A considerable number of monoclonal antibodies (MoAbs) with myeloid activity have been described during the last few years (summarized in [1]). These MoAbs have been applied to the study of normal myeloid differentiation, as well as to the surface marker analysis of acute myeloid leukemia (AML) [2–6]. Although there is a strong tendency for morphological differentiation to correspond to surface antigen differentiation of malignant myeloid cells [2, 3], a recent report has failed to correlate the FAB classification system with immunologic categories of AML [6].
Cycloaddition reactions. A new type of cycloadduct from a substituted 2-vinylthiophen and dmad
1987
Abstract Cycloaddition reactions between 2-(1-cyanoallyl)thiophen and the dienophiles diethyl azodicarboxylate, N-phenylmaleimide , methyl propiolate, and dimethyl acetylenedicarboxylate are reported. Products include simple benzo[b] thiophen carboxylates (13,19) and reduced derivatives (8,9,10,12,18), as a mixture of diastereoisomers, except in the adduct with diethyl azodicarboxylate. With dimethyl acetylenedicarboxylate a new type of tricyclic compound was also found (20).
Sur la dynamique des acquisitions à l'école élémentaire
1987
On the dynamics of learning in elementary schools. - The statistical results presented in this paper are based on data from a longitudinal survey of elementary school children in the Dijon area. They provide strong support for the hypothesis — which stresses the cumulative aspect of learning, predicting that better mastery of concepts and higher levels of initial learning are inputs which aid in further acquisition of learning — indicating that differences in learning in grade 1 that are attributable to pedagogical inputs exert a large and statistically significant effect on learning in grades 2 and 3.

Allgemeine Probleme der Globalsteuerung
1987
Sinkende Wachstumsraten bei gleichzeitig hoher Arbeitslosigkeit und drohender Inflationsgefahr signalisieren seit Mitte der 70er Jahre, das die antizyklische Globalsteuerung mit Mangeln behaftet ist, die der erhofften Verstetigung des Konjunkturverlaufs entgegenstehen. Die „antizyklische„ Wirtschaftspolitik wird sogar oft als Ursache fur die Instabilitat des Wirtschaftsablaufs genannt. Aus der Praxis der Stabilisierungspolitik aller Industrielander wird deutlich, das die nominellen Staatsausgaben kaum wirksam antizyklisch eingesetzt wurden. Selten sind die Ziele des § 1 StWG auch nur annahernd erreicht worden. Neben den staatlichen Organen wird auch den Sozialpartnern haufig ein Teil der Sc…

INFLUENCE OF RECOMBINANT PRO-UROKINASE ON THE HEMOSTATIC SYSTEM IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION
1987
Recombinant unglycosylated pro-urokinase (recombinant single chain urokinase-type plasminogen activator, CG4509) was given to twelve patients (pts.) with acute myocardial infarction as a 20 mg bolus followed by a 60 mg intravenous infusion (iv.inf.) over 1 hour and to twelve pts. as a 10 mg bolus followed by a 30 mg iv.inf. over 1 hour. Reperfusion was angiographically confirmed in 9/12 pts. with the higher dose and in 6/12 pts. who obtained the lower dose. Different parameters of hemostasis were determined before administration, 30 min after the beginning of inf.,at the end of inf., 60 min thereafter and 6-12 hours afterwards .The most significant systemic changes were observed 60 min afte…
The Role of Striated Sphincter Muscle in Urethral Closure Under Stress Conditions: An Experimental Study
1987
Decisive for urethral closure under stress is an increase in intraurethral pressure. This pressure increase is significantly affected by urethral tonus, passive pressure transmission and reflex pressure transmission. Approximately half of the urethral tonus is produced by the striated sphincter muscles (Rud et al. 1981; Tanagho 1979).
Changes of Angiotensin Converting Enzyme (Ace) Levels During Activation of the Renin-Angiotensin-Aldosterone System (RAAs)
1987
The aim of this study was to evaluate the changes of ACE levels during RAAs activation induced by: 1) a continuous graded bicycle ergometer test performed in a group of 15 males health youths aged between 21 and 30 years, with average age of 25.8 +/- 2.85 years; 2) i.m. injection of 20 mg of frusemide in 11 health youths (10 males and 1 female), aged between 20 and 30 years, with average age of 24.09 +/- 2.77 years; 3) dialytic treatment in 25 patients (12 males and 13 females), suffering from chronic renal failure, aged between 26 and 68 years, with average age of 54 +/- 15.42 years. Plasmatic renin activity (PRA), aldosterone (ALD) and ACE levels were determined by RIA in basal conditions…
Zinc accumulation in the telencephalon of lizards.
1987
The zinc concentration in the brains of two species of lizard was determined by atomic-absorption spectrophotometry. The zinc concentration was found to be highest in the telencephalon of Lacerta galloti (21.1 micrograms/g fresh weight) and Podarcis hispanica (16.77 +/- 0.8 micrograms/g) while the mesencephalon and brain stem exhibited lower zinc concentrations, i.e., 7.0 micrograms/g in Lacerta galloti and 6.08 +/- 0.4 micrograms/g in Podarcis hispanica. This high telencephalic concentration of zinc is paralleled by intense and well-defined Timm reactivity used for demonstrating the presence of zinc-containing boutons at the light-microscope level. Volumetric-densitometric studies of these…

El monumento romano de la Ermita de la Virgen del Cid (La Iglesuela del Cid, Teruel)
1987
La existencia de restos arquitectónicos de tipo monumental en la. ermita de la Virgen del Cid ya fue señalada por J. Salvador en 1890. Posteriormente A. Ventura, en 1975, apuntó su posible pertenencia a un mausoleo funerario de época romana. Por último, el autor de estas líneas realizó un primer estudio de estos restos en 1983, en el contexto de un trabajo general sobre el yacimiento arqueológico de El Morró del Cid.

Test Procedures in Configural Frequency Analysis (CFA) Controlling the Local and Multiple Level
1987
The test statistics used until now in the CFA have been developed under the assumption of the overall hypothesis of total independence. Therefore, the multiple test procedures based on these statistics are really only different tests of the overall hypothesis. If one likes to test a special cell hypothesis, one should only assume that this hypothesis is true and not the whole overall hypothesis. Such cell tests can then be used as elements of a multiple test procedure. In this paper it is shown that the usual test procedures can be very anticonservative (except of the two-dimensional, and, for some procedures, the three-dimensional case), and corrected test procedures are developed. Further…
