    Notes: Abstract The applicability of the MINDO/3 method for the interpretation of the basicity of a series of substituted pyridines is critically discussed. Special attention is paid to the difference in thepK a -values of the two isomeric 4,6-diamino-2-methoxy-(2) and 2,4-diamino-6-methoxy-3-pyridine-carbonitrile (3) (2=2.01,3=4.17). Based on the concept of charge- and orbital-controlled reactions this difference can be explained readily.

    Notes: Abstract The colour of oxo- und pseudooxo croconic acid bisamides (1) in solution is due to two intense π → π* transitions in the visible region. These transitions are related to those of the Klessinger-Lüttke basic indigo chromophore. The first band corresponds to the second absorption band of this basic chromophore red-shifted by the intramolecular charge transfer excitation between the molecular subsystems of1. The second band of1 is closely related to the colour band of the basic indigo chromophore. According to the results of various analysis and projection techniques the interpretation of the colour of1 in terms of the basic indigo chromophore is superior to any other one in terms of alternative chromophoric subsystems.

    Notes: [Auszug] Like CFC-13B1, whose vertical distribution has already been measured6, CFC-12B1 has an anthropogenic origin: both substances are used as fire extinguishers. Their ultraviolet absorption characteristics are similar to those of the corresponding chlorine-containing species, but shifted towards longer ...

    Notes: [Auszug] IT HAS generally been held that early-type galaxies - lenticulars and ellipticals - are devoid of gas1. The gas lost by stars, both as the winds from red giants and as planetary nebulae, has been presumed to be blown out of the galaxies by the cumulative effect of supernova explosions. A galactic ...

    Description / Table of Contents: Résumé Cet article constitue un rapport préliminaire provenant du Groupe Oncologique du Sud-Ouest des Etats-Unis. Il concerne les effets obtenus par la chimiothérapie associée à l'exérèse du cancer du sein qui s'accompagne d'un envahissement des ganglions axillaires. L'étude est randomisée en fonction du paramètre “récepteur oestrogénique”. Les malades qui appartiennent au groupe “oestrogène récepteur négatif” sont soumis pendant 1 an ou 2 ans à une chimiothérapie CMFVP (cyclophosphamide, methotrexate, 5-FU, vincristine, prédnisone). Le groupe “oestrogène récepteur positif” est soumis à la même chimiothérapie pendant un an et/ou à un traitement hormonal. 1. Les malades du groupe “oestrogène récepteur positif” présentent une récidive plus tardive que celle des malades qui appartiennent au groupe “oestrogène récepteur négatif (p=0.004). 2. Il n'y a pas de différence significative en ce qui concerne ce fait pour les malades du groupe “oestrogène récepteur négatif qui sont traités un an ou deux ans par le CMFVP. 3. Les données pour les malades du groupe “oestrogène récepteur positif” sont trop récentes pour apprécier avec précision la durée de la survie totale ou celle de l'intervalle libre entre le traitement et la récidive. 4. La toxicité du traitement chimiothérapique est acceptable dès lors que le traitement est bien conduit sous une surveillance effectuée à intervalles réguliers et fréquents qui permet de dépister les signes avant-coureurs de la toxicité.
    Abstract: Resumen Este es un informe preliminar del Southwest Oncology Group de los Estados Unidos, grupo en el cual la terapia fue realizada en forma aleatorizada de acuerdo a los datos sobre receptores de estrógeno. Los pacientes con receptores de estrógeno negativos recibieron 1 o 2 años de CMFVP (ciclofosfamida, metotrexato, 5-fluorouracil, vincristina, y prednisona). Los pacientes con receptores de estrógeno positivos recibieron CMFVP por un año y/o terapia hormonal. 1. Los pacientes con receptores de estrógeno positivos presentaron un intervalo libre de enfermedad significativamente más largo que el de los pacientes con receptores de estrógeno negativos (p=0.004). 2. No se encontre una diferencia significativa en el intervalo libre de enfermedad entre los pacientes con receptores de estrógeno negativos que recibieron CMFVP por uno o por dos años. 3. Los datos sobre los pacientes con ER positivo son demasiado preliminares para poder informar sobre el estado libre de enfermedad o la supervivencia. 4. La toxicidad es aceptable en gracia a la monitoría mediante controles y exámenes frecuentes, lo cual resulta en una baja incidencia de toxicidad que pueda hacer peligrar la vida del paciente.
    Notes: Abstract This is a preliminary report of the Southwest Oncology Group in which therapy is randomized by estrogen receptor (ER) data. Estrogen receptor-negative patients receive either 1 or 2 years of cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone (CMFVP). The ER-positive group receive CMFVP for 1 year and/or hormonal therapy. The findings to date include: (a) Estrogen receptor-positive patients have a significantly longer disease-free interval compared to ER-negative patients (p =0.004); (b) there is no significant difference in diseasefree interval for ER-negative patients who receive either 1 or 2 years of CMFVP; (c) the data for ER-positive patients is too preliminary to report for disease-free or total survival; and (d) toxicity is acceptable because of frequent monitoring and examinations which result in the low percentage of life-threatening toxicity.

    Notes: Abstract The X-ray emission from the intracluster gas is a rich source of information on the metal abundance, evolution and mass profile of clusters. Methods for determining the mass of gas are reviewed; the total mass is uncertain. The best data so far available concentrate on the cluster core. Cooling flows are found within the cores of a significant fraction of rich and poor clusters, as well as in relatively isolated elliptical galaxies.

    Notes: Hyperfine coupling constants and g-factors determined by ESR and ENDOR spectroscopy are given for the radical anions of 21 syn-1,6:8,13-bridged [14]annulenes. The great majority of these values is reported for the first time. The hyperfine data are consistent with the single occupancy of an orbital which resembles a π-perimeter-LUMO of the same nodal properties. The sum of the coupling constants of the protons attached to the π-perimeter can be used as a planarity criterion for this perimeter.
