    Notes: The factors responsible for the low transpiration rates of citrus were investigated. Leaf resistance to water vapor exchange by orange seedlings (Citrus sinensis L. cv. Koethen) including a substantial boundary layer resistance, was as low as 1 s cm−1 in humid air. Leaf resistance of well watered plants increased to values as large as 5 s cm−1 when the difference in absolute humidity between leaf and air was increased. Leaf resistance was only slightly influenced by temperature between 20 and 30°C providing the humidity difference between leaf and air was kept constant. Leaf resistance increased when leaf temperature was increased between 20 and 30°C when the absolute humidity external to the leaf was kept constant. Increased humidity differences resulted in greater increases in leaf resistance during initial experiments than when the experiments were repeated with the same leaves indicating acclimation by the plant. It was concluded that the effects of humidity differences on leaf resistance are partially responsible for the low transpiration rates of citrus.

    Leaf Water Potential Response to Transpiration by Citrus (1974)

    Notes: This paper reports on further studies of a model for interpreting leaf water potential data for Citrus. Experimental data confirmed the assumption that the ratio of vapor pressure deficit to leaf diffusion resistance adequately estimates transpiration when leaf-to-air temperature differences are small. Data collected diurnally indicated that the relationship between leaf water potential and transpiration followed a sequence of steady states without hysteresis. No difference in water transport characteristics was found for Valencia orange on three rootstocks in well-watered soil, but the two rootstocks Cleopatra mandarin and Rangpur gave slightly greater leaf water stress in Valencia orange leaves than‘Troyer’ citrange rootstock at high transpiration rates under mild soil water deficits. In laboratory studies, previously unstressed seedlings had higher leaf water potentials than field trees at equivalent transpiration rates. After several drying cycles, however, leaf water potentials were similar to those observed in the field.

    Notes: High and low self-esteem subjects received success or failure feedback regarding their performance on a task described as measuring their sensitivity to other people. Presumably as part of another study, changes in their self-perceptions regarding sensitivity to others were assessed, as well as changes in their performance on a different task Changes in self-perception were greater when the feedback was consistent with subjects' overall level of self-evaluation Task performance following failure was poorer than that following success HSE subjects performed better following success feedback, and LSE subjects performed more poorly following failure There were no significant performance changes for the HSE-failure and LSE-success subjects. The degree of change in self-perception of sensitivity to others was highly correlated with the magnitude of performance changes

    Notes: [Auszug] Our studies of the Fischer-Tropsch reduction have revealed that using cobalt/manganese oxide catalysts with a CorMn atomic ratio of 1.0 ±0.05 produces high yields of propene (C3H6) and low yields of methane. This selectivity has been attributed to Cl and C2 species on the catalyst surface1. ...

    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.

    Description / Table of Contents: Résumé Cette étude portant sur 5 ans montre que les résultats de la chimiothérapie par le CMFVP (cyclophosphamide, methotrexate, 5 FU, vincristine, prednisone) est supérieure à la chimiothérapie par le L-PAM (melphalan). La chimiothérapie associée pour traiter les malades atteints de cancer du sein opérable avec envahissement ganglionnaire donne un intervalle de temps entre l'opération et la reprise de l'affection, et une survie plus longues quand elle est assurée par le traitement continu avec les CMFVP par rapport au traitement discontinu avec le L-PAM. La diminution significative de la récidive et le prolongement de la survie sont manifestes pour la totalité du groupe traité par le protocole CMFVP et les sous-groupes suivants: femmes avant la ménopause, après la ménopause, avec envahissement ganglionnaire supérieur à 4 ganglions. Lorsque l'envahissement ganglionnaire concerne 1–3 ganglions, la récidive survient plus tardivement mais la durée de la survie au total n'est pas augmentée.
    Abstract: Resumen La presente actualización a 5 años continúa demostrando que la combinación CMFVP (ciclofosfamida, metotrexato, 5-fluorouracil, vincristina, y prednisona) es superior al L-PAM (melfalán). La quimioterapia adyuvante para pacientes con cáncer mamario operable con ganglios axilares positivos tratados con CMFVP continua demuestra un intervalo libre de enfermedad significativamente más prolongado y una mejor tasa de supervivencia total que la observada en pacientes tratados con regimenes intermitentes de L-PAM. Estos significativos descensos en la recurrencia y prolongación de la supervivencia pueden ser demostrados en la totalidad del grupo tratado con CMFVP y en los siguientes subgrupos: premenopáusico, postmenopáusico y mujeres con 4 o más ganglios axilares afectados. Las mujeres con 1–3 ganglios afectados exhibieron una supervivencia libre de enfermedad significativamente más prolongada, pero la ventaja en cuanto a supervivencia total no es estadísticamente significativa.
    Notes: Abstract This 5-year update of a study by the Southwest Oncology Group continues to show that combination chemotherapy utilizing cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone (CMFVP) is superior to melphalan (L-PAM) used alone. Adjuvant chemotherapy for patients with operable breast cancer and positive axillary nodes treated with continuous CMFVP confers a significantly longer disease-free and total survival compared to those treated with intermittent L-PAM. This significant decrease in recurrence and prolongation of survival are demonstrated for the entire CMFVP group and in the following subgroups: premenopausal, postmenopausal, and women with 4 or more axillary nodes. Women with 1 to 3 axillary nodes have a significantly longer disease-free interval, but a total survival advantage is not statistically significant.

    Notes: Summary The Southwest Oncology Group in a prospective randomized study compared one year of adjuvant combination chemotherapy with continuous CVFVP (cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone) to two years of intermittent L-phenylalanine mustard (L-PAM) in women with operable breast cancer with histologically positive axillary lymph nodes. In fully and partially evaluable patients with a 68-month median follow-up, treatment failures have occurred in 27% of 172 receiving CMFVP and 47% of 186 women given L-PAM (p = 0.002). The advantage for women receiving CMFVP was seen for all subsets regardless of menopausal status except among women who were premenopausal and had 1–3 positive nodes. Based on this study, a second study was implemented using both the estrogenreceptor (ER) content of the primary tumor and axillary nodal status to select therapy.
