Beyond Empathy to System Change: Four Poems on Health by Bertolt Brecht.

Bertolt Brecht's poem "A Worker's Speech to a Doctor" is frequently cited as a means to raise awareness among health workers of the health effects of living and working conditions. Less cited is his Call to Arms trilogy of poems, which calls for class-based action to transform the capitalist economic system that sickens and kills so many. In this article, we show how "A Worker's Speech to a Doctor," with its plea for empathy for the ill, contrasts with the more activist and often militant tone of the Call to Arms trilogy: "Call to a Sick Communist," "The Sick Communist's Answer to the Comrades," and "Call to the Doctors and Nurses.

Effects of Residential Environmental Screening and Perception Surveys on Superfund Environmental Health Risk Perceptions.

Residents at one of the nation's largest and longest-operating Superfund sites (Butte, Montana) have expressed environmental health risk perceptions that often diverge from those of EPA and other official stakeholders responsible for the investigation and remediation of site contamination aimed at protecting human health and the environment. A random sample of Butte residents participated in a study of how home-based environmental screening influences environmental health perceptions. Participants completed surveys measuring environmental health perceptions before and after a home site screening of soil and drinking water for lead and arsenic conducted by the research team.

Environmental health perceptions in a superfund community.

A disconnect between community perceptions and officially documented Superfund remedial actions and health outcomes may hinder the essential community engagement at Superfund sites. This study evaluates the extent of one such potential disconnect in Butte, Montana, which is part of the largest U.S.

Studies on the blocking action of human Kv3.4 inactivation peptide variants in the mouse cloned Kv1.1 K+ channel.

1. Whole-cell patch clamp recordings were made from Chinese hamster ovary (CHO) cells stably expressing homomeric mouse Kv1.1 (delayed rectifier K+; mKv1.

Optimization of radioimmunotherapy using human malignant melanoma multicell spheroids as a model.

In vitro multicell spheroids from a human melanoma cell line and the human colon cancer cell line HT29, used as control, have been established as a model of poorly vascularized micrometastases in vivo. The antimelanoma monoclonal antibody 96.5 was radiolabeled with 131I at specific radioactivities from 1.

Surgery following chemotherapy and radiotherapy for advanced carcinoma of the cervix.

Ten patients with advanced squamous carcinoma of the cervix have been treated with both radiotherapy and monthly cyclical chemotherapy. All patients have subsequently undergone a simple hysterectomy and bilateral salpingo-oophorectomy with para-aortic and pelvic node biopsy. Six patients were found to be histologically free of disease, 2 patients had residual cervical disease completely excised, and 2 patients had persistent intra-abdominal disease.

Peripheral plasma immunoreactive 6-oxo-prostaglandin F1 alpha and gynaecological tumours.

Peripheral plasma levels of immunoreactive 6-oxo-PGF1 alpha, the stable hydrolysis product of prostacyclin, were significantly higher in female patients with tumours of the genital tract than in normal controls. In the groups with malignant tumours, these high levels declined after operation and/or radiotherapy if the tumour responded to treatment. In patients who did not respond to treatment or with tumour recurrence, levels of plasma 6-oxo-PGF1 alpha remained high or even rose further.

Closing volume and pregnancy.

Measurements of closing volume have been made in 20 women between the 36th and 40th weeks of pregnancy. The patients were studied in the erect and supine positions and the point of airway closure was related to functional residual capacity. The results show that airway closure occurred during tidal ventilation in 10 patients in the erect position and in six patients in the supine position.
