- Anxiety and depression are dimensions of emotional state that can be validly assessed with self-report measures. This article introduces a new self-report questionnaire for depression and anxiety (Emotional State Questionnaire (EST-Q)) and presents data on its reliability and validity. The items of the EST-Q were derived from diagnostic criteria of DSM-IV and ICD-10. Thirty-three items were rated on a five-point frequency scale. The questionnaire was administered to 194 inpatients with depressive and anxiety disorders and to a population sample of 479 subjects. According to the results of factor analysis, five subscales were formed: Depression, Anxiety, Agoraphobia-Panic, Fatigue, and Insomnia. EST-Q and subscales showed acceptable internal consistency (alpha = 0.69-0.88). Significant differences in subscales between patients and population and across diagnostic groups confirmed the discriminant validity of the instrument. Depression, Anxiety, and Agoraphobia-Panic subscales distinguished corresponding diagnostic groups. Fatigue and Insomnia appeared to assess nonspecific psychopathology dimensions characteristic of several psychiatric disorders.

- The influence of hypothermia (2 degrees, 15 degrees and 28 degrees C) upon the effect of X-irradiation on chromatin from human diploid fibroblast cells (AG1518) was studied using the fluorescent halo assay. Rewinding of supercoils was inhibited in a dose-dependent manner when cells were irradiated with 4, 8 or 16 Gy. This inhibition of rewinding was reduced when cells were irradiated at subnormal temperatures compared with cells irradiated at 37 degrees C. One hour's preincubation at low temperature did not influence rewinding. When AG1518 cells were irradiated at 37 degrees C in the presence of the radical scavenger DMSO (0.5 M), the radiation-induced damage was reduced. No additional protection of DMSO in hypothermic cells (2 degrees C) was found, possibly indicating that OH-radical-mediated effects are more temperature dependent. These results are similar to those recently found for the malignant MCF-7 cell line.
