Phase II trial of gemcitabine in advanced non-small-cell lung cancer.

Gemcitabine has shown activity in different solid tumors. In the present study we have evaluated its efficacy in 32 patients with advanced non-small-cell lung cancer in a phase II trial. Gemcitabine (1250 mg/m2) was given intravenously as a 30-minute infusion on days 1, 8 and 15. Cycles were repeated every 4 weeks. Twenty-nine patients were evaluable for response and all patients for toxicity. Partial remissions and stable disease were seen in 4 (14%) and 13 (45%) patients, respectively. Improvement of symptoms occurred in 54% of the patients. Side effects were mild and included predominantly leukopenia and thrombocytopenia. In conclusion, gemcitabine is active and well tolerated in patients with advanced non-small-cell lung cancer.

On the efficient two-dimensional energy coding characteristics of spatial vision.

Recent evidence indicates that the vertebrate visual system possesses units whose receptive fields may be represented as narrow-band orientation and frequency specific filters. It has been indirectly demonstrated that equivalent psychophysical units act in such a way as to not discriminate the individual frequency components within each frequency band. Here we directly demonstrate this to be the case with digital images and so show an efficient energy code for spatial vision.
