The effect of the target size on the detecton of luminance and chromaticity flicker and gratings was studied. Discrimination ellipses in a luminance-chromaticity plane were determined with square test areas subtending from 1/4 degree to 1 degree. Pure luminance modulation thresholds and pure chromaticity modualtion thresholds were obtained from square(More)
AIM To investigate whether breast cancer patients' visits to an outpatient clinic for late outcome (OCLO) can be replaced by patient reported outcome measures (PROMs), by comparing late toxicity scored at the OCLO with PROMs. METHODS All breast cancer patients treated in our institute with adjuvant radiotherapy 10-11years ago were invited to visit the(More)
A gene encoding a putrescine oxidase (PuORh, EC 1.4.3.10) was identified from the genome of Rhodococcus erythropolis NCIMB 11540. The gene was cloned in the pBAD vector and overexpressed at high levels in Escherichia coli. The purified enzyme was shown to be a soluble dimeric flavoprotein consisting of subunits of 50 kDa and contains non-covalently bound(More)
