The low-lying excited states (La and Lb) of polyacenes from naphthalene to heptacene (N = 2-7) are studied using various time-dependent computational approaches. We perform high-level excited-state calculations using equation of motion coupled cluster with singles and doubles (EOMCCSD) and completely renormalized equation of motion coupled cluster with(More)
The objective of this study was to develop age- and gender-specific reference ranges for blood pressure in a large national database on blood pressure levels throughout childhood and adolescence in young Poles. A prospective cross-sectional study was performed in 2002−2005 in the representative sampling sites, selected randomly from the entire Poland.(More)
Following the nuclear accidents in Chernobyl and later in Fukushima, the nuclear community has been faced with important issues concerning how to search for and diagnose biological consequences of low-dose internal radiation contamination. Although after the Chernobyl accident an increase in childhood papillary thyroid cancer (PTC) was observed, it is still(More)
BACKGROUND To obtain current data on the occurrence ofwork-related symptoms of office computer users in Poland we implemented a questionnaire survey. Its goal was to assess the prevalence and intensity of symptoms of upper extremities, neck and back in office workers who use computers on a regular basis, and to find out if the occurrence of symptoms depends(More)
Native fluorescence (autofluorescence) of human tissues can be a valuable source of diagnostic information for detecting premalignant and malignant lesions in the human body. Digital imaging of autofluorescence may be useful for localization of such lesions during endoscopic examinations. Tissue fluorescence of 31 adenomatous polyps obtained from 16(More)
The objective of our study was to investigate whether digital imaging of autofluorescence could be applied in the detection of colonic malignancies. Autofluorescence was excited with a 325 nm line from a He-Cd laser. Images were recorded in vitro in six spectral bands. The material for study was 50 resected specimens for which images of 64 areas were(More)
The presented cross-sectional study, comprised a group of 1,130 children from 13-15 years of age living in Upper Silesia, Poland, was undertaken to ascertain the role of environmental factors in the development of adverse respiratory health outcomes. To estimate the prevalence of these effects, the ISAAC questionnaire supplemented by questions related to(More)
Granulocytes play a key role in the defence against bacterial infections. Their dysfunction may both predispose to and result from infections. The oxidative metabolism of peripheral blood granulocytes was studied in 50 children aged from 1 to 10 years, with recurrent upper respiratory tract infections and/or tonsillar hypertrophy. Four groups of patients(More)
OBJECTIVE A number of studies show an association between traffic-related air pollution and adverse respiratory health effects in children. However, most evidence relates to the regions with low or moderate levels of ambient air pollution. The study was undertaken to assess the impact of traffic-related air pollution on respiratory health status in children(More)
Two different methods to measure binocular longitudinal corneal apex movements were synchronously applied. High-speed videokeratoscopy at a sampling frequency of 15 Hz and a custom-designed ultrasound distance sensor at 100 Hz were used for the left and the right eye, respectively. Four healthy subjects participated in the study. Simultaneously, cardiac(More)
