BACKGROUND Fractal dimensions always involve some averaging with respect to the given geometrical object. The classical geometrical description includes overly detailed geometrical information, rendering the precise formulation of equations ineffective. The problems associated with the functionality and growth of biological systems according to their(More)
Aronia melanocarpa is a common plant in Eastern Europe and in the North America. The fruit contains a lot of polyphenols, including anthocyanins, caffeic acid, and its derivatives also present in chokeberry at relatively high concentrations. Anthocyanins have antioxidant and anti-inflammatory properties and, therefore, may be potentially used to prevent(More)
BACKGROUND The significance of heavy metals in pathogenesis of the circulatory system diseases remains unresolved. The aim of the study was to evaluate electrocardiographic changes in workers occupationally exposed to lead without clinical presentation of cardiac involvement. METHODS A group of 60 smelters and refiners and 45 healthy men, as a control(More)
The aim of this study was to assess disability, psychological distress and quality of life in Polish breast cancer survivors with arm lymphedema. One thousand sets of questionnaires consisting of WHO-DAS II, GHQ-30, EORTC QLQ-C30 and QLQ-BR23 were sent to members of the Polish Federation of Breast Cancer Survivors Clubs "Amazonki." The response rate was(More)
We have evaluated current knowledge on relations between environmental and occupational exposure to lead with a strong emphasis on cardiovascular disease risk factors, such as the influence of lead compounds on lipid disturbances and arterial blood pressure. In addition, "novel" biochemical and vascular risk factors for cardiovascular diseases were(More)
OBJECTIVE The aim of the study was to identify factors associated with worse physical and emotional functioning of breast cancer survivors with upper extremity lymphedema. METHODS 1250 sets of questionnaires consisting of WHO-DAS II, EORTC QLQ-C30, EORTC QLQ-BR23 and GHQ-30 were mailed to women who underwent a breast cancer surgery at the Lower Silesian(More)
This pilot study was designed to investigate lymphatic transport in the arms of women after breast cancer treatment without lymphedema and with mild and severe arm lymphedema. Nineteen breast cancer survivors [6 without (Group 1), 6 with mild (Group 2) and 7 with severe (Group 3) lymphedema] were examined. Lymphatic transport in the arm and to axillary(More)
BACKGROUND The aim of the study was to evaluate the impact of exposure to lead and cadmium on concentrations of some lipids, lipid peroxidation, enzymatic and non-enzymatic efficiency of antioxidants in the rat brain as well as the effect of combined exposure to metals on the lipid parameters and the activity of antioxidative system. The authors also(More)
UNLABELLED Lead, cadmium and arsenic represent well recognized toxic agents which in a specific manner disturb function of cardiovascular system. Cystatin C has been accepted to be a significant prognostic factor for cardiovascular diseases. The study aimed at defining relationship between occupational exposure to lead, cadmium and arsenic on one hand and(More)
The hematopoietic system, due to intensive cells proliferation, is very sensitive to toxic substances. Many chemicals, including benzene, pesticides (dithiocarbamines), ethylene oxide and metals (mercury, cadmium, chrome, cobalt, lead, aluminum) exert their toxic effect on the hematopoietic system. Exposure to each of these substances may occur in the work(More)
