The effect of the RadioProtect cosmetic formulation on the skin of oncological patients treated with selected cytostatic drugs and ionizing radiation.

Introduction: According to the Polish Central Statistical Office and the National Cancer Registry, cancer is the main cause of death in the world. Every year over 8 million people die from cancer worldwide, while in Poland the disease kills nearly 100,000 people. The group of patients analysed in this study suffered from breast, colorectal and lung cancers, and underwent radio- and chemotherapy.

Application of the rough sets theory in structure activity relationship of antielectrostatic ammonium compounds.

The relationships between the chemical structure and the antielectrostatic effect of 112 ammonium compounds were analysed using the method of rough sets. The antielectrostatic activity was determined by measurements of the maximum voltage induced. Using the rough sets approach the smallest set of condition attributes significant for high quality of classification has been found.
