Evaluation of the effectiveness of laser photoselective vaporization of the prostate in the treatment of patients with benign prostatic hyperplasia.

Introduction: The prolongation of the life of men results in the growing number of people suffering from benign prostatic hyperplasia (BPH). In 2010, BPH concerned more than 200 million men in the whole world, which at that time made up 6% of the population of men at large. Currently, the population of men in the world amounts about three billion six hundred million.

Smoking-related behaviours of pregnant women depending on their place of residence.

Objectives: Smoking is a commonly recognized risk factor of civilization diseases. Despite many educational programmes concerning harmful effects of tobacco smoking, this habit is still very popular. Particularly alarming is a high percentage of pregnant women who smoke.

Oxidative stress in colonic adenocarcinoma: An impact on the body's antioxidative status and oxidative protein damage.

Background: Thus far, the pathogenesis of these intestinal tumors has not been fully explained. However, the analysis of risk factors and research regarding their formation that have continued for 3 decades have allowed us to demonstrate a significant role of oxidative stress in the processes leading to the development of cancer in the large intestine as well as in some other organs.

Objectives: The aim of the study was to examine the level of anti-oxidative status and the degree of oxidative protein damage in patients with varying severity of colonic adenocarcinoma (CAC) in relation to healthy individuals.

Impact of electromagnetic radiation emitted by monitors on changes in the cellular membrane structure and protective antioxidant effect of vitamin A - In vitro study.

Objectives: The increasing number of devices emitting electromagnetic radiation (EMR) in people's everyday life attracted the attention of researchers because of possible adverse effects of this factor on living organisms. One of the EMR effect may be peroxidation of lipid membranes formed as a result of free radical process. The article presents the results of in vitro studies aimed at identifying changes in malondialdehyde (MDA) concentration - a marker of lipid peroxidation and antioxidant role of vitamin A during the exposure of blood platelets to electromagnetic radiation generated by liquid-crystal-display (LCD) monitors.
