Background. Ionizing radiation (IR) carry adequate energy to ionize or remove electrons from an atom. Particles interact with water to produce reactive oxygen species (ROS). Genistein (GEN) is a naturally occurring phytoestrogen and the basic isoflavonoid in soybeans and soybean-enriched products and is believed to have the strongest antioxidant activity. Objective. The study aimed at the investigation...
Lutein and zeaxanthin are naturally occurring xanthophylls, mainly present in green, leafy vegetables and egg’s yolk. Their presence is connected with blue spectrum light absorbance, including UV. This property, and fact, that these xanthophylls are accumulated by human eye’s macula, leads to eye’s protective functions of them including protection from age-related macular degeneration (AMD). Also,...
Radon is noble, monatomic, radioactive, heavier than the air gas. It is colorless, odorless, tasteless. It exists in natural environment as a result of the decay of radium, and emits mainly alpha radiation and less beta radiation. Residential radon concentrations vary widely by geographic area. The higher concentration of radon is expected globally in the grounds where uranium, radium and thoron are...
Maria Skłodowska was born on November 7, 1867 in Warsaw (Poland). Her parents were teachers. Maria’s mother has died in 1878 of tuberculosis. In 1893 and 1894, respectively, Maria was awarded master’s degrees in physics and in mathematics from the Sorbonne University. In 1895 Maria married Pierre Curie. In 1897 their daughter Irene was born. Maria investigated rays emitted by uranium salts. She hypothesized...
Phthalates are widely present in human environment. Widespead exposure to those agents, which are compounds of numerous daily use products, is unavoidable. In the current paper following phthalates benzylbutyl phthalate (BBP), din- butyl phthalate (DBP), di(2-ethylhexyl)phthalate (DEHP), diethyl phthalate (DEP), di-isononyl phthalate (DINP) are described. Phthalates mainly enter to the composition...
The general exposure to endocrine disruptors, including phthalates, is considered as one of the reason diminished sperm count and deteriorated sperm quality, which may lead to infertility and higher incidence of congenital malformations of the genital tract. This article describes the effects of selected phthalates di(2-ethylhexyl)phthalate (DEHP), dibutyl phthalate (DBP); butylbenzyl phthalate (BBP),...
Ionizing radiation may cause damage to living tissue by producing free radicals like reactive oxygen species (ROS). ROS can randomly react with lipids, proteins and nucleic acids of cell causing oxidative stress and damage in these macromolecules, leading to pathogenesis of chronic diseases and age related and also cancer. The first line of defense from the damaging effects of ROS is antioxidants,...
Public feelings concerning radiation are still controversy. The main sources of trouble seems to be the failure nuclear power plant and danger of terroristic attack, which may cause temporally enhanced level of radiation leading to harmful health effects. Since radiation induced cellular damage is attributed primarily to harmful effect of free radicals, molecules with direct free radical scavenging...
Di-(2-ethylhexyl)phthalate (DEHP) is widely present in the human environment. The study aimed at the investigation of potential genotoxic effects induced by subchronic exposure to DEHP in germ cells of male mice in the first period of puberty, and to check if the transmission of mutation to the next generation via the sperm is possible. 8-weeks exposure to 2,000 mg/kg and 8,000 mg/kg of DEHP diminished...
Celem pracy było zbadanie wpływu bisfenolu A oraz skojarzonego działania promieniowania X i bisfenolu A na indukcję mikrojąder w retikulocytach krwi obwodowej i szpiku kostnego samców myszy. Myszy Pzh:Sfis przez 2 tygodnie napromieniano promieniowaniem X (0,05 Gy i 0,10 Gy) lub podawano im bisfenol A (5 mg/kg mc, 10 mg/kg mc, 15 mg/kg mc, 20 mg/ kg mc, 40 mg/kg mc) lub poddawano skojarzonemu działaniu...
Phthalate are found in the environmental samples due to their wide use in the industry as plasticizers. Di-n-butyl phthalate (DBP) is mainly used in nitrocellulose and polyvinyl acetate products as well as in personal-care products. This study was performed to investigate the influence of exposure to DBP on the quantity and quality (motility, morphology) and DNA damage (induction of micronuclei and...
