Oxidative stress in newborns by different modes of delivery.

Objectives: The aim of our study is to investigate the impact of the type of delivery - vaginal vs. cesarean section on oxidative damage determined as the lipid peroxidation (15-F2t-isoprostane (15-F2t-IsoP) in the cord blood of newborns and venous blood from mothers in two localities with different levels of air pollution: Ceske Budejovice (CB), a locality with a clean air, and Karvina, a locality with high air pollution.

Resutls: In Karvina, the concentration of PM2.

The impact of air pollution in the Southern Bohemia Region on fetuses and newborns.

Air pollution with increased concentrations of carcinogenic polycyclic aromatic hydrocarbons (c-PAHs, represented by benzo[a]pyrene, B[a]P) affect fetal development, reduce birth weights (LBW) of newborns, and increases intrauterine growth retardation (IUGR). The Southern Bohemia Region is believed to be one of the least air polluted regions in the Czech Republic. Monitoring air pollution in the city of České Budějovice from 2011-2015, PM2.

Medical and salutogenic approaches and their integration in taking prenatal and postnatal care of Czech women.

Objective: To compile a proposal of the system of taking complex prenatal, perinatal and postnatal care of pregnant women and their children in the Czech Republic with taking into account medical and salutogenic approaches.

Material And Methods: A questionnaire was prepared comprising questions for mothers and making it possible to exactly use specified data from their healthcare documentation. The method thus consisted of a secondary data analysis and subsequent contact with mothers.

Nonadaptive processes governing early stages of polyploid evolution: Insights from a primary contact zone of relict serpentine Knautia arvensis (Caprifoliaceae).

• Premise of the study: Contact zones between polyploids and their diploid progenitors may provide important insights into the mechanisms of sympatric speciation and local adaptation. However, most published studies investigated secondary contact zones where the effects of genome duplication can be confounded by previous independent evolution of currently sympatric cytotypes. We compared genetically close diploid and autotetraploid serpentine cytotypes of Knautia arvensis (Caprifoliaceae) in a primary contact zone and evaluated the role of adaptive and nonadaptive processes for cytotype coexistence.
