An Overview of the Possible Exposure of Infants to Microplastics.

Microplastics are small plastic pieces with sizes less than 5 mm. They are becoming a global concern due to the potential risk to human health. The potential risks of microplastics may be greater for infants because they do not have sufficiently developed metabolizing enzymes, have less ability to remove microplastics, and have highly sensitive target organs.

Relationship between Eating Habits and 4-Nonylphenol Concentration in Breast Milk of Women in Slovakia.

4-Nonylphenol belongs to the alkylphenol group of chemicals, and its high occurrence in the environment can cause an adverse effect on human health. Breast milk can serve as a marker to take measure of human exposure to these chemicals through different routes of exposure. In this work, the influence of selected factors (the kind of water drank by the mothers; the consumption of fish, pork, and beef; wearing gloves; using nail polish, gel nails, vitamins, and medication) on the concentration on 4-nonylphenol in 89 breast milk samples was studied.

Determination of vitamin D, iron and n-3 fatty acids in adolescents with different eating habits.

Objectives: Proper eating habits ensure human health, so it is important to eat a balanced diet and learn the basics of proper eating from an early age. Adolescence is considered very important period for maintaining good health in terms of nutrition.

Methods: In the study, we monitored the eating habits of 182 adolescents aged 14-19 years with different eating habits (73 vegetarians and 109 nonvegetarians) using a questionnaire on nutrition and determination of selected blood parameters - vitamin D, iron and n-3fatty acids.

The Need for Nurse Interventions in Sex Education in Adolescents.

Developmentally appropriate evidence-based sexual health education should be included as part of a comprehensive school health education program and be accessible to all students. The registered school nurse is a valuable resource to parents and educators in this area and supports the implementation of evidence-based sexual health education programs that promote healthy sexual development for adolescents. The research group consisted of 438 adolescents aged 12 to 15 years in a selected region in Slovakia, 186 boys and 252 girls.

Fungal neuroinfections and fungaemia: unexpected increase of mortality from invasive fungal infections in 2005-2011 in comparison to 1989-1998: analysis of 210 cases.

Objective: In this short communication we compared the data of fungaemia cases in Slovak hospitals from 1989-1998 published in 1999-2000 with data from 2005-2011.

Methods: Risk factors, etiology and outcome of fungaemia between two periods (1989-1998 vs. 2005-2011) were compared and risk factors for death assessed by univariate analysis (CDC 2006 Statistical Package).

Lif1 SUMOylation and its role in non-homologous end-joining.

Non-homologous end-joining (NHEJ) repairs DNA double-strand breaks by tethering and ligating the two DNA ends. The mechanisms regulating NHEJ efficiency and interplay between its components are not fully understood. Here, we identify and characterize the SUMOylation of budding yeast Lif1 protein, which is required for the ligation step in NHEJ.
