  • Endocrine Disruptors

    Endocrine disruptors are natural or synthetic chemical substances that can adversely affect the endocrine systems of humans and animals. They interfere with the normal function of hormones and may impair growth, development, reproduction, and other physiological processes. Exposure to endocrine disruptors has been associated with an increased risk of various health disorders. These substances may be present in everyday products such as plastics, cosmetics, children's toys, and food-contact materials. Their effects on human health and the environment are an increasingly important focus of environmental and public health research.

  • Epigenetics

    Epigenetics is the study of mechanisms that regulate gene activity without altering the underlying DNA sequence. One of the central questions in epigenetics is the extent to which environmental factors influence gene expression. External factors such as nutrition and stress can induce epigenetic modifications that regulate gene activity. In plants and invertebrates, some of these modifications can be inherited, whereas heritable epigenetic changes are relatively rare in mammals. Epigenetic processes may be influenced by the organism's own signalling mechanisms as well as by lifestyle factors, including dietary habits.
