1. Endocrine Disruption in Amphibians : Developmental Effects of Ethynylestradiol and Clotrimazole on the Reproductive System
Abstract : Amphibian populations are declining world-wide and one of the suggested reasons is environmental pollutants. Studies of long-term effects on the reproductive system in frogs following larval exposure to environmental pollutants are scarce. It is therefore important to develop methods to study developmental reproductive toxicity in amphibians. READ MORE

2. Endocrine modulators and sexual differentiation in Japanese quail : With emphasis on the neuroendocrine system
Abstract : Chemical disruption of the endocrine system in various animal species is currently attracting considerable interest, but avian models are not yet widely used in studying endocrine disturbances. This thesis shows the occurrence of alterations in sexual behavior and reproductive organs in adult Japanese quail (Coturnix japonica) following embryonic exposure to estrogen-like chemicals.

3. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds
Abstract : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. READ MORE

5. An experimental study on the interaction between the neuro-endocrine and immune systems in the gastrointestinal tract
Abstract : The mucosa lining of the gastrointestinal (GI) tract is in immediate contact with food nutrients to allow a rapid and efficient digestion and absorption and at the same time protects against the incessant risk of attack from pathogenic microbes. Maintenance of normal physiological activities in the GI tract is dependent on a number of regulatory interactions between the nervous, endocrine, and immune systems, as well as environmental and genetic factors.
