Juvenile polyposis syndrome (JPS) is a rare autosomal dominant disorder characterised by multiple gastrointestinal juvenile polyps and an increased risk of colorectal cancer. This caused germline mutation either SMAD4 or BMPR1A, possibly ENG. PTEN, originally linked to Cowden Bannayan-Riley-Ruvalcaba syndrome, has also been associated with JPS. By direct sequencing, mutations are found in only 30-40% patients JPS phenotype. Therefore, alternative ways inactivation the known genes, additional...

The risk posed by complex chemical mixtures in the environment to wildlife and humans is increasingly debated, but has been rarely tested under environmentally relevant scenarios. To address this issue, two of 14 or 19 substances concern (pesticides, pharmaceuticals, heavy metals, polyaromatic hydrocarbons, a surfactant, plasticizer), each present at its safety limit concentration imposed European legislation, were prepared for their toxic effects. effects assessed 35 bioassays, based on 11...

The aim of the present study was to investigate effect silver nanoparticles (AgNP) different sizes toward two primary producer aquatic species. Thalassiosira pseudonana and Synechococcus sp. have been selected as representative models for lower trophic organisms in marine freshwater habitats, respectively. Time-dependent cellular growth measured upon exposure both AgNP nitrate (AgNO(3)). In addition, behavior waters has followed by CPS disc centrifuge, time frame studies, kinetic release...

Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants ubiquitously distributed. They generated by incomplete combustion of organic materials such as wood or fossil fuels. Due to their carcinogenic, mutagenic effects and wide distribution in the environment, these pose many concerns researchers regulators. In our laboratories we investigated effect benzo(a)pyrene (BaP) exposure marine diatom Thalassiosira pseudonana, which has become an important model organism aquatic...

Diatoms are unicellular, photosynthetic, eukaryotic algae with a ubiquitous distribution in water environments and they play an important role the carbon cycle. Molecular or morphological changes these species under ecological stress conditions expected to serve as early indicators of toxicity can point global impact on entire ecosystem. Thalassiosira pseudonana, marine diatom first fully sequenced genome has been selected aquatic model organism for ecotoxicological studies using molecular...
