The development of more efficient, ethical, and effective means of assessing the effects of chemicals on human health and the environment was a lifetime goal of Gilman Veith. His work has provided the foundation for the use of chemical structure for informing toxicological assessment by regulatory agencies the world over. Veith's scientific work influenced the early development of the SAR model...

In our highly complex and ever changing world it is reassuring to know that certain physical quantities can be measured and predicted with very high precision. Precision measurements have always appealed to me as one of the most beautiful aspects of physics. With better measuring tools, one can look where no one has looked before.

In every person's life, the time comes to take stock. The process is almost always painful and messy, but five practical strategies can help guide you and give your life new direction and meaning.

This study aimed to analyze the antiproliferative and genotoxic potential of synthetic food flavorings, nature identical passion fruit and artificial vanilla. This assessment used root meristem cells of Allium cepa L., in exposure times of 24 and 48 hours and using doses of 0.2; 0.4 and 0.6 mL. Roots were fixed in Carnoy's solution, hydrolyzed in hydrochloric acid, stained with acetic orcein an...

Recent evidence demonstrated that the explicit representation of love recruits subcorticocortical pathways mediating reward, emotion, and motivation systems. However, the neural basis of the implicit (unconscious) representation of love remains unknown. To assess this que...

This portrait is not unlike Freud’s Schreber, Lacan’s Schreber, and is certainly Schreber’s Schreber. Nevertheless, the understanding of Schreber’s mental hell comes out very different in this work and is affected here by the central use of a particular aspect of passi...

With the emergence of positive psychology and the subsequent positive organizational behavior movement, focusing on the employee experience and factors of positive psychological states in employees has come to the forefront. In recent years, several studies have emphasized the practical value of employee engagement and passion (the dualistic model of passion; Vallerand et al., 2003) in predicti...
