Organochlorinated hydrocarbons, i.e. polychlorinated biphenyls (PCBs) and pesticides (e.g. dieldrin, lindane, etc.), are chemically and microbiologically resistant pollutants. These molecules can also be absorbed through the skin and become a safety concern. Therefore it is important to investigate ...

This study is part of an extensive research program on pheromones aiming to analyze in depth and on a wide scale man's olfaction and its ability to distinguish pheromone-like substances either of male and female origin, as well as the evolution of such ability at different physiological stages durin...

Three emulsions of similar viscosity were prepared from the same components: one W/O emulsion and two O/W/O emulsions which differ by their relative wax amounts. Three parameters were taken into account to compare these preparations: acceptability, remanence and occlusivity. With the O/W/O emulsions...

This study is part of a research on chemical communication in Man. It investigates the perception of pheromonal substances in adults. Since it seems that the perception of certain odours and the capability to distinguish personal smells are related to sex and sexual maturity, olfactive tests were ma...

Recent experiments on mice casually lead to the discovery that, in such animals, histocompatibility antigens can act as olfactory markers and help recognising the most suitable partner. Selecting a companion bearing antigens of different type is likely to lead to an offspring which, being mostly het...
