Max Planck Institute for Chemical Ecology, Jena, Germany. This review covers the research on brown algal pheromones from the first structural characterisation of an active principle in 1971 to the recent detailed insight into their biosynthesis. Developmen ...
Group sequential methods find a particular field of application in clinical trials because patient recruitment is by nature sequential. It is important to minimize the number of patients exposed to an inferior treatment. Moreover, the experimenter is requi ...
UMR 1931, CNRS and Laboratoires Goemar, Station Biologique, 29680 Roscoff, France. Marine algae encompass lineages that diverged about one billion years ago. Recent results suggest that they feature natural immunity traits that are conserved, as well as ot ...
The developments in EMC modelling permit to estimate the disturbances in different kinds of circuits and installations, to define a protection philosophy and to evaluate its efficiency. Using some examples of modelling, the paper discusses whether these po ...
The time of sit-stand and stand-sit transition and its duration were measured using a miniature gyroscope on the chest and a portable recorder on the waist Based on a simple model and wavelet analysis, three parameters related to postural transition, namel ...
Protoporphyrin IX (PpIX) is used as a fluorescence marker and photosensitizing agent in photodynamic therapy (PDT). A temporary increase of PpIX in tissues can be obtained by administration of 5-aminolevulinic acid (ALA). Lipophilicity is one of the key pa ...
