The 40-Year Mystery of Insect Odorant-Binding Proteins
2021
International audience; The survival of insects depends on their ability to detect molecules present in their environment. Odorant-binding proteins (OBPs) form a family of proteins involved in chemoreception. While OBPs were initially found in olfactory appendages, recently these proteins were discovered in other chemosensory and non-chemosensory organs. OBPs can bind, solubilize and transport hydrophobic stimuli to chemoreceptors across the aqueous sensilla lymph. In addition to this broadly accepted “transporter role”, OBPs can also buffer sudden changes in odorant levels and are involved in hygro-reception. The physiological roles of OBPs expressed in other body tissues, such as mouthpar…
Ocean acidification affects fish spawning but not paternity at CO2 seeps
2016
Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse ( Symphodus ocellatus ) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ between sites with ambient versus elevated CO 2 concentrations. Dominant males did, however, experience significantly lower rates of pair spawning at elevated CO 2 levels. Despite the hig…
Immediate effects of wearing knee length socks differing in compression level on postural regulation in community-dwelling, healthy, elderly men and …
2018
Background Stimulation of lower limbs’ cutaneous receptors and mechanoreceptors through compression garments could potentially increase somatosensory system efficiency and aid postural regulation in elderly individuals. Research question This study examined immediate effects of wearing knee length socks (KLS) of various compression levels on somatosensory function in community-dwelling healthy elderly men and women during a double-limb standing, balancing task. Methods A total of forty-six elderly participants (Male = 23), aged between 65 and 84 years old, randomly selected from the Singapore community-dwelling, healthy population. Three treatment interventions (wearing clinical compression…

Cartesian Psychology – Could There Be One?
2008
The chapter examines what it would mean to talk about “psychology” in Descartes’ terms and argues that within the Cartesian framework we cannot really formulate the questions that are posed by contemporary psychologists. This results from the fact that psychological topics can be found on all three levels of Cartesian science: in metaphysics, in physics and finally in the applied sciences, such as medicine and morals. The aim is to show that the sensory and vegetative functions are often taken together by Descartes. Therefore, the Cartesian system does not recognize any principal difference between sensory functions, such as vision, and vegetative functions, such as digestion. Humans can be…
