Therefore we propose that the nonaesthetasc pathway of odorant
processing is necessary but not sufficient for modulating antennular flicking behavior toward chemical stimuli.
It suggests that there may be some logic in the way that odorant
molecules are represented in the cortex," says Zou.
The magnitude of these sorption processes was determined by measuring the heats of adsorption and interaction of the odorants
on clay and organo-clay substrates.
Methods for measuring odor emissions are controversial because the science of measuring odorants
is still in the early stages.
During the first phase of this experiment, one group of food-deprived test subjects was exposed to odorants
arising from food-deprived donors and a second group of food-deprived test subjects was exposed to odors from water-deprived donors.
On the basis of published stable isotope dilution assays, using comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry, German scientists monitored differences in the concentrations of key odorants
in different hazelnut cultivars roasted under specific conditions.
It is thought that OBPs in the insect antennae and mouth parts function to concentrate odorant
molecules and assist in their transport to the actual olfactory receptors, thereby allowing for odorant
His team recently found that primary blood cells isolated from human blood samples are attracted to the odorant
molecules responsible for producing a certain aroma.
There are a number of chemical and physical phenomena that can give rise to depletion of the concentration of odorants
, particularly mercaptans, in natural gas or LPG.
were quantified by stable isotope dilution assays.
In addition, 4 bio-functional odorants
were selected, all of which elicited significant electroantennogram (EAG) responses in other Coleoptera species but had not been tested in A.
It has been sued by the state of California and Reuters reported that over 20 lawsuits have been filed by residents as people complained of headaches, nausea and respiratory irritation from the odorants
added to natural gas.
