Further, the researchers report today in the Journal of the Royal Society Interface, a dog's nose has a unique nasal airflow pattern, which helps transport odor molecules quickly via a single airway to the olfactory recess.
OBPs are soluble proteins that facilitate the activation of olfactory receptors by transporting odor molecules through the antennal lymph to the receptors in the olfactory membrane [ 73- 75].
To address a common limitation of research into connections between odor and health based on self-report without objective measures, we measured hydrogen sulfide, a product of anaerobic decomposition of hog waste, and particulate matter ≤ 10 μm in aerodynamic diameter (PM10), which can transport odorant chemicals (Bottcher 2001); at the same time participants rated the strength of hog odor.
When Emmylou Harris visited the steaming geothermal pools at Mammoth Hot Springs, their sulfurous odor transported her back to when she was five years old, in Birmingham, Alabama.
The study is an elegant demonstration of the importance of odor transport, says Gabrielle Nevitt, a sensory ecologist at the University of California, Davis.
On the surface, the issue of bottle closures would not seem to stir the soul, unless you've uncorked a precious old wine and found not the aroma of transporting romance but the odor of moldy cardboard.
The company later determined that a byproduct of a chemical used to treat wooden transport pallets had caused the odor.
The products may be contaminated with a byproduct of a chemical used to treat wooden transport pallets, causing a moldy odor in the bottles.
Predator odor exposure (with or without additional transport stress) increased c-Fos immunoreactivity in the BNST, but not the MPOA, relative to control odor exposure, suggesting that the BNST may play an important role in integration of threat cues and transduction of their meaning into long-term effects on expression of maternal care.
OBPs bind odor molecules, most of which are hydrophobic, and transport them through the hydrophilic environment in the sensillum to the membrane-bound receptor.
