Specificity Determinants of the Silkworm Moth Sex Pheromone
The insect olfactory system, particularly the peripheral sensory system for sex pheromone reception in male moths, is highly selective, but specificity determinants at the receptor level are hitherto unknown. Using the Xenopus oocyte recording system, we conducted a thorough structure-activity relationship study with the sex pheromone receptor of the silkworm moth, Bombyx mori, BmorOR1. When co...
متن کاملBombykol receptors in the silkworm moth and the fruit fly.
Male moths are endowed with odorant receptors (ORs) to detect species-specific sex pheromones with remarkable sensitivity and selectivity. We serendipitously discovered that an endogenous OR in the fruit fly, Drosophila melanogaster, is highly sensitive to the sex pheromone of the silkworm moth, bombykol. Intriguingly, the fruit fly detectors are more sensitive than the receptors of the silkwor...
متن کاملSome Characteristics of Certain Reflexes
Records are presented which have been obtained from man by direct intra-arterial catheterization and electrocardiography. These records have been selected (1) because they offer evidence for the validity of Starling's law in intact man and (2) because they demonstrate that when the heart is influenced by activity of the so-called "intrinsic" reflexes these manifestations of Starling's law are m...
متن کاملEffects of Chlorpromazine on Some Motor Reflexes*~-
-The effects of chlorpromazine (CPZ) on the patellar reflex and segmentally evoked spinal cord potentials were determined in various cat preparations. CPZ in doses of I-8 mg/kg given intravenously (as an accumulative dose) produced a signiticant depression of the patellar reflex and segmentally evoked potentials in animals with an intact central nervous system. Hypotension, potentiation of anes...
متن کاملEffect of diabetes on some primitive reflexes.
Primitive reflexes (PRs) are present in newborns; they disappear as the brain matures and increase in frequency in healthy elderly individuals. Primitive reflexes are more frequent in some neurological disorders than in age-matched controls. The aim of this study was to investigate the effect of diabetes on some PRs. We examined three PRs (glabellar tap, snout and palmomental reflexes) in 376 s...
