Olfaction plays an important role in insect behaviours. The odorant receptor (OR) repertoire, housed within the dendritic membrane of sensory neurons, is one of the primary determinants of odour recognition. ORs in moths could be classified into pheromone receptors (PRs) and non-pheromone receptors (non-PR ORs). Much research in the field of insect(More)
The sex pheromone communication system in moths is highly species-specific and extremely sensitive, and pheromone receptors (PRs) are thought to be the most important factors in males. In the present study, three full-length cDNAs encoding PRs were characterized from Sesamia inferens antennae. These three PRs were all male-specific in expression, but their(More)

Plasma endothelin level (ET) was measured by radioimmunoassay in 10 healthy non-pregnant women, 10 normal pregnancies, 41 cases with pregnancy induced hypertension (PIH), and in cord plasma of 19 normotensive and 14 PIH women as well. There was no significant difference of ET levels between non-pregnant and normal pregnant women (P > 0.05). On the contrary,(More)
