Article Synopsis
  • Scientists studied how insects like moths and fruit flies use smells (pheromones) to find their way and communicate.
  • They created a special device that sends short bursts of pheromones to see how the insect's sensory cells react.
  • Moths can recognize when the smell stops, but fruit flies can't do this well because they only need to communicate over short distances.

A case is reported of a 46-year-old woman referred to a magnetic resonance imaging (MRI) for menometrorrhagia. MRI revealed a mass lesion lateral to the uterus fundus, suspicious of an ovarian granulosa cell tumor. Extensive surgery was performed.

Objectives: The purpose of this study was to evaluate a three-material decomposition algorithm for hepatic fat quantification using a dual-layer computed tomography (DL-CT) and MRI as reference standard on a large patient cohort.

Method: A total of 104 patients were retrospectively included in our study, i.e.

In insects, juvenile hormone (JH) is critical for the orchestration of male reproductive maturation. For instance, in the male moth, Agrotis ipsilon, the behavioral response and the neuronal sensitivity within the primary olfactory centers, the antennal lobes (ALs), to the female-emitted sex pheromone increase with fertility during adulthood and the coordination between these events is governed by JH. However, the molecular basis of JH action in the development of sexual behavior remains largely unknown.

In the moth Agrotis ipsilon, the behavioral response of males to the female-emitted sex pheromone increases throughout adult life and following a prior exposure to sex pheromone, whereas it is temporally inhibited after the onset of mating. This behavioral flexibility is paralleled with changes in neuronal sensitivity to pheromone signal within the primary olfactory centers, the antennal lobes. In the present study, we tested the hypothesis that neuroligins, post-synaptic transmembrane proteins known to act as mediators of neuronal remodeling, are involved in the olfactory modulation in A.
