Pediatric dumbbell-shaped orbital schwannoma with extension to the cranial cavity: A case report and literature review.

Orbital schwannomas are rare in children, especially those with intracranial extension. Herein, our report refers to a 12-year-old boy who had a cranial-orbital mass with a dumbbell-like appearance. The total neoplasms was successfully removed a transcranial approach, and the pathological diagnostic result was schwannoma.

[Quantitative analysis of age-related changes of human major salivary glands using magnetic resonance imaging].

Objective: To analyze the age-related characteristics of volumes, signal intensities (SIs) of T1-weighted images (T1WI), T2-weighted images (T2WI) and apparent diffusion coefficients (ADCs) of three major salivary glands.

Methods: A total of 300 subjects with normal salivary glands were divided into 4 different age groups and examined with a 1.5 T magnetic resonance (MR) unit.

Hitch-hiking parasitic wasp learns to exploit butterfly antiaphrodisiac.

Many insects possess a sexual communication system that is vulnerable to chemical espionage by parasitic wasps. We recently discovered that a hitch-hiking (H) egg parasitoid exploits the antiaphrodisiac pheromone benzyl cyanide (BC) of the Large Cabbage White butterfly Pieris brassicae. This pheromone is passed from male butterflies to females during mating to render them less attractive to conspecific males.
