Mesocestoides corti intracranial infection as a murine model for neurocysticercosis.

abstract：:In this article I begin with a few current ideas on some physiological factors that influence mating choice in insects. Emphasis is placed on those proteins produced by the male reproductive accessory glands which increase female fecundity and reduce her receptivity to subsequent males. Strategies used by late-arrivin...
