Separation of cryopreserved human semen using Sephadex columns, washing, or Percoll gradients.
Journal of Andrology, 1991 The following methods were evaluated for their ability to separate motile cryopreserved sperm from semen after thawing: single washing, Percoll separation followed by a single washing, and Sephadex column separation. For Sephadex separation, washing, and

Small, EarlyView.Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Plant, Cell &Environment, EarlyView.ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.
