Three-phase partitioning as an elegant and versatile platform applied to nonchromatographic bioseparation processes.

In recent years, a big trend has been the development of rapid, green, efficient, economical, and scalable approaches for the separation and purification of bioactive molecules from natural sources, which can be used in food, cosmetics, and medicine. As a new nonchromatographic bioseparation technology, three-phase partitioning (TPP) is attracting the attention of a growing number of scientists and engineers. Although a number of studies have been published in the last 40 years regarding the extraction, separation, and purification of numerous bioactive molecules using TPP systems, a background review on TPP partitioning fundamentals and its applications is much needed.

Implementation of a Psychiatric Nurse-led Outreach Service for Adults Residing at Subvented Old Age Homes: A Hong Kong Experience.

This paper reports on the implementation of a pioneering psychiatric nurse-led service that was designed to address the unmet mental healthcare needs of adults residing at subvented old age homes. It also describes features of potentially wider relevance to nurses interested in developing healthcare service for other underserved populations. We highlight the view that the crux of developing a successful service involves understanding existing service gaps; grasping the pulse of changing healthcare service policies; involving relevant stakeholders in the planning process; validating service outcomes; and seeking support from management.
