Individual, health system, and contextual barriers and facilitators for the implementation of clinical practice guidelines: a systematic metareview.

Introduction: Clinical practice guidelines (CPGs) are designed to improve the quality of care and reduce unjustified individual variation in clinical practice. Knowledge of the barriers and facilitators that influence the implementation of the CPG recommendations is the first step in creating strategies to improve health outcomes. The present systematic meta-review sought to explore the barriers and facilitators for the implementation of CPGs.

The Bacterial Phytoene Desaturase-Encoding Gene () is an Efficient Selectable Marker for the Genetic Transformation of Eukaryotic Microalgae.

Genetic manipulation shows great promise to further boost the productivity of microalgae-based compounds. However, selection of microalgal transformants depends mainly on the use of antibiotics, which have raised concerns about their potential impacts on human health and the environment. We propose the use of a synthetic phytoene desaturase-encoding gene () as a selectable marker and the bleaching herbicide norflurazon as a selective agent for the genetic transformation of microalgae.
