Abstract:
... Sustainability certification has become an increasingly important feature in aquaculture production, leading to a multitude of schemes with various criteria. However, the large number of schemes and the complexity of the standards creates confusion with respect to which sustainability objectives are targeted. As a result, what is meant by ‘sustainability’ is unclear. In this paper, we examine the ...

Abstract:
... Autophagy is a fundamental bulk intracellular degradation and recycling process that directly eliminates intracellular microorganisms through “xenophagy” in various types of cells, especially in macrophages. Meanwhile, bacteria have evolved strategies and cellular self-defense mechanisms to prevent autophagosomal degradation and even attack the immune system of host. The lack of knowledge about th ...
