Influence of Tryptophan and Serotonin on Mood and Cognition with a Possible Role of the Gut-Brain Axis.

Abstract: The serotonergic system forms a diffuse network within the central nervous system and plays a significant role in the regulation of mood and cognition. Manipulation of tryptophan levels, acutely or chronically, by depletion or supplementation, is an experimental procedure for modifying peripheral and central serotonin levels. These studies have allowed us to establish the role of serotonin in higher order brain function in both preclinical and clinical situations and have precipitated the finding that low brain serotonin levels are associated with poor memory and depressed mood. The gut-brain axis is a bi-directional system between the brain and gastrointestinal tract, linking emotional and cognitive centres of the brain with peripheral functioning of the digestive tract. An influence of gut microbiota on behaviour is becoming increasingly evident, as is the extension to tryptophan and serotonin, producing a possibility that alterations in the gut may be important in the pathophysiology of human central nervous system disorders. In this review we will discuss the effect of manipulating tryptophan on mood and cognition, and discuss a possible influence of the gut-brain axis.

Strategies for controlling biofouling in membrane filtration systems: challenges and opportunities

Abstract: Biofouling is a critical problem in many membrane filtration processes. This review highlights the emerging strategies for polymer membrane modifications using organic and inorganic additives and surface modification to mitigate foulant deposition and biofilm formation. Constraints and opportunities for future implementation in membrane systems are outlined from the perspectives of water and wastewater treatment applications.

Alternative management accounting research—whence and whither

Abstract: This paper reviews alternative management accounting research in AOS from 1976 until 1999. We highlight seven different research perspectives that have flourished under this label: a non-rational design school; naturalistic research; the radical alternative; institutional theory; structuration theory; a Foucauldian approach; and a Latourian approach. It is contended that these different approaches have assumed an important role in raising a number of significant and interesting disciplinary insights. As a form of collective non-positivist enterprise, alternative management accounting research has demonstrated: the many different rationalities of management accounting practice; the variety of ways in which management accounting practice is enacted and given meaning; the potency of management accounting technologies; the unpredictable, non-linear and socially-embedded nature of management accounting change; and the ways in which management accounting practice is both constrained and enabled by the bodily habitudes of its exponents. In conclusion, we consider how alternative management accounting research may sustain its distinct contributions in the future.
