In a review of nutrition and ageing (Munro, 1981), it was suggested that research on this topic can be divided into three headings. First, there are the changes in body composition and physiological function that occur progressively throughout adult life. In most cases it is uncertain whether these processes are responsive to nutritional status. Second, some chronic diseases and disabilities of...

Deficits in the ability to perceive facial and vocal emotion expression are common in schizophrenia. However, relatively little is known about how such deficits might affect functional outcomes.

The purpose of the present study was to process sleep spindles with Independent Component Analysis (ICA) in order to investigate the possibility of extracting, through visual analysis of the sp...

The 60 participants included clinicians, academic researchers, engineers, patient advocates, caregivers, members of the public, and federal re...

Purposeful infection of healthy volunteers with a microbial pathogen seems at odds with acceptable ethical standards, but is an important contemporary research avenue used to study infectious diseases and their treatments. Generally termed ‘controlled human infection studies’, this research is particularly useful for fast tracking the development of candidate vaccines and may provide unique ins...
