Maternal Dietary Choline Status Influences Brain Grey and White Matter Development in Young Pigs

Abstract

Background

Choline is an essential nutrient that is pivotal to proper brain development. Research in animal models suggests that perinatal choline deficiency influences neuron development in the hippocampus and cortex, yet these observations require invasive techniques.

Objective

This study aimed to characterize the effects of perinatal choline deficiency on grey and white matter development using non-invasive neuroimaging techniques in the young pig.

A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults

Abstract

Objective 

We performed a systematic review, meta-analysis and meta-regression to determine if dietary protein supplementation augments resistance exercise training (RET)-induced gains in muscle mass and strength.

Data sources 

A systematic search of Medline, Embase, CINAHL and SportDiscus.

Eligibility criteria 

Only randomised controlled trials with RET ≥6 weeks in duration and dietary protein supplementation.
