Background & aims: Postoperative hyperglycaemia is common in patients having major surgery and is associated with adverse outcomes. This study aimed to determine whether bacteraemia contributed to postoperative systemic inflammation, and whether incr...

Human skeletal muscle is refractory to the anabolic effects of leucine during the postprandial muscle-full period in older men (2017)
Journal Article
Mitchell, W. K., Phillips, B. E., Hill, I., Greenhaff, P. L., Lund, J. N., Williams, J. P., …Atherton, P. J. (2017). Human skeletal muscle is refractory to the anabolic effects of leucine during the postprandial muscle-full period in older men. Clinical Science, 131(21), https://doi.org/10.1042/CS20171230

Leucine modulates muscle protein synthesis (MPS), with potential to facilitate accrual/maintenance of muscle mass. Animal models suggest that leucine boluses shortly after meals may prolong MPS and delay onset of a “muscle-full” state. However, the e...

© 2017 The Authors Background & aims: Impaired anabolic responses to nutrition and exercise contribute to loss of skeletal muscle mass with ageing (sarcopenia). Here, we tested responses of muscle protein synthesis (MPS), in the under represented gr...

Muscle thickness correlates to muscle cross sectional area in the assessment of strength training induced hypertrophy (2017)
Journal Article

Muscle thickness correlates to muscle cross sectional area in the assessment of strength training induced hypertrophy. Scandinavian Journal of Medicine and Science in Sports, 28(3), https://doi.org/10.1111/sms.12961

Aim: Muscle thickness (MT) measured by ultrasound has been used to estimate cross-sectional area (measured by CT and MRI) at a single time-point. We tested whether MT could be used as a valid marker of MRI determined muscle anatomical cross-sectional...

Physiological adaptations to resistance exercise as a function of age (2017)
Journal Article

BACKGROUND. The impact of resistance exercise training (RE-T) across the life span is poorly defined. METHODS. To resolve this, we recruited three distinct age cohorts of young (18–28 years; n = 11), middle-aged (45–55 years; n = 20), and...

A novel D2O tracer method to quantify RNA turnover as a biomarker of de novo ribosomal biogenesis, in vitro, in animal models, and in human skeletal muscle (2017)

AJP - Endocrinology and Metabolism, 313(6), Article E681-E689. https://doi.org/10.1152/ajpendo.00157.2017

Current methods to quantify in vivo RNA dynamics are limited. Here, we developed a novel stable isotope (D2O) methodology to quantify RNA synthesis (i.e., ribosomal biogenesis) in cells, animal models, and humans. First, proliferating C2C12 cells wer...

Muscle carnitine availability plays a central role in regulating fuel metabolism in the rodent (2017)
Journal Article

The body carnitine pool is primarily confined to skeletal muscle, where it regulates carbohydrate (CHO) and fat usage. Mildronate (3-(2,2,2-trimethylhydrazinium)-propionate) inhibits carnitine synthesis and tissue uptake, but the impact of carnitine...

The peroxisome proliferator-activated receptor γ (PPARγ) agonist rosiglitazone (Rosi) appears to provide protection against organ dysfunction during endotoxaemia. We examined the potential benefits of Rosi on skeletal muscle protein maintenance and c...
