Creatinine and myoglobin are poor predictors of anaerobic threshold in colorectal cancer and health (2015)
Journal Article
Nyasavajjala, S. M., Phillips, B. E., Lund, J. N., & Williams, J. P. (2015). Creatinine and myoglobin are poor predictors of anaerobic threshold in colorectal cancer and health. Journal of Cachexia, Sarcopenia and Muscle, 6(2), https://doi.org/10.1002/jcsm.12020

Aims Myoglobin is a haem protein produced in skeletal muscles. Serum concentrations of myoglobin have been proposed as a surrogate marker of muscle mass and function in both cachectic cancer patients and healthy non-cancer individuals. Creatinine,...

Intake of low-dose leucine-rich essential amino acids stimulates muscle anabolism equivalently to bolus whey protein in older women at rest and after exercise (2015)
Journal Article
Bukhari, S. S., Phillips, B. E., Wilkinson, D. J., Limb, M. C., Rankin, D., Mitchell, W. K., …Atherton, P. J. (2015). Intake of low-dose leucine-rich essential amino acids stimulates muscle anabolism equivalently to bolus whey protein in older women at rest and after exercise. AJP - Endocrinology and Metabolism, 308(12), E1056-E1065. https://doi.org/10.1152/ajpendo.00481.2014

© 2015 American Physiological Society. All Rights Reseved. Dysregulated anabolic responses to nutrition/exercise may contribute to sarcopenia; however, these characteristics are poorly defined in female populations. We determined the effects of two f...

A dose- rather than delivery profile-dependent mechanism regulates the "muscle-full" effect in response to oral essential amino acid intake in young men (2014)
Journal Article
Mitchell, W. K., Phillips, B. E., Williams, J. P., Rankin, D., Lund, J. N., Smith, K., & Atherton, P. J. (2015). A dose- rather than delivery profile-dependent mechanism regulates the "muscle-full" effect in response to oral essential amino acid intake in young men. Journal of Nutrition, 145(2), https://doi.org/10.3945/jn.114.199604

Background: The anabolic response of skeletal muscle to essential amino acids (EAAs) is dose dependent, maximal at modest doses, and short lived, even with continued EAA availability, a phenomenon termed “muscle-full.” However, the effect of EAA inge...

Protein Carbonylation and Heat Shock Proteins in Human Skeletal Muscle: Relationships to Age and Sarcopenia (2014)
Journal Article

Aging is associated with a gradual loss of muscle mass termed sarcopenia, which has significant impact on quality-of-life. Because oxidative stress is proposed to negatively impact upon musculoskeletal aging, we investigated links between human aging...

Surgical resection of primary tumour improves aerobic performance in colorectal cancer (2013)
Journal Article
Williams, J. P., Nyasavajjala, S. M., Phillips, B. E., Chakrabarty, M., & Lund, J. N. (2014). Surgical resection of primary tumour improves aerobic performance in colorectal cancer. EJSO - European Journal of Surgical Oncology, 40(2), https://doi.org/10.1016/j.ejso.2013.11.009

Background Colorectal cancer is the third most common cancer in the UK, with patients suffering declines in muscle mass and aerobic function. We hypothesised that tumour removal in non-metastatic colorectal cancer would lead to a restoration of le...

Pharmacological enhancement of leg and muscle microvascular blood flow does not augment anabolic responses in skeletal muscle of young men under fed conditions (2013)
Journal Article
Phillips, B. E., Atherton, P. J., Varadhan, K., Wilkinson, D. J., Limb, M. C., Selby, A. L., …Williams, J. P. (2014). Pharmacological enhancement of leg and muscle microvascular blood flow does not augment anabolic responses in skeletal muscle of young men under fed conditions. AJP - Endocrinology and Metabolism, 306(2), Article E168-E176. https://doi.org/10.1152/ajpendo.00440.2013

Skeletal muscle anabolism associated with postprandial plasma aminoacidemia and insulinemia is contingent upon amino acids (AA) and insulin crossing the microcirculation-myocyte interface. In this study, we hypothesized that increasing muscle microva...

Development of a new SonovueTM contrast-enhanced ultrasound approach reveals temporal and age-related features of muscle microvascular responses to feeding (2013)
Journal Article

Development of a new SonovueTM contrast-enhanced ultrasound approach reveals temporal and age-related features of muscle microvascular responses to feeding. Physiological Reports, 1(5), Article e00119. https://doi.org/10.1002/phy2.119

Compromised limb blood flow in aging may contribute to the development of sarcopenia, frailty, and the metabolic syndrome. We developed a novel contrast-enhanced ultrasound technique using Sonovue™ to characterize muscle microvasculature responses to...

Effects of leucine and its metabolite β-hydroxy-β-methylbutyrate on human skeletal muscle protein metabolism (2013)
Journal Article

Maintenance of skeletal muscle mass is contingent upon the dynamic equilibrium (fasted losses–fed gains) in protein turnover. Of all nutrients, the single amino acid leucine (Leu) possesses the most marked anabolic characteristics in acting as a trig...
