Human Skeletal Muscle Protein Metabolism Responses to Amino Acid Nutrition (2016)
Journal Article
Mitchell, W. K., Wilkinson, D. J., Phillips, B. E., Lund, J. N., Smith, K., & Atherton, P. J. (2016). Human Skeletal Muscle Protein Metabolism Responses to Amino Acid Nutrition. Advances in Nutrition, 7(4), 828S-838S. https://doi.org/10.3945/an.115.011650

Healthy individuals maintain remarkably constant skeletal muscle mass across much of adult life, suggesting the existence of robust homeostatic mechanisms. Muscle exists in dynamic equilibrium whereby the influx of amino acids (AAs) and the resulting... Read More about Human Skeletal Muscle Protein Metabolism Responses to Amino Acid Nutrition.

Background The aims of this study were to determine if patient ASA grade was associated with increased stress in anaesthetists with a subsequent effect on non-technical skills. Methods Stress was measured using a validated objective (heart rat... Read More about Anaesthetists stress is induced by patient ASA grade and may impair non-technical skills during intubation.

Day-case closure of ileostomy: feasible, safe and efficient (2015)
Journal Article
Bhalla, A., Peacock, O., Tierney, G., Tou, S., Hurst, N., Speake, W., …Lund, J. N. (2015). Day-case closure of ileostomy: feasible, safe and efficient. Colorectal Disease, 17(9), https://doi.org/10.1111/codi.12961

Aim Over 5000 loop ileostomy closures were performed in the UK in 2013 with a median inpatient stay of 5 days. Previously we have successfully implemented a 23-h protocol for loop ileostomy closure which was modified for same-day discharge. We pre...

Internal comparison between deuterium oxide (D2O) and L-[ring-13C6] phenylalanine for acute measurement of muscle protein synthesis in humans (2015)
Journal Article

Stable isotope tracer methodologies are becoming increasingly widespread in metabolic research; yet a number of factors restrict their implementation, such as, i.v infusions, multiple cannulae, tissue samples, and significant cost. We recently valida... Read More about Internal comparison between deuterium oxide (D2O) and L-[ring-13C6] phenylalanine for acute measurement of muscle protein synthesis in humans.

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,...

Assessing surgeon stress when operating using heart rate variability and the State Trait Anxiety Inventory: will surgery be the death of us? (2015)
Journal Article
Jones, K., Amawi, F., Bhalla, A., Peacock, O., Williams, J. P., & Lund, J. N. (2015). Assessing surgeon stress when operating using heart rate variability and the State Trait Anxiety Inventory: will surgery be the death of us?. Colorectal Disease, 17(4), https://doi.org/10.1111/codi.12844

Aim Performance in the operating room is affected by a combination of individual, patient and environmental factors amongst others. Stress has a potential negative impact on performance with the quality of surgical practice and patient safety bein...

Simple psoas cross-sectional area measurement is a quick and easy method to assess sarcopenia and predicts major surgical complications (2014)
Journal Article
Jones, K., Doleman, B., Scott, S., Lund, J. N., & Williams, J. P. (2015). Simple psoas cross-sectional area measurement is a quick and easy method to assess sarcopenia and predicts major surgical complications. Colorectal Disease, 17(1), Article O20-O26. https://doi.org/10.1111/codi.12805

Aim Radiologically assessed muscle mass has been suggested as a surrogate marker of functional status and frailty and may predict patients at risk of postoperative complications. We hypothesize that sarcopenia negatively impacts on postoperative r...

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...

One-third of patients fail to return to work 1 year after surgery for colorectal cancer (2014)

Background Achieving full recovery after colorectal cancer surgery means a return to normal physical and psychological health and to a normal social life. Recovery data focusses on time to discharge rather than longer term functionality including...

Journal Article
Cruickshanks, H., Vafadar-Isfahani, N., Dunican, D., Lee, A., Sproul, D., Lund, J. N., …Tufarelli, C. Expression of a large LINE-1-driven antisense RNA is linked to epigenetic silencing of the metastasis suppressor gene TFPI-2 in cancer. Nucleic Acids Research, 41(14), https://doi.org/10.1093/nar/gkt438

LINE-1 retrotransposons are abundant repetitive elements of viral origin, which in normal cells are kept quiescent through epigenetic mechanisms. Activation of LINE-1 occurs frequently in cancer and can enable LINE-1 mobilization but also has re...
