Intensified training increases salivary free light chains in trained cyclists
Jennifer L.J. Heaney, Sophie C. Killer, Ida S. Svendsen, Michael Gleeson, John P. Campbell
May 01, 2018
Periods of short-term intensified training (IT) are often used by athletes during training cycles over the season and undergoing phases of increased physical stress may impact upon the immune system. This study investigated...

Negative Psychological Experiences and Saliva Secretory Immunoglobulin A in Field Hockey Players
Understanding psychological factors that affect immunity in sport might help to reduce infection risk in athletes. The present study examined within-person changes and individual differences in perceived coach control...
Effect of Mesh Quality on Flux Reconstruction in Multi-dimensions
Theoretical methods are developed to understand the effect of non-uniform
grids on Flux Reconstruction (FR) in multi-dimensions. The analysis reveals
that the same effect of expanding and contracting grids is seen in...
Increased ICP and Its Cerebral Haemodynamic Sequelae.
Joseph Donnelly, Marek Czosnyka, Spencer Harland, Georgios V Varsos, Danilo Cardim, Chiara Robba, Xiuyun Liu, Philip N Ainslie, Peter Smielewski
May 22, 2018
OBJECTIVES: Increased intracranial pressure (ICP) is a pathological feature of many neurological diseases; however, the local and systemic sequelae of raised ICP are incompletely understood. Using an experimental paradigm, we...

Effect of Mesh Quality on Flux Reconstruction in Multi-dimensions
Abstract: Theoretical methods are developed to understand the effect of non-uniform grids on Flux Reconstruction (FR) in multi-dimensions. A better theoretical understanding of the effect of wave angle and grid deformation is...

Natural variation in tolerance to sub-zero temperatures among populations of Arabidopsis lyrata ssp. petraea.
Matthew P Davey, Ben G Palmer, Emily Armitage, Philippine Vergeer, William E Kunin, F Ian Woodward, W Paul Quick
Feb 11, 2019
BACKGROUND: Temperature is one of the most important abiotic factors limiting plant growth and productivity. Many plants exhibit cold acclimation to prepare for the likelihood of freezing as temperatures decrease towards 0 °C....

Nov 11, 2019
BACKGROUND: In traumatic brain injury (TBI) the patterns of intracranial pressure (ICP) waveforms may reflect pathological processes that ultimately lead to unfavorable outcome. In particular, ICP slow waves (sw) (0.005-0.05 Hz)...
