Biomarkers, Creatine Kinase, and Kidney Function of Special Operation Candidates During Intense Physiological Training.

Introduction: The purpose of this pilot study was to assess for biomarkers indicative of passing intense physical training and establishing normative values within the tactical athlete population. Unfortunately, none of the biomarkers assessed were indicative of passing training, however, glucose, blood urea nitrogen, and creatine kinase (CK) levels stood out as abnormal. CK levels are commonly used in conjunction with muscle pain and/or myoglobinurea to diagnose exertional rhabdomyolysis (ER) in athletes and the military population.

Analysis of algorithms predicting blood:air and tissue:blood partition coefficients from solvent partition coefficients for prevalent components of JP-8 jet fuel.

Algorithms predicting tissue and blood partition coefficients (PCs) from solvent properties were compared to assess their usefulness in a petroleum mixture physiologically based pharmacokinetic/pharmacodynamic model. Measured blood:air and tissue:blood PCs for rat and human tissues were sought from literature resources for 14 prevalent jet fuel (JP-8) components. Average experimental PCs were compared with predicted PCs calculated using algorithms from 9 published sources.
