Study IDST000165
Study TitleSparing of muscle mass and function by passive loading in an experimental intensive care unit model
Study Typetime course + intervention
Study SummaryA unique experimental rat ICU model has been used allowing long-term (weeks) time-resolved analyses of the effects of standardized unilateral passive mechanical loading on skeletal muscle size and function and underlying mechanisms. Results show that passive mechanical loading alleviated the muscle wasting and the loss of force-generation associated with the ICU intervention, resulting in a doubling of the functional capacity of the loaded versus the unloaded muscles after a 2-week ICU intervention.

Chromatography Summary:The level of enrichment of [ring-13C6]phenylalanine derived from hydrolysed mixed muscle proteins were analysed using a ThermoFisher DeltaPlus Isotope Ratio mass spectrometer (IR/MS) (Bremen, Germany) fitted with an on-line gas chromatograph with oxidation and reduction furnaces as previously described (Balagopal et al. 1996). The amino acids were derivatized to their trimethyl acetyl, methyl esters according to the method of Metges et al. (1996). Any amino acid eluting from the gas chromatograph is converted to CO2 and N2 prior to entry into the IR/MS. The amino acids were derivatized to their trimethyl acetyl, methyl esters according to the method of Metges et al. (1996). Enrichment of the tracer was measured by monitoring the ratio of 13C to 12CO2 in the IR/MS and again referenced to a calibration curve (00.1%).
