Massive increase in radical species can lead to oxidative stress, promoting cell injury and
death. This review focuses on experimental evidence of oxidative stress in critical illnesses …

The association between physical exercise and oxidative damage in the skeletal
musculature has been the focus of many studies in literature, but the balance between …

The assessment of oxidative stress, defined as the association between an increased
production of oxygen-derived species and an exhaustion of the stores of antioxidants …

This study was designed to clarify whether mitochondrial function/dysfunction and reactive
oxygen species (ROS) production have a temporal relationship with organ failure during …

mRNA profiling has been extensively used to study muscle wasting. mRNA level changes
may not reflect that of proteins, especially in catabolic muscle where there is decreased …

Oxidant/antioxidant imbalance plays an important role in septic shock. The present study
examined changes in circulating oxidative components in a neonatal sepsis model. Subjects …

Introduction Aging is associated with a decline in cardiac contractility and altered immune
function. The aim of this study was to determine whether aging alters endotoxin-induced …

OBJECTIVES: To develop a standardized bacteraemic porcine model of septic shock with
cardiovascular and immunological profiles similar to those observed in human clinical …
