Mechanical ventilation with large tidal volumes can increase lung alveolar permeability and initiate inflammatory responses, termed ventilator-induced lung injury (VILI). VILI is characterized by an influx of inflammatory cells, increased pulmonary permeability, and endothelial and epithelial cell death. But the underlying molecular mechanisms that regulate… (More)
The protective effect of hydrogen (H(2)) on ROS-induced diseases has been proved by many researches, which demonstrated that through eliminating •OH and •ONOO-, H(2) could effectively attenuate lipid and DNA peroxidation, improve cellular antioxidant capacity, and then protect cells against oxidant damage. Most of free radicals in human body are ROS,… (More)
In recent years, hyperbaric oxygen (HBO) has been used in the treatment of a lot of diseases such as decompression sickness, arterial gas embolism, carbon dioxide poisoning, soft tissue infection, refractory osteomyelitis, and problematic wound, but little is known about its application in liver transplantation. Although several studies have been conducted… (More)
Hyperoxic acute lung injury (HALI) refers to the damage to the lungs secondary to exposure to elevated oxygen partial pressure. HALI has been a concern in clinical practice with the development of deep diving and the use of normobaric as well as hyperbaric oxygen in clinical practice. Although the pathogenesis of HALI has been extensively studied, the… (More)
A three-stage-structured prey-predator system with predator density dependent time delay is considered. The positive and uniformly bounded of the solution of the system are obtained, and the conditions for the system occurring global Hopf bifurcation is given. Finally, numerical simulations and brief conclusion are given.
