Pneumocystis carinii cell wall beta-glucans initiate macrophage inflammatory responses through NF-kappaB activation.

beta-Glucans are major structural components of fungi. We have recently reported that the pathogenic fungus Pneumocystis carinii assembles a beta-glucan-rich cell wall that potently activates alveolar macrophages to release pro-inflammatory cytokines and chemokines. Purified P.

Patient anesthesia and monitoring at a 1.5-T MRI installation.

This paper describes the facilities successfully used to provide patient monitoring and anesthesia support in a 1.5-T imaging installation. The requirements for the MRI site for anesthetic gases, shielded power, and radiofrequency ports are outlined.
