(20) When detergent-dispersed LA was contaminated with linoleic acid hydroperoxide (LOOH), lipid peroxidation was catalyzed by Fe2+ via reductive cleavage of LOOH (LOOH-Fe2+-induced lipid peroxidation), and Fe2+ was oxidized simultaneously in SDS micelles, even when H2O2 was not present.
Radiation
Definition:
(n.) The act of radiating, or the state of being radiated; emission and diffusion of rays of light; beamy brightness.
(n.) The shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of heat.
Example Sentences:
(1) Recently, it has been shown that radiation therapy, alone or combined with chemotherapy, can be successful.
(2) Sixteen patients were operated on for lumbar pain and pain radiating into the sciatic nerve distribution.
(3) Because of the small number of patients reported in the world literature and lack of controlled studies, the treatment of small cell carcinoma of the larynx remains controversial; this retrospective analysis suggests that combination chemotherapy plus radiation offers the best chance for cure.
(4) Breast conserving surgery in patients with small tumors combined with radiation therapy has gained wide popularity due to better cosmetic results without significant changes in survival.
(5) A Monte Carlo simulation was performed to characterize the spatial and energy distribution of bremsstrahlung radiation from beta point sources important to radioimmunotherapy (RIT).
(6) While both inhibitors caused thermosensitization, they did not affect the time scale for the development of thermotolerance at 42 degrees C or after acute heating at 45 degrees C. The inhibitors of poly(ADP-ribosylation) radiosensitizers and thermosensitizers may be of use in the treatment of cancer using a combined modality of radiation and hyperthermia.
(7) 11 patients with a postoperative classification of stage D had additional external beam radiation to the pelvic and paraaortic lymph nodes with shielding of the implanted prostatic region.
