Latest Reactive oxygen species Stories
By Dan, Yinghui Abstract Browning and necrosis of transformed cells/ tissues, and difficulty to regenerate transgenic plants from the transformed cells/tissues (recalcitrance) are common in Agrobacterium-mediated transformation process in many plant species.
By Grand Forks Herald, N.D. Aug. 6--By Tom Johnson Why do we eat? This seems like a simple question. But when I asked several people, I received a variety of answers: "To nourish my body" or "because I'm hungry" and some far-out answers loosely related to the cosmos and our place in the universe.
Synta Pharmaceuticals Corp., (NASDAQ: SNTA) a biopharmaceutical company focused on discovering, developing, and commercializing small molecule drugs to treat severe medical conditions, today announced that it is appointing Michael P. Bailey Senior Vice President and Chief Commercial Officer. Mr.
Researchers showed for the first time that a natural antioxidant found in grape skins and red wine can help destroy cancer cells by reaching to the cell's core energy source, or mitochondria, and crippling its function.
By Corbin, Joseph F III; Teel, Amy L; Allen-King, Richelle M; Watts, Richard J ABSTRACT: The enhanced treatment of sorbed contaminants has been documented in modified Fenton's reactions; contaminants are desorbed and degraded more rapidly than they desorb by fill-and-draw or gas- purge desorption.
Some may be surprised to learn that bleach-blondes and the enabler of life elsewhere in our solar system have something in common. And, no, it's not intelligence. It is, in fact, hydrogen peroxide.
Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cell's ability to detoxify harmful reactive oxygen species. The research appears as the "Paper of the Week" in the November 11 issue of the Journal of Biological Chemistry, an American Society for Biochemistry and Molecular Biology journal.
Three studies in the June issue of Cell Metabolism offer additional insight into how the cells of mammals sense oxygen. Oxygen plays a central role in fueling cells, and oxygen deficiency underlies many disease conditions, including heart attack, stroke, inflammation, and cancer. The findings should help to resolve a long-standing controversy over the identity of mammalian oxygen sensors, according to the researchers.
Researchers have produced the strongest evidence yet that mitochondria â€” the organelles that generate energy to power the cell â€” also monitor oxygen concentration in the cell. If oxygen slips below a critical threshold, the mitochondrial â€œsensorâ€ triggers protective responses to promote survival.
