Methylene blue has been used clinically for over a century, but its association with serotonin toxicity has just been elucidated in the last decade. Two surgical case series from 2006 and 2007 describe methylene-blue associated CNS toxicity in patients receiving intraoperative methylene blue.
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.This is a type of greenhouse effect.lobal Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases. Without the greenhouse effect, Earthâs temperature would be below freezing.It is, in part, a natural process.However, Earthâs greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. Thatâs is warming the climate of our planet.he greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases.
