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.
A greenhouse gas (GHG) is any gas in the atmosphere that takes in (absorbs) and gives off (emits) radiation in the heat (infrared) wavelength range. Greenhouse gases cause the greenhouse effect, which results in increased temperatures on Earth.ut greenhouse gases in the atmosphere absorb some of the infrared radiation energy and âtrapâ it in the lower atmosphere. Less heat radiates into space, and the Earth is warmer. Many greenhouse gases occur naturally. Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earthâs atmosphere.
