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.
Ocean acidification-another effect of global warming. Fossil fuel combustion and industrial processes release over six billion metric tons of carbon into the atmosphere each year.ffects of global warming. It increases the atmosphere temperature, it causes acid rain, Some chemicals emitted by the greenhouse like Chloroflorcarbons breaks the OZON layer which absorps some dengeriouse electromagnatic rediation, so dengriouse electromagnatic rediations like UV (ultrovilat rediations), X-ray etc.
