Adrenochrome is a chemical compound produced by the oxidation of adrenaline (epinephrine). It was the subject of limited research from the 1950s through to the 1970s as a potential cause of schizophrenia.
American citizens who had checked into hospitals for a variety of ailments were secretly injected, without their knowledge, with varying amounts of plutonium and other radioactive materials. Ebb Cade was an unwilling participant in medical experiments that involved injection of 4.7 micrograms of plutonium on 10 April 1945 at Oak Ridge, Tennessee.
3,4-Dihydroxyphenylacetaldehyde (DOPAL), also known as dopamine aldehyde, is a metabolite of the monoamine neurotransmitter dopamine formed by monoamine oxidase (MAO). [ 2 ] [ 3 ] Other metabolic pathways of dopamine metabolism include methylation by catechol O -methyltransferase (COMT) into 3-methoxytyramine and β-hydroxylation by dopamine β ...
In 1946, six employees of a Chicago metallurgical lab were given water that was contaminated with plutonium-239 so that researchers could study how plutonium is absorbed into the digestive tract. [71] An eighteen-year-old woman at an upstate New York hospital, expecting to be treated for a pituitary gland disorder, was injected with plutonium. [78]
MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is an organic compound.It is classified as a tetrahydropyridine.It is of interest as a precursor to the monoaminergic neurotoxin MPP +, which causes permanent symptoms of Parkinson's disease by destroying dopaminergic neurons in the substantia nigra of the brain.
The medication phentolamine can be given to try to decrease this risk. [4] It is unclear if dopamine is safe to use during pregnancy or breastfeeding. [4] At low doses dopamine mainly triggers dopamine receptors and β1-adrenergic receptors while at high doses it works via α-adrenergic receptors. [4]
In a follow-up memory test administered the morning after Semax administration, the treatment group made more correct responses (71%) than the control group (41%). [ 14 ] A 2018 study involving 110 patients recovering from ischemic stroke reported increases in brain-derived neurotrophic factor (BDNF) (correlated with early rehabilitation) in ...
Magnetic implants, however, often contain a substantial amount of metallic elements by volume, and iron, a common implant element, is easily corroded by common elements such as oxygen and water. Implant corrosion occurs when these elements become trapped inside during the encapsulation process, which can cause slow corrosive effect, or the ...
