Moving average crossover of a 15-day exponential close-price MA (red) crossing over a 50-day exponential close-price MA (yellow) In the statistics of time series, and in particular the stock market technical analysis, a moving-average crossover occurs when, on plotting two moving averages each based on different degrees of smoothing, the traces of these moving averages cross.
Dimethoxyamphetamine (DMA) is a series of six lesser-known psychedelic drugs similar in structure to the three isomers of methoxyamphetamine and six isomers of trimethoxyamphetamine. The isomers are 2,3-DMA, 2,4-DMA, 2,5-DMA , 2,6-DMA, 3,4-DMA, and 3,5-DMA.
[1] [2] [3] However, EC 50 values for monoamine release by 4-MTDMA were not reported. [ 2 ] [ 3 ] 4-MTDMA is a partial releaser of serotonin rather than a full releaser, with a maximal efficacy for induction of serotonin release of either 25% or 50% relative to the full serotonin releasers MDMA or para -chloroamphetamine (PCA).
For example, the 50-day moving average represents the stock’s average price over the past 50 days of trading. In the case of the 200-day moving average, it shows the stock’s average closing ...
2,5-DMA is a low-potency serotonin 5-HT 2A receptor partial agonist, with an affinity (K i) of 2,502 nM, an EC 50 Tooltip half-maximal effective concentration of 160 to 2,352 nM (depending on the signaling cascade), and an E max Tooltip maximal efficacy of 66%. [3] It has also been assessed at several other receptors. [3]
DMA was first reported in 1850 by the German chemist A. W. Hofmann, who prepared it by heating aniline and iodomethane: [3] [4] C 6 H 5 NH 2 + 2 CH 3 I → C 6 H 5 N(CH 3) 2 + 2 HI. DMA is produced industrially by alkylation of aniline with methanol in the presence of an acid catalyst: [5] C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2 H 2 O
Methyl-DMA (2,5-dimethoxy-N-methylamphetamine) is a lesser-known psychedelic drug and substituted methamphetamine. It was first synthesized by Alexander Shulgin. In his book PiHKAL, the minimum dosage is listed as 250 mg, and the duration unknown. [1] Methyl-DMA produces slight paresthesia. Very little data exists about the pharmacological ...
HLA class II histocompatibility antigen, DM alpha chain is a protein that in humans is encoded by the HLA-DMA gene. [5] [6] HLA-DMA belongs to the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DMA) and a beta chain (DMB), both anchored in the membrane. It is located in intracellular vesicles.
