Lysosomal storage diseases (LSDs; / ˌ l aɪ s ə ˈ s oʊ m əl /) are a group of over 70 rare inherited metabolic disorders that result from defects in lysosomal function. [1] [2] Lysosomes are sacs of enzymes within cells that digest large molecules and pass the fragments on to other parts of the cell for recycling.
LSD is a potent psychoplastogen, a compound capable of promoting rapid and sustained neural plasticity that may have wide-ranging therapeutic benefit. [248] LSD has been shown to increase markers of neuroplasticity in human brain organoids and improve memory performance in human subjects. [249]
LSD made a comeback in the 1980s accompanying the advent of recreational MDMA use, first in the punk and gothic subcultures through dance clubs, then in the 1990s through the acid house scene and rave subculture. LSD use and availability declined sharply following a raid of a large scale LSD lab in 2000 (see LSD in the United States).
Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, [1] is a single-step multiple comparison procedure and statistical test.
The formula for the one-way ANOVA F-test statistic is =, or =. The "explained variance", or "between-group variability" is = (¯ ¯) / where ¯ denotes the sample mean in the i-th group, is the number of observations in the i-th group, ¯ denotes the overall mean of the data, and denotes the number of groups.
6-Isopropyl-6-nor-lysergic acid diethylamide (IP-LAD) is an analog of lysergic acid diethylamide (LSD) developed by the team of David E. Nichols.In studies on mice, it was found to be approximately 40% the potency of LSD, compared to the 60% increase in potency seen with ETH-LAD, 2-fold potency increase of AL-LAD, and roughly equivalent potency of PRO-LAD.
The log-spectral distance (LSD), also referred to as log-spectral distortion or root mean square log-spectral distance, is a distance measure between two spectra. [1] The log-spectral distance between spectra () and ^ is defined as p-norm:
LSD (d-Lysergic Acid Diethylamide) is a molecule of the lysergamide family, a subclass of the tryptamine family. In the 1950s, it was used in psychological therapy, and, covertly, by the CIA in Project MKULTRA , in which the drug was administered to unwitting US and Canadian citizens.
