Basics of the medical use of ayahuasca: physiology of dimethyltryptamine
Abstract:
Ayahuasca is a brew made of two admixture plants containing dimethyltryptamine (DMT) and b-carbolines (harmine and tetrahydroharmine). The indigenous groups of the Amazonas basin have been using it for centuries as an ethnomedical substance in healing and spiritual-religious rituals. During the last two decades the brew has raised increased scientific and public interest worldwide about its healing effects. Present paper addresses the therapeutic potentials of ayahuasca use and outlines the cellular mechanisms behind - in focus of the Q-1 receptor mediated action of DMT. The scientific investigation of ayahuasca is complicated by methodical problems, legal issues, and sociocultural pre-conceptions.

Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...
Basic Operations on Signals
Time Reversal mirrors a continuous-time signal about the vertical axis at t=0. This is achieved by substituting t with −t. For example, if a signal x(t) is considered, the time-reversed signal is x(−t). This operation can be graphically represented, showing the mirrored signal.

Length, which measures the distance traveled by an object, is a fundamental concept in engineering mechanics. We use coordinates relative to a reference point to describe the distance. Length not only helps to describe the...
