3-Indolepropionic acid (IPA), or indole-3-propionic acid, has been studied for its therapeutic value in the treatment of Alzheimer's disease. As of 2022 [ 3 ] IPA shows potential in the treatment of this disease, though the therapeutic effect of IPA depends on dose and time of therapy initiation.

Other symbols are unique to the IPA, and have developed their own quirky names: ɾ fish-hook r, ɤ ram's horns, ʘ bull's eye, ʃ esh (apparently never 'stretched s'), ʒ ezh (sometimes confused with yogh), ɧ hook-top heng. The ʔ is usually called by the sound it represents, glottal stop. This is not normally a problem, because this symbol is ...
Several claims have been made for doubly articulated fricatives or affricates, most notoriously a Swedish phoneme which has its own IPA symbol, . However, laboratory measurements have never succeeded in demonstrating simultaneous frication at two points of articulation, and such sounds turn out to be either secondary articulation, or a sequence ...
Interpretative phenomenological analysis (IPA) is a qualitative form of psychology research. IPA has an idiographic focus, which means that instead of producing generalization findings, it aims to offer insights into how a given person, in a given context, makes sense of a given situation. Usually, these situations are of personal significance ...

The triple response of Lewis is due to the release of histamine. Histamine, or 2-(imidazol-4-yl)ethanamine, is a dibasic vasoactive amine that is located in most body tissues but is highly concentrated in the lungs, skin, and gastrointestinal tract. Histamine is a small molecule, stored in granules of mast cells and basophils. Mast cells and ...
The triple-alpha process is a set of nuclear fusion reactions by which three helium-4 nuclei (alpha particles) are transformed into carbon. [1] [2]
