Quinine total synthesis: 400px|right|quinine carbon atom numbering scheme left and asymmetric centers rightQuinidineCrampTaste: Taste, gustatory perception, or gustationAdjectival form: [is the sensory impression of food] or other substances on the tongue and is one of the [[sense|five traditional senses.Exploding head syndrome: Exploding head syndrome (EHS) is a condition in which a person hears loud noises (such as a bomb exploding, a gunshot, or a cymbal crash) or experiences an explosive feeling when falling asleep or waking up. These noises have a sudden onset, are typically brief in duration, and are often jarring for the sufferer.MefloquinePfATP6: PfATP6, also known as PfSERCA or PfATPase6, is a calcium ATPase gene encoded by the malaria parasite Plasmodium falciparum. The protein is thought to be a P-type ATPase involved in calcium ion transport.Cinchona officinalis: Cinchona officinalis, the Quinine Bark tree Qinchona · , is a South American tree, native to Amazon Rainforest plant community.CinchonismSesquiterpene lactone: Sesquiterpene lactones are a class of chemical compounds; they are sesquiterpenoids (built from three isoprene units) and contain a lactone ring, hence the name. They are found in many plants and can cause allergic reactions and toxicity if overdosed, particularly in grazing livestock.ChloroquinePregnancy-associated malaria: Pregnancy-associated malaria (PAM) or placental malaria is a presentation of the common illness that is particularly life-threatening to both mother and developing fetus. PAM is caused primarily by infection with Plasmodium falciparum, the most dangerous of the four species of malaria-causing parasites that infect humans.Iferanserin: Iferanserin (INN; VEN-309) is a drug which acts as a selective 5-HT2A receptor antagonist. It is under development as an intra-rectal formulation for the treatment of hemorrhoid disease, and as of February 2012, is in phase IIb clinical trials.Chorda tympani: The chorda tympani is a branch of the facial nerve that originates from the taste buds in the front of the tongue, runs through the middle ear, and carries taste messages to the brain. It joins the facial nerve (cranial nerve VII) inside the facial canal, at the level where the facial nerve exits the skull via the petrotympanic fissure.TizanidineBranch of glossopharyngeal nerve to carotid sinus: The branch of glossopharyngeal nerve to the carotid sinus (Hering's nerve) is a small nerve in the neck, that innervates the carotid sinus and the carotid body.Sucrose gap: The sucrose gap technique is used to create a conduction block in nerve or muscle fibers. A high concentration of sucrose is applied to the extracellular space to increase resistance between two groups of cells, which prevents the correct opening and closing of sodium and potassium channels.
