Unlike plants, fungi cannot synthesize their own food using energy from the sun. Instead, they must draw their food from a source--sometimes a tree. Fungi extend fibers into the host plant, absorbing its nutrients and depleting its energy, causing the tree to decline.
Hydroxyzine (/haÉªËdrÉksÉ¨ziËn/ ; sold as Vistaril, Atarax) is a first-generation antihistamine of the diphenylmethane and piperazine class.It was first synthesized by Union Chimique Belge in 1956 and was marketed by Pfizer in the United States later the same year, and is still in widespread use today.ydroxyzine's predominant mechanism of action is as a potent H1 receptor inverse agonist (K i = 2 nM). Unlike many other first-generation antihistamines, it has very low affinity for the mACh receptors (K i and in accordance, has a low propensity for producing anticholinergic side effects.
An article in your April issue, Common drugs linked to dementia, states that anticholinergics are used to treat depression. I wasn't aware of this. Which types of anticholinergics are used for depression? A. We should have been clearer in our description of the medications. Anticholinergic drugs work by blocking the effects of acetylcholine, a substance that transmits messages in the nervous system. In the brain, acetylcholine is involved in learning and memory. In the rest of the body, it stimulates muscle contractions. A wide range of drugsâincluding tricyclic antidepressants like amitriptyline (Elavil) or doxepin (Deptran, Silenor, Sinequan)âhave strong anticholinergic effects, which means they can have side effects like memory problems and confusion.
