trust me, you will know when it's bad. There are few things in this world that smell as bad as a rotten potato. It may also be slimy. Those 'barnacle things' are fine. The potato is a root, those things are just shoots. Rub them off and you'll be fine.
Malignant hyperthermia (MH) is a rare, inherited skeletal muscle syndrome that presents as a hypermetabolic reaction triggered by exposure to volatile anesthetic gases or the depolarizing muscle relaxant, succinylcholine. 1,2 The incidence of MH is difficult to quantify.
The MSH binds to a receptor on melanocyte skin cells called MC1R and makes these cells produce melanin, which darkens the skin. But researchers have been stumped by how sex hormones can enhance or lessen skin pigmentation, because neither estrogen nor progesterone works through MC1R.
