| isotone |
Two nuclides are isotones if they have the same number of neutrons.This is to be contrasted with:* Isotopes are nuclides having the same number of protons* Isobars are nuclides having the same mass number, i.e. sum of protons plus neutrons; see isobar for the meaning as on a weather chart.* Nuclear isomers are different excited states of the same type of nucleus. ...

| ischemic heart disease |
Coronary heart disease (CHD), also called coronary artery disease (CAD) and atherosclerotic heart disease, is the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium (the muscle of the heart). While the symptoms and signs of coronary heart disease are noted in the advanced state of disease, most individuals with coronary heart disease would have evidence of disease decades before the first symptoms arise. ...

| isolysergic acid |
Lysergic acid, also known as D-lysergic acid and (+)-lysergic acid, is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and some plants. Amides of lysergic acid, commonly called lysergamides, are widely used as pharmaceuticals and as hallucinogenic drugs (LSD). Lysergic acid is usually produced by hydrolysis of lysergamides, but can also be synthesized in the laboratory by a complex total synthesis. ...

| ischemic stroke |
A stroke or cerebrovascular accident (CVA) occurs when the blood supply to a part of the brain is suddenly interrupted by occlusion (an ischemic stroke- approximately 90% of strokes), by hemorrhage (a hemorrhagic stroke - less than 10% of strokes) or other causes. Ischemia is a reduction of blood flow most commonly due to occlusion (an obstruction). ...

| isolecithal |
Isolecithal (Greek iso = equal, lekithos = yolk) is the even distribution of yolk in the cytoplasm of ovums of mammals and other invertebrates notably Petromyzontidae, Acipenseridae, Amiidae, and Lepisosteidae. Isoleithal cells have two equal hemispheres of yolk. However during cellular development, normally under the influence of gravity, some of the yolk does settle to the bottom of the egg producing an uneven distribution of yolky hemispheres. ...
