A mixture of liquids with different boiling points like water and ethanol or crude oil which is a mixture of hydrocarbons. It can also be used to separate a solution into its â¦ solvent and solute, for example salt solution (salt water) could be separated into water (solvent) and salt (solute).
Most of our success in understanding the genetic basis of common forms of atherosclerosis has come from studies of âcandidate genes,â genes identified by biochemists and subsequently examined for genetic differences and associations in populations. A good example of a candidate gene is apolipoprotein E (apoE).
Atherosclerosis is the hardening and narrowing of the arteries due to the buildup of a waxy substance called plaque (plak). Rarely, infectionsâsuch as untreated syphilis (a sexually transmitted infection)âcan cause aortic aneurysms. Aortic aneurysms also can occur as a result of diseases that inflame the blood vessels, such as vasculitis (vas-kyu-LI-tis). A family history of aneurysms also may play a role in causing aortic aneurysms. In addition to the factors above, certain genetic conditions may cause thoracic aortic aneurysms (TAAs). Examples of these conditions include Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome (the vascular type), and Turner syndrome.
