This retention may be a cause, an effect, or both, of the underlying inflammatory process.The presence of the plaque induces the muscle cells of the blood vessel to stretch, compensating for the additional bulk. The endothelial lining then thickens, increasing the separation between the plaque and lumen. The thickening somewhat offsets the narrowing caused by the growth of the plaque, but moreover, it causes the wall to stiffen and become less compliant to stretching with each heartbeat. Modifiable

Dietary
The relation between dietary fat and atherosclerosis is controversial. The USDA, in its food pyramid, promotes a diet of about 64% carbohydrates from total calories. The American Heart Association,  the American Diabetes Association and the National Cholesterol Education Program make similar recommendations. In contrast, Prof Walter Willett (Harvard School of Public Health, PI of the second Nurses Health Study) recommends much higher levels of fat, especially of monounsaturated and polyunsaturated fat. These dietary recommendations reach a consensus, though, against consumption of trans fats.The role of eating oxidized fats (rancid fats) in humans is not clear. Rabbits fed rancid fats develop atherosclerosis faster. Rats fed DHA-containing oils experienced marked disruptions to their antioxidant systems, and accumulated significant amounts of phospholipid hydroperoxide in their blood, livers and kidneys.Rabbits fed atherogenic diets containing various oils were found to undergo the most oxidative susceptibility of LDL via polyunsaturated oils.
The median palatal cyst is a rare cyst that may occur anywhere along the median palatal raphe. It may produce swelling because of infection and is treated by excision or surgical removal. Some investigators now believe that this cyst represents a more posterior presentation of a nasopalatine duct cyst, rather than a separate cystic degeneration of epithelial rests at the line of fusion of the palatine shelves.
