Question: Consumption of which types of rice reduce the progression of atherosclerotic plaque development?
About the article "Rice", section "Nutrients and the nutritional importance of rice".

Candidate passages:
Lipoprotein Associated Phospholipase A2 has been identified and verified in multiple human trials as an enzymatic activity which is an independent predictor of atherosclerotic disease progression and events in humans, including coronary heart disease, because it promotes oxidation of lipoproteins and certain fatty acids.
It is available to physicians and patients as a blood test from multiple clinical labs, including LipoScience, and is commonly promoted as the PLAC test.
It does not actually measure or reflect the amount of atherosclerotic plaque present, only one factor affecting progression of existing atherosclerotic plaques.
As of 2009, there is no treatment for elevated levels of this enzymatic activity, though inhibitors are in development and clinical trials.
Thus currently it is only a marker which can serve as an indicator for more aggressive treatment of those physiologic behaviors which can be changed to slow/halt progression of atherosclerosis. 
Nutrition and health.
Nutrients and the nutritional importance of rice.
Rice is the staple food of over half the world's population.
It is the predominant dietary energy source for 17 countries in Asia and the Pacific, 9 countries in North and South America and 8 countries in Africa.
Rice provides 20% of the world’s dietary energy supply, while wheat supplies 19% and maize (corn) 5%.
A detailed analysis of nutrient content of rice suggests that the nutrition value of rice varies based on a number of factors.
It depends on the strain of rice, that is between white, brown, black, red and purple varieties of rice – each prevalent in different parts of the world.
It also depends on nutrient quality of the soil rice is grown in, whether and how the rice is polished or processed, the manner it is enriched, and how it is prepared before consumption.
An illustrative comparison between white and brown rice of protein quality, mineral and vitamin quality, carbohydrate and fat quality suggests that neither is a complete nutrition source.
Between the two, there is a significant difference in fiber content and minor differences in other nutrients.
Brilliantly colored rice strains, such as purple rice, derive their color from anthocyanins and tocols.
Scientific studies suggest that these color pigments have antioxidant properties that may be useful to human health.
In purple rice bran, hydrophilic antioxidants are in greater quantity and have higher free radical scavenging activity than lipophilic antioxidants.
Anthocyanins and γ-tocols in purple rice are largely located in the inner portion of purple rice bran.
Comparative nutrition studies on red, black and white varieties of rice suggest that pigments in red and black rice varieties may offer nutritional benefits.
Red or black rice consumption was found to reduce or retard the progression of atherosclerotic plaque development, induced by dietary cholesterol, in mammals.
White rice consumption offered no similar benefits, and the study claims this to be due to absent antioxidants in red and black varieties of rice.
Through cerebral angiography, the sign has been demonstrated to correspond to embolic or atherosclerotic occlusion of an artery.
Specifically, the hyperdensity is thought to be due to calcification or hemorrhage associated with an atherosclerotic plaque. 
Alvocidib (INN; also known as Flavopiridol or HMR-1275) is a flavonoid alkaloid CDK9 kinase inhibitor under clinical development for the treatment of chronic lymphocytic leukemia, by Sanofi.
It has been studied also for the treatment of arthritis and atherosclerotic plaque formation The target of Flavopiridol is the positive transcription elongation factor P-TEFb. 
Yellow softening is the third type of cerebral softening.
As its name implies, the affected softened areas of the brain have a yellow appearance.
This yellow appearance is due to atherosclerotic plaque build-up in interior brain arteries coupled with yellow lymph around the choroid plexus, which occurs in specific instances of brain trauma.
