plaque definition biology

Plaque is a soft, sticky film that builds up on your teeth and contains millions of bacteria. Attack of Dental Plaque. plaque Source: Oxford Dictionary of Biochemistry and Molecular Biology Author(s): Richard CammackRichard Cammack, Teresa AtwoodTeresa Atwood, Peter CampbellPeter Campbell, Howard ParishHoward Parish, Anthony SmithAnthony … When you eat, the bacteria in plaque use the sugars in your food to produce acids that eat away at the tooth enamel. 25 In contrast, approximately 37% of women with AMI had plaque erosion, whereas in men erosion was present in only 18% (P=0.0004). Plaque rupture is also the predominant cause of death at autopsy, occurring in 75% of patients presenting with AMI (mean age, men=68±11, women=70±9 years) diagnosed by ECG and enzyme elevation. It is a proxy measurement rather than a measurement of the absolute quantity of particles: viral particles that are defective or which fail to infect their target cell will not produce a plaque and thus will not be counted. As plaque builds up, the wall of the blood vessel thickens. plaque meaning: 1. a flat piece of metal, stone, wood, or plastic with writing on it that is attached to a wall…. According to the landmark contribution of Farb et al. As shown above early atherosclerosis is mainly associated with the recruitment of inflammatory cells due to endothelium (tunica intima) damage. These deposits are made up of cholesterol, fatty substances, cellular waste products, calcium and fibrin (a clotting material in the blood). Plague definition, an epidemic disease that causes high mortality; pestilence. The bacteria in plaque cause tooth decay and gum disease if they are not removed regularly through brushing and flossing. in 1996, which reported that plaque erosion occurred in 44% of patients who died due to acute MI (with an increased prevalence in women), there has been no firm agreement on the precise prevalence of plaque erosion versus rupture (Figures 1 and 2). The next step is the formation of plaque … Plaque is a sticky film that forms on your teeth every day: You know, that slippery/fuzzy coating you feel when you first wake up. Dental plaque is a colorless, soft buildup of bacteria on your teeth, resulting in a 'fuzzy' feeling on the surface of each tooth. Plaque formation – Step 3 . Principle of Phage Plaque Assay. 2. deposits of cholesterol in artery walls that characterize arteriosclerosis. When a suspension of an infective phage (e.g. What is plaque? T4 phage) is spread over the lawn of susceptible bacterial cells (e.g. See more. Escherichia coli), the phage attaches the bacterial cell, replicate inside it, and kills it during its lytic release.Lysis of the bacteriophage is indicated by the formation of a zone of clearing or plaque within the lawn of bacteria. Atheroma’s or plaque build and can cause obstruction to the flow of blood within arteries. Learn more. This narrows the channel within the artery – reducing blood flow. plaques: n.pl 1. brain lesions found within the vacant areas between nerve cells. Plaque (fatty deposits) build up in your arteries is called atherosclerosis. A plaque-forming unit (PFU) is a measure used in virology to describe the number of virus particles capable of forming plaques per unit volume.
