Bilirubin: from an unimportant waste product to important myocardial infarction predictor
Abstract:
Bilirubin is the major catabolic product of heme degradation. It has long been regarded as an unimportant waste product. However, within the last twenty-five years, it has been demonstrated to play a very important role in maintaining the bodys redox equilibrium. Disturbances of this equilibrium - increased oxidative stress - are currently considered one of the major risk factors for the development of non-communicable diseases. Although the exact mechanism is not known, a number of human studies have proved a reduced incidence of a number of (especially cardiovascular but also cancer) diseases in individuals with mildly elevated bilirubin concentrations. Key words: bilirubin - cardiovascular disease - morbidity - mortality.

Dot Product
In engineering, the dot product of any two vectors is the product of the magnitudes of the vectors and the cosine of the angle between them. It is denoted by a dot symbol between the two vectors.
Consider a vehicle pulling an object along the ground using a rope. If the rope makes an angle with the horizontal axis, the work done can be calculated using the dot product of the force applied and the object's displacement.
The dot...
