An ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat). It can refer to the cardiac atrium , [ 1 ] cardiac ventricle , [ 2 ] gall bladder, [ 3 ] or leg veins, [ 4 ] although if unspecified it usually refers to the ...
Left-sided heart failure may be present with a reduced ejection fraction or with a preserved ejection fraction. [10] Heart failure is not the same as cardiac arrest, in which blood flow stops completely due to the failure of the heart to pump. [12] [13] Diagnosis is based on symptoms, physical findings, and echocardiography. [6]
The cause of cirrhosis can vary; alcohol and non-alcoholic fatty liver disease are main causes in western and industrialized countries, whereas viral hepatitis is the predominant cause in low and middle-income countries. [156] Cirrhosis is more common in men than in women. [158]
Gallbladder cancer is a relatively uncommon cancer, with an incidence of fewer than 2 cases per 100,000 people per year in the United States. [7] It is particularly common in central and South America, central and eastern Europe, Japan and northern India; it is also common in certain ethnic groups e.g. Native American Indians and Hispanics.

The conditions of the earlier stages are 8% ethanol, pH 7.2, −3 °C, and 5.1% protein for Fraction I; 25% ethanol, pH of 6.9, −5 °C, and 3% protein. The albumin remains in the supernatant fraction during the solid/liquid separation under these conditions. Fraction IV has several unwanted proteins that need to be removed.
The higher number (about 40%) commonly reported refers to collisions defined as alcohol-related as estimated by the National Highway Traffic Safety Administration. Each year, The Century Council, a national non-profit organization funded by a group of alcohol manufacturers, compiles a document of alcohol-related traffic fatalities. Between 1991 ...

Alcohol by volume (abbreviated as alc/vol or ABV) is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage, expressed as a volume percent. [ 1 ] [ 2 ] [ 3 ] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F).
