- UAL
UAL stands for ultrasonic-assisted liposuction. Liposuction involves the surgical suctioning of fat deposits from specific parts of the body, the most common being the abdomen (the “tummy”), buttocks (“behind”), hips, thighs and knees, chin, upper arms, back, and calves. Liposuction breaks up and “sucks” fat out of the body. This is done through a cannula […]
- Ubiquitin
A small but extremely important protein that acts the “kiss of death” to other proteins. Ubiquitin consists of only 76 amino acids. In the normal course of events, proteins are inactivated by the attachment of ubiquitin to them, a process called ubiquitination. Ubiquitin acts as a tag by which the protein-transport machinery ferries a protein […]
- Ubiquitous
Present everywhere. The small protein called ubiquitin was so-named because it is present in all types of cells and its amino acid sequence is identical in all creatures from insects to humans.
- UDP-glucuronosyltransferase
A liver enzyme essential to the disposal of bilirubin (the chemical that results from the normal breakdown of hemoglobin from red blood cells). An abnormality of this enzyme (UDP-glucuronosyltransferase) results in a condition called Gilbert’s disease in which there are mild elevations of bilirubin pigment in the blood. The elevated bilirubin pigment can sometimes cause […]
