GLUTAMATE AS NEUROTRANSMITTER. Glutamic acid (abbreviated as Glu or E) is one of the 20-22 proteinogenic amino acids, and its codons are GAA and GAG. It is a non-essential amino acid with a side chain carboxylic acid functional group. The carboxylate anions and salts of glutamic acid are known as glutamates.
The French scale or French gauge system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, Ga, FR or F. It may also be abbreviated as CH or Ch (for Charriere, charriÃ¨re its). Inventor The french = size 3 times the diameter in. millimeters round catheter of 1 French has an external diameter of 1â3 mm, and therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3: D (mm) = Fr / 3. or. Fr = D (mm) * 3. For example, if the French size is 9, the diameter is 3 mm.
FDG PET scan (coronal view).There is increased activity seen in the neck and shoulder muscles. Moderate uptake is also seen in the psoas muscles in this patient with scoliosis (arrows) [Image courtesy of Centre for Molecular Imaging, Peter MacCallum Cancer ...n summary; FDG will localise to any part of the body where there is high physiologic activity. Basic to the proper interpretation of PET CT scans is a clear understanding of the normal variants of uptake and awareness of the benign processes that are FDG avid to avoid potential pitfalls in image interpretation.
