In the 2005 TNT study, 10,001 people with stable heart disease received either maximum-dose 80-mg LipitorÂ® or a standard dose of 10-mg LipitorÂ® daily. 1 Maximum-dose LipitorÂ® reduced levels of harmful low density lipoprotein (LDL) to an average of 77 mg/dL.This represented a substantial reduction in LDL.In comparison, standard-dose LipitorÂ® reduced LDL to an average level of 101 mg/dL, which was also a good result.

The units of a ribosome are often described by their Svedberg (s) values, which are based upon their rate of sedimentation in a centrifuge. The ribosomes in a eukaryotic cell generally have a Svedberg value of 80S and are comprised of 40s and 60s subunits. Prokaryotic cells, on the other hand, contain 70S ribosomes, each of which consists of a 30s and a 50s subunit.
A. Structure and Composition. Ribosomes are composed of ribosomal RNA (rRNA) and protein. Prokaryotic cells have three types of rRNA: 16S rRNA, 23S rRNA, and 5S rRNA. Like transfer RNA (tRNA), rRNAs use intrastrand H-bonding between comlementary nucleotide bases to form complex folded structures.. Bacterial ribosomes are composed of two subunits with densities of 50S and 30S, as opposed to 60S and 40S in eukaryotic cells. 3. Ribosomes function as a workbench for protein synthesis whereby they receive and translate genetic instructions for the formation of specific proteins. 4.
