However, using lenses with a shorter focal length, he could, in effect, turn the telescope around and magnify little things. His first microscopes, in 1609, were basically little telescopes with the same two lenses: a bi …

WebHe coined the term metabolism for the chemical changes that take place in living tissue, identified the role played by microorganisms in putrefaction, and formulated the basic principles of embryology by observing that the egg is a single cell that eventually develops into a complete organism. WebCTCs were enriched using EpCAM antibody-conjugated magnetic beads. The number of CTCs was 0–30 and 0–54 in peripheral blood before and after TACE, respectively ( P =0.166), and 0–65 and 0–98 in the right atrium before and after TACE, respectively ( P =0.102). The number of CTCs was significantly different between the two samples both ...
