This video demonstrates the fluid dynamics of a flow cell…

This one shows a cell sorter (FACS – fluorescence activated cell sorting):

The next two animations show conjugated antibodies binding to antigens on a cell surface:

Minimal invasive treatment of hemorrhoids (Transanal Hemorrhoidal Dearterialization):

A doppler is used to locate branches of the hemorrhoidal arteries. Once the artery is located, an absorbable suture is used to ligate the arterial blood flow.
In case of prolapsed hemorrhoids, a pexy is performed in order to lift the tissue back to its anatomical position.
