The Guardia Pro Protective Embryo Transfer Catheteris uniquely engineered to protect and guide embryos through cervical mucus and blood and to eliminate the need for cervical flushing or aspiration prior to transfer. The Guardia Pro’s outer sheath protects the embryo through entry and then opens in petals to further advance the inner transfer catheter allowing placement of the embryo in the uterine cavity.
Researchers at the University of Michigan have devised a microscale tool to help them understand the mechanical behavior of biofilms, slimy colonies of bacteria involved in most human infectious diseases. Most bacteria in nature take the form of biofilms. Bacteria are single-celled organisms, but they rarely live alone, said John Younger, associate chair for research in the Department of Emergency Medicine at the U-M Health System.
