The digestive system is an example of an organ system in which humans and other mammals exchange substances with the environment. The table shows its main tissues and organs, and their functions:
Monocryl is a synthetic, absorbable suture, manufactured and trademarked by Ethicon. It is composed of poliglecaprone 25, which is a copolymer of glycolide and epsilon-caprolactone.It comes both dyed (violet) and undyed (clear), and is a monofilament suture. It is generally used for soft-tissue approximation and ligation.t 1 week, its in vivo tensile strength is at 50-60% undyed (60-70% dyed), at 2 weeks its 20-30% undyed (30-40% dyed), and is essentially completely hydrolyzed by 91â119 days. When removed from the package, it has a high degree of memory, or coil.
Monoclonal antibodies can block these receptors and prevent the growth signal from getting through. Cetuximab (Erbitux), a monoclonal antibody approved to treat colon cancer and head and neck cancers, attaches to receptors on cancer cells that accept a certain growth signal (epidermal growth factor).he cancer cells then ingest the antibody, which releases a few molecules of chemotherapy. The chemotherapy only damages the cancer cells, leaving the surrounding healthy cells undamaged. A number of monoclonal antibody drugs are available to treat various types of cancer.
