Where risk assessment shows air-purifying respirators are appropriate use a full-face particle
respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering
controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use
respirators and components tested and approved under appropriate government standards such
as NIOSH (US) or CEN (EU).

  The metalloproteinase meprin β emerged as a current drug target for the treatment of a number of disorders, among those fibrosis, inflammatory bowel disease and Morbus Alzheimer. A major obstacle in the development of metalloprotease inhibitors is target selectivity to avoid side effects by blocking related enzymes with physiological functions.
