Bordetella pertussis stain (Gram-negative, coccobacilli, diplococci arrangement), growth on Bordet-Gengou agar or BCYE plate with added cephalosporin to select for the organism, which shows mercury drop-like colonies. "B. pertussis" can also be detected by PCR, which is more sensitive than culture. The primers used for PCR usually target the transposable elements IS481 and IS1001. Several diagnostic tests are available, especially ELISA kits. These are designed to detect FHA and/or PT antibodies of IgG, IgA, or IgM. Some kits use a combination of antigens which lead to a higher sensitivity, but might also make the interpretation of the results harder, since one cannot
Coronary artery disease of adult stem cell populations. Research is still going on – with first promising results particularly for FGF-1 and utilization of endothelial progenitor cells. Myeloperoxidase has been proposed as a biomarker. Dietary changes can decrease coronary artery disease. For example, data supports benefit from a plant-based diet and aggressive lipid lowering to improve heart disease. Coronary artery disease Coronary artery disease (CAD), also known as ischemic heart disease (IHD), is the most common of the cardiovascular diseases. Types include stable angina, unstable angina, myocardial infarction, and sudden cardiac death. A common symptom is chest pain or discomfort which may travel
