将preproBNP从细胞分泌到血液中的过程中,细胞会去除这一段讯息胜肽,而成为含有108个胺基酸的proBNP。随后proBNP会被转化酶(convertase)从第102和103个胺基酸之间裂解,产生出二个产物:一个产物是长76个胺基酸,不具生物活性的NT-proBNP,另一个产物为长32个胺基酸,具备生物活性的BNP。上述二者会在同一时间释放到血液...

Since then, nearly everyone has listed it as a primary Alexandrian witness: Von Soden listed it as a member of the H type; the Alands list it as Category I (which, in practice, means purely Alexandrian); Wisse lists it as Group B in Luke; Richards classifies it as A2 (i.e. a ...
In practice, it is impossible to predict with absolute certainty how any individual component will perform. Therefore, we must utilize probability theory. It is also necessary to clearly define the level of stress involved (e.g., operating voltage, ripple current, temperature and time). Finally,...
