According to some, Adonis was born from the tree into which Smyrna had transformed either when his father clove it with his sword, or when a boar opened it with his tusks. Roscher, Lex. 1.70.49, 1.71.15. Adonis died of a wound in his knee caused by a boar.
Here we focus on the extrinsic and intrinsic incubation periods of DENV infections. The extrinsic incubation period (EIP) is the viral incubation period between the time when a mosquito takes a viremic bloodmeal and the time when that mosquito becomes infectious. The intrinsic incubation period (IIP) is the time between a human being infected and the onset of symptoms due to the infection.
The coagulant activity of Factor VII, the major plasma component of the extrinsic pathway, is increased by Factor IXa of Factor XIIa of the contact system. These events take only about 15 seconds. The intrinsic pathway can be viewed as coagulation initiated by components entirely contained within the vasculature. This pathway results in the activation of Factor IX by Factor XIa, providing a pathway independent of Factor VII for blood coagulation.
