Blood samples were taken in early (≤48 hrs post-diagnosis, n = 54), latent (seven days post-diagnosis, n = 39) and convalescent (3-6 months post-diagnosis, n = 18) phases of disease.
LPAI-inoculated birds also have a longer latent period (1.21 days) than HPAI-inoculated birds (0.28 day).
Rabbits were considered latent at >28 days PI at which time no corneal or ocular lesions were detected by SLE.
To realize this purpose, male Wistar rats in the latent phase (3 days after pilocarpine administration) were examined.
It is possible to carry out MLD in the case of late or latent lymphoedema three days postsurgery if contraindications do not exist.
There are therefore four parameters estimated per isolator: the primary/secondary latent periods (in days) and the primary/secondary rates of viral shedding (VCN/mg dust).
Time series of microarray expression profiles of heads of flies treated with PTZ for 12 hrs (beginning phase), two days (latent phase) and seven days (behaviorally expressive phase) showed only down-, not up-, regulatiof of genes; expression of 23, 2439 and 265 genes were downregulated, in that order.
This allows further activation of these receptors through glutamate and Ca influx into postsynaptic cells [ 40] what we might observe as a secondary increase of the Ca level in CA3, DG, and H hippocampal areas in the latent phase (4 days after pilocarpine administration).
We do not explicitly characterise symptom onset in our model, but assume a one-day latent period (E) between inoculation and the onset of three days' constant infectious duration (I), exponentially distributed over the period, of which at least part of one day is likely to be presymptomatic.
This was characterised by an approximately 100-fold deficit of latent infection at day 14 post-inoculation and a subsequent increase in infectious centres by day 21 post-inoculation when compared with infections made with wild type viruses (Fig. 5).
