[Conclusion] HBeAg(+), Pre-S1Ag(+) or HBV-DNA(+) in pregnant women is one of the high risk factors of fetal intrauterine infection. Intrauterine infectious rate increased significantly when HBV DNA load was increased in blood of pregnant women.
Results: The total of HBV infection and positive of HBsAg in pregnant women were 8.63%(264/3060) and 8.19%(251/3060). Twelve modes had been confirmed and it was more common in the mode of positive of HBsAg, anti-HBe, anti-HBc which was possessed of 35.98%(95/264).
The relationship between viral load and various cervical diseases were analysed by unconditional multinomial logistic regression. RESULTS: The positive rates of HPV infection were 21.29% and 82.35%, 80.00%, 90.16%, 86.67% in control group and women with CIN Ⅰ, CIN Ⅱ, CIN Ⅲ, invasive cervical carcinoma, respectively.
Two typical delay regimes, i.e., uniform and degree-dependent delays are incorporated into the SIS epidemic model to investigate the epidemic infection processes in the local-world network model.
The results indicate that the infection delay will promote the epidemic outbreaks, increase the prevalence and reduce the critical threshold of epidemic spreading.
AM infection was severely restrained by 12% soil water content.
Relative water content (RWC), chlorophyll, soluble sugar and starch content of EI and EF populations under normal and drought stress conditions were compared to investigate the effect of endophyte infection on the host plant.
Both genes were determined to be nonessential in viral replication and infection.
