Methods Calcein-AM stained H9/HIV-1 ⅢB cells were treated with difierent concentrations of PF in the first,second and third trimesters respectively,which was then mixed with MT2 cells and put under fluorescent microscopy for detection of HIV-1-mediated syncytium formation.MT2 cells were treated with cell-free HIV-1 Ⅲ B,and then washed and cultured with different concentrations of PF in the first,second and third trimesters respectively.Furthcrly,the protecting effect of PFs against HIV-1-infected cells Was determined with MTT,viral replication Was evaluated by measurement of the levels of p24 antigen in culture supernatants with ELISA and the inhibition rate Was calculated.

In order to improve the existing generic service oriented intrusion tolerant system in aspect of architecture and function, this paper presents an improved adaptive intrusion tolerant system with improved architecture, functional modules and key techniques. From an overall consideration of the system, mixed with firewall, intrusion detection and other traditional technologies, IAITS combines redundancy, diversity and various fault tolerant techniques, thus enhancing reliability through active replication and secure multicast, reaching tradeoff between system complexity and intrusion tolerance ability by redundant design only in most vulnerable components, and supporting data protection on the basis of architecture with only a little extra cost in software and hardware by making use of topological coherence between application servers group and key share servers group.

Lara made up imaginary records and pasts for a pair of nuclear researchers named Bert and Jennifer Kelly, neither of whom had mutations of their own, and explained to Alatan that her mutation was the result of a sperm cell failing to undergo meiotic division, which necessitated an in-depth discussion of chromosomes, DNA replication, and Alatan's own syndrome of triploidy.

The results from an example showed that the unbiased estimate of error variance could be obtained so that polygenic variance and polygenic heritability could not be underestimated. Moreover, the AIC values by using the average of two replications were less than that by using the observations of a replication.
