Abstract

Abstract This report describes the genetic characterization of 297 wild-type measles viruses that were isolated in 24 provinces of China between 1995 and 2003. Phylogenetic analysis of the N gene sequences showed that all of the isolates belonged to genotype H1 except 3 isolates, which were genotype A. The nucleotide sequence and predicted amino acid homologies of the 294-genotype H1 strains were 94.7%–100% and 93.3%–100%, respectively. The genotype H1 isolates were divided into 2 clusters, which differed by approximately 2.9% at the nucleotide level. Viruses from both clusters were distributed throughout China with no apparent geographic restriction and multiple co-circulating lineages were present in many provinces. Even though other measles genotypes have been detected in countries that border China, this report shows that genotype H1 is widely distributed throughout the country and that China has a single, endemic genotype. This important baseline data will help to monitor the progress of measles control in China.

Abstract

In this paper, a distributed chunk-based optimization algorithm is proposed for the resource allocation in broadband ultra-dense small cell networks. Based on the proposed algorithm, the power and subcarrier allocation problems are jointly optimized. In order to make the resource allocation suitable for large scale networks, the optimization problem is decomposed first based on an effective decomposition algorithm named optimal condition decomposition (OCD) algorithm. Furthermore, aiming at reducing implementation complexity, the subcarriers are divided into chunks and are allocated chunk by chunk. The simulation results show that the proposed algorithm achieves more superior performance than uniform power allocation scheme and Lagrange relaxation method, and then the proposed algorithm can strike a balance between the complexity and performance of the multi-carrier Ultra-Dense Networks.

Abstract

Objective: To evaluate the effectiveness of small interfering RNA (siRNA) on inhibiting severe acute respiratory syndrome (SARS)-associated coronavirus replication, and to lay bases for the future clinical application of siRNA for the treatment of viral infectious diseases., Methods: Vero-E6 cells was transfected with siRNA before SARS virus infection, and the effectiveness of siRNA interference was evaluated by observing the cytopathic effect (CPE) on Vero-E6 cells., Results: Five pairs of siRNA showed ability to reduce CPE dose dependently, and two of them had the best effect., Conclusion: siRNA may be effective in inhibiting SARS-associated coronavirus replication.
