The complete nucleotide sequences of three sugarcane streak mosaic virus (SCSMV) isolates found in sugarcane plants imported from Japan (JP1, JP2) and Indonesia (ID) into China were determined. Sequence analysis showed that, based on the whole genome sequence and the nucleotide sequences encoding the ten mature proteins, the three SCSMV isolates shared(More)
With the smoking epidemic in China, the role that health care providers (HCPs) could play in tobacco control will be critical. As a preliminary step, this study identified smoking behavior, knowledge, attitudes, and practice (KAP) regarding smoking and smoking control among HCPs in Changsha city, China. The study design was cross-sectional. The instruments(More)
A simple and fast sap-direct RT-PCR (reverse transcription-polymerase chain reaction) for the rapid detection of 3 viroids of the genus Coleviroid is presented. The templates for cDNA synthesis were obtained directly from the sap of coleus using a pipettor, a common tool in molecular biology laboratories, and 3 coleus blumei viroids (CbVds) were detected(More)
Four viroid species infecting Coleus blumei, named Coleus blumei viroid 1-4 (CbVd-1-CbVd-4), and two tentative new viroid species, named CbVd-5 and CbVd-6, have been characterized, for two of which (CbVd-5 and CbVd-6, first reported in 2009), there is no established bioassay. Here, infectious clones were used as inoculums sources and the biological(More)
The complete nucleotide sequence of Cymbidium mosaic virus (CymMV) isolated from vanilla in Hainan province, China was determined for the first time. It comprised 6,224 nucleotides; sequence analysis suggested that the isolate we obtained was a member of the genus Potexvirus, and its sequence shared 86.67-96.61% identities with previously reported(More)
The ornithine decarboxylase antizyme 2 (OAZ2) gene is a member of the antizyme gene family. Antizymes play pivotal roles in various cellular pathways, including polyamine anabolism and apoptosis. The molecular structure and expression profile of the OAZ2 in goose ovarian follicles have not been reported. In this study, the OAZ2 cDNA sequence of the Sichuan(More)
Antizyme inhibitor 1 (Azin1) plays critical roles in various cellular pathways, including ornithine decarboxylase regulation, polyamine anabolism and uptake and cell proliferation. However, the molecular characteristics of the AZIN1 gene and its expression profile in goose tissues and ovarian follicles have not been reported. In this study, the AZIN1 cDNA(More)
We propose a streaming video system, which can be used in various system environments. This system has three features for providing real-time video delivery services in the Internet. The first is to use QoS (quality of service) control rules adapting to the system environments. The second is to improve estimation accuracy of the network conditions while a(More)
Internet Telephony grants users the power of developing their own telephony services, and the Call Processing Language (CPL) has been designed to to fulfil this target. However, this objective confronts a major obstacle known as the feature interaction problem, which describes the situation that one feature or service is violated by another in overall(More)
This paper presents personalized services (policies) specified in extended call processing language (CPL) and their mobility. With three-layered service architecture, both personalized services and their mobility for call-processing and presence are described in the session initiation protocol (SIP) environment. To provide the security for service mobility(More)
