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)
The complete nucleotide sequences of two isolates of apple chlorotic leaf spot virus (Z1 and Z3) collected from peach in Henan Province, China, were determined. The genomes of both Z1 and Z3 were found to contain three open reading frames (ORFs). Sequence analysis showed that genomic sequences of Z1 and Z3 isolates shared 67.4%-82.9% and 67.2%-82.6%(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)
Australian grapevine viroid (AGVd) is found in only three countries in the world. Here, the genetic diversity and phylogenetic relationships of AGVd isolates from three different grape varieties (Thomson Seedless, Jingchuan and Zaoyu) in China were studied. A hundred of independent cDNA clones from each of the three isolates, in total of 300, were(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)
Grapevine yellow speckle viroid-2 (GYSVd-2) is a viroid found only in grapevines in China and Australia. Here, we report the molecular characterization of GYSVd-2 isolated from three grapevine varieties in China. A total of 90 cDNA clones were sequenced including 30 cDNA clones obtained from each of the Black Olympia, Zaoyu, and Thomson Seedless isolates.(More)
The aim of the present study was to examine cerebral vasoconstriction in patients with chronic high altitude disease [cerebrovascular reactivity (CVR)], and to evaluate differences in alterations of brain vascular contractile reactivity of chronic mountain sickness (CMS) patients and healthy controls. Alterations of endothelin (ET) and its receptor, as well(More)
Fetuin-A was considered to be involved in pathogenesis of type 2 diabetes. On the other hand, higher vascular endothelial growth factor (VEGF) expression is associated with diabetes and its vascular complications, but the mechanisms leading to higher VEGF levels are still not clear. To the best of our knowledge, there are no data to show the associations(More)
