Dark-grown transgenic Arabidopsis seedlings expressing the C-terminal domains (CCT) of the cryptochrome (CRY) blue light photoreceptors exhibit features that are normally associated only with light-grown seedlings, indicating that the signaling mechanism of Arabidopsis CRY is mediated through CCT. The phenotypic properties mediated by CCT are remarkably(More)
Most organisms, from cyanobacteria to mammals, use circadian clocks to coordinate their activities with the natural 24-h light/dark cycle. The clock proteins of Drosophila and mammals exhibit striking homology but do not show similarity with clock proteins found so far from either cyanobacteria or Neurospora. Each of these organisms uses a transcriptionally(More)
OBJECTIVE Methadone maintenance treatment (MMT) was introduced to China in 2004 to reduce the harm of injecting drug users (IDUs). However, little is known about continued drug use, especially methamphetamine (MAMP), among MMT patients. METHODS A survey was conducted among patients attending five major MMT clinics in Dehong Prefecture in 2014 to(More)
We demonstrate a method to control the distribution of magnetic Co ions in Co-doped SnO2 nanorods by the surfactant. The nanorods with nanoflower morphology have been synthesized by surfactant-assisted hydrothermal method. The X-ray absorption fine structure spectra at Co K-edge reveal that Co ions substitute for Sn site in SnO2 lattice. The X-ray(More)
OBJECTIVE To study the incidence rate and risk factors of HIV infection among sero-negative spouses of people living with HIV/AIDS (HIV/AIDS) in Dehong prefecture, Yunnan province. METHODS A prospective cohort study was conducted from February 2009 to December 2014 in Dehong prefecture, Yunnan province. Questionnaire survey and HIV related tests were(More)
OBJECTIVE An approach for analysis of hepatitis C virus (HCV) quasispecies using Hiseq high-throughput sequencing (hereinafter referred to as Hiseq sequencing) technique was developed and then applied to investigate a possible case of HCV needle sharing transmission. METHODS One case of HCV antibody seroconversion (P1) was found in a methadone clinic on(More)
Objective: To analyze the distribution of hepatitis C virus (HCV) genotypes among Chinese and Burmese drug users in Dehong Prefecture, Yunnan Province. Methods: Plasma specimens and relevant epidemiological data were collected from 7 545 drug users attending rehabilitation centers and methadone clinics in Dehong Prefecture from January to September in 2015,(More)
OBJECTIVE To understand the characteristics and retention situation of clients in extension clinic of methadone maintenance therapy. METHODS From December 20, 2010 to March 10, 2011, the system sampling method was used to get the cases. A total of 462 heroin addicts from 22 methadone maintenance therapy clinics and extension clinics located in Mangshi,(More)
