Viral diarrhea is a great threat to children’s health in developing countries. We conducted a prospective surveillance study of acute diarrhea of young children at Tianjin Children’s Hospital from April 2008 to April 2009. Viral infections were detected in 356 of the total 766 collected stool specimens (46.48%). Rotavirus infections were the most common(More)
The genetic evolution of HIV-1 in the central nervous system (CNS) is different from that in peripheral tissues. We analyzed 121 clonal sequences of the V3–V5 regions of the env gene generated from paired cerebrospinal fluid (CSF) and plasma samples from nine chronically infected patients (four with HIV-associated neurocognitive disorder (HAND) and five(More)
UNLABELLED Correlated mutations constitute a fundamental idea in evolutionary biology, and understanding correlated mutations will, in turn, facilitate an understanding of the genetic mechanisms governing evolution. CorMut is an R package designed to compute correlated mutations in the unit of codon or amino acid mutation. Three classical methods were(More)
BACKGROUND The polymorphisms involved in drug resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) in HIV-1 CRF_BC, the most prevalent HIV-1 strain in China, have been poorly characterized. RESULTS To reveal the drug resistance mutations, we compared the gene sequences of pol region of HIV-1 CRF_BC from 631 treatment-naïve and 363(More)
ASPP2 can bind to p53 and enhance the apoptotic capabilities of p53 by guiding it to the promoters of pro-apoptotic genes. Here, ASPP2 overexpression for 24 hours transiently induced apoptosis in hepatoma cells by enhancing the transactivation of p53 on pro-apoptotic gene promoters. However, long-term ASPP2 overexpression (more than 48 hours) failed to(More)
Description CorMut provides functions for computing kaks for individual sites or specific amino acids and detecting correlated mutations among them. Two methods are provided for detecting correlated mutations ,including conditional selection pressure and mutual information. The computation consists of two steps: First, the positive selection sites are(More)
The mechanisms behind HIV-1-associated neurocognitive disorders are still unclear. Apoptosis-stimulating protein 2 of p53 (ASPP2) is a damage-inducible p53-binding protein that stimulates p53-mediated apoptosis and transactivates proapoptotic and cell cycle regulatory genes. It has been reported that ASPP2 has a specific regulatory function in the death of(More)
Radiofrequency ablation (RFA) represents a valuable choice in hepatocellular carcinoma (HCC); however, local recurrence of HCC is common after RFA. Here, 20 primary HCC patients treated by RFA were enrolled. Before (termed 0d) and after RFA treatment for 1 and 7 days (termed 1d and 7d, respectively), plasma and noncancerous tissue were collected. ELISA(More)
HIV-1 subtype B’ isolates have been predominantly circulating in China. Their intra- and inter-subtype neutralization sensitivity to autologous and heterologous plasmas has not been well studied. Twelve HIV-1 B’ clinical isolates obtained from patients were tested for their intra- and inter-subtype neutralization sensitivity to the neutralization antibodies(More)
