Sequence Analysis of the Fusion Protein Gene of Human Respiratory Syncytial Virus Circulating in China from 2003 to 2014.

The human respiratory syncytial virus (HRSV) fusion (F) protein is important for HRSV infection, but few studies have examined the genetic diversity of the F gene from Chinese samples. In this study, a total of 330 HRSV F sequences collected from different regions of China between 2003 and 2014 were analyzed to understand their genetic characteristics. In addition, these sequences were compared with 1150 HRSV F sequences in Genbank from 18 other countries.

Mumps incidence in mainland China remains at a high level. Genotype F has been the predominant genotype of mumps virus (MuV) in the last 20 years in mainland China. To better understand the genetic characteristics of MuV in China, the sequences of the Small Hydrophobic (SH), Hemagglutinin-Neuraminidase (HN) and Fusion (F) genes of MuVs of genotype F collected during 2001-2015 were determined.

Characterisation of a rare, reassortant human G10P[14] rotavirus strain detected in Honduras.

Background: Although first detected in animals, the rare rotavirus strain G10P[14] has been sporadically detected in humans in Slovenia, Thailand, United Kingdom and Australia among other countries. Earlier studies suggest that the strains found in humans resulted from interspecies transmission and reassortment between human and bovine rotavirus strains.

Objectives: In this study, a G10P[14] rotavirus genotype detected in a human stool sample in Honduras during the 2010-2011 rotavirus season, from an unvaccinated 30-month old boy who reported at the hospital with severe diarrhea and vomiting, was characterised to determine the possible evolutionary origin of the rare strain.

Emergence of BA9 genotype of human respiratory syncytial virus subgroup B in China from 2006 to 2014.

A study was conducted to investigate the circulation of HRSV subgroup B (HRSVB) in China in recent years. HRSVB sequences from 365 samples collected in 1991, 2004 and 2008-2014 in China, together with 332 Chinese HRSVB sequences obtained from GenBank were analyzed to determine the geographic and yearly distribution of HRSVB. Phylogenetic analysis revealed these HRSVB sequences clustered into 4 genotypes with different frequencies: BA (83%), CB1 (11%), SAB (3.

TALENs-mediated homozygous CCR5Δ32 mutations endow CD4+ U87 cells with resistance against HIV‑1 infection.

Since evidence suggests that transplantation of bone marrow stem cells with the C‑C chemokine receptor type 5 (CCR5)Δ32/Δ32 genotype may cure patients infected with human immunodeficiency virus (HIV)‑1, the present study aimed to reproduce the CCR5Δ32 mutation in cluster of differentiation (CD)4+ U87 cells using genome engineering methods. A modified transcription activator‑like effector nucleases (TALENs) technique, combined with homologous recombination for site‑specific, size‑controlled and homozygous DNA deletions, was used to reproduce the homozygous CCR5Δ32 mutation in CD4+ U87 cells. The results indicated that the frequency of the TALENs‑targeted mutation reached 50.

Characteristics of influenza H13N8 subtype virus firstly isolated from Qinghai Lake Region, China.

Background: Since the highly pathogenic H5N1 influenza caused thousands of deaths of wild bird in this area in 2005, Qinghai Lake in China has become a hot spot for study of the influence of avian influenza to migratory wild birds. However, the ecology and evolution of low pathogenic avian influenza virus in this region are limited. This project-based avian influenza surveillance in Qinghai lake region was initiated in year 2012.

Five-Year Survival is Not a Useful Measure for Cancer Control in the Population: an Analysis Based on UK Data.

Background: Five-year survival is an important metric for progress in cancer control broadly used both in the cancer literature and by the public. In order to assess its validity and relation to other common metrics, we analyzed the relationship between 5-year survival, incidence and mortality using publicly available cancer registry data from England and Wales. Methods: Five-year survival, incidence and mortality data were obtained from the online database of a registered charity, Cancer Research UK.
