Paragraph: Background: The widespread nursing shortage is of concern in Mainland China and globally. Factors underpinning the increased mobility of the nursing workforce and their contribution to nurses' turnover thus merit attention. Understanding nurses' job satisfaction is important, as this is a key factor in nurses' turnover. Objective: The study aimed to explore nurses' views and experience regarding different components of their working lives in Mainland China. Methods: A cross-sectional survey design was selected and 512 nurses working in the medical and surgical departments in two teaching hospitals in Beijing completed questionnaires yielding a response rate of 81%. Results: More than half of nurses (53.7%; n ¼ 275) were satisfied or very satisfied with their jobs and 15% (n ¼ 77) felt moderate to extreme occupational stress. The majority of the sample reported a high level of organizational commitment (63.7%; n ¼ 326) and professional commitment (85.9%; n ¼ 440) and only 5.9% (n ¼ 30) and 10.0% (n ¼ 51), respectively reported role conflict and role ambiguity often or very often. Nurses with a diploma or associate degree reported greater professional commitment and a lower level of role conflict than those with a bachelor degree (po0.05), but there were no significant differences in job satisfaction, organizational commitment, occupational stress and role ambiguity by educational programme (p40.05). Conclusions: Hospital nurses' positive feelings regarding their working lives may be influenced by developments in the health care system and the nursing profession in Mainland China. Nurses' educational level is an influencing factor on nurses' views and experiences of their working lives with the findings suggesting the need to develop a clinical career ladder for nursing staff in Mainland China. r

Paragraph: Retroviruses are classified as exogenous and endogenous retroviruses according to the mode of transmission. Endogenous retroviruses (ERVs) are retroviruses which have been integrated into germ-line cells and inherited from parents to offspring. Most ERVs are inactivated by deletions and mutations; however, certain ERVs maintain their infectivity and infect the same host and new hosts as exogenous retroviruses. All domestic cats have infectious ERVs, termed RD-114 virus. Several canine and feline attenuated vaccines are manufactured using RD-114 virus-producing cell lines such as Crandell-Rees feline kidney cells; therefore, it is possible that infectious RD-114 virus contaminates live attenuated vaccines. Recently, Japanese and UK research groups found that several feline and canine vaccines were indeed contaminated with infectious RD-114 virus. This was the first incidence of contamination of 'infectious' ERVs in live attenuated vaccines. RD-114 virus replicates efficiently in canine cell lines and primary cells. Therefore, it is possible that RD-114 virus infects dogs following inoculation with contaminated vaccines and induces proliferative diseases and immune suppression, if it adapts to grow efficiently in dogs. In this review, we summarize the incidence of contamination of RD-114 virus in live attenuated vaccines and potential risks of infection with RD-114 virus in dogs. Retroviruses enter host cells via binding of the envelope proteins with the host receptor(s). After entering the cells, viral RNA is reverse-transcribed into DNA and then the DNA is integrated into the host genome to be a provirus. Viral RNA is transcribed from the provirus and the structural and enzymatic proteins of the virus are synthesized from the transcribed viral RNA. Retroviruses are classified as exogenous and endogenous retroviruses according to the mode of transmission [14] . Usually, exogenous retroviruses infect somatic cells but not germ-line cells, and they are transmitted horizontally by infection via viral particles. On the other hand, ERVs are retroviruses which have been integrated into germ-line cells. ERVs behave like normal genes and are inherited from parents to offspring as Mendelian's law. ERVs occupy about 10 % of mammalian genomes and are mostly inactivated by deletions and mutations [14, 15, 17, 27] . However, a limited number of ERVs maintain their infectivity and infect new hosts as exogenous retroviruses [6] . Exogenous retroviruses are classified into seven genera, i.e., alpharetrovirus, betaretrovirus, gammaretrovirus, deltaretrovirus, epsilonretrovirus, spumaretrovirus and Electronic supplementary material The online version of this article (

Paragraph: The conversion of ribavirin to the monophosphate by adenosine kinase is the rate-limiting step in activation of this broad spectrum antiviral drug. Variation of the 3-substituents in a series of bioisosteric and homologated 1-b-D D-ribofuranosyl-1,2,4-triazoles has marked effects on activity with the human adenosine kinase, and analysis of computational descriptors and binding models offers insight for the design of novel substrates.
