BACKGROUND During the spring of 2013, a novel avian-origin influenza A (H7N9) virus emerged and spread among humans in China. Data were lacking on the clinical characteristics of the infections caused by this virus. METHODS Using medical charts, we collected data on 111 patients with laboratory-confirmed avian-origin influenza A (H7N9) infection through(More)
BACKGROUND An epidemic of severe acute respiratory syndrome (SARS) has been associated with an outbreak of atypical pneumonia originating in Guangdong Province, People's Republic of China. We aimed to identify the causative agent in the Guangdong outbreak and describe the emergence and spread of the disease within the province. METHODS We analysed(More)

The high frequency of epidermal growth factor receptor (EGFR) mutations in tyrosine kinase inhibitor-responsive non-small-cell lung cancer (NSCLC) cases is now well established, highlighting the predictive value of activating EGFR mutations in guiding the clinical use of EGFR-targeted therapies. However, specimen source and methods for EGFR mutation(More)
Mutations in the DJ-1 gene cause early-onset autosomal recessive Parkinson's disease (PD), although the role of DJ-1 in the degeneration of dopaminergic neurons is unresolved. Here we show that the major interacting-proteins with DJ-1 in dopaminergic neuronal cells are the nuclear proteins p54nrb and pyrimidine tract-binding protein-associated splicing(More)
BACKGROUND There is increasing evidence for a possible association between chronic obstructive pulmonary disease (COPD) and the use of biomass fuels for cooking and heating in developing countries. Data on the prevalence of COPD and objective measurements of indoor pollution from biomass fuel have not been widely available from China. A study was undertaken(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterised by airflow limitation, and has many components including mucus hypersecretion, oxidative stress, and airway inflammation. We aimed to assess whether carbocisteine, a mucolytic agent with anti-inflammatory and antioxidation activities, could reduce the yearly exacerbation rate in(More)
In this randomised double-blind study, patients >or=40 years old with COPD, a smoking history of >or=10 pack-years, a pre-bronchodilator FEV(1) of <or=60% predicted and an FEV(1)/FVC of <or=70% received tiotropium 5 microg or placebo via Respimat inhaler once daily for 48 weeks. Other medications were permitted except inhaled anticholinergics. Co-primary(More)
Distributions of popularity of many online markets have long tails. However, the profitability of the long tail remains in dispute among researchers. With an analysis of an extensive dataset of Google Play transactions, this work first examine the long tail of the mobile application market. Our results suggest that Google Play is more of a "Superstar"(More)
