Novel influenza viruses of the H7N9 subtype have infected 33 and killed nine people in China as of 10 April 2013. Their haemagglutinin (HA) and neuraminidase genes probably originated from Eurasian avian influenza viruses; the remaining genes are closely related to avian H9N2 influenza viruses. Several characteristic amino acid changes in HA and the PB2 RNA polymerase subunit probably facilitate binding to human-type receptors and efficient replication in mammals, respectively, highlighting the pandemic potential of the novel viruses.
Humans are rarely infected with avian influenza viruses, with the exception of highly pathogenic avian influenza A(H5N1) viruses, which have caused 634 infections and 371 deaths as of 12 March 2013 . A few isolated cases of human infection with viruses of the H7N2, H7N3, and H7N5 subtypes have been reported, but none were fatal [2-11]. In 2003, in the Netherlands, 89 people were infected with an influenza virus of the H7N7 subtype that caused conjunctivitis and one fatality [5,7].
It s wonderful to climb the liquid mountains of the sky. Behind me and before me is God and I have no fears.

Don''''t panic when your instructor tells you that you need to write an analysis! All he or she wants is for you to take something apart to see HOW it works.
Caution! Make sure that you''''re NOT just summarizing the original article, story, novel, poem, etc. Go beyond simply telling us WHAT you are talking about: describe HOW and WHY its elements function.
a , Venn diagrams depict the relative contribution of SNPs, CNVs and CNAs to genome-wide, cis and trans tumour expression variation for significant expression associations (Šidák adjusted P -value ≤0.0001). b , Histograms illustrate the proportion of variance explained by the most significantly associated predictor for each predictor type, where several of the top associations are indicated.
a , Kaplan–Meier plot of disease-specific survival (truncated at 15 years) for the integrative subgroups in the discovery cohort. For each cluster, the number of samples at risk is indicated as well as the total number of deaths (in parentheses). b , 95% confidence intervals for the Cox proportional hazard ratios are illustrated for the discovery and validation cohort for selected values of key covariates, where each subgroup was compared against IntClust 3.
A novel is any relatively long piece of written narrative fiction , normally in prose , and typically published as a book.
The genre has also been described as possessing, "a continuous and comprehensive history of about two thousand years".  This view sees the novel's origins in Classical Greece and Rome , medieval , early modern romance , and the tradition of the novella. The latter, an Italian word used to describe short stories , supplied the present generic English term in the 18th century. Ian Watt , however, in The Rise of the Novel (1957) suggests that the novel first came into being in the early 18th century,
