In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

Background: Female endoparasitic ichneumonid wasps inject virus-like particles into their caterpillar hosts to suppress immunity. These particles are classified as ichnovirus virions and resemble ascovirus virions, which are also transmitted by parasitic wasps and attack caterpillars. Ascoviruses replicate DNA and produce virions. Polydnavirus DNA consists of wasp DNA replicated by the wasp from its genome, which also directs particle synthesis. Structural similarities between ascovirus and ichnovirus particles and the biology of their transmission suggest that ichnoviruses evolved from ascoviruses, although molecular evidence for this hypothesis is lacking. Here we show that a family of unique pox-D5 NTPase proteins in the Glypta fumiferanae ichnovirus are related to three Diadromus pulchellus ascovirus proteins encoded by ORFs 90, 91 and 93. A new alignment technique also shows that two proteins from a related ichnovirus are orthologs of other ascovirus virion proteins. Our results provide molecular evidence supporting the origin of ichnoviruses from ascoviruses by lateral transfer of ascoviral genes into ichneumonid wasp genomes, perhaps the first example of symbiogenesis between large DNA viruses and eukaryotic organisms. We also discuss the limits of this evidence through complementary studies, which revealed that passive lateral transfer of viral genes among polydnaviral, bacterial, and wasp genomes may have occurred repeatedly through an intimate coupling of both recombination and replication of viral genomes during evolution. The impact of passive lateral transfers on evolutionary relationships between polydnaviruses and viruses with large double-stranded genomes is considered in the context of the theory of symbiogenesis. Parasitic wasps belonging to the families Ichneumonidae and Braconidae are among the most successful higher eukaryotic organisms. These two large families contain more than 37,000 known species, and estimates of the total number of species are as high as 100,000 [1].
Molecular evidence for the evolution of ichnoviruses from ascoviruses by symbiogenesis

O. is a 37-year-old male with no significant past medical history who presented to the Emergency Department with a one week history of worsening dysphagia and odynophagia. He reported he was usually in good health until the current symptoms began. Scott said that he had been unable to swallow solid foods over the past week, largely due to increasing pain on swallowing, and was now unable to swallow liquids as well. Although he stated that his appetite was unchanged, he estimated a fivepound weight loss over the last week due to poor oral intake. He otherwise denied fever, respiratory or gastrointestinal symptoms, or any other complaints. He takes no medications at home except for rare acetaminophen. He is married, has a twoyear-old son, and works as an attorney. He denied use of tobacco, alcohol, or illicit drugs. Family history was noncontributory. On physical exam, he was afebrile and his vital signs were within normal limits. Cardiovascular, respiratory, abdominal, extremity, and neurologic exam were unremarkable. There was some mild oropharyngeal thrush, palpable bilateral inguinal lymphadenopathy, and a 1 cm painless ulceration on the penile shaft. Laboratory evaluation was unremarkable.

Background: On the 30th September 2009, the pandemic (H1N1) 2009 influenza vaccine was made available to adults and children aged 10 years and over, in Australia. Acceptance of a novel vaccine is influenced by perceptions of risk including risk of infection, risk of death or severe illness and risk of serious vaccine side-effects. We surveyed a sample of residents from Sydney, Australia to ascertain their risk perception, attitudes towards the pandemic and willingness to accept the pandemic (H1N1) 2009 influenza vaccine. We sampled residents using a cross-sectional intercept design during the WHO Phase 6. Members of the public were approached in shopping and pedestrian malls to undertake the survey during September and October 2009. The survey measured perceived risk, seriousness of disease, recent behavioural changes, likely acceptance of the pandemic (H1N1) 2009 vaccine and issues relating to uptake and perceived safety.
