Example Input: The circRNA is a newly defined noncoding RNA and characterized by its unique splicing reactions to form circles. However, the function of circRNAs during viral infection remains largely unknown. In this study, the circRNA expression profile during porcine endemic diarrhea virus (PEDV) infection in IPEC-J2 cell line was investigated using the next-generation sequencing technology. A total of 26670 circRNA candidates were identified. The functional annotation analysis revealed that the parent genes of differentially expressed circRNAs might be associated with host response to PEDV infection. Further analysis verified the existence of eight selected circRNAs and confirmed that PEDV infection alerted the expression patterns of circRNAs and their linear parent genes in IPEC-J2 cell line. The circRNA-miRNA interaction network was also constructed to elucidate their potential targets. Our results provided not only the first large-scale profile analysis of circRNAs associated with PEDV infection but also a novel direction to elucidate host-PEDV interactions.
Example Output: Profile analysis of circRNAs induced by porcine endemic diarrhea virus infection in porcine intestinal epithelial cells

Example Input: Fowl adenovirus serotype 4 (FAdV-4) is the causative agent of hydropericardium syndrome. To clarify the effects of FAdV-4 on immune organs in birds, we conducted a detailed examination of dynamic morphology and damage mechanisms in chickens randomly divided into 4 groups (FAdV-4, vaccination, FAdV-4 plus vaccination, and control). FAdV-4 caused the depletion of lymphocytes and subsequent growth impairment in the thymus and bursa. Chickens infected with FAdV-4 and subjected to vaccination experienced greater inhibition of antibody responses to inactivated vaccines against Newcastle disease and avian influenza virus subtype H9 than uninfected and vaccinated chickens. The mechanisms underlying adenovirus-mediated lymphoid organ damage were further investigated via transferase-mediated dUTP nickend labeling and apoptotic genes transcription analyses. Notably, lymphocytes apoptosis in lymphoid organs and expression of specific gene transcripts was significantly upregulated after infection (P < 0.05). Furthermore, increased expression of interleukin (IL)-6, IL-8, and tumor necrosis factor (TNF)-α mRNA was observed (P < 0.05), compared to the control group. Our collective findings suggested that FAdV-4 caused structural and functional damage of immune organs via apoptosis along with induction of a severe inflammatory response.
Example Output: Immunosuppressive potential of fowl adenovirus serotype 4

Example Input: Efforts to combat HIV, tuberculosis and malaria in sub-Saharan Africa in the past decade have underscored the inadequacy of laboratory systems in most African countries, as they were not equipped to perform vital testing for HIV care and prevention programmes. Laboratory testing is required for the diagnosis and management of these diseases and many other communicable and non-communicable diseases endemic to the African region. For many years, there had been steady neglect of national health laboratories in Africa, leading to a lack of trust in laboratory results and empiric treatment of patients. Early improvement efforts employed a vertical approach, creating national HIV-and AIDS-specific laboratories. This approach has proved inadequate, as it created competition for resources and did not improve the entire laboratory system in the countries. 1 It became clear that all laboratories in a country should be part of a fully-integrated laboratory network that can address both individual patient care needs and public health needs from the peripheral levels to the national level.
