"Title: Gain-of-Function Research: Ethical Analysis\nPassage: were published in 2012. Advocates of these studies/publications argued that they would improve surveillance of H5N1 in nature and facilitate development of vaccines that might be needed to protect against pandemic strains of the virus. Critics questioned the validity of claims about such benefits and argued that the studies might facilitate creation of biological weapons agents that could kill millions, or possibly even billions, of people.",
"Title: Why language matters: insights and challenges in applying a social determination of health approach in a North-South collaborative research program\nPassage: serve as outcome to measure quantitatively. We therefore set out to build the infrastructural capacity, while promoting the use of the material, leaving rigorous evaluation to a future date. Traditional epidemiology would consider this study a failure; however, the research process itself brought together communities, non-governmental organizations, national government and international agencies, serving to raise the level of awareness and conferring some empowerment to serve as a basis for future challenges to detrimental social processes. Table 3 assessed this collaborative research project with respect to the 4 S framework.",
"Title: Globalization and Health: developing the journal to advance the field\nPassage: review of all the articles that have been published to date. The purpose of this review was to identify strengths, trends and current gaps in research; highlight opportunities for strengthening existing research; and to propose upcoming areas of research, projected to be of increasing importance over the next ten years.",
"Title: Gain-of-Function Research: Ethical Analysis\nPassage: Some argued that publishing studies like these in full detail provided ''recipes'' for especially dangerous potential biological weapons agents to would-be bioterrorists. Many who acknowledged such potential dangers, on the other hand, argued that benefits of publication outweighed risks involved."

1169 | What does the MERS LRT disease involve? | [
"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: but close and lengthy exposure appears to be a requirement. The KSA is the focal point of MERS, with the majority of human cases. In humans, MERS is mostly known as a lower respiratory tract disease involving fever, cough, breathing difficulties and pneumonia that may progress to acute respiratory distress syndrome, multiorgan failure and death in 20 % to 40 % of those infected. However, MERS-CoV has also been detected in mild and influenza-like illnesses and in those with no signs or symptoms. Older males most obviously suffer severe disease and MERS patients often have comorbidities. Compared to severe acute",
"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: more selectively, interpreted as indicating their importation along with foreign pilgrims. Over time, increased influenza vaccination has been credited for a fall in the prevalence of influenza like illnesses among Hajj pilgrims. A LRT sample is often not collected for these studies , so false negative findings are a possibility although little is known about the initial site of MERS-CoV infection and replication; it may have been assumed it was the LRT because disease was first noticed there but the URT may be the site of the earliest replication.",

The KSA has been the source of 79 % of human cases. Severe MERS is notable for its impact among older men with comorbid diseases including diabetes mellitus, cirrhosis and various lung, renal and cardiac conditions . Interestingly in June 2015, an outbreak in South Korea followed a similar distribution . Among laboratory confirmed cases, fever, cough and upper respiratory tract signs and symptoms usually occur first, followed within a week by progressive LRT distress and lymphopaenia . Patients often present to a hospital with pneumonia,",
"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: Clinically suspected MERS cases may return negative results by RT-rtPCR. Data have shown one or more negative URT samples may be contradicted by further URT sampling or the use of LRT samples, which is preferred . Higher viral loads occur in the LRT compared to the URT. This fits with the observation that the majority of disease symptoms are reported to manifest as systemic and LRT disease .

The key limitations of serological testing is the need to collect paired serum samples from cases under investigation for confirmation to eliminate potential cross-reactivity from non-specific antibodies from past exposure and/or infection by other coronaviruses.

The fast and accurate diagnosis of a specific viral infection enables prompt and accurate public health surveillance, prevention and control measures. Local transmission and clusters can be prevented or delayed by isolation of laboratory-confirmed cases and their close contacts quarantined and monitored at home. Rapid diagnostic also facilitates other specific public health interventions such as closure of high-risk facilities and areas associated with the confirmed cases for prompt infection control and environmental decontamination ."

The best-known examples include severe acute respiratory syndrome CoV which emerged in China in 2002-2003 to cause a large-scale epidemic with about 8000",

"Title: Molecular and serological investigation of 2019-nCoV infected patients: implication of multiple shedding routes\nPassage: Text: Coronaviruses belong to the subfamily Orthocoronavirinae in the family Coronaviridae and the order Nidovirales. A human coronavirus caused the severe acute respiratory syndrome coronavirus outbreak in 2003. Most recently, an SARS-related CoV was implicated as the etiological agent responsible for the outbreak in Wuhan, central China. This outbreak is estimated to have started on 12th December 2019 and 17,332 laboratory confirmed cases with 361 deaths as of 3rd February 2020 in China . The virus has spread to 23 other countries by travellers from Wuhan . Typical symptoms are fever, malaise, shortness of breath and in severe cases, pneumonia",

Viral load was significantly reduced after completion of treatment.",
"Title: Overview of the 3rd isirv-Antiviral Group Conference – advances in clinical management\nPassage: Human rhinoviruses usually cause mild acute respiratory infections, but on occasions can also cause more severe respiratory infections, including exacerbations of asthma and COPD. Of 115 Japanese children with asthma, a respiratory virus was detected in 86%, of which HRV or RSV were most common. 79 Ex vivo bronchial epithelial cells from people with asthma are more susceptible to HRV infection, due to deficient induction of IFN-b and IFN-lambda. In a study of 147 asthmatics on inhaled corticosteroid therapy, with a history of virusassociated exacerbations, patients were randomised to 14-day treatment with inhaled IFN-b or placebo within 24 hours of"

"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: SARS-CoV that includes the split orf8b , civet SARS-CoV , two bat SARS-related-CoV containing full-length orf8 , 2019-nCoV, the other two closest bat SARS-related-CoV to 2019-nCoV SL-CoV ZXC21 and ZC45), and bat SARS-related-CoV HKU3-1 ). As expected, orf8 derived from 2019-nCoV belongs to the group that includes the closest genome sequences of bat SARS-related-CoV ZXC21 and ZC45. Interestingly, the new 2019-nCoV orf8 is distant from the conserved orf8 or Figure 5 ) which was shown to trigger intracellular stress pathways and activates NLRP3 inflammasomes , but this is absent in this novel orf8 of 2019-nCoV. Based on a secondary structure",
"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: Orf8 orf8 is an accessory protein found in the Betacoronavirus lineage B coronaviruses. Human SARS-CoVs isolated from early-phase patients, all civet SARS-CoVs, and other bat SARS-related CoVs contain fulllength orf8 . However, a 29-nucleotide deletion,",
"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: Bat which causes the split of full length of orf8 into putative orf8a and orf8b, has been found in all SARS-CoV isolated from mid-and late-phase human patients . In addition, we have previously identified two bat SARS-related-CoV and proposed that the original SARS-CoV full-length orf8 is acquired from these two bat SARS-related-CoV . Since the SARS-CoV is the closest human pathogenic virus to the 2019-nCoV, we performed phylogenetic analysis and multiple alignments to investigate the orf8 amino acid sequences.

"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: The single-stranded RNA genome of the 2019-nCoV was 29891 nucleotides in size, encoding 9860 amino acids. The G + C content was 38%. Similar to other . There are no remarkable differences between the orfs and nsps of 2019-nCoV with those of SARS-CoV . The major distinction between SARSr-CoV and SARS-CoV is in orf3b, Spike and orf8 but especially variable in Spike S1 and orf8 which were previously shown to be recombination hot spots."

For an outbreak caused by such pathogen, the only available data are about symptomatic infections or so at least at the early stage of the outbreak. Theoretically we can argue that if the proportion of symptomatic infections remains unchanged over the outbreak and there is no difference in transmissibility between symptomatic and asymptomatic infections, the estimate of R 0 based only on symptomatic cases should give similar results .

"Title: In Vitro Antiviral Activity of Circular Triple Helix Forming Oligonucleotide RNA towards Feline Infectious Peritonitis Virus Replication\nPassage: Study has shown that about 40-80% of cats are detected with FECV shedding in their faeces . About 12% of these FECV-positive cats have developed immune-mediated fatal FIP disease .

Transmission occurs mainly through direct contact between infected and susceptible cats; however, indirect transmission can also occur in the case of FCV, particularly within a cattery where secretions may contaminate cages, feeding and cleaning utensils or personnel . Reports from cats with URTD have revealed a prevalence ranging among 20-53% for FCV and 10-34% for FHV-1 .

Hepcidin not only shows antimicrobial activity against Gram-positive bacteria, Gram-negative bacteria and yeasts, but also functions as a principal iron regulatory hormone . Hepcidin binds to the iron export protein ferroportin and induces its internalization and degradation, which leads to decreased cellular iron export and increased intracellular iron retention . Because iron is an essential nutrient for all organisms, hepcidin also restricts the iron available to invading microbes, thereby enhancing the host defense against pathogens .

"Title: Silencing airway epithelial cell-derived hepcidin exacerbates sepsis-induced acute lung injury\nPassage: Hepcidin is a β-defensin-like antimicrobial peptide that is mainly produced by the liver. Hepcidin not only shows antimicrobial activity against Gram-positive bacteria, Gram-negative bacteria and yeasts, but also functions as a principal iron regulatory hormone . Hepcidin binds to the iron export protein ferroportin and induces its internalization and degradation, which leads to decreased cellular iron export and increased intracellular iron retention . Because iron is an essential nutrient for all organisms, hepcidin also restricts the iron available to invading microbes, thereby enhancing the host defense against pathogens . Furthermore, hepcidin can modulate the lipopolysaccharide -induced acute inflammatory response via",
"Title: Silencing airway epithelial cell-derived hepcidin exacerbates sepsis-induced acute lung injury\nPassage: washed in phosphate-buffered saline and incubated with a polymer horseradish peroxidase-conjugated secondary antibody for one hour. The sections were further incubated with Dako Liquid DAB Large-Volume Substrate-Chromogen System and counterstained with hematoxylin. Negative controls were included in all assays by replacing the rabbit anti-mouse hepcidin antibody with nonimmune rabbit antiserum. The immunostaining was evaluated using an Olympus BX-50 light microscope . The stain density was analyzed using the Image Pro-Plus 6.0 analysis system , and the level of hepcidin was measured as the integral optical density.",
"Title: Relationship between hepcidin and oxidant/antioxidant status in calves with suspected neonatal septicemia\nPassage: Hepcidin is a low molecular weight, antimicrobial peptide hormone and was first discovered in human urine . It is produced by the liver as a firstline response to inflammatory reactions and high Fe concentrations . Hepcidin plays a fundamental role in the regulation of Fe metabolism , which is a part of foundational cellular functions and thus of vital importance. On the other hand, by participating in redox reactions leading to the production of reactive oxygen species , Fe also causes oxidative stress. Therefore, Fe has been regarded as a potentially toxic element to cells . Fe also plays an",
"Title: Performance evaluation of antimicrobial peptide ll-37 and hepcidin and β-defensin-2 secreted by mesenchymal stem cells\nPassage: Hepcidin is bound to plasma alpha-2 macroglobulin . Evidence suggests that other cells may express the hepcidin mRNA at a much lower level than the hepatocytes; the biological significance of the extra hepatic production of hepcidin remains uncertain. Plasma hepcidin is freely treated through glomeruli and in animals with normal kidney activity it quickly passes through the urine. In addition, a part of hepcidin is cleansed through degradation along with ferritin ."

"Title: The Intranasal Application of Zanamivir and Carrageenan Is Synergistically Active against Influenza A Virus in the Murine Model\nPassage: One approach for a broad antiviral therapy is the creation of a protective physical barrier in the nasal cavity using carrageenan. Carrageenan is a high molecular weight sulfated polymer derived from red seaweed that has been extensively used in food, cosmetic and pharmaceutical industry and is generally recognized as safe by the FDA ). Three main forms of carrageenans are commercially used: kappa, iota and lambda. They differ from each other in the degree of sulfation, solubility and gelling properties . The antiviral mechanism of carrageenan is based on the interference with viral attachment; as a consequence, viral entry is",

"Title: Targeting the IL-22/IL-22BP axis enhances tight junctions and reduces inflammation during influenza infection\nPassage: To measure lung leak, the Evan's blue assay was used. Briefly, mice were injected intravenously with a 0.1% sterile solution of Evan's blue dye 30 min prior to sacrifice. The mouse paws and nose turning blue after injection verified dissemination of the dye visually. Evan's blue was measured in the BAL by measuring absorbance at 620 nm on a spectrophotometer.",

"Title: Visible Light-Responsive Platinum-Containing Titania Nanoparticle-Mediated Photocatalysis Induces Nucleotide Insertion, Deletion and Substitution Mutations\nPassage: The blue-white screen was originally developed as a screening technique for rapid and convenient recombinant bacteria detection in vector-based molecular cloning experiments . The method is based on the principle of α-complementation of the β-galactosidase gene lacZ; therefore, the plasmid should contain lacZα , whereas the E. coli strain must contain mutated lacZ with a deleted sequence . Here, the plasmid was transformed into competent host E. coli XL1-blue cells , which were then plated on LB agar plates containing 100 µg/mL ampicillin, 50 g/mL X-gal and 0.1 mM isopropyl β-D-1-thiogalactopyranoside . These plates were then incubated overnight at 37",
