"Title: Unified feature association networks through integration of transcriptomic and proteomic data\nPassage: Network centrality in biological networks is an indicator of the importance of the node to the function of the network . Pathways with higher centrality in host response networks may be more important to the host response and/or may be more coordinated in terms of their activity. To that end, the centrality of features in KEGG pathways was compared between each network to identify functions that may have higher or lower centrality in an antibody vs. receptor-mediated network. We used betweenness, the number of paths through a network that pass through the gene in question, as a measure of centrality.",
"Title: Neighborhood Properties Are Important Determinants of Temperature Sensitive Mutations\nPassage: Multiple measures can improve the confidence in performance evaluation. We calculated five measures to evaluate the perfor-mance of features and TS prediction models from cross-validations. To compare the five measures, we computed the Pearson correlation and mutual information between every pair of the five measures across all 133 individual feature-based classifiers . Pearson correlation is only sensitive to a linear relationship between two variables while mutual information is capable of detecting non-linear relationships. We found that AUC and DD had the best concordance according to mutual information and the third best concordance according to the Pearson correlation. Both measures consider",
"Title: Neighborhood Properties Are Important Determinants of Temperature Sensitive Mutations\nPassage: Next, we were interested in testing the predictive power of sequence and structure features. The ''sequence features'' model contained features calculated from sequence information only, while the ''structure features'' model had features derived from the protein crystal structure. The ''all features'' model combined sequence and structure features. The performance of the ''all features'' model was slightly better than that of the ''structure features'' model, while the ''structure features'' model performed better than the ''sequence features'' model . This suggests that structure-based features have higher predictive power than sequence-based features in differentiating TS mutations from neutral mutations. Nevertheless, the results demonstrated",
"Title: Neighborhood Properties Are Important Determinants of Temperature Sensitive Mutations\nPassage: As shown in Figure 6A , the ROC curve of the ''all features'' model is biphasic. True positive rates are three-fold of false positive rates when applying thresholds greater than 0.5, while true positive rates are less than two-fold of false positive rates when applying thresholds less than 0.5. Although the AUC value is slightly lower than those of leave-one protein-out , the lower left portion of the ROC curve is comparable with those, suggesting our top-ranked predictions are particularly accurate.

"Title: Identifying Locations with Possible Undetected Imported Severe Acute Respiratory Syndrome Coronavirus 2 Cases by Using Importation Predictions,\nPassage: To identify locations reporting fewer than predicted imported SARS-CoV-2 infected cases, we fit a model to data from 49 locations outside mainland China with high surveillance capacity according to the GHS Index . Among these, 17 had high travel connectivity to Wuhan and 32 have low connectivity to Wuhan. We considered locations to be countries without any position on territorial claims. We performed a Poisson regression by using the cumulative number of imported-and-reported SARS-CoV-2 cases in these 49 countries and the estimated number of daily airline passengers from the Wuhan airport. We then compared predictions from this model with imported-and-reported"

In total, only 53 swabs, representing 24% of the sample, remained without etiology with negative multiplex PCR results all along the year. Multiple hypotheses can explain this result: a poor quality of swabs, preventing from identifying a pathogen, noninfectious causes or other pathogens not included in the multiplex PCR.

"Title: Etiology of Influenza-Like Illnesses from Sentinel Network Practitioners in Réunion Island, 2011-2012\nPassage: Among the 148 swabs initially negative for influenza because not previously tested for any other viruses, the study found an etiology for 95 swabs. In total, only 53 swabs, representing 24% of the sample, remained without etiology with negative multiplex PCR results all along the year. Multiple hypotheses can explain this result: a poor quality of swabs, preventing from identifying a pathogen, noninfectious causes or other pathogens not included in the multiplex PCR. However, we couldn't test the negative swabs for RNAse P, a marker of human cells, which could provide a modicum of assurance that the swab contained human",
"Title: Pilot study of participant-collected nasal swabs for acute respiratory infections in a low-income, urban population\nPassage: Of the 29 swabs received, 18 had a corresponding research swab that was positive for a respiratory pathogen. Seven corresponding self-swabs were concordant with the positive research swabs for influenza, and eight corresponding self-swabs were concordant with the research swab for noninfluenza pathogens . The kappa statistic between research and self-swab was 0.84. There were no differences in demographic variables, including education level or days between drop-off and receipt of swabs, among participants whose self-and research-staff obtained swabs correlated versus those whose swabs did not correlate . Of the self-swab samples that had a corresponding positive research swab, the longest",
"Title: Etiology of Influenza-Like Illnesses from Sentinel Network Practitioners in Réunion Island, 2011-2012\nPassage: Among the 250 randomly-selected swabs, 26 were not available anymore as they were sent to Influenza Reference Center for confirmation and characterization of the pathogenic agent. According to the sensitivity of the assay two samples could be discordant results between Influenza PCR initially realized and Multiplex PCR. Thus they were deleted from the analysis: one is positive for Influenza in singleplex and negative for all tested pathogens in multiplex and one is positive for Influenza in singleplex and positive for PIV2 in multiplex. In total, 222 analyses were considered. Moreover, 53 samples were negative for all analyzed respiratory pathogens and",

On the other hand, 272 sick reports could not be merged to nasal swabs. Apart from the same issue of timing, this fact might also be explained by certain symptoms reported. The absence of a nasal sample correlates well with the presence of vomiting and the absence of runny nose. Further details on specimen results can be found in our Eurosurveillance paper . Briefly, when analyzing the seasonality, we found that the peak in the number of returned swabs was reached in the last week of September 2011, but"

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.

Parvovirus B19 has been described to cause encephalopathy in sickle cell patients. It is associated with aplastic anemia. It caused punctate areas of hemorrhages in the basal ganglia, periventricular white matter, and mainly along the posterior parietal cortex. This was attributed to parvovirus B19-induced vasculitis . In our patient,",
"Title: Acute Hemorrhagic Encephalitis Responding to Combined Decompressive Craniectomy, Intravenous Immunoglobulin, and Corticosteroid Therapies: Association with Novel RANBP2 Variant\nPassage: Several differential diagnoses of acute encephalopathy in a patient with sickle cell anemia can be considered. An infectious encephalitis, including herpes encephalitis, was ruled out by blood and CSF bacterial and viral cultures and negative HSV I/ II PCR. Nasopharyngeal aspirate was negative for viruses. Some infections have been previously associated with necrotizing encephalitis such as Influenza A . SCD patients are prone to ischemic or hemorrhagic strokes . Primary hemorrhagic stroke is uncommon in pediatric SCD.

Finally, acute encephalitis has been observed in SCD patients in the context of arterial hypoxemia from fat embolism, pulmonary embolism, sudden anemia, or acute chest syndrome due to pneumonia . This was ruled out as the patient did not have clinical or radiological signs of acute chest syndrome or embolism and there was no arterial hypoxemia.",
"Title: MLKL Mediated Necroptosis Accelerates JEV-Induced Neuroinflammation in Mice\nPassage: Japanese encephalitis virus is the most prevalent cause of viral encephalitis worldwide. More than 67,900 cases of JE are reported annually, among which approximately 30% are fatal and 50% suffer from permanent neuropsychiatric sequelae . JEV infection causes devastating and fatal neuroinflammation characterized by neuronal destruction accompanied with intense microgliosis, strogliosis, and production of various inflammatory cytokines . Neurons can be destroyed directly by JEV infection and indirectly by inflammation mediated cytotoxicity . Then the massive neuronal death contributes to the progression and deterioration of Japanese encephalitis ."

Furthermore, due to the concise format of medical records, only limited data could be retrieved for this audit. For example, information on whether patients received mechanical ventilation; the volume of fluids; and drugs was not available. According to anecdotal evidence, 99% of all admissions are mechanically ventilated; however, the lack of data to support this precludes us stating this as a fact. Other ICU-relevant data would have allowed better description of the study population. More",
"Title: Challenges in developing methods for quantifying the effects of weather and climate on water-associated diseases: A systematic review\nPassage: The lack of inclusion of relevant factors in the methods was the most common limitation acknowledged by the authors. These included: spatial and socio-economic heterogeneity, seasonality, changing immunity, and other environmental drivers. In almost 20% of papers, the authors identified reporting bias as a key limitation. Examples of reporting bias were: sample collections not properly designed ; voluntary internetbased survey reflecting survey respondents' idiosyncrasies; and health-seeking behaviours and socio-economic factors affecting access to health facilities.",
"Title: Early and dynamic alterations of Th2/Th1 in previously immunocompetent patients with community-acquired severe sepsis: a prospective observational study\nPassage: There are several potential limitations. This was a single-centre study. Data collection was limited to variables available during usual care and resulted in an imbalance between groups. Besides, among 338 severe sepsis patients admitted to our centre during 2-year study period, most were excluded for hospital-acquired sepsis, diagnosis of tumour and receipt of chemotherapy or corticosteroid, resulting in enrolling 71 patients, which might bring enrolment bias. Another limitation of this study is that the exact time of severe sepsis onset could not be precisely determined, though we have defined the onset to be the time recordable manifestation or laboratory findings",
"Title: Descriptive study of severe hospitalized cases of laboratory-confirmed influenza during five epidemic seasons (2010–2015)\nPassage: A limitation to this study is that only SHCLCI cases were recorded during the study period.

The system identifies the epidemiological and virological characteristics of severe forms of influenza that show changes in their virulence, but comparison between severe and non-severe cases is not feasible. The proportion of SHCLCI cases admitted to ICU and CFRs are potentially higher than other surveillance systems that monitor all hospitalised cases of confirmed influenza.

The higher HIV-1 infection rate of HIVIGLOB-treated infants persisted throughout six months of follow-up, although differences at later time points were not statistically significant.

The UPR also decreases protein load by increasing production of the ERAD machinery that degrades misfolded proteins . Finally, the UPR reduces protein load through the attenuation of protein translation .

Under homeostatic condition, the ER luminal domains of these sensor proteins are inactive, due to association with glucose regulating protein 78 . GRP78 has a high affinity for misfolded and unfolded proteins: when luminal load of misfolded protein increases, GRP78 is released from the ER stress sensors, which are then free to initiate downstream signalling outside the ER."

"Title: Interactome analysis of the lymphocytic choriomeningitis virus nucleoprotein in infected cells reveals ATPase Na(+)/K(+) transporting subunit Alpha 1 and prohibitin as host-cell factors involved in the life cycle of mammarenaviruses\nPassage: The cardiac glycoside ouabain is an inhibitor of ATP1A1 that has been used to treat congestive heart failure in European countries . The PHB inhibitor rocaglamide is a flavagline from an Aglaia tree used in traditional Chinese medicine that has potent anticancer activity . To examine whether pharmacological inhibition of ATP1A1 or PHB inhibited LCMV multiplication, we pretreated human , nonhuman primate , and rodent cells with ouabain or rocaglamide and infected them with rLCMV/eGFP . Ouabain treatment resulted in a strong dosedependent inhibition of eGFP expression in infected human-and nonhuman primate cells, but did not affect eGFP expression intensity",

"Title: Haunted with and hunting for viruses\nPassage: Tan and colleagues specifically focused on the newly-emerged MERS-CoV. The virus was identified in 2012 in the Middle East with some exported cases to Europe. In 2013 the virus has been re-emerging and expanding its borders to more European countries. In the initial diagnosis, the pan-coronavirus real-time reverse transcription polymerase chain reaction assay played a very important role for the identification of the causative agents. By using this method, scientists detected an expected-size PCR fragment for the corresponding conserved region of ORF1b of the replicase gene of a coronavirus. This is another example that molecular biology methods played for the",

What role maternal camel antibody might play in delaying infection of calves remains unknown . Juvenile DCs appear to host active infection more often than adult DCs and thus the sacrificial slaughter of DCs, which must be five years of age or older , may not be accompanied by significant risk of exposure to infection. In contrast to earlier results, slaughterhouse workers who kill both younger and older",

However, MERS-CoV infection frequency is reportedly much lower than is the widespread and frequent habit of eating, drinking and preparing DC products. Daily ingestion of fresh unpasteurized DC milk is common among the desert Bedouin and many others in the KSA. DC urine is also consumed or used for supposed health benefits. Despite camel butchery being a local occupation, neither butchers nor other at-risk groups are identifiable among MERS cases; this may simply be a reporting issue rather than an unexplainable absence of MERS.

All nine DC in the owner's herd, serially sampled, reacted in a recombinant S1 antigen ELISA, with the two animals that had been RT-rtPCR positive showing a small, verifiable rise in antibody titre .

"Title: Potential Rapid Diagnostics, Vaccine and Therapeutics for 2019 Novel Coronavirus (2019-nCoV): A Systematic Review\nPassage: There are eleven studies that focus on SARS-CoV diagnostic testing . These papers described diagnostic methods to detect the virus with the majority of them using molecular testing for diagnosis. Comparison between the molecular test and serological test showed that the molecular test has better sensitivity and specificity. Hence, enhancements to the current molecular test were conducted to improve the diagnosis. Studies looked at using nested PCR to include a pre-amplification step or incorporating N gene as an additional sensitive molecular marker to improve on the sensitivity .",
"Title: Potential Rapid Diagnostics, Vaccine and Therapeutics for 2019 Novel Coronavirus (2019-nCoV): A Systematic Review\nPassage: Serological testing such as ELISA, IIFT and neutralization tests are effective in determining the extent of infection, including estimating asymptomatic and attack rate. Compared to the detection of viral genome through molecular methods, serological testing detects antibodies and antigens. There would be a lag period as antibodies specifically targeting the virus would normally appear between 14 and 28 days after the illness onset . Furthermore, studies suggest that low antibody titers in the second week or delayed antibody production could be associated with mortality with a high viral load. Hence, serological diagnoses are likely used when nucleic amplification tests are",
"Title: Potential Rapid Diagnostics, Vaccine and Therapeutics for 2019 Novel Coronavirus (2019-nCoV): A Systematic Review\nPassage: The first validated diagnostic test was designed in Germany. Corman et al. had initially designed a candidate diagnostic RT-PCR assay based on the SARS or SARS-related coronavirus as it was suggested that circulating virus was SARS-like. Upon the release of the sequence, assays were selected based on the match against 2019-nCoV upon inspection of the sequence alignment. Two assays were used for the RNA dependent RNA polymerase gene and E gene where E gene assay acts as the first-line screening tool and RdRp gene assay as the confirmatory testing. All assays were highly sensitive and specific in that they did",
"Title: Diagnosis of influenza viruses with special reference to novel H1N1 2009 influenza virus\nPassage: There is no perfect test for the diagnosis of infl uenza. Virus culture, the present 'gold-standard test' is not 100% sensitive and does not provide results in a time-frame that allows optimal use of potentially effective antiviral treatment. Although rapid diagnostic tests provide results in less than 30 minutes, they are signifi cantly less sensitive and do not differentiate between different subtypes of infl uenza A virus. Rapid testing is only offered after the fi rst culture-confi rmed cases of infl uenza are reported from the community. Molecular assays; reverse transcriptase polymerase chain reaction and real-time RT-PCR targeting conserved regions"

"Title: Design and Experimental Approach to the Construction of a Human Signal-Molecule-Profiling Database\nPassage: away from hospitals . The subjects for this investigation were randomly selected and unfiltered. The time period of each group was consistent and was evenly distributed in two weeks. We made further inquiries 189 amicable interviewees who were willing to take the SMP tests about their background, as well as the privacy protection in SMP data. The patients were fully informed before the voluntary agreements for SMP tests were signed. The researchers obtained the respective remaining samples from nurses after the ordinary blood tests were performed. No extra sampling of blood was performed in this study.",

Our researchers were permitted to wait in the room and give the patients suggestions to permit the additional SMP tests accompanied by their original blood tests. The data acquisition was performed in a passive way, i.e., the participators were randomly involved in. We orally interviewed the patients, doctors and nurses regarding their attitude towards the SMP test. The investigators for survey studies were divided into two groups: one group interviewed the people who will get their blood tested in the blood-collection room of hospitals, whereas the other group randomly interviewed the pedestrians in city streets far",
