"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: Novel protein chip for the detection of antibodies against infectious bronchitis virus\nPassage: demonstrated that when the positive serum was diluted 1:1000, the spot still turned blue . .",
"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",
"Title: Transcriptome networks identify mechanisms of viral and nonviral asthma exacerbations in children\nPassage: are colored red or blue , with color intensity corresponding to fold change. Modules whose expression was not significantly different are shown as points rather than squares to simplify the diagram."

"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: Text: D espite early reports , the premise that hand-wash sink traps can act as reservoirs of bacteria that cause nosocomial infections has been frequently overlooked. There has recently been an alarming increase in sink-related outbreaks worldwide, with many reports establishing an observational link . A sink often operates as an open conduit to wastewater in a patient care area that is often in the same room as the patient.",
"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: from a P-trap reservoir to a vulnerable hospitalized patient. IMPORTANCE Many recent reports demonstrate that sink drain pipes become colonized with highly consequential multidrug-resistant bacteria, which then results in hospital-acquired infections. However, the mechanism of dispersal of bacteria from the sink to patients has not been fully elucidated. Through establishment of a unique sink gallery, this work found that a staged mode of transmission involving biofilm growth from the lower pipe to the sink strainer and subsequent splatter to the bowl and surrounding area occurs rather than splatter directly from the water in the lower pipe.

"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: In summary, this work for the first time better models the mechanisms of spread of multidrug-resistant pathogens arising from the sink drain and infecting patients. Droplet dispersion from the P-trap does not happen directly. Rather it is a multistage process: dispersal originates from the strainer and/or the bowl after growth of the biofilm up from the microbial reservoir of the P-trap. We also demonstrate sink-to-sink transmission via a common sanitary pipe. This work could have implications for patient safety, infection control, and interventions as well as the design of future hospital plumbing systems to eliminate this mode of transmission to",
"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: Health care establishments often invest in desperate interventions to deal with nosocomial outbreaks. The preferred method for addressing most of the environmentrelated transmission is to employ enhanced cleaning using chemical and physical agents . Unfortunately, routine approaches are inefficient in completely eliminating drug-resistant Gammaproteobacteria in an inaccessible microbiologically active area such as a sink trap . The wet, humid, and relatively protected environment in a sink trap favors the formation of rich stable microbial communities . These communities will be exposed to liquids and waste that are discarded in a sink and may include antimicrobials, discarded beverages, soap, presumably pathogenic"

There has recently been an alarming increase in sink-related outbreaks worldwide, with many reports establishing an observational link . A sink often operates as an open conduit to wastewater in a patient care area that is often in the same room as the patient.",
"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: from a P-trap reservoir to a vulnerable hospitalized patient. IMPORTANCE Many recent reports demonstrate that sink drain pipes become colonized with highly consequential multidrug-resistant bacteria, which then results in hospital-acquired infections. However, the mechanism of dispersal of bacteria from the sink to patients has not been fully elucidated. Through establishment of a unique sink gallery, this work found that a staged mode of transmission involving biofilm growth from the lower pipe to the sink strainer and subsequent splatter to the bowl and surrounding area occurs rather than splatter directly from the water in the lower pipe. We have also demonstrated",
"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: In summary, this work for the first time better models the mechanisms of spread of multidrug-resistant pathogens arising from the sink drain and infecting patients. Droplet dispersion from the P-trap does not happen directly. Rather it is a multistage process: dispersal originates from the strainer and/or the bowl after growth of the biofilm up from the microbial reservoir of the P-trap. We also demonstrate sink-to-sink transmission via a common sanitary pipe. This work could have implications for patient safety, infection control, and interventions as well as the design of future hospital plumbing systems to eliminate this mode of transmission to",
"Title: Spread from the Sink to the Patient: In Situ Study Using Green Fluorescent Protein (GFP)-Expressing Escherichia coli To Model Bacterial Dispersion from Hand-Washing Sink-Trap Reservoirs\nPassage: Health care establishments often invest in desperate interventions to deal with nosocomial outbreaks. The preferred method for addressing most of the environmentrelated transmission is to employ enhanced cleaning using chemical and physical agents . Unfortunately, routine approaches are inefficient in completely eliminating drug-resistant Gammaproteobacteria in an inaccessible microbiologically active area such as a sink trap . The wet, humid, and relatively protected environment in a sink trap favors the formation of rich stable microbial communities . These communities will be exposed to liquids and waste that are discarded in a sink and may include antimicrobials, discarded beverages, soap, presumably pathogenic"

In Europe, the excess mortality rate associated with the 1918-1919 influenza pandemic has been estimated at 1.1%, or approximately an 86% increase in all-cause mortality . This pandemic rapidly spread in a series of pandemic waves that gripped the world beginning in early 1918 . However, according to results of various phylogenetic and molecularclock analyses, the initial circulation of the virus from avian or swine and other mammal species to humans may have occurred a few years earlier . Moreover, the",
"Title: Age-Specific Excess Mortality Patterns During the 1918–1920 Influenza Pandemic in Madrid, Spain\nPassage: . For instance, estimates of pandemic excess respiratory death rates have ranged from 6.1 per 10,000 for the Canary Islands to 169.7 per 10,000 for Burgos . Moreover, approximately 40% of between-province variation in cumulative excess death rates in Spain during 1918-1919 are explained by spatial factors, such as latitude, population density, and the proportion of children, have explained . However, in few of these analyses did researchers take into account a recrudescent wave in Spain, which peaked in Madrid in late December 1919 and in later months in the rest of Spain .",

Perhaps this pandemic outcome is associated with the fact that Spain was going through a demographic transition and experiencing elevated death rates that were only comparable to those of eastern Europe.

1624 | What was the death toll in the 1918-1919 Spanish Influenza epidemic? | [
"Title: Age-Specific Excess Mortality Patterns During the 1918–1920 Influenza Pandemic in Madrid, Spain\nPassage: The 1918-1920 influenza pandemic, or the so-called Spanish flu, was responsible for more than 50 million deaths worldwide . In Europe, the excess mortality rate associated with the 1918-1919 influenza pandemic has been estimated at 1.1%, or approximately an 86% increase in all-cause mortality . This pandemic rapidly spread in a series of pandemic waves that gripped the world beginning in early 1918 . However, according to results of various phylogenetic and molecularclock analyses, the initial circulation of the virus from avian or swine and other mammal species to humans may have occurred a few years earlier . Moreover, the",
"Title: Age-Specific Excess Mortality Patterns During the 1918–1920 Influenza Pandemic in Madrid, Spain\nPassage: . For instance, estimates of pandemic excess respiratory death rates have ranged from 6.1 per 10,000 for the Canary Islands to 169.7 per 10,000 for Burgos . Moreover, approximately 40% of between-province variation in cumulative excess death rates in Spain during 1918-1919 are explained by spatial factors, such as latitude, population density, and the proportion of children, have explained . However, in few of these analyses did researchers take into account a recrudescent wave in Spain, which peaked in Madrid in late December 1919 and in later months in the rest of Spain .",
"Title: Age-Specific Excess Mortality Patterns During the 1918–1920 Influenza Pandemic in Madrid, Spain\nPassage: We retrieved all death certificates from the Madrid Civil Registry to construct time series of deaths during the 1918-1920 influenza pandemic . Each record provides specific details of the deceased, including the date of death, age, and causes of death. For years 1917-1920, the registry holds a total of 70,061 death records . Cause-of-death information for each death record allowed us to extract data on deaths attributed to influenza and respiratory causes.",
"Title: Age-Specific Excess Mortality Patterns During the 1918–1920 Influenza Pandemic in Madrid, Spain\nPassage: Spain experienced one of the highest excess mortality rates during the 1918 influenza pandemic in Europe , although this country did not take part in World War I. Perhaps this pandemic outcome is associated with the fact that Spain was going through a demographic transition and experiencing elevated death rates that were only comparable to those of eastern Europe. Of note, the life expectancy in Spain was 41 years in 1910 and 40 years in 1920 ."

It has been demonstrated HTNV or ANDV infection could disrupt the interaction of β3 integrin with VEGFR2 and induce VEGFR2 hyper phosphorylation, which may enhance the permeability of infected endothelial cells by sensitizing them to VEGF .

"Title: Anxiety and Depression: Linkages with Viral Diseases\nPassage: the specific mechanisms can vary by viral illness. Mental conditions such as major depression can delay help-seeking or reduce the likelihood of detection of other health conditions including communicable diseases. 1 Depression and psychological stress have been shown to have a number of biological effects including reduced cell-mediated immunity and increased inflammatory processes. 3 A further issue is that some viral diseases can directly affect the brain and result in mood disorders or cognitive impairment. 1",
"Title: Respiratory Viral Infections in Exacerbation of Chronic Airway Inflammatory Diseases: Novel Mechanisms and Insights From the Upper Airway Epithelium\nPassage: Another mechanism that viral infections may use to drive acute exacerbations is the induction of vasodilation or tight junction opening factors which may increase the rate of infiltration. Infection with a multitude of respiratory viruses causes disruption of tight junctions with the resulting increased rate of viral infiltration. This also increases the chances of allergens coming into contact with airway immune cells. For example, IFV infection was found to induce oncostatin M which causes tight junction opening . Similarly, RV and RSV infections usually cause tight junction opening which may also increase the infiltration rate of eosinophils and thus worsening",

489 | How many deaths occur annually as a result of annual influenza epidemics? | [
"Title: Descriptive study of severe hospitalized cases of laboratory-confirmed influenza during five epidemic seasons (2010–2015)\nPassage: Influenza is an infectious disease affecting mainly upper respiratory tract worldwide. Influenza virus causes between three and five million severe cases and an estimated 250,000-350,000 deaths annually. In the European Union, there are between 40,000 and 220,000 annual deaths attributable to influenza. However, mortality is only the tip of the iceberg in terms of the disease burden, since influenza also causes a decrease in functional status and increased dependency in the elderly . Estimating the burden of disease caused by influenza is difficult because many cases do not require medical care, or no confirmatory laboratory tests are widely performed to",
"Title: Use of daily Internet search query data improves real-time projections of influenza epidemics\nPassage: Seasonal influenza remains an important infectious cause of morbidity and mortality . In the USA alone, estimates of annual incidence range from 9.2 million to 35.6 million cases, resulting in 140 000 to 710 000 hospitalizations and 12 000 to 56 000 deaths .",
"Title: Forecasting the 2013–2014 Influenza Season Using Wikipedia\nPassage: hospitalized from seasonal influenza complications, and 3,000-49,000 people die each year . The result is a significant public health and economic burden for the U.S. population .",
"Title: On Temporal Patterns and Circulation of Influenza Virus Strains in Taiwan, 2008-2014: Implications of 2009 pH1N1 Pandemic\nPassage: According to World Health Organization statistics, influenza occurs globally with an estimated annual attack rate of 5%-10% in adults and 20%-30% in children . These annual epidemics are estimated to result in approximately 3 to 5 million cases of severe illness worldwide and around 250 000 to 500 000 deaths, which is a major cause of losses in human lives and a grave global public health issue."

"Title: Hydroxychloroquine, a less toxic derivative of chloroquine, is effective in inhibiting SARS-CoV-2 infection in vitro\nPassage: Clinical investigation found that high concentration of cytokines were detected in the plasma of critically ill patients infected with SARS-CoV-2, suggesting that cytokine storm was associated with disease severity 12 . Other than its direct antiviral activity, HCQ is a safe and successful anti-inflammatory agent that has been used extensively in autoimmune diseases and can significantly decrease the production of cytokines and, in particular, pro-inflammatory factors. Therefore, in COVID-19 patients, HCQ may also contribute to attenuating the inflammatory response. In conclusion, our results show that HCQ can efficiently inhibit SARS-CoV-2 infection in vitro.

In 1996, Dr. Goodell observed that after adding Hoechst 33342 to a culture of bone marrow cells, a few cells did not accumulate dyes, and he claimed that these few cells were side population cells. Therefore, SP cells can be separated by fluorescence screening after the outflow of Hoechst 33342. Recently, SP cells have been identified in various normal tissues and tumor cells.

"Title: Virus-Vectored Influenza Virus Vaccines\nPassage: The general types of influenza vaccines available in the United States are trivalent inactivated influenza vaccine , quadrivalent influenza vaccine , and live attenuated influenza vaccine . There are three types of inactivated vaccines that include whole virus inactivated, split virus inactivated, and subunit vaccines. In split virus vaccines, the virus is disrupted by a detergent. In subunit vaccines, HA and NA have been further purified by removal of other viral components. TIV is administered intramuscularly and contains three or four inactivated viruses, i.e., two type A strains and one or two type B strains. TIV efficacy is measured by",

Despite advances in the development of antiviral drugs, a poor understanding of the immune mechanisms underlying viral FH has largely stalled the identification of effective clinical interventions. Fortunately, the recent development of an animal model of FH using murine hepatitis virus strain-3 infection has provided insights in understanding the pathogenesis and developing novel therapeutics for the disease .",
