"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.",
"Title: Design and Experimental Approach to the Construction of a Human Signal-Molecule-Profiling Database\nPassage: room for blood sampling. 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",

785 | How is Venezuelan equine encephalitis virus transmitted? | [
"Title: Treatment of Neuroterrorism\nPassage: Venezuelan equine encephalitis virus is an alphavirus that is most commonly found in Central and South America. It is transmitted to humans by mosquitoes. In case of a bioterrorist attack, the distribution would be made through aerosols . The virus usually leads to an initial severe febrile illness in nearly everyone exposed at 1 to 6 days after exposure.",
"Title: Evolution and spread of Venezuelan equine encephalitis complex alphavirus in the Americas\nPassage: within the VEE subtype, subtype II Everglades virus , which is found only in Florida, can cause neurologic disease in humans and equids . Subtype IIIA, Mucambo virus, also causes febrile disease in humans .",
"Title: Evolution and spread of Venezuelan equine encephalitis complex alphavirus in the Americas\nPassage: hundreds-of-thousands of cases over a period of months to a few years. Prior to the 1980s, VEE epizootics involving high case-fatality rates were frequently recorded. Because horses have been an important component of the local agricultural economies within many Latin American regions, VEE has often had a sizeable economic impact as well as a direct effect on public and veterinary health . Recent outbreaks during the 1990s in Venezuela, Colombia and Mexico have demonstrated the potential for VEEV to re-emerge periodically from enzootic progenitors . The emergence of VEEV into an epidemic/ epizootic form has been associated with specific mutations",
"Title: Evolution and spread of Venezuelan equine encephalitis complex alphavirus in the Americas\nPassage: climate change, which also increases the potential for other VEEV subtypes to spread northwards and establish enzootic transmission cycles. Although many VEE complex viruses have not been implicated in human disease, those that are associated with human disease can cause acute, often severe febrile illness that may progress to encephalitis, causing severe human morbidity and mortality . Patients who survive encephalitis are often left with permanent neurologic sequelae, and the cost for treatment and long-term care related to a single case can be several million dollars . In addition to VEEV , which cases the majority of the encephalitis cases"

"Title: Effect modification of environmental factors on influenza-associated mortality: a time-series study in two Chinese cities\nPassage: The results of stratification analysis by anomalies are shown in Additional file 1: Table S2 . The estimates were similar to those for the periods defined by absolute values of meteorological factors, in terms of magnitude and changing patterns. But the likelihood ratio tests showed more significant interaction for temperature or vapor pressure, and less for relative humidity.",
"Title: Effect modification of environmental factors on influenza-associated mortality: a time-series study in two Chinese cities\nPassage: There are several limitations in our study. Firstly, our study is based on 3 years of surveillance data which may not have enough power to allow assessment of exposureresponse curves for the effects of environmental factors. Nevertheless, our findings did suggest an increasing trend of influenza associated mortality risks across the periods of low, middle and high vapor pressure, although such findings may be applicable only to the warm climates. Secondly, we only investigated the effect modification of environmental factors through a simple interaction model, but there were other unadjusted factors, including host susceptibility and virulence of influenza strains.

"Title: Effect modification of environmental factors on influenza-associated mortality: a time-series study in two Chinese cities\nPassage: guinea pig experiments showed dramatically reduced transmission rates . In future, we may examine the seasonal variation in influenza effects in other cities to assess whether such a seasonal variation, if common in subtropical and tropical cities, is consistently determined by environmental factors, or by other factors such as host immunity and virus virulence. The results for the different age groups suggested that the modification effects of environmental factors may mainly lie in the elderly aged over 65 years, as the consistent increasing trend over the low to high vapor pressure periods was only observed in this age group.

"Title: Risk factors for severe acute lower respiratory infections in children – a systematic review and meta-analysis\nPassage: Hospitalization for acute lower respiratory infections in young children poses a substantial burden on health services, especially in developing countries. In spite of this, the evidence regarding the risk factors for this major burden of disease is in many cases sparse, of variable quality, and not generalizable. However, since the majority of these risk factors are potentially preventable, governments should consider what action can be taken to decrease the prevalence of these risk factors. This, along with increasing coverage of vaccines for Streptococcus pneumoniae and Haemophilus influenzae type B, should substantially decrease the burden of childhood pneumonia in developing countries.",
"Title: Determining the Provincial and National Burden of Influenza-Associated Severe Acute Respiratory Illness in South Africa Using a Rapid Assessment Methodology\nPassage: South Africa is a middle-income country, but there is great variation in socioeconomic status with some provinces that are more similar to low-income countries . This results in some populations within the country having a disproportionately higher level of exposure to risk factors for communicable disease. These include environmental risk factors, such as crowded living conditions and exposure to indoor air pollution, as well as biological risk factors, such as malnutrition and underlying infections . These risk factors may drive the burden of influenza in South Africa to be greater than other countries with similar income level . In particular,",
"Title: Risk factors for severe acute lower respiratory infections in children – a systematic review and meta-analysis\nPassage: Moreover, the odds ratio meta-estimates reported in this review should be useful for modeling the global, regional, and national estimates of severe ALRI if the national/regional prevalence of these risk factors are known . Future studies should investigate the role of poverty, HIV, and other risk factors currently classified \"likely\" or \"possible\" risk factors for ALRI, and should attempt to obtain more precise estimates of risk for \"definite\" risk factors by studying larger samples in diverse settings and by more careful measurement and analysis of possible confounding factors.",
"Title: Risk factors for severe acute lower respiratory infections in children – a systematic review and meta-analysis\nPassage: We identified 36 studies that investigated 19 risk factors for severe ALRI. Of these, 7 risk factors were significantly associated with severe ALRI in a consistent manner across studies, with the following meta-analysis estimates of odds ratios : low birth weight 3.18 , lack of exclusive breastfeeding 2.34 , crowding -more than 7 persons per household 1.96 , exposure to indoor air pollution 1.57 , incomplete immunization 1.83 , undernutrition -weight-for-age less than 2 standard deviations 4.47 , and HIV infection 4.15 ."

"Title: Virus contaminations of cell cultures – A biotechnological view\nPassage: controlled conditions led to the production of better quality animals especially in respect of virus infections . Van Wezel et al. could show, by performing serological tests on 18 captive-bred cynomolgous monkeys and 40 imported wild caught parent animals that most of the wild caught animals were positive for antibodies against herpes simplex B, parainfluenza 3, or measles virus, whereas two thirds of the captive bred animals were only positive for antibodies against rotaviruses. Twenty out of 36 imported animals were positive for foamy virus 1 antibodies whereas these antibodies were not observed in the animals bred in captivity .",
"Title: Model-Based Design of Growth-Attenuated Viruses\nPassage: Infections caused by viruses persistently threaten human health. For example, 40 million, 350 million, and 170 million people in the world are carrying human immunodeficiency virus type 1 , hepatitis B virus , and hepatitis C virus , respectively . Annually 5% to 15% of the global population is infected with influenza, resulting in 250,000 to 500,000 deaths . Protection against viral infections may be provided by inoculations with live-virus, killed-virus, or subunit vaccines. Live-virus vaccines offer advantages because they activate both humoral and cellmediated immunity, require only a single boosting, and generally provide longer immune protection than other forms",
"Title: Modified Vaccinia Virus Ankara Preferentially Targets Antigen Presenting Cells In Vitro, Ex Vivo and In Vivo\nPassage: Vaccination is the cornerstone control measure to reduce morbidity and mortality caused by infectious diseases. However, vaccination against hypervariable and emerging pathogens can be challenging. For example, seasonal influenza vaccines need to be updated almost annually to antigenically match emerging drift variant viruses and to maintain vaccine efficacy. Furthermore, in case of an emerging pandemic strain of influenza virus, timely production of a pandemic influenza vaccine has proven to be challenging 27, 28 .

591 | How is the the precursor form GPC processed, during virus maturation? | [
"Title: The lifecycle of the Ebola virus in host cells\nPassage: GP protein is synthesized in the endoplasmic reticulum as a precursor and transported along the classical secretory pathway from the ER via the Golgi apparatus to the plasma membrane. Precursor GP is processed by the acylation, oglycosylation, and maturation of N-glycans, and finally undergoes proteolytic cleavage by furin . Acylation is another posttranslational modification of viral GP, involved in particle formation, including virus assembly and budding. After those processes, GP is partially recruited to the late endosome to meet with VP40 for assembly and budding .",
"Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: During virus maturation, the precursor form GPC is processed using a membrane -bound protease into Gn and Gc, a cleavage that occurs, and appears to be signaled, after the conserved peptide signal WAASA at the C-terminal of Gn . Although the two proteins can be expressed independently through transfection, they can be retained in the wrong cellular compartment ; they thus must be co-expressed to allow them stability so that the two can be assembled correctly in the Golgi .",
"Title: The lifecycle of the Ebola virus in host cells\nPassage: Following endocytosis, the next steps consist of the uncoating and fusion of the viral membrane with the endosomal membranes. Precursor GP is cleaved by the host enzyme, furin in the Golgi apparatus, resulting in GP1, GP2, and additional proteins, including sGP, Δ-peptide, and ssGP . GP2 is critical for membrane fusion, as it's composed of five domains: 1) a fusion loop; 2) an N-terminal heptad repeat region; 3) a C-terminal heptad repeat region; 4) a transmembrane region; and 5) a short cytoplasmic tail . The glycan cap of GP1 can interact with the internal fusion loop of GP2 to restrict",
"Title: Vesicular Transport of Progeny Parvovirus Particles through ER and Golgi Regulates Maturation and Cytolysis\nPassage: Furthermore, other viruses become processed after assembly. For instance, assembled polioviruses present in autophagosomes, were shown to mature upon acidification of these vesicles prior to their fusion with lysosomes. This acidification induces the cleavage of poliovirus capsid proteins, an essential step for these virions to gain full infectivity . Interestingly, MVM and H-1PV virions were shown to colocalize with the late endosomal/lysosomal marker Lamp2 . This leads us to speculate that the maturation of these viruses may involve the induction of additional post-assembly capsid modifications in these compartments besides the above-mentioned Golgi-associated phosphorylations."

953 | Why are adenovirus vectors most attractive? | [
"Title: Viral vector-based influenza vaccines\nPassage: Recombinant adenoviruses have attractive properties to serve as vaccine vectors: high titer stocks can be grown, genes of interest can easily be inserted into the stable viral genome, long-term storage at 4 degrees is possible and rAd infects a variety of hosts, tissues and cell types. 184 Furthermore, rAd can even induce robust immune responses when administered orally or intra-nasally, potentially bypassing pre-existing immunity against the vector. 184 Finally, even replicationdeficient rAd are known to be immunogenic; adenovirus 5 is a replication-deficient vector that has been evaluated for gene delivery, anti-cancer therapy and as an infectious disease vaccine. An overview",
"Title: Virus-Vectored Influenza Virus Vaccines\nPassage: Adenovirus vectors are attractive as vaccine vectors because their genome is very stable and there are a variety of recombinant systems available which can accommodate up to 10 kb of recombinant genetic material . Adenovirus is a non-enveloped virus which is relatively stable and can be formulated for long-term storage at 4 °C, or even storage up to six months at room temperature . Adenovirus vaccines can be grown to high titers, exceeding 10 1° plaque forming units per mL when cultured on 293 or PER.C6 cells , and the virus can be purified by simple methods . Adenovirus vaccines",
"Title: HIV Antigen Incorporation within Adenovirus Hexon Hypervariable 2 for a Novel HIV Vaccine Approach\nPassage: Adenoviral vectors have been used for a variety of vaccine applications including cancer and infectious diseases . Ad vectors have been utilized as vaccine vectors because of several attributes. This broad utility profile has derived from several key attributes: the viral genome is readily manipulated allowing derivation of recombinant viruses; replication-defective Ads can be derived and propagated easily in complementing cell lines making production of large scale vaccines feasible; Ads infect a broad range of target cells ; they possess a large gene delivery payload of up to 8kb; and the vector can achieve unparalleled levels of in vivo gene",
"Title: Pre-existing immunity against vaccine vectors – friend or foe?\nPassage: both CD4 + and CD8 + T cell responses . The adenovirus vector is another of the most widely evaluated vectors to date to express heterologous antigens, due to ease of production, safety profile, genetic stability, the ease of DNA genome manipulation, and the ability to stimulate both innate and adaptive immune responses and induce both T and B cell responses . They have been extensively examined as a delivery vector in several preclinical and clinical studies for infectious diseases such as anthrax, hepatitis B, human immunodeficiency virus -1, influenza, measles, severe acute respiratory syndrome , malaria and tuberculosis M."

"Title: Responding to the COVID-19 pandemic in complex humanitarian crises\nPassage: Populations affected by humanitarian crises are expected to be particularly susceptible to COVID-19, the disease caused by SARS-CoV-2, due to displacement, crowded housing, malnutrition, inadequate water, sanitation, and hygiene tools, and stigmatization. Disease outbreaks further reduce access to limited healthcare, which is increasingly disrupted by attacks on health facilities and the persistent overburdening of health systems.

"Title: Responding to the COVID-19 pandemic in complex humanitarian crises\nPassage: As the international community responds to SARS-CoV-2, public health authorities in humanitarian crises begin at a disadvantage to enact appropriate infection control to prevent transmission in healthcare settings, identify infectious cases, administer supportive care and novel treatments for the seriously ill, and trace contacts. These standard public health measures are particularly difficult to perform in humanitarian settings. For example, limited public health, laboratory, and primary care services represent a barrier to testing. Providing the limited healthcare worker cadre with appropriate training and personal protective equipment, and ensuring a continuous supply chain for such, is a challenge in all settings, exacerbated",

Many genomic factors such as gene length, GC-content, recombination rate, gene expression level, or modulation in the genetic code are associated with CUB in different organisms .

"Title: No credible evidence supporting claims of the laboratory engineering of SARS-CoV-2\nPassage: Currently, there are speculations, rumours and conspiracy theories that SARS-CoV-2 is of laboratory origin. Some people have alleged that the human SARS-CoV-2 was leaked directly from a laboratory in Wuhan where a bat CoV was recently reported, which shared ∼96% homology with the SARS-CoV-2 . However, as we know, the human SARS-CoV and intermediate host palm civet SARSlike CoV shared 99.8% homology, with a total of 202 single-nucleotide variations identified across the genome . Given that there are greater than 1,100 nt differences between the human SARS-CoV-2 and the bat RaTG13-CoV , which are distributed throughout the genome in a",

"Title: Mortality among patients with tuberculosis requiring intensive care: a retrospective cohort study\nPassage: Of them, 62 had ARF and required MV. The mean age of all patients was 43.2 ± 14.1 years and males slightly outnumbered female patients . A history of previous TB was present in only 6 patients . Comorbid illnesses were identified in 58 patients, with coinfection with HIV being the most common, present in 46 patients. The median CD4/ mm 3 count of these patients was 83 , and only 6 were receiving highly active anti-retroviral therapy at the time of hospitalization.

Passive case finding is the routine practice in developing countries where sputum microscopy is performed to identify TB cases among people with persistent cough. A large proportion of TB cases may be missed using this method as 53% of bacteriologically confirmed cases and 45% sputum positive cases in this study had no persistent cough but were identified through abnormal CXRAY. Nearly half of bacteriologically confirmed cases reported no symptoms in the last six months. This finding, although initially surprising, is consistent with reports",
"Title: Six-month survival of critically ill patients with HIV-related disease and tuberculosis: a retrospective study\nPassage: No aspect of TB diagnosis or treatment was different in survivors or nonsurvivors. Twenty-two pulmonary TB cases and 22 disseminated TB cases were equally distributed between the 2 groups . Tuberculosis was diagnosed from respiratory samples in the majority of cases. Thirty-two patients were diagnosed through direct visualization of the bacillus using the Ziehl-Neelsen technique ; the diagnosis was only made through culture of respiratory specimens in 5 patients. Bacteremia due to Mycobacterium tuberculosis was found in 6 patients. Eleven patients required invasive procedures for TB diagnosis, such as organ biopsy. The main TB regimens prescribed were per oral or"

"Title: Sounding the Alarm: Health in the Anthropocene\nPassage: Another important aspect of limits to growth is the increasing scarcity of resources, including the scarcity of affordable energy for use by industry, individuals and households. This aspect has received some public health attention, including a special issue in the American Journal of Public Health . In recent years, the price of oil has fallen , leading some commentators to argue that such concerns are overstated. However, few experts argue that the current comparatively low price of oil can be long sustained.",
"Title: Sounding the Alarm: Health in the Anthropocene\nPassage: Other forms of worsening resource scarcity include of phosphate, rare earths, helium and some metals. Additional aspects include a limit to the growth of crop yields , falling returns to increasing complexity , and imperfect co-operation. See Butler, 2015, for further review .",
"Title: Local risk perception enhances epidemic control\nPassage: Given infinite resources, all three of the decision paradigms would markedly diminish an emerging outbreak. However, interventions may be constrained by limited supplies or lack of population access to medical countermeasures, such as vaccines or antimicrobials. Even social distancing measures, such as self-isolation, may be limited by economic necessity-the need to go to work, school or daycare-or care-giving obligations for extended family. While such limitations should be formally analyzed, our simple analysis suggests that the best paradigm for averting infections also requires the fewest resources. For example, for a flu-like R 0 of two, compare the local count strategy, where",
"Title: Sounding the Alarm: Health in the Anthropocene\nPassage: This dilemma illustrates a less appreciated limit to growth. On the one hand, there may not be enough accessible, easily recoverable oil to fuel the global economy for more than a few more decades. But even if there is, the global capacity to safely absorb the carbon emissions released by the burning of this oil is itself critically limited. There is growing academic recognition, and also from some in business that much of the world's oil resources are effectively unburnable , or they would be in a world that prioritises the avoidance of highly dangerous climate change and the acceleration"

We established a cohort, collected baseline samples, monitored donors for symptoms, and collected follow-up samples. Banked samples were used to characterize pre-existing antibody and T-cell immunity cross-reactive with the pH1N1 virus and responses to infection. The relative mildness of the pandemic was fortunate for public health but resulted in relatively few infections in this cohort. We characterize baseline donor T-cell and antibody responses reactive with pH1N1 plus certain follow-up parameters.",

In contrast, the telephone-based study of Rubin et al. employed a random-digit-dial sampling design, allowing a more representative sample of the general UK population, but their sample was only 997 respondents and the survey was undertaken after media attention had abated, beginning 8 May 2009. Nonetheless, the results reported in this paper are largely congruent with our own results and we see the studies as strongly complementary."

"Title: Chest radiographic data acquisition and quality assurance in multicenter studies\nPassage: Recruitment of study subjects began in May 1990 and continued through January 1994, with follow-up continuing through January 1997. At the time of this report, 3,057 chest radiographs had been performed on the children enrolled in this study.",
"Title: The Trojan Chicken Study, Minnesota\nPassage: The study design was further limited in that we did not account for time after exposure when photographs were taken. Since participants could drop by any time of the day, the time after exposure and duration of exposure likely varied between participants. In both the feasibility and pilot studies, the return rate was low, and tracking down participants was difficult. If similar studies are conducted in the future, a reward system might be used to increase compliance.",

"Title: A super-spreading ewe infects hundreds with Q fever at a farmers' market in Germany\nPassage: Text: Q fever is a worldwide zoonosis caused by Coxiella burnetii , a small, gram-negative obligate intracellular bacterium. C. burnetii displays antigenic variation with an infectious phase I and less infectious phase II. The primary reservoir from which human infection occurs consists of sheep, goat and cattle. Although C. burnetii infections in animals are usually asymptomatic, they may cause abortions in sheep and goats . High concentrations of C. burnetii can be found in birth products of infected mammals . Humans frequently acquire infection through inhalation of contaminated aerosols from parturient fluids, placenta or wool . Because the infectious dose",
"Title: Emerging Infections and Pertinent Infections Related to Travel for Patients with Primary Immunodeficiencies\nPassage: C. burnetii is a highly pleomorphic Gram-negative coccobacillus and the causative agent of Q fever. Q fever is a zoonosis, and the most common reservoirs are cattle, sheep, and goats but many other animals can be infected by C. burnetii . When infected, these domestic animals can shed the organism in urine, feces, milk, and especially birth products. The pathogen survives within the phagolysosome of host cells, and a spore stage has been described. This spore stage explains the ability of C. burnetii to survive in unfavorable environmental conditions, and it can be an environmental risk for months to years",
"Title: A super-spreading ewe infects hundreds with Q fever at a farmers' market in Germany\nPassage: is very low and C. burnetii is able to survive in a spore-like state for months to years, outbreaks among humans have also occurred through contaminated dust carried by wind over large distances .",
"Title: A super-spreading ewe infects hundreds with Q fever at a farmers' market in Germany\nPassage: adults and children was estimated as 20% and 3%, respectively, 25% of cases were hospitalized. The ewe that had lambed as well as 25% of its herd tested positive for C. burnetii antibodies. CONCLUSION: Due to its size and point source nature this outbreak permitted assessment of fundamental, but seldom studied epidemiological parameters. As a consequence of this outbreak, it was recommended that pregnant sheep not be displayed in public during the 3trimester and to test animals in petting zoos regularly for C. burnetii."

490 | Is coinfection common in influenza infection? | [
"Title: Epidemiology and clinical characteristics of hospitalized patients with pandemic influenza A (H1N1) 2009 infections: the effects of bacterial coinfection\nPassage: In conclusion, our study suggests that bacterial coinfection is not uncommon in H1N1 infected patients and laboratory investigations should go beyond establishing a viral cause alone. Bacterial coinfection was more frequently seen in the older age group and was associated with higher rates of complications. As adjunct to clinical findings, clinicians need to have a high index of suspicion if neutrophilia was identified on admission as it may denote bacterial coinfection. A larger scale study will be useful to further confirm our findings.",
"Title: Severe novel influenza A (H1N1) infection in cancer patients\nPassage: In our study, we detected bacterial coinfection in seven of the eight patients. The CDC reported that 29% of fatal cases in the United States presented at least one bacterial coinfection . Mauad et al. found evidence of bacterial coinfection in 38% of fatal cases in Sao Paulo.",
"Title: Epidemiology and clinical characteristics of hospitalized patients with pandemic influenza A (H1N1) 2009 infections: the effects of bacterial coinfection\nPassage: Forty-five patients had lower respiratory tract specimens sent for bacterial cultures. The 5 patients without these specimens were children who had difficulty in producing respiratory secretions, however, they appeared generally well with no evidence of pneumonia. Blood cultures were performed in 23 patients and Mycoplasma pneumoniae serology in 27 patients . Of the 50 H1N1 patients, 17 were coinfected with a second respiratory pathogen; 14 bacterial and only 3 viral. Mycoplasma pneumoniae was the commonest bacterial coinfection followed by Staphylococcus aureus , Klebsiella pneumoniae , Streptococcus pneumoniae , Moraxella catarrhalis , Pseudomonas aeruginosa , Streptococcus pyogenes and Streptococcus agalactiae .",
"Title: Epidemiology and clinical characteristics of hospitalized patients with pandemic influenza A (H1N1) 2009 infections: the effects of bacterial coinfection\nPassage: The bacterial coinfection rate of 28% amongst our H1N1 hospitalized patients was higher compared to other studies . A large laboratory-based study in the United States demonstrated comparable bacterial coinfection rates to our study with similarly very low frequency of viral copathogen detection . Whilst our finding concurred with several studies that showed H1N1 infections having a predilection for younger patients, patients > 50 years had higher risk of bacterial coinfection in our study."
