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."

673 | What type of cells form the intestinal mucosal barrier? | [
"Title: Immune regulation of the unfolded protein response at the mucosal barrier in viral infection\nPassage: The intestinal epithelial barrier forms a selectively permeable immunologically tolerant but alert barrier between the sterile inside and microbe-laden lumen.",
"Title: The Interaction of the Gut Microbiota with the Mucus Barrier in Health and Disease in Human\nPassage: of this system is apparent with the identification of different types of Goblet cells, which synthesize and secrete the mucus along the crypt in the human colon. Indeed a \"sentinel\" Goblet cell has been identified, positioned at the top of each colonic crypt. Endocytosis of TLR generates MUC2 secretion, together with an intercellular gap junction signal, which induces MUC2 secretion in adjacent Goblet cells and thus regulates the entry of bacteria into the crypt .",
"Title: The Interaction of the Gut Microbiota with the Mucus Barrier in Health and Disease in Human\nPassage: The stability of the mucus barrier and the innate defense mechanisms rely on the secretion of intact, gel forming mucus and the availability of mucosal immune proteins, including immunoglobulins and the trefoil factor peptides. Together these factors normally ensure mucosal cell integrity and epithelial homeostasis through restitution and regeneration processes. Part of the risk is linked to the immature state of the mucosa at this very early stage of life. A role for the mucins in the pathogenesis of NEC is indicated by the depletion of Goblet cells seen in the mucosa of neonates with NEC and this is expected",
"Title: Immune regulation of the unfolded protein response at the mucosal barrier in viral infection\nPassage: homeostasis Similar to intestinal mucosal epithelial cells, lung epithelial cells have developed many defence mechanisms to deal with environmental exposures. Increasing evidence shows that the UPR pathways interact with the recognition and handling of exogenous threats, like viruses. 44 The continuous epithelium in the airways acts as a physical barrier to keep the underlying immune system separated from exogenous air-borne pathogens. Ciliated cells continuously clear inhaled matter trapped by the mucus layer. Respiratory goblet cells synthesise and secrete the mucins, MUC5B and MUC5AC rather than MUC2.

"Title: Timing and causes of death in septic shock\nPassage: ICU also directly resulted from end-of-life decisions in 36 patients with fixed multiple organ failure for whom the treating physicians were convinced that meaningful recovery was not possible. Therefore, extensive diagnostic procedures were not carried out in such settings of exclusive palliative care. Besides, most early-onset deaths were directly related to the primary infection through intractable shock and multiple organ failure . In addition, 6.4 % of early decedents were diagnosed with mesenteric ischemia likely to act as a consequence or a contributor of multiple organ failure. Most late deaths were related to ICU-acquired complications such as nosocomial infections and",
"Title: Epidemiology and outcome of severe pneumococcal pneumonia admitted to intensive care unit: a multicenter study\nPassage: a high rate of fatality, with more than one fourth of the patients dying in hospital. The highest proportion of death occurs early in the course of the disease, despite an excellent proportion of initial adequate antibiotherapy . This is considered to be related to the early inflammatory process, which is overwhelming host defences. In a recent study, Garcia-Vidal et al. investigated independent factors associated with early deaths in CAP and demonstrated that age, altered mental status, multilobar pneumonia, shock, bacteraemia and inadequate empiric antibiotic therapy were predictors of death within 48 hours . The small number of patient dying",
"Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: Local elaboration of inflammatory and chemotactic mediators is considered to be a requirement for the development of systemic disease symptoms, with those abnormalities sometimes culminating in shock and death. Yet it is not hypoxemia, due to the prominent pulmonary edema, that leads to death in most fatal cases of HCPS, but rather intoxication of the heart by as-yet-undefined mediators that leads to the low cardiac output state and the associated shock syndrome . It is tempting to speculate that mediators produced in the lung in connection with the inflammatory infiltrate can percolate through the coronary circulation with minimal dilution in",

"Title: Hepatitis C Virus Non-Structural Protein 3 Interacts with Cytosolic 5′(3′)-Deoxyribonucleotidase and Partially Inhibits Its Activity\nPassage: Hepatitis C virus is a major cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma . Infection with HCV is also etiologically involved in the development of B-cell lymphomas . This virus belongs to the genus Hepacivirus in the family Flaviviridae. The HCV genome is a single, positive-stranded RNA with a nucleotide length of about 9.6 kb. It encodes a polyprotein precursor of approximately 3,000 amino acids. This polyprotein precursor is processed by host and viral proteases into at least 10 different proteins, which are arranged in the order of NH2-C-E1-E2-p7-NS2-NS3-NS4A-NS4B-NS5A-NS5B-COOH. C, E1, and E2 are structural proteins while NS2-NS5B",
"Title: Immunization with a Recombinant Vaccinia Virus That Encodes Nonstructural Proteins of the Hepatitis C Virus Suppresses Viral Protein Levels in Mouse Liver\nPassage: in the HCV protein levels was observed in the mice treated with LC16m8, rVV-CN2, or rVV-CN5. These results indicated that HCV nonstructural proteins might be important for effects of therapeutic vaccines. In contrast, rVV-CN5 which encoded HCV structural and non-structural proteins did not show any significant effects. These results indicated that HCV structural proteins might have inhibited the therapeutic effects of the non-structural proteins. Therefore, it may be important to exclude the HCV structural proteins as antigenic proteins when developing therapeutic vaccines against chronic hepatitis C.",

These data lead to the belief that this disease is due to multiple factors that interact with each other.

It has been demonstrated that siRNAs targeting the S, M, or L segment of ANDV could reduce viral replication in Vero E6 cells or human lung microvascular endothelial cells and that an S-targeted siRNA pool seemed to be more efficient in reducing viral transcription and replication than M-or L-targeted siRNA in Vero E6 cells.",

"Title: Chikungunya: A Potentially Emerging Epidemic?\nPassage: The E1-A226V mutation also enabled an increase in infectivity of Ae. albopictus when compared to its infectivity of Ae. aegypti , and with several factors taken together, Ae. albopictus has become the new preferred and more lethal vector for CHIKV . In fact, Tsetsarkin et al. found that a Green Fluorescent Protein tagged E1-A226V virus was 100 times more infective to Ae. albopictus than it was to Ae. aegypti . In all the Indian Ocean Islands, Ae. albopictus became the main vector for CHIKV within 1-2 y after CHIKV was introduced to the region .",
"Title: Dengue Fever, Hawaii, 2001–2002\nPassage: Ae. albopictus was the vector responsible for the 2001 Hawaii outbreak. Both entomologic surveys support that Ae. albopictus is ubiquitous, often common on all the islands, whereas Ae. aegypti is restricted to a few small foci on the relatively sparsely inhabited island of Hawaii.",
"Title: Dengue Fever, Hawaii, 2001–2002\nPassage: where Ae. aegypti is present. Compared with Ae aegypti, Ae. albopictus is considered to be an inefficient epidemic dengue vector because it is less anthropophilic and not as well adapted to urban domestic environments . Ae. albopictus will readily feed on humans, but usually only on a single person, and it also feeds on other animals, which decreases the probability of human contact . Lifestyle factors may also help explain why Hawaii's dengue outbreak was limited . Residences in many affected areas often had dense, uncultivated vegetation near housing and, not infrequently, an abundance of items that could serve as",

RanBP10 is a cytoplasmic guanine nucleotide exchange factor that modulates noncentrosomal microtubules involved in mitosis, while cytochrome P450 catalyses diverse reactions in fungal primary and secondary metabolism, and xenobiotic detoxification. As for PM-milR-M2, 20 potential targets were predicted, which include 13 transposon or transposable elements and seven conserved hypothetical proteins.",
"Title: Perturbations at the ribosomal genes loci are at the centre of cellular dysfunction and human disease\nPassage: In addition to RNA Polymerase I, optimal rRNA gene transcription requires a number of accessory factors that facilitate Pol I recruitment, initiation, promoter escape, elongation, termination and re-initiation . Pol I transcription begins with the formation of the preinitiation complex by the upstream binding factor and the TBP-containing complex selectively factor at the rDNA promoter. SL-1 confers promoter sequence specificity by recognizing the core promoter element and it promotes a stable interaction between UBF and the rDNA promoter . In turn, UBF binds the upstream and core promoter elements as a dimer, possibly looping the intervening DNA into a nucleosome",

"Title: Evolution of Genome Size and Complexity in the Rhabdoviridae\nPassage: Substantial variation in genome size and complexity was also observed in many rhabdovirus genera, suggesting that the length of the genome is not heavily constrained in all members of the family. Indeed, the presence of new ORFs and/or very long stretches of non-coding sequence within or between transcriptional units was noted frequently. Previous observations have demonstrated that foreign genes of up to~6 kb can be inserted into the VSIV genome without significant disruption to viral replication in vitro . Expanded VSIV genomes were morphologically similar but proportionally longer than wild-type viruses, suggesting that the unique morphology of the rhabdovirus particle",
"Title: Evolution of Genome Size and Complexity in the Rhabdoviridae\nPassage: may more readily accommodate genome expansion than other virion structures. A significant body of evidence suggests that genome size in RNA viruses is likely to be constrained by low replication fidelity , and a relationship between genome size and error rate has been observed in a diverse array of organisms . However, if the genome sizes of rhabdoviruses are constrained by selective pressures other than those imposed by the background mutation rate, genome expansion may not require a concomitant reduction in polymerase error rates. As the mutation rate of rhabdoviruses has only been determined experimentally for VSIV thus far ,"

"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: 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 .",

This peptide prevents iron absorption from the small intestine and releases iron from reticuloendothelial cells. In infectious diseases, macrophages and bacteria compete to absorb iron . Macrophages interfere with the absorption of iron by bacteria. Eventually, the pathogen does not grow and replenish. Factors that cause hepcidin production are increased in bone marrow and anemia. Other factors that increase the production of hepcidin are iron accumulation and inflammation .",

In low concentrations of hepcidin, ferritin is present in the cell membrane, allowing the release of iron.

"Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: The shorter nucleocapsid or N protein is a structural component of the viral nucleocapsid, along with the genomic viral RNA segments. As an RNA-binding protein that engages the hairpin termini of the genomic segments with high affinity , it limits the access of the RNA to host nucleases and helps to render viral replication a closed process within the cytoplasm. It also acts as a peripheral membrane protein, as does the L protein , an activity that could play a role in its presumed, but not yet demonstrated function as matrix . Until recently, it had not been appreciated that",

"Title: Resistance to Rhabdoviridae Infection and Subversion of Antiviral Responses\nPassage: mice have two other IFITM genes: IFITM6 and IFITM7. . These proteins inhibit viral membrane fusion, thus resulting in cellular protection from a diverse range of infections. An early observation of IFITM proteins controlling viral infection was reported in 1996 , where overexpression of IFITM1 was shown to inhibit VSV replication, although less potently than the IFN-induced protein MxA . This study is the first description of the antiviral activity of an IFITM protein.",
"Title: Resistance to Rhabdoviridae Infection and Subversion of Antiviral Responses\nPassage: All IFITM proteins have been shown to restrict cell entry of many viruses . However, IFITM3 is the most potent IFITM family member in restricting viral replication in cell culture . IFITM3 inhibits a VSV entry step following endocytosis, but at or before the point of primary transcription of incoming viral genomes . Both the N-terminal 21 amino acid residues and C-terminal transmembrane region of IFITM3 are required for its antiviral function. In addition, IFITM3 has been shown to inhibit an early stage of the RABV replication cycle by targeting entry mediated by the viral glycoprotein .",
"Title: Chemical Synthesis of the Highly Hydrophobic Antiviral Membrane‐Associated Protein IFITM3 and Modified Variants\nPassage: Interferon-induced transmembrane protein 3 is a1 33 amino acid membrane-associated protein that inhibits the replication of pathogenic viruses.This protein was first named fragilis and reported by Saitou and co-workers in 2002, but interest surged when its antiviral properties came to light during the 2009 H1N1 influenza pandemic. Everitt and co-workers reported that patients lacking full IFITM3 were more quickly and severely infected, leading to adramatic increase in mortality.S ubsequent studies have shown that IFITM3 exhibits antiviral activity against al arge number of viruses, including West Nile virus, Dengue virus, Filoviruses , SARS Coronavirus, Rift Va lley fever virus, HIV-1 and,",
"Title: Resistance to Rhabdoviridae Infection and Subversion of Antiviral Responses\nPassage: The IFN-inducible transmembrane genes are enhanced by cell treatment with IFNs since they contain the ISREs in their promoter. IFITM proteins belong to the CD225 protein superfamily, which can be found in nearly every domain of life, ranging from bacteria to invertebrates to primates. In humans, there are at least four functional members of IFITM proteins: IFITM1, IFITM2 and IFITM3, previously named 9-27, 1-8D and 1-8U, respectively, are expressed in a variety of tissues; IFITM5 is limited to the bone. IFIM4P is a pseudogene ). Mouse IFITM1, IFITM2, IFITM3 and IFITM5 genes are orthologues to their human counterparts. In addition,"

Pol I transcribes rDNA to produce the 47S rRNA, which is the precursor of the mature 28S, 5.8S, and 18S rRNAs.

The structure of nucleoli is highly dynamic and is tightly coordinated with cell cycle progression. Nucleoli disassemble at the onset of mitosis coinciding with inactivation of Pol I transcription and reassemble during telophase as rDNA transcription is reinitiated. The rate of rRNA gene transcription reaches a maximum in S-and G2 phases, is halted at the onset of mitosis and slowly reactivated as cell enter G1 .

About 12% of these FECV-positive cats have developed immune-mediated fatal FIP disease . The prevalence of FIP among felines is due to continual cycles of infection and reinfection of FECV and indiscernible clinical symptoms of infected cats with FECV at an early stage before the progressive development of FIPV.",

In other words, the collection of data such as the rate of onset and resolution of an exacerbation from longitudinal studies could be used to determine probabilities of second, third, fourth, etc., exacerbation events in individual patients .

"Title: Markers of exacerbation severity in chronic obstructive pulmonary disease\nPassage: Finally, the compatibility between the studies of COPD exacerbation that we analysed may have been limited by substantial variations in the time and location of studies. Exacerbations are more likely in summer but many studies failed to report the time of year or the time period for study implementation. Thus, seasonal effects, combined with the low incidence of exacerbations per patient, could represent an inherent bias. In addition, different institutions probably had different standards with respect to diagnosis and management of COPD exacerbations when these studies were performed. Such variations may also explain any observed inconsistencies in our findings. However,",

For each study, we noted the type of definition used to define an exacerbation such as symptom-or event-based as well as the research question asked, the experimental design used, any sponsorship, and the presence or absence of data from individual study patients.

"Title: Antibody Engineering for Pursuing a Healthier Future\nPassage: Filamentous bacteriophages used in phage display techniques are viruses that belong to the Inoviridae family. There are fewer of these filamentous phages in this genus compared with tailed phages. Inovirus virions are 7 mm in diameter, contain circular DNA enclosed in a protein capsid, and infect both Gram negative and positive bacteria. They do not lyse host cells, instead, they are packed and extrude at the surface .",
"Title: Architectural Insight into Inovirus-Associated Vectors (IAVs) and Development of IAV-Based Vaccines Inducing Humoral and Cellular Responses: Implications in HIV-1 Vaccines\nPassage: Text: Filamentous bacterial viruses are a group of thread-like viruses containing single-stranded DNA genomes. Collectively, they constitute the genus Inovirus in the family Inoviridae, the terms deriving from the Greek word Ίνα for filament , and they are commonly called filamentous bacteriophages. There are over 50 different known individual species of filamentous viruses; the majority of them capable of infecting Gram-negative bacteria. The complex interaction between filamentous phages and their bacterial hosts is specified by receptor organelles that are usually encoded by transmissible plasmids . One of the most intriguing features of inoviruses is that they are assembled at the",
"Title: Beyond phage display: non-traditional applications of the filamentous bacteriophage as a vaccine carrier, therapeutic biologic, and bioconjugation scaffold\nPassage: Long before the identification of filamentous phage, other types of bacteriophage were already being used for antibacterial therapy in the former Soviet Union and Eastern Europe . The filamentous phage, with its nonlytic life cycle, has less obvious clinical uses, despite the fact that the host specificity of Inovirus and Plectrovirus includes many pathogens of medical importance, including Salmonella, E. coli, Shigella, Pseudomonas, Clostridium, and Mycoplasma species.",
