What was investigated in this study?
[ "Title: Analysis of spatial mobility in subjects from a Dengue endemic urban locality in Morelos State, Mexico\nPassage: Fifty randomly selected cases were asked to participate in the study from which 42 accepted participation. All approached controls agreed to participate. In total 126 individuals were recruited. Our drop-out rate was lower than 1% since one participant did not finish the follow-up due to the loss of the assigned GPS logger. Table 1 describes the main characteristics of the subjects in each group. No statistically significant differences were observed in most of variables except in age, since cases were significantly younger than the intradomestic or population controls .", "Title: Surveillance Study of Influenza Occurrence and Immunity in a Wisconsin Cohort During the 2009 Pandemic\nPassage: We originally hoped to study T-cell cross-protection that might reduce symptom severity, but we also measured a variety of other parameters of pre-existing immunity . For statistical comparison of so many variables, we performed exploratory principal component and discriminant analyses. These analyses did not reveal any significant relationships of antibody or T-cell parameters at baseline with occurrence of pH1N1 infection or with symptom severity.", "Title: The Trojan Chicken Study, Minnesota\nPassage: This study was reviewed and approved by the University of Iowa's Institutional Review Board and Animal Use and Care Committee. The investigators participated in online human and animal subjects training. Informed consent was sought from participants before they were enrolled.", "Title: Examining the knowledge, attitudes and practices of domestic and international university students towards seasonal and pandemic influenza\nPassage: Students attending the main campus of the university were approached to participate in the study. Two methods were used to identify potential participants. Firstly, the interviewer directly approached a convenience sample of students who were located in the food halls and recreation areas of the university campus and invited them to participate. In the latter half of the study, a snowball approach was used. The snowball approach was adopted due to problems with identifying and recruiting postgraduate students. They constitute a considerably smaller percentage of the total student body, often are enrolled externally and attend classes in the late afternoon/evening." ]

MERS-CoV titre decreased somewhat when recovered from milk at 22°C but pasteurization completely ablated MERS-CoV infectivity .

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.

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.

At least three locations have been mooted. First, the historian John Barry has suggested that Loring Miner, a physician in rural Kansas, in the USA, encountered cases in the early weeks of 1918 which, while akin to influenza, posed an unusual risk to life . Miner based his diagnosis on the symptomatology involved, and, interestingly, those symptoms did not include heliotrope cyanosis, which, as time drew on, came to be regarded as the tell-tale most", "Title: The origins of the great pandemic\nPassage: Kansas cases no doubt make for a compelling story, but one that has perhaps left a stronger-than-deserved impression that they were the very first cases.

An elevated amount of extravascular lung water as well as an increased vascular permeability were also observed. This result is confirmed by the chest CT scan findings, showing a large amount of water in the alveoli, in the perivascular and in the pleural space. The pleural effusion was exudative and contained a high quantity of protein which can be explained by a protein leakage rather than by an inflammatory origin.", "Title: Capillary leak-syndrome triggered by Maripa virus in French Guiana: case report and implication for pathogenesis\nPassage: Under normal conditions, the endothelium plays the role of a selective permeable barrier to regulate plasma fluid exchange, as well as molecules and cells trafficking. Disruption of cell junctions, with combination of cell retraction process, lead to the loss of the vascular endothelium barrier function. In such conditions, fluids and proteins infusion are ineffective because of the immediate leakage to the interstitial space with a worsening of the respiratory failure without any efficacy on the hemodynamic state.

Furthermore, the inflammatory environment may also disperse upper airway commensals into the lower airway, further causing inflammation and alteration of", "Title: Key mechanisms governing resolution of lung inflammation\nPassage: Affecting approximately 10 % of UK adults, asthma is a common disorder of multi-factorial origins, with research indicating that both genetics and the environment have a significant role to play. In predisposed individuals, 'normal' environmental antigens transmigrate through the airway epithelia and are presented to naïve T cells, which trigger activation of IgE production by B cells. IgE interacts with receptors on the surface of tissue resident mast cells, and further exposure to the antigen results in IgE cross-linkage with cell activation. The resultant mast cell degranulation causes release of mediators including histamine, LTB 4 , IL-8 and IL-10 and", "Title: Respiratory Viral Infections in Exacerbation of Chronic Airway Inflammatory Diseases: Novel Mechanisms and Insights From the Upper Airway Epithelium\nPassage: of the classical symptoms of chronic airway inflammatory diseases . In addition, the expression of vasodilating factors and fluid homeostatic factors such as angiopoietin-like 4 and bactericidal/permeabilityincreasing fold-containing family member A1 are also associated with viral infections and pneumonia development, which may worsen inflammation in the lower airway Akram et al., 2018) .

During the replication process, the cells release antiviral factors and cytokines that alter local airway inflammation and airway niche . In a healthy airway, the inflammation normally leads to type 1 inflammatory responses consisting of activation of an antiviral state and infiltration of antiviral effector cells. This eventually results in the resolution of the inflammatory response and clearance of the viral infection .

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 .

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.

We examined the involvement of MKP-1 in BCG-induced MAPK activation and its consequent cytokine expression. Here, we present evidences that MKP-1 plays an unexpected role in the regulation" ]
