Chapter Eight Molecular Basis of Coronavirus Virulence and Vaccine Development
Publication date: 2016 Source:Advances in Virus Research, Volume 96 Author(s): L. Enjuanes, S. Zuñiga, C. Castaño-Rodriguez, J. Gutierrez-Alvarez, J. Canton, I. Sola Virus vaccines have to be immunogenic, sufficiently stable, safe, and suitable to induce long-lasting immunity. To meet these requirements, vaccine studies need to provide a comprehensive understanding of (i) the protective roles of antiviral B and T-cell-mediated immune responses, (ii) the complexity and plasticity of major viral antigens, and (iii) virus molecular biology and pathogenesis. There are many types of vaccines including subunit vaccines, whole...

Chapter Seven Interaction of SARS and MERS Coronaviruses with the Antiviral Interferon Response
Publication date: 2016 Source:Advances in Virus Research, Volume 96 Author(s): E. Kindler, V. Thiel, F. Weber Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) are the most severe coronavirus (CoV)-associated diseases in humans. The causative agents, SARS-CoV and MERS-CoV, are of zoonotic origin but may be transmitted to humans, causing severe and often fatal respiratory disease in their new host. The two coronaviruses are thought to encode an unusually large number of factors that allow them to thrive and replicate in the presence of efficient host defense mechanisms, especially the ant...

Chapter Two Coronavirus Spike Protein and Tropism Changes
Publication date: 2016 Source:Advances in Virus Research, Volume 96 Author(s): R.J.G. Hulswit, C.A.M. de Haan, B.-J. Bosch Coronaviruses (CoVs) have a remarkable potential to change tropism. This is particularly illustrated over the last 15 years by the emergence of two zoonotic CoVs, the severe acute respiratory syndrome (SARS)- and Middle East respiratory syndrome (MERS)-CoV. Due to their inherent genetic variability, it is inevitable that new cross-species transmission events of these enveloped, positive-stranded RNA viruses will occur. Research into these medical and veterinary important pathogens—sparked by the SAR...

Mpn491, a secreted nuclease of Mycoplasma pneumoniae, plays a critical role in evading killing by neutrophil extracellular traps
In this study, we investigated whether M. pneumoniae possesses resistance mechanisms against the NETs‐mediated killing of neutrophils and found that the bacterium degrades the NETs induced upon M. pneumoniae infection. The NETs‐degrading ability of M. pneumoniae required the production of a secreted nuclease, Mpn491, capable of using Mg2+ as a cofactor for its hydrolytic activity. Moreover, the inactivation of the nuclease resulted in increased susceptibility of M. pneumoniae to the NETs‐mediated killing of neutrophils. The results suggest that M. pneumoniae employs Mpn491 as a means for evading the killing mechanism...

Toxicants in folk remedies: implications of elevated blood lead in an American-born infant due to imported diaper powder
We present interdisciplinary findings from and policy implications of a case of elevated blood lead (13 –18 mcg/dL, reference level<5 mcg/dL) in a 9-month-old infant, linked to a non-commercial Malaysian folk diaper powder. Analyses showed the powder contains 62 % lead by weight (primarily lead oxide) and elevated antimony [1000 parts per million (ppm)], arsenic (55 ppm), bismuth (110 ppm), and thallium (31 ppm). These metal s are highly bioaccessible in simulated gastric fluids, but only slightly bioaccessible in simulated lung fluids and simulated urine, suggesting that the primary lead exposure routes were i...

Congenital cystic adenomatoid malformation associated with esophageal duplication cyst
Congenital cystic adenomatoid malformation (CCAM) of the lung is rare and is characterized by an excessive overgrowth of the terminal bronchioles.1 Patients with CCAM may present either in the newborn period with progressive respiratory distress, or rarely in older children and adults with recurrent pulmonary infections. Intrathoracic foregut duplication cysts are also rare, and depending on their size, may be asymptomatic and discovered incidentally, or may present with a variety of symptoms, most commonly airway or esophageal obstruction.2 The coexistence of both CCAM and esophageal duplication cyst (EDC) is extremely ra...

Growth restriction induced by chronic prenatal hypoxia affects breathing rhythm and its pontine catecholaminergic modulation
Impaired transplacental supply of oxygen leads to intrauterine growth restriction, one of the most important causes of perinatal mortality and respiratory morbidity. Breathing rhythm depends on the central respiratory network modulated by catecholamines. We investigated the impact of growth restriction, using prenatal hypoxia, on respiratory frequency, on central respiratory-like rhythm, and on its catecholaminergic modulation after birth. At birth, respiratory frequency was increased and confirmed in en bloc medullary preparations, where the frequency of the fourth cervical (C4) ventral root discharge was increased, and i...

Interferon beta-1a long-term therapy related to pulmonary arterial hypertension in multiple sclerosis patients
We report two patients with relapsing remitting multiple sclerosis (RRMS) on interferon (IFN) beta-1a treatment for more than 7 years who developed pulmonary arterial hypertension (PAH). Patient 1 developed severe PAH requiring lung transplantation. Histology showed typical proliferative lesions including plexiform lesions consistent with PAH. Patient 2 ceased IFN beta-1a, and their symptoms stabilised. Both cases highlight IFN beta-1a treatment as a potential risk factor for PAH. PAH needs to be considered as a diagnosis in patients on long-term IFN beta-1a treatment who develop new-onset respiratory symptoms. (Source: Multiple Sclerosis)

A Distress Protocol for Respiratory Emergencies in Terminally Ill Patients With Lung Cancer or Chronic Obstructive Pulmonary Disease
A combination of opioid, midazolam, and scopolamine (that we call "distress protocol" [DP]) is used to induce transient sedation when emergencies occur in palliative care. We wished to describe the prescription and administration of DP in terminally ill patients with either lung cancer or chronic obstructive pulmonary disease (COPD). In a retrospective study, 96 of 100 patients with cancer and 85 of 100 patients with COPD had a DP prescribed. Thirty patients with cancer and 29 with COPD received at least 1 DP. All patients receiving a DP for an appropriate indication were sedated within 30 minutes. There was no difference ...

Roles of subunit NuoL in the proton pumping coupling mechanism of NADH:ubiquinone oxidoreductase (complex I) from Escherichia coli
Respiratory complex I has an L-shaped structure formed by the hydrophilic arm responsible for electron transfer and the membrane arm that contains protons pumping machinery. Here, to gain mechanistic insights into the role of subunit NuoL, we investigated the effects of Mg2+, Zn2+ and the Na+/H+ antiporter inhibitor 5-(N-ethyl-N-isopropyl)-amiloride (EIPA) on proton pumping activities of various isolated NuoL mutant complex I after reconstitution into Escherichia coli double knockout (DKO) membrane vesicles lacking complex I and the NADH dehydrogenase type 2. We found that Mg2+ was critical for proton pumping activity of c...

Hypophosphatemia promotes lower rates of muscle ATP synthesis [Research]
Hypophosphatemia can lead to muscle weakness and respiratory and heart failure, but the mechanism is unknown. To address this question, we noninvasively assessed rates of muscle ATP synthesis in hypophosphatemic mice by using in vivo saturation transfer [31P]-magnetic resonance spectroscopy. By using this approach, we found that basal and insulin-stimulated rates of muscle ATP synthetic flux (VATP) and plasma inorganic phosphate (Pi) were reduced by 50% in mice with diet-induced hypophosphatemia as well as in sodium-dependent Pi transporter solute carrier family 34, member 1 (NaPi2a)-knockout (NaPi2a–/–) mice c...

Quick and cheap MIRU-VNTR typing of Mycobacterium tuberculosis species complex using duplex PCR
While minisatellites are usually typed using capillary sequencers or qiaplex systems in developed countries, many low-resource regions cannot afford it. We propose an optimized agarose gel electrophoresis method to genotype Mycobacterium tuberculosis species complex minisatellites in their standardized format (24 MIRU-VNTR). It is based on duplex PCRs combining VNTR loci harboring distinct amplicon sizes whatever the repetition number of each locus. This method performs well both on DNA extracts of good quality and on thermolysates while reducing both workload and reagents costs. (Source: Tuberculosis)

Clinical, Immunological, and Molecular Findings of Patients with p47 phox Defect Chronic Granulomatous Disease (CGD) in Indian Families
AbstractChronic granulomatous disease (CGD) is a group of inherited disorder of phagocytes, resulting from mutations in the components of the NADPH oxidase complex. Reduced or absent oxygen radical synthesis seen in these patients leads to impaired killing of intracellular bacteria and fungi. CGD clinically presents with recurrent and life-threatening infections as well as granulomatous inflammatory responses. p47phox encoded by theNCF1 gene is the most common autosomal recessive form of CGD which is often clinically milder. Here, we are presenting the data on clinical and immunological findings in 21 Indian patients with ...

The effect of smoking status on burn inhalation injury mortality
Conclusion In the sub group of burn patients with inhalation injury, the odds of mortality significantly decreased in pre-existing smokers after adjusting for significant covariates. We postulate that an immune tolerance mechanism that modulates and diminishes the pro-inflammatory response confers a survival advantage in smokers after exposure to acute smoke inhalation injury. Future prospective studies in human and/or animal models are needed to confirm these findings. (Source: Burns)
