Pseudomonas aeruginosa is a major cause of chronic lung infections in cystic fibrosis (CF) patients. The ability of the bacterium to form biofilms and the presence of a thick and stagnant mucus in the airways of CF patients largely contribute to antibiotic therapy failure and demand for new antimicrobial agents able to act in the CF environment. The present study investigated the anti-P. aeruginosa activity of lin-SB056-1, a recently described semi-synthetic antimicrobial peptide, used alone and in combination with the cation chelator ethylenediaminetetraacetic acid (EDTA)...

Pseudomonas aeruginosa (P. aeruginosa) is a gram-negative bacterium that causes a variety of diseases in compromised hosts. Bacterial endotoxins such as lipopolysaccharide (LPS) are the major outer surface membrane components that are present in almost all gram-negative bacteria and act as extremely strong stimulators of innate immunity and inflammation of the airway. This study was undertaken to determine the effect of combined administration of Gentamicin (GENT) as an antibiotic and Dexamethasone (DEXA) as an anti-inflammatory drug on some immunological and histological parameters...

World Trade Center-particulate matter(WTC-PM) exposure and metabolic-risk are associated with WTC-Lung Injury(WTC-LI). The receptor for advanced glycation end-products (RAGE) is most highly expressed in the lung, mediates metabolic risk, and single-nucleotide polymorphisms at the AGER-locus predict forced expiratory volume(FEV). Our objectives were to test the hypotheses that RAGE is a biomarker of WTC-LI in the FDNY-cohort and that loss of RAGE in a murine model would protect against acute PM-induced lung disease...

BACKGROUND: Immunosuppression therapy after lung transplantation fails to prevent bronchiolitis obliterans syndrome (BOS) in many patients, primarily a disease of the small airways. We have reported that BOS is associated with a lack of suppression of cytotoxic mediators, and proinflammatory cytokines, in peripheral blood T, NKT-like (particularly CD8+) and NK cells. We also showed a loss of glucocorticoid receptor (GCR) in proinflammatory lymphocytes after transplant. It is unknown whether these proinflammatory lymphocytes target the small and/or large airways in BOS...

The ingestion of one's own feces is referred to as coprophagia. In this report, the author discusses a case of coprophagia-associated death in a 36-year-old woman. The woman had a history of intellectual disability, bipolar disorder, and schizoaffective disorder and was living in a group home. At autopsy, examination of the upper airway revealed 4 distinct spherical boli of impacted fecal matter in the oral cavity and pharynx. Death was attributed to asphyxia due to aspiration of stool bolus during an episode of coprophagia...

Nucleolin (NCL) has been reported as a cellular receptor for the human respiratory syncytial virus (RSV). We studied the effects of re-purposing AS1411, an anti-cancer compound that binds cell surface NCL, as a possible novel strategy for RSV therapy in vitro and in vivo. AS1411 was administered to RSV-infected cultures of non-polarized (HEp-2) and polarized (MDCK) epithelial cells and to virus-infected mice and cotton rats. Results of in vitro experiments showed that AS1411, used in micromolar concentrations, was associated with decreases in the number of virus-positive cells...

BACKGROUND: Local delivery of drugs to the lungs of newborn infant represents an unmet need as no drugs have been approved. Potential benefits could be large. Development of aerosol for delivery of drugs to infants and newborn offers huge potential for better therapy. Newborn infants present unique challenges with regard to aerosol therapy. Efficient deposition of aerosolized medications on the neonate airway surface is hampered by anatomical features such as small airway geometries and physiological features such as exquisitely small tidal volumes, rapid breathing and unfavorable inhalation:exhalation ratios...

Respiratory parameters such as flow or rate have complex effects onto exhalation of volatile substances and can hamper clinical interpretation of breath biomarkers. We investigated effects of progressively applied upper-airway resistances onto exhalation of volatile organic compounds (VOCs) in healthy humans. We performed real-time mass-spectrometric determination of breath volatiles in 50 subjects with parallel non-invasive hemodynamic monitoring, breath-resolved spirometry and capnometry during controlled tidal breathing (12 breaths/min)...

A premature male infant was born at 30 weeks' gestation with a birth weight of 1,700 g in a rural hospital. He was diagnosed with respiratory distress syndrome and received continuous positive airway pressure treatment for 26 days. At 26 days after birth, the patient was transferred to our hospital for further evaluation and management. A comprehensive eye examination revealed a stage 3 retinopathy of prematurity (ROP) involving zone 2 in both eyes. The patient was recommended to a provincial-level eye hospital for emergency laser therapy...

Activated CD4 T cells connect to airway smooth muscle cells (ASMCs) in vitro via lymphocyte-derived membrane conduits (LMCs) structurally similar to membrane nanotubes with unknown intercellular signals triggering their formation. We examined the structure and function of CD4 T cell-derived LMCs, and we established a role for ASMC-derived basic fibroblast growth factor 2 (FGF2b) and FGF receptor (FGFR)1 in LMC formation. Blocking FGF2b's synthesis and FGFR1 function reduced LMC formation. Mitochondrial flux from ASMCs to T cells was partially FGF2b and FGFR1 dependent...

Middle East respiratory syndrome coronavirus (MERS-CoV) targets the epithelial cells of the respiratory tract both in humans and in its natural host, the dromedary camel. Virion attachment to host cells is mediated by 20-nm-long homotrimers of spike envelope protein S. The N-terminal subunit of each S protomer, called S1, folds into four distinct domains designated S1(A) through S1(D) Binding of MERS-CoV to the cell surface entry receptor dipeptidyl peptidase 4 (DPP4) occurs via S1(B) We now demonstrate that in addition to DPP4, MERS-CoV binds to sialic acid (Sia)...

MicroRNAs (miRNAs) have been known to affect various biological processes by repressing expression of specific genes. Here we describe an essential function of the miR-34/449 family during differentiation of epithelial cells. We found that miR-34/449 suppresses the cell-cycle machinery in vivo and promotes cell-cycle exit, thereby allowing epithelial cell differentiation. Constitutive ablation of all six members of this miRNA family causes derepression of multiple cell cycle-promoting proteins, thereby preventing epithelial cells from exiting the cell cycle and entering a quiescent state...

Bacterial persisters are a quasi-dormant sub-population of cells that are tolerant to antibiotic treatment. The combination of the aminoglycoside tobramycin with fumarate as an antibacterial potentiator utilizes an anti-persister strategy that is aimed at reducing recurrent Pseudomonas aeruginosa infections by enhancing the killing of P. aeruginosa persisters. Stationary phase cultures of P. aeruginosa were used to generate persister cells. A range of tobramycin concentrations was tested with a range of metabolite concentrations to determine the potentiation effect of the metabolite under a variety of conditions, including a range of pH values and in the presence of azithromycin or cystic fibrosis (CF) patient sputum...

BACKGROUND: Obstructive sleep apnea (OSA) is an increasingly prevalent clinical problem with significant effects on quality of life and cardiovascular risk. Surgical therapy represents an important treatment for those unable to use positive airway pressure. This systematic review examines the available cardiovascular risk reduction data for surgical treatment of OSA. METHODS: A comprehensive literature search was performed. Articles were included if they met the following criteria: (1) adults >18 years (2) OSA diagnosed by sleep study; (3) surgical intervention performed for OSA; (4) one or more physical or biochemical cardiovascular and/or cerebrovascular variables was measured pre-operatively and at ≥14 days postoperatively...

In the immature lung, inflammation and injury disrupt epithelial-mesenchymal interactions required for normal development. Innate immune signaling and NF-κB activation disrupt the normal expression of multiple mesenchymal genes playing key roles in airway branching and alveolar formation. To test the role of the NF-κB pathway specifically in lung mesenchyme, we utilized the mesenchymal Twist2-Cre to drive expression of a constitutively active IKKβ mutant (IKKβca) in developing mice. Embryonic Twist2-IKKβca mice were generated in expected numbers and appeared grossly normal...

OBJECTIVE: The majority of adults sleep with a partner, making sleep a dyadic experience. However, interventions to improve sleep have primarily focused on individuals. This qualitative analysis used a dyadic approach to identify facilitators and barriers to successful treatment of one of the most common sleep disorders, obstructive sleep apnea, with continuous positive airway pressure (CPAP). METHODS: Twenty joint qualitative interviews were conducted with couples, one couple at a time, with a sample of 20 patients with obstructive sleep apnea and their partners to develop an understanding of couples' experiences with CPAP use...
