Prediction of pediatric endotracheal tube size by ultrasonography.
Measuring subglottic airway diameter with ultrasonography facilitates the selection of appropriately sized ETTs in pediatric patients. This selection method better predicted optimal outer ETT diameter than standard age- and height-based formulas....
Tracheo-oesophageal fistula (TOF) and oesophageal atresia (OA).
Inflammatory responses may be induced by a single intratracheal instillation of iron nanoparticles in mice
Magnetite iron nanoparticles have been widely used as contrast agents and in thermal therapy for cancer. However, their adverse effects on human health have not been fully investigated. In this study, iron oxide nanoparticles were prepared using inorganic iron chloride (size: 5.3+/-3.6 nm in phospha...
Complications following tracheoesophageal puncture: a tertiary hospital experience.
Our patients were predominantly males (95.4%) of Chinese descent with a mean age of 62.1 years. The types of voice prostheses used were ProvoxTM (n = 15), Voicemasters (n = 6), and Blom-Singer (n = 1). Prosthesis- related complications occurred in 77.3%. Notable complications were leakage (82.5%), p...
Experimental infection of Muscovy ducks with highly pathogenic avian influenza virus (H5N1) belonging to clade 2.2.
Our team recently demonstrated a good cross-reactivity with hemagglutinin from clade 2.2 and inferred that this could be a good vaccine candidate for ducks. Two challenges using two French H5N1 HP strains, 1) A/mute swan/France/06299/06 (Swan/06299), clade 2.2.1, and 2) A/mute swan/France/070203/07...
The phosphorylation status of membrane-bound nucleoside diphosphate kinase in epithelia and the role of AMP
We show in human, mouse and sheep airway membranes, that the phosphorylation state of membrane-bound NDPK on histidine and serine residues differs dependent on many regulatory factors. GTP (but not ATP) promotes serine phosphorylation (pSer) of NDPK. Further we find that rising [AMP] promotes pSer (...
Strain-specific virulence of Bordetella hinzii in poultry.
These results demonstrate that some strains of B. hinzii are virulent in turkey poults and may asymptomatically colonize chicks, and suggest this agent may be of concern to poultry producers....
Toxicity of monazite particulates and its attenuation with a complex of bio-protectors.
Workers employed on mining, processing and storage of monazite are at risk of exposure to dust with expected adverse health effects. To study the adverse health effects of monazite particles in experiments on rats and to test the possibility of attenuating these effec...
Medullary raphe midline is involved in production of expulsive expirations in anesthetized rabbits.
We conclude that in rabbits, the medullary raphe nuclei participate in the control of expiratory expulsions originating from the trachea....
Development and immunogenicity of recombinant Mycoplasma gallisepticum vaccine strain ts-11 expressing chicken IFN-@c
We have developed ts-11 as a vector to express and secrete chicken IFN-gamma (ts-11 C3) using a transposon-based delivery vector. Following administration of ts-11 C3 in chickens by eye drop, up to 2 weeks post-vaccination, neither significant systemic IFN-gamma expression nor an antibody response a...
