The effects of a 1.8 GHz continuous electromagnetic fields on mucociliary transport of human nasal mucosa
… electromagnetic fields (EMF) on human nasal mucociliary transport and to determine the pathophysiology of ciliary beat frequency (CBF) during an EMF-induced change. Human nasal mucosa cells were exposed to a 1.8 GHz EMF (SAR= 1.0 W/kg), and CBF was analyzed using an optical flow technique with …

Identification of a ciliary defect associated with pulmonary nontuberculous mycobacterial disease
… because diseases with defects of mucociliary transport have high rates of PNTM disease that increase with age, suggesting a direct connection between airway epithelial function and PNTM disease. I found that PNTM patients have a distinct respiratory epithelial phenotype ex vivo and …

Ultrastructure and function of respiratory cilia in critical illness
… in the intensive care unit (ICU). The mucociliary transport system is the major defence mechanism against such infection and whilst its efficiency has been shown to be decreased in ICU patients there are few reports in the literature describing the ultrastructure of the respiratory …

Effect of Smoke Exposure and Ethanol Ingestion on Anti-Pneumococcal Host Defenses
… the lungs. This EtOH induced defect in host mucociliary defense was dose dependent, and was intensified by concurrent smoke exposure. The increased movement of pneumococci into the lungs of the smoke-exposed and EtOH-fed rats correlated to deficits in the ability of their ciliated tracheal …

Cirrhosis-Induced Defects in Innate Puemonary Defenses Against Streptococcus Pneumoniae
… analyzed within this research included mucociliary clearance, early pre-neutrophil- and later neutrophil-mediated defenses, and in vivo complement deposition inside the lungs. Cirrhosis was induced in male Sprague-Dawley rats by weekly gavage with carbon tetrachloride, whereas control rats …

The Effects of Chronic Ethanol Ingestion and Smoke Exposure on Anti-Pneumococcal Host Defenses
… by EtOH ingestion, but EtOH did not impair ciliary beating. Smoke exposure reduced pneumococcal movement into the lungs regardless of diet, and this was correlated with a significant increase in ciliary beat frequency. The effect of concurrent smoke exposure and EtOH ingestion on …

Understanding the Collective Dynamics of Motile Cilia in Human Airways
Eukaryotic organisms rely on the coordinated beating of motile cilia for a multitude of fundamental reasons. In smaller organisms, such as Paramecium and the single cell alga Chlamydomonas reinhardtii, it is a matter of propulsion, to swim towards a higher concentration of nutrients or away from …

Radiologic, Histologic and Functional Evaluation after Implantation of Cultured Trachea Allograft : in vivo study
BACKGROUND: Commonly known as praying about how hard of a reconstruction, cartilage grafts, anastomosis country EP and the glass plate or Sophie. The sum of the areas of narrowing it after removing the door if possible, all the way to the ideal treatment in patients with anastomosis hard liquor, …
