The first successful direct transplant of a trachea is a medical milestone that could help thousands of people with airways damaged by ventilators and other causes. Sonia Sein, outside her Bronx ...

The trachea is also lined with tiny hair-like structures called cilia. These help push mucus that contains debris or pathogens out of the trachea. A person then either swallows or spits out the mucus.

Mechanical engineers have developed a system of artificial cilia capable of monitoring mucus ... with an airway stent within an artificial trachea and sheep trachea. Sensing signals are ...

However, any artificial tubing will cause inflammation and further damage to the trachea, and because these tubes don't contain cilia it leads to mucus plugging and the patient can feel like they ...

In the former he found that the bronchial epithelium contained more goblet cells, shorter cilia and a thicker epithelium ... 22 From the trachea and bronchi of human beings (or animals) a cup ...

But if you breathe in harmful things like cigarette smoke, the cilia can stop working. This can lead to health problems like bronchitis. Cells in your trachea and bronchial tubes make mucus that ...

The HEATR2 protein (red) is located in the body of airway cells lining the trachea, not in the cilia (green) or the nuclei (blue). Finding HEATR2 outside of the cilia was the first clue for Amjad ...

But together, these structures routinely pull off biological marvels within the body. Cilia remove inhaled pathogens from the respiratory tract, carry cerebrospinal fluid across brain cavities ...
