As he spoke, a little bubble formed from the tears and mucus saturating his upper lip.
The 26-year-old rock 'n' roller suffers from cystic fibrosis, which fills her lungs with bacteria-infested mucus.
Hardest hit are the lungs, which fill with mucus that can cause deadly pneumonia.
White's tree frogs must use all that mucus for something, but not as glue.
An inherited condition, cystic fibrosis affects the cells that produce mucus, sweat and digestive juices.
If they stopped, we'd be flooded with mucus that provides a fertile breeding ground for bacteria.
An asthma attack occurs when the airways narrow too much or produce too much mucus.
They have also been linked to mucus secretion and maybe even the coughing associated with the disease.
Because her donor lungs are free of the CF gene, they do not fill with sticky mucus.
Polyps are abnormal tissue growths of the mucus membrane that are frequently identified as precursors of cancer.
FORBES: Study: Daily Aspirin Cuts Hereditary Cancer Risk in Half
The lining of the airways becomes inflamed and starts to swell and mucus or phlegm can be produced.
"The virus is happy if the mucus droplet completely evaporates and leaves it floating around" in the air.
Next, the researchers compared the viscosity of tree-frog mucus with that of water.
They found that the mucus film was typically less than 35 nanometres thick (a nanometre is a millionth of a millimetre).
When something irritates the airways of a patient with asthma, the airways become tightened, inflamed and produce too much sticky mucus.
They spiked droplets of human mucus with live flu virus, and then exposed it to air with varying levels of moisture.
In addition, the mucus is a perfect breeding ground for bacteria, and patients are vulnerable to illnesses which can cause permanent damage.
For example, the genome shows that El Tor can produce all the enzymes required to live off fucose, a sugar found in intestinal mucus.
When inflammation from allergies or infections swells the lining of the sinuses, the mucus builds up behind the blocked ostia, resulting in pressure and pain.
They figured out the flu kept its virulent characteristics best in human mucus, which Dr. Marr took from the dripping nose of her 1-month-old baby.
When the balloon is inflated, the fragile bones of the passageways are permanently moved aside a millimeter or so to open up air and mucus flow.
The Bull paraded Max around the forest as everyone whooped and danced in a very ugly drool and mucus spraying left and right but celebratory kind of way.
The team says the brush layer protects cells from the sticky mucus and acts as a "second barrier" in case viruses or bacteria penetrate the mucus.
These cause all the features of asthma, including swelling and narrowing of the bronchi and secretion of thick mucus which make it difficult for patients to breathe.
The extent of the delay indicated the viscosity of the fluid, and toe-pad mucus was found to be little more than one-and-a-half times as viscous as water.
Approximately 7, 500 people in the UK have the inherited condition, in which the lungs produce far too much mucus, clogging the airways and making it hard to breathe.
Professor Viney was helped in his work by a sixteen year old high school student, Mairi Struthers of Wishaw, who collected mucus from land snails housed at Edinburgh Zoo.
As a student, at Reed College, Steve Jobs came to believe that if he ate only fruits he would eliminate all mucus and not need to shower anymore.
But in conditions such as cystic fibrosis or chronic obstructive pulmonary disease (COPD), the "brush" fails to work properly, they suggest, becoming squashed and trapping mucus, which then becomes stuck to cells.
It is not known if the Coxsackie B virus grows in the respiratory tract or in the gut -- so no one is sure if it is passed through mucus or feces.
