The muscles that surround some of the airways can be stimulated by this airway irritation. (medicinenet.com)

Impaired lung function is often caused by cigarette smoking, making it challenging to disentangle its role in lung cancer susceptibility. (nature.com)

Lung transplantation-related pathology encompasses a spectrum of disorders that include, but are not limited to, indications for lung transplantation (seen in explanted lungs), surgical complications (airway anastomotic and vascular complications), ischemia-reperfusion injury, rejection (acute and chronic), infections, and posttransplantation lymphoproliferative disorders (PTLDs). (medscape.com)

Of the total 6-min nebulized dose (i.e., drug aerosol dose leaving the nebulizer [not the nebulizer charge]), 1.5% ± 0.7% reached the right lung, with only approximately one third of that (0.6%) penetrating to the peripheral lung zone. (snmjournals.org)
There is considerable room for improvement in aerosol delivery in this age group, with greater emphasis on targeting narrowed peripheral airways with superfine aerosols. (snmjournals.org)

Rhinovirus is emerging as a lead viral pathogen although little is known about the inflammatory response triggered by rhinovirus in the CF lung. (ubc.ca)

Inflammation of the epiglottis is known as epiglottitis. (wikipedia.org)
For this reason, acute epiglottitis is considered a medical emergency, because of the risk of obstruction of the pharynx. (wikipedia.org)

In addition, data from in vitro studies on lung cells were consistent with an anti-inflammatory function of adiponectin [ 11 , 12 ], and adiponectin-deficient mouse models develop lung function impairment and systemic inflammation [ 13 , 14 ]. (hindawi.com)

Integrative analyses reveal that pulmonary function instruments, including 73 novel variants, influence lung tissue gene expression and implicate immune-related pathways in mediating the observed effects on lung carcinogenesis. (nature.com)
And it provides better access to smaller areas of the lung tissue. (rochester.edu)
Normally, alpha-1-antitrypsin is made in the liver and while traveling through the circulation of the lung it inhibits proteases that may cause excessive tissue destruction. (byui.edu)
The ingredients may otherwise cause local tissue necrosis and granuloma in the lungs. (who.int)

OSA is characterized by recurrent episodes of partial or complete obstruction of the upper airway during sleep. (pulmonaryandsleephealth.com)

This is done so oxygen can be sent right into your lungs while the bronchoscope is in place. (rochester.edu)
The lungs and airways become inflamed, causing breathing difficulties and poor oxygen exchange. (vetinfo.com)
These interruptions in breathing can significantly impact lung function and oxygen levels. (pulmonaryandsleephealth.com)
Studies have shown that inadequate sleep can reduce lung capacity, decrease oxygen saturation levels, and compromise the ability of the lungs to clear mucus and other airway irritants. (pulmonaryandsleephealth.com)
This would suggest that if equal volumes of air and blood meet each other in the lungs then we would have a V/Q ratio of 1 for the optimal movement of oxygen to the blood. (byui.edu)

The etiology of lung transplantation-related pathology is almost always immune-mediated. (medscape.com)
This is important because some of the earlier attempts at a SARS vaccine (back in 2002-2004) showed ADE effects (antibody-dependent enhancement with increased immune-mediated inflammation and lung damage following vaccination) in mouse models. (educatetruth.com)

This obstruction can be the result of physical blockages or inflammation of the airway tissues. (circadianbluelight.com)

The first is obstruction of the small airways by fibrosis and mucus. (reliasmedia.com)

Cigarette smoking is by far the most common cause of emphysematous lung damage. (biomedcentral.com)
However, the cellular and molecular mechanisms of the pathophysiology of emphysematous lung damage remain enigmatic. (biomedcentral.com)
It is yet to be known whether p-BSQ of CS causes apoptosis and emphysematous lung damage. (biomedcentral.com)

however, knowledge on the distal lung is limited. (ersjournals.com)
Since then, more sophisticated invasive and noninvasive techniques for measurements of the distal airways have supported the importance of distal airway resistance [ 18 , 19 ]. (ersjournals.com)
The area of the lung that is distal to a terminal bronchiole is termed the acinus. (medscape.com)

These findings support a causal role of pulmonary impairment in lung cancer etiology. (nature.com)

The rhythmic movement of the cilia promotes the flow of the superficial liquid lining of the epithelium, along with mucin and other particulate material (eg, cells and debris) from within the lung to the pharynx. (medscape.com)

In the development and progression of lung cancer, a pathogenic role of adiponectin was defined by both in vivo and in vitro studies [ 15 , 16 ]. (hindawi.com)

BPIFA1 and BPIFB1 are proposed innate immune molecules expressed in the upper airways. (ubc.ca)
In reality, there is a greater movement of air in the upper portions of the lung relative to perfusion. (byui.edu)
An exam of the throat and upper airway will be done. (medlineplus.gov)

Fluid builds up in the airway and mucous membranes may swell, putting the dog at risk for a breathing obstruction. (vetinfo.com)
