Lung adenoma susceptibility protein 2
Lung adenoma susceptibility protein 2 (LAS2, mouse gene 4930503L19Rik, alias Lars) is a mouse lung tumor suppressor on distal chromosome 18, a Pas1 modifier; its human orthologue C18orf54 is deleted in about 40% of lung adenocarcinomas. Not LARS2, ALS2, ALAS2, or SLA2.
Lung biopsy
Lung biopsy is a diagnostic procedure that removes a sample of lung tissue, through the chest wall, a bronchoscope, or surgery, to diagnose lung cancer, interstitial lung disease, or infection.
Lung cancer
Lung cancer: cancer of lung tissues lining air passages; two main types, non-small cell (NSCLC) and small cell (SCLC). Smoking causes about 85% of cases; leading cause of cancer death worldwide, about 2.6 million cases and 1.9 million deaths in 2024.
Lung clearance index
The lung clearance index (LCI) is a pulmonary function test that counts how many breaths it takes to wash an inert tracer gas out of the lungs.
Lung Institute
Lung Institute is the name of two unrelated American organizations: an academic lung center of Baylor College of Medicine in Houston, and a Dallas stem cell clinic chain.
Lung irradiation
Lung irradiation is radiation therapy delivered to lung tissue, mainly as stereotactic body radiation therapy (SBRT) for localized tumors or whole-lung irradiation for diffuse metastases.
Lung resection
Lung resection is the surgical removal of part or all of a lung, from a wedge or segment to a whole lung, most often to treat lung cancer.
Lung transplantation
Lung transplantation replaces one or both diseased lungs with donor lungs for end-stage disease such as COPD, cystic fibrosis, or pulmonary fibrosis; first done 1963, routine since the 1983 Toronto success.
LUNG trial
LUNG trial (Lung UltrasouNd Guided surfactant therapy): international multicenter RCT (NCT05198375) in 668 preterm infants at 25+0 to 29+6 weeks testing lung ultrasound score > 8 versus FiO2 > 0.30 for guiding surfactant, with BPD or death as the primary outcome.
Lung ultrasonography
Lung ultrasonography is a bedside imaging method using ultrasound at the chest wall to diagnose pleural effusion, consolidation, interstitial syndrome, and pneumothorax without ionizing radiation.
Lung ultrasound
Lung ultrasound is a bedside, artifact-based imaging method detecting pleural effusion, consolidation, pneumothorax, and interstitial syndrome; its BLUE protocol diagnoses acute respiratory failure causes with 90.5% accuracy.
Lung ultrasound score
The lung ultrasound score is a bedside score that grades aeration loss across 12 chest regions, summing grades of 0 to 3 into a total of 0 to 36.
Lung Volume Measurements
Lung volume measurements determine absolute lung gas volumes (FRC, RV, TLC) by body plethysmography, multiple breath washout, helium dilution, or imaging, standardized in the 2023 ERS/ATS technical statement updating 2005.
Lung volume reduction surgery
Lung volume reduction surgery (LVRS) is an operation for severe emphysema in which the most damaged 20–35% of each lung is removed to ease breathing.

Lungfish
Lungfish (Dipnoi) are lobe-finned freshwater fish that breathe air using lungs, dating to the Early Devonian about 400 million years ago, with six species in Africa, South America, and Australia.
Lungi
Lungi: a sarong-type lower garment of South Asia, from Hindi/Urdu lungi (Persian origin), worn wrapped or as a sewn tube from waist to ankle across India, Bangladesh, Pakistan, Sri Lanka, and Myanmar (longyi).
Lungo
Lungo (caffè lungo, café allongé): a long espresso, same 7–9 g dose and 9 bar pressure as a standard shot but roughly double the water, yielding 50–60 mL, more bitter, slightly more caffeine; distinct from an Americano.
