Study affirms self-reported sleep duration as a useful health measure in children

While sleep questionnaires are commonly completed by children and their parents, there has been a lack of data comparing the validity of these self-reported sleep parameters. A new study indicates that these sleep characteristics are relatively accurate compared to one another, and they vary…

Obstructive sleep apnea linked to inflammation, organ dysfunction

Voyagers no longer embark in search of the storied Fountain of Youth, but the quest for longevity is still very much alive for researchers. Chronological age — the passing of time one spends on this planet — cannot be reversed, of course. However, biological…

When mucus can be key to treating colon and airway diseases

Researchers have identified proteins that control mucous production and suggest clues to treating colon and airway diseases.

Researchers breathe new life into COPD research using mouse models

Researchers revealed that the immune cells basophils caused emphysema in mice with COPD-like features induced by intranasal administration of elastase. They showed that basophils, previously linked mainly to allergies and fighting parasites, initiated a cascade of reactions eventually leading to the release of excess…

Sleep apnea creates gaps in life memories

Obstructive sleep apnea (OSA) is estimated to affect over 936 million people worldwide, and people with OSA are known to suffer memory problems and depression. New research builds on the known links between depression and memory, finding that people with untreated OSA have problems…

Poor sleep and heart-related death

Elderly men who experience extended episodes of interrupted breathing while asleep have a high risk of heart problems. Research shows for the first time that poor blood oxygenation is a good indicator of the chance of heart-related death, which cannot be attributed to sleep…

Activated PMN exosomes are pathogenic entities that cause destruction in the COPD lung

Researchers have found a novel, pathogenic entity that is a fundamental link between chronic inflammation and tissue destruction in lungs of patients with COPD. These exosomes from activated neutrophils caused COPD damage when they were instilled into the lungs of healthy mice. Remarkably, neutrophil…

Experimental findings support a connection between mucins in the lung and pulmonary fibrosis

A team of investigators has identified a connection between mucus in the small airways and pulmonary fibrosis.

Can scientists change mucus to make it easier to clear, limiting harm to lungs?

For people with conditions such as cystic fibrosis and COPD, mucus can get too thick and sticky; coughing alone can’t clear it. Infections develop, leading to severe chronic disease and early death. Now, for the first time, scientists have shown why coughing often cannot…

Mucus, cough and chronic lung disease

As a cold ends, a severe mucus cough starts. Sound familiar? Two studies now give explanations: First, crucial mechanisms of the mucus in both diseased and healthy airways; second, what happens in such chronic lung diseases as cystic fibrosis and chronic obstructive pulmonary disease…
