Mucociliary clearance has a major role in pulmonary hygiene. MCC effectiveness relies on the correct properties of the airway surface liquid produced, both of the periciliary sol layer and the overlying mucus gel layer, and of the number and quality of the cilia present in the lining of the airways. [3] An important factor is the rate of mucin ...
Dr Terrence Tumpey examines a reconstructed version of the Spanish flu virus at the CDC. An effort to recreate the Spanish flu strain (a strain of influenza A subtype H1N1) was a collaboration among the Armed Forces Institute of Pathology, the USDA ARS Southeast Poultry Research Laboratory, and Mount Sinai School of Medicine in New York
Many theories about the origins and progress of the Spanish flu persisted in the literature, but it was not until 2005, when various samples of lung tissue were recovered from American World War I soldiers and from an Inupiat woman buried in permafrost in a mass grave in Brevig Mission, Alaska, that significant genetic research was made possible.
Mucokinetics: increase mucociliary transport (clearance) and transportability of mucus by cough [2] Mucoregulators: suppress underlying mechanisms of mucus hypersecretion [2] Alternatively, attacking the affinity between secretions and the biological surfaces is another avenue, which is used by abhesives and surfactants.

Mucociliary action carries it down from the nasal passages and up from the rest of the tract to the pharynx, with most of it being swallowed subconsciously. Sometimes in times of respiratory illness or inflammation, mucus can become thickened with cell debris, bacteria, and inflammatory cells.
An unusual surge in flu viruses detected at wastewater treatment plants in California and other parts of the country is raising concerns among some experts that H5N1 bird flu may be spreading ...
James Niven (12 August 1851 – 30 September 1925) was a Scottish physician, perhaps best known for his work during the Spanish Flu outbreak in 1918 as Manchester's Medical Officer of Health. He held that position for 28 years (1894–1922), until he retired. He had previously been Oldham's Medical Officer of Health.
This is a timeline of influenza, briefly describing major events such as outbreaks, epidemics, pandemics, discoveries and developments of vaccines.In addition to specific year/period-related events, there is the seasonal flu that kills between 250,000 and 500,000 people every year and has claimed between 340 million and 1 billion human lives throughout history.
