The ATS and the European Respiratory Society have issued official standards for the quantitative assessment of lung structure. "This is the first concise state-of-the-art review of stereological methods for lung morphometry that formulates practical guidelines for the use of advanced imaging techniques," said ATS past president, John Heffner, M.D. "The proposed standards ensure that the three dimensional window into the lung offered by advanced imaging techniques will provide the sharp and...

A McMaster University researcher has found the first evidence that prolonged exposure to higher levels of the pollutants found in car exhaust fumes and industrial air pollution can lead to hospitalization for pneumonia in adults aged 65 and older. Infectious disease specialist Mark Loeb led a research team to assess the effect of long-term exposure to nitrogen dioxide and sulfur dioxide, both found in motor vehicle emissions, and fine particulate matter, found in industrial air pollution, on...

The persistence of inflammation in the lungs of smokers and even ex-smokers creates an environment that encourages emphysema, a disease that makes breathing more and more difficult. Why some people have this problem and others do not remained a mystery until a consortium of researchers led by Baylor College of Medicine found that the answer lies with certain dendritic cells in the lung. Dendritic cells are antigen-presenting cells, meaning they show proteins to the immune system to provoke a...

Scientists have revealed how environmental irritants such as air pollution and cigarette smoke cause people to cough, in research published today in the American Journal of Respiratory and Critical Care Medicine. The authors of the study, from Imperial College London and the University of Hull, have identified the reaction inside the lungs that can trigger coughing when a person is exposed to particular irritants in the air. They suggest that their findings may ultimately lead to the...

Inflammation still ravages the lungs of some smokers years after they quit the habit. What sparks that smoldering destruction remained a mystery until a consortium of researchers led by Baylor College of Medicine found that certain dendritic cells in the lung "“ the cells that "present" a foreign antigen or protein to the immune system "“ provoke production of destructive T-cells that attack a key protein called elastin, leading to death of lung tissue and emphysema. A report of...

Carbon nanotubes are being considered for use in everything from sports equipment to medical applications, but a great deal remains unknown about whether these materials cause respiratory or other health problems. Now a collaborative study from North Carolina State University, The Hamner Institutes for Health Sciences, and the National Institute of Environmental Health Sciences shows that inhaling these nanotubes can affect the outer lining of the lung, though the effects of long-term...

Scientists have identified the main genetic switch that causes excessive mucus in the lungs, a discovery that one day could ease suffering for people with chronic lung diseases like asthma and cystic fibrosis, or just those fighting the common cold. The discovery was reported in a study posted online Sept. 14 by the Journal of Clinical Investigation. The new research sheds light on what has been a medical mystery - the precise biological reasons that the lungs in people with asthma, cystic...

Cystic Fibrosis
2013-07-19 15:03:45

Cystic fibrosis, also called mucoviscidosis, is an autosomal recessive genetic disorder of the viscous secretions in the body. In turn, it effects the lungs, pancreas, liver, and intestines, as well as all other exocrine glands in the body. The most common genetic mutation that causes CF is a deletion of three nucleotides that results in a loss of phenylalanine, an amino acid at the 508th position on the protein. It should be noted, however, that there are over a thousand other mutations that...

Pharynx

The pharynx is situated directly after the mouth and nose and lies right before the esophagus. Formation and Orientation The pharynx is divided into three separate sections. The nasopharynx is the first part of the pharynx that lies between the soft palate and the base of the skull. The pharyngeal tonsils are located on the back wall of the nasopharynx. This portion of the pharynx is connected to the middle easr by the Eustachian tubes. The nasopharynx is linked to the nasal cavities...

Trachea
2013-01-18 11:28:50

The trachea, commonly called the windpipe, is the air passage-way from the mouth to the lungs. Non-fish vertebrae all have a trachea. The moist with mucus walls of the tube-like structure trap inhaled particles to keep them from entering the lungs. Structure The trachea is an open-ended cylindrical structure that starts at the larynx and ends at the bifurcation. It is about one inch in diameter and can run four to six inches in length. Within the pipe there are anywhere from 15 to 20...

Lung
2013-01-01 15:53:59

The lung is a vital organ that is a part of the respiratory system. Generally a person has two lungs; however, the body can function with only one. The lung’s main function is to move oxygen and carbon dioxide into and out of the bloodstream through gas exchange. The lungs are located lateral to the heart in the thoracic cavity. Each lung has a tip called the apex, which is superior in the body. The bases of the lungs rest on the diaphragm. They appear to be spongy due to their bundles of...
