Vitamin D may slow the progressive decline in the ability to breathe that can occur in people with asthma as a result of human airway smooth muscle (HASM) proliferation, according to researchers at the University of Pennsylvania. The group found that calcitriol, a form of vitamin D synthesized within the body, reduced growth-factor-induced HASM proliferation in cells isolated from both persons with asthma and from persons without the disease. The proliferation is a part of process called...

There may be a new way to predict mortality in patients with idiopathic pulmonary fibrosis (IPF), a devastating disease that slowly petrifies the lungs. Most patients live only three years after diagnosis on average; however, some remain stable for many years, while for others, the disease progresses more rapidly."There is no effective treatment [for IPF] and many patients, if eligible, are referred for lung transplantation. Identification of surrogate short-term measures of mortality is...

A new research study suggests Vicks VapoRub, the salve used to relieve cough and congestion symptoms, can cause severe breathing problems in children under 2 when inappropriately applied directly under the nose. Using the product in this way can cause a young child's tiny airways to swell and fill with mucus, triggering severe breathing problems, researchers wrote in the journal Chest. "The ingredients in Vicks can be irritants, causing the body to produce more mucus to protect the airway,"...

Hope is on the horizon for premature infants born before their lungs have a chance to fully develop. "Within minutes of birth, a baby relies solely on its lungs to get the oxygen it needs," study author Paul Kemp, from Cardiff University in the U.K., was quoted as saying. But lung development is one of the last things that occurs in the womb, so when babies are born too soon, their lungs don't have the ability to take in enough oxygen to supply the bloodstream. This results in respiratory...

Cincinnati Children's study also shows gene's importance to surfactant productionScientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing.In a study posted online by the Proceedings of the National Academy of Sciences (PNAS), investigators at Cincinnati Children's Hospital Medical Center deleted the Foxm1 gene in embryonic mice.Although lung development in the mice progressed...

By The Associated Press CHICAGO (AP) - Inhaler drugs used by millions of people with emphysema and bronchitis might slightly raise the risk for heart attacks and even death, a study suggests.The results aren't conclusive, and inhalers provide significant relief for these patients struggling to breathe. But the study authors urged doctors to closely monitor patients who use the inhalers.Most affected patients have both emphysema and chronic bronchitis. The condition's formal name, chronic...

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

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...
