New research in The FASEB Journal suggests that cigarette smoke interferes with the Cystic Fibrosis Transmembrane Conductance Regulator protein, leading to dry, sticky mucus and increased infections If you smoke cigarettes, you have more in common with someone who has cystic fibrosis than you think. A new research report appearing online in the FASEB Journal (http://www.fasebj.org) shows that smoking cigarettes affects the lungs in a way that is very similar to cystic fibrosis, a life...

Study points to a phosphorylation pathway that may contribute to the development of lung injury and fibrosis A study by researchers at the University of California, San Diego School of Medicine may lead to a way to prevent the progression, or induce the regression, of lung injury that results from use of the anti-cancer chemotherapy drug Bleomycin. Pulmonary fibrosis caused by this drug, as well as Idiopathic Pulmonary Fibrosis (IPF) from unknown causes, affect nearly five million people...

Small device works with air, pure oxygen not needed An artificial lung built by Cleveland researchers has reached efficiencies akin to the genuine organ, using air "“ not pure oxygen as current man-made lungs require - for the source of the essential element. Use in humans is still years away, but for the 200 million lung disease sufferers worldwide, the device is a major step toward creating an easily portable and implantable artificial lung, said Joe Potkay, a research assistant...

(Ivanhoe Newswire) -- Taste receptors in the lungs? Researchers have discovered that bitter taste receptors aren't just in the mouth, but in the lungs as well. Learning about the taste receptors could revolutionize the treatment of asthma and other obstructive lung diseases. "The detection of functioning taste receptors on smooth muscle of the bronchus in the lungs was so unexpected that we were at first quite skeptical ourselves," the study's senior author, Stephen B. Liggett, M.D.,...

University of Maryland School of Maryland researchers show bitter compounds open lung airways better than current drugs Taste receptors in the lungs? Researchers at the University of Maryland School of Medicine in Baltimore have discovered that bitter taste receptors are not just located in the mouth but also in human lungs. What they learned about the role of the receptors could revolutionize the treatment of asthma and other obstructive lung diseases. "The detection of functioning taste...

Researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University, Harvard Medical School and Children's Hospital Boston have created a device that mimics a living, breathing human lung on a microchip. The device, about the size of a rubber eraser, acts much like a lung in a human body and is made using human lung and blood vessel cells. Because the lung device is translucent, it provides a window into the inner-workings of the human lung without having to invade...

Human stem cells administered intravenously can restore alveolar epithelial tissue to a normal function in a novel ex vivo perfused human lung after E. coli endotoxin-induced acute lung injury (ALI), according to research from the University of California San Francisco. The findings were reported at the ATS 2010 International Conference in New Orleans. ALI is a common cause of respiratory failure in the intensive care units, often leading to death. It can be caused by both direct injury such...

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...

Using both animal and human cells, Duke University Medical Center scientists have demonstrated that a single lung cell can become one of two very different types of airway cells, which could lead to a better understanding of lung diseases.From this single "basal" cell, a small, squat stem cell that divides to replenish the lung lining layer, scientists created 3-D hollow spheres that were lined inside with both ciliary and secretory cells. This 3-D model can be used to study dynamic processes...

 More than one kind of stem cell is required to support the upkeep and repair of the lungs, according to a new study published in the journal Cell Stem Cell.Scientists at Duke University Medical Center painstakingly followed and counted genetically labeled cells in the mouse lung for over a year, under differing conditions, to learn more about natural renewal and healing processes. This information may shed light on what goes wrong in conditions like lung cancer, chronic bronchitis and...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
