New research from the University of Iowa answers a question that has vexed cystic fibrosis (CF) researchers for almost 25 years: why don't mice with CF gene mutations develop the life-threatening lung disease that affects ...
Pioneering research conducted by the University of Sheffield is paving the way for new treatments which could benefit patients suffering from the fatal lung disease pulmonary arterial hypertension (PAH).
Researchers have identified a link between the expression of a cancer-related gene and cell-surface molecules that protect tumors from the immune system.
Scientists have revealed that a key molecule in breast and lung cancer cells can help switch off the cancers' ability to spread around the body.
A research team from Duke Health has developed an antibody from the body's own immune system that preferentially attacks cancer cells.
Imagine for a moment that you have a tiny but worrisome lung nodule or, say, a growing bulge in a crucial blood vessel. You have no choice but to continue with normal life: going to work, running errands, paying taxes, negotiating ...
(HealthDay)—A new study indicates that 8 percent of patients—or one in 12—already diagnosed with one form of cancer will develop a second unrelated malignancy. The findings were published online July 5 in Cancer.
(Medical Xpress)—A combined team of researchers from Massachusetts General Hospital/Harvard Medical School in the U.S. and Xuanwu Hospital, Capital Medical University in China has found that when neurons in the mouse brain ...
Historically, efforts to improve end-of-life care have focused primarily on patients with cancer. But few studies have looked at the quality of end-of-life care for patients with other serious illnesses, such as lung, kidney ...
The lung or pulmonary system is the essential respiration organ in air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located in the chest on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli.
In order to completely explain the anatomy of the lungs, it is necessary to discuss the passage of air through the mouth to the alveoli. Once air progresses through the mouth or nose, it travels through the oropharynx, nasopharynx, the larynx, the trachea, and a progressively subdividing system of bronchi and bronchioles until it finally reaches the alveoli where the gas exchange of carbon dioxide and oxygen takes place.
The drawing and expulsion of air (ventilation) is driven by muscular action; in early tetrapods, air was driven into the lungs by the pharyngeal muscles, whereas in reptiles, birds and mammals a more complicated musculoskeletal system is used.
Medical terms related to the lung often begin with pulmo-, from the Latin pulmonarius ("of the lungs"), or with pneumo- (from Greek πνεύμων "lung")
