Exacerbation severity in patients with chronic obstructive pulmonary disease (COPD) can be reliably assessed with the COPD Assessment Test (CAT), according to a new study from the UK. "There is currently no widely accepted standardized method for assessing symptom severity at exacerbations in COPD patients," said Dr Alex J Mackay, MBBS, MRCP, clinical research fellow at the Academic Unit of Respiratory Medicine, University College London. "Incorporating CAT scores into the assessment of...

Discovery may lead to new ways to replace damaged lung tissues with stem cells Scientists at the Salk Institute for Biological Studies have identified a gene that tells cells to develop multiple cilia, tiny hair-like structures that move fluids through the lungs and brain. The finding may help scientists generate new therapies that use stem cells to replace damaged tissues in the lung and other organs. "Cells with multiple cilia play a number of important roles, including moving fluids...

National Jewish Health researchers and their colleagues in the COPDGene research consortium report that a computerized form of radiology, known as quantitative CT, can offer valuable prognostic information for patients and doctors beyond the standard breathing tests most commonly used to evaluate chronic obstructive pulmonary disease (COPD). “Our findings indicate that quantitative CT scans can help identify patients at greater risk for damaging exacerbations of their disease,”...

Research findings challenges medical textbooks A ground-breaking international study into the ways lungs grow and develop has challenged existing medical understanding that our lungs are completely formed by the age of three. The researchers, led by a team at the University of Leicester, put forward a theory for the first time based on research evidence that new air sacs, called alveoli, are constantly being formed. This contradicts information in most medical textbooks that explain...

(Ivanhoe Newswire) — The world´s first artificial trachea transplant seeded with stem cells proved to be a success after being done on Andemariam Teklesenbet Beyene at the Karolinska University Hospital, Stockholm, Sweden. Beyene had a tracheal tumor that extended to the lowest 5cm of the trachea along with both bronchi meaning that surgical removal of the tumor alone would not keep the patient alive. The removed section was essential for life and therefore had to be replaced....

Working together, scientists and clinicians make research breakthrough that paves the way for novel therapies for respiratory diseases Scientists at A*STAR'S Genome Institute of Singapore (GIS) and Institute of Molecular Biology (IMB), have made a breakthrough discovery in the understanding of lung regeneration. Their research showed for the first time that distal airway stem cells (DASCs), a specific type of stem cells in the lungs, are involved in forming new alveoli to replace and...

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...
