Lung Mucus Gel Prevents Nanoparticles From Getting Through
2012-10-23 10:54:10

Joint press release by the Saarland University and the Helmholtz Centre for Infection Research Mucus coats our airways' internal surfaces. The viscous gel humidifies the lungs and prevents viruses and other small particles like diesel soot from entering the body unchecked. Previously unclear was the extent to which such nanoparticles are able to move through the lungs' mucus. Here, the research evidence was contradictory. Scientists could not explain why, in inhaled medication development,...

Three-dimensional Mammal Lung Created
2012-10-02 15:58:56

Researchers create model of mysterious region Amidst the extraordinarily dense network of pathways in a mammal lung is a common destination. There, any road leads to a cul-de-sac of sorts called the pulmonary acinus. This place looks like a bunch of grapes attached to a stem (acinus means “berry” in Latin). Scientists have struggled to understand more specifically what happens in this microscopic, labyrinthine intersection of alleys and dead ends. To find out, a research...

Mucus Helps Clean Out Human Lungs
2012-08-24 10:53:38

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University of North Carolina, Chapel Hill recently published a study on their work to understand how human lungs clean out mucus from colds and allergy, making the airways free of foreign matter that may be toxic or infectious to the body. The findings, published in a recent issue of the journal Science, will help scientists identify issues related to human lung diseases like asthma, chronic obstructive...

Only 5 percent worried about lung disease, despite it being a leading cause of death New data released by the Forum of International Respiratory Societies (FIRS) to coincide with World Spirometry Day today has revealed a worrying lack of understanding and concern among the public about the world's biggest killer - lung disease, which now claims the lives of almost 4 million people a year. Despite the high incidence of lung disease, research conducted by YouGov across four continents...

CHICAGO, June 27, 2012 /PRNewswire/ -- The American College of Chest Physicians (ACCP), OneBreath®, the COPD Alliance, and thousands of organizations worldwide will unite on World Spirometry Day, June 27, to promote lung health and elevate the status of often overlooked lung conditions, reinforcing the value of spirometry in the diagnosis of these conditions. Spirometry, which translated means "measuring of breath," is one of the few examinations in medicine that is extremely simple to...

The development of convenient, yet physiologically relevant in vitro culture systems is critical to research and development on chronic respiratory diseases such as asthma or COPD, and could accelerate the development of inhaled drug formulations. Vancouver, British Columbia (PRWEB) June 07, 2012 A new culture medium for more physiologically relevant differentiation of human bronchial epithelial cells has been released by STEMCELL Technologies. Cells cultured with PneumaCult-ALI at the...

People who suffer from chronic sinus infections know the warning signs when one might be coming on. Doctors at Baylor College of Medicine say that is a good time to try preventative measures, such as nasal irrigation, to lessen the symptoms or prevent the infection from worsening. Nasal irrigation is the cleansing of the nasal cavity with sterile salt water to flush out excess mucus or debris from the sinuses and nose, such as with the use of a neti pot. Maintain moisture "People are...

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...
