Enhancing the ability of the lungs to regenerate following injury could revolutionize the treatment of a wide range of different diseases. In this issue, Kumar et al. (2011) and Ding et al. (2011) dissect the cellular and molecular mechanisms of murine lung regeneration following injury and pro...
Monolayers of the lipid arachidic acid (C 20) and of the phospholid dimyristolyphosphatidic acid (PMDA) have been studied by X-ray reflection and diffraction technique, using a purpose-built Langmuir trough installed at the sample stage of our high-resolution X-ray diffractometer at the DORIS ...
The method for assessing the air-filling of the lungs consists in measuring the diaphragm length and the distance between the points of its attachment to the thoracic wall in X-ray film obtained at the specified phase of the respiratory cycle. Then the ratio of these two distances is ...
Yuanyan nebulizer is a drug delivery device used to administer medication in the form of a mist inhaled into the lungs, Nebulizers are commonly used for the treatment of cystic fibrosis, asthma, COPD and other respiratory diseases. It is widely use in th
So when we are deep on air, it becomes harder for us to fill our lungs. More importantly, it also becomes harder to empty them between each breath. This leads to the third issue. The primary consequence of reduced breathing efficiency is that we retain more carbon dioxide (CO₂) in ...

latent infection and active infection. In mycobacterium tubercle bacteria/Type M (mycobacterium) tuberculosis, only an individual with active TB of the lungs or airways can spread the disease by coughing and sneezing. Transmission is most likely to occur when individuals are in close proximity for ...
