In the 20th century, COPD was considered a man's disease. Today, women account for more than half of all COPD deaths. Women who smoke or used to or have a family history of COPD should be tested. Boston, MA (PRWEB) June 03, 2014 Not long ago, chronic obstructive pulmonary disease (COPD) was considered a man's disease. But men no longer hold a monopoly on this chronic and progressive lung condition, according to the May 2014 Harvard Women's Health Watch. Today, more women than...

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body. Now, in a feat of reverse tissue engineering, Stanford University researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform myriad biological tasks. A team of...

Scientists Create Functional Lungs Using Human Stem Cells
2013-12-02 12:40:54

Lee Rannals for redOrbit.com - Your Universe Online Scientists have used human stem cells to create functional lung and airway cells, according to a study published in the journal Nature Biotechnology. The latest research, reported by a team from Columbia University Medical Center (CUMC), could have significant potential for modeling lung disease, screening drugs, studying human lung development, and generating lung tissue for transplantation. "Researchers have had relative success...

-Alveolar macrophage (AM) function plays a critical role in protecting the lungs by removing particulates. -Chronic drinking causes persistent oxidative stress in the lungs, leading to impaired AM function. -A new rodent study shows that chronic drinking appears to intensify lung damage caused by particulate matter. Alveolar macrophage (AM) function plays a critical role in protecting the lungs from particulate matter inhalation by removing particulates from the airway and secreting...

A new genome-wide association study of more than 6,000 people has identified seven new genetic regions associated with pulmonary fibrosis. In findings published online in Nature Genetics on April 14, 2013, researchers at National Jewish Health, the University of Colorado and several other institutions found a number of genes associated with host defense, cell-cell adhesion and DNA repair, which provide clues to possible mechanisms underlying this currently untreatable disease. "This...

Organ-on-a-chip Models Human Disease

[ Watch the Video: Researchers Create Human Breathing Lung-On-A-Chip ] Connie K. Ho for redOrbit.com — Your Universe Online Researchers from Harvard University´s Wyss Institute for Biologically Inspired Engineering recently revealed that they have developed a “lung-on-a-chip” that mimics human diseases and could be the next step forward in terms of research. With the study, the scientists believe that the organ-on-a-chip could eventually take the place of...

Severe lung diseases are among the leading causes of death worldwide. To date they have been difficult to diagnose at an early stage. Within an international collaboration scientists from Munich now developed an X-ray technology to do just that. Now they are working on bringing the procedure into medical practice. Chronic obstructive pulmonary disease (COPD) is considered the fourth most common cause of death in the United States. Usually the precursor to this life-threatening lung disease...

Three-dimensional Mammal Lung Created

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...

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...
