Scientists reveal mechanism that causes irritable bowel syndrome

Added: 17.01.2021 18:22 | 15 views | 0 comments

Researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel syndrome and other food intolerances. The study was carried out in mice and humans.

Crimped or straight? Lung fiber shape influences elasticity

Added: 17.01.2021 17:51 | 4 views | 0 comments

Stiff collagen and stretchy elastin fibers packed together in rows allow the respiratory system to stretch and snap back into shape. Scientists previously thought these fibers govern the mechanics of the airways due to their composition. New research has instead observed that differences in the shape and form of tissue fibers influence respiratory elasticity. These findings will help scientists better understand lung diseases, from chronic diseases like COPD to the lung ailment associated with vaping.

E-cigs can trigger same lung changes seen in smokers, emphysema

Added: 17.01.2021 17:51 | 4 views | 0 comments

Scientists found that the lungs of vapers -- like the lungs of smokers -- have elevated levels of protease enzymes, a condition known to cause emphysema in smokers. The researchers also found that the nicotine in vaping liquids is responsible for the increase in protease enzymes.

Low level exposure to air pollution is harmful, mouse model shows

Added: 17.01.2021 17:51 | 2 views | 0 comments

Scientists investigating the effect of air pollution on lung health, in an animal model, have concluded that even low levels of exposure can have a detrimental effect on the lungs. They say the results have implications for government agencies responsible for urban planning.

Can scientists change mucus to make it easier to clear, limiting harm to lungs?

Added: 17.01.2021 17:51 | 3 views | 0 comments

For people with conditions such as cystic fibrosis and COPD, mucus can get too thick and sticky; coughing alone can't clear it. Infections develop, leading to severe chronic disease and early death. Now, for the first time, scientists have shown why coughing often cannot tear mucus apart and away from the airway lining. And they showed how to make mucus thinner and less sticky so coughing can become a therapeutic aid.

Blood vessel cells implicated in chronic inflammation of obesity

Added: 16.01.2021 5:19 | 6 views | 0 comments

When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity. Now, scientists have discovered a type of cell responsible, at least in mice, for triggering this inflammation in fat tissue. Their findings could eventually lead to new ways to treat obesity.

Even skin shielded from the sun accumulates genomic DNA changes from UV light

Added: 16.01.2021 4:17 | 21 views | 0 comments

For the first time, scientists have measured the different types of genomic DNA changes that occur in skin cells, finding that mutations from ultraviolet (UV) light is especially common, but Black individuals have lower levels of UV damage compared to white people.

Hard to crack research reveals how crop roots penetrate hard soils

Added: 16.01.2021 4:17 | 24 views | 0 comments

Scientists have discovered a signal that causes roots to stop growing in hard soils which can be 'switched off' to allow them to punch through compacted soil -- a discovery that could help plants to grow in even the most damaged soils.
