Lifestyle is a threat to gut bacteria: Ötzi proves it, study shows


The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may be associated with the increased prevalence, in Western countries, of complex conditions like allergies, autoimmune and gastrointestinal diseases, obesity.

Hope for millions of IBS sufferers as research identifies cause of pain as 'gut itch'

This is big news for irritable bowel syndrome (IBS) patients: 11% of the world's population suffers from IBS, but the fight against chronic pain has taken a major step forward with scientists identifying receptors in the nervous system which cause the condition in the hope of developing effective treatments.

When blood vessels are overly permeable

In Germany alone there are around 400,000 patients who suffer from chronic inflammatory bowel diseases. For the first time, researchers have discovered that dysfunctions in blood vessels play a significant role in the development of such diseases. In experimental model systems, the progression of the disease slowed down significantly by eliminating these dysfunctions.

Gut bacteria 'fingerprint' predicts radiotherapy side effects

Taking a 'fingerprint' of the mix of bacteria in the gut can indicate how susceptible individual cancer patients are to gut damage as a result of radiotherapy for prostate and gynaecological cancers, a new study shows. Researchers showed that having a reduced diversity of gut bacteria was associated with an increased risk of both immediate and delayed damage to the gut following radiotherapy.

New AI method may boost Crohn's disease insight and improve treatment

Scientists have developed a computer method that may help improve understanding and treatment of Crohn's disease, which causes inflammation of the digestive tract. The study used artificial intelligence to examine genetic signatures of Crohn's in 111 people. The method revealed previously undiscovered genes linked to the disease, and accurately predicted whether thousands of other people had the disease.

Adult fly intestine could help understand intestinal regeneration

Intestinal epithelial cells (IECs) are exposed to diverse types of environmental stresses such as bacteria and toxins, but the mechanisms by which epithelial cells sense stress are not well understood. New research has found that Nox-ROS-ASK1-MKK3-p38 signaling in IECs integrates various stresses to facilitate intestinal regeneration.
