Alzheimer's disease could be linked to exposure to air pollution, study reveals
Experts have discovered the presence of magnetic nanoparticles - strongly magnetic toxic iron-based materials - which have previously been associated with the development of neurodegenerative diseases, such as Alzheimer's, in the human brain.But now researchers from the UK and Mexico are suggesting the features of the nanoparticles suggest they are less likely to have been formed naturally in the body and more likely to have come from an outside source - which they say could be air pollution.Researchers found the particles in the brains of a group of people from Mexico and Manchester, some of whom had Alzheimer's when they died.Alzheimer's disease is caused by a build up of proteins in the brain, leading to the loss of brain tissue, the death of nerve cells and a shortage of important brain chemicals.

New treatment for Crohn's disease could save sufferers from painful symptoms
New treatment for Crohn's disease could save sufferers from painful symptoms
Crohns disease is a long-term condition that causes inflammation of the lining of the digestive sysThe condition, which is currently incurable, is caused by inflammation that blocks the intestines and affects around 115,000 people in the UK.Symptoms include diarrhoea, severe abdominal pain and extreme tiredness and often leads to repeated surgery to remove blocked sections of the gut.People with Crohn's disease can go for long periods without experiencing symptoms or but the periods where symptoms flare up.However, scientists believe that drugs already on the shelves could prevent the inflammation that leads to fibrosis - or tissue scarring - which causes the blockages.

New discovery could potentially lead to treatments for Crohn's disease
Scientists at the University of British Columbia have made a discovery that could potentially lead to treatments for a debilitating complication of Crohn's disease.Crohn's disease is an inflammatory bowel disease in which the intestines of some patients can become blocked by thickened and scarred connective tissue--a condition known as fibrosis.When fibrosis occurs, surgical intervention is required to restore proper digestion.Repeated surgeries are not uncommon in Crohn's patients.
