“If we would like to have the ability to ship mRNA, then we want a mechanism to be simpler at it as a result of all the pieces that’s been used to this point offers you a really small fraction of what could be the optimum effectivity,” says professor Paula Hammond. Credit score: Bryce Vickmark By delivering strands of genetic materials often called messenger RNA (mRNA) into cells, researchers can induce the cells to provide an y protein encoded by the mRNA. This system holds nice potential for administering vaccines or treating illnesses corresponding to most cancers, however reaching environment friendly supply of mRNA has confirmed difficult. Now, a workforce of MIT chemical engineers, impressed by the best way that cells translate their very own mRNA into proteins, has designed an art...

"These results need to be confirmed with additional studies, but the results are intriguing," said study author Brenda C.T. Kieboom, MD, MSc, of Erasmus University Medical Center in Rotterdam, the Netherlands. "Since the current treatment and prevention options for dementia are limited, we urgently need to identify new risk factors for dementia that could potentially be adjusted. If people could reduce their risk for dementia through diet or supplements, that could be very beneficial." The study involved 9,569 people with an average age of 65 who did not have dementia whose blood was tested for magnesium levels. The participants were followed for an average of eight years. During that time, 823 people were diagnosed with dementia. Of those, 662 people had Alzheimer's disease. The participants were divided into five groups based on their magnesium levels. Both those with the highest and the lowest levels of magnesium had an increased risk of dementia , com...

As many as one in five adults meet the criteria for irritable bowel syndrome (IBS), a disorder that can cause chronic abdominal pain, gas, diarrhea, and constipation. Many patients with IBS try diets based on blood tests that claim to identify foods that trigger their symptoms. However, the majority of these food intolerance tests have not been validated by rigorous study, said the researchers. The Yale team conducted a double-blind, randomized clinical trial of 58 patients with IBS. For each individual, the researchers collected blood samples and used a specific test that measures immune cell activation in response to individual foods. The study participants were then put on individualized diets that either restricted foods consistent with test results or restricted foods inconsistent with test results. After several weeks on the individualized diets , participants were assessed for IBS symptoms and quality of life. The research team found that while both sets of participants e...

Inflammatory bowel disease (IBD) is a term used to describe two conditions that involve inflammation of the gut: ulcerative colitis and Crohn's disease . People of any age can get IBD, but it's usually diagnosed between the ages of 15 and 40. Previous studies have identified higher rates of cancer among patients with IBD than the general population, but these studies have lacked the population size or follow-up to assess trends in lifetime risks in childhood onset IBD. So a team of international researchers set out to assess the risk of cancer in patients with childhood onset inflammatory bowel disease in childhood and adulthood. They compared 9,405 people living in Sweden who were diagnosed with inflammatory bowel disease before they were 18 years of age with 92,870 healthy individuals (reference individuals) matched for sex, age, birth year, and place of residence. They analysed risk of cancer before 18th birthday, 25th birthday, and throughout the study period (19...
