Machine-learning and neuroimaging techniques have been used to accurately distinguish between individuals with Dissociative Identity Disorder (DID) and healthy individuals, on the basis of their brain structure, in new research part funded by the NIHR Maudsley Biomedical Research Centre and published in The British Journal of Psychiatry. Researchers performed MRI (magnetic resonance […]

Researchers have discovered that a hormone, fibroblast growth factor 21 (FGF21), is extremely elevated in mice with liver disease that mimics the same condition in patients with methylmalonic acidemia (MMA), a serious genomic disorder. Based on this finding, medical teams treating patients with MMA will be able to measure FGF21 levels to […]

Scientists at Washington University School of Medicine in St. Louis have developed a new tool described as a “flight data recorder” for developing cells, illuminating the paths cells take as they progress from one type to another. Scientists hope to one day be able to take skin cells from a […]

The discovery of three biomarkers that detect mild cognitive impairment and Alzheimer’s has the potential to lead to the development of a saliva test to diagnose the chronic neurodegenerative disease. University of Alberta scientists Liang Li and Roger Dixon examined saliva samples from three sets of patients: those with Alzheimer’s, those with mild cognitive […]

The idea of a cancer vaccine is something researchers have been working on for over 50 years, but until recently they were never able to prove exactly how such a vaccine would work. Now, a team of researchers at the Institute for Research in Immunology and Cancer (IRIC) at Université de […]

The venom of insects such as wasps and bees is full of compounds that can kill bacteria. Unfortunately, many of these compounds are also toxic for humans, making it impossible to use them as antibiotic drugs. After performing a systematic study of the antimicrobial properties of a toxin normally found […]

Newborns with vitamin D deficiency have an increased risk of schizophrenia later in life, a team of Australian and Danish researchers has reported. The discovery could help prevent some cases of the disease by treating vitamin D deficiency during the earliest stages of life. The study, led by Professor John McGrath from The […]

Postmenopausal women with higher levels of body fat have a significantly increased risk of developing breast cancer even if they have a normal body mass index (BMI), according to a study published Dec. 6 in JAMA Oncology. BMI is a measure of body mass based only on height and weight; […]

Older adults who added hazelnuts to their diet for a few months significantly improved their levels of two key micronutrients, new research at Oregon State University indicates. In the study, 32 people age 55 and older ate about 57 grams of hazelnuts – 2 ounces or about one-third cup – […]

Girls exposed to chemicals commonly found in toothpaste, makeup, soap and other personal care products before birth may hit puberty earlier, according to a new longitudinal study led by researchers at UC Berkeley. The results, which were published in the journal Human Reproduction, came from data collected as part of the […]

When traveling in space, astronauts experience physiological changes normally associated with aging, such as bone loss, muscle deterioration and altered immune systems. When the astronauts return to Earth, the changes often reverse. To better understand the relevance of the astronauts’ experience to human health — both on the ground and […]

Postmenopausal women who have experienced loss of all teeth are at higher risk of developing high blood pressure, according to a University at Buffalo study published Dec. 4 in the American Journal of Hypertension. Multiple studies have suggested an association between periodontal disease and tooth loss with hypertension, but the […]

Nature is so complex that natural molecules used for i.e. cancer treatment still can’t be produced by chemical synthesis. Today, major chemical and pharmaceutical companies harvest large amounts of rare plants and seeds in order to extract valuable substances. But the production methods based on extracts from natural resources are […]

Researchers studying Alzheimer’s disease have created an approach to classify patients with Alzheimer’s disease, a finding that may open the door for personalized treatments. “Alzheimer’s, like breast cancer, is not one disease,” said lead author Shubhabrata Mukherjee, research assistant professor of medicine at the University of Washington School of Medicine. ”I […]

Researchers at the University of Missouri have unraveled how a cancer-critical enzyme is positioned on cell surfaces. The enzyme enables tumor cells to tunnel through collagen, creating a convenient path for tumors to spread cancer throughout the body. This breakthrough is an important step toward the development of pharmaceuticals that can prevent […]
