Gut diseases such as inflammatory bowel disease (IBD) are increasingly prevalent worldwide, especially in industrialised countries. In 2015 alone, 250,000 people in the UK were diagnosed with IBD, and 3 million in the United States (1, 2). Symptoms can include pain and swelling of the stomach, bloody diarrhoea, weight loss and extreme tiredness.

A particularly aggressive, metastasizing form of cancer, HER2-positive breast cancer, may be treated with nanoscopic particles “imprinted” with specific binding sites for the receptor molecule HER2. As reported by Chinese researchers in the journal Angewandte Chemie, the selective binding of the nanoparticles to HER2 significantly inhibits multiplication of the tumor cells.

Intermittent fasting is known to improve sensitivity to the blood glucose-lowering hormone insulin and to protect against fatty liver. DZD scientists from DIfE have now discovered that mice on an intermittent fasting regimen also exhibited lower pancreatic fat. In their current study published in the journal Metabolism, the researchers showed the mechanism by which pancreatic fat could contribute to the development of type 2 diabetes.

You could call this a neat discovery. Researchers at the University of Alabama at Birmingham have found that a tissue-specific, non-coding RNA called NEAT1 has a major, previously undescribed role in memory formation. The findings are presented in a paper published in Science Signaling on July 2.

Antidepressants reduce deaths by more than a third in patients with diabetes and depression, according to a study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

By using eye-tracking technology to automatically control a pair of autofocus lenses, engineers have created a prototype for “autofocals” designed to restore proper vision in people who would ordinarily need progressive lenses.

Lung cancer cells use antioxidants, endogenous or dietary, to spread in the body by activating a protein called BACH1 and increasing the uptake and use of sugar, Swedish and American researchers report in two independent studies. The studies, which are published in the eminent scientific journal Cell, pave the way for new therapeutic strategies for lung cancer.
