A study by biomedical scientists at the University of Leicester has revealed for the first time that rice bran could reduce the risk of intestinal cancer. The research in the University's Department of Cancer Studies and Molecular Medicine has not been tested on humans, but research in the laboratory has produced promising results.
The research has been published in the British Journal of Cancer. The results of a controlled laboratory study in a preclinical model of gastrointestinal adenoma demonstrated that consumption of a high daily dose of stabilized rice bran caused an average 51% reduction in the number of precancerous adenomas in the intestinal tract.

British researchers have discovered that arthritis pain, unlike that induced as part of an experiment, is processed in the parts of the brain concerned with emotions and fear. A research team at The University of Manchester led by Bhavna Kulkarni has captured the first images of how the brain processes arthritis pain, using positron emission tomography (PET) scanners,science news website AlphaGalileo reported on Friday.
Previous neuro-imaging studies show that experimentally-induced pain is processed in at least two brain networks, collectively known as the 'pain matrix', with the 'medial pain system' processing the emotional aspects such as pain's unpleasantness and the 'lateral pain system' processing the pain's intensity, location and duration. The researchers wanted to see whether the same applied to the clinical pain suffered by people with conditions like arthritis, as no direct comparisons of experimental and clinical pain had been undertaken in the same group of patients.
