How the appendix could hold the keys to Parkinson ’s disease, and materials scientists mimic nature

For a long time, Parkinson ’s disease was thought to be merely a disorder of the nervous system. But in the past decade researchers have started to look elsewhere in the body for clues to this debilitating disease—particularly in the gut. Host Meagan Cantwell talks with Viviane Labrie of the Van Andel Institute in Grand R apids, Michigan, about new research suggesting people without their appendixes have a reduced risk of Parkinson’s. Labrie also describes the possible mechanism behind this connection. And host Sarah Crespi talks with Peter Fratzl of the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, about what materials scientists can learn from nature. The natural world might not produce innovations like carbon nanotubes, but evolution has forged innumerable materials from very limited resources—mostly sugars, proteins, and minerals. Fratzl discusses how plants make time-release see dpods that are triggered by nothing but fire and rain, the amazing suckerin protein that comprises squid teeth, and how cicadas make their transparent, self-cleaning wings from simple building blocks. Fratzl’s review is part of a special section in Science on composite materials. Read the whole p ackage, including a review on using renewables like coconut fiber for building cars and incorporating carbon nanotubes and graphene into composites.

(Digestive Disease Week) Patients who had their appendix removed were more likely to develop Parkinson's disease than those whose appendix remained in place, according to the largest study to address the relationship between the two conditions. The retrospective study involving more than 62 million patient records from 26 health systems will be presented at Digestive Disease Week ® (DDW) 2019.

This study therefore recruited patients with AD, PDD, and DLB, in comparison with HC, with two main objectives: (1) exploration of the disrupted glucose metabolism network topology (brain network) and comparison of related parameters, and (2) exploration of hemispheric asymmetry. Materials and Methods Participants Metabolic brain images were acquired using 18F-labeled fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) from four groups, including 22 healthy subjects, and 22, 18, and 22 patients with AD, PDD, and DLB, respectively. Subjects were recruited from the PET Center of Huashan Hospital, Shanghai, Chi...
