Eating Disorders and the Brain

Eating disorders are biologically based brain illnesses influenced by environmental and psychological factors. Environmental risk factors for developing an eating disorder include weight and appearance pressures, media messaging, and weight bullying. Biological factors include dieting/food exposure, genetics, neurochemistry, neurobiology, and hormones (notably estrogen). Psychological factors include stress, life transitions, identity, trauma, anxiety, depression, and substance use. While risk factors predispose certain individuals to eating disorders, precipitating factors such as significantly altering how one eats or stressful life events make may an individual more likely to develop and eating disorder. Once an eating disorder is present, maintenance factors take over. These factors that maintain an eating disorder include biological changes that occur as a result of disordered eating and psychological factors that are connected to the eating disorder behaviors that then turn and reinforce a person’s repetitive, disordered behaviors. What makes certain individuals vulnerable to developing an eating disorder? Eating behavior is mediated by a large network of interacting neural circuits that include numerous areas of the brain, including the prefrontal cortex, anterior cingulate, insula, and the amygdala. We know that our eating behavior is determined by several signals that come into our brain through our mouth or through our gut. The experience of eating (Does thi...

In this study, five machine learning algorithms and twelve types of molecular fingerprints were employed to generate QSAR discriminant models for mitochondrial toxicity. A threshold moving method was adopted to resolve the imbalance issue in the training data. Consensus of the models by an averaging probability strategy improved prediction performance. The best model has correct classification rates of 81.8% and 88.3% in ten-fold cross validation and external validation, respectively. Substructures such as phenol, carboxylic acid, nitro and arylchloride were found informative through analysis of information gain and freque...

In this study, mushroom residue was adding in lead-zinc slag to enhance the phytoremediation potential of P. fortunei, the effects of three treatments (lead-zinc slag, red soil, lead-zinc slag + 10% (m/m) mushroom residue) on the growth, physiology and microstructure of P. fortunei were determined. The results showed that the addition of mushroom residue increased the biomass, plant height and chlorophyll concentration of P. fortunei, indicating that the addition of mushroom residue can facilitate the growth of P. fortunei. Moreover, the proportions of oxalate-Pb forms and phosphate-Zn were do...

Abstract Zeranol is an approved but controversial growth-promoting agent for livestock in North America. It is a mycotoxin metabolite secreted by the Fusarium family fungi. The regulatory bodies in this region have established the acceptable daily intake and exposure below the level would not significantly increase the health risk for humans. However, their European counterparts have yet to establish an acceptable level and do not permit the use of this agent in farm animals. Given the growth-promoting ability of zeranol, its effect on energy metabolism was investigated in the current study. Our results indicated ...
