Multiscale modelling of nanoparticle distribution in a realistic tumour geometry following local injection

Radiosensitizers have proven to be an effective method of improving radiotherapy outcomes, with the distribution of particles being a crucial element to delivering optimal treatment outcomes due to the short range of effect of these particles. Here we present a computational model for the transport of nanoparticles within the tumour, whereby the fluid velocity and particle deposition are obtained and used as input into the convection-diffusion equation to calculate the spatio-temporal concentration of the nanoparticles. The effect of particle surface charge and injection locations on the distribution of nanoparticle concentration within the interstitial fluid and deposited onto cell surfaces is assessed. The computational results demonstrate that negatively charged particles can achieve a more uniform distribution throughout the tumour as compared to uncharged or positively charged particles, with particle volume within the fluid being 100% of tumour volume and deposited particle volume 44.5%. In addition, varying the injection location from the end to the middle of the tumour caused a reduction in particle volume of almost 20% for negatively charged particles. In conclusion, radiosensitizing particles should be negatively charged to maximise their spread and penetration within the tumour. Choosing an appropriate injection location can further improve the distribution of these particles

Beyond Indigenization: International Dissemination of Research by Majority-World Psychologists

Analyses of the affiliations of authors of articles published in targeted samples of North American and international journals revealed trends toward increasing international publication by psychologists from countries outside the U.S., i.e., from countries in the rest of the world (ROW). Relatively few of these ROW publications came from psychologists from developing countries. Because developing countries are most numerous and represent the majority of the people in the world, their contribution to the world of psychology is important. Following a summary presentation of data for each journal for psychologists from East Asia, Latin America and the Caribbean, and South Asia (primarily India), the factors differentially deterring or promoting international publication within each region are discussed.1 Consideration of the extent to which research contributions are differentially influenced by the national economy, national language, and the state of discipline development raise questions and provide insights into the international dissemination of majority-world research
