A genetic perspective on African prehistory

The various genetic systems (mitochondrial DNA, the Y chromosome and the genome-wide autosomes) indicate that Africa is the most genetically diverse continent in the world and the most likely place of origin for anatomically modern humans. However, where in Africa modern human arose and how the current genetic makeup within the continent was shaped is still open to debate. Here, we summarise th...

Towards the Atlas of human African trypanosomiasis

BACKGROUND Updated, accurate and comprehensive information on the distribution of human African trypanosomiasis (HAT), also known as sleeping sickness, is critically important to plan and monitor control activities. We describe input data, methodology, preliminary results and future prospects of the HAT Atlas initiative, which will allow major improvements in the understanding of the spatial di...

SU-E-J-106: Atlas-Based Segmentation: Evaluation of a Multi-Atlas Approach for Lung Cancer.

PURPOSE Previous studies have shown atlas-based segmentation using a single best matched (SBM) atlas subject can significantly reduce contouring time. A new multi-atlas approach has been shown to provide greater accuracy than SBM for cancer of the head and neck. The goal of this study was to evaluate the multi-atlas technique for lung cancer treatment planning. METHODS An institution's SBRT l...
