Brain banking in the United States and Europe: Importance, challenges, and future trends.

In recent years, brain banks have become valuable resources for examining the molecular underpinnings of various neurological and psychological disorders including Alzheimer disease and Parkinson disease. However, the availability of brain tissue has significantly declined. Proper collection, preparation, and preservation of postmortem autopsy tissue are essential for optimal downstream brain tissue distribution and experimentation.

Drosophila muller f elements maintain a distinct set of genomic properties over 40 million years of evolution.

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D.
