We recently discovered a novel subset of beta cells that resemble immature beta cells during pancreas development. We named these “virgin” beta cells as they do not stem from existing mature beta cells. Virgin beta cells are found exclusively at the islet periphery in areas that we therefore designated as the “neogenic niche.” As beta cells are our only source of insulin, their loss leads to diabetes. Islets also contain glucagon‐producing alpha cells and somatostatin‐producing delta cells, that are important for (...) glucose homeostasis and form a mantle surrounding the beta cell core. This 3D architecture is important and determines access to blood flow and innervation. We propose that the distinctive islet architecture may also play an important, but hitherto unappreciated role in generation of new endocrine cells, including beta cells. We discuss several predictions to further test the contribution of the neogenic niche to beta cell regeneration. (shrink)

E-therapy is fast becoming an inevitable addition to counseling due to the increased use and accessibility, the internet and advances in e-therapy technology in the U.S. With the growth of any method of treatment, awareness of ethical concerns regarding best practices is a necessity. E-therapy has unqiue ethical challenges that mental health professionals should be aware of when utilizing computer mediated counseling. Specifi cally, there are fi ve common ethical concerns of on-line counseling that should be addressed during the informed (...) consent process: appropriate concerns for e-therapy, the possibility of misunderstanding, maintenance of professional boundaries, issues of confi dentiality, and interruption of services. This paper also calls for professional organizations to update their ethical guidelines to refl ect the changing ethical concerns in e-therapy, as well as enact better enforcement of these guidelines.
