Proopiomelanocortin (POMC) is a neuroendocrine precursor protein which is processed at paired basic amino acids in a tissue-specific manner. To study this phenomenon, a vaccinia virus recombinant, which directs the synthesis of mouse POMC (VV:mPOMC) was constructed and used to infect epithelial (BSC-40) and endocrine (Rin m5F) cell lines. Bona fide mPOMC(More)
Neisseria meningitidis is an inhabitant of the mucosal surfaces of the human nasopharynx. We recently demonstrated that the secreted meningococcal Two-partner secretion protein A (TpsA) is involved in interbacterial competition. The C-terminal end of the large TpsA protein contains a small toxic domain that inhibits the growth of target bacteria. The(More)
Fungi are strongly affected by their physical environment. Microfabrication offers the possibility of creating new culture environments and ecosystems with defined characteristics. Here, we report the isolation of a novel member of the fungal genus Acremonium using a microengineered cultivation chip. This isolate was unusual in that it organizes into(More)
In recent years, PowerPoint presentations have become the medium of choice for high school and college educators. Research on images in these presentations has determined that relevant diagrams and graphics improve learning in science and engineering fields; however, there has been little research on images in the humanities, where diagrams are less common.(More)
