  • HORIZONTAL SEMICONDUCTOR DEVICE
    Publication number: 20170207085
    Abstract: A horizontal semiconductor device includes an electrically conductive substrate having a first surface, a buffer layer disposed on the first surface of the substrate, an epitaxial unit disposed on the buffer layer opposite to the substrate, a first electrode unit disposed on the epitaxial unit, and a second electrode unit. The substrate has an exposed region that is exposed from the buffer layer and the epitaxial unit. The second electrode unit includes a first conductive member disposed on the epitaxial unit and spaced apart from the first electrode unit, and a second conductive member extending from the first conductive member to the exposed region.

  • Peptides and calcium regulation in mammalian cells
    Patent number: 8022177
    Abstract: Calcium channels in a variety of tissues may contain different subunits, including several different ? (gamma) subunits. We report studies regarding structural features of certain gamma subunits, for example the N-terminal first transmembrane domain (TM1) of the subunit ?6. We disclose that certain structural motifs, for example a GxxxG-like structural motif as described herein, can mediate subunit function for calcium channels. A particular peptide motif that has been identified as significant for the ability to mediate a decrease in calcium current is GxxxA. Compositions and methods are disclosed which are useful in modifying calcium regulation in mammalian cells. In various embodiments, calcium current is modified.
