  • Publication number: 20160303165
    Abstract: Administration of human umbilical cord blood cells (HUCBC) or HUCBC-derived plasma is used to treat amyloid-based diseases, such as Alzheimer's disease, Huntington's disease, cerebral amyloid antigopathy, and type-II diabetes. Modulating inflammatory reactions by infusing HUCBC resulted in a marked reduction of amyloid plaques and immune-associated cellular damage. HUCBC infusion also significantly reduced cerebral amyloid angiopathy in mice models. These effects were associated with suppression of the CD40-CD40L interaction and a reduction in surface expressed CD-40 was observed on immune cells. Further, A? phagocytic activity was increased and soluble and insoluble A? protein levels were modulated by treatment. HUCBC-infused sera also significantly increased phagocytosis of A?1-42 peptide and inhibited immune cell CD40 expression and reduced cerebral amyloid angiopathy.

  • Publication number: 20160225678
    Abstract: Techniques for measuring and testing a semiconductor wafer during semiconductor device fabrication include designating a test area on the top surface of the wafer and etching a first rectangular trench and a second rectangular trench on the top surface of the wafer in the test area. The trenches are oriented such that a length of the first trench is perpendicular to a length of the second trench, and positioned such that the length of the first trench, if extended, intersects the length of the second trench. A silicon-germanium compound is deposited into the first trench and the second trench, and a test pad is removed from the test area of the wafer. The test pad includes a side surface where both the first trench and the second trench are exposed. The side surface of the test pad is scanned with a transmission electron microscope to take measurements of the silicon-germanium.
