    “…The antenna is fully integrated with the rectifier on a single chip, thus enabling antenna miniaturisation due to the high dielectric constant of GaAs and spiral design. This miniaturisation enables the design to be fabricated economically on a GaAs substrate whilst being comparable in size to a 15-gauge needle, thus unlocking applications in medical implants. …”

    “…Pronase first solubilized the linkers and C tubules of the triplets, then attacked the protein portion of the axosome, a localized portion of the ciliary axoneme adjacent to the distal end of the basal body, the rim fiber, and newly described lumen spiral complex. Prolonged pronase treatment disrupted the remaining microtubular elements, basal body plates, and cartwheel. …”

    “…The microfilaments are not actin, as based on: (a) their small diameter, (b) the lack of decoration with heavy meromyosin, and (c) their ability to coil, spiral or fold during contraction. By the use of Thorotrast, we were able to demonstrate that the cell surface is deeply infolded, extending all the way to the hip joint. …”
