A mobile communication device has an antenna assembly comprising the combination of an inverted-F antenna and a dielectrically-loaded quadrifilar helical antenna, the latter mounted on the distal end of an elongate radiator element of the inverted-F antenna. The dielectrically-loaded antenna has an integral balun on a ceramic antenna core, the balun providing a balanced feed for the radiating elements of the antenna The elongate radiator structure of the inverted-F antenna acts as a feed path for the dielectrically-loaded antenna, the feed path extending along the elongate radiator structure from the balun to a ground connection element of the inverted-F antenna and, thence, to a signal port associated with a grounding connection of the inverted-F antenna Placing the dielectrically-loaded quadrifilar antenna at the end of the radiator structure of the inverted-F antenna rather than alongside the latter substantially reduces breakthrough from a transmitter coupled to the inverted-F antenna to receiving circuitry coupled to the dielectrically-loaded antenna.

Disclosed herein are novel approaches to thyroid cancer therapy. These approaches include methods to enhance thyroid specific gene expression, for example methods to enhance expression of thyroglobulin and/or the Na<+>/I<-> symporter in thyroid cancer cells. Enhanced expression of thyroid-specific genes promotes cellular differentiation and reduces biologically aggressive behavior such as invasion and metastasis. In addition, enhanced expression of thyroglobulin and/or the Na<+>/I<31 > symporter increases the ability of thyroid cancer cells to concentrate iodine or iodide, thereby making the cells more susceptible to radioactive iodine therapy. Also disclosed herein are methods for detecting thyroid neoplasms in a subject, by administering a therapeutically effective amount of a histone deacetylase inhibitor, administering a detectable agent whose uptake or concentration in thyroid cells is increased by administration of the histone deacetylase inhibitor, and detecting the detectable agent.

Essential prerequisites for any injectable product are its sterility, its freedom from pathogens and its freedom from visible particle contamination . . . . These requirements must be satisfied prior to the release of an injectable product batch for sale and use. A major difficulty in responding to these assay requirements is the need for a size sensitivity difference of 100 or greater in determining the presence of viable pathogenic organisms and of non-viable random particle contaminants. The wide dynamic testing range cannot be satisfied in current art with a single non-destructive testing station. The present invention uses a special agitation procedure to generate separate liquid volumes containing the small viable and larger non-viable particle contaminants. This separation makes possible the introduction of sensing systems that have been optimized for each size range and that can operate in parallel without interference.

The generation of a desired non-linear resonance in the toroidal flow of liquid in a cylindrical injectable product is described. The resulting liquid flow pattern generated with an approximately smooth meniscus is down at the walls, across to the center of rotation, up on the center of rotation, across the meniscus to complete the pattern. The controlled flow pattern results in a predictable location for particle of varying mass and hydraulic shape. This predictability of location transforms the problem of particle detection from a chance occurrence to a deterministic task. The deterministic location of particle position is a contributor to the demonstrated capability to measure the size of visible particle range in a range from 33 μm to 1,000 μm with a median deviation of 1% and a maximum deviation from NIST dimensional accuracy of 3%.

The antenna cup has a side wall extending from a base thereof towards an open end thereof, the side wall having a plurality of slots formed therein, a first set of the slots being arranged parallel to a longitudinal axis of the helical element and a second set of the slots being arranged perpendicular to the longitudinal axis of the helical element, the first set of slots being arranged to surround an upper portion of the helical element and the second set of slots being arranged to surround a lower portion of the helical element. The slots present a high impedance wall to surface currents and thereby significantly reduce side lobe radiation. Such an antenna is particular useful in antenna co-location applications, such as cellular telephone and Wi-Fi applications.
