  • Patent number: 10231976
    Abstract: Provided are methods and kits for administering progestogen as a glucocorticoid sensitizer to restore corticosteroid sensitivity or reverse the glucocorticoid insensitivity or enhance glucocorticoid sensitivity, in order to treat one or more glucocorticoid insensitivity related diseases or conditions. For example, these include methods for reversing the glucocorticoid insensitivity in a subject having no history of menstrual cycle-related exacerbation or allergy to self-hormones, particularly progesterone, such as premenstrual or perimenstrual deterioration in the symptoms, e.g., premenstrual worsening of atopic dermatitis or premenstrual exacerbations of asthma, and exhibiting relatively or totally refractory responses to glucocorticoid therapy, e.g., glucocorticoid resistance. The methods and kits provide for the administration of a sex hormone to the subject who is corticosteroid dependent or corticoid resistant or unresponsive or intolerant to corticosteroids.

  • Patent number: 7046910
    Abstract: Progressive I-slice refreshed MPEG data streams are transcoded to I-frame based MPEG data streams to enable trick play modes on a television appliance, such as pause, scan forward, scan backward, jump, or still frame displays for use, e.g., in film indexing (chapters). A progressive I-slice refreshed MPEG data stream 10 having I-slices distributed over multiple P-frames is received by a television appliance 300. The P-frames are decoded at decoder 220 to recover the I-slices which make up a complete I-frame. The recovered I-slices are assembled (e.g., by processor 230) into a complete I-frame. The complete I-frame is encoded at an encoder 250. A selected P-frame in the MPEG data stream is replaced with the encoded I-frame (e.g., via multiplexer 255) to provide an encoded I-frame based data stream 200. The I-frame based data stream is stored (e.g., in memory 240) for trick play mode use.

  • Patent number: 5413579
    Abstract: A set of surgical instruments which comprises a saw guide and a drill guide respectively for guiding a saw blade cutting a bone and for guiding a drill bit for thereafter forming a passage in the bone. The saw guide has a seat formation for seating against the bone, and a guide formation for guiding the saw. The drill guide comprises a bit guide and an anchor to align the bit guide relative to the cut. Also provided are a saw guide and a drill guide; and a method of carrying out an osteotomy procedure by making an oblique cut through a long bone at a position where bone portions which are misaligned intersect each other to provide two bone fragments, whereafter they are loosely bolted together and then rotated about the axis provided by the bolting until the misalignment is reduced, after which they are bolted tightly together.
