摘要:
Apparatus and instruments for percutaneously extending an existing spinal construct ipsilaterally with an additional spinal construct in a patient are disclosed. The additional spinal construct comprises a rod connector that includes an elongate additional rod integrally attached thereto. The additional rod is placed through an access port in a first orientation generally parallel to the longitudinal axis of the access port and rotated to a different second orientation generally transverse to the longitudinal axis of the access port. During such rotation the additional rod is moved subcutaneously beneath the skin of the patient from the existing spinal rod to an additional bone engaging implant. In another arrangement, the extension of an existing spinal construct in a minimally invasive procedure comprises a rod connector having an offset support for receiving an additional spinal rod that may be placed laterally interiorly or exteriorly of the existing spinal construct.

A surgical instrument for the distraction or compression of bones or bone portions comprises a pair of elongate cross members pivotally coupled for relative movement having at one end a respective pair of handles and at the other end a respective pair of jaws. The jaws are generally parallel to each other and define a first plane within which the jaws are relatively movable, the space on both sides of the plane defining a work space between the jaws. The instrument further comprises a fulcrum supported by at least one of the cross members projecting into the work space and having an axis spaced from the jaws.

摘要:
This invention relates to modified IL-4 mutein receptor antagonists comprising an IL-4 mutein receptor antagonist coupled to polyethylene glycol. Related formulations and dosages and methods of administration thereof for therapeutic purposes are also provided. These modified IL-4 mutein receptor antagonists, compositions and methods provide a treatment option for those individuals afflicted with a respiratory disorder such as asthma by inhibiting IL-4 and IL-13-mediated airway hyperresponsiveness and eosinophilia. More particularly, these antagonists have an increased duration of effect versus unmodified IL-4RA by virtue of a greater plasma half-life.
摘要:
The present invention provides large-scale methods for renaturation of proteins comprising adding a solution of denatured, chemically modified or reduced proteins to a refolding buffer containing sulfate derived from H2SO4 and/or MgSO4 in the presence of guanidine. The present invention further provides methods of isolating a refolded protein at a concentration of about 0.4 to 3.0 gm/L by using a hydrophobic interaction chromatography (HIC) column.

摘要:
A filter housing having radial sealing means is disclosed herein. Upper bosses and lower bosses can be used to attach the head to the sump for easy opening and closing the filter housing when replacing the filter cartridge. The filter housing of the present invention provides simplified filter cartridge changes to minimize process downtime and without recourse to tools. The filter housing contains fluid flow directing mean to facilitate filter cartridge replacement and safety means to prevent removal of the sump when fluid is passing through the sump.

Calibrating a white level in an image scanning device. A target white level is accessed. A high white level is determined for pixel data output by an amplifier. A gain adjustment to the amplifier is determined to correct a portion of an error between the target white level and the high white level. The gain adjustment is applied to the amplifier.
摘要:
Chimeric polypeptide antagonists that include an interleukin-4 (IL-4) mutein linked to an interleukin-9 (IL-9) mutein are provided, as are polynucleotides encoding the IL-4 and IL-9 chimeric mutein antagonists. Also provided are methods of using the chimeric mutein antagonists and encoding polypeptides to reduce or inhibit the responsiveness of a cell to a cytokine such as IL-4, IL-9 and/or interleukin-13. Methods using the compositions to treat disorders such as pulmonary disorders (e.g., asthma) also are provided.
