  • Publication number: 20210353217
    Abstract: Devices and systems for characterizing a condition of spinal deformities are contemplated. Mobile devices that incorporate inclinometers or accelerometers (e.g., a smart phone) are held securely in a supporting structure that renders it useful to characterize spinal deformities such as scoliosis and/or kyphosis. Supporting structures can include features that secure the mobile device (for example, chamfered surfaces, high friction surfaces, pliant projections, straps, hook and loop enclosures, tensioning devices, detents, etc.) in an upper portion and a lower portion that includes at least one, but preferably two or more rollers, and an interposing centrally placed notch dimensioned to permit the assembled device (supporting structure and mobile device) to span the width of a typical human spinal column. At least one roller includes an encoder (e.g.

  • Publication number: 20210317500
    Abstract: Recombinant IL-11 is expressed in yeast, then isolated from aerobic fermentation media by precipitation, solubilization of the precipitate in the presence of a denaturant, and renaturation of the solubilized protein. Renatured rhIL-11 is further purified by cation exchange and hydrophobic interaction chromatography to provide a highly purified rhIL-11 with high biological activity and low rhIL-11 dimer and oxidized rhIL-11 content.

  • Patent number: 11123421
    Abstract: Compositions and methods are provided for a live, attenuated influenza vaccine suitable for nasal administration. The vaccine utilizes a cold adapted influenza virus that lacks virulence factor, and includes mutations that provide replicative ability sufficient for vaccine manufacture. Vaccines so produced provide significant cross protection for non-vaccinating strains. The vaccine is safe for children under the age of 2 and adults over 49 years of age. In addition, the cold adapted, virulence factor deleted influenza virus can be adapted to provide immunity to non-influenza pathogens.

  • Publication number: 20210268117
    Abstract: Methods are provided for producing a PEGylated interleukin 11 (IL-11) tby treating a recombinant IL-11 PEGylated with an equimolar to low molar excess of PEG carrying an amine-reactive group to achieve a highly pure monoconjugate preparation, which provides improved half-life in serum while having desirable therapeutic activity and presenting fewer side-effects. Most preferably, the IL-11 is an N-terminally truncated human or humanized IL-11 and has a 20 Kd or 40 Kd branched PEG moiety, Y- or comb-shaped in particular, coupled to the N-terminal amino group. Such compounds are characterized by substantially increased stability in serum and sustained biological activity while exhibiting significantly reduced plasma expansion.

  • Publication number: 20210189370
    Abstract: Compositions and methods for the preparation of high purity arginase and high efficiency preparation of monosubstituted polyethylene glycol conjugation of arginase are provided, as are methods for using arginase in combination with asparaginase to inhibit cancer cells. High purity arginase is provided by applying an initial high temperature precipitation step, followed by ion exchange to provide arginase at a purity of 90% or greater. Conjugation with either linear or branched polyethylene glycol is performed using a maleimide-derivatized polyethylene glycol at low molar excess relative to arginase and at reduced temperature. Such polyethylene glycol-derivatized arginase is useful in combination with asparaginase in inhibiting the growth of cancer cells, particularly cells that have low endogenous asparaginase expression.

  • Publication number: 20210156080
    Abstract: Compositions and methods are described that provide cellulosic and non-cellulosic fabrics with durable antimicrobial properties. Application of a coating that includes polyhexamethylene biguanide, polyethylene glycol, and a binder to a fabric followed by drying and curing was found to provide antimicrobial properties that are retained through over 100 washings under aggressive hospital washing conditions. In addition, tactile properties and tear resistance of the treated fabrics are maintained or improved.

  • Publication number: 20210030789
    Abstract: A preparation of silver nanoparticles has been found to be effective in improving functional and behavioral recovery from traumatic spinal cord injury. The silver nanoparticles are provided in a non-flowable gel vehicle, from which they are release at high efficiency, that is applied locally at the site of the spinal cord injury. Silver nanoparticle formulations described herein were found to modify the M1/M2 macrophage phenotype ratio and provides a synergistic effect in the combination with arginase to promote healing processes at the treated injury site, reducing postinjury inflammation.

  • Publication number: 20210023042
    Abstract: A pharmaceutical composition comprises a taxane (e.g., paclitaxel, docetaxel, cabazitaxel, larotaxel, ortataxel, and/or tesetaxel) in a mixture of first and second surfactants. The absorption of the taxane is increased from the pharmaceutical composition is greater than the sum of the absorption of docetaxel from either the first or the second surfactant. The increase in absorption is especially enhanced when the ratio of the first surfactant to the second surfactant in the pharmaceutical composition is between 60:40 and 85:15 by weight, and the total surfactant weight does not exceed 98% of the total weight. Polysorbate 80, polysorbate 20, and caprylocaproyl polyoxylglycerides serve as suitable first surfactants, and polysorbate 80 or polyethyoxylated castor oil serve as suitable second surfactants. The stability of the pharmaceutical composition may be enhanced by further including a stabilizer (e.g., citric acid and/or ascorbic acid).
