  • Publication number: 20190239797
    Abstract: Devices, systems and methods 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.

  • Patent number: 10335398
    Abstract: Sprayable aqueous pharmaceutical compositions containing granisetron or a pharmaceutically salt thereof, and pharmaceutically acceptable inactive ingredients, including tonicity agents, preservatives, and water soluble polymers with bioadhesive properties and/or capable of changing the rheological behavior in relation to ions, pH and temperature. The compositions are intranasally administered to a subject in need thereof in the rapid management and or prevention of nausea and/or vomiting induced by cytotoxic chemotherapy, radiation, or surgery. The composition has the advantages of rapid absorption and onset of action, prolonged drug plasma concentration and pharmacological effects comparable to intravenous infusion, as well as reduced nasal stinging sensation.

  • Patent number: 10335492
    Abstract: Compositions and methods are presented in which recombinant IL-11 is PEGylated to achieve improved half-life in serum while having desirable therapeutic activity and presenting less 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: 20190125858
    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: 20190054060
    Abstract: Therapy for influenza using a combination of a neuraminidase inhibitor, a macrolide antibiotic, and a non-steroidal anti-inflammatory drug has been found to provide improved clinical outcomes and reduced incidence of viral quasispecies compared to conventional treatment with neuraminidase inhibitors alone. Effective treatment schedules are also provided. The drug combination can be used in concert with a proton-pump inhibitor and/or an additional antibacterial antibiotic.

  • Publication number: 20180207149
    Abstract: Compositions and methods are described in which the topical application of a toll-like receptor 7 agonist or a toll-like receptor 9 agonist at or near a subdermal vaccination site provides an enhanced response to the vaccination. The enhanced response can be an elevated antibody titer relative to an untreated but vaccinated subject, and/or development of cross-species immunity to species not present in the vaccinating composition.

  • Publication number: 20180127836
    Abstract: Highly conserved, short untranslated leader sequences have been identified in MERS-CoV and other human pathogenic Coronaviruses that provide the basis for highly sensitive and accurate assays for these viruses. Use of locked nucleic acids is shown to be useful in amplification reactions for these short sequences. RT-PCR using locked nucleic acids is shown to provide accurate detection of a variety of human pathogen Coronaviruses present at 10 copies per reaction or less.

  • Publication number: 20170224613
    Abstract: Disclosed are hydrogel composition, method for preparing the same and use thereof. The hydrogel composition comprises a guar gum derivative which is crosslinked, a mint-based component, water, and optionally, an amphiphilic core-shell nanoparticle having a hydrophobic core and a hydrophilic shell, wherein the amount of the mint-based component is in the range of 1-6 wt % and the amount of the water is in the range of 65-95 wt %, based on the total weight of the hydrogel composition. The hydrogel composition is safe and can provide symptomatic relief for patients with symptoms such as severe and intractable pruritus associated with hypertrophic scars. The symptomatic relief effect of the hydrogel composition is reproducible, and is independent of the etiology of the burn trauma, extent of the scarring and duration of the scar formation, while tachyphylaxis is not observed. Also disclosed is a medical device comprising the hydrogel composition.

  • Publication number: 20170087121
    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).
