  • Patent number: 11191721
    Abstract: Disclosed herein is a particle delivery system comprising electrospun nanofiber comprised of coaxial fiber with a microfluidic core. Iron-doped apatite nanoparticles (IDANPs) have demonstrated a unique influence over phage killing of bacteria, whereby, IDANP-exposed bacterial cultures experience 2× the bacterial death as controls. IDANPs consist of hydroxyapatite (HA) doped with iron. HA is a mineral known to be biocompatible and analogous to the inorganic constituent of mammalian bone and teeth and has been approved by the Food and Drug Administration (FDA) for many applications in medicine and dentistry. Previous work has shown that for IDANPs to enhance antibacterial activity of phage to the greatest extent, bacterial cultures should be exposed to IDANPs for 1 hr prior to phage introduction. Biocompatible polymer materials which encase IDANPs and/or phage can be used to disseminate IDANPs and/or phage in a controlled manner into a physiological system for treatment of bacterial infection.

    Abstract: The present invention relates to a method for the rapid evaluation of bacterial susceptibility or non-susceptibility of bacteria to antibiotics that inhibit protein synthesis. The rationale is to identify bacterial responses that depend or are influenced by protein synthesis. If this response is prevented or reduced by the antibiotic that inhibits the protein synthesis, the bacteria are susceptible to this antibiotic. Otherwise, if the response keeps similar despite the incubation with the antibiotic, the bacteria are not susceptible or resistant to this antibiotic. These responses could be determined at the DNA lev-el, cell wall level, morphological level or any other experimental approach, including metabolic, bio-chemical, physiological or genetic processes.

  • Patent number: 9649330
    Abstract: A wound care dressing that combines a sodium alginate hydrogel spread and a calcium solution spray to create a transparent membrane over damaged skin eliminating the need for a secondary dressing. The calcium dissolved in alcohol displaces sodium from the hydrogel spread, resulting in the formation of the membrane. The membrane decreases healing time by fostering hemostasis, a moist wound healing environment and absorption of exudate and blood from the wound. The membrane also provides an immediate cooling effect for the damaged skin. Once the wound is cleaned, the user applies the hydrogel and covers it with a mist of spray which creates a film layer. The membrane is transparent and flexible such that the skin surface is still visible and the membrane will not be dislodged as the skin is manipulated. The dried surface of the membrane is not tacky, eliminating the need for a secondary dressing.

  • Publication number: 20140228452
    Abstract: Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.

  • Publication number: 20140199705
    Abstract: The invention relates to polypeptides having glucanase, e.g., endoglucanase, mannanase, xylanase activity or a combination of these activities, and polynucleotides encoding them. In one aspect, the glucanase activity is an endoglucanase activity (e.g., endo-1,4-beta-D-glucan 4-glucano hydrolase activity) and comprises hydrolysis of 1,4-beta-D-glycosidic linkages in cellulose, cellulose derivatives (e.g., carboxy methyl cellulose and hydroxy ethyl cellulose) lichenin, beta-1,4 bonds in mixed beta-1,3 glucans, such as cereal beta-D-glucans or xyloglucans and other plant material containing cellulosic parts. In addition, methods of designing new enzymes and methods of use thereof are also provided. In alternative aspects, the new glucanases e.g., endoglucanases, mannanases, xylanases have increased activity and stability at increased pH and temperature.

  • Patent number: 8771720
    Abstract: Polyhydroxyalkanoates (PHAs) from which pyrogen has been removed are provided. PHAs which have been chemically modified to enhance physical and/or chemical properties, for targeting or to modify biodegradability or clearance by the reticuloendothelial system (RES), are described. Methods for depyrogenating PHA polymers prepared by bacterial fermentation processes are also provided, wherein pyrogens are removed from the polymers without adversely impacting the polymers' inherent chemical structures and physical properties. PHAs with advantageous processing characteristics, including low melting points and/or solubility in non-toxic solvents, are also described. The PHAs are suitable for use in in vivo applications such as in tissue coatings, stents, sutures, tubing, bone, other prostheses, bone or tissue cements, tissue regeneration devices, wound dressings, drug delivery, and for diagnostic and prophylactic uses.

  • Patent number: 8753856
    Abstract: The present invention provides a stable and viable biocatalyst with high activity and operational stability and method of immobilization thereof. The immobilization process is based on the principle of entrapment of partially purified enzyme precipitate which is simultaneously aggregated by cross linking agent like glutaraldehyde and further entrapped in a combination of natural polymer like gelatin and synthetic polymer like polyvinyl alcohol with effective gelation under mild conditions of temperature and pH, resulting in a stable biocatalyst. The enzymes immobilized by the above process include Penicillin acylase from rE. coli RE III (pKA18), Novel Penicillin acylase from Achromobacter sp (CCM4834) expressed in rE. coli BL21 (pK1P1) CCM 7394 and rE. coli RE III (pKX1P1).

  • Publication number: 20140147885
    Abstract: Semi-permeable particle can be used to facilitate chemical reactions such as catalytic reactions. The semi-permeable particles are permeable to molecules having a molar mass of 1000 Daltons or less and have a mode particle size of at least 1 ?m. The semi-permeable particles have multiple discrete cavities containing an aqueous solution or suspension of an organic catalytic material. The semi-permeable particles are also impermeable to the organic catalytic materials so they are retained within the multiple discrete cavities, and the semi-permeable particles can be reused multiple times for the same or different chemical reaction.
