摘要:
Immunogenic influenza hemagglutinin-derived peptide conjugates described herein induce a specific therapeutic antibody response against influenza virus. The immunogenic peptide conjugates comprise a segment from the fusion initiation region (FIR) domain of an influenza hemagglutinin protein conjugated to an immunogenic carrier protein, such as keyhole limpet hemocyanin (KLH), bovine serum albumin (BSA), an influenza hemagglutinin (HA) protein (i.e., full length HA), and the like. The immunogenic peptide conjugates described herein can be utilized to treat or prevent influenza infection and to prepare influenza-specific therapeutic antibodies that interfere with influenza virus-host cell membrane fusion. The peptide conjugates can be formulated in pharmaceutical compositions useful for broad spectrum treatment or prevention of influenza infections.

摘要:
A method of monitoring the evolution of polymer and/or colloid stimuli responsiveness during synthesis of polymers and/or colloids, including postpolymerization modifications on natural and synthetic polymers, includes providing a reactor in which the polymers and/or colloids are synthesized; and providing a means of monitoring the stimuli responsiveness of the polymers and/or colloids during said synthesis. Preferably, the method also includes monitoring the evolution of the characteristics of the polymers and/or colloids during said synthesis. Preferably, evolution of polymer and/or colloid stimuli responsiveness is correlated to the evolution of the properties of the polymers and/or colloids themselves. Also, preferably the conditions of the fluid in the reactor in which the synthesis occurs is determined. The determination can be by detection, choice of materials and temperature conditions, for example, and combinations thereof. The method and instrumentation disclosed can lead to optimization and control of processes and synthetic and modification strategies leading to polymers and colloids with desired stimuli responsiveness.

The disclosure provides drug delivery devices and methods of making and using the drug delivery devices. The devices include single and multi-layer polymer films made by a breath figure technique having therapeutic agents associated therewith. For example, the devices may be a dual layer polymer film wherein the first layer includes a therapeutic agent incorporated into it by spin coating the first agent with a polymer solution and the second agent is incorporated into the second layer by loading the agent into pores of the second layer after it is spin coated onto the first layer. In some cases one layer provides a burst release and the second layer provides a slow release drug delivery profile. The devices may take on the form of a surgical mesh with a slow release therapeutic drug.
摘要:
Artificial microvascular network (AMVN) devices are provided and related methods of making and methods of using such devices are provided. The present disclosure generally relates to an AMVN device comprising a substrate including a capillary network configured so as to simulate those actually encountered in the circulation of various humans and animal model systems. In certain aspects, the AMVN devices may be used, e.g., to investigate the effect of storing RBCs under aerobic and anaerobic conditions. However, the use of such AMVN devices is not so limited.
摘要:
Otologic materials and methods are provided. For example, a cell-adhesive, biodegradable hydrogel scaffold loaded with time-released drugs for repairing chronic tympanic membrane perforations is disclosed, methods of making same and administering same are provided. This hydrogel may promote vascular in-growth and epithelial cell growth of the tympanic membrane with the purpose of closing the perforation and providing a barrier between the external and middle ear. The hydrogel is initially a liquid polymer that only gels upon exposure to specific conditions, such as exposure to light. This scaffold may simultaneously induce repair of the tympanic membrane while preventing or alleviating middle ear infection, thus filling a void in current tympanic membrane perforation therapies.
摘要:
Disclosed are methods of modulating the expression of genes linked to adipocytokine signaling, carbohydrate metabolism, fatty acid metabolism, arachidonic acid metabolism, PPAR signaling, insulin signaling, lipid metabolism, extracellular matrix (ECM)-receptor interaction, or combinations thereof, methods of treating hyperlipidemia, obesity, excessive cholesterol, cardiovascular disease, liver disease, diabetes, or combinations thereof, and methods of stimulating glucose uptake in an animal in need thereof, comprising administering a composition comprising at least one isolated glyceollin to said animal.
摘要:
A method of treating contaminated air, gas and surfaces is accomplished through the nebulization of gas and/or liquid oxidants through a field of electromagnetic radiation or sonic waves. The contaminated gas and/or liquid streams are blended with gaseous and/or liquid oxidants by the nebulizer and directly injected in the energy field. Free radicals produced from oxidants in the presence of the energy field instantaneously oxidize a large effective surface area of the contaminated media. Surfaces are treated more efficiently with the energy field situated directly above and parallel to but not on the surface; a high-frequency energy field may be used to create a large concentration of free radicals without damaging the surface in a collimated beam of the field situated parallel to the surface. A catalyst may be employed at the tip (i.e. discharge orifices of gas and/or liquid) of the nebulizer or blended into the nebulized cloud to increase the formation of free radicals. The method may also be used to carry out a reduction instead of an oxidation reaction.
摘要:
This invention relates to novel analogs of pituitary adenylate cyclase-activating polypeptide (PACAP), which are agonists for the PACAP/vasoactive intestinal peptide (VIP) receptors: PAC1, VPAC1 and VPAC2 receptors. These PACAP analogs can be used as prophylactic/therapeutic agents for a wide range of medical disorders, including (but not limited to) cancer and autoimmune disease. These PACAP analogs can be coupled to suitable radionuclides and used in the localization, diagnosis and treatment of disseminated cancers and metastatic tumors, or coupled to small molecule therapeutics and used as vectors for targeted drug delivery. This invention also provides pharmaceutical compositions of one or more PACAP-like compounds of the invention either alone or in combination with one or more other prophylactic/therapeutic agents.
