'Nanospheres' that block pain of sensitive teeth
Nanospheres could help dentists fill the tiny holes in our teeth that make them incredibly sensitive, and that cause severe pain for millions of adults and children worldwide. Preliminary research presented today at the Institute of Physics conference EMAG-NANO 2005 shows that creating tiny spheres of a ceramic material called hydroxyapatite could be a long term solution or cure for sensi...Fatty spheres loaded with siRNA shrink ovarian cancer tumors in preclinical trial
A molecular "off" switch packaged in a tiny sphere penetrates deeply into ovarian cancer tumor cells, stifling a troublesome protein and drastically reducing the size of tumors, researchers at The University of Texas M. D. Anderson Cancer Center report in the Aug. 15 edition of Clinical Cancer Research. The mouse model experiment, featured on the cover of the journal, demonstrates a poten...Engineer ramps up protein production, develops versatile viral spheres
Scientists are taking the amazing protein-making parts out of cells and putting them into systems to mass-produce designer proteins for a wide variety of medical uses. At the annual meeting of the American Chemical Society (ACS) Sept. 13 in San Francisco, Stanford engineering Professor James Swartz will discuss advances in such "cell-free" protein synthesis, including production of versatile, nan...Penn researchers show how nanocylinders deliver medicine better than nanospheres
Researchers at the University of Pennsylvania School of Medicine & School of Engineering and Applied Science have discovered a better way to deliver drugs to tumors. By using a cylindrical-shaped carrier they were able sustain delivery of the anticancer drug paclitaxel to an animal model of lung cancer ten times longer than that delivered on spherical-shaped carriers. These findings have impl...Biodegradable microspheres deliver time release vaccines, stimulate different immune response
A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. Researchers from Iowa State University report their findings today at the ASM Biodefense and Emerging Disease Research Meeting. "Current vaccines are good at producing an...BlockAid blocking solution *for use with microspheres* from Molecular Probes (Invitrogen)
Description:Molecular Probes intensely fluorescent and highly photostable FluoSpheres microspheres have enormous potential for use in a variety of applications requiring probes that can deliver a strong signal. Unfortunately, protein- and other macromolecule-labeled microspheres have hydrophobic regions that may cause them to bind to non-target surfaces in some applications. This nonspecific binding can be r...Radiesse Calcium Hydroxylapatite (CaHA) Microspheres
Description:Radiesse brings you into the new age of non-surgical facial contouring materials. You can now offer your patients immediate, long-term results for various applications with exceptional safety and flexibility. This injectable filler offers superior versatility for a wide variety of non-surgical cosmetic and reconstructive treatments. Long-lasting, Radiesse saves time and money for both you and you...Artecoll Polymethylmethacrylate (PMMA) Microspheres
Description:Artecoll consists of homegeneous polymethylmethacrylate (PMMA) microspheres, evenly suspended in a solution of partly denatured 3.5% collagen. All microspheres are in a range of 32-40 microns in size, are completely round and have polymerized, smooth surfaces. 99.9% of the remaining monomers have been removed during the processing of the PMMA. Artecoll contains an average concentration of 0.3...
