• Carboxymethyl chitosan for treatment of liver carcinomas

    Published on

    Hepatocellular carcinoma is a solid tumor that exhibits severe angiogenesis, cell cycle dysregulation, and evasion of apoptosis. Late diagnosis in a large proportion of patients is making the carcinomas inoperable, and various chemotherapeutic agents are used. Due to the numerous side effects of known chemotherapeutic agents, intensive research is performed on the use of natural products and their synthetic analogues. The authors of the presented study investigated the effect of carboxymethyl chitosan oligosaccharides on the growth of hepatocellular tumors in mice.

  • Chitosan and curcumin for treatment of glaucoma or cancer

    Published on

    Glaucoma is a group of diseases of the eye with damaged optic nerve and retina in advanced stages, possibly leading to blindness. One of the causes is increased intraocular pressure. Here, we present two publications, which investigated the combination of chitosan and curcumin for treatment of glaucoma and cancer patients.

  • Gold nanoparticles with chitosan

    Published on

    There are many potential applications of gold nanoparticles in medicine. Gold nanoparticles are already being used in diagnostics, as in pregnancy or HIV tests [1]. Research on the use as a contrast agent for the localization of cancer cells and as a drug delivery system for targeted release at site of action. The surface properties of gold are optimal for functionalization, e.g. with chitosan.

  • Drug delivery systems with chitosan

    Published on

    Biological barriers can limit the availability of a therapeutic agent in the target tissue. Drug delivery systems overcome these limitations to transport the correct dose of drug to its target site. The biopolymer chitosan has great potential for the development of innovative drug delivery systems. We present two articles that explore the treatment of cancer and noise-induced hearing loss with chitosan-based drug delivery systems.

  • Publications in July & August 2016 - drug delivery systems

    Published on

    Today´s topic is chitosan for drug delivery systems. In July and August 2016, 33 articles about chitosan combined with drug delivery systems were published. As might be expected, top publisher are China (13 articles), United States (5) and India (4). The articles investigated drug release by chitosan-based micro- or nanoparticles, hydrogels and nanocomposites. Thereby controlled release of cytostatics, proteins or peptides was mainly studied.
