Slow-release ‘jelly’ delivers drugs better

Slow-release ‘jelly’ delivers drugs better

Jan. 28, 2013 — Duke University biomedical engineers have developed a new delivery system that overcomes the shortcomings of a promising class of peptide drugs — very small proteins — for treating diseases such as diabetes and cancer. There are more than 40 peptide drugs approved for use in humans and more than 650 are being tested in clinical studies. Continue reading

Modifications of a nanoparticle can change chemical interactions with cell membranes

Jan. 23, 2013 — Researchers at Syracuse University’s Department of Biomedical and Chemical Engineering at L.C. Smith College of Engineering and Computer Science are studying the toxicity of commonly used nanoparticles, particles up to one million times smaller than a millimeter that could potentially penetrate and damage cell membranes Continue reading

Linchpin of skin response to UVA light discovered

Jan. 21, 2013 — Researchers have strengthened their understanding of how skin cells called melanocytes sense ultraviolet light and act to protect themselves with melanin. In a new study, they report experiments showing that an ion channel well-known elsewhere in the body for its chemical sensitivity, plays a central role in this process Continue reading

3-D mapping of lipid orientation in biological tissues such as skin

Jan. 15, 2013 — A non-invasive method that makes it possible to observe in situ how assemblies of lipids are oriented in biological tissues, and which does not require any labeling or preparation, has been developed by physicists from the Laboratoire d’Optique et Biosciences (CNRS / Inserm / École Polytechnique).

3-D mapping of lipid orientation in biological tissues such as skin

Jan. 15, 2013 — A non-invasive method that makes it possible to observe in situ how assemblies of lipids are oriented in biological tissues, and which does not require any labeling or preparation, has been developed by physicists from the Laboratoire d’Optique et Biosciences (CNRS / Inserm / École Polytechnique). This work, published on the 14 January 2013 in the online journal Physical Review X , should enable the detection and characterization of certain pathologies associated with molecular disorders in the skin or in the nervous tissue.
