Melanoma is a particularly deadly form of skin cancer very resistant to treatment. Researchers at H. Lee Moffitt Cancer Center & Research Institute and the University of South Florida are testing a promising new therapy that prompts the immune system to aid in the fight against melanoma tumors.
"This is a milestone clinical trial because it is the first time that electroporation is being used to deliver plasmid DNA in a gene therapy study in humans," said Richard Heller, PhD, USF professor of medical microbiology and immunology who helped develop the technology used in the study.
Electroporation is a technique in which a hand-held device applied to the skin delivers pulses of electricity to open up pores in the tumor cell membrane. This opening allows a small therapeutic molecule -- in this case a molecule known as a DNA plasmid that contains the gene for Interleukin-12 -- to slip inside the melanoma tumor before the membrane reseals.

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is...
At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
