Computed tomography (CT)-guided injections offer a safe delivery method for gene therapy in patients with metastatic kidney cancer, according to a study in the May issue of the journal Radiology.
Gene therapy involves introducing genetic material directly into cells to fight disease. "The new gene therapies offer promise for controlling certain types of cancer, but delivering the agents directly into tumors poses its own set of challenges," said the studys lead author, Robert D. Suh, M.D., who is an assistant clinical professor of radiology and director of thoracic interventional services at the David Geffen School of Medicine at University of California, Los Angeles (UCLA). "As research in gene therapy, or immunotherapy, progresses, we need a good gene therapy delivery mechanism."
Treatment of metastatic kidney cancer is difficult because the disease is largely resistant to chemotherapy. The only Food and Drug Administration (FDA)-approved immunotherapeutic treatment, recombinant interleukin-2 (IL-2), has a response rate of only 15 percent when administered intravenously, and its use is limited by significant and occasionally life-threatening side effects. Researchers have developed several gene therapy agents to improve the effectiveness and minimize the side effects of IL-2. UCLAs technique involves injecting an IL-2-encoded recombinant gene directly into cancer cells.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
