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.

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
Working group led by physicist Professor Ulrich Nowak at the University of Konstanz, in collaboration with a team of physicists from Johannes Gutenberg University Mainz, demonstrates how skyrmions can be used for the computer concepts of the future
When it comes to performing a calculation destined to arrive at an exact result, humans are hopelessly inferior to the computer. In other areas, humans are...
