Differentiated thyroid cancer, the most common form of thyroid cancer, is one of the success stories in the war on cancer. Since the advent of radioiodine therapy, it has been considered one of the most curable cancers. On the downside, current treatment involves taking patients off their thyroid medication. This can lead to serious side effects including symptoms of hypothyroidism, an unbalanced metabolic state that can induce fatigue, depression, and other unpleasant conditions.
Bart de Keizer, MD, and a team from the University Medical Center in Utrecht, The Netherlands, and Ghent University Hospital, Belgium, reported in the September issue of The Journal of Nuclear Medicine, on a new technique that allows patients to maintain their normal course of thyroid medication prior to and during radioiodine therapy. The new technique avoids the problems of hypothyroidism, and levels of radiation in the blood and bone marrow remain well below the accepted safety thresholds during therapy.
Currently, thyroid cancer patients who have had their thyroid removed are treated with radioactive iodine, which effectively zeros in on and kills any remaining cancerous thyroid cells. But prior to radioiodine treatment, the patient must be taken off thyroid hormone replacement medication for up to 6 weeks. The withdrawal of thyroid medication signals the body to produce thyroid stimulating hormone (THS). TSH causes any remaining or metastasized thyroid cells to quickly absorb the radioactive iodine when it is administered, in effect forcing the cancerous cells to absorb lethal radioactive molecules that are largely ignored by other cells in the body.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
