A multicenter international study, including Johns Hopkins, has found that after surgery for thyroid cancer, giving genetically engineered human thyroid-stimulating hormone (rhTSH) before radioiodine treatment avoids the previous need to stop thyroid replacement therapy and the miserable side effects that go with it.
The study, led by Paul Ladenson, M.D., director of the Division of Endocrinology at The Johns Hopkins University School of Medicine, and Furio Pacini at the University of Siena in Italy, was reported in the December online edition of the Journal of Clinical Endocrinology and Metabolism.
Typically, radioiodine treatment for cancer of the thyroid gland requires temporary discontinuation of thyroid hormone replacement for several weeks, leading to weight gain, constipation, fatigue, slowed thinking, depressed mood, muscle cramps, intolerance of cold temperatures and other symptoms. "This study shows that patients who use a recombinant form of TSH can continue their thyroid replacement therapy and enjoy a better quality of life during their cancer treatment," Ladenson says.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
