Research published by the University of Helsinki, Finland, indicates that cytostatic and radiation therapies administered before stem cell transplantation often damage children’s permanent teeth.
Detrimental effects of cytostatic and radiation therapies on dental development have been known for a long time, but knowledge about the dental consequences of high-dose anticancer therapy preceding stem cell transplantation has so far been scarce. Päivi Hölttä, Licentiate in Dentistry, from the Institute of Dentistry, University of Helsinki, has studied the effects of high-dose anticancer chemotherapy and total body irradiation on the development of permanent teeth.
Tooth development is a genetically controlled chain of events that can be disturbed by various environmental factors. The development of permanent teeth begins as early as the 20th week of gestation and continues until the age of 14 to 15 years with the exception of wisdom teeth, which still continue their development for several years. All this time teeth are vulnerable to developmental aberrations.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
