Seeking to find a way to lessen patients’ vulnerability to deadly infections following chemotherapy, researchers at the Stanford University School of Medicine have figured out a way to boost the immune function in animals following such treatments. Their approach involves increasing the pool of cells that give rise to neutrophils, a type of white blood cell that is critical for fighting bacterial and fungal infections but is particularly ravaged by chemotherapy.
"Our approach hadn’t been studied before, which is interesting because it’s a very straightforward concept," said study leader Janice "Wes" Brown, MD, assistant professor of medicine in the divisions of bone marrow transplantation and infectious diseases.
The team reported that an infusion of a type of bone marrow cell from a donor mouse yielded significantly more neutrophils in the laboratory mice a week after a dose of a typical chemotherapeutic agent. The procedure also increased the animals’ ability to fight a deadly fungal infection. The team’s findings appear in the Dec. 15 issue of the journal Blood.

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...
