In recent years, scientists have made important strides in developing drugs that help patients manage the symptoms of Parkinsons Disease – a chronic, progressive movement disorder affecting as many as one million Americans. But despite their effectiveness, the drugs dont stop Parkinsons disease from progressing, causing patients symptoms to eventually grow worse in spite of medication.
Now, researchers at Cedars-Sinai Medical Center have found that two specific proteins – "Sonic Hedgehog" and "Gli-1" – delivered via a genetically engineered virus into the brains of laboratory rats, prevented the progressive degeneration of nerve cells in the brain that cause Parkinsons disease. The study, published in the September issue of the journal, Molecular Therapy, may lead to a new way to treat patients with advanced Parkinsons Disease.
"Our results establish, for the first time, that viral transfer of Sonic hedgehog and Gli-1 - two proteins that are involved in early brain development, but are no longer present in the adult brain – may provide a new strategy to prevent progressive degeneration of the nerve cells in the brain that cause Parkinsons disease," said Pedro Lowenstein, M.D., Ph.D., Director of the Gene Therapeutics Research Institute at Cedars-Sinai Medical Center, and a Professor of Medicine and Pharmacology at UCLA.

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...
