A new prostate cancer "homing device" for drug delivery

A new prostate cancer "homing device" could improve detection and allow for the first targeted treatment of the disease. A team of Purdue University researchers has synthesized a molecule that finds and penetrates prostate cancer cells and has created imaging agents and therapeutic drugs that can link to the molecule and be carried with it as cargo.

Potential new target for acute myeloid leukemia

Dr. John Dick, Senior Scientist at the Ontario Cancer Institute, the research arm of Princess Margaret Hospital, co-led a multinational team that has developed the first leukemia therapy that targets a protein, CD123, on the surface of cancer stem cells that drive acute myeloid leukemia (AML), which is an aggressive disease with a poor outcome.

The surprising effect of cannabis on morphine dependence

Injections of THC, the active principle of cannabis, eliminate dependence on opiates (morphine, heroin) in rats deprived of their mothers at birth. This has been shown by a study carried out by Valérie Daugé and her team at the Laboratory for Physiopathology of Diseases of the Central Nervous System (UPMC / CNRS / INSERM) in the journal Neuropsychopharmacology. The findings could lead to therapeutic alternatives to existing substitution treatments.

Magnetic brain stimulation improves skill learning

The use of magnetic pulses to stimulate the dorsal premotor cortex (PMd) region of the brain results in an improved ability to learn a skilled motor task. Researchers writing in the open access journal BMC Neuroscience show that skilled movements can be stored as memories in the PMd and that magnetic stimulation of this area can facilitate this learning process.
