New therapeutic options for newly diagnosed multiple myeloma patients

Mayo Clinic researchers presented results of a phase II trial of myeloma induction therapy -- a first step therapy designed to reduce cancer cells numbers -- with cyclophosphamide, bortezomib, and dexamethasone (Cybor-D) showing an improved response over the traditional lenalidomide-dexamethasone (L-Dex) therapy.

New role for miRNA in leukemia discovered

Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia (CML) from its more treatable chronic phase to a life-threatening phase, called blast crisis.

Safe and effective therapy discovered for patients with protein-losing enteropathy

Researchers at the Burnham Institute for Medical Research (Burnham Institute) have developed the first model to study intestinal protein leakage in mice, allowing the team to control and replicate both genetic deficiencies and environmental damages in an in vivo setting.

Depression nearly triples the risk of death following a heart attack

...even when accounting for other heart attack risk factors, according to research presented at the American College of Neuropsychopharmacology (ACNP) annual meeting, which showed that among 360 depressed, post myocardial infarction patients followed for more than six years, those who did not recover from their depression in the first six months were more than twice as likely to die.

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.
