A team of scientists from the University of California, San Diego School of Medicine, the Medical University of South Carolina and San Diego-based American Life Science Pharmaceuticals, Inc., report that cathepsin B gene knockout or its reduction by an enzyme inhibitor blocks creation of key neurotoxic pGlu-Aβ peptides linked to Alzheimer's disease (AD). Moreover, the candidate inhibitor drug has been shown to be safe in humans.

Experts across academia, industry and government propose a new method for health care providers to get the right treatments to the right patients at the right time. This new approach, A Proposal for Integrated Efficacy-to-Effectiveness (E2E) Clinical Trials, published in Nature Clinical Pharmacology & Therapeutics, recommends a seamless transition from controlled experiments to real-world comparative effectiveness trials.

The Institute for Research in Immunology and Cancer (IRIC) at the Université de Montréal (UdeM), in collaboration with the Maisonneuve-Rosemont Hospital's Quebec Leukemia Cell Bank, recently achieved a significant breakthrough thanks to the laboratory growth of leukemic stem cells, which will speed up the development of new cancer drugs.

Honey, that delectable condiment for breads and fruits, could be one sweet solution to the serious, ever-growing problem of bacterial resistance to antibiotics, researchers said. Medical professionals sometimes use honey successfully as a topical dressing, but it could play a larger role in fighting infections, the researchers predicted. Their study was part of the 247th National Meeting of the American Chemical Society (ACS), the world's largest scientific society.

Scientists at The Scripps Research Institute (TSRI) have developed a method for modifying organic molecules that significantly expands the possibilities for developing new pharmaceuticals and improving old ones. The innovation makes it easier to modify existing organic compounds by attaching biologically active "functional group" to drug molecules.

During a one year period, among clinical trials published in high-impact journals that reported results on a public clinical trial registry (ClinicalTrials.gov), nearly all had at least 1 discrepancy in the study group, intervention, or results reported between the 2 sources, including discrepancies in the designated primary end points for the studies, according to a study in the March 12 issue of JAMA.

Melbourne scientists are a step closer to creating a new drug to stop a heart attack in its tracks and reduce the damage caused, without any side effects. The Monash University research, published today in the journal, Proceedings of the National Academy of Sciences, USA (PNAS), offers new hope to thousands of people who experience heart attacks and heart failure - one of the major causes of death worldwide.
