Medical researchers often presented the findings of their clinical trials in a different way on a federal government website than they did in the medical journals where their studies were ultimately published, according to an Oregon Health & Science University analysis published April 1 in the Annals of Internal Medicine.

Researchers from the University of California, San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences, in collaboration with materials scientists, engineers and neurobiologists, have discovered a new mechanism for using light to activate drug-delivering nanoparticles and other targeted therapeutic substances inside the body.

Application of U.S. and European cholesterol guidelines to a European population found that proportions of individuals eligible for statins differed substantially, with one U.S. guideline recommending statins for nearly all men and two-thirds of women, proportions exceeding those of the other guidelines, according to a JAMA study released online to coincide with the 2014 American College of Cardiology Scientific Sessions.

A large international consortium of researchers has produced the first comprehensive, detailed map of the way genes work across the major cells and tissues of the human body. The findings describe the complex networks that govern gene activity, and the new information could play a crucial role in identifying the genes involved with disease.

Plans for a new type of DNA vaccine to protect against the deadly HIV and Hepatitis C viruses have taken an important step forward, with University of Adelaide researchers applying for a patent based on groundbreaking new research. Professor Eric Gowans from the University's Discipline of Surgery, based at the Basil Hetzel Institute at the Queen Elizabeth Hospital, has submitted a patent application for what he describes as a relatively simple but effective technique to stimulate the body's immune system response, thereby helping to deliver the vaccine.

This alternative approach to creating artificial organic molecules, called bioretrosynthesis, was first proposed four years ago by Brian Bachmann, associate professor of chemistry at Vanderbilt University. Now Bachmann and a team of collaborators report that they have succeeded in using the method to produce the HIV drug didanosine. The proof of concept experiment is described in a paper published online March 23 by the journal Nature Chemical Biology.

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.
