Ibuprofen better choice to relieve fracture pain in children than oral morphine
Although ibuprofen and oral morphine both provide effective pain relief for children with broken limbs, ibuprofen is the recommended choice because of adverse events associated with oral morphine, according to a randomized trial published in CMAJ.

How Staph infections elude the immune system
By tricking the immune system into generating antibodies specific for only one bacterial protein, Staphylococcus aureus dodges the production of antibodies that might otherwise protect against infection. The data suggest that future vaccine approaches must be designed to side-step this bacterial subterfuge.

It's better for memory to make mistakes while learning
Making mistakes while learning can benefit memory and lead to the correct answer, but only if the guesses are close-but-no-cigar, according to new research findings from Baycrest Health Sciences.

Discovery of how newborn mice repair bone fractures could improve treatments
Severe fractures in infants can heal on their own through a process that has eluded scientists. A study published in Developmental Cell reveals that a fractured arm bone in newborn mice can rapidly realign through a previously unknown mechanism involving bone growth and muscle contraction. The findings provide new insights into how human infants and other young vertebrates may repair broken bones and pave the way for more effective treatment strategies.

Breakthrough in molecular electronics paves the way for DNA-based computer circuits in the future
An international group of scientists reports reproducible and quantitative measurements of electricity flow through long molecules made of four DNA strands. These findings signal the most significant breakthrough towards the development of DNA-based electrical circuits in the last decade, paving an original way towards a new generation of computer circuits that can be more sophisticated, cheaper and simpler to make.

International research group publishes updated criteria for diagnosing multiple myeloma
The International Myeloma Working Group today announced that it has updated the criteria for diagnosing multiple myeloma. A paper outlining the new criteria was published in the journal Lancet Oncology. Multiple myeloma is a blood cancer that forms in a type of white blood cell called a plasma cell.

A key to aortic valve disease prevention: Lowering cholesterol early
An international research team led by the Research Institute of the McGill University Health Centre (RI-MUHC) and Lund University has provided new evidence that aortic valve disease may be preventable. Their findings show that so-called 'bad' cholesterol or low-density lipoprotein-cholesterol (LDL-C) is a cause of aortic valve disease -- a serious heart condition that affects around five million people in North America and is the most common cause for valve replacement.

Team discovers how microbes build a powerful antibiotic
Researchers report in the journal Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.

New nanodevice to improve cancer treatment monitoring
In less than a minute, a miniature device developed at the University of Montreal can measure a patient's blood for methotrexate, a commonly used but potentially toxic cancer drug. Just as accurate and ten times less expensive than equipment currently used in hospitals.

Activity in dendrites is critical in memory formation
Northwestern University researchers have discovered how neurons in the brain might allow some experiences to be remembered while others are forgotten. Using a unique microscope, they peered into the brain of a living animal navigating a virtual reality maze. Images of individual neurons called place cells showed that, surprisingly, the activity of the cell body and its dendrites can be different. A lasting memory of an experience was not formed by neurons when cell bodies were activated but dendrites were not.

Unsuspected gene found frequently mutated in colorectal, endometrial cancers
Scientists say they have identified in about 20 percent of colorectal and endometrial cancers a genetic mutation that had been overlooked in recent large, comprehensive gene searches. With this discovery, the altered gene, called RNF43, now ranks as one of the most common mutations in the two cancer types.

Genetic predisposition to elevated LDL-C associated with narrowing of the aortic valve
In an analysis that included approximately 35,000 participants, genetic predisposition to elevated low-density lipoprotein cholesterol was associated with aortic valve calcium and narrowing of the aortic valve, findings that support a causal association between low-density lipoprotein cholesterol and aortic valve disease, according to a study appearing in JAMA. The study is being released to coincide with its presentation at the Canadian Cardiovascular Congress.

Real-time readout of neurochemical activity

Right place, right time: Cellular transportation compartments
Proteins are the machinery that accomplishes almost every task in every cell in every living organism. The instructions for how to build each protein are written into a cell's DNA. But once the proteins are constructed, they must be shipped off to the proper place to perform their jobs. New work describes a potentially new pathway for targeting newly manufactured proteins to the correct location.
