Heads Up June 8 | Proteins assembling, stem cells from cadavers, and sponges that help muscles PDF Print E-mail

Untangling how proteins assemble  
Nature Structural and Molecular Biology
Université de Montreal researchers have been able to visualize how proteins assemble by integrating fluorescing molecules into the process. Understanding the different step on protein folding and assembly, many of which take place in very short (and hard-to-see) periods of time, will help better understand assembly, misfolding, and perhaps help bioengineers develop new ways to assemble molecules.

Reconstructive surgery for FGM can help ease pain, restore pleasure
The Lancet
A study in the Lancet of long-term outcomes of reconstructive surgery after female genital mutilation (FGM) finds that most experienced a lessening of pain and an increase in pleasure after the surgery, and the authors (one of whom pioneered the surgery) suggest it be made more widely available to women who have experienced FGM.

 Children and mental health visits to emergency in Alberta
A study of over 20,000 children in Alberta who visited emergency rooms for mental health issues found that First Nations children and those who received government assistance had more return visits than other children.

Sponge doesn’t let muscles get spongy
Nature Communications
Canadians at McGill have found that pateamine A, a chemical derived from marine sponges, are able to prevent muscle wasting in mice.

Cadavers can yield stem cells up to 17 days after death
Nature Communications
Skeletal muscle stem cells can be isolated from a human up to 17 days after death, a study finds. This greatly extends the time frame for how long after death stem cells can be taken from a  cadaver, and makes them a new potential source of these cells.

In Case You Missed...

The SMCC sent out Experts Comments this week on the Lancet paper “Radiation exposure from CT scans in childhood and subsequent risk of leukaemia and brain tumours: a retrospective cohort study”. The comments have been updated on our website along with some background information on CT scans and cancer risk.


The 2012 Goldschmidt conference will take place in Montreal from June 24-29. The Earth sciences conference will attract over 3,000 delegates. For more information go to http://www.vmgoldschmidt.org/2012/index.htm

The United Nations Conference on Sustainable Development takes place from June 20-22 in Brazil. For more information see http://www.uncsd2012.org/rio20/index.html. The SMCC will be sending out more information about this event and Canadian research on sustainability as the event approaches.
