CCBAR Q & A
Q: What is the reliability of DBS HbA1c measurement versus venous specimen analyzed under clinical conditions?
Studies showed that DBS collection method provides
accurate, robust, and reproducible measurement of Hb A(1c). Therefore,
dried blood spot samples represent an alternative to whole blood for
HbA1c by measurement when transporting whole blood is not feasible. The
specific assays used are not uniform and may differ from one lab to

epigenetics: Showing your age
by Darren J. Burgess
Characterizing the molecular features of ageing is key for
understanding the mechanisms of normal and premature ageing, and has
applications such as predicting the age of an individual from a
forensic sample. A new study has characterized the DNA methylomes of
large cohorts of humans
nature of confounding in genome-wide association studies
by Bjarni J. Vilhjįlmsson, Magnus Nordborg
The authors argue that population structure per se is not a problem in
genome-wide association studies ? the true sources are the environment
and the genetic background, and the latter is greatly underappreciated.
They conclude that mixed models effectively address this issue.

Autistic-like behaviors can be partially remedied by normalizing
excessive levels of protein synthesis in the brain, a team of

provide a pathway to the creation of pharmaceuticals aimed at treating
autism spectrum disorders (ASD) that are associated with diminished
social interaction skills, impaired communication ability, and

Earlier detection of autism, relying on markers in the blood, may help
more children to take advantage of helpful behavioral therapies.

agent briefly eases depression rapidly in test
A drug that works through the same brain mechanism as the fast-acting
antidepressant ketamine briefly improved treatment-resistant patients'

a clinical trial conducted by the National Institutes of Health. The
experimental agent, called AZD6765, acts through the brain's glutamate
chemical messenger system.
scientists uncover how immune cells sense who they are
Scientists at the National Institute of Arthritis and Musculoskeletal
and Skin Diseases (NIAMS), a part of the National Institutes of Health,
have demonstrated that DNA previously thought to be 'junk' plays a
critical role in immune system response. The team's findings were
published in Cell and may lead to the identification of new therapeutic
targets for the treatment of immune-related disorders.
proposes critical initiatives to sustain future of U.S. biomedical
The National Institutes of Health is seeking to launch multiple
initiatives designed to help strengthen the biomedical research
enterprise and sustain the global competitiveness of the U.S.
scientific community well into the future. Faced with significant
challenges affecting the biomedical research workforce and the storage
and use of large biomedical datasets, the NIH Director charged the
Advisory Committee to the Director (ACD) to develop recommendations.
The ACD used three specialized committee working groups, each of which
included additional outside experts on the relevant topics.
