Heritability of spinal pain and consequences of spinal pain: a comprehensive genetic epidemiologic analysis using a population-based sample of 15,328 twins ages 20-71 years.

13 Oct 2009 OBJECTIVE: To assess the relative contribution of genetic and environmental factors to different definitions of spinal pain and consequences of spinal pain. METHODS: The Danish Twin Registry contains detailed survey information on spinal pain and ... Read more...

Major depression and coronary flow reserve detected by positron emission tomography.

10 Oct 2009 BACKGROUND: Major depressive disorder (MDD) is associated with coronary heart disease (CHD), but the mechanisms are unclear. The presence of MDD may increase CHD risk by affecting microvascular circulation. It is also plausible that genetic factors ... Read more...

Characteristics and concordance of autism spectrum disorders among 277 twin pairs.

29 Sep 2009 OBJECTIVES: To examine patterns of autism spectrum disorder (ASD) inheritance and other features in twin pairs by zygosity, sex, and specific ASD diagnosis. DESIGN: Cross-sectional study. SETTING: Internet-based autism registry for US residents. ... Read more...
