The current study examined the factor structure of restricted and repetitive behaviors (RRB) in children with autism. Factor extraction procedures of 12 items from the Autism Diagnostic Interview-Revised (ADI-R) were applied in N = 207 individuals with autism. Two interpretable factors were identified: Factor 1--repetitive sensory motor actions and Factor(More)
Four genes affecting Alzheimer's Disease (AD)(AP, PS1, PS2, and APOE) have been identified and a fifth potential gene localized to chromosome 12. Collectively, these genes explain at most half of the genetic effect in AD. Understanding the genetics of AD is critical to developing new treatments. The quest to find the remaining AD genes led us to undertake a(More)
The mouse short ear gene is required for normal growth and patterning of skeletal structures, and for repair of bone fractures in adults. We have carried out an extensive chromosome walk in the chromosome region that surrounds this locus. Here we show that the short ear region contains the gene for a TGF beta-related protein called bone morphogenetic(More)
Butyrylcholinesterase (BCHE) is an enzyme expressed in most human tissues. Recently, an increased odds of carrying the K variant of BCHE (BCHE-K) was reported among Alzheimer disease (AD) cases as compared with controls. We tested our data set of 245 sporadic AD cases and 241 controls for an association between BCHE-K, APOE4, and AD using logistic(More)
BACKGROUND We describe the study design, procedures, and development of the risk counseling protocol used in a randomized controlled trial to evaluate the impact of genetic testing for diabetes mellitus (DM) on psychological, health behavior, and clinical outcomes. METHODS/DESIGN Eligible patients are aged 21 to 65 years with body mass index (BMI) ≥27(More)
OBJECTIVE A weight loss maintenance trial involving weight loss prior to randomization is challenging to implement due to the potential for dropout and insufficient weight loss. We examined rates and correlates of non-initiation, dropout, and insufficient weight loss during a weight loss maintenance trial. METHODS The MAINTAIN trial involved a 16-week(More)

Interventions to improve glycemic control reduce the progression of diabetic retinopathy. 1 Additionally, pharmacologic reduction of blood pressure (BP) in patients with(More)
