BACKGROUND Despite strong circumstantial evidence that the pathophysiology of Gilles de la Tourette syndrome (TS) involves structural and functional disturbances of the basal ganglia, inconsistent findings from relatively small in vivo TS imaging studies have supported contradictory conclusions concerning the role of abnormal anatomical characteristics of(More)
BACKGROUND The dearth of long-term follow-up studies of community-based samples and differences in methodology in existing studies highlight the need for research designed to examine the stability, comorbidity, and diagnostic thresholds of depression and anxiety in the community. METHODS Prospective study of a community-based cohort aged 19 and 20 years(More)
One-carbon metabolism facilitates the crosstalk between genetic and epigenetic processes and plays critical roles in both DNA methylation and DNA synthesis, making it a good candidate for studying the risk of breast cancer. We previously reported that polymorphisms in methylenetetrahydrofolate reductase (MTHFR) in one-carbon pathway were associated with(More)
AIMS This paper (1) examines the validity of the atypical subtype of depression in a community-based longitudinal cohort study, (2) presents estimates of the prevalence and sex differences of DSM-IV atypical depression and a newly more broadly defined atypical syndrome in the community and (3) compares the clinical correlates and treatment patterns of those(More)
AIMS To investigate the association between socioeconomic status (SES) and incidence of diabetes. METHODS We investigated three measures of SES and incidence of diagnosed diabetes among women and men in the NHANES I Epidemiologic Followup Study, 1971-1992, who were free of diagnosed diabetes in 1980. RESULTS Among women, diabetes incidence was inversely(More)
Precise classification of tumors is critically important for cancer diagnosis and treatment. It is also a scientifically challenging task. Recently, efforts have been made to use gene expression profiles to improve the precision of classification, with limited success. Using a published data set for purposes of comparison, we introduce a methodology based(More)
Premature human infants frequently suffer from periventricular leukomalacia (PVL) characterized by the loss of central myelinated tracts in the brain [Neuropathology, 22 (2002) 193]. Rodent chronic sublethal hypoxia (CSH) from P3 to 33 (postnatal day 3-33) provides a model for PVL characterized by cerebral ventriculomegaly and reductions in cerebral white(More)
BACKGROUND The goals of the present study are to describe the prevalence, risk factors, course, and impact of social phobia in a 15-year prospective longitudinal community study; and to examine an expanded conceptualization of social phobia with respect to clinical indicators of severity, as well as gender differences, personality traits, and stability over(More)
Islet cell replacement is considered as the optimal treatment for type I diabetes. However, the availability of human pancreatic islets for transplantation is limited. Here, we show that human bone marrow-derived mesenchymal stem cells (hMSCs) could be induced to differentiate into functional insulin-producing cells by introduction of the pancreatic(More)
