In mice, genetically engineered knockout of the Dapper Antagonist of Catenin-1 (Dact1) locus, which encodes a scaffold protein involved in Wnt signaling, leads to decreased excitatory input formation on dendrites of developing forebrain neurons. We have previously demonstrated this in both (excitatory, glutamatergic) pyramidal neurons of the hippocampus and in (inhibitory GABAergic) interneurons of the cortex.

Traumatic brain injury and young onset dementia: a nationwide cohort study.

Little is known about the needs or characteristics of transgender individuals in substance abuse treatment settings. Transgender (n=199) and non-transgender (cisgender, n=13,440) individuals were compared on psychosocial factors related to treatment, health risk behaviors, medical and mental health status and utilization, and substance use behaviors within a database that documented individuals entering substance abuse treatment in San Francisco, CA from 2007 to 2009 using logistic and linear regression analyses (run separately by identified gender).

Recent characterizations of the transcriptome of the developing human brain by several groups have generated comprehensive datasets on coding and noncoding RNAs that will be instrumental for illuminating the underlying biology of complex neurodevelopmental disorders. This review summarizes recent studies successfully utilizing these data to increase our understanding of the molecular mechanisms of pathogenesis.

Population-based studies have reported high rates of smoking prevalence among Chinese and Vietnamese American men. Although nicotine replacement therapy (NRT) is effective, recommended, and accessible without prescription, these populations underuse NRT for smoking cessation. The aim of this study was to assess understanding and use of NRT and nonpharmacologic treatments among Chinese and Vietnamese American male smokers and their families.

This study was conducted to determine the relationship of frontal lobe cortical thickness and basal ganglia volumes to measures of cognition in adults with sickle cell anemia (SCA).

Genetic factors contribute to risk for bipolar disorder (BP), but its pathogenesis remains poorly understood. A focus on measuring multisystem quantitative traits that may be components of BP psychopathology may enable genetic dissection of this complex disorder, and investigation of extended pedigrees from genetically isolated populations may facilitate the detection of specific genetic variants that affect BP as well as its component phenotypes.

Smoking both cigarettes and marijuana is increasingly common among young adults, yet little is known about use patterns, motivations, or thoughts about abstinence. In a U.S. sample, this study explored young adults' severity of cigarette and marijuana co-use, quit attempts, and thoughts about use.
