Emission impacts of left-turn lane on light-heavy-duty mixed traffic in signalized intersections: Optimization and empirical analysis.

Reducing emissions from the transport sector is one of the crucial countermeasures for climate action. This study focuses on the optimization and emission analysis regarding the impacts of left-turn lanes on the emissions of mixed traffic flow (CO, HC, and NO) with both heavy-duty vehicles (HDV) and light-duty vehicles (LDV) at urban intersections, combining high-resolution field emission data and simulation tools. Based on high-precision field emission data collected by Portable OBEAS-3000, this study first develops instantaneous emission models for HDV and LDV under various operating conditions.

Inflammatory markers among adolescents and young adults with bipolar spectrum disorders.

Objective: Despite burgeoning literature in middle-aged adults, little is known regarding proinflammatory markers (PIMs) among adolescents and young adults with bipolar disorder. Similarly, few prior studies have considered potential confounds when examining the association between PIMs and bipolar disorder characteristics. We therefore retrospectively examined these topics in the Course and Outcome of Bipolar Youth (COBY) study.

The effects of parental mood on reports of their children's psychopathology.

Objective: In this study, we aimed to assess whether current mood state (depressed or manic/hypomanic) among parents with a mood disorder would affect their reports of their offspring's psychopathology.

Method: Sixty-five parents with current depression, 42 parents with current mania/hypomania, 181 parents with mood disorder in remission, and their offspring (n = 479, aged 6-18 years) completed assessments of offspring psychopathology as part of the Pittsburgh Bipolar Offspring Study (BIOS). We compared rates of offspring psychopathology assessed using the following: a clinician-administered semi-structured interview with parent and child using the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS); parent-reported Child Behavior Checklist (CBCL); offspring self-reported Youth Self Reports (YSR) for those 11 years and older (n = 250); and teachers' reports when available (n = 209).

Dimensional psychopathology in preschool offspring of parents with bipolar disorder.

Background: The purpose of this study is to compare the dimensional psychopathology, as ascertained by parental report, in preschool offspring of parents with bipolar disorder (BP) and offspring of community control parents.

Methods: 122 preschool offspring (mean age 3.3 years) of 84 parents with BP, with 102 offspring of 65 control parents (36 healthy, 29 with non-BP psychopathology), were evaluated using the Child Behavior Checklist (CBCL), the CBCL-Dysregulation Profile (CBCL-DP), the Early Childhood Inventory (ECI-4), and the Emotionality Activity Sociability (EAS) survey.

Predictors of first-onset substance use disorders during the prospective course of bipolar spectrum disorders in adolescents.

Objective: Substance use disorders (SUD) are common and problematic in bipolar disorder (BP). We prospectively examined predictors of first-onset SUD among adolescents with BP.

Method: Adolescents (12-17 years old; N = 167) in the Course and Outcome of Bipolar Youth (COBY) study fulfilling criteria for BP-I, BP-II, or operationalized BP not otherwise specified, without SUD at intake, were included.

Mood lability among offspring of parents with bipolar disorder and community controls.

Objectives: Early identification of bipolar disorder (BP) symptomatology is crucial for improving the prognosis of this illness. Increased mood lability has been reported in BP. However, mood lability is ubiquitous across psychiatric disorders and may be a marker of severe psychopathology and not specific to BP.

Associations of mental health problems with waterpipe tobacco and cigarette smoking among college students.

Associations between the emerging trend of waterpipe tobacco smoking and mental health among college students have not been sufficiently explored. This study analyzed data collected from 152 academic institutions that participated in the National College Health Assessment during the 2008-2009 academic year to examine associations between mental health and waterpipe tobacco smoking among college students (N = 100,891). For comparison, cigarette smoking was also examined.

Isolation, identification and characterization of a glyphosate-degrading bacterium, Bacillus cereus CB4, from soil.

A bacterial strain named CB4, with highly effective glyphosate degradation capability, was isolated from soil after enrichment. On the basis of the Biolog omniLog identification system (Biolog) and 16S ribosomal RNA (rRNA) gene sequencing methods, strain CB4 was identified as Bacillus cereus. Further experiments were carried out to optimize the growth of strain CB4 and the glyphosate degradation activity by high performance liquid chromatography (HPLC).
