Despite ongoing research on carotenoid biosynthesis in model organisms, there is a paucity of information on pathway regulation operating in the grasses (Poaceae), which include plants of world-wide agronomic importance. As a result, efforts to either breed for or metabolically engineer improvements in carotenoid content or composition in cereal crops have led to unexpected results. In comparis...

BACKGROUND AND OBJECTIVES An experimental design was used to test whether self-reported, psychophysiological and symptomatic stress-responses increase as a function of the underlying vulnerability to psychosis as proposed by vulnerability-stress-models. METHODS Stress-responses of participants with psychotic disorders (PSY, n = 35) were compared to those of participants with attenuated positi...

BACKGROUND AND OBJECTIVE Despite the strength and consistency of the relationship between body mass index (BMI) and quality of life (QoL), a reduction in BMI does not necessarily lead to an improvement in QoL. Between-subject variability indicates the presence of mediators and moderators in the BMI-QoL association. This study aimed to examine the roles of body image discrepancy (BID) and subjec...

Carotenoids are photosynthetic pigments essential for the protection against excess light. During deetiolation, their production is regulated by a dynamic repression-activation module formed by PHYTOCHROME-INTERACTING FACTOR1 (PIF1) and LONG HYPOCOTYL5 (HY5). These transcription factors directly and oppositely control the expression of the gene encoding PHYTOENE SYNTHASE (PSY), the first and ma...

A ssertive community treatment is a well-established model for providing intensive treatment and psy-chosocial rehabilitation services to people with severe and persistent mental illnesses (1). Use of this model has been shown to lead to significant reductions in psychiatric admissions and hospital stays and to improved housing stability, symptoms, and quality of life (2). Although assertive co...

STUDY OBJECTIVES Recent findings suggest few differences in sleep continuity and quality between borderline personality disorder individuals (BPD-I) and good sleepers (GS). Nonetheless, BPD-I show marked discrepancies between subjective and objective sleep measures. The objective of this study was to document sleep in BPD-I, GS, and insomnia sufferers (paradoxical, Para-I; psychophysiological, ...

MMPI-2 clinical, validity, restructured clinical, content, selected supplemental, and PSY-5 scale data from convicted offenders who were incarcerated and referred by community criminal courts were analyzed. Descriptive statistics, including frequency data for high points and well-defined two-point code types were provided. Compared to state and federal inmates, significantly more individuals fr...

Attaining defined steady-state carotenoid levels requires balancing of the rates governing their synthesis and metabolism. Phytoene formation mediated by phytoene synthase (PSY) is rate limiting in the biosynthesis of carotenoids, whereas carotenoid catabolism involves a multitude of nonenzymatic and enzymatic processes. We investigated carotenoid and apocarotenoid formation in Arabidopsis (Ara...
