#1
William T Bryant, John L McNulty
Substance use has generally been related to lower levels of agreeableness and conscientiousness, but has evidenced relationships with other personality trait domains as well, including impulsivity. This study was conducted to determine which trait domain of personality is most related to substance use from the perspective of the Personality Psychopathology Five model (Harkness & McNulty, 1994 ). Archival data were used from 2 clinical settings: 1 outpatient community mental health center and 1 inpatient Veteran's Affairs hospital...

BACKGROUND/OBJECTIVES: Higher fibre intakes are associated with risk reduction for chronic diseases. However, many people find difficulty in consuming sufficient fibre through their diet. Supplements may be an effective alternative. We aimed to investigate the effects of PolyGlycopleX® (PGX®), a proprietary polysaccharide complex and a proprietary Psyllium product (PgxSyl™) (PSY) on diet, body weight and composition in overweight and obese individuals. SUBJECTS/METHODS: This was a double-blind 52 weeks study with 159 people randomized to 3 groups: control (rice flour); PGX (PGX) and proprietary psyllium (PSY)...

The present experiment was designed to assess the effects of seed soaking with 24-epibrassinolide (EBR) on the physiology of Brassica juncea L. seedlings grown under imidacloprid (IMI) toxicity. Application of EBR increased the length of seedlings, dry weight, and pigment contents, polyphenols, total phenols, and organic acids under IMI toxicity. The expression of genes coding key enzymes of pigment, phenols, polyphenols, and organic acid biosynthetic pathways was also studied including CHLASE (chlorophyllase), PSY (phytoene synthase), CHS (chalcone synthase) and PAL (phenylalanine ammonialyase), CS (citrate synthase), SUCLG1 (succinyl Co-A ligase,), SDH (succinate dehydrogenase), FH (fumarate hydratase), MS (malate synthase)...

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 subjective norm (SN) as potential mediators and moderators. SUBJECTS AND METHODS: In 2012, 3,016 volunteers (aged ≥18 years) participated in a community-based survey conducted in the French-speaking region of Belgium...

Beta-carotene adds nutritious value and determines the color of many fruits including melon. In melon mesocarp, β-carotene accumulation is governed by the Orange gene (CmOr) 'golden' SNP through a yet to be discovered mechanism. In Arabidopsis, OR increases carotenoid levels by posttranscriptionally regulating phytoene synthase (PSY). Here we identified a CmOr nonsense mutation (Cmor-lowβ), which lowered fruit β-carotene levels with impaired chromoplast biogenesis. Cmor-lowβ exerted a minimal effect on PSY transcripts but dramatically decreased PSY protein levels and enzymatic activity, leading to reduced carotenoid metabolic flux and accumulation...

There is a growing body of literature recognizing the importance of outpatient psychotherapy. Several studies investigated the efficacy of outpatient psychotherapy and aspects of the health care system under natural conditions. This paper gives an overview of studies from German speaking countries (TRANS-OP-, TK-, PAP-S- and QS-PSY-BAY-study).The results of the different studies indicate both, positive outcome of the therapies (e. g., reduction of symptoms with an average ES of 1,03; improvement of symptoms despite premature termination) as well as an economic benefit (end of treatment depending on treatment outcome and not limited by therapy sessions; extensions of psychotherapy only if patient is highly impaired and therapeutic alliance is positive; high reduction of supply costs and sick leave)...

Phytoene synthase (PSY) catalyzes the highly regulated, frequently rate-limiting synthesis of the first biosynthetically formed carotene. While PSY constitutes a small gene family in most plant taxa, the Brassicaceae, including Arabidopsis (Arabidopsis thaliana), predominantly possess a single PSY gene. This monogenic situation is compensated by the differential expression of two alternative splice variants (ASV), which differ in length and in the exon/intron retention of their 5'UTRs. ASV1 contains a long 5'UTR (untranslated region) and is involved in developmentally regulated carotenoid formation, such as during deetiolation...

Phytoene synthase (PSY) regulates the first committed step of the carotenoid biosynthetic pathway in plants. The present work reports identification and characterization of the three PSY genes (TaPSY1, TaPSY2 and TaPSY3) in wheat (Triticum aestivum L.). The TaPSY1, TaPSY2, and TaPSY3 genes consisted of three homoeologs on the long arm of group 7 chromosome (7L), short arm of group 5 chromosome (5S), and long arm of group 5 chromosome (5L), respectively in each subgenomes (A, B, and D) with a similarity range from 89% to 97%...

Globoid cell leukodystrophy (GLD) is a rare, rapidly progressing childhood leukodystrophy triggered by deficit of the lysosomal enzyme galactosylceramidase (GALC) and characterized by the accumulation of galactosylsphingosine (psychosine; PSY) in the nervous system. PSY is a cytotoxic sphingolipid, which leads to widespread degeneration of oligodendrocytes and Schwann cells, causing demyelination. Here we report on autophagy in the human oligodendrocyte cell line MO3.13 treated with PSY and exploitation of Li as an autophagy modulator to rescue cell viability...

Krabbe's disease (KD) is a fatal neurodegenerative disorder, with the early-infantile form (EIKD) defined by onset of symptoms before age 6 months. Early and highly accurate identification of EIKD is required to maximize benefits of hematopoietic stem cell transplantation treatment. This study investigates the potential for accurate prediction of EIKD based on a novel newborn screening (NBS) tool developed from two biomarkers, galactocerebrosidase (GALC) enzyme activity and galactosylsphingosine concentration (psychosine [PSY])...

Krabbe's disease (KD; also called globoid cell leukodystrophy) is a genetic disorder involving demyelination of the central (CNS) and peripheral (PNS) nervous systems. The disease may be subdivided into three types, an infantile form, which is the most common and severe; a juvenile form; and a rare adult form. KD is an autosomal recessive disorder caused by a deficiency of galactocerebrosidase activity in lysosomes, leading to accumulation of galactoceramide and neurotoxic galactosylsphingosine (psychosine [PSY]) in macrophages (globoid cells) as well as neural cells, especially in oligodendrocytes and Schwann cells...

Carotenoids have essential roles in light-harvesting processes and protecting the photosynthetic machinery from photo-oxidative damage. Phytoene synthase (PSY) and Orange (Or) are key plant proteins for carotenoid biosynthesis and accumulation. We previously isolated the sweetpotato (Ipomoea batatas) Or gene (IbOr), which is involved in carotenoid accumulation and salt stress tolerance. The molecular mechanism underlying IbOr regulation of carotenoid accumulation was unknown. Here, we show that IbOr has an essential role in regulating IbPSY stability via its holdase chaperone activity both in vitro and in vivo...

With increasing evidence suggesting a disparity in female and male offenders in terms of rehabilitative needs, growing concern has been placed on the development of gender-specific services for female offenders. As such, a prison-based psychological gymnasium (PSY GYM), with distinctive features in integrating cognitive-behavioral and positive-psychology concepts to address female offenders' needs, was set up in 2011. The present study aims to introduce the concept as well as present findings to evaluate the overall effectiveness of PSY GYM...

Rootstocks have comprehensive effects on lycopene accumulation in grafted watermelon fruits. However, little is known about lycopene metabolic regulation in grafted watermelon. To address this problem, parallel changes in lycopene contents and the expression of its metabolic genes were analyzed during the fruit ripening of nongrafted watermelon and watermelon grafted onto bottle gourd, pumpkin, and wild watermelon. Results showed that rootstocks mediated the transcriptional regulations of lycopene accumulation in different ways...

Cortical hyperarousal is higher in insomnia sufferers (INS) than in good sleepers (GS) and could be related to an alteration in sleep protection mechanisms, like reduced density or altered characteristics in sleep spindles. The deficient sleep protection mechanisms might in turn enhance underestimation of sleep. This study's objective was to document sleep spindles characteristics in INS compared with GS and to investigate their potential role in sleep consolidation and misperception. Seventeen individuals with paradoxical insomnia (PARA-I), 24 individuals with psychophysiological insomnia (PSY-I), and 29 GS completed four consecutive polysomnographic nights in laboratory...

This article presents the findings of a research study on the construction of a psy scientific field in Argentina during the inter-war period, with a focus on subnational spaces. After 1920, the mental hygiene movement, in its different disciplinary manifestations, became notable in the public sphere, in university education and - belatedly - in healthcare policies, in an expansion that led to the creation of an autonomous field with its own logic. I argue that the creation of this "psy field" - while it was as yet inexistent - was largely due to the strength of sociability networks that facilitated the management of resources and institutional spaces of power, making it possible for the field to become independent and established...
